D Densification is a phenomenon of increasing density of settlement characterized by an increasing number of buildings growing vertically and/or horizontally in a certain area. Kampung Jawa, which is located on the coastal border, is experiencing densification. As a result, the function of the coastal border area as local protection has decreased and even disappeared. The loss of the ecological function of the coastal border is characterized by tidal floods and floods in Kampung Jawa so that residents must evacuate if the village is flooded. The purpose of this research is to identify the factors that influence densification in Kampung Jawa, Wosi Village, West Manowkari District. It is expected that by knowing the factors referred to, it can be used to control densification that occurs in the coastal border area. The main data collection technique used is the questionnaire survey method to record data and examine variables that affect densification. The results of the theoretical investigation obtained three factors that are thought to have an effect on densification, namely strategic location, development of infrastructure (public facilities and infrastructure), and intensity of commercial land use. The analysis technique uses multiple linear regression with the help of Smart-PLS Software. The results showed that strategic location factors and infrastructure development (public facilities and infrastructure) proved to have an effect on densification in Kampung Jawa, while the commercial land use intensity factor did not. The strategic location of an area makes it more attractive than other regions, resulting in demand that drives an increase in builtup space. The availability of adequate infrastructure can increase the attractiveness of an area as a location for activities thereby increasing the demand for housing in the area. The main activity in Kampung Jawa is trade with a market being the center of economic activity. Based on the results of this study, densification in Kampung Jawa needs to be controlled by providing other activity centers in strategic places accompanied by the provision of the necessary infrastructure and facilities.
