Análise da percepção de mulheres em situação de vulnerabilidade em relação ao consumo ecossustentável de produtos de higiene menstrual
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-01-30) Silva, Mércia Dark Bastos da; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Gaia, Rossana Viana; http://lattes.cnpq.br/4018992389689693
This study focused on assessing the perception of women in situations of social vulnerability in relation to the eco-sustainable consumption of menstrual hygiene items, with special attention to the environmental impacts associated with the improper disposal of these products, as well as their composition and production process. The methodological path comprised four stages: (1) Systematic Literature Review; (2) Case study, incorporating interviews and focus group; (3) Content Analysis; and (4) Production of Technical and Technological Products, including Manuals for the use and production of reusable fabric pads, Didactic Manual of guidelines for a more sustainable and healthy menstrual cycle, Didactic Material of guidelines for a more sustainable and healthy menstrual cycle, and Social Technology – Reusable Fabric Pads. The results show that, for women in vulnerable situations, environmental perception is not one of the main factors influencing the adoption of reusable items. The lack of information, together with the limited availability of these products and economic conditions, emerged as determinants in this transition process. Thus, the need to democratize information is highlighted, promoting the autonomy of menstruating people and facilitating more accurate and ecologically conscious choices. The creation of educational materials, such as manuals and teaching resources, represents a practical contribution to empowering women, enabling informed and conscious choices regarding menstrual hygiene. These resources seek to disseminate information about the benefits of reusable products, encouraging more sustainable and healthy practices.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-10-20) Carvalho, Juliana Lira Brito de; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Souza, Ronny Francisco Marques de; http://lattes.cnpq.br/7651317326903869; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Gondim, Priscylla Cinthya Alves; http://lattes.cnpq.br/7727315802596668
Due to its composition, post-consumer carton packs have great potential to be used as an input in the manufacture of new products. In this context, this research aimed to analyze the performance of partial replacement of fine aggregate by triturated carton packages in the development of a masonry mortar. The methodology was divided into the following steps: elaboration of a systematic literature review; collection, preparation and comminution of carton packages; characterization of raw materials; definition of the reference and experimental compositions; performance of technological tests; and analysis of results. In the fine aggregate, granulometric analysis was performed. The by-product, Triturated Cartons Packages (ECT), was characterized by Chemical Analysis by X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM). The proportion of 1:6 of volume of cement and fine aggregate was adopted as reference and experimental compositions were determined with substitutions of 5%, 10% and 15% of volume of aggregate by ECT, being molded and tested 5 specimens for each composition. The tests of Consistency Index, Compressive Strength, Water Absorption by Immersion and SEM of Fracture Surface were performed. It was carried out the correlation analysis between the average values of the properties and the percentage of ECT replacement. As for the results of the Consistency Index test, the mortars with ECT replacement showed a small reduction, but they remained in the range presented in the literature. Regarding Compressive Strength, the mortars with replacement of 5%, 10% and 15% showed average values of 7.57 MPa, 6.52 MPa and 6.07 MPa, respectively. Mortars with ECT showed a low rate of Water Absorption by Immersion, when compared to literature data. The statistical analysis revealed that all properties studied have strong correlation with the percentage of ECT replacement. The SEM of the Fractured Surface found the highest number of voids and the presence of microcracks in the samples with the highest percentages of ECT. Finally, the accomplishment of this study proved to be relevant in the context of the development of new technical materials, presenting to the market the mortar with triturated post-consumer carton packages.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-07-21) Alves, Agripino Emanuel Oliveira; Cunha, Ana Catarina Monteiro Carvalho Mori da; http://lattes.cnpq.br/6533002613885833; Valente, Ellen Carine Neves; http://lattes.cnpq.br/5519733594584141; Martins, Ricardo Brainer; http://lattes.cnpq.br/9236216672510518; Dantas, José Oliveira
Storing food is a practice observed since the beginnings of production and agricultural exploitation, it is a fundamental strategy to ensure society's food for a certain period. Currently in agriculture, whether corporate or family, storage is used to ensure the quality of the product and trade. However, these stored and stored foods are targets of pests and insects that compromise production. Thus, measures to control and eliminate these pests are necessary, through various methods, whether with chemical or biological control. Therefore, this work aimed to analyze the bioinsecticide potential of essential oils extracted from Eucalyptus genotypes for the control of storage pests in the production of beans (Zabrotes Subfasciatus) and corn (Sitophilus zeamais), under laboratory conditions, using essential oils from 4 Eucalyptus genotypes (1249, 1250, 1277 and 0292). The oils were tested for repelling action and lethal concentrations for pest control. In the studies of mortality by contact of pest insects, 4 Eucalyptus genotypes were analyzed, with 3 different concentrations being for Z. subfasciatus (1%, 2%, 2.5%), and for Sitophilus zeamais (5%, 10%, 20%), plus one positive and one negative control, with 10 replicates in randomized blocks. For the free-choice repellent action studies on the pest insects Z. subfasciatus and S. zeamais, essential oils from 4 Eucalyptus genotypes were tested with 5 replications for each treatment, in a completely randomized block design. All tested oils showed repellent action on insects and were efficient in the mortality of insect pests Z. subfasciatus and S. zeamais.
