Abstract

Abstract. A crucial indicator of biogas power plant performance is the quality of the biogas entering the gas engine. Poor-quality biogas causes issues such as startup failures, corrosion of intercooler fins, and scoring of pistons and cylinders, in addition to reducing oil lifespan. Therefore, this study aims to detect performance degradation in the biogas power plant by measuring its operational performance using Key Performance Indicators (KPIs). The performance measurement process revealed declines in specific areas, namely the digestion KPIs regarding inlet pH and inlet temperature; this was attributed to the absence of a cooling pond system and a mixing pit at the plant. Regarding biogas condition KPIs, H2S and O2 levels were found to be suboptimal. However, gas engine consumption metrics were within acceptable limits, with consumption below 2 kWh/m³ and a Capacity Factor (CF) of 45%. Based on these measurements, optimization of the biogas system is required, as H2S and O2 levels did not meet KPI standards. The study concludes that KPIs can serve as a valuable reference for assessing and integrating the performance of biogas power plants.

Abstract

Pembangkit listrik tenaga biogas terdapat beberapa factor yang menyebabkan penurunan kinerja salah satunya adalah kualitas biogas. Biogas yang buruk menyebabkan masalah seperti kegagalan starting, korosi pada sirip intercooler, serta piston dan silinder tergores selain itu mengurangi umur oli. Oleh karena itu penelitian ini bertujuan mendeteksi penurunan kinerja pembangkit listrik tenaga biogas dengan melakukan evaluasi dan mengoptimalkan kinerja biogas condition dengan melakukan pemeliharaan di unit scrubber. Metode yang digunakan yaitu menerapkan key performance indicator (KPI) dan pemeliharaan korektif. Dalam proses evaluasi terdapat beberapa penurunan kinerja yaitu KPI digester pada parameter pH in, T in dan POME in. KPI biogas condition pada parameter H2S dan O2. KPI gas engine pada parameter excess power generation/IPP. Hasil optimalisasi setelah pemeliharaan H2S dan O2 berstatus baik. Dari penelitian ini didapatkan bahwasanya key performance indicator (KPI) dapat digunakan sebagai acuan untuk mengetahui dan memantau kinerja pembangkit listrik tenaga biogas.
