Ergonomic Analysis on Redesigning Rice Harvesting Machines

Abstract

Purposes of Study: Research was conducted with the aim of redesigning and analyzing rice harvesting machines that are in accordance with Indonesian anthropometry, machines that have designs to minimize injuries to the working position of farmers in harvesting rice.
 Methodology: The approach used to complete this research is by method Rapid Upper Limb Assessment (RULA) and Nordic Body Map, RULA considering anthropometric data, energy consumptions. The next step is to implement the calculation of data in the form of rice harvesting machine product design using the product design stages.
 Main Findings: The results of this study indicate that improved rice harvesting machines have better performance than the previous machines. Modification is done by adding two wheels on the front of the rice harvesting machine which can reduce energy expenditure by 2.73 Kcal/minute from 3.82 Kcal/minute to 1.09 Kcal/minute. In terms of productivity, it increased by 22.2% from 9 m2/hour to 11 m2/hour. Other ergonomic parameters using the Nordic Body Map have a significant decrease in pain complaints at 10 points of the limb.
 Implications: Products produced have valuable benefits that can be felt directly by the community with significant results in the process of completing their work.
 Novelty/Originality: The design carried out can provide benefits for traditional farmers who turn to harvest machine technology which can also minimize injury to machine users; this has not been done much research before.

Peningkatan Operasional Mesin Blender pada Produksi Tepung sebagai Upaya Mewujudkan Kemandirian UKM

“…Kebutuhan mesin ini memiliki desain ergonomis, fleksibel dalam operasional kerja karena memiliki 4 roda, pengunci roda dan wadah blender, serta ringkas tidak membutuhkan tempat/ruang produksi yang besar. Ergonomis sendiri memiliki tujuan yaitu: Memaksimalkan efisiensi karyawan, meningkatkan kesehatan dan keselamatan kerja, menganjurkan bekerja dengan aman, nyaman dan penuh semangat, dan memaksimalkan bentuk pekerjaan yang dikerjakan (Nurdin et al, 2020). Konstruksi mesin dibuat sederhana dan ringkas guna memudahkan operasional dalam bekerja, perawatan dan perbaikan cukup dengan satu tenaga kerja.…”
