Abstract

Sistem irigasi merupakan faktor kunci dalam mendukung produktivitas pertanian, khususnya di wilayah dengan kontur berbukit seperti Desa Belancan, Kintamani. Pemenuhan kebutuhan air di daerah ini banyak mengandalkan pompa air untuk mengalirkan air dari sumber ke lahan pertanian. Penelitian ini bertujuan untuk menganalisis kebutuhan energi pompa yang digunakan untuk memenuhi kebutuhan air tanaman di lahan pertanian Desa Abian, Kintamani. Metode penelitian menggunakan metode analisis kuantitatif melalui observasi dan beberapa wawancara terhadap 3 responden, untuk mengumpulkan data teknis pompa (daya, kapasitas, efisiensi), data topografi (elevasi sumber air dan lahan), serta data kebutuhan air berdasarkan jenis tanaman yang dibudidayakan. Perhitungan dilakukan dengan menggunakan rumus kebutuhan air irigasi (ETc dan Kc tanaman) serta analisis energi pompa berdasarkan head total, debit, dan efisiensi system. Hasil analisis menunjukkan bahwa kebutuhan air rata-rata untuk tanaman hortikultura di Desa Abian mencapai 738 mm/hari, sedangkan debit total air untuk memenuhi suplai air di lahan pertanian tersebut berkisar antara 1.040,4 – 1.035 mm/hari, tergantung kapasitas pompa dan kondisi head. Efisiensi pompa yang diamati berada pada kisaran 73,6 – 89,8%, menunjukkan adanya potensi optimasi melalui perbaikan sistem perpipaan, pemilihan pompa yang tepat, dan pengaturan waktu operasi.

 

Irrigation systems are a key factor in supporting agricultural productivity, especially in hilly areas such as Belancan Village, Kintamani. Meeting water needs in this area relies heavily on water pumps to deliver water from the source to agricultural land. This study aims to analyze the energy requirements of pumps used to meet the water needs of crops on agricultural land in Abian Village, Kintamani. The research method employs quantitative analysis through observations and interviews with three respondents to collect technical data on the pumps (power, capacity, efficiency), topographic data (elevation of water sources and fields), and water requirement data based on the types of crops cultivated. Calculations were performed using irrigation water requirement formulas (ETc and Kc of crops) and pump energy analysis based on total head, flow rate, and system efficiency. The analysis results show that the average water requirement for horticultural crops in Abian Village reaches 738 mm/day, while the total water flow rate to meet the water supply in the agricultural land ranges from 1,040.4 to 1,035 mm/day, depending on the pump capacity and head conditions. The observed pump efficiency ranged from 73.6–89.8%, indicating potential for optimization through improvements to the piping system, selection of appropriate pumps, and adjustment of operating schedules.
