Abstract

This study aims to explore the ability of Cellular Automata-Markov (CA-Markov) model in predicting the expansion of urban growth rate in Ambon, Indonesia, and Gaza Strip, Palestine. Using a literature study approach, this research collected and analyzed secondary data on land use change, population growth, and factors affecting urbanization in both regions. The results of the analysis show that the CA-Markov model has high accuracy in predicting land use change, and is able to describe the spatial dynamics of built-up land growth. This research emphasizes the importance of integrating environmental aspects in land use planning to achieve sustainable development. The findings are expected to provide useful recommendations for policy makers in managing urban growth, as well as enrich the literature on the application of the CA-Markov model in different contexts.

Abstract

Tiakur City, the capital of Southwest Maluku Regency, has undergone significant physical development between 2015 and 2025, driven by population growth and economic activities. This study employs a quantitative approach using remote sensing technology with PlanetScope satellite imagery to analyze land cover changes. The analysis reveals an increase in built-up land area from 171.29 hectares (7.31%) in 2015 to 395.66 hectares (16.89%) in 2025, while non-built-up land experienced a decline. These findings indicate a rapid development rate and highlight the importance of sustainable spatial planning. In conclusion, understanding the patterns and intensity of land cover changes in Tiakur City is crucial for evaluating spatial planning policies and improving infrastructure development planning for the future.

Abstract

Teluk Baguala District, Ambon City is frequently affected by flood and landslide disasters. This study uses the Maximum Entropy method to model flood and landslide hazard areas based on environmental variables and the spatial distribution of disaster occurrences. The flood mapping results show that areas with low vulnerability cover the largest area, totaling 5,296.07 hectares, while medium-risk areas cover only 188.84 hectares, and high-risk areas cover 493.97 hectares. The area with low landslide vulnerability reaches 2,595.19 hectares, whereas medium vulnerability areas are smaller at 2,327.26 hectares, and very vulnerable or high-risk areas cover only 694.73 hectares. The flood validation test shows an AUC value of 0.974, while the landslide AUC value is 0.851. These mapping results are expected to assist the government in flood and landslide disaster mitigation efforts in the future.
