Para que se tenham frutos de alta qualidade, há necessidade da adoção de inúmeras técnicas culturais e dentre estas, está o ensacamento dos cachos, que, apesar de onerar o custo de produção, é uma prática que vem sendo recomendada em plantios comerciais de bananeira que produzem frutos com melhor qualidade. Diante do exposto, o presente trabalho teve como objetivo avaliar a influência de tipos de materiais para ensacamento de cachos de banana, no desenvolvimento e qualidade dos frutos de bananeira „BRS Platina‟. O experimento foi realizado na Fazenda Experimental Lageado, pertencente à UNESP, campus de Botucatu. O delineamento estatístico experimental utilizado foi em blocos casualizados, composto por seis tratamentos, quatro blocos e quatro plantas por parcela, sendo os tratamentos: T1 – testemunha (sem ensacamento); T2 – Saco de polipropileno (TNT), cor preta + Papel kraft; T3 – Saco de polietileno, cor preta + Papel kraft; T4 – Papel kraft; T5 – Saco de polipropileno (TNT), cor branca; T6 – Saco de polietileno, cor branca. Foram feitas avaliações de características fenológicas, desempenho agronômico produtivo, qualidade pós-colheita dos frutos e análise econômica. Os resultados foram avaliados estatisticamente, mediante análise de variância com aplicação do teste F à 5% de probabilidade (p<0,05) e as médias comparadas pelo teste Scott-Knott ao nível de 5% de probabilidade. Concluiu-se que o ensacamento é eficaz no controle de tripes da erupção e na redução de defeitos ou injúrias, não afetando a produção, além de promover poucas alterações nas características físicas e químicas dos frutos. O tratamento com ensacamento utilizando polietileno branco apresentou melhor custo-benefício, com maior produtividade anual média e menor custo anual médio de produção. / Brazil is the fourth largest producer of banana in the world, however, it presents difficulties in expressive participation in the international market, which in turn is directly related to the factors of traditional production patterns, with low investments of capital and technology in the majority of producing regions in the country. In order to have high quality fruits, there is a need to adopt numerous cultural techniques, among which is the bagging of bunches, which, despite costing the production, is a practice that has been recommended in commercial banana plantations that produce better quality fruits. In view of the above, the present work had the objective of evaluating the influence of types of materials for banana bagging on the development and quality of 'BRS Platina' banana fruits. The experiment was carried out at Experimental Farm Lageado, belonging to UNESP, Botucatu campus. The experimental design was a randomized block design, consisting of six treatments, four blocks and four plants per plot. The treatments were: T1 - control (without bagging); T2 - Polypropylene bag (TNT), black color + Kraft paper; T3 - Polyethylene bag, black color + Kraft paper; T4 - Kraft paper; T5 - Polypropylene bag (TNT), white color; T6 - Polyethylene bag, white color. Evaluations of phenological characteristics, productive agronomic performance, post-harvest quality of fruits and economic analysis were performed. The results were statistically evaluated by analysis of variance with application of the F test at 5% probability (p <0.05) and the means compared by the Scott-Knott test at the 5% probability level. It was concluded that the bagging is effective in the control of thrips of the eruption and in the reduction of defects or injuries, not affecting the production, besides promoting few changes in the physical and chemical characteristics of the fruits. The treatment with bagging using white polyethylene presented better cost-benefit, with higher average annual productivity and lower annual average cost of production.

Drywall board-based structures, a competent and cost-effective method of providing flexible partitioning assemblies in commercial and residential houses, are now widely used as walls or ceilings. However, the gypsum-based drywall that has been used in construction is not water-resistant and can create problems such as mold growth and structural defects. The aim of this study is 1) to develop a new sandwich panel with better physical and mechanical properties using locally sourced materials 2) to investigate the long-term hygrothermal performance of the new sandwich panel through using a numerical simulation. The sandwich panel is composed of two different thicknesses of kraft-paper honeycomb core bonded to two cementitious panels with silicone-based adhesive. The experimental results show that the sandwich panel with a thicker core has lower thermal conductivity and higher flexural strength compared to the gypsum-based drywall. The heat and moisture performance of two wall structures were performed using the WUFI Pro simulation program. The results of the modeling analysis present that wall assembly with gypsum-based drywall has higher water content than multilayer sandwich panel. In addition, the multilayer sandwich panel shows a 4.6% lower annual heat flow compared to the reference wall.

El presente proyecto se basa en la producción y comercialización de fertilizante natural y biodegradable, que sirve como bio-estimulante para las plantas ornamentales, teniendo como valor adicional ser un retenedor de agua de riego durante 20-21 días aplicando una sola vez el producto. Elaborado a base de cáscara de naranja y palta, nuestro negocio va dirigido a habitantes de Lima Moderna correspondientes a los estilos de vida conservador, moderno y sofisticado que posean plantas y/o pequeños jardines pertenecientes a los niveles socioeconómicos (NSE) A, B y C, además de mostrar preocupación por el medio ambiente. El empaque del producto va a ser una bolsa de papel kraft biodegradable con una capacidad 250 gramos. Se realizó una total de entrevistas a 30 personas para validar la existencia del problema encontrado y el interés e intención de uso del producto de nuestros posibles clientes. Además, con fines de hacer este proyecto escalable para el rubro de la agricultura, se contactó a dos expertos en agronomía para validar el producto y algunos aspectos sobre la posible escalabilidad de este. El desarrollo del proyecto se encuentra dividido en dos puntos, los cuales son la validación del plan de negocio y desarrollo del plan de negocio. Para la ejecución del proyecto se requirió una inversión de 21,454 soles, obtenidos a base de capital propio de los accionistas, quienes estiman recuperar dicha inversión en el primer año de operación. La rentabilidad brindada a los accionistas es de 249% lo cual hace nuestro proyecto un negocio rentable. / The present project is based on the production and commercialization of natural and biodegradable fertilizer, which serves as a bio-stimulant for ornamental plants, with the additional value of being a water retainer for 20-21 days by applying the product once. Made with orange and avocado peel, our business is aimed at inhabitants of Modern Lima corresponding to conservative, modern and sophisticated lifestyles that have plants and / or small gardens belonging to socioeconomic levels (NSE) A, B and C, in addition to showing concern for the environment. The product packaging is going to be a biodegradable kraft paper bag with a capacity of 250 grams. A total of interviews were conducted with 30 people to validate the existence of the problem encountered and the interest and intention of using the product of our potential customers. In addition, in order to make this project scalable for the field of agriculture, two agronomy experts were contacted to validate the product and some aspects of its possible scalability.
