DESIGNING FOOD DELIVERY MACHINE FOR POULTRY IN CHICKEN FARM TO REDUCE EMPLOYEE UNERGONOMIC MOTION AT MIJEN'S CHICKEN FARM

Abstract

At Mijen's Chicken Farm, feeding is still performed manually. There were four workers performing the jobs in the three level of stall, and carries a sack of chicken food for 50 Kg, two hours daily. The manual process resulted ergonomically an unsafe working position with a REBA score between 11 and 15 and high level of risk, indicating that immediate action is necessary. To eliminate or reduce the unsafe working condition, a food delivery machine capable of rectifying the situation was proposed. This machine's design incorporates QFD to accommodate user requirements and value engineering to produce the most cost-effective tool. The results of the identification revealed a number of usability, security, comfort, strength, accuracy, efficiency, anti-rust, and durability characteristics. In addition, value engineering is utilized in the development of the tool's 12 material concepts. The selection of a concept is determined by considering its function and cost. Concept 8 was selected with a value of 1.8730, its total cost was Rp 3,707,347, and its function was 3,194. The results of the design can reduce the number of workers from four to two and reduce the REBA score from 11-15 into 4 and 5 indicating medium risk, as humans are replaced by machines, saving Rp 5,670,042 in labor costs and incurring an operating cost of Rp.130,023 per month for 3000 watts of electricity for this machine.
