Analisa Pengaruh Sudut Putar Rahang Terhadap Kinerja Alat Pengupas Kulit Buah Durian

Abstract

In principle, technology is used by people to ease and improve work efficiency, in terms of both times and production costs sides. A Durian splitter tool applying the jaw rotating method has been created and tested in this study. The focus of the study was the analysis of force in peeling the durians by this tool. The aims of the study were to measure the loads and angles in peeling durian fruits also to calculate the capacity and efficiency of this tool. Then, the testing data retrieval method was putting the load measurement tool on the durian fruit peeler tool and recording the load value obtained during the testing process. The durian fruits were put into the special jaw which can be moved rotate in relative to the knife. The kinds of durian fruits used in the study were ripe and raw fruits. Furthermore, the results obtained were the average force needed in peeling the ripe durian fruits of 99 N by average jaw angle of 45 derajat and the average time of 9.5 seconds. Whereas, the raw durian fruits, the average force needed of 233.38 N by average jaw angle of 80° and the average peeling process time of 15 seconds. The tool capacity of each ripe fruit was 185 fruits/hour and raw fruit was 144 fruits/hour. Thus the tool efficiency of both ripe and raw fruits were the same, namely reach the 85%.
