Abstract
This study aims to design a liquid dish soap made from lerak fruit (Sapindus rarak DC.) as an environmentally friendly alternative to synthetic chemical-based soaps. Lerak fruit was selected due to its high saponin content, which functions as a natural surfactant capable of producing foam and removing grease. This research integrates three courses: Product Design and Development using the Quality Function Deployment (QFD) method with House of Quality (HOQ) to identify consumer needs; Work Measurement Analysis using Operation Process Charts (OPC) to design the production process; and Cost Estimation Analysis using the full costing method to calculate production costs and determine the selling price. Results show that the best product concepts are Concept 4 and Concept 8, characterized by natural lerak surfactant, active ingredient concentration above 15%, pH of approximately 6, citrus/lemon scent, and pump bottle packaging. The production process consists of preparation, mixing, boiling, addition of thickener, cooling, pressing, filtering, and packaging, with a total production time of 142.05 minutes for two 500 ml products. Total production cost is Rp65,184, with a cost of goods sold (COGS) of Rp32,592 per unit and a selling price of Rp34,000 per unit.
