      Abstract
      Biogas merupakan produk akhir pencernaan anaerobik dengan kandungan utama berupa CH4 dan CO2. Metana dapat dimanfaatkan sebagai sumber energi terbarukan. Makroalga berpotensi digunakan sebagai bahan baku biogas karena memiliki kandungan karbohidrat dan air yang tinggi serta rendah lignin dibandingkan dengan tumbuhan terestrial. Ulva sp. merupakan makroalga edible memiliki tingkat pertumbuhan yang tinggi 35%/hari di alam. Co-digestion biomassa alga dengan substrat limbah lainnya dapat menginduksi efek sinergis pada kemampuan biodegrasi substrat, menyebabkan peningkatan hasil metana dan tingkat produksi. POME mengandung nutrient untuk bakteri metanogen serta ketersediaan yang melimpah. Penelitian ini bertujuan untuk mengevaluasi potensi produksi biogas menggunakan metode co-digestion dengan perlakuan perbedaan komposisi Ulva lactuca, POME dan kotoran sapi. Parameter-parameter yang dianalisis adalah volume, pH, TDS, EC dan konsentrasi metana (%). Produksi biogas dilakukan menggunakan 2 digester berkapasitas 2 l terbuat dari bahan polikarbonat dengan digester A berisi Ulva sp.+ Kotoran sapi dan digester B berisi POME +Ulva sp.+ Kotoran sapi. Digester A menghasilkan volume kumulatif biogas sebesar 7,17 l dengan produksi metana sebesar 4,83 l sedangkan digester B menghasilkan volume kumulatif biogas sebesar 11,72 l dengan produksi metana sebesar 3,47 l. Hasil penelitian menunjukan bahwa co-digestion Ulva sp dan kotoran sapi lebih efektif dalam menghasilkan metana tanpa ada co-substrat POME.
       
      Anaerobic digestion produces biogas, which mostly contains CH4 and CO2. It is possible to use methane as a renewable energy source. Due to their higher levels of water and carbohydrates and lower levels of lignin when compared to terrestrial plants, macroalgae have the potential to be used as the primary component of biogas. An edible macroalgae, Ulva sp., grows at a rapid pace of 35% per day in nature. Algal biomass co-digestion with other waste substrates can have a synergistic effect on the substrate's biodegradability, increasing methane yields and production rates. POME is widely available and contains nutrients for methanogenic bacteria. This study uses various Ulva lactuca, POME, and cow manure compositions to assess the possibility for producing biogas utilizing the co-digestion method. Volume, pH, TDS, EC, and methane concentration (%) were the parameters examined. Two polycarbonate digesters with a combined capacity of 2 l are used to produce biogas; digester A contains Ulva sp.+ cow manure, while digester B contains POME + Ulva sp.+ cow manure. While digester B produces cumulative volumes of biogas of 11.72 l and 4.47 l methane, digester A produces cumulative volumes of biogas of 7.17 l and 4.83 l methane. The outcomes demonstrated that the production of methane from the co-digestion of Ulva sp. and cow dung was superior without the POME co-substrate.
