Abstract

Biofertilizer is a substance which contains microorganism and promotes plant growth by increasing the soil nutrient availability. The aim of this study was to analyze the growth and production of lowland and upland rice by using the biofertilizer in acid soils. Seven isolates of bacteria were used as biofertilizer, i.e. Bacillus sp., two strains of Pseudomonas sp., two strains of Azospirillum sp., and two strains of Azotobacter sp.. The treatments of this study were without fertilization, compost, 100% NPK, compost enriched with 7 isolates, compost enriched with 7 isolates + 50% NPK, compost enriched with 4 isolates, and compost enriched with 4 isolates + 50% NPK. The results showed that biofertilizer in compost improved nutrient content in acid soil, and increased rice growth and production as well. Compost enriched with 7 isolates 50% NPK showed the highest rice yield production both in the lowland and upland rice. The biofertilizer could reduced 50% utilization NPK fertilizer dosage in the first growing season.

Abstract

This community service activity aims to improve the efficiency of tilapia pond management through the implementation of a manually operated waterwheel system for the Wildatul Sholihah Activity Group in Bojong Village, Bogor Regency. The partner’s challenges include fluctuating water temperatures, low oxygen levels, and limited manpower, as pond maintenance is only carried out on weekends. As an initial solution, the service team conducted training and installed a simple manually operated waterwheel unit. The activity took place on May 28, 2025, and involved several stages: coordination, module preparation, equipment assembly, technical training, and field testing. The results showed that the waterwheel successfully improved water circulation and temperature stability, while also reducing the frequency of manual water replacement. Training participants demonstrated increased technical understanding, high enthusiasm, and the ability to operate and maintain the device independently. This initiative had a tangible impact in supporting more efficient and sustainable tilapia farming. In the future, the system has the potential to be further developed with the integration of digital technologies such as IoT-based monitoring systems
