Kinerja Biokoagulan Dari Ekstrak Biji Pepaya (Carica Papaya) Untuk Meningkatkan Kualitas Air Gambut

---

Papaya seed (Carica papaya) is a plant material derived from the papaya fruit that is not maximally utilised and becomes waste that is not used by the community. Papaya seeds have active components in the form of proteins that can act as coagulant agents. This study aims to prepare, characterise and determine the effectiveness of the effect of particle size and solvent concentration on papaya seed extract biocoagulant evaluated based on the removal of turbidity, colour, TSS, TDS and organic matter of peat water. Papaya seeds were prepared with different particle sizes (100, 120 and 200 mesh) and NaCl solvent concentrations (0.01; 0.1; 0.5 and 1) M. Peat water coagulation was carried out at pH 2 using jar floc test with a biocoagulant dose of papaya seed extract of 30 mL. Characterisation of the biocoagulant included functional groups identified by FTIR and protein content by Lowry method. The results of FTIR analysis of papaya seed extract biocoagulant showed the presence of O-H (carboxylate), C=O (amide) functional groups. The highest protein content in this study was obtained at 1 M NaCl solvent concentration of 9.60%. The most effective biocoagulant performance in peat water treatment was obtained from the biocoagulant prepared with 100 mesh size and 0.5 M NaCl solvent concentration (BP100-0.5). Biocoagulant BP100-0.5 was able to remove 99.07% turbidity, 93.43% colour, 90.90% TSS, 94.43% TDS and 68.03% organic matter with a sedimentation time of 33 minutes and a sludge volume of 16 mL. Papaya seed extract is able to remove more than 90% of the peat water pollutants, however, in the parameters of colour and organic matter, the peat water after coagulation does not meet all the test parameters in the regulations of PERMENKES RI No. 32 of 2017 and PP No. 22 of 2021.
