Pra Rancangan Pabrik Pembuatan Microcrystal Cellulose (MCC) dari Sabut Kelapa melalui Proses Ekstruksi Reaktif dengan Kapasitas 5.000 Ton/Tahun

Abstract

Microcrystal Cellulose (MCC) is isolated from alpha cellulose, which is pure cellulosa-producing porous particle powder and has properties that are insoluble in water but can float when exposed to water. MCC is a material that can be used in the pharmaceutical industry, namely as a filler, in the food industry as a fat source material, in the plastic industry as a composite manufacturing material, and can also be applied in the cosmetic industry. In the pre-planning of this plant, MCC is made from raw materials that have a high cellulose content and are widely available in Indonesia. One of the raw materials that can be used is coconut husks with a cellulose content of 43.44%. The MCC plant is planned to produce 5,000 tons per year and operate for 330 days in a year. In the preliminary design of this MCC plant, we will use a reactive extraction process. Reactive extraction is the process of combining friction, pressure, and heat. The tool that will be used in this selective extraction process is an extruder with a single screw extrude type. The extruder will rotate, which can generate pressure and temperature. By applying pressure to the extruder, it will create strong friction and produce a shorter reaction time. The main process in the MCC plant pre-design consists of two main processes and one bleaching process, namely: 1. The process of delignification of lignin into na-lignate 2. Process of hydrolysis of cellulose into MCC 3. The process of bleaching using H2O2 The design of the main process tool is based on the pre-project MCC factory manufacturing with coconut rope raw materials through a reactive extraction process, those are: 1. Delignification.Reactions • Catalytic used : NaOH 17.5% • Temperature : 90°C • Pressure : 1 atm • Time : 1 hour 2. Hydrolysis reactions • Catalytic used : HCl 5% • Temperature : 140 °C • Pressure : 1 Atm This plant is planned to be established in Indragiri Hilir district, Riau Province, with an area of 15,756 m2. The workforce needed as many as 200 people with a limited company (PT) under the leadership of a chief executive officer. The results of the economic evaluation of the MCC Manufacturing Factory for this coconut strap are as follows: a. Capital Investment (CI) = Rp 535.260.154.908 b. Total Cost (TC) = Rp 234.639.377.945 c. Profit Margin (PM) = 50,42% d. Break Even Point (BEP) = 44,55% e. Return on Investment (ROI) = 30,67% f. Return On Network (RON) = 51,12% g. Pay Out Time (POT) = 3 tahun 2 bulan h. Internal Rate of Return (IRR) = 56,00% From the results of the economic evaluation, it can be concluded that the manufacturing factory for microcrystal cellulose is worthy of being established.
