Abstract

Background: The agricultural areas of Ponjong, Gunungkidul, are dominated by marginal drylands with low soil fertility and organic matter content. Farmers often rely on chemical fertilizers and open burning of crop residues, leading to soil degradation and environmental pollution. Biochar technology offers an eco-friendly solution to improve soil health and reduce waste.Aims: This study aims to strengthen the capacity of the Giri Muda Farmers Group in producing and applying biochar derived from agricultural waste and promoting sustainable soil management practices through participatory technology transfer.Methods: The program was implemented through participatory stages including preparation, socialization, training, demonstration, and field application. The rotary pyrolysis unit was introduced for efficient biochar production using rice straw and maize stalks as feedstock. Evaluation was conducted using pre- and post-tests, observation, and interviews.Results: Farmers demonstrated a 38% improvement in knowledge scores, and 100% of participants were able to operate the pyrolysis equipment independently. Field trials showed improved soil aggregation, higher moisture retention, and more vigorous maize seedling growth on biochar-amended plots. The farmers also committed to continuing biochar production collectively.Conclusion: The community service program successfully transferred appropriate pyrolysis technology to local farmers, improving soil quality, resource efficiency, and community empowerment. The initiative demonstrates that biochar production from agricultural waste can simultaneously address environmental issues and strengthen rural livelihoods.

Abstract

Water scarcity limits soil productivity, but applying biochar can effectively enhance soil water retention in vulnerable areas. This study evaluated the effects of biochar types and application rates on the maximum moisture content of sandy soils in Gunungkidul, Indonesia. A completely randomized design was used to test rice husk and blotong biochar, alongside raw rice husk and a control, at varying application rates. Maximum soil moisture capacity was experimentally measured to determine treatment efficacy. Results indicated that biochar application significantly influenced soil moisture retention. Among the treatments, a lower application rate of rice husk biochar provided the most substantial improvement in water holding capacity compared to the control. Conversely, higher rates of biochar or the use of raw materials were less effective and, in some cases, reduced water retention. Conclusively, optimizing both the biochar feedstock and its application rate is critical; specific low-dose biochar applications can optimally enhance soil moisture retention, offering a practical strategy for sustainable agricultural management in semi-arid regions.
