Abstract

Lampung Province has a fairly wide swamp area, one of them is in Rawa Pitu area. Swamp irri- gation in Rawa Pitu area has not been used extensively. The purpose of this research is to conduct a study, analysis, and systematically arranged recommendations on revitalizing Rawa Pitu swamp area that can be optimized to increase food crops production in order to improve the welfare of society. The research site is located in the sub-district of Rawa Pitu, Tulang Bawang regency. The location of Rawa Pitu is between the Tulang Bawang and the Pidada rivers. Analysis in this study is more focused on the revitalization of the sub-secondary of swamp irrigation system to increase agricultural productivity in Rawa Pitu area by comparing before and after revitalization. From the calculation, it is obtained that: the maximum of 3 days cumulative daily rainfall with the 5 years return period is obtained 104,12 mm and the amount of drainage modulus is obtained at 4,016 mm / day. Agricultural yield before revitalized, for the rice, the profit is Rp.13.697.819.386,- and for the crops, the profit is Rp.12.452.563.078.-. Agricultural production after revitalized is in- crease, for the rice, the profit is Rp.18.739.594.819,- and for the crops, the profit is Rp.17.035.995.290,-. The value of benefit cost ratio is about 1,38 and it is greater than 1,0, so that there is a profit, and net present value is positive, it is Rp.7.642.988.768,-.

Abstract

Way Rarem irrigation area is focused on improving the productivity of food crops in Lampung. Servicearea of the Regional Irrigation Way raw Rarem estimated at 22,960 hectares. However, in reality thestandard service area for irrigation area is still not achieved. Based on the issues raised above,needed study to find out the problems occur one is to see the relationship of door opening effect to thethe performance of irrigation networks.The results of research in the field indicate that there has been a difference between the dischargemeasurement results with a standard discharge door opening between 0,025 – 0, 206 m3/sec. Thisindicates that a leak in the secondary channel, causing the discharge was not supposed to be deliveredin accordance with the requirements of the land. Loss water are also performed in the secondarybetween BR 32 to BKR 2 canals and water loss by evaporation to pan evaporation test. The resultsshowed the loss of water channels also occur between 0.009 m 3/sec - 0.025 m3/sec. If calculated on apercentage, then the maximum water loss in the secondary channel is 3,27%. Loss of water due toevaporation in the channel is 0,00108 m3/sec/day. If we calculated the economic impact caused of lossof water in the door, then the loss of water amounting to 0,206 m3/sec will make 1,4574 billion IDR.(One billion four hundred and fifty seven million four hundred thousand rupiahs) for the first time thegrowing season. Thus, needed recalibration of the door in the secondary canal as needed accordancewith the plan so that the irrigation network performance can be improved.
