BANDUNG - The Regional Government of West Java Province is building seven reservoirs and dams which are included in the National Strategic Project (PSN). Two reservoirs as Jakarta flood control, five reservoirs as agricultural irrigation.
Two of the capital's flood control reservoirs are located in Bogor Regency, namely the Ciawi Reservoir and Sukamahi Reservoir. The Ciawi Reservoir is designed to have a pool area of ??39.32 hectares with a water capacity of 5.03 million cubic meters. The construction began in 2016 and the physical work has been done around 9.51%.
While the Sukamahi Reservoir is planned to have a pool area of ??49.66 hectares with a water capacity of 1.38 million cubic meters. At present the progress is still at the stage of land acquisition and construction, starting from 2017-2018.
According to the Regional Assistant for Economic Affairs and Development of the Regional Secretariat of West Java Province Eddy Nasution, the two reservoirs will be built in the Ciliwung River basin which is considered to be a frequent source of flooding in the Capital City.
"The Ciliwung River that flows from the tea gardens in Puncak Bogor reaches the DKI area. This is always a problem of flooding, "Eddy said at the Jabar Punya Informasi, at Gedung Sate, Bandung, Thursday (4/4/19).
Five reservoirs that function as agricultural irrigation are located in West Java. Kuningan Reservoir in Kuningan District, Cipanas Reservoir (Sumedang - Indramayu), Sadawarna Reservoir (Subang), Leuwikeris Reservoir (Tasikmalaya Regency), and Matenggeng Reservoir in Pangandaran Regency.
The Kuningan Reservoir is designed to have a pool area of ??221.59 hectares with a water capacity of 25.95 million cubic meters. This reservoir can irrigate 3,000 hectares of paddy fields and supply 500 kilos of electricity. Construction has begun in 2013 and progress has reached 95.77 percent.
The Cipanas reservoir is projected to have a pool area of ??1,444 hectares with a water capacity of 250.81 cubic meters. The reservoir will irrigate 9,243 more hectares and supply 3 mega watts of electricity. At present the progress of construction which began in 2016 has been realized physically 16.66 percent.
The Sadawarna Reservoir will have a pool area of ??498.43 hectares with a water capacity of 43.56 cubic meters. The reservoir is planned to be able to drain 4,500 hectares of irrigation area and supply 3 mega watts of electricity. At present the construction progress is still in the stage of land acquisition.
The Leuwikeris Reservoir was designed to have a pool area of ??242.90 hectares with a capacity of 45.35 cubic meters. The reservoir will be able to irrigate the irrigation area of ??11,216 hectares and supply 3 mega watts of electricity. Construction progress which began in 2016 was 46.85 percent.
While the Matenggeng Reservoir is still in the design review stage. It is planned, in addition to supplying irrigation water and raw water reserves, this reservoir also functions as a flood controller.
Eddy continued, agricultural land cannot only rely on the rainy season. Therefore it is necessary to assist with water from the reservoir. With a reservoir, the planting index increased to three points, aka farmers can harvest rice up to three times a year.
"The benefits of the reservoir on agricultural land are that the reservoir can make us harvest more than twice a year, close to three," he said.
Still at the Japri event, the Head of the West Java Province Water Resources Agency Linda Al Amin explained that all irrigation areas in West Java had been divided based on area and location.
Irrigation areas under 1,000 hectares are under the authority of regencies / cities, while irrigation areas with an area of ??1,000-3,000 hectares are located in cross-regency / municipality areas and become provincial authorities. While the irrigation area above 3,000 hectares is the responsibility of the central government.
Currently West Java has 900,000 hectares of irrigated areas in 103 locations. Around 400,000 hectares are the authority of the central and district / city governments, while 100,000 hectares are managed by the province.
So according to her, the construction of five irrigation reservoirs will have a significant impact on agricultural productivity in West Java.
