Supercapacitors provide very high power density values, long repetition cycles and have a higher repetition efficiency compared to batteries. This study aims to design a supercapacitor with a material of 0.905 gram graphene powder, 2 gram activated carbon, epoxy resin (3 spoonfuls of spatula), Phosphoric Acid (H 3 PO 4 ) electrolyte solution, and aluminum plate with a size of 8 cm x 8 cm, 6 cm x 6 cm, and 5 cm x 5 cm as collector media. The research was carried out in four stages, namely mixing graphene powder and epoxy resin, coating graphene-epoxy resin powder on both plates, sowing activated carbon on the surface of the plate, and combining the two plates into one supercapacitor section. The test results show that with the charging-discharging method, the size of 8 cm x 8 cm which is carried out charging for 3 minutes can store a voltage of 1.65 Volt, on the size of 6 cm x 6 cm done charging for 3 minutes can store a voltage of 1.44 Volt, and at a size of 5 cm x 5 cm by charging for 3 minutes can store a voltage of 1.05 Volt. So it can be proven that the cross-sectional area of a supercapacitor greatly influences the value of the stored voltage.","PeriodicalId":257157,"journal":{"name":"Proceedings of the 1st International MIPAnet Conference on Science and Mathematics","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127740948","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 making of goat milk kefir was used 3% kefir granule (HK) and 5% kefir granule (KK) from total volume of goat milk. As well as coconut milk kefir was used 3% kefir granule (HS) and 5% kefir granule (KS) from total volume of coconut milk. The kefir beverage, conducted quality analysis with result pH 4.2% – 4.6%, water content 89.5% (HK), 89.1% (KK), 79.2% (HS) and 78.9% (KS). Protein content 3.3% (HK), 3.1% (KK), 1.7% (HS) and 1.6% (KS), fat content 3.58% (HK), 15.2% (HS), 3.61% (KK), dan 15.8% (KS), ash content 0.79% (HK), 0.54% (HS), 0.81% (KK) and 0.9% (KS). Antibacterial test was conducted by observing the clear zone for 48 hours. Using Escherichia coli and Staphylococcus aureus as the test bacteria, resulted that sample HK showed the highest level of resistance compare to other samples. Total plate count of LAB showed that sample KK has the highest number of LAB counts for 1.7 x 10 8 . Morphology characterization of those colony are round shape, convex elevation, off-white and also gram positive bacteria with six isolate rod shape cell, and two isolate coccus shape cell. The catalase and oxidase test showed that all isolate are negative catalase and negative oxidase.","PeriodicalId":257157,"journal":{"name":"Proceedings of the 1st International MIPAnet Conference on Science and Mathematics","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115436192","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}

Method in this research is mixed-method that used side by side approach. The first, quantitative will be used and the second, the researcher could observe and interview. The effect of parental style is not seen in students’ asking levels evidenced by the results of the multinomial logistic regression test a-sig = 0.207. Qualitative research results are presented after quantitative results. 81.25 % of students receive authoritarian parenting, and 18.25 % authoritative. The temporary conclusion is that the habit of asking questions is formed from childhood. Precisely, the authoritarian parenting styles received by almost all respondents made them reluctant to ask questions in class. Because when they were little they were only asked to obey orders without commenting anything. However, this research had a weaknesses, the scale should be given with each parenting pattern so that maximum results are obtained, and observations in class discussions are conducted in the long term and in several classes so that the observations are more accurate.","PeriodicalId":257157,"journal":{"name":"Proceedings of the 1st International MIPAnet Conference on Science and Mathematics","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114574874","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}
