Limbah tanpa perlakuan khusus dibuang ke lingkungan. Sehingga metode pertukaran ion dapat mengurangi pencemaran lingkungan akibat limbah industri batik. Penelitian ini bertujuan untuk mengetahui pengaruh resin dalam menurunkan kandungan ion kromium pada limbah cair industri batik dengan menggunakan metode pertukaran ion. Yaitu dengan menggunakan dua kondisi operasi yang divariasikan yaitu berat resin (40, 60, 80, 100, dan 120 gram) dan kecepatan pengadukan (150, 175, 200, 225, dan 250 rpm). Ion kromium yang bermuatan positif akan bertukar dengan H +ion yang ditemukan dalam resin dowex. Sehingga kandungan krom pada limbah cair batik dapat dikurangi. Hasil tersebut diperoleh dari kecepatan pengadukan dan berat resin yang digunakan. Penurunan kandungan ion chromium tertinggi terjadi pada kecepatan pengaduk 250 rpm dengan berat resin 120 gram sebesar 97,86%.","PeriodicalId":32236,"journal":{"name":"Konversi","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90874421","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 implementing the 3R TPS planning, data on waste generation, volume of waste generation and composition of waste generated by the community are needed every day. The calculation method used in this plan refers to SNI 19-3964-1994. From the data obtained, waste generation is 0.36 kg/person/day and waste volume is 132.93 kg/m3.

The planned waste management and processing at TPS 3R Sedati District is divided into 2, namely organic waste processed into compost and non-organic waste sold to collectors, and for residual waste that is not processed it is transported to landfill. The area of land required for planning TPS 3R is 1751.5 m2 which is located in Tambak Cemandi Village.

This study aims to determine the effect of variation in the concentration of Averrhoa bilimbi extract on the characteristics of rubber clone IRR 118 as well as the advantages and disadvantages of using the extract as natural coagulant. The rubber clone used was IRR 118 with various Averrhoa bilimbi etracts of 20%, 40%, 60%, 80% and 100% and 2% synthetic chemical coagulant formic acid as comparison.

The processing process that can be applied is by converting it into compost with an aerobic process with a windrow system. The purpose of this study was to evaluate the composting system and the results of existing waste processing. This research was conducted by direct observation and secondary data collection from the local management inventory. The composition of biodegradable waste in Jambi City consists of 47.4% food waste and 2.1% garden waste. However, the application of food waste is quite difficult to handle because of its characteristics, therefore garden waste is a priority for reduction by the government. The results of monitoring for one month in a row mean that the waste entering the compost facility is 4086 kg/day. The percentage of waste reduction from composting activities in total can be 0.986% of the total waste generation of Jambi City, or 45.426% of the total waste generation of Jambi City's gardens.

One of the most effective method to reduce the levels of heavy metals mercury (Hg2+) in liquid waste is adsorption. Rice husk ash is highly potential to adsorb heavy metals in water because it is a porous material with a high silica content. Therefore, rice husk ash can be used as an adsorbent for heavy metals in liquid waste. The purpose of this study was to determine the level of mercury (Hg2+) that can be adsorbed from the column adsorption process using adsorbent of rice husk ash and to determine the optimum mass of rice husk ash as an adsorbent. The research was conducted using a series of simple adsorption column tools with a circulation time of 120 minutes. While the independent variables were adsorbent particle size of 50, 100, and 200 mesh. Measurement of mercury (Hg2+) levels was carried out on samples before and after treatment with Atomic Absorption Spectrophotometer (AAS). The results showed a significant decrease in Hg2+ levels with the optimum adsorbent particle size of 200 mesh.
