摘要

木薯(Manihot utillisima)是印尼人的主食,仅次于大米和玉米。木薯是一种天然产品,在印度尼西亚非常丰富,特别是在中塔瓦和西爪哇地区。活性炭是由碳材料经燃烧或热分解而成的多孔材料。活性炭广泛用于水净化、医药、废物处理和压缩空气过滤器(Lam et al., 2017)。本研究的目的是研究木薯皮活性炭的吸附能力,木薯皮活性炭作为水过滤器,特别是对铜(II)金属的去除与多种活化剂的最佳接触时间和使用活性炭在简单的家用规模的水过滤器。结果表明,咖啡渣活性炭的产率、含水率、灰分、碘吸收率等指标均符合SNI No.06-3730- 1995活性炭质量标准。浓度越高,活性炭对Cu (II)金属的吸收量越大,从变化数据来看,活化剂的最佳选择是活化剂KOH浓度为0.3 m的活性炭。活性炭在5小时内装箱,平均产率为0.1898毫克/升,符合清洁水标准,即根据2008年东爪哇地区法规,其中规定水中铜含量为每升0.2毫克的阈值。

Penggunaan Limbah Kulit Singkong pada Filter Air Sederhana Skala Rumah Tangga
Cassava (Manihot utillisima) is a staple food for Indonesians after rice and corn. Cassava is a natural product (product) which is abundant in Indonesia, especially in the areas of Central Tawa and West Java. Activated carbon is a porous material derived from carbon material by combustion or thermal decomposition. Activated carbon is widely used for water purification, medicine, waste treatment and as a filter in compressed air (Lam et al., 2017). The purpose of this research is the quality of activated charcoal from cassava peel absorption capacity of activated carbon from cassava peels as a water filter, especially for removal of Cu (II) metal with a variety of activators and the optimum duration of contact with the use of activated carbon in a simple home scale water filter. The results showed that the quality of activated charcoal from coffee grounds which includes the quality of yield, moisture content, ash content and absorption of iodine has met SNI No.06-3730- 1995 Activated Charcoal Quality Standards. The higher the concentration, the greater the absorption of activated charcoal on Cu (II) metal, and from the variation data the most optimal activator is activated charcoal with a KOH activator of 0.3 m. The results of boxing the activated charcoal within 5 hours with an average yield of 0.1898 mg per liter meet the clean water standards, namely according to the 2008 East Java Regional Regulation which states that the Cu content in water is at a threshold of 0.2 mg per liter.
