Abstract

Workshop di PT Pamapersada Nusantara (PAMA) menghasilkan limbah B3 berupa lumpur campuran antara pasir/tanah, air, dan hidrokarbon sebanyak 73 drum/tahun. Limbah tersebut langsung diserahkan ke pihak ketiga untuk dikelola lebih lanjut. Pada metode co-composting polutan organik dapat ditambahkan sebagai ko-substrat. Selama proses pengomposan berlangsung, polutan tersebut dapat mengalami biodegradasi. Oleh karena itu dilakukan penelitian yang terkait dengan penerapan metode co-composting pada proses pengolahan lumpur berminyak. Penelitian ini bertujuan untuk: (1) menentukan efisiensi penyisihan polutan minyak dengan metode co-composting, dan (2) menentukan aplikasi teknologi cocomposting pada proses pengolahan limbah lumpur berminyak di lapangan. Penelitian dilakukan pada skala laboratorium dengan menerapkan metode co-composting selama 60 hari.Variasi yang digunakan adalah variasi komposisi lumpur dan sampah, serta variasi campuran kompos. Variasi komposisi lumpur dan sampah yang digunakan, yaitu: (1) 85% lumpur : 15% sampah; (2) 70% lumpur : 30% sampah; (3) 55% lumpur : 45% sampah; dan (4) 50% lumpur : 50% sampah. Variasi komponen bahan baku kompos yang digunakan adalah sampah basah rumah tangga, serta campuran sampah basah rumah tangga dan kotoran ternak dengan perbandingan 60:40. Reaktor yang digunakan sebanyak 22 buah dengan kapasitas 5L. Proses aerobik dilakukan melalui injeksi udara sebesar 2100 L/jam untuk keseluruhan reaktor. Proses co-composting yang telah berlangsung selama 60 hari mampu menyisihkan polutan minyak sebesar 72% pada komposisi 55% lumpur : 45% sampah basah rumah tangga. Penyisihan polutan minyak sebesar ini terjadi karena adanya kesalahan penggunaan pelarut dalam proses ekstraksi. Pelarut yang seharusnya digunakan adalah n-heksana yang bersifat nonpolar. Aplikasi co-composting di lapangan dapat dilakukan dengan metode trench atau metode in-vessel menggunakan rotary drum. =============================================================================== The workshop of PT Pamapersada Nusantara (PAMA) generates 73 drums/year of hazardous mixed sludge, which is composed of sand/soil, water, and hydrocarbons. This waste is directly given to third party for further treatment. In the cocomposting method, organic pollutant can be added as a cosubstrate. During the composting process, the pollutant can be degraded. Therefore, a research work on the application of cocomposting method for oily sludge treatment will be implemented. The objectives of this research are (1) to determine the oil removal efficiency of the oily sludge using co-composting method, and (2) to determine the field scale application of cocomposting technology in oily sludge treatment process. This research was conducted for 60 days at laboratory scale using PT PAMA oily sludge as a co-substrate and residential biodegradable solid waste (BSW). The variables included sludge-BSW composition, and compost raw materials. Sludge-BSW composition were varied as the following: (1) 85% sludge : 15% BSW; (2) 70% sludge : 30% BSW; (3) 55% sludge : 45% BSW; and (4) 50% sludge : 50% BSW. The compost raw materials were BSW and mixture of BSW and cattle manure of 60:40 ratio. 22 reactors with 5L in capacity were used. The aerobic process was conducted by 2100 L/hour air injection for all of the reactors. The 60 day co-composting process could remove 72% oil pollutant in the reactor of 55% sludge : 45% residential BSW. This high removal efficiency value was caused by an error in using organic solvent during the extraction process. The solvent should be n-hexane which is non-polar. The field scale application of co-composting method for oil removal could be performed by trench or in-vessel methods using rotary drums.
