Abstract

Davao City, Philippines, is located in a high seismic zone along the Pacific Ring of Fire, where residential buildings are highly vulnerable to earthquake damage. This community service program aimed to improve earthquake risk awareness and understanding of simple earthquake-resistant housing concepts among students and teachers of Sekolah Indonesia Davao (SID). The program was conducted through preparatory coordination, educational implementation, and evaluation stages. Educational activities included pre-tests, distribution of booklets, lectures on basic structural principles of earthquake-resistant houses, video demonstrations, discussions, and post-tests. The results showed a significant improvement in participants’ understanding, with correct responses increasing from 36% in the pre-test to 82% in the post-test. Participant feedback also indicated high satisfaction with the relevance, clarity, and usefulness of the materials. The program demonstrates that school-based education can serve as an effective community-based earthquake mitigation strategy in high seismic regions.

Abstract

Increased development of urban areas often leads to a reduction in rainwater catchment area, increasing surface runoff and potential inundation. One of the construction technologies that can be used to overcome this problem is pervious concrete, which is a type of concrete with an open cavity structure that allows rainwater to seep directly into the soil. This study aims to analyze the composition of the porous concrete mixture that is optimal for pavement applications in green open space (RTH) areas in Trenggalek Regency. The research method used an experimental approach with variations in coarse aggregate sizes of 5–10 mm, 10–20 mm, and 20–30 mm as well as different combinations of aggregate proportions. The parameters analyzed include the compressive strength of the concrete, porosity, and permeability. The results showed that the combination of aggregate sizes of 10–20 mm and 5–10 mm with a composition of 50%:50% produced the most optimal porous concrete performance with a compressive strength of 22.40 MPa at the age of 28 days, a porosity value of 16.25%, and a permeability of 1.16 cm/s. This value meets concrete quality requirements for light pavement applications such as parking areas and pedestrian paths according to national standards. The results of this study show that the variation in aggregate size has a significant effect on the balance between the mechanical properties and the hydraulic properties of porous concrete. With these characteristics, porous concrete has the potential to be used as a pavement material in green open space areas to increase the ability of rainwater infiltration and support sustainable infrastructure development in Trenggalek Regency.
