    The effect of total solid (TS) content and feedstock/inoculum (F/I) ratioĀ  on biogas production from corn stover by solidā€state anaerobic digestion (SSā€AD) were studied. At a F/I ratio of 2, conversion of corn stover under room temperature resulting in higher biogas yield. SSā€AD performed as expected at the TS content of 20%, 22%, 24%. The highest biogas yield of 200 L kgā€1 volatile solids (VS) was obtained at TS content of 22%, F/I ratio of 2

    Bahan bakar minyak memiliki dampak negatif terhadap lingkungan yaitu meningkatkan emisi karbon dioksida (CO2). Oleh karena itu, perlu mencari sumber energi alternatif untuk menurunkan ketergantungan bahan bakar minyak danĀ memasok energi konsumsi domestik. Salah satu sumber energi terbarukan yangĀ paling menjanjikan adalah biogas. Tujuan dari penelitian ini adalah untukĀ membandingkan model kinetik untuk produksi biogas dari jerami jagung denganĀ limbah makanan sebagai co-digestion menggunakan persamaan linear danĀ eksponensial. Penelitian ini dilakukan pada variasi rasio F/I 2,3,4 dengan komposisiĀ limbah makanan 10%. Kecepatan pembuatan biogas tertinggi diperoleh pada F/I 2.Ā Model eksponensial memiliki nilai korelasi yang lebih tinggi dibandingkan denganĀ model linier pada periode naik. Namun, model linier memiliki nilai korelasi yangĀ lebih tinggi dibandingkan eksponensial pada periode menurun

    Biogas Production from Corn Stover by Solid-State Anaerobic Co-digestion of Food Waste

    Biogas has become an alternative fuel to reduce the lack of fossil fuel. Biogas can be produced from organic wastes such as corn stover. Corn stover is a typical lignocellulosic biomass and contains a total solid (TS) content higher of 15%. Biogas production was conducted by solid-state anaerobic digestion with addition co-digestion of food waste. Co-digestion is useful to help the digestion of corn stover. The purposes of this study were to investigate the effect of the percentage of food waste, volatile solid (VS) reduction, and kinetic model on biogas production from corn stover. Results showed that food waste had a significant effect on biogas yield (p < 0.05). The highest biogas yield of 584.49 mL g-1 VS-1 and the highest VS reduction of 40% was obtained at food waste of 20%. The kinetic model of biogas production from corn stover and food waste followed the first-order kinetic model
