Abstract

Kementerian Perindustrian Indonesia menyatakan bahwa produksi kain batik pada tahun 2017 mencapai rata-rata 500 juta meter/tahunnya yang mana dalam proses pembuatannya membutuhkan air sebanyak 25 juta m3/tahun. Dengan jumlah kebutuhan air yang cukup banyak pada proses produksi, industri batik dapat menimbulkan pencemaran air pada sungai. Sumber utama limbah cair industri batik berasal dari sisa kain mori, sisa lilin, sisa air pewarnaan, dan air bilas. Air limbah dari industri batik yang langsung dibuang ke sungai tanpa melalui pengolahan khusus dapat mencemari kualitas air sungai. Sistem Dual Chamber Microbial Fuel Cell (DCMFC) dapat menurunkan kadar pencemar COD dan BOD yang terkandung pada air limbah industri batik serta metode ini juga dapat menghasilkan energi listrik dalam jumlah yang kecil. Tujuan penelitian ini adalah untuk mengkaji pengaruh penambahan lumpur IPLT dan bakteri EM4 terhadap power density yang dihasilkan oleh sistem DCMFC dan mengkaji pengaruh perbedaan pH pada sistem DCMFC terhadap penyisihan parameter COD dan BOD. Pengukuran kuat arus dan tegangan listrik dilakukan setiap 24 jam. Kemudian untuk pengukuran kadar COD, BOD, MLSS, dan berat biofilm setiap 48 jam selama 240 jam pengolahan. Pengaruh variasi penambahan lumpur IPLT dan bakteri EM4 dalam menghasilkan power density didapatkan hasil yang tidak terlalu besar perbedaannya. Hasil ini dikarenakan oleh beberapa faktor antara lain arus listrik, tegangan listrik, pertumbuhan mikroorganisme, dan pH. Dari hasil penelitian, bakteri EM4 lebih baik dalam menghasilkan power density dengan nilai yang dihasilkan sebesar 297,61 mW/m2. Pada variasi penambahan lumpur IPLT nilai power density sebesar 287,26 mW/m2, dan pada reaktor kontrol yang hanya berisi air limbah batik dapat memproduksi nilai power density sebesar 185,99 mW/m2. Pengaruh perbedaan pH pada sistem DCMFC dapat memengaruhi pertumbuhan mikroba, karena semakin banyak mikroba yang hidup semakin banyak juga mikroba yang dapat mendegradasi kadar organik. Dari hasil penelitian, pH 7 merupakan pH optimum pertumbuhan mikroba untuk setiap variasi. Ketika mikroba dari lumpur IPLT dan bakteri EM4 dikondisikan pada pH 7 (optimum) dapat mencapai efisiensi penurunan kadar COD sebesar 33,83% untuk lumpur IPLT dan 40,76% untuk bakteri EM4. Kemudian, untuk efisiensi penurunan kadar BOD lumpur IPLT dan bakteri EM4 sebesar 42,47% dan 48,49%."

"The Indonesian Ministry of Industry stated that batik cloth production in 2017 reached an average of 500 million meters/year, of which the manufacturing process requires 25 million m3/year of water. With the large amount of water required in the production process, the batik industry can cause water pollution in rivers. The main sources of liquid waste from the batik industry come from mori fabric residue, wax residue, residual dyeing water and rinsing water. Wastewater from the batik industry which is directly discharged into rivers without going through special treatment can pollute the quality of river water. The Dual Chamber Microbial Fuel Cell (DCMFC) system can reduce levels of COD and BOD pollutants contained in batik industry wastewater and this method can also produce small amounts of electrical energy. The purpose of this research is to examine the effect of adding IPLT sludge and EM4 bacteria on the power density produced by the DCMFC system and to examine the effect of pH differences in the DCMFC system on the removal of COD and BOD parameters. Measurements of electric current and voltage are carried out every 24 hours. Then the levels of COD, BOD, MLSS, and biofilm weight were measured every 48 hours during 240 hours of processing. The effect of variations in the addition of IPLT sludge and EM4 bacteria in producing power density showed that the results were not that big of a difference. This result is caused by several factors, including electric current, electric voltage, growth of microorganisms, and pH. From the research results, EM4 bacteria are better at producing power density with a resulting value of 297,61 mW/m2. In the variation of adding IPLT sludge, the power density value was 287,26 mW/m2, and in the control reactor which only contained batik wastewater, it could produce a power density value of 185,99 mW/m2. The effect of pH differences in the DCMFC system can influence microbial growth, because the more microbes that live, the more microbes can degrade organic levels. From the research results, pH 7 is the optimum pH for microbial growth for each variation. When microbes from IPLT sludge and EM4 bacteria are conditioned at pH 7 (optimum), COD level reduction efficiency can be achieved by 33,83% for IPLT sludge and 40,76% for EM4 bacteria. Then, the efficiency of reducing the BOD levels of IPLT sludge and EM4 bacteria was 42,47% and 48,49%."
