Abstract

Salak, snake skin fruit, is one of many kind fruit that is much preferred by people because its taste is sweet, crunchy and because it has a high nutrient content and have good prospects for cultivated. During this time, only flesh fruit of salak are utilized and the seed become waste. Therefore, it has been done a research about biocharcoal of salak seed (salacca edulis) as an absorbent for chromium. The method used in this study was a laboratory experiment using salak seeds biocharcoal as the adsorbent for chromium, concentration of absorbed chromium was measured by using a spectrodirect spectrophotometer. The results showed that the optimum time for adsorption of metal ion chromium obtained was 60 minutes with the absorption efficiency of 99.67%, while the optimum weight for absorption of metal ion chromium obtained was 80 mg with the absorption efficiency of 99.70% and the optimum concentration for absorption of metal ion chromium was 80 ppm with the absorption efficiency of 99.77%.
