Rancang Bangun Mesin Perajang Singkong Menggunakan Daya 200 Watt Kapasitas 40 Km/Jam

Abstract

This study aims to determine the design of a 200-watt cassava grinding machine with a capacity of 40 kg/h, as well as to define its specifications. The design of this machine is carried out in several stages: needs analysis, project definition, development of technical specifications, concept planning, product design, and preparation of manufacturing documents. The next stage consists of analyzing the needs while taking into account constraints and planning requirements.

The results of the machine design are as follows: (1) Design of a high-performance cassava grinding machine; (2) Transmission system allowing the rotational speed of the electric motor to be varied from 2,727.6 rpm to 859.6 rpm using two pulleys with diameters of 5 cm and 16 cm respectively, connected by an A-37 V-belt. The shaft used has a diameter of 18 mm and is made of ST 50 material; (3) The design of this cassava chopping machine requires the power of a 1/4 HP electric motor; (4) The performance test of the cassava grating machine is capable of producing 40 kg/hour of cassava grated cassava.