Avaliação da qualidade ambiental do complexo estuarino lagunar mundaú-manguaba – CELMM, Alagoas: uma abordagem biológica e da paisagem
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2020-07-24) Silva, Robert Germano Alves da; Mayorga, María Angélica Pérez; http://lattes.cnpq.br/3725581918287088; Romero, Renato de Mei; http://lattes.cnpq.br/9857771457585862; Teresa, Fabricio Barreto; http://lattes.cnpq.br/2706179711969560; Sampaio, Cláudio Luis Santos; http://lattes.cnpq.br/2526336992077506; Araujo, Daniel de Magalhães; http://lattes.cnpq.br/5837261784524743
This dissertation presents two chapters that include environmental assessment methods applied in the hydrographic basins of the Mundaú-Manguaba Estuarine-Lagoon Complex – MMELC. Degradation in CELMM has considerable environmental and socioeconomic impacts on riverside communities. We discuss how environmental, physical and spatial changes are related to chemical descriptors and the ecological response of the ichthyofauna of streams inserted in the system, aiming to test environmental diagnostic instruments for monitoring and managing impacts on rivers and coastal streams. Chapter I presents the application of the Habitat Integrity Index, a local physical assessment (80 m) already consolidated, and two proposals, one for adapting an index for landscape (1.6 km) and another for an index integrated to the two scales to equalize possible distortions. To understand the biological responses to the index values, two ecological estimators were evaluated species richness and percentage of Poecilia reticulata, in the fish community. The results are discussed in order to evaluate the ability to describe the indexes and estimators for local physical, spatial and biological characteristics. In Chapter II, the physical and chemical descriptors of the stream and ecotone were integrated with ecological descriptors. We tested the application of the Abundance and Biomass Curves (ABC) and the W statistic in the biological evaluation to detect environmental disturbance in the streams. The indicator species analysis (IndVal) was used to describe the species that characterize each land use and occupation group, and the Redundancy Analysis (RDA) was performed to identify the chemical and physical descriptors that structure the fish communities for each land use and occupation. In general, the evaluation methodologies used were able to describe the differences in the environments for each land use and occupation and relate the physical and chemical structuring of the streams to the fish community.
Avaliação da viabilidade técnica, econômica e ambiental da produção de piso intertravado com agregado da concha de sururu
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2023-11-30) Tenório, Arthur Amaral Batista; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073; Rapôso, Áurea Luiza Quixabeira Rosa e Silva; http://lattes.cnpq.br/7600867517446003; Peres, Ana Paula da Silva; http://lattes.cnpq.br/9975840346577976
In this study, the sustainable reuse of Sururu shells (Mytella falcata) in civil construction was explored, highlighting not only the approach to environmental problems resulting from inadequate disposal, but also the promotion of local partnerships that generate jobs and boost the regional economy. The present invention consisted of analyzing the interlocking floor with partial replacement of the fine aggregate (natural medium sand) with grains of Sururu shells. A sustainable approach was sought, analyzing technical, economic and environmental feasibility. Detailed physicochemical analyzes were carried out, including Granulometry, X-ray Fluorescence (XRF), X-ray Diffraction (XRD) and Thermogravimetric Analysis (ATG), to characterize the properties of the shells. When defining the concrete mix, a volume ratio of 1:2.33:0.37:2.00:0.43 (cement: sand: crushed stone powder: crushed stone 0: water) was established. Various sand replacement formulations were also examined, varying between 2.5%, 5.0%, 7.5% and 10.0%. During laboratory tests, the results met technical specifications favorably. The C-5% composition presented a compressive strength of 37.87 MPa, meeting the technical requirements established by the standard for concrete pieces intended for paving, which requires resistance equal to or greater than 35 MPa. Water absorption tests demonstrated effectiveness in promoting adequate drainage, with water absorption variations within the acceptable range, remaining below 0.77%. These results highlighted the potential of Sururu shells as a source of technical, economic and environmental interest in the manufacture of interlocking pavements. This study not only contributed to the development of innovative technical materials in the interlocking flooring market, but also emphasized the importance of sustainable practices in construction and reinforces the Circular Economy.
