**1. Introduction**

Raising food crop production remains the top priority for the government. This is done to meet the increasing food needs and the expanding number of people in Indonesia. One of the hindrances faced in increasing production is climate change. The world of agriculture is faced with more significant challenges, mainly due to global climate change, which impacts the area of sub-optimal land with more severe stress levels [1].

Climate change will have negative impacts on water resources, agriculture, forestry, health, and the vulnerability of public infrastructure, as well as the extinction of various species [2]. The area under rice cultivation that is nationally threatened with drought in the next one or two decades will increase from 0.3–1.4% to 3.1–7.8%, while the area that is unharvested due to drought will also increase from 0.04–0.41% to 0.04–1.87% [3]. On the other hand, the La Nina impact caused an increase in floodprone cropping areas from 0.75–2.68% to 0.97–2.99%, and the area that is unharvested from 0.24–0.73% to 8.7–13.38%. As a result, the risk of decreasing food production, due to floods and droughts, will rise from 2.4–5.0% to more than 10% [4].

Survey activities for the improvement of tertiary irrigation networks intensively in irrigated rice fields in the Kendal Regency were carried out in 30 (thirty) villages spread over 11 (eleven) subdistricts. The survey location is in the form of agroecosystems of rice fields irrigated with technical irrigation networks and semi-technical irrigation networks.
