Abstract

Telah dilakukan penelitian adsorpsi metilen biru pada adsorben abu layang (fly ash) hasil pembakaran cangkang sawit pada boiler. Adsorben abu layang terlebih dahulu dipersiapkan dengan aktivasi kimia menggunakan H3PO4 10% dan tanpa aktivasi sebagai pembanding. Hasil penelitian menunjukkan bahwa adsorpsi metilen biru pada abu layang tanpa aktivasi maupun dengan aktivasi  mengikuti model kinetika orde dua semu menurut Ho dengan nilai R2 sebesar 0,990 untuk adsorben tanpa aktivasi dan 0,996 untuk adsorben dengan aktivasi. Isotherm adsorpsi zat warna metilen biru pada abu layang mengikuti model isotherm menurut Freundlich dengan nilai R2 sebesar 0,988 (kapasitas adsorpsi 19,81 mg/g) untuk abu layang tanpa aktivasi dan sebesar 0,991 (kapasitas adsorpsi 60,11 mg/g) untuk abu layang dengan aktivasi.

Abstract

Ground Water quality has a special significance for drinking, hygiene sanitation and domestic water supply. The study aims to understand the distribution of ground water quality in solid waste landfill of Bengkulu City. The following objectives of the study are to determine ground water quality parameters such as pH, total dissolved solid, electrical conductivity, hardness, iron, manganese, nitrate and nitrite. Sampling was carried out at a radius of 0 - 250 meters from the location of the landfill. The results of the pH at 10 sampling points show the values that are quite varied between 6,45 – 7,59; conductivity between 56 µS – 492 µS; TDS between 28 mg/L – 246 mg/L; salinity 32 mg/L – 284 mg/L; Iron (Fe) 0,040 mg/L – 0,323 mg/L; Manganese (Mn) 0,089 mg/L – 0,295 mg/L; Nitrate (NO3-) 0,2 mg/L – 0,8 mg/L and Nitrite (NO2-) 0,006 mg/L – 0,033 mg/L. Based on an assessment with the STORET system, water quality in the study area is classified as good (score =-4) by parameters such as temperature, pH, total dissolved solid, electrical conductivity, hardness, iron, manganese, nitrate and nitrite. By the total sampling sites, all sample site had good-quality water for hygiene sanitation based on STORET method.
