The Utilization of Rice Husk Waste and Banana Peels as Adsorbents to Reduce Iron Metal Content and TSS in Lais River Water in Palembang

The water of the Lais River is clearly brown, in addition to the water transportation dock, there is an industrial area along the Lais River. Some of the people who live along the Lais River still use the Lais River water for their daily needs such as bathing and washing. The Lais River is a flow from OKU Regency (Ogan Komering Ulu), Muara Enim Regency, then the Musi River and ends at the Lais River, Kalidoni District, Palembang City. The Lais River is 50 kilometers long and 100 meters wide. The Lais River is a tributary of the Musi River in the West Ilir section. This study aims to determine the comparison of the effectiveness of activated carbon from rice husks and banana peels as adsorbents on the quality of the Lais River water in Palembang City. The Lais River is a tributary of the Musi River which is 50 kilometers long. This study was conducted using activated carbon from rice husks and activated carbon from banana peels which were activated using CH3COOH with a concentration of 1 N 20% and then adsorbed on the Lais River water. the results of the study showed that activated carbon from rice husks and activated carbon from banana peels were able to reduce TSS levels from 571 mg/L to 27 mg/L, Fe (iron) levels from 0.8 mg/L to 0.0 mg/L. The conclusion is that activated carbon from banana peels is more effective than activated carbon from rice husks in reducing river water pollution levels. In this study, the analysis of Fe (iron) content was carried out using the Atomic Absorption Spectroscopy (AAS) method. While to determine TSS levels using gravimetric analysis.
