Abstract

This community service program (PKM) aimed to strengthen the capacity of two partners—the Mbuah Page Farmers’ Group and the Youth Organization of Lau Solu Village—through outreach, training, hands-on implementation, and intensive mentoring on three appropriate technologies: floating rice rafts, backyard hydroponics, and the production of liquid organic fertilizer (LOF) based on local microorganisms. The methods included open outreach sessions, stepwise practical training, technology implementation on partners’ fields/yards, and weekly monitoring over three months using pre- and post-tests. Results show increased knowledge and skills among participants; a floating-raft prototype operated on flood-prone plots, an NFT (Nutrient Film Technique) backyard hydroponics system functioned as a demonstration unit, and household-scale LOF production became routine. Early impacts were observed in more efficient input use, greater availability of quick-harvest vegetables, and strengthened organizational governance within the Youth Organization. The program concluded with a sustainability plan comprising basic production kits for three cropping cycles, farm-business management training, and assistance in drafting proposals for support from the village government/BUMDes.

Abstract

Background: The fungus Beauveria bassiana (Balsamo) Vuill is an entomopathogenic fungus widely used as a biological control agent against insect pests in plantation, food, and horticultural crops. Beyond its role as a biocontrol agent, B. bassiana has also been reported to enhance seed germination and early growth of shallot plants. Objective: his study aimed to determine the germination response of shallot seeds (Allium ascalonicum L.) to seed soaking treatment using B. bassiana at varying concentrations and soaking durations. Methods: TA field experiment was conducted from January to March 2026 using a factorial Randomized Complete Block Design (RCBD) with two factors: concentration (V) and soaking duration (P). Parameters observed included germination percentage, germination rate, shoot height, leaf number, leaf length, root length. Results: The results showed that the concentration of 15 ml/L (V3) gave the best effect on all parameters, while the soaking duration of 9 hours (P1) was optimal and not significantly different from longer soaking durations. The combination treatment of V3P1 (15 ml/L + 9 hours) produced the highest germination percentage (35% at 25 days after planting), the best germination speed (11.3 days), as well as superior shoot height and root length. The ability of B. bassiana to enhance growth is thought to be due to the production of phytohormones such as auxin and gibberellin. Conclusions: In conclusion, soaking shallot seeds in a suspension of B. bassiana at a concentration of 15 ml/L for 9 hours is recommended to improve seed viability and growth

Abstract

Household waste is one of the major contributors to environmental problems in densely populated areas, including Kenangan Village in Percut Sei Tuan District. Limited waste management systems have led to the accumulation of organic waste, environmental pollution, and declining public health. At the same time, the rising cost of commercial animal feed has become an economic burden for low-income families. This community service program aims to provide an integrated solution through training on Black Soldier Fly (BSF) larvae cultivation to convert organic waste into animal feed and organic fertilizer. The implementation methods included lectures, discussions, demonstrations, hands-on practice, and field mentoring. The results indicate an improvement in the community’s understanding of organic waste processing, significant reduction of organic waste volume, and the production of maggot culture as livestock feed and organic fertilizer. In addition, participants were motivated to initiate small businesses based on maggot production and its residue. This program has proven to be effective as a circular economy solution that integrates waste management, household economic improvement, and community empowerment. The activity is recommended for broader and continuous implementation.

Abstract

The coconut palm (Cocos nucifera) is an economically and culturally significant crop widely cultivated in tropical regions, particularly in Indonesia. However, coconut productivity remains suboptimal due to aging plantations and poor soil conditions. To address this, biofertilizers such as Bacillus nigr have been proposed as sustainable alternatives to chemical fertilizers. This study aimed to evaluate the effect of Bacillus nigr-based liquid organic fertilizer (POC) on the early growth parameters of coconut plants aged 9 to 12 months. Conducted in Deli Serdang, North Sumatra, the experiment involved 38 coconut seedlings divided equally into treatment (POC) and control groups. Data on stem height were collected and analyzed using a T-test. The results demonstrated a statistically significant difference (p < 0.05) in stem height between the POC-treated and untreated plants, with notable growth advantages observed in the control group at 11 and 12 months. However, POC treatment showed promising effects at earlier growth stages (9–10 months). These findings suggest that Bacillus nigr-based POC may influence early vegetative growth, but long-term benefits and dosage optimization require further investigation. This study contributes to the growing body of knowledge on the role of microbial biofertilizers in sustainable coconut cultivation and offers insights for enhancing early-stage coconut growth using environmentally friendly agricultural practices.

Abstract

Shallot (Allium ascalonicum L.) is a horticultural commodity with high economic value, but its productivity is often constrained by declining soil fertility associated with prolonged and intensive inorganic fertilization. This study evaluated the growth and yield response of shallot to various eco-enzyme fertilizer dosages and identified the most effective dosage under polybag-based open-field experimental conditions. The experiment was arranged in a non-factorial Randomized Complete Block Design (RCBD) with five treatments and five replications: E0 (without eco-enzyme), E1 (100 mL plot⁻¹), E2 (200 mL plot⁻¹), E3 (300 mL plot⁻¹), and E4 (400 mL plot⁻¹). Each plot referred to one polybag experimental unit. The observed variables were plant height, number of leaves, number of tillers, fresh bulb weight, and dry bulb weight. The results showed that eco-enzyme dosage affected several vegetative variables at specific observation times, but the response was not uniform across all growth stages. E2 produced the highest plant height at 14, 28, and 42 days after planting (DAP), whereas E3 produced the highest leaf number at 28 DAP. Yield formation was more favorable under the lowest eco-enzyme dosage. Treatment E1 produced the highest fresh bulb weight (167.2 g plot⁻¹) and dry bulb weight (131.2 g plot⁻¹), corresponding to approximately 5.03% and 19.06% increases over the control, respectively. These findings indicate that 100 mL plot⁻¹ was the most efficient eco-enzyme dosage for improving bulb yield of Bima Brebes shallot under the conditions of this experiment.
