      Abstract
      Peningkatan produktivitas tanaman terung melalui pemupukan menggunakan alat penyemprotan (sprayer) yang mampu memecah larutan pupuk menjadi droplet yang halus serta memiliki kinerja yang optimum pada saat aplikasi di lahan. Penelitian ini bertujuan menganalisis efektivitas serta efisiensi kinerja sprayer gendong elektrik dan sprayer gendong semi-otomatis dengan modifikasi nosel two ways untuk pemupukan cair organik urin kelinci pada budidaya terung. Perlakuan liquid fertilizing diaplikasikan menggunakan sprayer gendong dengan nosel kerucut 1 lubang dan nosel kerucut 8 lubang dengan dosis POC urin kelinci yang sama sebesar 30 ml/tanaman. Parameter utama pengujian sprayer di laboratorium, yaitu tekanan cairan, debit penyemprotan efektif, lebar penyemprotan efektif, diameter droplet, dan kerapatan droplet. Hasil analisis menunjukan kombinasi sprayer gendong elektrik nosel kerucut 1 lubang (E-N1) unggul dibandingkan dengan kombinasi sprayer dan tipe nosel lainya. Hal ini ditandai dengan kombinasi E-N1 dapat menghasilkan tekanan penyemprotan sebesar 2,52 kgf/cm2 , diameter droplet sebesar 208,06 µm, kerapatan droplet sebesar 197 droplet/cm2 , lebar penyemprotan efektif sebesar 88 cm, dan debit penyemprotan 2,37 liter/menit. Alat tersebut mampu melakukan penyemprotan secara efisien dengan kapasitas lapang efektif 0,21 ha/jam, tingkat efisiensi lapang sebesar 94,87% dengan kapasitas keluaran sebesar 671,5 ha/jam, namun memiliki nilai losses penyemprotan sebesar 32,67%. Berdasarkan percobaan di lahan perlakuan E-N1 lebih efektif dengan waktu pemunculan bunga lebih cepat pada 41,6 HST, waktu pemunculan buah pada 44,8 HST, rata-rata bobot buah 92,6 gram/buah, dan produktivitas panen periode kedua sebesar 3,57 ton/ha
       
      Increasing eggplant productivity through fertilization using a sprayer capable of breaking down fertilizer solution into fine droplets and having optimal performance during field application. This study aims to analyze the effectiveness and efficiency of electric knapsack sprayers and semi-automatic knapsack sprayers with a modified two-ways nozzle for organic liquid fertilization using rabbit urine in eggplant cultivation. Liquid fertilizing treatments were applied using knapsack sprayers with a 1-hole cone nozzle and an 8-hole cone nozzle with the same dose of rabbit urine POC at 30 ml/plant. The main parameters for testing the sprayer in the laboratory were fluid pressure, effective spray rate, effective spray width, droplet diameter, and droplet density. The results of the analysis showed that the combination of an electric knapsack sprayer with a 1-hole cone nozzle (E-N1) was superior compared to other sprayer and nozzle type combinations. This was indicated by the E-N1 combination producing a spray pressure of 2.52 kgf/cm2 , a droplet diameter of 208.06 µm, a droplet density of 197 droplets/cm2 , with an effective spray width of 88 cm, and a spray rate of 2.37 liters/minute. The tool was able to spray efficiently with an effective field capacity of 0.21 ha/hour, a field efficiency of 94.87% with an output capacity of 671.5 ha/hour, but had a spray loss value of 32.67%. Based on field trials, the E-N1 treatment was more effective with faster flower emergence at 41.6 days after transplanting, fruit emergence at 44.8 days after transplanting, an average fruit weight of 92.6 grams/fruit, and a second period harvest productivity of 3.57 tons/ha.
