Preliminary Field and Costs Evaluation of a New Mechanised System for Holing Soil in Large Polybag in Oil Palm Nursery

Abstract

A preliminary field and costs evaluation was conducted to evaluate the performance of a newly developed during the preliminary field and costs evaluation included production capacity, mean increase in heart about 257 bags hr -1 increase as compared to 83 bags hr -1 per man with the current practice. Mean increase in heart rate of worker when operating the machine systems was 24.2 beats min -1 beats min -1 consumed 3.16 kcal min -1 -1 per man -1 cheaper as compared to RM 0.07 bag -1 with the current practice. ROI of the new machine system was
