Abstract

Activities before and after coal mining have both positive and negative impacts. So this requires a change in post-mining function, where post-mining land can become a useful or productive area. This study uses qualitative research methods. Data collection techniques are by observing the existing conditions of post-coal mining land. Other data collection comes from data on ecosystem services for food providers in Tanah Laut Regency. The analytical method used is descriptive qualitative. It can be concluded that post-coal mining land in Tanah Laut Regency has the potential to become agricultural and plantation areas. The review is based on data on ecosystem services that provide food, namely the form of land is classified as medium, which means that the land can be used for food needs, taking into account land-use methods.

Abstract

Road layout is a fundamental framework that shapes the long-term development of a city. A road network with high connectivity provides residents with more efficient travel options and better access to public facilities, while low connectivity tends to increase dependence on private vehicles and extend travel distances. This study aims to measure the connectivity of physical road infrastructure in the Aerocity Area of Banjarbaru City, which is designated as a transportation activity center based on Regional Regulation No. 4 of 2024. The method used is quantitative analysis using three indicators: Road Density Index, Beta Connectivity Index, and Gamma Connectivity Index. Road network data in 2025, including road length, number of segments, and number of intersections, was analyzed using ArcMap software. The analysis results show that the connectivity of the Aerocity Area based on travel route choices is classified as good, with an overall Beta Index value of 1.47 (>1). However, the connectivity cannot be said to be perfect, as indicated by the Gamma Index value of 0.49 (<1). The low Gamma Index value is caused by many road segments that form cul-de-sacs (dead ends) so that they have not been optimally developed. It is lead to the recommendation that although the Aerocity Area has a good choice of routes from the Road Density Index, its structural connectivity still needs to be improved by optimizing intersections and avoiding the development of single-access areas.

Abstract

Road network configuration is a permanent element of urban morphology that influences spatial utilization patterns, mobility, and public accessibility. Good network connectivity encourages the use of active and public transportation, while low connectivity increases reliance on private vehicles. This study aims to evaluate the performance of road network connectivity in Banjarmasin City, focusing on Banjarmasin Tengah District as the City Service Center (PPK), and comparing it with other districts. The study uses a quantitative approach with spatial data analysis for the 2021–2025 period using ArcMap software. Three indicators are used: the Road Density Index, the Beta Connectivity Index, and the Gamma Connectivity Index, with road segments as the unit of analysis according to the Indonesian Road Capacity Guidelines. The results show that Banjarmasin Tengah District has the highest road density, reflecting the availability of relatively good physical infrastructure. The highest beta connectivity values ​​are also found in Banjarmasin Tengah and Banjarmasin Timur, although generally still in the low–moderate category. Meanwhile, gamma connectivity values ​​across all districts are relatively low, with an average of around 13% of optimal conditions. These findings indicate the need to improve connectivity between segments, particularly in local and neighborhood road networks, to support a more efficient and sustainable urban transportation system.
