PENGARUH VARIASI INTENSITAS CAHAYA PADA PHOTOBIOREACTOR TERHADAP PEMBENTUKAN GRANULAR INDIGENOUS MICROALGAL-BACTERIAL CONSORTIUM (G-IMBC) DAN PENYISIHAN POLUTAN PALM OIL MILL EFFLUENT

Palm oil production in Riau Province reached 8.97 million tons in 2022 along with
the wastewater produced. Each ton of oil palm fresh fruit bunches will produce 0.7-
0.8 m3 of Palm Oil Mill Effluent (POME) which is treated with conventional
systems. However, the conventional system produces greenhouse gases and
residual nutrients that can be utilized by microorganisms through mutualism
symbiosis between microalgae-bacteria in the formation of G-IMBC. The purpose
of the research was to identify microalgal-bacterial indigenous in POME, analyze
the characteristics and performance of G-IMBC on removal nutrient. Microalgalbacterial consortium was inoculated into a photobioreactor and operated in batch
treatment mode for 24 days under different light intensities at 100 µmol/m2
/s, 150
µmol/m2
/s, and 210 µmol/m2
/s. The identification results showed that there were
four isolates microalgae namely Chlorella sp., Chlamydomonas sp., Oscillatoria
sp., and Euglena sp. The identification results showed that there were three isolates
of gram-positive bacteria in the form of bacillus, namely PM-3, PM-5, and PM-6,
and one isolate of gram-negative bacteria in the form of bacillus, namely PM-1,
and two isolates of gram-negative bacteria in the form of coccus, namely PM-2 and
PM-4. The G-IMBC formed has a compact and dense structure with a diameter of
0.84-1.5 mm, density of 3.62 g/mL, VSS of 11.92 mg/L, and SVI5 of 28 mL/g. The
best COD and total nitrogen removal efficiency values were 91.6% and 99.47%.
