“…The most important characteristic possessed by cow dung extract as a growth medium for microorganisms is pH. The pH value of the cow dung extract in this study was included in the optimum condition range, namely 6.4-7.4 so that microorganisms could grow and work properly (Dewi et al, 2018).…”

The tofu industry produces liquid waste containing high organic compounds. Organic compounds in liquid waste can threaten aquatic ecosystems if discharged directly into water bodies. One of the most effective wastewater treatment systems is the treatment using Anaerobic Sequencing Batch Reactor (ASBR). Besides being able to reduce the content of organic compounds, ASBR can produce biogas, and its decomposing microorganisms do not flow into the effluent stream. The purpose of this study was to evaluate the performance of ASBR at an effective reactor volume according to the design. This is because the use of ASBR in previous studies had not reached the operational stage and did not use an effective volume reactor. The stages of waste treatment using ASBR include the seeding, acclimatization, and operation stages. Waste treatment took place at room temperature in the reactor with an effective volume of 6 L. The operating parameters tested were MLVSS, COD, BOD, pH, and cumulative biogas volume. The results obtained show that the seeding process took 56 days, acclimatization took 10 days, and the operation lasted for 17 days. The efficiency of reducing COD concentration was 60%, the efficiency of reducing BOD concentration was 35.65%, and the cumulative volume of biogas produced was 24,120 mL at the operating stage. The use of the ASBR system at an effective volume of 6 L resulted in the successful processing of tofu liquid waste.

Sumber energi terbarukan perlu terus dikembangkan untuk menekan ketersediaan bahan bakar fosil yang sudah semakin menipis. Biogas merupakan salah satu energi alternatif dengan memanfaatkan limbah organik seperti kotoran sapi. Pengolahan kotoran sapi sebagai bahan baku biogas dapat menggunakan biodigester tipe kontinyu dan tipe batch. Biodigester kontinyu selalu berisi 80% umpan dari volume total (50 liter) dan 20% sisanya sebagai ruang gas. Biodigester tipe batch kapasitas 220 liter memiliki komposisi kotoran sapi dan rumput gajah sebesar 25 kg : 25 kg dengan penambahan air 100 liter. Produksi biogas dilakukan selama 70 hari. Hasil penelitian menunjukkan bahwa biodigester kontinyu menghasilkan volume biogas total 17.520 ml dan kandungan CH4 51,37%, sedangkan untuk biodigester batch menghasilkan volume biogas total 66.484 ml dan kandungan CH4 31,37%. Uji nyala untuk biodigester kontinyu menunjukkan bahwa setelah hari ke-12 nyala api berwarna biru dan menyembur cukup kuat pada saat katup pengaturan gas dibuka dan dikenakan api, tetapi pada biodigester batch tidak menghasilkan nyala api karena kadar CH4 kurang dari 45%. Biodigester tipe kontinyu dengan kapasitas 50 L menghasilkan volume biogas lebih tinggi dibandingkan dengan tipe batch yang berkapasitas 220 liter
