Prarancangan Pabrik Pembuatan Biji Bioplastik Berbahan Dasar Pati Sagu Termodifikasi Asetilasi dengan Penambahan Ekstrak Daun Sirih (Piper Betle L.) dengan Kapasitas 1200 Ton/Tahun

Abstract

The bioplastic pellet is produced using sago starch as the main raw material because sago starch is easily degraded by nature due to its amylopectin content, which exhibits polymeric properties suitable for plastic formation. The addition of betel leaf extract serves as an antibacterial agent in the bioplastic to protect the wrapped materials from microorganisms, aided by tannins that possess antibacterial properties. The preliminary design study focuses on a bioplastic pellet manufacturing plant using acetylated modified sago starch with the addition of betel leaf extract (Piper betle L.), with a production capacity of 1,200 tons per year, operating 330 days annually. The plant is planned to be located in the Belawan Industrial Area, North Sumatra. The purpose of this preliminary design is to apply chemical engineering principles, including mass balance, energy balance, equipment specifications, chemical engineering operations, process design, utility systems, and other relevant aspects of chemical engineering. The economic evaluation results for the bioplastic pellet manufacturing plant using acetylated modified sago starch with the addition of betel leaf extract are as follows: Total capital investment : Rp 316.124.066.000,20 Production cost : Rp 114.280.480.039,11 Sales revenue : Rp 187.737.840.850,85 Net profit : Rp 45.664.920.301,25 Profit margin : 37,17% Break even point : 44,27% Return on investment : 14,45% Pay out time : 7 Tahun Return on network : 26,26% Internal rate of return : 12,04% Based on the economic analysis, it is concluded that the establishment of a bioplastic pellet manufacturing plant using acetylated modified sago starch with the addition of betel leaf extract is considered feasible.
