Peningkatan hasil tanaman sawi pagoda dapat dilakukan dengan menggunakan POC Bio Sugih dan nutrisi AB Mix dengan hidroponik rakit apung (Floating Hydroponic System). Tujuan penelitian ini adalah untuk mendapatkan konsentrasi POC Bio Sugih dan nutrisi AB Mix terbaik serta interaksi antara kedua faktor tersebut terhadap pertumbuhan dan hasil tanaman sawi pagoda secara hidroponik rakit apung. Penelitian ini dilaksanakan di Dinas Pangan Aceh, Naungan Pekarangan Edukasi Pangan dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala yang berlangsung dari bulan Januari sampai dengan Maret 2023. Penelitian ini menggunakan Rancangan Acak Kelompok pola faktorial 3x3 dengan 3 ulangan dan 2 faktor yang diteliti yaitu konsentrasi POC Bio Sugih 3 taraf (3, 6, 9 ml L-1 air) dan AB Mix 3 taraf (0, 7 dan 14 ml L-1 air). Konsentasi POC Bio Sugih berpengaruh tidak nyata terhadap tinggi tanaman dan jumlah daun pada umur 2, 3, 4 dan 5 Minggu Setelah Pindah Tanam (MSPT), panjang daun, lebar daun, panjang akar, dan bobot berangkasan basah tanaman. Pertumbuhan dan hasil tanaman sawi pagoda cenderung lebih baik dijumpai pada perlakuan konsentrasi POC Bio Sugih 3 ml L-1 air. Konsentrasi AB Mix berpengaruh sangat nyata terhadap tinggi tanaman dan jumlah daun pada umur 2, 3, 4 dan 5 MSPT, panjang daun, lebar daun, panjang akar dan bobot berangkasan basah tanaman. Pertumbuhan dan hasil tanaman sawi pagoda terbaik dijumpai pada perlakuan konsentrasi AB Mix 7 ml L-1 air. Interaksi antara POC Bio Sugih dan AB Mix berpengaruh nyata terhadap tinggi tanaman pada umur 2 MSPT, namun berpengaruh tidak nyata terhadap peubah lainnya. Pertumbuhan tanamna sawi pagoda terbaik terdapat pada kombinasi antara konsentrasi POC Bio Sugih 3 ml L-1 air dengan konsentrasi AB Mix 7 ml L-1 air.

Increasing the yield of pagoda mustard plants can be done by using LOF Bio Sugih and AB Mix nutrients with floating hydroponic rafts (Floating Hydroponic System). The purpose of this study was to obtain the best concentration of LOF Bio Sugih and AB Mix nutrients and the interaction between the two factors on the growth and yield of pagoda mustard plants in hydroponic floating rafts. This research was carried out at the Aceh Food Service, Shade of Food Education Yard and Plant Physiology Laboratory, Faculty of Agriculture, Syiah Kuala University which took place from January to March 2023. This study used a 3x3 factorial pattern Randomized Group Design with 3 replications and 2 factors studied, namely the concentration of LOF Bio Sugih 3 levels (3, 6, 9 ml L-1 water) and AB Mix 3 levels (0, 7 and 14 ml L-1 water). The concentration of POC Bio Sugih had no significant effect on plant height and number of leaves at the age of 2, 3, 4 and 5 weeks after transplanting (WAT), leaf length, leaf width, root length, and plant wet weight. The growth and yield of pagoda mustard plants tended to be better in the treatment of LOF Bio Sugih concentration of 3 ml L-1 water. The concentration of AB Mix had a very significant effect on plant height and number of leaves at the age of 2, 3, 4 and 5 WAT, leaf length, leaf width, root length and wet weight of plants. The best growth and yield of pagoda mustard plants were found in the AB Mix concentration treatment of 7 ml L-1 water. The interaction between LOF Bio Sugih and AB Mix had a significant effect on plant height at the age of 2 WAT, but had no significant effect on other variables. The best pagoda mustard plant growth was found in the combination of LOF Bio Sugih concentration of 3 ml L-1 water with AB Mix concentration of 7 ml L-1 water.
