This research concerns on the possibility of separating refined, bleached and deodorised palm oil (RBDPO) into olein and stearin using another alternative through Progressive Freeze Concentration (PFC) to replace the conventional process of dry fractionation. The process was carried out in stainless steel coil crystalliser and the quality of olein and stearin and the performance of crystalliser to purify the olein were analysed. The quality of oil was evaluated through iodine value (IV) and Slip Melting Point (SMP), while for the performance of PFC, effective partition constant, K, and yield of olein were used to determine the system efficiency. The purified olein were obtained for IV and SMP at higher flowrate (2800 mL/min) and longer period of time (60 min) are 55.87wijs and 23.04°C, 55.89wijs and 23.08°C, respectively. Meanwhile, the best K and yield of olein were obtained at higher flowrate and time, giving values of 0.2369, 67.99% and 0.238 and 67.93%, respectively.

This study focused on the possibility of separating refined, bleached and deodorized palm oil (RBDPO) into olein and stearin by using progressive freeze concentration (PFC) as an alternative method to replace the conventional fractionation process. PFC has the potential to be a more effective technique for olein-stearin separation, with minimal changes in the product’s quality for producing high quality edible oil. Apart from that, it requires fewer unit operations compared to conventional methods. In this research, the parameter of coolant temperature was selected to investigate the performance of PFC using stainless steel crystallizer. In order to determine the system efficiency, effective partition constant (K) was investigated, while the quality of the oil was evaluated by iodine value (IV), slip melting point (SMP) and the percentage of olein yield. From the results, all the determinant parameters were found to be optimum at the coolant temperature of 28°C. At this optimum point, K value, IV, SMP and olein yield were found to be 0.2715, 55.84 wijs, 23.10°C and 67.8537%, respectively.

PT. XYZ merupakan perusahaan manufaktur yang bergerak dalam bidang produksi Stainless Steel Coil. PT. XYZ berharap dapat mengurangi pemborosan dalam proses produksinya, sehingga perusahaan dapat mendapatkan laba yang lebih besar dan mampu bersaing di industri saat ini. Tujuan dari penelitian yang dilakukan adalah untuk mengidentifikasi, mereduksi dan memberikan usulan perbaikan terhadap pemborosan (waste) pada proses produksi Stainless Steel Coil. Metode yang digunakan adalah konseplean manufacturing dengan tools value stream mapping dan bantuan metode Failure Mode and Effect Analysis (FMEA). Berdasarkan hasil penelitian pada value stream mapping didapatkan reduksi waktu dari 461 menit atau 27.660 detik menjadi 416 menit atau 24.960 detik. Berdasarkan Failure Mode and Effect Analysis (FMEA) diketahui akar penyebab masalah pada pemborosan (waste) tertinggi adalah Set up hot bucket yang kurang sesuai dan terjadi unplanned downtime atau kurang perawatan mesin. Rekomendasi perbaikan yang dapat diusulkan yaitu pembuatan jadwal pengurasan atau pembersihan hot bucket serta pengetatan terhadap set-up waktu hot bucket dan memperketat jadwal perawatan atau maintainance pada mesin Rolling Mill.

ABSTRACTIndonesia is the world's largest producer of crude palm oil (CPO). Even so, the trend of international trade in Indonesian CPO products has decreased in the last 10 years with a value of -10.19%. The decline in world demand for CPO can be dealt with by utilizing CPO as a biofuel for domestic use, like biodiesel. The purpose of this study is to determine the competitiveness of Indonesian CPO in global trade and determine the parameters of the quality requirements of CPO and biodiesel. The competitiveness analysis method uses the Revealed Comparative Advantage (RCA) method, while the analysis of the potential quality of CPO as a biofuel is carried out by analyzing the Indonesian National Standard (SNI). CPO trade in the global market is controlled by Indonesia with a market share of 50% and Malaysia 25.6%, with the declining trade trend in the last 10 years relatively (2010-2019) of -6.91%. The level of competitiveness of Indonesian CPO products in 2019 is very strong, but on average in the last 10 years, the level of competitiveness of Indonesian CPO is no better than that of Malaysia. Indonesia has SNI 01-2901-2006 and SNI 7182: 2015 as a determinant of the quality of CPO and biodiesel products developed in Indonesia so that the CPO and biodiesel produced fullfil sacurity and safety aspects when used by consumers.Keywords: crude palm oil (CPO), competitivenessv, quality, Indonesian National Standard (SNI) ABSTRAKIndonesia merupakan negara produsen minyak kelapa sawit mentah/ Crude Palm Oil (CPO) terbesar di dunia. Meskipun demikian, tren perdagangan internasional produk CPO Indonesia mengalami penurunan dalam sepuluh tahun terakhir dengan nilai -10,19%. Penurunan permintaan dunia terhadap CPO, dapat disiasati dengan memanfaatkan CPO sebagai bahan bakar nabati untuk keperluan dalam negeri sebagai biodiesel. Tujuan penelitian ini adalah mengetahui daya saing CPO Indonesia dalam perdagangan global dan mengetahui parameter persyaratan mutu CPO dan biodiesel. Metode analisis daya saing menggunakan metode Revealed Comparative Advantage (RCA), sedangkan analisis potensi kualitas CPO sebagai biofuel dilakukan dengan menganalisis Standar Nasional Indoensia (SNI). Perdagangan CPO dalam pasar global dikuasai oleh Indonesia dengan pangsa pasar 50% dan Malaysia 25,6%, dengan tren perdagangan relatif menurun dalam 10 tahun terakhir (2010-2019) sebesar -6,91%. Tingkat daya saing produk CPO Indonesia pada tahun 2019 sangat kuat, namun secara rata-rata dalam 10 tahun terakhir, tingkat daya saing CPO Indonesia tidak lebih baik dari Malaysia. Indonesia memiliki SNI 01-2901-2006 dan SNI 7182:2015 sebagai penentu kualitas produk CPO dan biodiesel yang dikembangkan di Indonesia, sehingga CPO dan biodiesel yang dihasilkan memenuhi aspek keamanan dan keselamatan ketika digunakan oleh konsumen.Kata kunci: crude palm oil (CPO), daya saing, kualitas, Standar Nasional Indonesia (SNI)
