Título: ZONEAMENTO GEOVITÍCOLA DE UVAS FINAS PARA A REGIÃO DO DISTRITO FEDERAL, BRASIL Autor(es): Rezende, Leandro Teixeira de Primeiro Orientador: Amaral, Uirá do Abstract: The Federal District presents its entire territory in the Cerrado Biome at an average altitude of more than 1000 m and an ideal temperature range for growing fine grapes in some months of the year. This fact, associated with public-private investment, launched in 2024 the “Wine Route or Grape Route” in the Federal District and Surrounding Region. Given this context, the objective of this work was to characterize the climatic potential of this region for the production of wine grapes, using the Geoviticultural Multicriteria Climatic Classification System, based on geoviticultural indices: Heliothermal Index (HI); Night Cold Index (IF) and Drought Index (IS). The data were obtained from an automatic meteorological station belonging to the National Institute of Meteorology (INMET) located in the Federal District over a series of 10 years (2015 to 2024).To obtain the climatic indices and their respective classes, the data were separated into two periods: “PF” formation pruning (Sep/Feb) and “PP” production pruning (Feb-Jul). The results obtained for the periods evaluated were: PF (Sep-Feb) - IH+3; IF-1; IS-2 and PP (Feb-Jul) - IH+2; IF+2 and IS+1. The indices for the grape harvest period were favorable for greater fixation of sugars and pigments. The Federal District presented geoviticultural indexes equivalent to countries with a tradition in wine production both in the Southern Hemisphere and in Europe.

Título: CONTROLE DO TEOR DE UMIDADE NA SECAGEM DE GRÃOS DE SOJA: ANÁLISE COMPARATIVA ENTRE ARMAZENAMENTO E PROCESSAMENTO INDUSTRIAL EM UMA UNIDADE ARMAZENADORA Autor(es): Lopes, Eduarda Santos Primeiro Orientador: Miranda, Raiane Ferreira de Abstract: This study aimed to analyze the control of moisture content in soybean grains in a storage and industrial unit, highlighting its influence on post-harvest quality and processing performance. The research was carried out at the Olvego – Óleos Vegetais de Goiás LTDA unit, located in the municipality of Pires do Rio, Goiás, Brazil, covering the stages of reception, classification, drying, cooling, storage, and industrial processing. Operational data were collected from control spreadsheets of grain reception and drying systems, including variables such as moisture content, impurities, and grain quality. The results showed that the received soybeans presented significant variations in moisture content, often above safe storage levels, making the drying process essential. It was observed that the dryers played a fundamental role in reducing moisture content, allowing the grains to meet both storage safety requirements and industrial processing standards. In addition, inadequate moisture control may compromise grain quality, favoring deterioration processes such as heating, microorganism development, and quantitative and qualitative losses. Therefore, it is concluded that moisture control is a strategic factor in the soybean production chain, being essential to ensure grain preservation, reduce losses, and optimize industrial yield. This study contributes to improving postharvest management practices, emphasizing the importance of continuous monitoring and operational control in storage units Editor: Instituto Federal Goiano Tipo: Trabalho de Conclusão de Curso

Título: UTILIZAÇÃO DE CAMA DE FRANGO PARA A REMOÇÃO DE CROMO E NÍQUEL EM AGUAS RESIDUÁRIAS Autor(es): Silva,, Everton freire Primeiro Orientador: Souza, José Antônio Rodrigues Primeiro Membro da Banca: Astoni, Débora Moreira Segundo Membro da Banca: Silva, Ellen lemes Abstract: One of the major challenges in today's industrial landscape is the improper disposal of waste, especially waste containing heavy metals, which cause significant contamination of water bodies, affecting the ecosystem and quality of life. Heavy metals, even in low concentrations, can be cytotoxic, carcinogenic, and mutagenic, accumulating in living organisms and blocking biological activities. Nickel and chromium are examples of metals that, in excess, can cause serious health problems. Given the technical and economic infeasibility of conventional methods for treating large volumes of effluents with low concentrations of metals, biosorption emerges as an efficient and economically viable alternative. This technique uses biomass as an adsorbent, with chicken litter being a promising option due to its low cost and high removal capacity. Thus, the objective of this research was to study the potential use of chicken litter in the removal of the heavy metals chromium and nickel from wastewater. The study was conducted at the Chemical Research and Analysis Laboratory of the Federal Institute of Goias - Urutaí Campus, using samples of ground chicken litter. The characteristics of chicken litter, the amount of adsorbed ions, and the removal efficiency at different pH values were evaluated, and the data were fitted to the Langmuir and Freundlich isotherm models. The results indicated that both models adequately describe the adsorption, with the Freundlich model showing a better fit. The maximum adsorption capacity was higher for nickel compared to chromium, following the affinity sequence Ni > Cr. It is concluded that ground chicken litter has great potential for the removal of metallic ions in wastewater treatment systems, showing superior effectiveness to other natural biosorbents and being an economical alternative.

Título: EFEITO DE REGULADORES DE CRESCIMENTO SOBRE A ARQUITETURA DE PLANTAS E O RENDIMENTO DE SOJA Autor(es): Mendes, Diego Rodrigues Primeiro Orientador: Pereira, Alexandre Igor Azevedo Abstract: Growth regulators have the potential to modulate soybean architecture and productivity, but their effects are complex and strongly dependent on interactions among the plant, the product, and the environment. This study comparatively evaluated eight regulators using a multivariate approach capable of integrating morphological, reproductive, and yield-related traits of soybean grown in the Brazilian Cerrado. The experiment was conducted in a randomized complete block design with four replications, with applications at V4, and ten agronomic variables were assessed, including plant architecture, pod classes, and yield. Although ANOVA using mixed models did not detect isolated statistical differences for most variables (p > 0.05), treatment-specific correlations revealed contrasting physiological patterns. Cluster analyses and the Smith–Hazel index proved highly informative, allowing the discrimination of three performance groups: recommended regulators (Stimulate, PR136, and Check), characterized by more balanced responses; intermediate regulators (StoppingGo and MaxCel); and non-recommended regulators (StartStop, Equaliza, and Biozyme), which showed inferior agronomic performance. Thus, even without robust univariate effects, the multivariate approach demonstrated a high capacity to distinguish the agronomic merit of the products, reinforcing that integrated analyses are essential to guide precise recommendations in soybean management. Further research should be conducted to confirm and expand these findings under different cultivation and management conditions. Editor: Instituto Federal Goiano Tipo: Trabalho de Conclusão de Curso
