Abstract
ABSTRAK
RBD Oils kepanjangan dari Refined, Bleached, Deodorized. RBD merupakan salah satu komoditas ekspor Indonesia yang permintaannya cukup besar. Pada umumnya, proses pembuatan minyak kelapa RBD menggunakan kopra sebagai bahan baku. Minyak kelapa yang terbuat dari kopra masih memiliki kandungan asam lemak yang cukup tinggi sehingga tidak dapat dikonsumsi secara langsung. Minyak kelapa yang dihasilkan dari kopra masih memiliki kandungan asam lemak bebas (FFA) yang relatif tinggi (antara 3-5%) akibat hidrolisis enzimatik, sehingga perlu dilakukan pemurnian lebih lanjut, antara lain: pemurnian, pemutihan, dan penghilangan bau, agar minyak kelapa dapat dikonsumsi. FFA mengalir melalui uap dalam kondisi vakum dan suhu tinggi tanpa menggunakan netralisasi basa. Produk atas adalah Coconut Fatty Acid Distillate (CFAD) dan produk bawah adalah minyak kelapa RBD Coconut Oil yang merupakan produk utama. Oleh karena itu, penelitian ini berfokus pada bagaimana memisahkan asam lemak minyak kelapa menggunakan simulasi aspen hysys. Hasil dari penelitian ini didapatkan bahwa semakin banyak jumlah tray, flow rate steam input dan semakin besar tekanan vacuum yang diberikan pada kolom deodorize, maka semakin sedikit kandungan FFA pada produk RBD coconut oil yang dihasilkan. Untuk memproduksi RBD Coconut Oil dengan kualitas FFA 0.085% hingga 0.089%. Dilakukan penambahan jumlah tray dari 33 stages menjadi 55 stages dan tekanan vacum dari 5 kPa menjadi 4 kPa dapat menggurangi beban produksi sebesar 32.54%

ABSTRACT
RBD coconut oil is one of Indonesia's export commodities, which is in high demand. In general, the process of making RBD coconut oil uses copra as raw material. Coconut oil made from copra still has a high fatty acid content so it cannot be consumed directly. Coconut oil produced from copra still has a relatively high free fatty acid (FFA) content (between 3-5%) due to enzymatic hydrolysis, so further purification, including refining, bleaching, and deodorising, is necessary to make coconut oil consumable. FFAs flow through steam under vacuum and high temperature conditions without the use of base neutralisation. The top product is Coconut Fatty Acid Distillate (CFAD), and the bottom product is RBD Coconut Oil which is the main product. Therefore, this research focuses on how to separate coconut oil fatty acids using aspen hysys simulation. The results of this study found that the more the number of trays, the flow rate of steam input and the greater the vacuum pressure applied to the deodorize column, the less FFA content in the resulting RBD coconut oil product. To produce RBD Coconut Oil with FFA quality of 0.085% to 0.089%. Increasing the number of trays from 33 stages to 55 stages and vacuum pressure from 5 kPa to 4 kPa can reduce the production load as much as 0.089%.