Avaliação de resíduo sólido como mulching alternativo e de agrofilmes na produção de alface na região semiárida de Alagoas
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2021-12-30) Barros, José Anderson Soares; Cavalcante, Marcelo; http://lattes.cnpq.br/0221717690546039; Costa, Joao Gomes da; http://lattes.cnpq.br/2787724876009177; Santos, Márcio Aurélio Lins dos; http://lattes.cnpq.br/0192590447392368
The Soiltain DW® geosynthetic blanket is used in water treatment plants, in water filtration, has a shelf life of three months, in which it is then disposed of in sanitary landfills. Due to its characteristics, it consists of a solid residue with potential for agricultural use, as ground cover. This practice, known as mulching, common in plasticulture in temperate regions, reduces water losses, the incidence of weeds and labor. However, it can promote soil microclimate, especially in tropical and semi-arid regions, causing stress to plants. Therefore, the objective of this research was to evaluate the technical and economic feasibility of the Soiltain DW® geosynthetic blanket as an alternative mulching and the use of synthetic agrofilms in the production of lettuce cv. ‘Veneranda’ in Arapiraca, semi-arid region of Alagoas, Brazil. Four experiments were carried out between June/2020 and March/2021, in a completely randomized design, with four treatments (geosynthetic blanket, white and black polyethylene mulching, and bare soil) and five replications. The technical viability of the coverings was determined from the evaluation, at the end of each experiment, of the soil temperature, stand and morphoagronomic variables. Univariate and multivariate analyzes and Pearson’s correlations were applied. In the analysis of economic viability, indicators were used, from the cash flows between income and expenses, gross income, net income, profitability index and internal rate of return. There was a significant effect (P<0.05) for the interaction Soil cover x Planting times for all variables, except for root mass, indicating that these factors, together, promote changes in the behavior of lettuce cv. ‘Veneranda’. Univariate and multivariate analyzes showed the influence of mulching on lettuce in the four experiments, indicating that white mulching promoted favorable conditions for the evaluated morphoagronomic variables, promoting the highest yields in all cycles (average 19.9 Mg ha-1 ). Temperature is the response variable that exerted the most negative influence, mainly on stand, in which geosynthetic blanket and black mulching showed similarity, due to greater absorption of solar radiation and stand reduction. There is economic attractiveness for all the coverages studied, as there is a result that provides an economic return on the capital invested from the 2nd cropping cycle, when there is economic coverage of the initial investment value and coverage of the minimum attractiveness rate. The economic analysis showed that the geosynthetic blanket promoted the lowest effective operating costs, intermediate net income and lower profitability only than white mulching in the sum of the four experiments. Therefore, the four treatments evaluated are economically viable, especially white mulching. The Soiltain DW® geosynthetic blanket, solid waste, as it is free and reusable, can be used as an alternative mulching on lettuce cv. ‘Veneranda’, in the edaphoclimatic conditions of Arapiraca/AL.
Boas práticas de manipulação, condições higiênico-sanitárias e composição mineral de sururu (Mytella falcata) comercializado em feiras livres de Alagoas
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-07-29) Lucena, Vívian da Silva Santos; Araujo, Daniel de Magalhães; http://lattes.cnpq.br/5837261784524743; Freitas, Johnnatan Duarte de; http://lattes.cnpq.br/4999402869058858; Lopez, Ana Maria Queijeiro; http://lattes.cnpq.br/4034568781881997; Tamano, Luana Tieko Omena; http://lattes.cnpq.br/4206868438935017
Sururu (Mytella falcata) is the main fishing resource of the Mundaú-Manguaba Estuarine- Lagoon Complex (MMELC), being a fundamental product for generating income for tens of thousands of families that live in the surroundings of the lagoons. In addition to its natural propensity to accumulate contaminants present in the aquatic environment, such as toxic metals, the handling of sururu is inadequate, from the subsequent stages of its collection to its disposal in the commercialization places. The present study aimed to carry out a diagnosis of good handling practices, hygienic-sanitary conditions and mineral composition of sururu in street markets in the municipalities bathed by the lagoons that make up the MMELC. For that, a checklist was prepared and applied to guide the observation of the hygienic conditions of the facilities, equipment and utensils used, handling and way of exposing the product, clothing and use of personal protective equipment, and waste disposal, among others, at the fairs in Maceió (Tabuleiro), Marechal Deodoro, Pilar, Satuba and Rio Largo. For the investigation of minerals, samples were acquired from all points of sale found in the fairs of the aforementioned municipalities. After procedures to obtain the extracts by acid digestion, the concentrations of iron (Fe), copper (Cu), manganese (Mn) and zinc (Zn) were analyzed, using the atomic absorption spectrophotometry technique, and lead (Pb), following the corresponding protocol of the Standard Methods for the Examination of Water and Wastewater (SMEWW). With the application of the checklist, it was possible to classify the hygienic-sanitary conditions in all the fairs visited as unsatisfactory. Despite this, it is worth noting that the highest percentages of adjustments were observed at the Rio Largo fair, where the assignment of space for commercialization was conditioned to participation in a training course in good food handling practices, offered by the municipality. The research also involved the application of a questionnaire for the socioeconomic characterization of the vendors. It could be noticed the predominance of female vendors, with low schooling, the sale of sururu and/or other fish as the only source of income, reaching a value close to the minimum wage. As for the micromineral composition, iron showed the highest concentrations in all samples, surpassing by more than fifteen times the values detected for copper, manganese and zinc. Regarding the toxic metal lead, the samples were within the limit allowed in bivalve molluscs. The results obtained with this work confirm the importance of sururu for countless families who sell it in open markets to earn a living and reinforce the need for a joint effort, by the market vendors and those responsible for managing these spaces, to provide the population of these locations with an environment conducive to commercialization of food. In addition, it is necessary for the competent authorities to continuously investigate the levels of highly toxic trace elements in the MMELC, so that the benefits of the consumption of sururu by the population are not counterbalanced by the risk of contamination.
