Ahmad Bima Nusa, A. Perwira Mulia Tarigan, Sirojuzilam Sirojuzilam, Agus Purwoko


This study aims to analyse the factors that influence the potential for tidal flooding in the northern part of Medan City. This research was conducted in the northern part of Medan City in 3 sub-districts, namely Medan Belawan District, Medan Marelan District and Medan Labuhan District, which are potentially prone to tidal flooding. Determination of the sample in this study is to use the technique of purposive sampling. In this study, interviews were conducted with 211 respondents, all of whom were sub-village heads in each affected village. Data analysis was performed using logistic regression analysis. Based on the results of the tests carried out, the variables that have a significant effect on the dependent variable (potential tidal flooding) are elevation, slope, distance from the sea, distance from rivers, land-use, and drainage density. Medium that does not have a significant effect is the aspect, rainfall and soil type.
