Application of KUBOTA DC-60 for Paddy wet Field Harvesting

Abstract

Rice was still be main foodstuffs for Indonesian people. Method of paddy wet field harvesting could be done manually utilized sickle or mechanically utilized KUBOTA DC-60 combine harvester. Some problems often occured during paddy harvesting and threshing such as harvesting and threshing losses, and low harvesting and threshing capacities. The objectives of the research was to compare harvesting and threshing results utilized sickle and power thresher with harvesting results utilized KUBOTA DC-60 combine harvester. The research was held on March 2013 until May 2013 in Sukamandi, Subang, West Java. Paddy with Ciherang variety was harvested manually utilized sickle and then it was threshed utilized power thresher, and it was harvested mechanically utilized KUBOTA DC-60 combine harvester. Yield losses of harvesting and threshing, capacities of harvesting and threshing, and field capacities of harvesting and threshing were measured. Results of the research showed that yield losses of harvesting and threshing, capacities of harvesting and threshing, and field capacities of harvesting and threshing utilized sickle and power thresher were 46.1%,18.39%,0.19 ton/person.hour, 1.60 ton/hour, 0.006 halperson.hour, and 0.28 halhour respectively. Yield loss of harvesting, harvesting capacity, and harvesting field capacity utilized KUBOTA DC-60 combine harvester were 2.73%, 1.56 tonlhour, and 0.49 halhour respectively. Yield losses utilized sickle and power thresher were higher than yield loss utilized KUBOTA DC-60, whereas harvesting capacity utilized sickle was lower than harvesting capacity utilized KUBOTA DC-60, so that paddy wet field harvesting utilized KUBOTA DC-60 was more effective and more efficient than harvesting utilized sickle and threshing utilized power thresher.
