Abstract

Crude Palm Oil merupakan salah satu minyak nabati yang paling banyak diproduksi di dunia. Produksinya menghasilkan limbah cair yang dikenal sebagai Palm Oil Mill Effluent (POME), yang memiliki kandungan COD tinggi dan berpotensi mencemari lingkungan. Pengolahan anaerobik menjadi salah satu metode efektif untuk mengolah POME sekaligus menghasilkan biogas sebagai energi terbarukan. Penelitian ini bertujuan untuk mengetahui pengaruh waktu terhadap volume biogas yang dihasilkan dan mengetahui perbandingan konsentrasi dalam percent of weight dari kotoran sapi + air (1:1 dan 1:2) yang optimal sesuai dengan karakteristik biogas. Prosedur penelitian meliputi pre-treatment, persiapan substrat dan inokulum, fermentasi, Analisa pH, COD, TS, volume biogas, serta uji nyala dan evaluasi. Hasil menunjukkan volume biogas tertinggi pada hari ke-14, dengan perbandingan 1:1 menghasilkan 3,125 L/hari dan 1:2 sebesar 2,2 L/hari. Serta diperoleh perbandingan rasio berat kortoran sapi dan air terbaik yaitu 1:1 dimana menghasilkan volume sebesar 3,125 L/hari. Dengan uji nyala api biru dimana lebih baik dari rasio 1:2 yang menunjukkan nyala biru kemerahan, menandakan adanya gas pengotor. Hasil uji total solid sebesar 37,09%, juga sesuai dengan literatur bahwa peningkatan total solid menurunkan volume biogas. Dan hasil Gas Chromatography menunjukkan hasil kadar metana sebesar 37,17% pada perbandingan 1:1, masih di bawah standar ideal (±50%). Uji COD awal sebesar 4245,81 mg/L dengan percent recovery sebesar 2% sehingga COD effluent sebesar 4143,39 mg/L, yang belum memenuhi baku mutu limbah industri sawit (300 mg/L). =================================================================================================================================
Crude Palm Oil (CPO) is one of the most widely produced vegetable oils globally. Its production generates liquid waste known as Palm Oil Mill Effluent (POME), which contains high levels of COD and poses a risk to the environment. Anaerobic digestion is an effective method to treat POME while producing biogas as a renewable energy source. This study aims to examine the effect of retention time on biogas volume and determine the optimal concentration ratio by percent weight of cow dung and water (1:1 and 1:2) based on biogas characteristics. The experimental steps included pre-treatment, substrate and inoculum preparation, fermentation, and analysis of pH, COD, TS, biogas volume, flame test, and gas composition. Results showed that the highest biogas production occurred on day 14, with 3.125 L/day at a 1:1 ratio and 2.2 L/day at a 1:2 ratio. The 1:1 ratio produced a stable blue flame, indicating higher methane quality, compared to the reddish-blue flame from the 1:2 ratio. The total solids content was 37.09%, aligning with literature that increased TS reduces biogas yield. Gas Chromatography analysis showed a methane content of 37.17% for the 1:1 ratio, still below the ideal standard (~50%). Initial COD was 4245.81 mg/L with 2% recovery, resulting in effluent COD levels of 4143.39 mg/L, which do not meet the palm oil industry wastewater standard of 300 mg/L.
