Principal Component Analysis Application for Determining Factors Influencing Drainage Construction Process in Residential Areas

Banda Aceh experiences flood-related problems yearly, specifically during peak rains, which inundates several residential areas and municipal protocol roads. One of the most effective ways of resolving this problem is by constructing drainage channels in settlements. However, there are various problems associated with using this process in the survey, planning, and construction stages. During the development process, numerous obstacles are experienced from various factors, thereby leading to less optimal planning and implementation process. Therefore, this research aims to determine the dominant factors influencing drainage construction in residential areas in Banda Aceh City, Indonesia. This is a quantitative research with data collected through a questionnaire from 200 respondents involved in constructing residential area drainage in Banda Aceh City from 2017 to 2020. The factors evaluated were pre-planning, planning, and implementation, which were analyzed using Principal Component Analysis (PCA). The results showed that the factors influencing the drainage construction of residential areas in Banda Aceh City consist of implementation barriers, implementation discrepancies, pre-planning, planning, land acquisition, and community involvement with a total variance of 70.449%, while the dominating factor has a variance of 31.030%.
