Abstract

The present study was investigated the effect of fiber mass fraction on the tensile and fatigue strength of oil palm fiber reinforced composite and resin as the matrix. Fatigue test has been performed by using rotary bending fatigue machine. The specimens were made by press hand lay-up with matrix to fiber mass ratio was 90:10, 80:20 and 70:30 respectively. Fracture surface of fatigue specimens have also been observed by using digital camera to knowing the failure mode. The results showed that the tensile and fatigue strength and fatigue life increased with increasing the fiber mass fraction as seen in the S-N curve. The fatigue limit was found 0.27 MPa, 0.55 MPa, and 0.82 MPa for composites with 90:10, 80:20 and 70:30 of matrix to fiber mass ratio respectively. The observed failure modes were matrix cracking, fiber debonding, and fiber breaking.

Abstract

The purpose of this community service activity is to assist the recovery of social activities and address the crisis of electricity and clean water following the flash floods in Pesisir Selatan Regency, particularly in Kampung Langgai and Barung-Barung Balantai Health Center, which were the most severely affected areas. The methods employed included conducting a needs assessment survey of the affected communities, procuring and installing a 5.5 kW generator set at Nurul Wahidah Mosque as a social center, distributing ten solar-powered lamps to residents’ homes, and rehabilitating the clean water system at the health center by replacing the water pump and installing new piping networks from the ring well and Pamsimas sources. Additionally, training was provided on the operation and maintenance of electrical equipment, along with socialization on the importance of clean water to prevent post-flood diseases. The results demonstrated a significant improvement in access to electricity and clean water in the affected areas. The mosque resumed its function as a center for social activities, homes and roads received adequate lighting, and health services at the health center became fully operational again. The conclusion of this activity is that appropriate technology-based interventions, such as the provision of generator sets, solar lamps, and water filtration system repairs, are effective in supporting post-disaster recovery and enhancing community resilience. The sustainability of the program can be strengthened through regular training and cross-sector collaboration to build resilient infrastructure in disaster-prone areas.

Abstract

This community engagement program aims to improve irrigation efficiency and reduce farmers' dependence on rain-fed water through the implementation of solar-powered pumping technology in Nagari Tanjung Barulak, Tanah Datar Regency, West Sumatra, Indonesia. The program adopted a Participatory Action Research (PAR) approach, actively engaging farmers in the planning, installation, training, and evaluation of the irrigation system. The intervention included the installation of a 25 kWp solar-powered pumping system equipped with photovoltaic (PV) panels and a DC submersible pump, followed by operational and maintenance training for approximately 30 farmers. The results demonstrated that the system was capable of irrigating approximately 100 hectares of agricultural land on a rotational basis, increasing irrigation water availability by up to 60% compared with previous conditions. In addition, irrigation operating costs were reduced by approximately 40% due to decreased reliance on fossil fuels. Farmers' knowledge and technical skills also improved substantially, with 85% of participants able to operate the system independently after completing the training. The program produced a fully functional solar-powered pumping system, practical training modules, and a community-based irrigation management group to ensure long-term sustainability. Overall, the findings indicate that implementing solar-powered irrigation through a participatory approach is an effective strategy for enhancing irrigation efficiency, lowering production costs, and strengthening farmers' capacity to manage water resources independently. The program offers a scalable and sustainable model that can be replicated in other regions with similar environmental and socio-economic characteristics.
