Abstract:
Composite is a combination of several materials with different properties and
types so that it was formed material with new properties. In this study, natural
rubber latex, activated charcoal of peanut shells were activated by 5% sulfuric
acid (H2SO4), cast sand and, palm fiber were used as raw materials for making
composite. The composite was made with seven variations of filler, 100%
activated charcoal (KA), 100% cast sand (KP), 100% palm fiber (KI), 50%
activated charcoal: 50% cast sand (KAP), 50% activated charcoal: 50% palm fiber
(KAI), 50% cast sand: 50% fiber palm fiber (KPI) and 33.3% activated charcoal:
33.3% cast sand: 33.3% palm fiber (KAPI). The resulting composite was
implemented a river water filter, which is Kampar Kiri River. The water
parameter analyzed were based on analysis of color, pH, TDS and, TSS. Based on
the result, KA composite showed the best performance to reduce color intensity
by 93.43%, TSS 92.13%, TDS 99.84% and, neutralized pH from 6,1 to 7,01.
