Rancang Bangun Mesin Pengaduk Nira Nipah Kapasitas 30 Liter

Bengkalis Regency, particularly Pambang Baru Village in Bantan District, has abundant nipa sap potential that can be processed into high-value palm sugar. However, the traditional mixing process results in inconsistent product quality and increases ergonomic risks for workers.This design produces a 30-liter capacity nipa sap stirring machine equipped with a Belt and Pulley transmission system driven by a 1 HP electric motor, combined with a V-Belt and Gearbox to deliver low rotational speed with high torque. The Belt and Pulley transmission was selected for its advantages, including ease of maintenance, low manufacturing cost, good vibration damping, and flexibility in adjusting the speed ratio.Testing showed that the electric-motor-driven machine, operating at a shaft speed of 29.3 rpm, produced approximately 5.4 kg of evenly textured palm sugar, although the hardening time was slightly longer. In comparison, the combustion-engine-driven machine produced approximately 5.2 kg with faster hardening, but part of the product did not solidify completely and tended to melt at room temperature.The results demonstrate that the electric-motor-driven stirring machine with a Belt and Pulley transmission can improve product quality and consistency while reducing manual workload and supporting the sustainability of palm sugar MSMEs in coastal areas.
