Abstract

Ternate City, located in the North Maluku archipelago, Indonesia has hilly geographical and morphological conditions that make it vulnerable to landslides. This research aims to identify potential landslide risks by utilizing Digital Elevation Model and slope morphology analysis, and provide recommendations for disaster mitigation. This study used Digital Elevation Model (DEM) data obtained from the Indonesian Geospatial Information Agency, as well as land use data extracted from Sentinel 2 satellite imagery. The Slope Morphology (SMORPH) method was applied to analyze the shape and slope, which was then used to generate a landslide potential map. The analysis results show that 1,391.72 hectares of area in Ternate City has a high risk of landslides, with factors such as slope slope, slope shape, and land use conditions contributing to soil stability. The study also identified the importance of risk mapping and socialization to the community on early signs of landslides to improve preparedness. This research confirms the need for comprehensive and sustainable mitigation efforts to reduce the impact of landslides in Ternate City. Recommendations include infrastructure strengthening, drainage channel construction, and reforestation in critical areas. The results of this study are expected to serve as a basis for policy makers in formulating more effective disaster mitigation strategies and increasing public awareness of the importance of wise environmental management.

Abstract

Tiakur City, the capital of Maluku Barat Daya 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

The impact of climate change on Asian forests is significant because it can affect temperature, rainfall, forest growth, seasonal patterns, and ecosystem balance. The research method used is a literature study that includes analyzing historical data, current observations, and monitoring climate change trends in the Asian region. The results show that climate change has led to an increase in average temperatures, changes in rainfall patterns, and melting of glaciers and ice in the Asian mountains. These impacts extend to various aspects of life, including ecosystems, agriculture, human well-being, and natural resource availability. Therefore, comprehensive mitigation and adaptation strategies and international cooperation are needed to protect Asia's forest ecosystems and increase people's resilience to the impacts of climate change.

Abstract

Economic growth, urbanization, and infrastructure development are the main drivers of the increase in built-up land area in Ternate Selatan Sub-district. This study aims to investigate and understand the dynamics of land use evolution over a period of one decade. Using satellite image data and image processing techniques, an analysis was conducted to identify significant changes in land cover, particularly in relation to economic growth, urbanization, and infrastructure development. The results showed an increase in the area of built-up land in Ternate SelatanSub-district from 2014 to 2024 along with changes in land use patterns that reflect development pressure. In 2014, the percentage of built-up land area in Ternate SelatanSub-district was 24.69% and continued to increase in 2024 to 31.44% of the total area of Ternate Island. In contrast to other land cover classes that experienced a decrease in area. The results of this study are expected to provide an important contribution for policy makers, environmentalists, and other stakeholders in designing appropriate measures to maintain the balance between economic growth and nature conservation in Ternate SelatanSub-district.

Abstract

Climate change has become a pressing global issue, with vulnerable countries such as the Russian Federation facing significant challenges. This research aims to explore the role of Russian government policies in addressing the impacts of global climate change. The research method used is a literature study that includes data analysis from various reliable sources. The results and discussion highlight that Russia is vulnerable to climate change due to its vast territory and dependence on the fossil fuel industry. Socio-economic impacts such as heat waves, forest fires and permafrost thawing have reinforced the urgency of mitigation and adaptation measures. Recommendations include strengthening climate policies, diversifying energy sources, raising public awareness, international collaboration, and technological innovation. By addressing challenges such as lack of public awareness and limited resources, Russia can play a more proactive role in protecting the environment and creating a sustainable future.

Abstract

This study presents a comprehensive analysis of the average Land Surface Temperature (LST) of Java Island, Indonesia, for the year 2024, utilizing the reduceRegions function in Google Earth Engine (GEE). Rapid urbanization and environmental changes on Java Island have significant implications for its climate and thermal conditions, necessitating effective monitoring and analysis of LST. The research employs satellite-based remote sensing techniques to assess the relationship between vegetation cover and surface temperatures, revealing that areas with higher vegetation density tend to exhibit lower surface temperatures. This finding aligns with previous studies, underscoring the importance of green spaces in urban environments. The analysis not only contributes to a deeper understanding of Java Island's environmental dynamics but also provides critical insights for policymakers and urban planners. The results can inform strategies for climate adaptation and sustainable development, addressing ongoing environmental challenges. Limitations of the study are acknowledged, and recommendations for future research are proposed, emphasizing the need for continued exploration of LST variations in relation to urbanization and climate change. Overall, this research serves as a valuable resource for enhancing environmental management practices on Java Island and similar regions facing rapid development.
