This study aims to determine the effect of Jatropha Curcas L. leaf extract on the freshness quality of Layang Fish (Decapterus sp.) At room temperature storage. The research consisted of two stages, namely preliminary research and main research. Preliminary research is determining the concentration of castor leaves. The main research is the concentration of Jatropha leaves used, which is 16% with a storage time of 10 hours, 14 hours, 18 hours and 22 hours. The test was carried out organoleptically (hedonic quality) and TPC. This design uses kruskall wallis for organoleptic data (hedonic quality), CRD to obtain TPC results. Organoleptic data and TPC that had a significant effect were tested by Duncan's continued test. The results showed that the fresh fly fish preserved with 16% castor leaf extract was able to maintain the quality of the fresh fly fish for 14 hours of storage. The chemical test results showed that the fresh fly fish with 16% castor leaf extract in 14 hours of storage, the microbiological quality obtained ALT value of 5.03 CFU / g, this fulfills SNI 2729.2013 concerning fresh fish.

E-mail: [email protected] .     1 RESUMO   O pinhão manso é uma oleaginosa com alto potencial para produção de biodiesel e biolubrificantes, porém existem poucos trabalhos abordando o efeito da irrigação e demandas nutricionais sobre a qualidade e composição do óleo. Portanto, o objetivo deste trabalho foi avaliar o efeito da adubação potássica e da irrigação sobre a composição do óleo de pinhão manso. O experimento foi desenvolvido na área experimental da Escola de Agronomia da Universidade Federal de Goiás, Goiânia, Goiás. Os tratamentos consistiram de quatro doses de adubação potássica, sendo: 40, 80, 120, e 160 kg ha-1, e quatro lâminas de irrigação: 0% (sem irrigação), 40%, 80% e 120% da evaporação do tanque Classe A (ECA). O delineamento experimental foi em blocos casualizados, com 4 repetições, analisado no esquema de parcelas subdivididas. Para extração de óleo das sementes utilizou-se o método mecânico por prensagem e para obtenção da composição de óleo utilizou-se a cromatografia gasosa. Os tratamentos de adubação e irrigação promoveram alterações na qualidade do óleo de sementes de pinhão manso. Plantas adubadas com 120 kg ha-1 de K2O e irrigadas com a lâmina de irrigação de 80% da ECA obtém os melhores resultados.   Palavras-chave: biodiesel, lâminas de irrigação, nutrição de plantas, Jatropha curcas.     EVANGELISTA, A.

OIL QUALITY OF JATROPHA TREE CULTIVATED UNDER DIFFERENT MANAGEMENTS OF IRRIGATION AND POTASSIUM FERTILIZATION     2 ABSTRACT   Jatropha is an oilseed with high potential for biodiesel and biofuel production. However, studies are scarce about the effect of water and nutritional requirement in the oil quality and composition. Therefore, the objective of this work was to evaluate the effect of potassium fertilization and irrigation on the composition of jatropha oil. The treatments consisted of four potassium fertilization levels: 40, 80, 120, and 160 kg ha-1, and four irrigation levels: 0% (without irrigation), 40%, 80% and 120% of Class A pan evaporation (ECA). The experimental was design in randomized blocks with subdivided plots and four replicates. The mechanical method by pressing was used to extract oil from the seeds, using gas chromatography to obtain the oil composition. Fertilization and irrigation treatments promoted changes in the quality of jatropha seeds oil. Plants fertilized with 120 kg ha-1 of K2O and with  irrigation level of 80% of ECA show the best results.   Keywords: biodiesel, irrigation management, plant nutrition, Jatropha curcas.
