Abstract
Gliserol Monostearat (GMS) merupakan salah satu jenis surfaktan yang banyak diaplikasikan dalam industri kue. Selain itu, GMS juga banyak digunakan pada industri makanan sebagai thickener, preservative agent, emulsifying agent untuk makanan dan oil, waxes, dan solvent pada industri farmasi dan kosmetik, dan juga banyak digunakan dalam industri polimer yaitu plastik, karet dan juga bahan pembuatan ban. Namun, banyaknya kebutuhan gliserol monostearat di Indonesia tidak didukung dengan pasokan gliserol monostearat yang mencukupi sehingga harus mengimpor seluruh kebutuhan dalam jumlah besar. Dari data Badan Pusat Statistik Indonesia, diketahui data impor GMS untuk Indonesia dari tahun 2015 hingga 2019 mengalami peningkatan sebesar 0,032%/tahun, dimana pada tahun 2019 jumlah impor GMS sebesar 5.966.300 kg.
Proses pembuatan gliserol monostearat pada pabrik ini memiliki beberapa tahap: tahap persiapan bahan baku, tahap reaksi, tahap solidifikasi, tahap pemisahan, dan terakhir tahap pengeringan dan packaging. Pabrik ini berlokasi di Kaltim Industrial Estate, Kalimantan Timur, dengan bahan baku yang diperoleh yaitu gliserol dari PT. Smart Tbk, asam stearat dari PT. Smart Tbk, asam fosfat dari PT. Pupuk Kaltim, dan natrium hidroksida dari PT. Asahimas Chemical. Pabrik direncanakan memiliki kapasitas 10.000 ton/tahun. Sehingga hasil pabrik ini dapat memenuhi kebutuhan gliserol monostearat dalam negeri. Pendirian pabrik ini menggunakan data investasi yang berasal dari modal sendiri sebesar 40% dan modal pinjaman sebesar 60% dari biaya investasi dengan bunga 9,8%. Dari Analisa ekonomi, didapatkan hasil investasi sebesar Rp 438.556.413.799,66, IRR 18,68%, POT 4,28 tahun, BEP 73,16% dan waktu konstruksi selama 24 bulan. Berdasarkan analisa BEP, POT, dan IRR, pabrik Gliserol Monostearat ini layak untuk didirikan.
================================================================================================
Glycerol Monostearate (GMS) is a type of surfactant that is widely applied in the baking industry. In addition, GMS is also widely used in the food industry as a thickener, preservative agent, emulsifying agent for food and oil, waxes, and solvents in the pharmaceutical and cosmetic industries, and widely used in the polymer industry, namely plastics, rubber and tire manufacturing materials. However, the large demand for glycerol monostearate in Indonesia is not supported by an adequate supply of glycerol monostearate, so it needs to import GMS in large quantities. Based on Indonesian Central Bureau of Statistics data, it is known that GMS import data for Indonesia from 2015 to 2019 has increased by 0,032% / year, where in 2019 the number of GMS imports was 5.966.300 kg.
The process of making glycerol monostearate or GMS is divided into several stages such as pre-treatment process, reaction process, solidification process, separation process, and drying and packaging process. This factory is located in Kaltim Industrial Estate, East Kalimantan, with the raw material, namely glycerol from PT. Smart Tbk, stearic acid from PT. Smart Tbk, phosphoric acid from PT. Pupuk Kaltim, and sodium hydroxide from PT. Asahimas Chemical. The plant is planned to have a capacity of 10.000 tons/year. This capacity can meet the domestic demand for glycerol monostearate. The establishment of this factory uses investment data that comes from individual capital at 40% and loan capital at 60% of the investment cost with an interest of 9,8%. From the economic analysis, the investment yields were 438.556.413.799,66, , IRR 18,68%, POT 4,28 years, BEP 73,16% and a period of construction for 24 months. Based on the analysis of BEP, POT, and IRR, this Glycerol Monostearate factory is feasible to be established.