Desenvolvimento de um potenciostato portátil de baixo custo e seu uso em análises ambientais

The planet's population has been growing consistently over the decades. The most recent pro- jections indicate that in the next ten years we will have an increase of 80 million people and that this number will only increase in the following decades. This fact will bring a series of challenges and among them we can mention the need to produce food for this large number of people without compromising the environment even further. Each year, the agricultural harvest in Brazil has been breaking records, in the same way that the use of agricultural pesticides is increasing in the same direction. If these substances are not used appropriately, they will quickly harm the environment and monitoring becomes increasingly necessary. This monitoring is car- ried out through chemical analysis. Raising awareness among new generations about problems related to environmental degradation is important and this can be done in chemistry classes. As is well known, carrying out practices in the laboratory makes learning easier and more effective. In this sense, carrying out practical classes requires essential equipment: a potentiostat. This equipment is expensive and its use is mostly restricted to research laboratories. This research sought to develop a potentiostat capable of carrying out electrochemical analyzes with the main characteristics being its low cost, ease of manufacture and portability where its focus is not on carrying out analyzes with great precision to be used in classes for the quantification of internal contaminants. -environmental stress. We searched the literature for projects that included some of these characteristics to promote adaptations and improvements with the aim of minimizing costs. The equipment developed was subjected to calibration using the electrical resistance method to verify its compliance with Ohm's law. It presented a difference of +/- 0.14% in rela- tion to a fictitious resistance compared to a difference of +/- 0.1% presented by a commercial potentiostat. Improvements in the future such as improving the software with the insertion of new electrochemical techniques, modifying the microcontroller (Arduino pro mini, or similar and developing another communication cable.
Hotelaria e desenvolvimento sustentável: uma análise contemporânea à luz das práticas ambientais
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-04-29) Maia, Carolina Ferreira Simon; Tonholo, Josealdo; http://lattes.cnpq.br/6333407087554681; Lages, Vinicius Nobre; http://lattes.cnpq.br/0525380988317234; Gomes, Fábio Guedes; http://lattes.cnpq.br/6641021807409592; Rocha, André Leite; http://lattes.cnpq.br/1335590978899886
The hotel industry, important economic activity for any location exploiting tourism, generating employment and income at all levels of professional qualification, and provides opportunities for several direct and indirect jobs. In addition to this is its close relationship with the environment, revealing itself as an opportunity for competitive differentiation in its offer. At the same time, it has a high consumption of resources for its operation, the sector has recognized potential to contribute to sustainable development (SD). It can reduce its negative environment impacts and meet the demands of a market that is increasingly sensitive to these issues. The present study carried out a systematic literature review (SLR) and a survey of the actions employed by the hotel sector, with the objective of analysing the existing world literature and business scenario on the adoption of environmental practices/ technologies, considering the last five years. The methodology used was an exploratory-descriptive study, developed in two stages: (i) SRL that resulted in a portfolio of articles, enabling bibliometric and systematic analysis through the reading of the articles guided by the three dimensions of SD; and (ii) research on the sites of the largest global and Brazilian hotel chains to identify the corporate actions that are being runned on this topic. With the results, it is observed that in the recent years there has been an increase in the number of studies and initiatives related to sustainability in hotel enterprises, with the adoption of socio-environmental practices/ technologies and effective changes in their organizational cultures. A significant number of environmental certifications and organizations acting as a reference on this topic were also identified. In the business sphere, it became evident that while the hotel sector worldwide demonstrates strong commitment to sustainability, in Brazil national enterprises cannot yet be perceived as protagonists in the irreversible process of global business dynamics. If there are actions, they are not being shared with society structured and systematically. Among other possible models, the Technical Guide is presented as a Technological Technical Product (TTP) generated from this study.

