Tahap ke dua memformulasikan pengomplek NaOH (35%, 30%, 25%, 20%, 15%) dan  Al 2 (SO 4 ) 3 (35%, 30%, 25%, 20%, 15%) untuk setiap 35% ekstrak gambir dalam etanol. Analisis terhadap tinta stempel adalah penentuan gugus fungsi, distribusi dan ukuran partikel. Hasil penelitian menunjukkan bahwa tinta stempel dengan pengomplek 15% NaOH yang terbaik, karena nilai ukuran partikel dan polydispersity index (pdi) paling rendah dari semua perlakuan, sehingga tinta yang didapatkan tidak menggumpal.","PeriodicalId":31936,"journal":{"name":"JLI Jurnal Litbang Industri","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77752848","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}
