Abstract

This study aims to analyze the effectiveness of the use of silica sand (SiO₂) as a filtration medium in the water treatment system at the PT. Star Bahal Palm Oil Mill. The method used is quantitative descriptive by testing water quality parameters before and after filtration, including turbidity, acidity (pH), and iron content (Fe). Data collection was carried out nine times in the period from December 2025 to January 2026. The results showed that filtration using silica sand was able to reduce water turbidity from an average of 13 FAU to 0 FAU (100% efficiency), reduce Fe levels from 0.4 mg/L to 0.044 mg/L (89% efficiency), and increase pH from 5.99 to 7.00. These results show that silica media is effective in improving water quality physically and chemically. The novelty of this research lies in the evaluation of silica filtration performance based on real operational data in the palm oil industry with quantitative efficiency analysis. The results of this study are expected to be a reference in the development of efficient and applicable water treatment systems in the industrial sector.

Keywords: silica, water filtration, water treatment.
