IMPLEMENTASI MOTOR SERVO SEBAGAI KONTROL VALVE PADA ALAT PENGISIAN GULA CURAH KILOAN

Abstract

Granulated sugar is a basic necessity for many Indonesians. It’s commonly sold in two types of packaging: branded and unbranded. Most lower-income households prefer unbranded sugar because it’s more affordable. Typically, producers distribute it in 50 kg sacks, and local retailers then sell it in smaller portions like 250g, 500g, 1kg, and 2kg. However, many vendors still rely on manual scales, which are less efficient and require constant adjustments to ensure accuracy. To solve this problem, this final project introduces an automatic bulk sugar dispenser using a servo motor and a load cell sensor. The system automatically controls a valve that opens when the sugar weight is below the target and closes when the desired weight is reached. By integrating a servo motor, the device improves the accuracy and efficiency of sugar packaging, making the process quicker and more practical. Integration testing confirmed that all components worked as intended. The system dispenses sugar precisely, the power supply meets the requirements, and the load cellprovides accurate readings. Ten test samples showed average weight errors of just 0.84% (250g), 0.54% (500g), 0.26% (1kg), and 0.35% (2kg).
