Abstract

The environmentally friendly lightweight material is a concept for developing construction material technology. One way is to reduce density by using plastic waste such as Expanded Polystyrene (EPS) as the concrete aggregate. Although on the other hand, the mechanical value has decreased significantly. This research explains the development of lightweight concrete, EPS (BREA), which uses Modified EPS waste as coarse aggregate and pumice sand as fine material, obtained locally from Tidore Island. The mixture composition used in this study was 1 Cement: 2 Sand: 3 MEPS, where the compressive strength test was carried out to see its mechanical behaviour. The research shows that the composition above reduces the volume weight and compressive strength values by 56.12% and 78.46%, respectively, compared to normal concrete.

Abstract

Purpose: Landslides are hydrometeorological disasters frequently occurring in many places, particularly during the wet season. Slope stability analysis is the initial stage in defining countermeasures to prevent slope failure and mitigate the negative consequences. This study aims to apply the Limit Equilibrium Method (LEM) to examine the slope stability of the Dufadufa - Jambula road, with the SLIDE version 6.0 application serving as an analytical tool. Design/methodology/approach: Researchers use field measurement data to build a slide application slope model. The soil data used as input parameters are derived using the Robertson chart to interpret the sonder test findings. Findings: According to the results, the minimal slope factor of safety (fs) at the area under consideration is 0.247. It demonstrates that the road slope, which is the study location, is in critical condition; in other words, the slope of the Jambula-Dufadufa road segment has the potential to undergo a slide.
