The method used is alkalimetry to determine the acid value and acidimetry for the determination of the Saponification Value. The results obtained were Acid Value 0.92 ppm - 1.02 ppm which was following the PT X standard, max 1ppm. The Saponification Value the results obtained were 132 ppm - 142 ppm which was following the PT X standard, min 130 ppm. This indicates that the resulting wax ester can be used for the preparation of fatty alcohols in sections 111-113.","PeriodicalId":174114,"journal":{"name":"REACTOR: Journal of Research on Chemistry and Engineering","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133237180","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}

To support the development of industries in Indonesia in order to be able to compete with similar industries from abroad, it is very important to pay attention to the quality of the paper produced. One way to determine the quality of the pulp & paper is by knowing the chemical composition and area where the wood grows. Important chemical compositions that can support the strength of wood and paper quality include cellulose and lignin. Therefore, this study was conducted to compare the levels of cellulose and lignin contained in Acacia crassicarpa wood from wetlands and Acacia mangium from dry land which is processed into pulp & paper with good quality. Determination of cellulose and lignin content in wood was carried out using the gravimetric method. Test results on Acacia crassicarpa wood species from wetlands obtained cellulose content of 55.48% and lignin 24.13%, while in Acacia mangium wood from dry land obtained cellulose content of 51.46% and lignin 27.66%. According to company standards that levels of cellulose and lignin in two different fields are obtained according to the standards set by the company. So for the results of testing Acacia crassicarpa wood from wetlands have the highest levels of cellulose with low levels of lignin","PeriodicalId":174114,"journal":{"name":"REACTOR: Journal of Research on Chemistry and Engineering","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114540756","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}
