The present study was to determine the secondary metabolites contained in red ginger rhizome plants and antibacterial activity against Staphylococcus aureus and Escherichia coli bacteria. A total of 483.2 grams of red ginger powder was extracted by maceration method obtained from ethyl acetate extract 15.85 g. Antibacterial activity of red ginger extract against S. aureus and E. coli using microdilution method showed that ethyl acetate extract could inhibit S. aureus growth by MIC (Minimum Inhibitory Concentration) 6.3% and MBC (Minimum Bactericidal Concentration) 25% and extract Ethyl acetate red ginger rhizome can Minimum MIC (E. Inhibition Concentration) E. coli with a minimum inhibitory concentration of 25% and MBC (Minimum Bactericidal Concentration) 50%. The results showed that the red ginger rhizome ethyl acetate extract was the most influential and had more potential to inhibit the growth of Gram positive bacteria compared to inhibition of Gram negative.","PeriodicalId":17768,"journal":{"name":"Jurnal Kartika Kimia","volume":"174 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83333614","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}

High silica content in rice husks can be used as an alternative source of potential silica for the synthesis of calcium silicate as a base material of Trioxide Aggregate mineral composites in tooth biocement. In this study, calcium silicate was obtained through two stages of the process, namely silica isolation from rice husk ash by sol-gel method, and reacting between silica and calcium oxide. Silica and calcium oxide are reacted to the mole ratio between silica to calcium oxide of 7:3, 6:4, 4:6, and 3:7. The isolated silica is characterized by the distribution of the size and composition of each element with Particle Size Analyzer (PSA) and EDS. The formation of calcium silicate and its size distribution from the synthesis stage is determined by XRD and PSA. The result showed that silica isolation from rice husk ash with sol-gel method obtained silica with content and particle size of 71.6% and 52.82 mm. While the optimum condition of calcium silicate synthesis was achieved at the mole ratio of silica to calcium oxide by 4:6. In the mole ratios obtained calcium silicate type b-dicalcium silicate with an average particle size of 102.2 mm.","PeriodicalId":17768,"journal":{"name":"Jurnal Kartika Kimia","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75072961","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}
