Pengaruh Penambahan Biokoagulan Kacang Tunggak (Vigna Unguiculata L.) Dalam Menyisihkan Fraksi Hidrofobik Dan Fraksi Hidrofilik Air Gambut

ABSTRACT
Peat water contains high levels of dissolved organic matter (DOM). DOM can be classified into four fractions, which are strongly hydrophobic (HPOA), weakly hydrophobic (TPH), charged hydrophilic (HPIC), and neutral hydrophilic (HPIN). These fractions can cause the formation of disinfection by-products (DBPs) such as THM and HAA, so treatment is need to make it suitable for daily use. The treatment method that can be used is the coagulation-flocculation process using cowpea biocoagulant. The purpose of this study was to analyze the effect of cowpea in removing organic substances from peat water and to analyze the effect of cowpea on the content of HPOA, TPH, HPIC, and HPIN fractions before and after the coagulation-flocculation process. The preparation of cowpea consists of drying the cowpea under the sun for 7 days, then grinding it with a blender and sieving it with a 200 mesh sieve. The coagulation-flocculation process was carried out using a jar test with varying doses of 1,5; 2; 2,5; 3; 3,5; and 4 g/L at pH 3, with rapid stirring at 100 rpm for 1 minute, slow stirring at 40 rpm for 20 minutes, and settling for 15 minutes. The organic matter fractionation process was carried out using Amberlite XAD-8, XAD-4, and IRA-958 resins. The results showed that the optimal dose of 3 g/L of black bean extract could reduce the organic matter concentration from 347.6 mg/L to 237 mg/L. The highest fraction content before and after the coagulation-flocculation process was HPOA and HPIN, while the lowest content was HPIC and HPOA.
Keywords: peat water, coagulation-flocculation, cowpea, hydrophobic, hydrophilic
