Description One of the obstacles in providing irrigation water is the difficulty in determining the right parameters to be used in the controlling of timing and amount of irrigation water according to crop needs. One of the alternative parameters that could be considered in order to meet the water needs of plants is the irrigation control based on evaporation. This study aims to produce an evaporative irrigation system design and determine the crop coefficients of pepper. The drip irrigation network consists of a supply tank and distribution pipes that provide water to the plant pots. The network valve opening and closing arrangements are made based on the evaporation in the supply tank. This research was conducted in a plant house for 5 months by observing the observations made on the water balance components, including the rate of evaporation which is measured based on changes in the water level in the water supply tank. The results showed that the evapotranspiration outside the houseplant was greater than that in the plant house. At the beginning of planting pepper, the evapotranspiration was 5.2 mm/day in the plant house and 4.9 mm/day outside. The average evapotranspiration during observation inside the plant house was 4.1 mm/day and 3.8 mm/day outside. Meanwhile, evaporation outside the plant house is smaller than that inside the plant house which ranges from 2-5 mm/day. Provision of water with this evaporative irrigation system of 5.2 mm/day has been able to meet the needs of 4.1 mm/day of evapotranspiration water for pepper plants. The provision of water has been able to encourage the growth of primary branches and flowering. Normal pepper plant growth during this study with calculated crop coefficients ranging from 0.1–0.7.
Salah satu kendala dalam pemberian air irigasi adalah sulitnya menetapkan parameter yang digunakan untuk pengaturan waktu dan jumlah air irigasi yang sesuai dengan kebutuhan tanaman. Salah satu alternatif parameter yang dapat digunakan adalah berdasarkan evaporasi. Penelitian ini bertujuan menghasilkan rancangan sistem irigasi evaporatif dan mengetahui berbagai koefisien tanaman lada. Jaringan irigasi tetes terdiri dari tangki suplay dan pipa distribusi yang memberikan air ke pot tanaman. Pengaturan buka tutup klep jaringan dilakukan berdasarkan evaporasi di tangki suplay. Penelitian dilakukan di rumah tanaman selama 5 bulan dengan mengamati komponen neraca air di antaranya adalah laju evaporasi yang diukur berdasarkan perubahan level air dalam tangki penyuplai air. Hasil penelitian menunjukkan bahwa evapotranspirasi di luar rumah tanaman lebih besar dari pada yang di dalam rumah tanaman. Saat awal penanaman tanaman lada, evapotranspirasi yang terjadi sebesar 5,2 mm/hari di dalam rumah tanaman dan 4,9 mm/hari di luar rumah tanaman. Evapotranspirasi rata-rata selama pengamatan di dalam rumah tanaman sebesar 4,1 mm/hari dan di luar rumah tanaman 3,8 mm/hari. Pemberian air dengan sistem irigasi evaporatif ini sebesar 5,2 mm/hari telah mampu memenuhi kebutuhan air evapotranspirasi tanaman lada 4,1 mm/hari. Pemberian air tersebut telah mampu mendorong pertumbuhan cabang primer dan pembungaan. Pertumbuhan tanaman lada normal selama penelitian ini dengan koefisien tanaman terhitung berkisar antara 0,1–0,7.
