Pengaruh Penambahan Biokoagulan Biji Melon (Cucumis Melo L.) Dalam Menyisihkan Fraksi Hidrofobik Dan Fraksi Hidrofilik Air Gambut

ABSTRACT
Peat water has characteristics of reddish-brown color, acidic pH, and high dissolved organic matter content, especially hydrophobic and hydrophilic fractions. These fractions cause the formation of disinfection by-products (DBPs) such as THM and HAA, which are harmful to health. Coagulation is an effective method used to reduce organic matter content in peat water, but the use of synthetic coagulants poses problems for health and the environment. Biocoagulants can be used as an alternative to chemical coagulants. This study aims to analyze the effectiveness of biocoagulants from melon seeds (Cucumis Melo L.) in removing organic matter, hydrophobic fractions, and hydrophilic fractions in peat water. The melon seed biocoagulant dosage varied between 8 g/L, 9 g/L, 10 g/L, 11 g/L, 12 g/L, and 13 g/L. The coagulation process was carried out by rapid stirring at 100 rpm for 1 minute, followed by slow stirring at 40 rpm for 20 minutes, and sedimentation for 15 minutes at a pH of 2. Organic fractionation was analyzed using Amberlite XAD-8, XAD-4, and IRA-958 resins to separate strong hydrophobic (HPOA), weak hydrophobic (TPH), charged hydrophilic (HPIC), and neutral hydrophilic (HPIN) fractions. The optimum dose of melon seed biocoagulant was obtained at a dose of 11 g/L, which could remove organic matter from 347.6 mg/L to 300.2 mg/L. The biocoagulant effectively removed the HPOA fraction that causes color in peat water, but increased the concentration of the HPIN fraction after the coagulation process.
