PENGARUH VARIASI RASIO INOKULUM TERHADAP PEMBENTUKAN DAN KARAKTERISASI GRANULAR INDIGENOUS MICROALGAL-BACTERIAL CONSORTIUM (G-IMBC) DARI PALM OIL MILL EFFLUENT (POME)

---

Palm Oil Mill Effluent (POME) is wastewater derived from the production of crude
palm oil (CPO) that can pollute water bodies. Generally, POME is treated using
conventional systems, but the treated POME still contains nutrient-rich organic
compounds such as carbohydrates, organic acids, and nitrogen. The remaining
organic compounds can be utilized as a growth medium for microalgae and
bacteria in the formation of the Granular Indigenous Microalgal-Bacterial
Consortium (G-IMBC). This research aims to identify indigenous microalgaebacteria that play a role in the formation of G-IMBC and study the effect of
variations in the inoculum ratio on the formation and characterization of G-IMBC
based on granular shape, size, and density, VSS, SVI5, and performance tests of
COD and total nitrogen removal. The study was conducted using 4 variations of
microalgae-activated sludge inoculum ratio, which consist of 0:1, 1:1, 1:3, and 3:1
(v/v) within 24 days in a photobioreactor (PBR). The results of the identification of
indigenous microalgae obtained 4 isolates, namely Chlorella sp., Chlamydomonas
sp., Oscillatoria sp., and Euglena sp. The results of the identification of indigenous
bacteria obtained 1 isolate of bacillus-shaped and 2 isolates of cocci-shaped gramnegative bacteria, also 3 isolates of bacillus-shaped gram-positive bacteria. The
best G-IMBC formation was obtained at an inoculum ratio of 1:3 with a compact
granular structure, a granular diameter of 0.9–1.2 mm, a VSS of 10.58 g, a SVI5 of
31 mL/g, and a granular density of 3.2 g/mL, and the best COD and total nitrogen
removal efficiency of 91.6% and 94.75%, respectively.
