Data collection should preferably be carried out close to the stratum of plant cultures, as this way obtain reliable data on the microenvironment where the plant is located. The objective this study was to develop a low-cost data collection system to obtain parameters related to luminosity, soil moisture, air humidity and temperature in an agricultural environment. The specific methodology of product development and Arduino prototyping platform were used to assemble the Datalogger system. Functional tests were carried out in two greenhouses A1 and A2 for a period of 24 hours. The system design, with the use of sensor supports, allowed the collection of data without interruption and with adequate accuracy. The Arduino platform and accessory sensors proved to be perfectly applicable for data acquisition and storage in greenhouses. The developed Datalogger prototype showed a cost reduction of 600 to 3000% compared to components available on the market with similar functionalities.</p> 2021-08-31T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/962 PERFORMANCE OF PLOT HARVESTER ON SOYBEANS WITH DIFFERENT DISPLACEMENT DIFFERENT SPEED 2021-07-26T18:26:05+00:00 Matheus Danieli matheusdanimaider@gmail.com Allan Remor Lopes allanremorlopes@gmail.com Marcelo Dotto marcelo.dotto@unisep.edu.br Elouize Xavier elo231@hotmail.com André Bressiani Machado admachado94@yahoo.com.br Vinicius Eduardo Schiavini schiavinee@hotmail.com Camila Moreno Giarola camila.giarola@edu.unipar.br Kelli Pirola kelli_pirola1@hotmail.com <p>The mechanized harvesting of soybean is fundamental tool in the production process of this crop, and if not performed properly, it can result in severe mechanical damage to the grains, causing significant losses at harvest. This concern with harvest must also be taken into account in experimental fields, when plot harvesters are used. The aim of the present study was to assess losses occurring in mechanized harvesting with plot harvester with diffent displacement speed. Combine header, thresing and total losses were assessed. In addition, the impurity number of pods and the moisture content of the grains were evaluated, with displacement speeds of: 2, 4, 6 and 8 km h<sup>-1</sup>. The increase of displacement speed provided less losses in mechanized harvesting of soybean. The number of pods, such as impurities and humidity, were also influenced by the increase in displacement speed.</p> 2021-08-31T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/967 ANALYSIS OF THE SPATIAL VARIABILITY OF THE TEMPERATURE HUMIDITY INDEX IN RIO GRANDE DO SUL AT DIFFERENT TIMES 2021-07-26T18:29:51+00:00 Zanandra Boff de Oliveira zanandraboff@gmail.com Alberto Eduardo Knies albertoek@gmail.com Sidinei Zwick Radons sidineiradons@gmail.com Eduardo Leonel Bottega eduardo.bottega@ufsm.br <p>This study aims to analyze the spatial variability of the temperature and humidity index (THI) in RS at different times of day. The study was carried out for forty-two municipalities. The THI was calculated using temperature and relative humidity data (period 2000 to 2020). Once the spatial dependence was detected, the thematic map of the spatial distribution of the ITU was produced by means of ordinary kriging at 3-hour intervals (5-7; 8-10; 11-13; 14-16; 17-19; 20 -22; 23-1; 2-4 h). In the interval between 8 and 10 am and between 8 pm and 10 pm, the index is indicative of comfort throughout the territory; between 23 and 7 h there is discomfort due to cold stress (THI&lt;60) in most of the state and, between 11 and 19 h, there may be some type of discomfort due to heat stress (THI&gt;70) in most of the state of Rio Grande do Sul.</p> 2021-09-21T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/974 VERIFICATION OF THE PRODUCTION OF WTP SLUDGE AS A FUNCTION OF THE QUANTITY AND QUALITY OF RAW WATER 2021-08-03T19:43:10+00:00 Lucas Avelino Reis Santos lucassantos_a@hotmail.com Denise Conceição de Gois Michelan denise_gois@yahoo.com.br Taynar Mota Jesus taynar.mota@gmail.com <p>Quantifying the sludge produced in water treatment plants (WTPs) is a fundamental step to know how much of this waste is improperly released into water sources and to plan its proper final disposal. This article discusses the comparison between three empirical methods for estimating the amount of sludge generated in two WTPs with different consumption of chemical products in water treatment for the municipality of Aracaju. The research was carried out in order to verify if there were differences in the results between the years 2016 to 2019, to compare the production estimates for each WTP and to analyze the influence of variations in the qualitative parameters of raw water and the addition of chemical products. It was found that empirical equations that consider a greater number of variables are the most appropriate for WTPs where treatment is more complex, while simpler equations can be suitable for WTPs that use few chemicals.</p> 2021-10-01T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/1021 EFFECT OF THIAMETOXAN INSECTICIDE ON COFFEE SEEDLINGS 2021-08-17T14:31:25+00:00 Welinton Blener Pereira de Assis welintonblener78@hotmail.com Kleso Silva Franco Júnior kleso.junior@yahoo.com.br Giselle Prado Brigante giselle.brigante@gmail.com Tamara Machado da Silva tamara_machado@live.com Márcio de Souza Dias marciodesouzadias2013@gmail.com Natália Scalco Ferreira nataliascalco85@gmail.com <p>The objective of this research was to evaluate the growth of coffee seedlings using the insecticide Thiamethoxan at different dosages on <em>Coffea arabica</em> L seedlings. Two formulations of the insecticide Thiametoxan were used, dispersible granules (WG A) and granules (GR B), both diluted in water and treatments consisting of doses: 0% (control), 50%, 100% and 150% for both versions of the insecticide. The experimental design used was in randomized blocks, in a 2 x 4 factorial scheme, with three replications. After 180 days, the following parameters were evaluated: height, length of root and shoot, fresh and dry biomass of the root system and shoot. The use of Thiametoxan, in two applications, influenced the development of the root system, plant height, length and mass of the aerial part of the coffee seedlings in comparison with the control, not being observed the effect of different dosages of Thiametoxan in the development of the root system.