Analisis Kadar Air dan Kadar Asam Lemak Bebas (ALB) pada Crude Palm Oil (CPO) dari Tangki Timbun di PT. Kharisma Pemasaran Bersama Nusantara (KPBN) Belawan

Abstract

The research carried out aimed to determine the quality of CPO (Crude Palm Oil) at PT Kharisma Marketing Bersama Nusantara (KPBN) Belawan Unit based on chemical parameters. The chemical parameters explained in this research are air content analysis and free fatty acid (ALB) analysis. Air content analysis begins by inserting the frying pan sample into the moisture analyzer, then adding 5 grams of CPO sample to the frying pan sample, waiting until the tool beeps indicating the air content is constant. In the free fatty acid level analyzer, start by weighing an empty Erlenmeyer flask then set to 0, then weigh ±3 grams of CPO, then add 50 mL of alcohol, then add 2-3 drops of 1% phenolpthalein indicator, then titrate with 0.0898 KOH solution. Which is marked by a change in orange color and the results are recorded. From the measurement results, calculations were then carried out on samples T34, T64 and T43 so that the results obtained for analyzing the air content at PT KPBN were 0.26%, 0.24% and 0.24%, and the free fatty acid content at PT KPBN was 3 .81%, 3.02%, and 3.56%,. In accordance with SNI 01- 2901-2021 concerning Crude Palm Oil, the water content is 0.25-0.50% and the free fatty acid content is 3.0-5.0%. From the results of these calculations, the water content of the three samples has met SNI quality standards.
