Abstract

Riam Kanan irrigation project is cosntucted for supporting and developing the agriculture irrigation system in South Kalimantan Province. Unfortunately, according to the current condition, main function on the irrigation itself has been changed to supply water for fisheries local industry along side the main channel. This paper is writen in order to recalculate the actual flow disharge since changing in utilization of irrigatiion main program. Discharge design 25 m3/ sec to supply originally paddy field around 8.641 ha at sub area A, actual only for 2.170 ha paddy field with 12,7 m3/ sec discharge flow. Another suplly is for fesh water consumption in Banjarmasin and Banjarbaru 1.300 litre/ sec all become 50.80%. Fisheries local insutry covered area 73 ha with water consumption 7,63 m3 sec  equal to 30,52% of design capacity. Hence the total discharge utilized is 20.33 m3/ sec or equal to 81.32% of total design capacity.

Abstract

The main problem of the agricultural activity is unbalanced system on the water supply to the rice plant field. This problem is faced on the case study of the B.Gt.6 Sub Area B Riam Kanan Irrigation System, which is unmatched between the water supply scheduling and its implementation on the field. To solve this problem is, determining the mathematical model which is easily to calculate. The aim of the mathematical model is to obtain the water supply schedule on the irrigation system from the channel to the rice plant field. The model of the linear program is obtained, which is hoped to be implemented on the irrigation network system actually with the qualitative aspect of the result by the case study in the B.Gt.6. Implementation of this study case obtaining the water supply schedule of the irrigation water are  xi3=36 and yi3=110  for the destination function-1 and also xi3=36 and yi3=113  for the destination function-2. The value of the minimum loss (z) is 6328 per square area unit in one day for the model I and 0 (zero) per square area unit in one day for the model II.Keywords: Water supply scheduling, linear program modelPermalink: http://www.ejournal.undip.ac.id/index.php/mkts/article/view/3895[How to cite: Fachrurazie, C., 2005, Model Penjadwalan Pembagian Air pada Sistem Irigasi (Studi Kasus: Irigasi Riam Kanan), Jurnal Media Komunikasi Teknik Sipil, Volume 13, Nomor 1, pp. 39-47] The main problem of the agricultural activity is unbalanced system on the water supply to the rice plant field.
