The use of dyeing technology in batik making process generates a large amount of wastewater, which can lead a harmful effect to the environment. To date, Batik Sidomulyo SME uses two types of mori cloth material before dyeing process include mori cloth with and without the mordanting process. The mori cloth with mordanting process was soaked in the alum for 24 hours before the grafting process was carried out. The purpose of this study was to analyze the quality of batik wastewater produced based on the characteristics of the treatment of the fabric material before the embedding process was carried out. Wastewater treatment technology uses technology transfer from Mini Wastewater Treatment Plant (WWTP) which utilizes biofilter technology using two treatment compartment including (1) separation of wax content from wastewater and (2) separation of wastewater from toxic and hazardous material waste by mixing with a coagulant. Measurements of pH, BOD, COD, TSS, and oil/fat were carried out before and after the treatment of Mini WWTP. The results showed that the pH of the wastewater generated from the mini WWTP outlet was following the quality standard of 6.86 and the total suspended solids (TSS) value of 90.16 mg/L. Meanwhile, the values of BOD, COD, and oil/fat content have been significantly reduced but still exceeded that of the quality standards, with the value of 90.16, 253.8, and 4.5 mg/L, respectively.","PeriodicalId":422567,"journal":{"name":"Proceedings of the International Conference on Innovation and Technology (ICIT 2021)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126562586","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 non-renewable nature of coal encourages creating alternative fuels, such as briquettes. The abundance of organic material in dairy sludge has potentially becomes briquettes. To improve the quality of the briquettes, it is necessary to add other biomass with high caloric value, such as coal and coconut shell. Dairy sludge and coconut shell will undergo pyrolysis to produce charcoal later mixed with the coal. The formulation was determined using linear programming, with the decision variables consisting of coal (X1), dairy sludge charcoal (X2), coconut shell charcoal (X3), and binder (X4). The purpose of linear programming is to maximize the heating value of the briquettes and obtain proximate characteristics that suit Indonesian National Standard (SNI 01-6235-2000) for wood charcoal briquettes. The charcoal yield from pyrolysis was 44.35% for dairy sludge and 27.8% for coconut shell charcoal. The optimal briquette formulation was 10% coal, 10% dairy sludge charcoal, 75% coconut shell charcoal, and 5% adhesive. The calorific value obtained reached 9247.41 cal/gram. However, the ash content did not meet the SNI 01-6235-2000.","PeriodicalId":422567,"journal":{"name":"Proceedings of the International Conference on Innovation and Technology (ICIT 2021)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122024080","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}
