This study aims to determine the effectiveness of the kepok banana peel (Musa paradisiaca var. bluggoe L) as a liquid organic fertilizer on the growth of Pak Choy (Brassica rapa L). This research was conducted at the Green House PT. Floraterusbersemi, in East Jakarta from March–July 2022. The research method used is an experimental method with the research design using a Completely Randomized Design (CRD). This research was conducted by giving 6 treatments and 5 repetitions, where there were three parameters used, namely plant height, number of leaves, and plant wet weight. The treatment in question was P0 as (control) without giving kepok banana peel liquid organic fertilizer P1 = 10 ml, P2 = 25 ml, P3 = 50 ml, P4 = 75 ml, P5 = 100 ml kepok banana peel liquid organic fertilizer.

Apis dorsata Binghami honeycomb contains secondary metabolites that have antidiabetic potential, including inhibiting the action of the α-amylase enzyme. The purpose of this study was to determine the in vitro antidiabetic potential of Apis dorsata binghami nest extract. This study uses a descriptive research method where the research data are obtained through laboratory experiments. Honeycomb extraction using maceration method. Analysis of total flavonoid content using UV-Vis spectrophotometric method. Antidiabetic potency test using -amylase enzyme inhibition method. The results of the extraction study showed that the % yield of the extract was 11.82% with a brownish yellow color. Analysis of the total flavonoid content showed the results of 3.33 mgQE/g. The inhibitory activity of the -amylase enzyme, the IC50 value of the extract obtained was 158.48±7.42 g/mL, the acarbose value was 165.96±7.08 g/mL. These results indicate that the extract of A.dorsata Binghami nest has hyperglycemic activity by inhibiting complex carbohydrate hydrolyzing enzymes such as inhibition of the -amylase enzyme which is better than acarbose because the IC50 value of the extract is smaller. If the IC50 value is smaller then the enzyme inhibition is stronger. For further research, it is recommended to use a more specific enzyme, namely the -glucosidase enzyme.","PeriodicalId":422054,"journal":{"name":"JURNAL PEMBELAJARAN DAN BIOLOGI NUKLEUS","volume":"256 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133338880","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}
