Abstract
Rubber seed shell (Hevea brasiliensis) is a by-product of the rubber plant. Rubber
seed shells contain high cellulose, lignin and pentosan compounds so that they can be
used as adsorbents for post-coagulation-adsorption peat water purification. In this
study, rubber seed shells were carbonized at a temperature of 500oC for 15 minutes
and activated with various concentrations of KOH (0; 5; 10; 15%). The rubber seed
shell charcoal produced was characterized by water content, ash content and iodine
adsorption capacity, so that the best concentration of activated charcoal with activated
rubber seed shell activated KOH 10% was obtained. Rubber seed shell activated
charcoal was applied to peat water after coagulation-adsorption in various doses (1;
1.5; 2) g with a contact time of 15 minutes. The best condition of activated charcoal
was in sample A1 with a percentage of color removal of 95,96%. The purification of
peat water using activated charcoal as an adsorbent of rubber seed shells has been
able to improve the quality of peat water with color parameters in accordance with
the PERMENKES RI No. 32 of 2017 concerning Environmental Health Quality
Standards and Water Health Requirements for Sanitary Hygiene Needs.
