SINTESIS KOMPOSIT KARET ALAM SIR 20-ARANG CANGKANG BUAH KARET TERAKTIVASI ASAM SULFAT-PASIR COR SEBAGAI MEDIA PENGOLAHAN AIR GAMBUT

Abstract

Composite is a material formed from two or more mixtures with different chemical and physical properties to produce a new material. The composite materials used in this study were SIR 20 natural rubber as a matrix, activated charcoal from rubber fruit shells and cast sand as filler. Composites were made by varying the filler materials, namely natural rubber SIR 20-100% activated carbon-0% cast sand (KA), natural rubber SIR 20-50% activated carbon-50% cast sand (KAP I), natural rubber SIR 20- activated carbon 75%-cast sand 25% (KAP II), natural rubber SIR 20-activated carbon 25%-sand cast75% (KAP III) natural rubber SIR 20-activated carbon 0%-cast sand 100% (KP) while the control consists of 4 sheets of natural rubber SIR 20. Composites were applied for peat water treatment in Rimbo Panjang Village. The results showed that the analysis of color parameters, pH, TSS and TDS after filtering with composites, showed natural rubber SIR 20-activated carbon 100%-cast sand 0% (KA) was able to improve color quality, TSS and TDS respectively by 30, 63%; 90.12; 91.12%;97.95% and can increase the pH from 3.66 to 6.98.
