Prarancangan Pabrik Pembuatan Bijih Bioplastik Berbahan Dasar Pati Ubi Jalar Termodifikasi Proses Asetilasi dengan Penambahan Asam Sitrat sebagai Crosslink Agent dengan Kapasitas 37.500 Ton/tahun

Abstract

Bioplastic pellets are an environmentally friendly alternative to conventional plastics derived from renewable raw materials. The main objective of this plant design is to implement the principles of chemical engineering and to provide preliminary information for the establishment of a bioplastic pellet manufacturing plant from sweet potatoes through an acetylation process with a production capacity of 37,500 tons per year. The main process in this preliminary plant design consists of three stages: raw material preparation, product formation, and product purification. The plant is planned to be established in Winduherang Village, Cigugur District, Kuningan Regency, West Java Province, with a land area of 19,200 m². The plant will employ 120 workers and operate as a Limited Liability Company (PT) led by a director with a line organizational system. The total investment required for the establishment and operation of the plant is Rp 4.275.833.673.631, with a production cost of Rp 2.587.818.528.449. Based on the feasibility analysis, the plant shows a Break-Even Point (BEP) of 21.35%, a Return on Investment (ROI) of 12,26%, a Pay Out Time (POT) of 8 years and 2 months, a Rate of Return on Net Worth (RON) of 20,44%, and an Internal Rate of Return (IRR) of 16%. From the economic analysis results, it can be concluded that this preliminary design for a bioplastic pellet manufacturing plant is economically feasible to establish.
