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.

Abstract

The problem of plastic waste in the ocean is a global problem that endangers the quality of sea water and the marine ecosystem as a whole. This article discusses the relationship between how to manage plastic waste and how it affects seawater quality, such as pH, temperature, salinity, dissolved oxygen (DO), and biological oxygen demand (BOD5). Research from the literature shows that plastic waste, especially microplastics and macroplastics, can affect the chemical and physical quality of sea water. For example, a decrease in pH levels due to accumulated organic acids, local heating due to sunlight absorbed by plastic, and changes in salinity due to interaction with fresh water. In addition, the accumulation of plastic causes a reduction in dissolved oxygen (DO) and an increase in BOD5 levels, which is detrimental to marine ecosystems. Decreased water quality can endanger marine species because these species are very dependent on the chemical balance of the water. Despite much research on the impact of plastic waste on water quality, there remains a gap in understanding the long-term impacts and the need for more comprehensive plastic waste management. Further research is needed to resolve these issues and create more effective management strategies.

Abstract

One solution to urban farming is hydroponic cultivation. Currently, the development of the world of agriculture, especially in the field of hydroponics, is increasingly rapid. When compared to conventional farming, hydroponics has advantages that conventional farming does not have. One plant that is often cultivated hydroponically is the cherry tomato plant. The growth and production of tomatoes with a good hydroponic system requires the right concentration and volume of nutrients. This research used a non-factorial randomized block design (CRD) with Nutrient concentration (N) treatment, consisting of 5 levels, namely: N1 = 800 ppm, N2 = 900 ppm, N3 = 1000 ppm, N4 = 1100 ppm and N5 = 1200 ppm. The results showed that nutrient concentration had an effect on the generative growth phase, but had no significant effect on the vegetative growth phase of cherry tomato plants. Nutrient concentration influences the morphology and physiology of cherry tomato plants. Nutrient concentration had a significant effect on the production of cherry tomato plants hydroponically with the heaviest fruit weight per plant found in the AB Mix nutrient concentration of 1000 ppm (N3) of 97.89 g.
