Pertumbuhan dan Produksi Tanaman Pegagan (Centella asiatica (L.) Urban) terhadap Pemberian Kompos Tongkol Jagung dan Pupuk Organik Cair Kombinasi Bonggol Pisang serta Daun Kelor

Abstract

Gotu kola is a medicinal plant that is widely used as a medicine for dermatological and non-dermatological diseases. The demand for gotu kola extract continues to increase but its availability is decreasing due to limited exploitation and cultivation of gotu kola. In the current cultivation of gotu kola, inorganic fertilizers are still used to increase production. Therefore, research is needed to determine the effect of giving Corn Cob Compost and Liquid Organic Fertilizer Combination of Banana Stem and Moringa Leaves based on the dosage of use in increasing the biomass of gotu kola. This research was conducted on Jl. Harmonika Baru, Padang Bulan Selayang II, Kec. Medan Selayang, Medan City, North Sumatra, with an altitude of ± 25 meters above sea level. This research was conducted from August 2024 to November 2024. This study used a Randomized Complete Block Design (RCBD) with two treatment factors, namely the provision of corn cob compost: 0; 6.25; 12.5; and 18.75 tons/ha and POC combination of banana stump and moringa leaves: 0; 75; 150; and 225 mL/L. Data were analyzed using analysis of variance, significant analysis of variance was continued using Duncan's Multiple Range Test with a level of 5%. The results showed that the provision of corn cob compost had a significant effect on increasing the biomass of pegagan plants compared to plants that were not given corn cob compost. The best treatment of corn cob compost fertilization was obtained at 12,5 tons/ha. Liquid organic fertilizer combination of banana stump and moringa leaves and the interaction between the two did not have a significant effect on all parameters.
