Abstract

The rapid growth of commercial and residential activities in city centers often exerts pressure on the existence of green spaces. This study analyzes the condition, adequacy, and spatial distribution of Green Open Space (GOS) in the central area of Tasikmalaya City, specifically in Cihideung and Tawang Districts, utilizing Geographic Information Systems (GIS). The research employs a descriptive qualitative approach supported by field surveys and spatial data analysis to map locations and calculate GOS areas. The results indicate a significant deficit in GOS availability in both districts, with an estimated area of only 15-20%, falling well below the minimum standard of 30% mandated by Law Number 26 of 2007. In terms of distribution, GOS is uneven and fragmented; green spaces are concentrated primarily in public facilities and city parks such as Dadaha Park and the City Square, while high-density residential areas and commercial zones lack sufficient vegetation. The study concludes that spatial planning interventions are required through the optimization of residual spaces, revitalization of existing GOS, and implementation of green architecture (such as vertical gardens) to address ecological imbalances caused by urbanization pressures in the city center.

Abstract

This study aims to evaluate the housing distribution patterns in Tawang District, Tasikmalaya City, which is a central urban area experiencing rapid residential infrastructure development. Limited land availability, increasing population, and urbanization pressures have led to increasingly complex pattern changes, necessitating mapping of housing distribution patterns to understand city growth trends. The technique applied is a quantitative approach using Average Nearest Neighbor (ANN) analysis on housing location data derived from satellite image interpretation. The analysis results reveal that the housing distribution exhibits a dispersed pattern, as evidenced by a nearest neighbor ratio of 1.41 and a Z-score of 2.82, indicating statistical significance. This dispersed pattern is influenced by factors such as accessibility, changes in land use, and spatial planning policies designating Tawang District as a strategic area with mixed-use functions. In addition, there are indications that space usage is not always appropriate, considering that some housing appears outside the official residential zones. These findings emphasize the importance of better monitoring of space usage so that housing development can align with existing spatial plans. Overall, this study provides insights into the spatial dynamics of housing growth, which play a crucial role in urban planning.
