Abstract

One of the first steps in processing river water into drinking water is by removing the turbidity of the river water. Turbidity can be removed by adding a chemical called a coagulant. This study aims to obtain data on how the effect of using coagulant dosage variations in reducing turbidity and iron content in raw water at the water treatment plant (IPA) PDAM X. The study was conducted using the jar test method to determine the dose of aluminum sulfate coagulant in reducing turbidity and colorimetric method using visible spectrophotometry to determine iron content that meets quality standard criteria. The results showed that the higher the coagulant dose, the lower the turbidity and iron content of the raw water. Coagulant doses with up to 30 ppm were able to reduce turbidity with an efficiency of 92.67% and reduce iron levels up 96.10%.

Abstract

Biooil is a liquid obtained from cracking lignocellulose structures into simpler compounds from the pyrolysis process. The lignocellulose content in palm midrib can be used as a raw material for making biooil. This study examines the effect of the length of time burning at a temperature of 250 ℃ on the physical and chemical characteristics of the resulting biooil. The independent variable was pyrolysis time with 1 hour, 2 hours, and 3 hours. The parameters used to determine the quality of biooil are specific gravity, pH, color, and composition of biooil by GC-MS instrument. From the results obtained, the highest yield of biooil was 7.9945% from sample with 2 hours pyrolysis time. The quality of biooil showed the average pH ranged between 2.65–3.08 and the average density ranged from 1.0485 to 1.1055. The visual of biooil was dark brown color with the largest biooil content being Cis-Vaccenic acid.
