Abstract:
Cabbage (Brassica oleracea var. KK Cross) is a widely consumed vegetable due to its high nutritional value, including vitamins A, B, and C, as well as essential minerals, carbohydrates, and proteins. The utilization of tofu wastewater as a source of organic nutrients presents a sustainable alternative to chemical fertilizers in agriculture. This study aimed to evaluate the effects of various concentrations of liquid organic fertilizer (LOF) derived from tofu wastewater on the growth and yield of cabbage plants. The experiment was conducted from July to October 2022 in Rarampadende Village, West Dolo District, Donggala Regency, Central Sulawesi, Indonesia, using a Randomized Group Design (RGD). Treatments included five LOF concentrations: P0 = control (no LOF), P1 = 5 ml/L, P2 = 10 ml/L, P3 = 15 ml/L, and P4 = 20 ml/L, each replicated three times for a total of 15 plots. Data were analyzed using ANOVA, and significant effects were further tested using the Honest Significant Difference (HSD) test at the 5% level. Results showed that tofu wastewater LOF significantly affected leaf width at 28 days after planting (DAP) and fresh weight at harvest. The best growth performance was observed in the P4 treatment (20 ml/L).

Keywords: Cabbage, Liquid Organic Fertilizer (LOF), and Tofu Wastewater.
