Developing Mobile Application for Residential Property Business in Transit-Oriented Development Areas

Transit-oriented development (TOD) areas are being constructed in Indonesia, particularly in Jakarta, since the issuance of the Regulation of Minister of Agrarian Affairs and Spatial Planning in 2017. This development has led to an increasing supply of apartment units in Jakarta, but this is contrary to the declining residential property sales, which was at the worst level in 2019. Therefore, this study aims to determine the factors that influence consumer preferences in buying residential properties in the TOD area, which serves as the basis for planning residential apartments in the next TOD area development. This study adopts both quantitative and qualitative methods through desk study and benchmarking, as well as questionnaire surveys and fuzzy logic to achieve its objectives. The results obtained here showed that the order of priority factors for consumers intending to buy property is financial, property type, and demographic factors. Consumers intending to rent property prioritize property type, financial, and demographic factors. Moreover, the higher one's income means the lower one's interest in living in the TOD area. Another objective of this research is to harness many mobile internet users in Indonesia, reaching 53% of the total population, to develop a mobile phone-based application that serves as the platform for sale and purchase transactions of residential properties in the TOD area. The proposed application has six features: My Preferences, which provides recommendations for suitable apartment units according to user preferences; Search My Apartment; My Store; Mortgage Simulation; Payment Gateway; and Profile Settings.
