Ganitri seeds have not been fully utilized. Indonesian ganitri seeds are not widely known for their chemical content, so they are only used as jewelry and trade. This research was conducted to determine the potential of ganitri seeds as biodiesel feedstock. The research method used is the method of sochletation and maceration. The results showed that the effective content of ganitri seed oil was obtained by the sochletation method. The level of FFA (Free Fatty Acid) of ganitri seed oil is 2.8%, so preliminary action needs to be taken, namely the esterification process in the process of making biodiesel. From the results of the research conducted, ganitri seed oil can be used as raw material for making biodiesel but is less effective for mass production.","PeriodicalId":368329,"journal":{"name":"VIGOR : JURNAL ILMU PERTANIAN TROPIKA DAN SUBTROPIKA","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121852206","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}

The experiment was carried out in Balesari Village, Windusari District, Magelang Regency within six months. The aim is to study the growth patterns of cassava leaf shoots and to collect factual practice about the cultivation of cassava leaf which was not yet widely available. A faktorial experiment (2x2x3) which was repeated three times in a completely randomized design. This experiment tested the use of black silver plastic mulch, two cassava Rengganis cultivars, and Indung, with three levels of bud cutting intervals 45, 50 and 55 days after planting. Each treatment was repplicated three times. The results of this experiment indicate that the growth of shoots, namely the weight and length of buds formed is strongly influenced by the type of mulch, cultivar and shoot cutting intervals. Shoot shoots that grow with plastic mulch are better and shoot cutting intervals can also improve shoot shoots. While shoot lengths that grow on Rengganis cultivars are longer than Indung cultivars, there are interactions betweenplastic mulch, cultivars and cutting intervals","PeriodicalId":368329,"journal":{"name":"VIGOR : JURNAL ILMU PERTANIAN TROPIKA DAN SUBTROPIKA","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114998617","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}
