“…coupled mutually, showing non-linear variations with large inertia and hysteresis [2,3]. The traditional control method tends to cause the system to have a large amount of overshoot, which is detrimental to water conservation [3,4]. The growth of the crop is hampered once the overshoot exceeds a certain value.…”

Smart irrigation for sustainable agricultural water supply has been a critical initiative. In this paper, a fuzzy control system is designed to realize intelligent and precise irrigation by combining fuzzy control with traditional feedback control based on the features that soil moisture has significant influence and ease of detection and adjustment in practical irrigation. The opening time of solenoid valve is decided by the control system in real time, and the deviation and deviation rate of change for soil moisture are regarded as input variables. The model of intelligent irrigation fuzzy control system is built and compared with the model of PID control by Simulink for simulation. The results show that the fuzzy control system operates stably and achieves real-time precise irrigation with faster response and stronger robustness. The issue of reduced accuracy in irrigation due to the coupling between human and environmental factors is effectively solved by this design.

“…Using the dynamic program method for optimization in the Tengoro Irrigation Area can increase profits by 20.84% in the first planting season and 0.85% in the second planting season [6]. In addition, it is known that there has been an increase in irrigation profits of 10.7% by implementing dynamic programs as an irrigation optimization method in the Amu Darya Watershed [7]. Then, it was also shown that optimization with a dynamic program could increase profits by 8% according to the availability of debits in the area [8].…”

Raknamo Irrigation area (1323 ha) has problems with water availability, especially during the dry season, which causes a decrease in the productivity of the agricultural products from local communities. This is due to the suboptimal water distribution system in the Raknamo Reservoir. This study aims to analyze and optimize water distribution in the Raknamo Reservoir to obtain the most optimal water distribution to fulfill agricultural land's water needs in various seasons. Optimization analysis is carried out using a deterministic dynamic program. With this program, a complex and large-scale problem can be dispart into several small parts (decomposition), which are then optimized. Based on the analysis results, the maximum profit that can be obtained from the cropping intensity is 16% in the normal season. Meanwhile, the highest increase of the land area is 218.64 ha. It is worth noting that this study uses a deterministic dynamic program for optimization analysis to dispose of the complex problem into smaller, manageable parts. This approach facilitates a more systematic and comprehensive analysis and provides a framework for future decision-making processes related to water management and agricultural planning. The study's methodology and findings can serve as a valuable reference for similar water-related challenges in other irrigation areas, thereby contributing to the broader agricultural research and sustainable water resource management field.

“…Penggunaan metode program dinamik untuk optimasi pada Daerah Irigasi Tengoro dapat meningkatkan keuntungan sebesar 20,84% pada Musim Tanam I dan 0,85% pada Musim Tanam II (Nalurita, Limantara and Prayogo, 2017). Selain itu, diketahui terjadi peningkatan keuntungan irigasi sebesar 10,7% dengan menerapkan program dinamik sebagai metode optimasi irigasi di daerah aliran sungai Amu Darya (Zhou et al, 2022). Kemudian, ditunjukkan pula bahwa optimasi dengan program dinamik dapat menghasilkan peningkatan keuntungan sebesar 8% sesuai ketersediaan debit yang ada pada daerah tersebut (Berbel and Exposito, 2022).…”

Daerah Irigasi Sarangan merupakan salah satu daerah irigasi yang memiliki permasalahan ketersediaan air, yaitu air yang ada tidak cukup untuk memenuhi kebutuhan air irigasi. Berdasarkan permasalahan tersebut, dibutuhkan upaya pengelolaan air secara optimal dengan teknik optimasi. Teknik optimasi yang digunakan adalah program dinamik deterministik. Tujuan penelitian adalah mengoptimalkan alokasi air irigasi sehingga diperoleh keuntungan yang maksimum. Fungsi tujuan optimasi adalah keuntungan maksimum dengan fungsi kendala berupa luas lahan dan ketersediaan debit. Pola tata tanam yang digunakan sesuai dengan Rencana Tata Tanam Global (RTTG) periode 2021-2022. Berdasarkan hasil optimasi, diperoleh peningkatan luas tanam serta keuntungan pada Musim Tanam I sebesar 3%, pada Musim Tanam II sebesar 6%, dan pada Musim Tanam III sebesar 7%. Penelitian ini dapat bermanfaat bagi dinas terkait untuk mengetahui pemberian air optimal yang dapat menghasilkan keuntungan maksimum berdasarkan ketersediaan air yang ada pada Daerah Irigasi Sarangan.
