The quality of seeds will determine the productivity and quality of seeds. Storage treatment is one way that can be done to maintain seeds until the seeds are planted, but storage treatment that is too long will cause seed deterioration or seed viability to decrease. The decline in seed quality caused by keeping in open spaces storage causes fluctuations in temperature and humidity due to direct interaction with the environment. Efforts to control factors that can affect the rate of seed deterioration can be executed, among others, by using an impermeable storage container. Impermeable storage containers do not support the exchange of air from the environment to the inside of the storage container. The purpose of this study was to determine which type of impermeable storage container is best for the quality of rice seeds. The research has been at the Laboratory of Center for Supervision and Certification of Food Crops and Horticulture Seeds, South Kalimantan Province, Banjarbaru City and used a one-factor CRD with w0 (+) (cans), w0 (-) (plastic sack), w1 (glass jars), w2 (plastic jars) and w3 (aluminum foil). The results of the study indicated that the use of impermeable storage containers had a significant effect on moisture content, germination, and maximum growth potential of rice seeds. The use of the best impermeable storage container for the moisture content of rice seeds in the storage period of 45 days after storage (das) was found in the w3 treatment (aluminum foil) of 11.63%, while the parameter of germination in the 15 das was 63.83%, the maximum growth potential in the storage period of 45 and 90 das was found in the w1 treatment (glass jar) of 73.50% and w0 (+) (cans) of 70.69%.","PeriodicalId":311412,"journal":{"name":"Gontor AGROTECH Science Journal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123775238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This plastic waste is in the form of single-use plastic bags, plastic cups, plastic bottles, plastic straws, styrofoam from restaurants, packaged drinks, snack packaging, and so on. Therefore, efforts are made to synthesize the raw materials for making plastics or polymers that can be properly degraded by soil microorganisms called biodegradable plastics. Starch is a potential raw material for making bioplastics. However, the use of starch as a material for making bioplastics is considered fragile so it needs a natural reinforcement, namely a coconut fiber powder. This study aims to see the effect of adding coconut fiber powder to bioplastic glass. Bioplastic cups are made from cassava starch and glycerol with the addition of coconut fiber powder as a reinforcement. The research methode used a completelyrandomized design using 1 factor, namely the addition of coconut fiber powder with 4 levels of treatment. The results showed that, in testing the solubility of bioplastic glass experienced the greatest weight reduction in treatment P3 with a value of 0.85%, in testing the resistance to hot water, bioplastic glass experienced the greatest weight loss in treatment P0 with the weight loss value at 80 ° C was 0.55 % and at a temperature of 100 ° C of 1.66%, in the biodegredable test, the bioplastic glass experienced the greatest weight loss in treatment P1 with a value of 0.60%.","PeriodicalId":311412,"journal":{"name":"Gontor AGROTECH Science Journal","volume":"2017 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132928520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
