Penetuan Kadar Air dan Asam Lemak Bebas (ALB) Crude Palm Oil (CPO) dengan Metode Titrasi Alkalimetri PT. SDS di Laboratorium Kharisma Pemasaran Bersama Nusantara (KPBN) Belawan

Abstract

The research conducted aims to determine the water content and free fatty acids of Crude Palm Oil (CPO) using the alkalimetry titration method PT. SDS based on chemical parameters. The chemical parameters analyzed in this study are water content analysis and free fatty acid (ALB) analysis. Water content analysis, starting with inserting the sample pan into the moisture analyzer, then adding a CPO sample of 5 grams into the sample pan, waiting until the device sounds indicating a constant water content. The analysis of free fatty acid levels begins with weighing empty Erlenmeyer then at 0 kan, weighing CPO as much as 3 grams, then adding 50mL alcohol, then adding 2-3 drops of 1% phenolphthalein indicator, then titrated with 0.0898N. KOH solution which is characterized by an orange color change and recorded the results. From the measurement results, calculations were then carried out on samples A, B, and C so that the results for moisture content analysis were obtained which were 0.28% for sample A, 0.26% for sample B, and 0.27% for sample C. Free fatty acid levels were 3.82% for sample A, 4.88% for sample B, and 3.86% for sample C. By SNI 01-2901-2021 concerning Crude Palm Oil for water content of 0.25-0.50% and free fatty acid content, namely 3,0-5,0 %. From the results of these calculations, the water content and free fatty acid levels have met SNI quality standards
