Analisis Risiko bagi Aset Sistem Pembetungan Menggunakan Analisis Spatial

Abstract

Sewerage systems are important to ensure that wastes discharged at the domestic and industrial levels are well maintained so as not to impact the environment. Sewerage system assets should be monitored and maintained to minimize risks from occurring. Factors that lead to the risk of occurrence of these assets should be identified, as well as location for these risks. This study aims to identify some risks and potential risk locations for the assets in the sewerage system. To achieve this goal, the risk factors that will occur need to be identified. The Skudai north area was chosen as the study area. The analysis is assessing the risk, based on risks factor that was identified, which is the degree of gradient in which the asset resides, as well as the age factor of an aged asset. Higher gradient areas have risks to assets, and in terms of asset age risk, older assets are at higher risk. The analysis results show that most assets are low risk (90.8%), a little of asset at middle risks (8.9%), while high risk assets are not much (0.3%). The results of this analysis can be improved with more factors included to the model. The results of this analysis are expected to assist stakeholders in identifying risky asset positions, thereby assisting in making the best planning and decisions for these risky assets.
