Limbah cair industri kelapa sawit yang paling utama adalah palm oil mill effluent (POME). POME dapat
merusak ekosistem perairan dan mengkontaminasi rantai makanan jika dibuang langsung ke saluran
pembuangan tanpa diolah terlebih dahulu. Dalam limbah cair kelapa sawit terdapat beberapa komponen
penyusun diantaranya adalah Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), dan
Volatile Fatty Acid (VFA) yang dapat digunakan untuk memproduksi biogas dalam suatu reaktor anaerobik.
Perubahan terhadap kandungan yang terkandung dalam limbah cair pabrik kelapa sawit (LCPKS) tersebut
akan dipengaruhi oleh beberapa faktor salah satunya adalah temperatur. Pada penelitian ini Temperatur yang
digunakan adalah temperatur ambient yaitu mengikuti temperatur lingkungan, temperatur 35˚C dan
temperatur 45˚C, peningkatan temperatur bertujuan untuk mempercepat laju perombakan, sehingga
menghasilkan gas lebih optimal dan proses perombakan yang lebih efisien. Tujuan penelitian ini untuk
mengetahui pengaruh Temperatur terhadap perubahan kadar COD, BOD, dan VFA yang terkandung dalam
limbah cair pabrik kelapa sawit (LCPKS). Adapun persentase removal BOD, COD yaitu sebesar 83,96 %,
84,02% dan untuk VFA tertinggi terdapat pada temperatur 35˚C yaitu sebesar 9.912,45.
Kata Kunci : POME, temperatur, bioreaktor anaerobik, biogas
