Abstract
ABSTRAKBiogas merupakan salah satu sumber energi terbarukan yang murah dan berkategori non-polusi. Kebutuhan untuk memonitor serta mengontrol plant biogas bertambah seiring kebutuhan mengoptimalkan stabilitas proses untuk mendapatkan performansi yang tinggi. Monitoring biogas dapat memberikan gambaran keseluruhan proses pembangkitan biogas dan digunakan untuk memprediksi proses fermentasi yang berlangsung. Selain itu, dapat pula meminimalkan gagalnya proses fermentasi dan menghasilkan biogas secara optimal. Dalam penelitian ini proses monitoring dilakukan pada digester dua tahap berbahan dasar ampas tahu dan difokuskan pada pH dan volume biogas yang dihasilkan menggunakan dfrobot sku Sen0160 dan YF-S201 serta solenoid valve sebagai aktuatornya. Hasil penelitian menunjukkan bahwa set point pH 5.3 pada digester asetogenesis dapat dicapai pada hari ke enam untuk tiga percobaan. Dalam digester metanogenesis nilai pH dapat dijaga pada pH 7 ±0.3. Jumlah volume biogas tertinggi yang dihasilkan sebesar 97.2 L.Kata kunci: digester dua tahap, fermentasi, asetogenesis, metanogenesis ABSTRACTBiogas is one of an inexpensive and non-pollution renewable energy source. A requirement for optimization and stabilization of biogas plant affected on the need of monitor and control system in the plant. Biogas monitoring system represents a process in biogas generation and has the ability to predict fermentation. In addition, the system built can be used to control the fermentation process and to minimize the failure of the process. This means the process will produce biogas optimally. In this research, the monitoring system was used on two stages digester using tofu as raw material. pH and biogas volume produced are two focuses in this study using SKU Sen0160 dan YF-S201 as sensors and solenoid valve as an actuator. For three experiments data show, set point for pH (5.3) is achieved at day sixth for acetogenesis digester. For methanogenesis, pH can be maintained at 7 ±0.3. The highest volume of biogas produced was 97.2 L.Keywords: two stages digester, fermentation, acetogenesis, methanogenesis digester
