Developing Strategic Operation of Water Management in Tidal Lowland Agriculture Areas of South Sumatera, Indonesia

By: Momon Sodik Imanudin, Armanto, M. E., Robiyanto Hendro Susanto.


The study objective was to develop a water management operational plan at tertiary blocks for rice and corn crops growth. Study area was reclaimed tidal lowland located at Primer 10, Delta Saleh, Banyuasin, South Sumatra, Indonesia This area was classified as C-typhology land (dry). The study method were: survey, field measurements, computer simulation, and field action research. Study stages were consisted of survey and monitoring, water status evaluation, water management scenarios design, model simulation, and model adaptation. Computer model of DRAINMOD had been used to estimate the water table status and to design water table control operation at tertiary blocks. Simulation results showed that the model worked properly which was indicated by comparing the simualted and observed water table with root mean square error of 1.45 cm, model efficiency of 0.97, and correlation coefficient of 0.84. Model adaptation for dry land condition (C-typhology) showed that the best scenario was land utilization pattern of rice-corn. This paper presented monthly water management operational plan for rice crop in first cropping season (MT1) during November-February period and for corn crop in second cropping season (MT2) during May-August period. Results of computer simulation and field study showed that the main objective of water management in this area was water retention in combination with leaching of the land.

Keywords: Water table control, tidal swamp area, DRAINMOD

    Sangat tertarik dan dijadikan referensi untuk pengelolaan air di lahan pasut
