Abstract

This study aims to evaluate the effect of goat manure and Mutiara NPK inorganic fertilizer on the vegetative growth, biomass, and yield of long bean (Vigna sinensis L.). The research was conducted using a factorial Randomized Group Design (RAK) consisting of two main factors. The first factor was the dose of goat manure with three levels: J1 (2 kg/plot), J2 (3 kg/plot), and J3 (4 kg/plot). The second factor was the application of NPK Mutiara fertilizer with four levels: P0 (control/no treatment), P1 (100 kg/ha or 24 g/plot), P2 (150 kg/ha or 36 g/plot), and P3 (200 kg/ha or 49 g/plot). Each experimental unit consisted of a uniform number of long bean plants to ensure reliable observations. The results indicated that both goat manure and NPK fertilizer significantly influenced vegetative growth parameters, including plant height, leaf number, and stem diameter, as well as yield components such as pod number, pod length, and total biomass. Furthermore, there was a significant interaction between goat manure and NPK application, where the optimal combination resulted in the highest biomass accumulation and pod yield. Specifically, the combination of the highest goat manure dose (J3) and moderate NPK dose (P2) provided the most favorable effect on long bean growth and productivity. These findings suggest that integrating organic and inorganic fertilizers can optimize nutrient availability, support sustainable crop production, and improve long bean yields. The study provides practical guidance for farmers seeking environmentally friendly fertilization strategies to enhance legume crop performance, while promoting soil fertility and sustainable agricultural practices.

Abstract

This community service program was carried out with the main objective of reducing farmers’ dependence on chemical pesticides by introducing and training them in the production of botanical pesticides made from soursop leaves (Annona muricata) and lemongrass (Cymbopogon citratus). The program was implemented in Dusun II Bakaru, Siwalubanua I Village, Gunungsitoli Idanoi District, in collaboration with the Tanjung Morawa Farmers Group as the primary partner. The activities were systematically designed through several stages, including socialization about the negative impacts of chemical pesticides, training in the preparation of botanical pesticides, field assistance during application, and evaluation of the results. During implementation, farmers showed great enthusiasm in participating in every training session. Based on the evaluation results, farmers’ understanding of the benefits and working mechanisms of botanical pesticides increased by 85%. Moreover, the application of these natural pesticides successfully reduced pest attack intensity by up to 70%, which had a positive impact on crop yields. This activity not only provided ecological benefits by reducing chemical residues in the environment but also fostered entrepreneurial awareness among farmers. Several participants even began developing small-scale businesses to produce botanical pesticides independently. Thus, this community service program has made a tangible contribution to realizing sustainable agriculture, enhancing farmers’ self-reliance, and promoting the utilization of local resources as a new economic potential for rural communities.
