Analsis Perbaikan Kualitas Crude Palm (CPO) dengan Menggunakan Metode Kaizen di PTPN IV Dolok Sinumbah

Abstract

Kualitas produksi merupakan salah satu indikator penting bagi perusahaan untuk dapat bertahan pada persaingan kualitas. Dalam memenuhi kebutuhan pasar PT. XYZ menghadapi permasalahan dalam pengendalian kualitas produksi yang tidak sesuai standar. Jenis penyimpangan mutu asam lemak bebas tinggi pada PT. XYZ disebabkan tingkat kematangan buah, transportasi dan proses pengolahan. Tujuan dari penelitian ini adalah memberikan usulan perbaikan produksi mutu asam lemak bebas crude palm oil dengan metode Kaizen di PT. XYZ. Identifikasi penyimpangan mutu asam lemak bebas dianalisa menggunakan checkseet, pareto diagram, peta kontrol, fish bond dan FMEA. Didapat hasil bahwa penyimpangan asam lemak bebas terbesar disebabkan oleh keadaan pada buah restan, buah terlalu matang dan buah mentah. Berdasarkan hasil dari nilai RPN sebesar 392 diikuti pemborosan muda dengan nilai 343 dan yang terkecil tingkat kematangan buah dengan nilai 192, sehingga diperoleh kesimpulan berdasarkan analisis dan evaluasi kerusakan asam lemak bebas pada crude palm oil PT. XYZ disebabkan karena faktor manusia, faktor bahan baku, lingkungan, mesin dan metode kerja. Usulan perbaikan berdasarkan Kaizen dibuat dalam bentuk SOP. Production quality is one of the significant indicators for companies to survive in quality competition. In meeting the market needs, PT. XYZ faces problems in controlling production quality that is not up to standard. The deviation type of high free fatty acid quality at PT. XYZ was due to the level of fruit maturity, transportation, and processing. The purpose of this study was to provide suggestions for improving the quality of free fatty acid production of crude palm oil using the Kaizen method at PT. XYZ. The identification of deviations in the quality of free fatty acids was analyzed using a checksheet, Pareto diagram, control chart, fish bond, and FMEA. The results showed that the highest free fatty acid deviation was caused by conditions in Restan fruit (harvested oil palm fruit but not transported to the mill), overripe fruit, and unripe fruit. Based on the results of the RPN value of 392 followed by young waste with a value of 343 and the lowest fruit maturity level with a value of 192, the conclusions were obtained based on the analysis and evaluation of free fatty acid damage in crude palm oil PT XYZ caused by human factors, raw material factors, environment, machines, and work methods. Thus, improvement proposals based on Kaizen were made in the form of SOPs.