In Brazil, sewage sludge is generally sent to the landfill, compromising the useful life of the landfills, as it occupies the place of other solid domestic waste. Considering the nutrient richness of the sludge, and its agricultural recycling as a technical, economic and environmentally safe alternative, the present work developed a technique for agricultural recycling of sewage sludge generated by the sewage treatment plant in the municipality of Igaci, chosen for having its sewage treatment plant built recently (August/2018). The methodological procedures were divided into two stages, where the first is carried out through the Geographic Information System (GIS), in which maps were built showing the areas of the municipality where sewage sludge can be applied for agricultural purposes. Finally, the present work sought to calculate the necessary sludge dosage in agricultural areas, for the main crops used in the municipality. With this, it is intended to carry out the recycling of sewage sludge in the municipality of Igaci, analyzing the places where they must be inserted, and the necessary dosage of biosolids for each type of crop that can be used in agricultural areas. This study enables a good management of the sludge from the sewage treatment plant in the municipality of Igaci, favoring soil recovery and the optimization of agriculture.
Metodologia para produção de moradia em assentamentos urbanos informais com incorporação de Tecnologia Social: estudo de caso na Favela Sururu de Capote no Município de Maceió/AL
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-01-25) Vitorino, Natiele Vanessa; Cunha, Mônica Ximenes Carneiro da; http://lattes.cnpq.br/1775024859845111; Cavalcanti, Fernando Antonio de Melo Sá; http://lattes.cnpq.br/4407657668950931; Marques, Sheyla Karolina Justino; http://lattes.cnpq.br/3917387578549073
Housing shortage is one of the biggest urban challenges in Brazil. Because of it, many families have been build precarious housing in clandestine or environmentally fragile areas, despite the housing programs that have been developed over the years, as the Favela Sururu de Capote, in Maceió/AL. Community involvement searching by solutions is fundamental to generate protagonism and social inclusion. Social Technology (ST) emerges in this context and involves of products, methods and techniques produced in interaction with the community and appropriated by them, uniting traditional knowledge with technical-scientific knowledge. Social Technology (ST) incorporation in housing is still an atypical topic among researchers. This work objective to propose a methodology for the production of housing in informal urban settlements with the Social Technology incorporation. As a research strategy, a qualitative approach was chosen. The methodological course involved three stages: (1) Systematic Literature Review (SLR); (2) Rapid Participatory Urban Diagnosis (DRUP); and (3) Proposal for a methodology for the production of housing with ST incorporation. By the SLR results, it was found that the ST incorporation in the housing problem is a recent theme. It was also possible to identify indicators, some technologies for houses construction and tools for data collection, like the DRUP. By the field research, it was possible to identify the social and environmental community problems and make the residents' needs survey. From the data obtained, it was possible to list indicators related to environmental and social aspects. In turn, the indicators found in the RSL and those defined from the DRUP were fundamental to support the proposed methodology for the production of housing with the ST incorporation, involving four stages: planning, development, application and reapplication. It is expected that the methodology developed in this research can contribute to the production of housing with the Social Technologies incorporation in informal urban settlements.

