Environmental Aspect in Infrastructure Planning Using Starlet-Perdana Model

Abstract

Starlet-Perdana stands for Stabilisasi & Rancangbangun Lereng Terpadu - Perkuatan Dayadukung Tanah (Stabilization & Design Integration of Slope - Strengthening of Soil Bearing Capacity). The research is carried out in the northern parts of Bandung Basin at Cilengkrang and Jatinangor areas, around the foot of Gunung Manglayang and Jatinangor. The soil and rock materials are from weathered volcanic rocks. Areas that have been identified as landslide-prone are required some geotechnical engineering as well as direction in environmental management and monitoring. This paper presents a model of slope stability and soil bearing capacity to support infrastructure planning. This paper explains the relationship of slope with Factor of Safety (FS), application of Starlet model, soil bearing capacity, and improvement of expansive soil. The research activity began with a literature study, field survey as well as data collection, field analysis and laboratory analysis of soil / rock mechanics, delineation of landslide-prone areas, analysis of the relationship between slope and Factor of Safety (FS), calculation of soil bearing capacity, map data processing. Infrastructure planning needs to have a strong and long-term element, so the direction of the environmental management and monitoring is required as one of the efforts in environmental feasibility studies.
