Abstract

The karst landscape in Gunungkidul Regency faces major challenges in the agricultural sector, mainly due to limited water availability and dependence on rainfed farming systems. To overcome these challenges, a community service program was implemented by introducing rainwater harvesting and drip irrigation technology to the Giri Muda Farmer Group. This activity aims to increase water availability and water use efficiency in drylands through the application of environmentally friendly technology. The community service method includes an initial survey, system design planning, installation of rainwater harvesting and drip irrigation installations, and technical training for farmers on system operation and maintenance. The evaluation of the activities showed a significant increase in understanding and skills, which had a positive impact on horticultural agricultural productivity. The technology was well received by farmers and has great potential to be developed in the Gunungkidul region and other similar areas. This service program not only succeeded in increasing agricultural productivity in drylands but also contributed to mitigating the impacts of climate change.

Abstract

Organic fertilizers play a crucial role in improving soil quality and supporting sustainable agriculture in tropical regions. This study evaluates the quality of cow manure based on the solid organic fertilizer standards set by the Indonesian Ministry of Agriculture. Laboratory analyses were conducted on key chemical parameters, including organic C, C/N ratio, moisture content, macronutrients (N, P₂O₅, K₂O), and pH, accompanied by weekly composting temperature observations. The results show that the manure had a high organic C content (34.91%) and an ideal C/N ratio (17.24), indicating mature and stable compost. Moisture content (17.84%) and pH (8.17) were within the acceptable standard range, confirming good storage stability and suitability for acidic tropical soils. Nitrogen content (2.03%) met the minimum requirement, while P₂O₅ (1.26%) and K₂O (0.23%) were at moderate levels typical of cattle manure. Temperature measurements during composting showed a normal decomposition pattern, increasing from 32°C in week 1 to about 33°C in weeks 2–3 before declining in week 4, supporting the maturity of the final product. Overall, the analyzed cow manure meets the quality standards for solid organic fertilizer and has strong potential as a soil amendment and supplementary nutrient source in tropical agricultural systems.
