Pemanfaatan Kulit Durian (Durio Zibethinus) Sebagai Biokoagulan Dalam Aplikasi Air Sintetik Dan Air Gambut

---

The durian rind (Durio zibethinus) constitutes the largest portion of the durian and was often discarded as waste. On the other hand, it contains active components such as protein and cellulose, which can act as coagulating agents. This research aims to prepare biocoagulants, identify its properties, and detect its coagulation ability in synthetic water and peat water. The biocoagulants from durian rind were prepared in three ways, without microwave heating (BNM), with microwave heating (BM) and protein extraction using 1 M NaCl (BE). Characterization of the biocoagulants included functional groups identified using FTIR, surface morphology using SEM, water content gravimetrically and protein content using the Lowry method. Three biocoagulants were applied to synthetic water to treat color and turbidity and to peat water, namely color, turbidity, TSS and TDS. The coagulation process was observed using a jar floc test with varying doses of the biocoagulant (0,1-1) g and a biocoagulant extract volume of (1-5) mL in 300 mL of synthetic water. Determination of the effectiveness of biocoagulant performance can be seen from the results of the color and turbidity of synthetic water after coagulation. The optimum conditions of the three biocoagulants in synthetic water applications were subsequently applied to peat water. The results of FTIR analysis of biocoagulant (BNM, BM and BE) show the presence of O-H (hydroxyl), N-H (amine), C=O (amide) groups. The surface morphology of BNM biocoagulant shows a chip-shaped surface, while BM biocoagulant has a round shape. BNM and BM biocoagulants had water content of 8.99% and 7.57%, respectively. The protein content produced by BNM, BM and BE were respectively 2.68%, 2.27% and 3.10%. BE biocoagulant with a volume of 2 mL was able to remove color and turbidity of 88.21% and 96.14% respectively from synthetic water, while the BE biocoagulant with a volume of 2 mL in peat water was only able to remove turbidity, TSS, TDS of 45.88%, 10% and 31.79% respectively. The use of BE biocoagulant was more effective than BM and BNM biocoagulants in improving peat water quality. Additionally, BE biocoagulant exhibited the lowest sludge volume and shortest sedimentation time (0.1 mL and 4 hours) compared to BNM and BM.
