[ Description ]
Biogas merupakan campuran gas-gas methana, karbon dioksida, hidrogen sulfat, nitrogen dan gas-gas lainnya yang dihasilkan dari proses penguraian bahan-bahan organik oleh mikro organisme pada kondisi anaerob. Rangkaian proses penguraian anaerob terdiri dari tahapan hidrolisis, pengasaman dan pembentukan gas CH4. Laju produksi biogas dalam digester, utamanya dipengaruhi oleh suhu digester dan proses pengadukan material umpan. Oleh karena itu, dalam penelitian ini ingin diketahui pengaruh dari kedua parameter tersebut terhadap laju produksi biogas.
Penelitian ini menggunakan bahan baku kotoran sapi pada anaerobic digester biogas type horizontal yang dilengkapi dengan system pemanas berupa water jacket dan sistem pengaduk. Water jacket dipanaskan oleh pemanas listrik dan dilengkapi dengan temperatur sensor, sedangkan sistem pengaduk digerakkan oleh motor listrik. Sensor suhu disetting mulai 30 °C s/d 38 °C dengan interval kenaikan suhu sebesar 20C dan putaran pengaduk 140 rpm dengan sistem ON-OFF selama 10 menit untuk tiap 2 jam selama 10 periode. Setting 5 periode tanpa pengaduk dan 5 periode dengan pengaduk. Hasil menunjukkan bahwa pemanasan dapat meningkatkan produksi biogas rata-rata 3,1 % setiap kenaikan 2 °C dan maksimum pada suhu 38 °C dengan produksi rata-rata sebesar 2,0 % sedangkan pemanasan dan pengadukan dapat meningkatkan produksi biogas rata-rata 5,6 % setiap kenaikan 2 °C dan maksimum juga pada suhu 38 °C dengan produksi rata-rata sebesar 4,9 % Pengaruh pemanasan dan pengadukan waktu tinggal HRT menjadi lebih singkat akibat produksi biogas optimum lebih awal yaitu rata-rata terjadi pada minggu II . Reduksi degradasi maksimum TS, TVS, COD dan BOD untuk periode pengisian 38 °C dan dengan terjadi pada minggu ke I HRT dengan menghasilkan produksi biogas maksimum. Untuk kualitas gas pada pemanasan tersebut selama periode pengisian untuk 38 °C dan dengan pengaduk berjalan adalah metan 56,32 %, CO2 35,64 %, O2 1,56 %, H2 2,7 %, N2 1,56 % dan H2S 2,17 %.
Alt. Description
Biogas is a mixture of gases methane, carbon dioxide, hydrogen sulfate, nitrogen and other gases produced from the decomposition of organic materials by micro-organisms in anaerobic conditions. The series of anaerobic decomposition process consists of stages of hydrolysis, acidification and the formation of CH4 gas. The rate of production of biogas in the digester, mainly influenced by temperature and stirring process the feed material. Therefore, in this study wanted to know the influence of both these parameters on the rate of biogas production.
This study used raw materials cow manure in an anaerobic digester biogas horizontal type of heating system is equipped with a water jacket and stirrer system. Water is heated by electric heating jacket and equipped with temperature sensors, while the system is driven by an electric motor stirrer. The temperature sensor gives a chance to start 30 °C to 38 °C with intervals of rising temperatures of 20C and 140 rpm stirrer rotation with the system ON-OFF for 10 minutes to every 2 hours during 10 periods. Setting 5 periods without stirring and 5 periods with a stirrer.
The results indicate that heating could increase the average biogas production of 3.1% every increase of 2 °C and a maximum at a temperature of 38 °C with an average production of 2.0% while stirring can increase biogas production an average of 5. 6% of every increase of 2 °C and maximum temperatures also at 38 °C with an average production of 4.9%. Effect of heating and stirring, the residence time HRT became shorter due to earlier optimal biogas production which occurred on average at second week.
Reduction of the maximum degradation of TS, TVS, COD and BOD for the charge period to 38 °C and occurred at first week HRT by generating maximum biogas production. For quality gas on heating during the feeding period to 38 °C and the stirrer runs are methane 56.32%, CO2 35.64%, O2 1.56%, H2 2.7%, N2 1.56% and H2S 2.17%.
