The breadfruit starch is tied with trisodium trimetaposphate to produce pospat starch. The highest degree of substitution was obtained in variation of trisodium weight of trimetafosfat 3%, that is 0,0633. PCL / Starch Biocomposite was prepared by mixing method between PCL in chloroform solvent with modified 3% sodium starch then printed at 75˚C since 10 minutes. Mechanical properties, functional group, and morphological of PCL/Modified breadfruit starch biocomposite was analyzed. The result of evaluation showed an optimal tensile test value of 90%: 10% with tensile strenght of 7,4287 MPa and Modulus Young’s of 27,852 MPa. The functional group analysis of phosphate starch showed asymmetric P-O-C group at wave number 1018,41 cm -1 . Analysis with FT-IR from PCL/Modified Breadfruit Starch Biocomposite showed of physical interaction occurred between PCL and modified breadfruit starch. Morphological analysis using SEM showed smooth and homogeneous surface of biocomposite.","PeriodicalId":20533,"journal":{"name":"Proceedings of the 1st International Conference on Chemical Science and Technology Innovation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74337557","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}

In this work, cotton cellulose (CCell) fibres was modified in a laboratory scale reflux-reactor for 2 hours in toluene (TL) as solvent with addition of maleic anhydride (MA). TL solution of antimicrobial compound of AETAC and ammoniumpersulphate (NH4)2S2O8) as initiator was added dropwise and the reflux was further continued for 2 hours. The reaction mixture with optimum weight ratio (CCell/MA/AETAC: 100/20/20) was then cooled down, filtered and wash thoroughly using distilled water and dried in oven vacum to constant weight at 80C. The AETAC/MA-modified Cellulose (AETAC/MA-g-CCell) was then characterised using infrared spectroscopy (FTIR) for chemical structure identification of the reaction products. Antimicrobial properties of the modified cellulose was tested using: Aspergillus niger and Staphylococcus aureus. Results of FTIR spectra of the AETAC/MA-g-CCell after exhaustive Soxhlet extraction in toluene still showed stable absorption peak of AETAC/MA carbonyl group (>C=O) at 1736 cm and dissapearance of bond absorption peak of acryloyl group (>C=C<) at 1470 cm. The AETAC/MA-modified cotton cellulose showed marginal antimicrobial activity against Aspergillus niger, however the modified cellulose showed excellent antimicrobial activity against Staphylococcus aureus.","PeriodicalId":20533,"journal":{"name":"Proceedings of the 1st International Conference on Chemical Science and Technology Innovation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90174910","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}

This review papers of SSCM is done from period 2018-2019. From the results of the review it can be seen the trends of the sustainable supply chain model that could be used as a reference for future research. This study discusses the concepts that have been applied to previous studies of sustainable supply chains involving organizations, based on assessment and study of literature on supply chains. In this journal there are several parts, namely the first part which contains the research background. The second section contains a literature review that is the literature that supports research and about the results of a review of several research journals about SSCM from 2018 and 2019. The third section contains the methods used in the research, which contain the stages of research. The fourth part contains a summary of research, the results of research on SSCM. The manufacturing industry is always related to chemical processes at the stages of the production process. This also always influences the environment. That is why the sustainable topic becomes an important thing to study and to find the solutions.","PeriodicalId":20533,"journal":{"name":"Proceedings of the 1st International Conference on Chemical Science and Technology Innovation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75343167","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}

This plant originates from Australia, which is one of the most popular eucalyptus trees that grows in almost all of Australia, and is now found to grow in almost all tropical regions of the world including Indonesia. Content Analysis and determination of sineol Content in Eucalyptus citriodora leaf essential oil from PT. Toba Pulp Lestari Tbk has been carried out by the GCMS method. Eucalyptus leaves have been used for medicine, industry and perfume as well as Eucalyptus oil. The purpose of this study was to determine the compound content and levels of cineol in Eucalyptus citriodora leaves. The abundance of sineol levels 55-65% can be used as perfume, medicines and Eucalyptus oil. Stahl distillation was developed to produce The Eucalyptus oil. There are eleven compounds in Eucalyptus citriodora leaves, including α-Pinene, 1-Limone, 1.5 Cyclooctadiene, 1.8 Sineol, 1-P-Menthen-8-YL-Acetate, 3- Cycloheksane, 1-Methanol, α-Terpinyl Acetate, Phenol, Butylhidroxytoluena, Trans-Methyl-dihydrojasmonate, ISO - Cytronellate, ISO - Propyl Myristat, Propyltetradekanoate, Octadecanoic Acid. The mximum abundance is 1,8-cineol (60.29% v/v).
