Abstract

Small medium enterprise badminton racket in Malang consume water wastefully. Rinse water discharged into river and causing pollution problem. In fact, rinse water can still be utilized. Rinse water can be reused for anodizing other racket. The results showed that the rinse water could be used five times and the impact on saving electricity and water resources. Rinse water used to anodize produced products that are not much different if the new rinse water is used.

Abstract

This research studied to utilize the bagasse to be used as activated karbon in particular for the adsorption of Ca2+. The manufacture of activated carbon consists of carbonization dan activation process. Temperature variation for carbonization process in this research are 500°C, 550°C, 600°C, 650°C and 700°C then proceed with the activation process by carbon reflux with 6 M H2SO4 for 4 hours. Carbonization yield will decrease with increasing temperature carbonization. While the ash content, surface area, pore volume, and adsorption capacity of Ca2+ will increase with increasing temperature of carbonization. Obtained activated carbon is best activated karbon made at a temperature of 700°C with an activation carbonization which has a surface area 100.62 m2/g, 22.3750 Å pore diameter, pore volume of 22.376 mL/g, can eliminate the Ca2+ up to 13.26 %.
