The objective of this study is to produce a biodegradable plastic sheet from mung bean starch used cooking oil. This methodology aims to minimize the environmental impact of waste frying oil and plastic, which are two serious sources of terrestrial and aquatic pollution, as well as waste management problems for the food and environmental industry. The series of operations include extracting starch, forming the bioplastic and packing the end product. The mung bean-based bioplastic made use of mung bean starch, coconut and palm oil, glycerol, sorbitol, citric acid, soy lecithin. Various analysis were conducted to ascertain that the material could serve as a substitute to biopolymer plastic introduced into the market, including microbial analysis to total plate count by pour plate CCU/g (1.10), pH test; the tensile strength result was obtained as 6.0 MPa, soil burial test revealed the structural driven weakening of the material integrity and almost full decomposition on the final day, Barrier property near zero (oxygen permeability) by gravimetric method and moisture permeability obtained 6.12 using desiccant method both passed based on standard. To make the end product biodegradable, he used an environmentally friendly packaging material (bioplastic sheet primary packaging, kraft board primary secondary
packaging). Moreover, the product was evaluated with a TUP prototype using a likert- scale to measure its features. This review reported a mean score of 4.25, which represents
a very good acceptability. In this way, BSP described here was also good in properties such as a gloss, touch, durability, and other properties.
