Abstract

Palaan Irrigated Paddy Field Area is in Malang Regency. Paddy field production strongly supports food security. The problem of the efficiency of irrigation canals in paddy fields causes water availability to decrease. Preliminary observations showed that the total efficiency of irrigation canals was 61.48% (64% in plot I and 92.17% in plot 2). In addition, farmers also have difficulty determining cropping patterns due to erratic weather. This study aimed to determine the water balance in Palaan irrigated paddy fields and identify the optimization of cropping patterns. The method used to determine the water balance is by evaluating the availability of irrigation water and irrigation water requirements. Irrigation water requirements are calculated using Cropwat 8.0 software. The availability of irrigation water is obtained based on canal discharge data and measurements of irrigation canal discharge in the field. The SOLVER linear program in Microsoft Excel is also used in the Identification process for optimizing cropping patterns. The results showed that there was a water surplus in plots 1 and deficit in plots 2. The condition occurred due to a less-than-optimal cropping pattern. Optimization of cropping patterns is very important to obtain cropping patterns that are in accordance with the maximum utilization of water availability. The function of optimization constraints is the availability of land area and the availability of irrigation canal discharge. The cropping patterns resulting from the optimization of plots 1 and 2 were Paddy- Paddy- Paddy Palawija and Paddy Palawija- Palawija- Palawija, respectively. The optimal land area in plot I is the paddy planting period I and II, with an area of 11.42 ha. Paddy Palawija planting period III was 6.28 ha and 5.14 ha respectively. Paddy Palawija planting area in plot 2 periods I was 3.69 ha and 29.76 ha respectively. Palawija planting period II and planting period III were 19.68 ha and 7.11 ha respectively. This research will be helpful for farmers, irrigation managers, and stakeholders in the agricultural sector to improve regional food security.
