Tingkat Keterjangkauan Halte Transjakarta di Wilayah DKI Jakarta Menggunakan Teknik Buffer

Abstract

The growth in the number of private vehicles in DKI Jakarta causes congestion and pollution, prompting the need to strengthen public transportation systems such as Transjakarta. This research aims to analyze the level of affordability of Transjakarta BRT stops using buffer techniques in Geographic Information Systems (GIS). The method used is a descriptive quantitative approach with a 400 meter radius buffer technique from each bus stop, which is considered the maximum walking distance. Spatial data was obtained from the Geospatial Information Agency (BIG) and JakartaSatu, then analyzed by overlaying with city administrative boundaries. Results show that Central Jakarta has the highest affordability (73.4%), while North Jakarta (13%), West Jakarta (18.8%), East Jakarta (19.8%) and South Jakarta (22.6%) are classified as low to very low. This inequality reflects the unequal distribution of access to public transportation. In conclusion, although the Transjakarta network covers the entire administrative area, its service coverage is still concentrated in the core city. Therefore, it is recommended to expand the BRT network, add bus stops in areas with low affordability, and integrate transportation modes and feeder systems for equal accessibility.
