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

The purpose of this study is analyze the correlation of accessibility to the level of mobility and the correlation of mobility to socio-economic in Tanjung Karang Pusat sub-district. The sample targets are the people in Tanjung Karang Pusat sub-district as well as from the competent parties in their field, using the random sampling technique. Data collection is done through questioner with descriptive analysis method and PSPP analysis. Based on the calculation of IRI (index of road infrastructure) value in Tanjung Karang Pusat sub district, which is 5.74, the value almost meets the national minimum value requirement, which is 6. For accessibility index is 22,289 larger than MSS (>5,0) while for mobility index has a value of 1.355 smaller than MSS (minimum service standard) requirements that have been set which is > 2.0. The level of mobility is strongly influenced by the regional income itself. One way to increase the IRI value is by adding a road network. The writer took Durian Payung urban village which has a lot of vacant land area, which is increase 3.91 km and able to raise IRI to become 6,01 and exceed national minimum value. In correlating the mobility with the socioeconomic obtained the equation f(x) = 2,71+0,25X1+0,04X2+0,12X3+0,14X4 based on T-test the influential value is income. Correlation of accesability with mobility obtained the equation f(x) = 1,64+0,004X1+0,37X2+0,0002X3 based on T-test the influential value is travel destination . Correlation of accesability and socioeconomic with mobility obtained the equation f(x) = 2,12+0,11X1+0,03X2 based on T-test the influential value is accesability. Key words: Accesability, Mobility, Socioeconomic, Tanjung Karang Pusat
