Penelitian ini bertujuan untuk: 1) mengetahui pengaruh pemberian pupuk organik cair limbah cair tahu dan Nasa dengan konsentrasi yang berbeda terhadap pertumbuhan dan hasil tanaman pakcoy, 2) mengetahui pengaruh pemberian pupuk organik cair limbah cair tahu dan Nasa dengan interval pemberian yang berbeda terhadap pertumbuhan dan hasil tanaman pakcoy, 3) mengetahui pengaruh kombinasi antara konsentrasi dan interval pemberian pupuk organik cair tahu dan Nasa yang terbaik untuk pertumbuhan dan hasil tanaman pakcoy. Penelitian ini dilaksanakan pada bulan September 2018 hingga Oktober 2018 di kebun percobaan Fakultas Pertanian Universitas Jenderal Soedirman, Kelurahan Karangwangkal, Kecamatan Purwokerto Utara, Kabupaten Banyumas dan Laboratorium Agronomi dan Hortikultura Fakultas Pertanian, Universitas Jenderal Soedirman. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok Lengkap sebagai rancangan dasarnya. Ada dua faktor yang diteliti, yaitu: 1) konsentrasi pencampuran pupuk organik cair limbah cair tahu dan Nasa (C) yang terdiri dari: kontrol (C0), pupuk organik cair limbah cair tahu 100% (C1), pupuk organik cair limbah cair tahu 75%+pupuk organik cair Nasa 25% (C2), pupuk organik cair limbah cair tahu 50%+pupuk organik cair Nasa 50% (C3), pupuk organik cair limbah cair tahu 25%+pupuk organik cair Nasa 75% (C4), pupuk organik cair Nasa 100% (C5) dan 2) interval pemberian pupuk organik cair (I) yang terdiri dari: pemberian 1 minggu sekali (I1), pemberian 2 minggu sekali (I2), pemberian 3 minggu sekali (I3). Hasil penelitian menunjukkan bahwa: 1) pemberian pupuk organik cair limbah cair tahu dan Nasa berbagai kosentrasi memberikan pengaruh yang nyata terhadap tinggi tanaman, jumlah daun, bobot tanaman segar, bobot tajuk segar dan bobot tanaman kering serta memberikan pengaruh yang sangat nyata terhadap bobot tajuk kering tanaman pakcoy, perlakuan konsentrasi menghasilkan tanaman pakcoy tertinggi sebanyak 99,32 t/ha, 2) interval pemberian pupuk organik cair limbah cair tahu dan Nasa 1 minggu sekali, 2 minggu sekali dan 3 minggu sekali memberikan pertumbuhan dan hasil tanaman pakcoy yang sama, 3) interaksi perlakuan konsentrasi pada berbagai interval pemberian pupuk organik cair memberikan respon yang sama pada pertumbuhan dan hasil tanaman pakcoy.

This research aims to: 1) understand the effect of applying tofu liquid waste organic fertilizer and Nasa with various concentrations on the growth and yield of pak choi plants, 2) understand the effect of giving tofu liquid waste organic fertilizer and Nasa with various intervals on the growth and yield of pak choi plants, 3) understand the best effect of the concentration combinations and interval dosing times of tofu liquid waste organic fertilizer and Nasa for the growth and yield of pak choi plants. This research was conducted from September 2018 to October 2018 in the experimental garden of the Faculty of Agriculture of Jenderal Soedirman University, Karangwangkal Urban Village, North Purwokerto Sub-District, Banyumas Regency and the Agronomy and Horticulture Laboratory of the Faculty of Agriculture, Jenderal Soedirman University. The applied research design is the Randomized Complete Block Design (RCBD) as the basic design. There are two factors of study, and those are: 1) the mixing concentration of tofu liquid waste organic fertilizer and Nasa (C) which consists of: control (C0),100% tofu liquid waste organic fertilizer (C1), 75% of tofu liquid waste organic fertilizer + 25% of Nasa liquid organic fertilizer (C2), 50% of tofu liquid waste organic fertilizer + 50% of Nasa liquid organic fertilizer C3), 25% of tofu liquid waste organic fertilizer + 75% of Nasa liquid organic fertilizer  (C4), 100% of Nasa liquid organic fertilizer (C5) and 2) the interval of dosing liquid organic fertilizer (I) consisting of: once a week (I1), once every 2 weeks (I2), and once every 3 weeks (I3). The results of the research showed that: 1) the application of tofu liquid waste and Nasa liquid organic fertilizer at various concentrations gave a significant effect on plant height, number of leaves, fresh plant weight, fresh crown weight and dry plant weight and gave a very significant effect on the dry crown weight of pakcoy plants, the concentration treatment resulted in plants the highest pakcoy as much as 99,32 t/ha, 2) the dosing interval of tofu liquid waste organic fertilizer and Nasa once per week, once every 2 weeks and once every 3 weeks resulted in the same growth and yield of pak choi plants, 3) the interaction of concentration treatments at various intervals of dosing liquid organic fertilizer resulted in the same response to the growth and yield of pak choi plants.
