Abstract

This research examines the impact of land use change on mobility. Spatial problems arise due to increased activity, population, and transportation in the same space, necessitating the development of modeling strategies. This aligns with SDG 11 on cities and settlements, as well as the PRN's focus on transportation innovation. The urgency of this research lies in its adaptive and sustainable spatial prediction efforts aimed at controlling future land use. This study aims to analyze land use change patterns using the Cellular Automata Markov Chain (CA-Markov) model in Kupang City until 2043. CA-Markov simulations efficiently evaluate land cover changes and movement. The quantitative research method was conducted based on spatial predictions and spatial configuration. Quantum GIS (QGIS) and GeoSOS-FLUS were used to obtain results from each stage. There are three research stages. First, identification of land cover (land use in 2018 and 2023), driving factors (distance to settlements, airports, highways, elevation, slope, slope orientation, rainfall, population density), and conservation areas. Second, standardisation of spatial data. Third, land cover prediction using GeoSOS software (five-year prediction) to identify patterns of land use change. These findings emphasize the importance of using CA-Markov-based spatial predictions as a foundation for adaptive spatial planning to control land-use conversion and maintain sustainable spatial connectivity in Kupang City until 2043.

Abstract

This research aims to analyze the effectiveness of the Sea Toll system in supporting local commodity distribution and to assess the role of Tenau Kupang Port as a regional hub in East Nusa Tenggara Province (NTT). It employs a mixed-methods approach with quantitative-descriptive and explanatory designs, drawing on secondary data from KSOP Kupang and BPS NTT for 2023–2024. The analysis incorporates descriptive statistics, multiple linear regression, load factor analysis, total logistic cost (TLC), and quantitative SWOT. The results show that the Sea Toll system in NTT has achieved physical accessibility through regular inter-island connectivity but has not achieved functional accessibility due to low return loads, with the average load factor reaching only 24%. Regression analysis indicates that shipping frequency and return cargo volume have a significant effect on distribution effectiveness, while logistics costs and travel time exert a moderate positive influence. The Sea Toll Program reduces average logistics costs by 31% compared to conventional modes. The SWOT analysis yields an internal factor value of 2.09 and an external factor value of 2.56, placing Tenau Kupang Port in the growth strategy quadrant. This study concludes that the Sea Toll system is physically effective but not economically efficient. Strengthening the function of Tenau Kupang Port as a regional hub—through consolidation of local cargo, cold storage facilities, land-sea mode integration, and digitalization of logistics systems—represents a strategic step toward sustainable maritime logistics efficiency in Eastern Indonesia.
