Abstract

Keseragaman tetesan adalah parameter yang krusial dalammengukur kinierja jaringan irigasi tetes. Semakin tinggi koefisien keseragaman tetesan menunjukkan kinerja jaringan yang semakin baik. Dan kinerja terbaik dari jaringan irigasi tetes dapat diperoleh dengan mengoptimasi parameter-parameter yang mempengaruhi, seperti panjang dan kemiringan pipa lateral, diameter dan jarak antar emitter, serta panjang durasi penetesan.

Penelitian ini dijalankan dengan metode eksperimental di Laboratorium dengan cara mengamati dan mengukur langsung hasil tetesan di masing-masing emitter menggunakan pipa lateral dari PVC. Kemudian perhitungan koefisien keseragaman dihubungkan terhadap parameter aliran pipa dripline untuk mendapatkan parameter yang menghasilkan keseragaman terbaik.

Penelitian menghasilkan bahwa keseragaman tetesan optimum diperoleh pada kemiringan pipa lateral terbaiknya yaitu 0.2% dan panjang pipa lateral kurang dari 12 meter. Sementara semakin besar diameter lubang penetes menghasilkan keseragaman tetesan yang semakin menurun, dan semakin besar jarak antar penetes menghasilkan keseragaman tetesan yang semakin baik.
