Abstract
Penelitian ini dilakukan untuk identifikasi biohidrogen dari proses fermentasi kultur campuran menggunakan variasi konsentasi sukrosa sebagai substrat. Fermentasi menggunakan sistem batch yang berlangsung selama 33 jam (konsentrasi 1% dan 3%) dan 64 jam pada konsentrasi 2%. Kondisi fermentasi diatur pada pH 5-6, suhu 40°C dan disampling tiap 2 jam sekali. Analisa kualitatif menggunakan Hydrogen Sensor menunjukkan adanya gas hidrogen yang dilanjutkan dengan analisa kuantitatif menggunakan GC sehingga didapatkan hasil berupa prosentase hidrogen pada konsentrasi 1%, 2% dan 3% adalah 11,37%; 13,57% dan 18,53%. Volume hidrogen kumulatif yang didapatkan dari volume total biogas pada konsentrasi 1%, 2%, 3% berturut-turut adalah 39,75 mL; 63,78 mL dan 157,50 mL.

This study aims to identify biohidrogen of mixed culture fermentation process using a variety of concentrations of sucrose as a substrate. Fermentation using a batch system that lasts for 33 hours (concentration of 1% and 3%) and 64 hours at a concentration of 2%. Fermentation conditions set at pH 5-6, temperature 40°C and sampled every 2 hours. Qualitative analysis using Hydrogen Sensor indicate a hydrogen gas, followed by quantitative analysis using GC so we get a percentage of hydrogen at a concentration of 1%, 2% and 3% is 11.37%; 13.57% and 18.53%. Cumulative volume of hydrogen obtained from the total volume of biogas at a concentration of 1%, 2% 3% is 39,75 mL; 63,78 mL and 157,50 mL, respectively.
