Abstract

HJ tempeh factory in Ciluar Bogor is a company engaged in the tempeh production industry that produces several variants of tempeh products.  Product variants include tempeh of sizes 18 cm x 30 cm, 18 cm x 25 cm, 20 cm x 25 cm, 17 cm x 25 cm, and mendoan tempeh of size 8 cm x 14 cm. The raw materials used for the production of each variant are soybeans and tempeh yeast. Due to limited raw materials to produce these variants, it is important for the company to determine optimum selling price as well as number of demands in seeking to obtain optimum revenue.
