Abstract
Limbah organik dari kantin mempunyai potensi untuk diolah menjadi biogas melalui proses anaerobic digestion (pencernaan anaerob) dengan menggunakan alat bioreaktor
anaerob. Limbah organik terdiri dari sampah dapur dan sisa makanan seperti buah, sayur,daging dan ikan. Hasil berupa biogas tersebut dapat dimanfaatkan oleh para pedagang yang
ada di kantin. Untuk itu pada penelitian ini akan dibuat portable bioreaktor anaerob menggunakan tangki bekas dengan ukuran 1000 liter. Tangki tersebut dimodifikasi dengan
membuat jalur feeding, overflow dan outlet biogas. Parameter yang perlu dimonitor untuk mengetahui kinerja bioreaktor adalah temperature, pH dan pressure. Pengukuran temperature
menggunakan TIC dan sensor RTD PT100 yang dipasang di dalam tangki. Kemudian pengukuran pH diambil melalui sampling dari endapan yang tersimpan di tangki dan diukur oleh pH meter. Untuk pressure akan menggunakan pressure gauge sebagai pengukuran yang diletakkan di bagian atas bioreaktor. Proses feeding awal pada bioreaktor dengan mencampur kotoran sapi dan air dengan perbandingan 1:1, setelah itu akan diamati pengukuran kinerjanya. Didapatkan hasil kinerja bioreaktor pada pagi, siang dan sore untuk temperature ada di rentang 28C-30C, pH di rentang 6.4-7.4 dan pressure mulai naik dan menghasilkan biogas di hari ke- 15. Dalam proses feeding kedua, limbah yang digunakan berupa kulit buah-buahan yang dicincang lalu ditambahkan air dan dimasukkan melalui jalur feeding. Didapatkan hasil kinerja bioreaktor pada pagi, siang dan sore untuk temperature ada di rentang 28˚C-33˚C, pH di rentang 5.4-7.2 dan pressure yang fluktuatif dengan pembacaan tertinggi 7 kPa. Komposisi biogas yang dihasilkan yaitu CH4 ada di keadaan low dan terbaca 49%, CO2 terbaca HIGH dan H2S terbaca 0 ppm.

Organic waste from canteens has the potential to be processed into biogas through anaerobic digestion using an anaerobic bioreactor. Organic waste consists of kitchen waste and food waste such as fruit, vegetables, meat and fish. The results in the form of biogas can be utilized by traders in the canteen. For this reason, this research will make a portable anaerobic bioreactor using a used tank with a size of 1000 liters. The tank is modified by making a feeding line, overflow and biogas outlet. Parameters that need to be monitored to determine the performance of the bioreactor are temperature, pH and pressure. Temperature
measurement uses TIC and RTD PT100 sensors installed in the tank. Then the pH measurement is taken through sampling of the sediment stored in the tank and measured by a pH meter. For pressure, we will use a pressure gauge as a measurement placed at the top of the bioreactor. The initial feeding process in the bioreactor by mixing cow dung and water in
a ratio of 1:1, after which the performance measurements will be observed. The results of the bioreactor performance in the morning, afternoon and evening for temperature were in the range of 28C-30C, pH in the range of 6.4-7.4 and pressure began to rise and produce biogas on day 15. In the second feeding process, the waste used is in the form of fruit peels which are chopped and then added to water and entered through the feeding line. Bioreactor
performance results were obtained in the morning, afternoon and evening for temperature in the range of 28˚C-33˚C, pH in the range of 5.4-7.2 and fluctuating pressure with the highest reading of 7 kPa. The composition of biogas produced, namely CH4 is in a low state and reads 49%, CO2 reads HIGH and H2S reads 0 ppm.
