Analisis Asam Lemak Bebas dan Bilangan Yodium dari Refined, Bleached, Deodorized Palm Kernel Stearin (RBDPKS) di Laboratorium Bea dan Cukai Kelas II Medan

Abstract

Testing for free fatty acids and iodine value in Refined Bleached Deodorized Palm Kernel Stearin (RBDPKS) at the Medan Class II Customs Laboratory has been carried out with the aim of determining whether the ALB content and iodine value in RBDPKS are in accordance with the quality standards of PERMENDAG No.54. TheALB test was carried out using the alkalimetric titration method and the iodine number using the iodometric titration method. The test was carried out with 3 samples, and the average value of ALB on RBDPKS was obtained, namely: RBDPKS1 = 0.075%, RBDPKS2 = 0.065%, RBDPKS3 = 0.087%. In iodine numbers with average values: RBDPKS1 = 7.86 g, RBDPKS2 = 5.33 g, RBDPKS3 = 5.84 g. The analysis results show that the RBDPKS has met the standards of PERMENDAG No. 54 which has been determined is for ALB <2% and Iodine Number 5-8 gI2/ 100 g.
