PENGEMBANGAN SISTEM PENGGERAK MESIN PEMERAS SERBAGUNA MENGGUNAKAN METODE REVERSE ENGINEERING BERBASIS SIMULASI MENGGUNAKAN SOFTWARE FUSION

Abstract

The large customer demand for herbal medicine makes herbal medicine companies feel helped by the presence of a spice extracting technology (ginger, turmeric, temulawak) that is able to squeeze quickly and without experiencing significant fatigue. So far, one of the herbal medicine producers in Sidoarjo uses a multipurpose squeezer machine with the Pressmach T30H brand with a capacity of 5 kg/batch. Based on the results of discussions with herbal medicine manufacturers, users feel that the driving force used is still relatively large, namely HP (372 W). According to this suggestion, the researcher will make efforts to reduce the power in the drive system with the consequence that the squeeze function must continue to work optimally. From the previous results optimal squeeze using a compressive force of 150 Kgf. To solve this problem, the researcher uses the reverse engineering method. In using this method, the researcher must make repeated observations, especially on the drive system, including 1) recalculation of the power requirements, 2) the selection of the driving motor, 3) the transmission system. Based on the results of the study, it was found that the power needed to suppress 150 kgf is 6.39 watts, the installed motor power is 18.63 watts and the motor available on the market is closest to 25 watts. The selection of motors in the market is carried out based on several criteria, including (Mott et al., 2018:725): a) DC or AC type motor, b) Power and speed, c) Voltage, d) Shell type, e) Frame type, f) Motor size, g) Price and set 4IK25GN AC motor as the driver. The reverse engineered engine uses a sprocket and chain transmission system with a ratio of 1: 1.38 and uses a drive system arrangement starting from the motor - sprocket and chain - jack shaft - screw jack - pressure plate.
