KINERJA ARANG AKTIF CANGKANG BIJI KARET UNTUK MENINGKATKAN KUALITAS pH AIR GAMBUT PASCA KOAGULASI: PENGARUH DOSIS ADSORBEN

Abstract

Rubber seed shells have chemical composition of cellulose, lignin, and pentosan as a carbon source, which potentially to be used as charcoal which functions as an adsorbent. This research aims to convert rubber seed shells into charcoal through a carbonization process and activated with various concentrations of ZnCl2 (5; 10; 15%), then applied for post-coagulation peat water treatment. The best concentration of rubber seed shells activated charcoal (ACBK) was contacted with post-coagulation peat water with various dosages (1; 1.5; 2 g). The resulting ACBK was characterized by determined the moisture content and ash content gravimetrically,and iodine absorption capacity. The best adsorption results were carried out by ACBK 5% at a dose of 1.5 g was able to increased pH from 2.89 to 6.5. The value has been qualified into PERMENKES RI No.32 of 2017 about Environmental Health Quality Standards and Water Health Requirements for Sanitation Hygiene Purposes.
