Penelitian menggunakan enam perlakuan dengan delapan ulangan. Hasil penelitian menunjukkan bahwa perlakuan nutrisi berpengaruh sangat nyata terhadap pertumbuhan dan produktivitas tanaman. Pada 28 hari setelah tanam (HST), perlakuan AB Mix (A0) menghasilkan tinggi tanaman sebesar 18,10 cm, jumlah daun 10,10 helai, dan lebar daun 4,19 cm. Sementara itu, perlakuan POC menghasilkan tinggi tanaman 8,90–9,82 cm, jumlah daun 4,25–5,13 helai, dan lebar daun 1,50–1,61 cm. Bobot segar dan bobot kering tertinggi juga diperoleh pada perlakuan AB Mix, masing-masing sebesar 4,82 g dan 0,335 g, sedangkan perlakuan POC menghasilkan bobot segar 0,416–0,476 g dan bobot kering 0,0375–0,0450 g. Pengamatan selama pemeliharaan menunjukkan adanya lendir pada area perakaran, klorosis, peningkatan pH hingga 7,94, serta nekrosis dan kelayuan menjelang panen pada perlakuan POC. Kondisi tersebut mengindikasikan bahwa penggunaan POC yang diuji belum mampu mendukung pertumbuhan pakcoy secara optimal dibandingkan AB Mix. Dengan demikian, formulasi dan konsentrasi POC masih perlu dioptimalkan agar berpotensi digunakan sebagai alternatif nutrisi pada sistem hidroponik sumbu. This study aimed to analyze the effects of liquid organic fertilizer (LOF) formulated from rice-washing water and tofu wastewater on the growth and productivity of pak choi ( Brassica rapa L.) cultivated using a wick hydroponic system, as well as to observe plant conditions during the cultivation period. The study consisted of six treatments with eight replicates. The results showed that nutrient treatments had a highly significant effect on plant growth and productivity. At 28 days after planting (DAP), the AB Mix treatment (A0) produced a plant height of 18.10 cm, 10.10 leaves, and a leaf width of 4.19 cm. In contrast, the LOF treatments produced plant heights of 8.90–9.82 cm, 4.25–5.13 leaves, and leaf widths of 1.50–1.61 cm. The highest fresh and dry weights were also obtained in the AB Mix treatment, reaching 4.82 g and 0.335 g, respectively, whereas the LOF treatments produced fresh weights of 0.416–0.476 g and dry weights of 0.0375–0.0450 g. Observations during cultivation revealed mucus formation around the roots, chlorosis, an increase in pH to 7.94, as well as necrosis and wilting toward harvest in the LOF treatments. These findings indicate that the tested LOF formulations were unable to support optimal pak choi growth compared with AB Mix under the concentrations used. Therefore, further optimization of the LOF formulation and concentration is needed before it can be considered an alternative nutrient source for wick hydroponic systems. }, issn = {2541-0083}, doi = {10.14710/baf.11.2.2026.%p}, url = {https://ejournal2.undip.ac.id/index.php/baf/article/view/34900} }
