| description | Ogan Komering Ulu Eastern District with an area of 3370 km2 area has
76,888 ha of paddy fields and irrigation water that could land area of 45,904 ha.
The main river is the River Komering. Along the river there are many settlements.
At first the water source for DI. Komeringg taken from Komering River
downstream through the decision-free (free intake) Lives cage was built in 1937
since the Dutch era. Over time, conditions and river morphology Komering
undergone many changes that cause the function of the building free intake cage
Lives experiencing problems due to high sedimentation so it does not ensure the
continuity of provision of irrigation water. In 1990 a dam was built Perjaya so IN.
Komering can be irrigated. In DI water needs. Komering not be met in the dry
season the dam Perjaya. This is due to the availability of a little water so that the
discharge is available is relatively small. To solve the above problems, it would
require optimization of water allocation for irrigation Komering land potential in
its service area and can be optimized to provide maximum benefits.
This study airms to get the total value of the maximum profit by
optimizing the alocation of irrigation water the use of debit and land mainstay in
the field. The results are expected to provide and optimal solution acreage by type
of commodity crops based on need and availability of water and can provide
input to decision-makers rearding the management of water resources for
Komering River Irrigation Area Komering. Optimization analysis performed
using a linear program (Lindo version 6.1) which in terms of technical and
ecomoic aspects based irrgation management polcy reform.
The results showed that the optimum planting area and the maximum
profit earned is determined by the availability of the allocated discharge. For the
allocation of discharge mainstay of Q = 100% gives the optimum acreage of
122,922 ha or equal to 267.70% cropping intensity and the maximum profit of Rp
893,253,809,281.00. When allocation of discharge reduced by 50% then the
optimum acreage acquired 612.88 hectares or equal to 213.77% cropping intensity
and the maximum profit of Rp 834,228,764,040.00. Overall water balance still
provide a surplus of 1.475.962.50 m3 per year for the allocation of debit mainstay
for Q = 100% and 12.8174 million m3 for the allocation mainstay discharge Q =
50%, so that the water allocation policy for the DI. Komering can be
implemented. The results of sensitivity analysis showed that changes in allocation
parameters are more sensitive to discharge mainstay optimum planting area of rice
compared with the kinds of commodity price changes in parameters of the
production unit. |
