Preference system for guided the selection of improvement type and assessment of soil based on expert opinion with weighted system

Abstract

The soil in different regions has many fundamental problems, including a high groundwater table, deformation of highly compressive clays, peat, etc. Most areas of these zones are waterlogged, swampy, and characterised by weak soils, making it difficult to construct them without addressing the stability of such structures. In many cases, soil conditions and soil materials are not ideal for the proposed or planned development. In such cases, the geotechnical engineer will consider how to resolve possible issues with feasible solutions carefully. This paper presents work resulting in the development of software that is used as a tool to guide and select the type of improvement and soil assessment. It allows users to learn about soil improvement and ground modification in engineering practice while providing the user with a tool that helps to solve soil improvement problems. An expert opinion was designed and conducted to obtain the weighted matrix for evaluation selection of improvement type based on specific criteria. A Software Development Life Cycle (SDLC) was followed, and in terms of design, implementation, testing and evaluation were conducted. The evaluation result based on the System Usability Scale was performed and evaluated, and it shows the proposed tool was accepted and suitable to use by the end-user.
