Generally, POME processing in Indonesia uses an open pond system. It is less efficient because it requires large areas and causing greenhouse gas effects. This research aims to improve the POME processing, three methods were studied; bioremediation using enrich indigent lypholitics bacteria (Bacillus toyonensis and Stenotrophomonas rhizophila.), electrocoagulation system, and combination of those methods. The parameters were measured were oil and fat contents, COD, pH, TSS, TDS, Fe and Cu metals. In the electrocoagulation method, the electrodes were used iron electrodes with a variation of electrical voltage 1.5, 3, 4.5 and 6 V. The bioremediation using indigent bacteria results in the removal of oil and fat -74.62%, COD -52.44%, TSS -43.11% and pH 6.38 at the incubation time for 6 days, TDS 21.42%, Fe -5.3% and Cu -64.70%. The electrocoagulation methods results oil and fat removal were -93.27%, COD was -85.71%, TDS -39%, TSS -84%, Cu -46%, Fe +92.35%, and pH 11.39 at a voltage of 6 V for 6 h. The combination of the two methods can reduce oil and fat levels by -87.39%, COD -56.70%, TDS -0.42%, TSS +15.88%, Cu -23.33%, Fe +93.74% and pH 8.82.

One of the alternative energy sources that can be evolved is bioethanol due to the high amount of oxygen component in it hence it can be combustible and eco-friendly. Mesocarp is farming and trading waste of Cocos Nucifera (Coconut) that contains 40% lignin, 44,4% cellulose, and 15% hemicellulose. Delignification is a process of removing lignin from the materials thus it can produce the high purity of cellulose. As long as this, there were numerous studies that researched about lignocellulose biomass, however the least studies researched the impact of using delignification. Thereby, this study was done for figuring out the impact of HCl concentration and length of time to the decreased lignin content and the quality of bioethanol. The points of impacts that being focused on were 1M, 2M, and 3M HCl concentration, whereas the points of length of time impacts were about 60 minutes, 90 minutes, 120 minutes, 150 minutes, and 180 minutes. The decreased lignin content that was obtained is about 18,5% and the finest bioethanol is 97,38 %, 15oC for flash point, 3,8402 cPs for viscosity, and 0,8252 gr/cm3 for density from delignification using 3M HCl for about 150 minutes. Greater HCl concentration to delignification, greater quality of bioethanol that is produced, therefore can be applied to alternative fuel oils for vehicle.","PeriodicalId":31600,"journal":{"name":"IJFAC Indonesian Journal of Fundamental and Applied Chemistry","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77561556","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 research was carried out from January to April 2022 at the Chemical Engineering Laboratory of the Sriwijaya Polytechnic. The sampling location for this research is Kelekar River, Karang Raja Village, East Prabumulih. The main tools and materials are a series of water filters (microfiltration–adsorption–ceramic membrane) and river water. The analysis results show that a series of microfiltration-adsorption-ceramic membrane integrated process water treatment equipment can be used to treat river water into clean water. Based on the analysis of river water quality parameters, such as BOD5, iron (Fe), manganese (Mn), nitrate (NO3-), ammonia (NH3-N), and total coliform bacteria after water treatment were within environmental quality standards. Meanwhile, COD and nitrite (NO2-) were still not meeting the environmental quality standards set by Government Regulation of Republic Indonesia No. 22 of 2021 concerning the implementation of environmental protection and management.","PeriodicalId":31600,"journal":{"name":"IJFAC Indonesian Journal of Fundamental and Applied Chemistry","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82336858","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 was confirmed via scanning electron microscopy (SEM), which revealed the presence of a unique form with a honeycomb-like pattern. Meanwhile, the materials largely consisted of carbon and oxygen elements, as was revealed by the energy dispersive X-ray (EDX) analysis, while the XRD analysis indicated that the nest was composed of amorphous materials of cellulose and lignin. Finally, the (FTIR) spectroscopy analysis revealed the presence of a number of peaks, which indicated that the material also consisted of a mixture of cellulose, hemicellulose, and lignin materials.

This study aims to characterize coal gasification char using a prototype underground coal gasification (UCG) and the addition of coconut shell charcoal biomass as a raw material for making biobriquettes. By using coal as raw material from the Muara Tiga Besar Mine of PT Bukit Asam, five kinds of coal samples from different layers were obtained, which from the characterization results, both coal and char, did not have too significant deviations so that the research variables could be ignored. The results of the characterization of char from coal gasification results compared to the initial sample of coal showed an increase in calorific value, a decrease in sulfur content and a significant decrease in water content, so it can be concluded that char from coal gasification has good potential as a raw material for biobriquettes.
