Imperata cylindrica is a perennial grass which distributed mainly in South Kalimantan, Indonesia. This grass is a noxious weed both in crops and natural areas, causing severe economic and environmental damage. In this work, Imperata cylindrica was used as raw material to produce cellulose. Cellulose was extracted from Imperata cylindrica through the removal of lignin and hemicellulose. The purpose of this study was to synthesize carboxymethyl cellulose (CMC) obtained through alkalization using sodium hydroxide (NaOH) and carboxymethylation reaction using monochloroacetic acid (MCA). Na-CMC is cellulose-derived material which widely uses in many industrial application, such as pharmaceutical excipients, thickener, binder, and emulsifying agent. The carboxymethylation process of cellulose was confirmed by Fourier transform infrared spectroscopy (FTIR) and further characterized by X-ray diffraction (XRD), degree of substitution value, and levels of solubility. Based on the comparison of FTIR spectra, X-ray diffraction, solubility, and degree of substitution, the optimum condition for Na-CMC synthesis was found to be 15% NaOH and the ratio of MCA to cellulose 0.80. In conclusion of the characteristic study, Imperata cylindrica is an excellent potential alternative cellulose in the pharmaceutical industries.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82913380","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}

The analysis is carried out on the seamless structure, which is considered the ideal structure. The experimental Modal Analysis (EMA) method is used to see the characteristics of the dynamic load distribution in wooden ship construction. Simulation is used to find out which part of the construction has the highest stress concentration. Each construction part is grouped into the rigid base construction section (keel, floor, engine bed, and canal) and the elastic hull construction section (frame, hull board, and hull stringers). The simulation results show that in the radial direction of the fiber, with horizontal vibrations, the smallest amplitude occurs in the frame, while the largest occurs in the channel. In vertical vibrations, the smallest amplitude occurs at the keel and the largest in the hull board. In the tangential fiber direction, with horizontal vibrations, the smallest amplitude occurs in the hull board while the largest occurs in the engine bed area. In vertical vibrations, the smallest amplitude occurs at the keel while the largest occurs in the canal and engine bed.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84303874","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 study, a digester reactor will be developed to produce biogas and benefit from the fertilizer produced from the reactor using animal waste. Animal dung is a valuable source of nutrients and renewable energy. However, it is left to decompose in the open without benefiting from it, causing serious environmental problems, but its use as a raw material in the production of biogas will return to the community of many benefits and eliminate environmental problems. Furthermore, most of the energy needs in Oman is met from the fossil fuels and LPG which are non-renewable energy types of sources which may end one day, biogas which is a renewable energy to some extent can replace LPG. Biogas is a colourless, light gas (half the air density) that ignites in the air as a very high-temperature, blue flame that does not pollute the environment. Its thermal capacity is 5513 kcal/m3. Biogas can widely use in different walks of life such as cooking, electricity generation, produce heat, and some agriculture uses. Experiment was conducted in a laboratory scale 6 L bioreactor, to test the effectiveness of horse dung in biogas production. Experiment was done to test a horse dung slurry as an inoculum for the bioreactor with ethanol. The results obtained show that the gas production has increased with respect to the number of days with the highest production of biogas was obtained after the addition of ethanol as a catalyst for decomposition, which amounted to 2095 ml during the last five days.","PeriodicalId":13712,"journal":{"name":"INTERNATIONAL CONFERENCE ON ENERGY AND ENVIRONMENT (ICEE 2021)","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79225966","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}
