Abstract

ABSTRACT  The watersheds is an ecosystem and the main elements of this ecosystem are natural resources (land, water and vegetation) and human resources that utilize natural resources. Regarding with the relationship between watershed and irrigation as one component in the water resources management, watersheds determine the availability of irrigation water when the watershed ecosystem is disrupted. In this condition, the water supply for irrigation decreased and therefore the agricultural productivity reduced. The area of the Lelema Watershed is 3,095 ha with a main river as long as 12,787 m that ends in the main river of Nimanga. The irrigated area of the Popontolen village is geographically located in the irrigation area  of Popontolen Village that is located at 1o15'47 "- 1o16'40" LU and 124o36'20 "- 124o38'00" BT. The area of Popontolen irrigation is 121.20 ha and consisted of primary, secondary and tertiary channels. In conclusion, the carrying channel in the irrigation area of the Popontolen Village is 7,468 meters and the length of primary and secondary carrier channels are 213 and 3,131 m, respectively.  Keywords: Lelema Watershed, Technical Irrigation, Geographic Information System.

Abstract

AbstractCombine harvester Maxxi Corn Type-G Automatic, is a combination of three different operations, arice harvesting machine that can cut the standing grain, thresh and clean the grain while walking in the field,thereby shortening the harvesting time. However, until now there has been no study on the performance ofharvesting capacity, harvesting efficiency and threshing of the Combine Harvester Maxxi Corn Type-GAutomatic in Tababo Village. The purpose of this study was to test the performance of the Combine HarvesterMaxxi Corn Type-G Automatic which is used to harvest rice in Tababo Village which includes, harvestingfield capacity, field efficiency, and threshing capacity. The research method used experimental methods indata collection then all the data obtained were made in the form of tables and graphs and then processeddescriptively. This research uses a Combine Harvester Maxxi Corn Machine Type-G Automatic and a lengthmeasuring device (50 m tape meter), a time measuring device (stopwatch), a scale, a tachometer, a grainmoisture meter, as well as plastic sacks and rice paddies ready to harvest the Adirasa Six Empat variety. witha harvest age of 75 to 80 days and a spacing of 25 x 25 cm on a land size of 15 x 15 m.The performance of theMaxxi Corn Type-G Automatic Combine Harvester in the field produces a theoretical field capacity of 0.3654ha/hour, an effective field capacity of 0.1844 ha/hour and a harvesting field efficiency of 50.6214% and athreshing capacity of 432.54 kg/hour.Keywords:Performance Test Of Machine Combine Harvester Maxxi Corn Tipe-G Automatic
