Abstract

Optimasi pola tanam merupakan langkah strategis untuk meningkatkan efisiensi penggunaan sumber daya air irigasi sekaligus mendukung produktivitas pertanian di daerah irigasi Salamdarma, Kabupaten Indramayu. Daerah irigasi ini memiliki luas seluas 35.627 ha yang mengairi 24.215 ha daerah Indramayu dan 11.412 ha mengairi daerah Subang. yang mencakup areal persawahan yang sebagian besar bergantung pada sistem irigasi teknis. Dengan debit air rata-rata sebesar 22,37 m³/detik, tantangan utama adalah bagaimana memastikan distribusi air yang merata, terutama pada musim kemarau, di tengah fluktuasi ketersediaan air akibat perubahan iklim. Pola tanam yang tidak optimal, seperti dominasi monokultur padi, sering kali mengakibatkan penggunaan air yang boros dan penurunan kesuburan tanah. Penelitian ini bertujuan untuk mengoptimalkan pola tanam berdasarkan analisis efisiensi air, rotasi tanaman, dan kesesuaian lahan di daerah irigasi Salamdarma. Metodologi yang digunakan mencakup analisis data sekunder, seperti data curah hujan, debit irigasi, dan tekstur tanah, serta simulasi pola tanam menggunakan model optimasi dengan alaat bantu Solver Add ins. Pola tanam yang dianalisis yang paling optimal ditanam kombinasi padi – padi – padi seluas 9,697 ha dan setengah dari lahan sisanya ditanam kombinasi palawija – palawija – palawija seluas 18,669 ha Hasil analisis menunjukkan bahwa pola tanam optimasi pola tanam pada Daerah Irigasi Salamdarma Kiri yang paling optimal dengan intensitas 231%. Hasil keuntungan optimasi pola tanam pada Daerah Irigasi Salamdarma Kiri keuntungan sebesar Rp 1,555,325,145,110.

Optimizing cropping patterns is a strategic step to increase the efficiency of irrigation water resource use while supporting agricultural productivity in the Salamdarma irrigation area, Indramayu Regency. This irrigation area covers an area of 35,627 ha, irrigating 24,215 ha of Indramayu and 11,412 ha of Subang, which includes rice fields that largely rely on technical irrigation systems. With an average water discharge of 22.37 m³/second, the main challenge is how to ensure equitable water distribution, especially during the dry season, amid fluctuations in water availability due to climate change. Suboptimal cropping patterns, such as the dominance of rice monoculture, often result in wasteful water use and decreased soil fertility. This study aims to optimize cropping patterns based on the analysis of water efficiency, crop rotation, and land suitability in the Salamdarma irrigation area. The methodology used includes secondary data analysis, such as rainfall data, irrigation discharge, and soil texture, as well as cropping pattern simulation using an optimization model with the Solver Add-ins tool. The most optimal analyzed cropping pattern is planted with a combination of rice - rice - rice covering an area of 9,697 ha and half of the remaining land is planted with a combination of secondary crops - secondary crops - secondary crops covering an area of 18,669 ha. The results of the analysis show that the most optimal cropping pattern optimization cropping pattern in the Salamdarma Kiri Irrigation Area with an intensity of 231%. The profit from optimizing the cropping pattern in the Salamdarma Kiri Irrigation Area is Rp 1,555,325,145,110.