Urban Solid Waste (USW) is one of the problems that is becoming increasingly present in society, due to the increase in generation to be active in consumption. Thus, this dissertation aimed to create an application for smartphones, +ecoponto together with the creation of informative content for digital tools (Instagram and Youtube) combined with environmental education, as strategies to support the management of MSW, in the municipality of Arapiraca - AL. The research is also research in two chapters, methodological composition based on a qualitative approach, with an exploratory and descriptive character as a case study. The data for the acquisition of information were bibliographically obtained through on-site and personal visits through the WhatsApp application (the latter means, due to the pandemic period). The procedures were divided into three stages. Initially, a prototyping of the application was carried out to display the places for solid waste disposal in the municipality. Data collection was carried out using a form on Google Forms, with a selective collection to profile the population, the data were treated and interpreted. Information on the points was sought for mapping the region with the City Hall, associations and cooperatives to incorporate the data into the application, emphasizing that the realization of visit data was due to the period of the pandemic. The work carried out in the creation of the application, ecoponto, which will be made available to the Arapiraquense population, and in the preparation of didactic material (video and information cards) shared on Instagram and Youtube media, with dissemination in profiles of cooperatives and associations of collectors in the city. In the course of the dissertation, Chapter I presents methodologies and steps for the elaboration of the application of its functionalities. Chapter II presents an approach on the use of social media as a tool to help the management of MSW, for the dissemination of content related to environmental education and the importance of associations in Arapiraca – AL
Monitoramento de glifosato no Complexo Estuarino Lagunar Mundaú-Manguaba (CELMM) por cromatografia de íons com supressão química e detector de condutividade
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-07-29) Novais, José Fábio Felix de; Lima, Phabyanno Rodrigues; http://lattes.cnpq.br/9334426018309756; Lopes, Cleylton Bezerra; http://lattes.cnpq.br/4000861323429729; Lima, Sarah Kelly Melo Cavalcante Rodrigues; http://lattes.cnpq.br/0820477133147241
The Estuarine Complex Lagunar Mundaú-Manguaba - CELMM has relevant cultural, gastronomic, social, economic and environmental importance for the cities that surround it. The main economic activity developed that encompasses its surroundings comes from the sugarcane agroindustry, responsible for the use of tons of pesticides every year in the monoculture of sugarcane. In the last 4 decades, the tributaries of the CELMM have been receiving inorganic contaminants (nutrients from fertilizers) from the sugarcane industry and agribusiness, through leaching caused by the hydrological cycle, feeding streams, rivers and channels that flow into its bed, acting as a vehicle transporter by agricultural flow of ions, with a tendency to modify the physical, chemical and biological characteristics of its ecosystem. However, for this reason, there is a need for detailed studies focusing on the determination of pesticides in the CELMM basin region. In this sense, among the various types of pesticides sold in Brazil, those products with a broad spectrum of action, the so-called non-selective, systemic and post-emergent, such as the herbicide glyphosate N-(phosphonomethyl) glycine, stand out. In this perspective, 8 samples were collected at 8 points of surface water up to 20 cm deep in the streams and channels of the agricultural region that flow into 4 municipalities that make up the CELMM, being collected in the period of the sugarcane harvest to determine the following ions of interest for public health by ion chromatography, such as glyphosate and other anions (fluoride, chloride, nitrite, bromide, nitrate, sulfate and phosphate) and cations (lithium, sodium, potassium, ammonium, magnesium, calcium). The municipalities in the state of Alagoas monitored were: Maceió/AL, Marechal Deodoro/AL, Pilar and Santa Luzia do Norte/AL. The analytical results did not show glyphosate concentrations above the limits of quantification (LQ) determined in the calibration curves of the monitored ions, which are (0.05 mg L-1), whereas other anions and cations that were quantified have concentrations below the Maximum Permissible Value (MPV) in accordance with current Brazilian legislation.

In recent decades, Brazilian agribusiness has grown positively, placing the country as one of the largest producers and exporters of food, resulting in a potential user of pesticides (agrochemicals) in vegetable crops, thereby reducing losses. However, in terms of health and food safety, there are no significant benefits in relation to the economic sector in Brazil, since poisoning by agrochemicals can be directly or indirectly, leaving the population exposed to acute and chronic diseases. The risk of contamination of these compounds in water resources is also an environmental and public health concern. In this context, the study aimed to estimate the level of contamination of water from domestic supply wells by agrochemicals applied in an urban area in the metropolitan region of the city of Maceió-AL, whose analyzes were carried out according to criteria proposed by the Environmental Protection Agency. - EPA, using liquid and gas chromatography techniques coupled with mass spectrometry. As a result, it was observed that during this study the 27 active principles evaluated were below the limits allowed by Brazilian legislation. As for the risk of water contamination, even with results below the recommended limits, it is recommended that there is a need to implement environmental monitoring programs and measures aimed at protecting public health, since agrochemical parameters are currently established in the evaluations the potability of water for human consumption. The treatment and control of water are, for vital reasons, ways of mitigating the spread of diseases or complications, satisfying the quality standards established for the distribution of water for human consumption.

