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.
