Abstract. Harahap F, Siregar ARS, Idramsa, Suriani C, Edi S, Panggabean NH, Daulae AH, Pohan SD, Tanjung AA, Pertiwi SI, Kairani A. 2026. In vitro plant regeneration of Cattleya sp. from Protocorm-Like Bodies (PLBs) using coconut water and activated charcoal. Asian J Agric 10 (1): g100130. https://doi.org/10.13057/asianjagric/g100130. Cattleya sp. is an ornamental orchid whose seeds lack of endosperm, making natural germination and propagation difficult. In vitro culture using Protocorm-Like Bodies (PLBs) offers an alternative for mass propagation. This study aimed to evaluate the effects of coconut water and activated charcoal on the in vitro regeneration of Cattleya sp. PLBs. A completely randomized design was employed with varying concentrations of coconut water (0, 5, and 10%) and activated charcoal (0, 0.1, 0.2, and 0.3 g/L). Morphological parameters observed included time to shoot emergence, number of leaves, shoots, and roots, as well as shoot color. Data were analyzed using two-way ANOVA. The results showed that coconut water significantly accelerated shoot emergence with 10% of coconut water producing the fastest response (12 days after treatment). Activated charcoal enhanced shoot and leaf formation with 0.3 g/L, producing the highest number of shoot and leaf. Root formation was optimal at lower charcoal concentrations. Overall, the combination of coconut water and activated charcoal significantly influenced PLBS growth and regeneration. These findings indicate that appropriate combinations of organic additives can optimize in vitro regeneration of Cattleya sp. and support efficient orchid propagation.

Abstract

This study aims to determine the effect of Liquid Organic Fertilizer (POC) from durian peel (Durio zibethinus Murr.) on the growth of mustard greens (Brassica juncea L.). This study was conducted at the Greenhouse, Medan State University using a non-factorial Completely Randomized Design (CRD) consisting of four treatments with six replications, resulting in 24 experimental units. The parameters observed included plant height, number of leaves, root length, fresh weight, and dry weight of the plant. Based on the results of the study, it was found that the levels of nutrients contained in the liquid organic fertilizer from durian peel waste were 0.93% C-Organic, 0.36% Total Nitrogen, 0.21% P2O5, 0.05% K2O, and 0.02% Total Ca. The application of liquid organic fertilizer from durian peel waste had a significant effect (p <0.05) on all growth and production parameters of mustard greens (Brassica juncea L.). Based on the results of the Duncan's Multiple Range Test (DMRT), the most optimal treatment for mustard greens growth was a concentration of 300 ml of Organic Fertilizer (POC) and 1,000 ml of water. This indicates that the nutrient absorption effectiveness of durian peel POC is sufficient to support maximum vegetative plant growth.
