Perancangan Model Faktor Ergonomi Makro Terhadap Produktivitas Sistem Kerja pada Pabrik Gula

Abstract

Sugar mill is a part of sugar industry representing a dynamic work system which occupies machine and human labour. The good scheme ergonomic covers the micro and macro ergonomics to improve productivity of work system. This research was conducted in order to learn and determine the macro and micro parameter of ergonomics at the work system in a sugar mill. The determination of these parameters was applied in model scheme of micro and macro ergonomic factors to improve work system productivity. The illumination, temperature, humidity, noise, vibration, and operator perceptions ware collected as data input for modelling system using artificial neural network. As the result, the optimum productivity level in PG Bungamayang can be reached if the combination of macro and micro ergonomic factors for the illumination 100-200 lux, temperature 25 0C, humidity 60-70%, noise 85 dB, vibration 1.6-2 m/s2 and very care to organizational work system of the operator perception level with the predicted productivity level equals to 1858-1865 ton cane/shift, and in PG Jatitujuh can be reached if illumination 220-260 lux, temperature 28-29 0C, humidity 62-66%, noise 80 dB, vibration 1.2-1.6 m/s2 and very care to organizational work system of the operator perception level, with the predicted productivity level equals to 1464-1592 ton cane / shift.
