There are secondary metabolite compounds in betel nut. The presence of this secondary metabolite content makes the betel nut skin a high potential as a bioreductant to synthesize silver nanoparticles as an antibacterial. The process of synthesizing silver nanoparticles is carried out with the addition of a stabilizer in the form of Polyvinyl alcohol (PVA). The analysis results obtained using the UV-Vis instrument have wavelengths with variations in the addition of 1%, 3% and 5% PVA, respectively, are 448 nm, 456 nm and 460 nm. In the results of the analysis using XRD, the value of 2θ is silver nanoparticles (PVA 1%): 38,020; 43,930 ; 64,320 ; 77,270. silver nanoparticles (PVA 3%): 38,230; 44,270 ; 64,610 ; 77,500. And silver nanoparticles (PVA 5%) are 38,100 ; 44,240 ; 64,460 ; 77,370. For analysis using SEM, the particle size obtained with the help of the Imegej and OriginLab 8.5 applications, namely at AgNPS + PVA 1% is 28 nm - 31 nm. Agnps + PVA 3% ranged from 26 nm – 29 nm. And Agnps + PVA 5% has a size of 19 nm – 22 nm. For the results of FTIR data, the specific absorption peaks of Ag nanoparticles are located at frequencies of 412.23 cm-1, 453.57 cm-1, and 476.84 cm-1. Then in the antibacterial test, silver nanoparticles were used with the addition of 5% PVA. The size of the clear zone obtained in the test for E. coli bacteria is 11.2 mm and for S. Aureus it is 13 mm.","PeriodicalId":495111,"journal":{"name":"Indonesian Journal of Chemical Analysis","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136309424","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}
