    Abstract
    The decline in agricultural land area in Indonesia causes agricultural cultivation to be constrained in the provision of land to increasing food needs, thus encouraging the agricultural sector to overcome these obstacles by increasing the application of agriculture of narrow land such as hydroponic fertigation system of pakcoy. This study was aimedto examine the fertigationwith hydroponic cropping method of pakcoy. Research at screen home scale consisted of 2 treatments and 26 replications, ie irrigation for 6 hours and watering for 8 hours. The parameters were the concentration of AB mixed nutrient solution, water discharge, wet weight and dry weight of plant, and economic analysis. The result showed that the concentration of AB mixed solution was 3.12% N, 0,0000003% P, and 3.76% K, the average initial water discharge for 6 hours was 1.40 x 10-3 l s, for watering for 8 hours was 1.05 x 10-3 l/s, and the final average water discharge for watering for 6 hours was 6.24 x 10-3 l/s, for irrigation for 8 hours was 4.67 x 10-3 l/s, the wet weights of pakcoy plants was ranged from 70.33 to 72.03g and the dry weight of pakcoy plants was ranged from 1.27 to 1.32 g, and the economic analysis of fixed costs Rp 279.023,5/year, the cost not fixed Rp 28.6/hour, basic cost in the first year of Rp 296.2/kg, and cost of goods in the fifth year Rp 94.1/kg.
     
    Penurunan luasan lahan pertanian di Indonesia menyebabkan kegiatan budidaya pertanian mengalami kendala dalam penyediaan lahan untuk pemenuhan kebutuhan pangan yang semakin meningkat, sehingga mendorong sektor pertanian untuk mengatasi kendala tersebut dengan meningkatkan penerapan pertanian lahan sempit seperti sistem fertigasi hidroponik pada tanaman pakcoy.Penelitian ini bertujuan untuk mengkaji fertigasi dengan metode hidroponik pada tanaman pakcoy. Penelitian dalam skala rumah kasa terdiri dari 2 perlakuan dan 26 ulangan, yaitu pengairan selama 6 jam dan pengairan selama 8 jam. Parameter yang diamati meliputi konsentrasi larutan nutrisi AB mix, debit air, bobot basah dan bobot kering tanaman, dan analisis ekonomi. Hasil penelitian menunjukkan konsentrasi larutan AB mix yakni 3,12 % N, 0,0000003 % P, dan 3,76 % K, debit air awal rata-rata untuk pengairan selama 6 jam yakni 1,40 x 10-3 l/s, untuk pengairan selama 8 jam yakni 1,05 x 10-3 l/s, dan debit air akhir rata-rata untuk pengairan selama 6 jam yakni 6,24 x 10-3 l/s, untuk pengairan selama 8 jam yakni 4,67 x 10-3 l/s, bobot basah tanaman bayam berkisar 70,33 – 72,03 g dan bobot kering tanaman pakcoy berkisar 1,27 – 1,32 g, dan analisis ekonomi yakni biaya tetap Rp 279.023,5/tahun, biaya tidak tetap Rp 28,6/jam, biaya pokok pada tahun pertama Rp 296,2/kg, dan biaya pokok pada tahun kelima Rp 94,1/kg.