</p> 2021-10-01T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/1017 USE OF FUZZY LOGIC TO OPTIMIZE FERTILIZER APPLICATION IN THE RADISH 2021-09-07T12:13:55+00:00 Emmanuel Zullo Godinho emmanuel.godinho@unesp.br Fernando de Lima Caneppele caneppele@usp.br Hélio Vagner Gasparotto hélio.vagner@unesp.br <p>The aim of this study was to develop a fuzzy-rules-based model to evaluate the effects caused by varying the dosages of two soil fertilizers (mineral and organic) on root diameter. Fuzzy logic is a method that presents a language, more appropriate to everyday life, as the sky is cloudy. For the input variables of this system, mineral and organic fertilizers were used, for the output the root diameter, in cm. After optimizing the input rules, it can be seen that for the application of fertilizers (mineral and organic) the best dosages were 15 to 60 and 20 to 60 g m<sup>-2</sup>, respectively. With this application of fuzzy rules in real data, these benefits can be taken to those involved in the radish production chain, thus resulting in a reduction in product dosages and improving its final profitability.</p> 2021-10-01T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/961 MACROAGGREGATION OF A PALEUDALF AFFECTED BY CAVITATION INTENSITY AND MANAGEMENT SYSTEMS WITH COVER PLANTS 2021-09-07T12:15:57+00:00 Érika Andressa Silva andressaerikasilva@gmail.com Micael Stolben Mallmann micaelstolben@gmail.com Monike Andrade Pereira monikeandrade.pereira@hotmail.com Sarah Severo Pons sarahsevero@hotmail.com Felipe Dalla –Zen Bertol fe_bertol@hotmail.com Dalvan José Reinert dalvan@ufsm.br José Miguel Reichert reichert@ufsm.br <p>Ultrasonic-based techniques allow the prediction of the energy required to break the aggregate and have been more commonly used to measure the stability of aggregates. Although they result in the same applied energy, certain combinations of time and power might correspond to different intensities of cavitation. Consequently, different responses in aggregation indexes can be obtained with different configurations of ultrasound techniques. Thus, this work was carried out to evaluate the effects of cavitation intensity in the distribution of aggregates of a Paleudalf under management systems with cover plants and to compare aggregate stability determination methods (ultrasound versus wet sieving). Aggregate samples of the BS (bare soil), OT (black oat + forage turnips) and OV (black oat + hairy vetch) treatments were exposed to ultrasonic irradiation in different combinations of potency and time: (U1) 74.5 W/4 s; (U2) 49.7 W/6 s; (U3) 74.5 W/10 s and (U4) 49.7 W/15 s. After each sonification, the samples were passed in the same set of sieves used in the standard method of wet sieving -WS (8.00 - 4.76, 4.76 - 2.00, 2.00 - 1.00, 1.00 - 0.25 and &lt; 0.25 mm) and the geometric mean diameter (GMD) and mass-weighted mean diameter (WMD) were calculated. The amplitude of vibration exerted a greater influence on soil breakdown than the total energy applied. Compared to the ultrasound method, in the WS method observed higher percentage of retained aggregates in the size class 8-4.76 mm and, consequently, greater aggregation indexes GMD and WMD.</p> 2021-10-05T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas https://seer.tupa.unesp.br/index.php/BIOENG/article/view/1033 PERFORMANCE OF SUGARCANE CULTURE PRODUCTION IN THE MAIN PRODUCING STATES 2021-09-15T11:13:27+00:00 Lazaro Quintino Alves lazaro.alves@aluno.unifenas.br Petrus Narciso Franco petrus.franco@aluno.unifenas.br Willian Aparecido Leoti Zanetti willian.zanetti@unesp.br Bruno César Góes brunogoes2211@gmail.com <p>The cultivation of sugarcane is one of the main sources for the production of sugar and ethanol in Brazil, measuring growth in the sector, especially after the regulation of flexfuel motor vehicles.

This study's motivation is to find a solution for lacking freshwater, converting brackish and seawater to potable water. The main goal was to produce potable water with high-efficiency production using solar energy. The system's main components were the absorber plate painted black, glass cover, insulation, and vessels to collect fresh water. The absorber plate is painted black to absorb solar radiation, preventing its reflection. The plate delivers higher temperatures for saline water to be evaporated and condensed afterward. The basin liner was made of an iron sheet, and the cover is made of ordinary glass, while the basin was covered with glass using silicon rubber. We used 30-degree single slope solar to identify the efficiency of using black stone without using black stone (control). The results showed that the maximum output with black stone and without it was respectively 750 ml and 600 ml; therefore, the use of black stone can increase the productivity for the single slope solar still.</p><p><strong>Keywords:</strong> Solar collector; Potable water; Brackish water.</p> 2021-10-14T00:00:00+00:00 Copyright (c) 2021 Revista Brasileira de Engenharia de Biossistemas