Several sectors of society demand essential natural resources to maintain life, so the balance between the use and replacement of these resources is essential. In this context, the creation of protected areas can work as an excellent instrument of environmental management, especially in the provision of ecosystem services. Private Natural Heritage Reserves are private conservation units with the objective of achieving these assumptions. The objective of this study is to understand and characterize the processes related to creation and the uses given to this typology of protected area in Alagoas. A survey of data (spatial, bibliographic, documentary and interviews) was carried out on the reserves. Information from interviews with representatives of public agencies and civil society responsible for the creation and implementation, in addition to the owners or managers of the reserves, was analyzed. With this, we sought to identify three main points: 1. History of creation of RPPNs; 2. Description of the reserves, with administrative and maintenance aspects, conservation, biodiversity, threats; 3. Public and private uses of the reserve. As a result, we hope to assist in the composition of scientific information about them, once the existence of gaps in freely accessible data in official electronic addresses has been identified. As for the partial results obtained so far, it is possible to observe the identification of all the seventy-six existing reserves in the state, as well as the classification by domains and by stages of creation. From this, a higher concentration of reserves was identified in the Atlantic Forest domain compared to the Caatinga domain. This abundance of reserves, mainly in the Atlantic Forest, may be linked to actions by several sectors: the public ministry, the state environmental agency, non-governmental organizations active in this biome, as well as the initiative of the agro-industrial sector, since several protected areas are owned by the sugar and ethanol industries. Therefore, the emergence of RPPNs in the state of Alagoas was motivated by factors such as the institution of SNUC itself; the incentive to landowners through environmental compensation, in the form of a suggestion in accordance with the IMA and MP; regularization through decree 3050/2006; the need for forested areas to implement projects for the reintroduction of endangered species and actions to publicize this type of reserve among landowners carried out by IPMA. All these factors added to the development of the Mais RPPNs, Pró-Reservas plans and all the effort made by the NGOs, as well as a good relationship between the actors involved to facilitate the reduction of bureaucracy in the processes in public agencies were essential for the installation of RPPNs in the state.

In an era driven by the technology of the fourth industrial revolution, producing on a large scale and maintaining quality is what everyone expects. The need for food production on the planet is increasing, with United Nations projections that, from 2050 onwards, the world population will exceed 10 billion people. In view of this factor, humanity needs to develop new agricultural techniques to provide, efficiently and on a large scale, healthier food to humanity. However, the availability of processed, transgender and industrialized foods poses a challenge for those who seek to take care of their health without losing the practicality of the modern world. Keeping these factors in mind, farmers, engineers and scientists have sought to implement new cultivation techniques by implementing modern technologies adorned with sustainable development. Faced with these challenges, the present work aimed to develop a system composed of hardware and software for the intelligent indoor cultivation of vegetable gardens with artificial lighting using the internet of things. The research methodology involved three stages: 1) Systematic Literature Review to investigate equipment and techniques used in the cultivation of indoor vegetable gardens; 2) Development of an architecture composed of hardware and software for intelligent indoor cultivation of vegetable gardens with artificial lighting; 3) Validation of the proposed architecture based on an experiment consisting of the installation of hardware and software devices to monitor the stages of indoor vegetable cultivation. For the experimentation stage, lettuce and beet microgreens, red cabbage and mustard were planted in a cabin that monitors the environmental variables of temperature and humidity inside and outside the cabin and automatically monitors the air fans, air and LED panel remotely via Wi-Fi, Zigbee and Bluetooth on the Tuya Smart app. The results obtained point to a system composed of hardware and software with full vegetable production capacity through its complete development from sowing, germination, transplanting and harvesting, producing beetroot and red cabbage microgreens without the emergence of fungi or any other insect problems during the observation period.

(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2024-01-31) Nascimento, Marco Antonio Diniz do; Calheiros, Altanys Silva; http://lattes.cnpq.br/9353777923030637; Nascimento, Melchior Carlos do; http://lattes.cnpq.br/3304840348256677; Monteiro, Kleython de Araujo; http://lattes.cnpq.br/0601272599787430
The Caatinga region undergoes significant modifications in its natural environment, primarily caused by the removal of native vegetation cover, often resulting from illegal deforestation for various purposes and soil exploitation. Therefore, our study presents results on the monitoring of areas covered by native Caatinga vegetation in the Immediate Microregion of Delmiro Gouveia, which includes the municipalities of Delmiro Gouveia, Água Branca, Mata Grande, Pariconha, Piranhas, Olho D’Água do Casado, and Inhapi, located in the hinterland of the Alagoas state. To do so, the research method employed to achieve the results of territorial distribution and quantification of Caatinga vegetation cover is divided into: (i) analysis of the Normalized Difference Vegetation Index - NDVI and Enhanced Vegetation Index - EVI; (ii) analysis of areas adjacent to the 'canal do sertão' (aqueduct project) within a radius of 5 km; (iii) cross-referencing areas embargoed by environmental agencies due to illegal vegetation suppression; and (iv) monitoring land use for the years 2002 and 2022. To obtain the results, images from the Landsat 7 satellite were used, with a spatial resolution of 15 meters (panchromatic) at a cartographic scale of 1:25,000. The analyses obtained through NDVI and EVI did not show significant differences in the distribution of Caatinga vegetation on the ground. The pixel values corresponding to the presence of Caatinga vegetation varied from 0.8 in the year 2002 to 0.6 in the year 2022 for NDVI results, and from 18.8 in the year 2002 to 16.5 in the year 2022 for EVI results. On the other hand, the land use monitoring reveals a 31% reduction in Caatinga vegetation between the years 2002 and 2022, along with anthropized areas, highlighting a 23% growth in agropastoral areas and 11% in exposed soil. In conclusion, the methodology applied on this study yielded satisfactory results for assessing vegetation cover, providing outcomes of environmental, social, and academic interest.
