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 study aims to analyze the level of production and price risk in red onion farming, as well as to examine the behavior of red onion farmers in Tiganderket Village, Tiganderket Subdistrict, Karo Regency. The main focus of the study is to understand the extent of the risks faced by farmers in red onion production and how their decisions and willingness to take risks influence farming practices. The sample was determined using a census method, where the entire population of red onion farmers in the study area was used as respondents, totaling 15 individuals. Primary data were collected through surveys and direct interviews, ensuring that the information reflects the actual conditions in the field. Data analysis was conducted using multiple linear regression to determine the influence of several variables on production and price risk levels. The results showed that the production risk in red onion farming in Tiganderket Village is considered high, indicated by a coefficient of variation of 0.52, which exceeds the threshold of 0.5. Conversely, the price risk is relatively low, with a coefficient of variation of 0.02, well below the threshold. Furthermore, the behavior of farmers in facing risks is also considered high; all respondents, 100%, demonstrated a willingness to take risks in red onion farming practices. These findings indicate that although red onion production carries a high level of risk, farmers still exhibit proactive behavior and a willingness to make risky decisions, while price fluctuation risks are relatively low. Therefore, economically, red onion farming can still be carried out with a reasonable degree of certainty. These results can serve as a basis for developing agricultural strategies and supportive policies for red onion farmers in Karo Regency.

Abstract

This community service program was carried out with the primary goal of enhancing the capacity and self-reliance of rice farmers in implementing the concept of Integrated Pest Management (IPM) based on environmentally friendly principles. Through this approach, farmers are expected to reduce their dependence on chemical pesticides, which have long posed potential negative impacts on health, the environment, and the ecological balance of paddy field ecosystems. The program was implemented through a seven-session workshop consisting of interactive lectures, group discussions, field demonstrations, and hands-on practice. Each session focused on improving farmers’ knowledge and practical skills, such as identifying natural pest enemies, utilizing botanical pesticides, and applying rice cultivation techniques that support IPM systems. Evaluation was conducted using a pre–post test on six indicators of knowledge and behavioral intention. The results showed a significant improvement: five out of six indicators reached a success rate above 80%, while farmers’ commitment to reducing chemical pesticide use reached 76%. These outcomes are consistent with recent literature (FAO, 2022; IRRI, 2020; Rahman et al., 2023), which highlights the effectiveness of IPM and the importance of participatory extension approaches in promoting sustainable agricultural practices. The program recommends continued mentoring, particularly in the production of botanical pesticides and the implementation of synchronized planting strategies, to strengthen the resilience of local agricultural ecosystems.
