Intensive use of chemical fertilizers in the cultivation of rampai tomatoes ( Solanum lycopersicum L. var. cerasiforme ) has the potential to reduce environmental quality and soil fertility, so that environmentally friendly and sustainable fertilizer alternatives are needed. This study aims to examine the effect of liquid organic fertilizer (POC) made from Azolla microphylla and shallot skin on the growth and yield of rampai tomatoes. The study used an experimental method with a completely randomized design (CRD) consisting of six treatments, namely the control without fertilizer (P0), the positive control of POC Ratu Biogen 2 ml/L (P1), and a combination of POC Azolla microphylla and shallot skin with a concentration of 25 ml/L (P2), 35 ml/L (P3), 45 ml/L (P4), and 55 ml/L (P5), each with three replications. The parameters observed included plant height, number of leaves, flowering time, number of fruits, and fruit weight. Data were analyzed using ANOVA at a significance level of 5% and continued with Duncan's test. The results showed that the application of POC significantly affected all growth parameters and yield of tomato plants (p < 0.05). Treatment P5 (55 ml/L) gave the best results with a plant height of 46.8 cm, the number of leaves 26 strands, the fastest flowering time of 21 days after planting, the number of fruits 25 pieces, and fruit weight 25 grams. The high phosphorus and potassium content as well as bioactive compounds in POC are thought to play an important role in increasing the vegetative and generative growth of plants. Thus, POC made from Azolla microphylla and shallot skin has the potential as an effective environmentally friendly alternative fertilizer to increase the productivity of tomato plants.
