Abstract

Mucuna bracteata plants can be propagated in two ways: generatively and vegetatively. Vegetative propagation is done through cuttings, while generative propagation uses seeds. In 1999, Mucuna bracteata found it very difficult to produce flowers, fruits, and seeds. Due to this difficulty, propagation can be done through cuttings. This study uses a Non-Factorial Randomized Block Design (RBD) with 4 Treatments (P) and 6 Replications (U). The concentration of watering consists of 4 levels: P0 (0 ml), P1 (50 ml), P2 (150 ml), and P3 (250 ml). Meanwhile, the soaking duration also consists of 4 levels: P0 (0 minutes), P1 (5 minutes), P2 (10 minutes), and P3 (15 minutes). The results of the study showed that the interaction between the concentration of watering with MOL (Microorganism Local) from banana stems and the soaking duration did not have a significant effect on all parameters. Various concentrations of watering with MOL from banana stems and soaking duration significantly affected the growth of Mucuna bracteata. Although statistically, it did not show a significant effect, several treatment combinations could be observed, such as U6P3, which showed the highest root weight (15.44 grams). Then, the vine length was 117.1 cm, the number of leaves was 20, and the number of nodules was 11. As the highest values from P3, this shows the highest concentration of watering and soaking duration with MOL from banana stems. Thus, this effort can reduce agricultural waste and pathogens.

Abstract

Biomass Analysis of Mucuna bracteata DC Due to the Application of Coffee Husk Waste as an Organic Nutrient Source. Mucuna bracteata DC is a cover crop that plays a crucial role in soil conservation and soil fertility improvement. This study aims to analyze the effect of liquid organic fertilizer (LOF) derived from coffee husk waste on the biomass growth of Mucuna bracteata DC, particularly in terms of fresh shoot weight, fresh root weight, dry shoot weight, and dry root weight. The research was conducted at Jalan Kuali No. 50, Medan Petisah District. The experiment was designed using a Completely Randomized Block Design (CRBD) with a single-factor treatment consisting of seven LOF dosage levels: K0 (no treatment), K1 (5 mL/polybag), K2 (10 mL/polybag), K3 (15 mL/polybag), K4 (20 mL/polybag), K5 (25 mL/polybag), and K6 (30 mL/polybag), with four replications, totaling 28 experimental plots. The results showed that the application of coffee husk LOF significantly affected the biomass growth of Mucuna bracteata DC. The highest fresh shoot weight (9.51 g) and dry shoot weight (2.14 g) were recorded in treatment K6 (30 mL/polybag), whereas the highest fresh root weight (2.29 g) and dry root weight (0.32 g) were observed in treatment K5 (25 mL/polybag). Higher LOF doses generally increase plant biomass up to an optimal threshold, beyond which nutrient absorption efficiency by roots declines. Overall, the optimal LOF dosage for maximizing biomass growth in Mucuna bracteata DC ranges between 25–30 mL/polybag. The use of coffee husk waste as an organic nutrient source presents a sustainable alternative for improving plant productivity while reducing dependency on synthetic fertilizers.