Viabilidade técnica da manta geossintética na produção de pimentão em função de diferentes lâminas de irrigação em Arapiraca, Alagoas.
(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2020-06-26) Oliveira, Sílvio Serafim; Cavalcante, Marcelo; http://lattes.cnpq.br/0221717690546039; Calheiros, Altanys Silva; http://lattes.cnpq.br/9353777923030637; Prates, Fabiano Barbosa de Souza; http://lattes.cnpq.br/6530012770891274; Santos, Márcio Aurélio Lins dos; http://lattes.cnpq.br/0192590447392368
Pepper is among the ten most important vegetables in terms of economic value in Brazil, with Alagoas ranking 7th in the Northeast. The Arapiraca city is responsible for the production of 43.6% of the pepper produced in the State. However, due to the city being inserted in the semiarid region, the use of efficient techniques of use and management of water and soil is of great importance for agricultural activity. For these reasons, aimed, with this research, to evaluate the technical viability of the Soiltain® DW woven geosynthetic under three irrigation levels, in the cultivation of peppers in Arapiraca, Alagoas. The experiment was conducted in split-plot design, being in the main plots three irrigation levels (60, 100 and 150% of ETc) and in the subplots, four soil coverings (SoilTain® DW woven geosynthetic, bare soil, synthetic white and organic Mulchings), with five replications, totaling 12 treatments, with five replications. Agromorphological variables, components of pepper production, and soil temperature were evaluated. There was a significant interaction between the treatments, in which the woven geosynthetic showed superior results to white Mulching in relation to plant heights, stem diameter, leaf width and water use efficiency in the three irrigation depths, together with the bare soil treatments and organic Mulching. The 150% ETc level favored higher plant mortality during the crop development period, with a reduction in the stand, reducing yield, which ranged from 40.33 t ha-1 for white Mulching to 57.18 t ha-1 for organic Mulching. The soil temperature negatively influenced the development of the crop, being higher in white Mulching in all evaluations. The blanket also promoted greater profit and lower production cost and, likewise, the 100% ETc. level. The SoilTain® DW woven geosynthetic is viable as an alternative Mulching, and it is recommended to associate it with the 100% ETc level.

In water treatment plants (WTP) procedures are developed that result in water potability, generate a residual by-product called WTP sludge, with polluting potential. The association of WTP sludge to commercial substrates seedling production is presented as an ecologically correct and economically viable alternative. The objective of this research was to analyze the technical feasibility of using WTP sludge added to four commercial substrates in the production of seedlings of five lettuce cultivars and their performance in the field, in Arapiraca, semiarid region of Alagoas. The research was divided into two stages. The 1st, at greenhouse level, the experiment was installed in a completely randomized design, 4 x 4 x 5 factorial scheme, considering the four commercial substrates (Pindstrup®, Vida Verde®, Bioplant 434® and Bioplant 401®), four levels of substrate replacement by sludge (0, 20, 40 and 60%) and five lettuce cultivars (‘Veneranda’, ‘Camila’, ‘Elba’, ‘Vitória Verdinha’ and ‘Diva’), with four replications. It was observed that the percentage of emergence was influenced by the addition of sludge, mainly in the Pindstrup substrate and at a dose of 60%, with 0% emergence. The seedling quality index (SQI) was influenced by the sludge doses, with the addition of up to 20% being recommended. In the 2nd experiment, the seedlings produced in the 1st stage were evaluated at field level, adopting a randomized block design, 3 x 3 x 5 factorial scheme, with three commercial substrates (Vida Verde, Bioplant 434 and Bioplant 401), three levels of substrate replacement by sludge (0, 20 and 40%) and five lettuce cultivars (‘Veneranda’, ‘Camila’, ‘Elba’, ‘Vitória Verdinha’ and ‘Diva’). Biometric variables were analyzed at harvest time, 25 days after transplanting. A triple interaction was observed for plant height, leaf length and yield. In general, all cultivars showed similar productivity (P>0.05) in up to 20% of sludge inclusion, regardless of substrate. Cultivars that had reduced SQI, in the 1st experiment, resumed growth and had similar productivity (0 up to 40% sludge), such as cultivars ‘Camila’ (Vida Verde), ‘Veneranda’ and ‘Diva’ (Bioplant 434) and ‘Veneranda’, ‘Camila’, ‘Elba’ and ‘Vitória Verdinha’ (Bioplant 401). The inclusion of sludge to replace the commercial substrate presents technical feasibility with potential for cost reduction and environmental preservation
