Abstract

Water availability in Desa Mekar Saluyu has become increasingly unstable due to seasonal variability and land‑use change that reduces infiltration and baseflow. This community service program implemented a hydraulic ram pump (hydram) on the Cikatomel River as an off‑grid water‑lifting technology for irrigation and non-consumtive domestic reserves. The Program combined technical installation with community capacity strengthening through site survey and discharge measurement, hydraulic–mechanical design and fabrication, installation with simple civil works, community training, and field evaluation. The potential beneficiaries include approximately 200 farmers, with a village agricultural area of around 400 ha, but the initial service trial focused on a 120 m distribution line. The driving discharge at the diversion weir was about 4 L/s. The delivery discharge achieved ±1.0–1.2 L/s with pump pressure around 2.1 bar and waste‑valve frequency 45–50 cycles/min, enabling an effective lift of about 25 m and potential daily volume of 86.4 to 103.7 m3 under continuous operation. The novelty of this program lies in the integration of hydram pump installation, a steel safety cage to protect the unit from river-related risk, and community-based operation and maintenance SOP coordinated with village officials. This activity improved initial access to water and highlighted the importance of local ownership, routine inspection, and watershed conservation for long-term system sustainability.

Abstract

The temporary closure of the final disposal site (landfill) for 1–2 days during holidays causes waste accumulation, which has become a concern among residents. BUMDes Moroberkah's waste management still relies on manual open burning, resulting in air pollution and scattered combustion residues. This community service program aimed to provide a solution by implementing appropriate technology in the form of an incinerator machine. The program was conducted in two stages: on-site machine testing, followed by unit handover and training for BUMDes management. Test results showed that the incinerator operated optimally, with a waste-reduction capacity of about 25 kg/hour. The internal air circulation system and chimney design effectively reduced exhaust emissions, while the machine contained combustion residues, helping maintain environmental cleanliness. The program also improved the BUMDes management’s understanding of standard operating procedures (SOPs) for machine operation and maintenance. This program provides an independent, comprehensive, and environmentally friendly waste management solution.
