Abstract

Kupang City, as the capital of Nusa Tenggara Timur Province, faces significant challenges in land management and settlement development due to rapid population growth and urbanization. This study aims to analyze and evaluate land suitability for sustainable settlement development, considering relevant environmental factors. The method used is Spatial Multi-Criteria Analysis (SMCA), which integrates geospatial data from the Digital Elevation Model (DEM), including slope, road networks, rivers, economic activity centers, and coastlines. The analysis results indicate that out of the total area analyzed, 7,227.04 hectares have high suitability, 4,341.12 hectares have moderate suitability, and 3,967.85 hectares have low suitability. Areas with high suitability are generally located near roads, economic activity centers, have lower slope gradients, and are far from rivers and coastlines, making them ideal for infrastructure development. The discussion emphasizes the importance of spatial and participatory-based spatial planning, as well as the need for monitoring low-suitability areas to prevent disaster risks. In conclusion, this study provides policy recommendations for more sustainable settlement development in Kupang City, integrating land suitability analysis and involving the community in the planning process, thereby creating

Abstract

Peningkatan jumlah penduduk di Kota Ambon sejalan dengan peningkatan kegiatan manusia diberbagai sektor terutama sektor social dan ekonomi, sehingga kebutuhan akan sumberdaya lahan juga akan meningkat, sedangkan keberadaan lahan yang tetap dan pada akhirnya akan mengakibatkan alih fungsi lahan serta akan berdampak pada kerusakan lingkungan kedepannya. Sehubungan dengan hal tersebut, dalam pengembangan kawasan permukiman di Kota Ambon kedepannya, perlu dilakukan analisis spasial kesesuaian lahan untuk permukiman untuk penilaian kategori fungsi kawasan dan kesesuaian lahan permukiman berdasarkan kondisi fisik dan RTRW yang ada. Penelitin ini bertujuan untuk menganalisis secara spasial kesesuaian lahan untuk pengembangan kawasan permukiman di Kota Ambon dan untuk mengevaluasi kesesuaian pengembangan kawasan permukiman dengan RTRW Kota Ambon tahun 2011-203. Penelitian ini menggunakan metode Spatial Multi Criteria Analysis (SMCA). Hasil penelitian kemudian digunakan untuk mengevaluasi RTRW Kota Ambon 2011-2031. Hasil analisis SMCA menunjukan bahwa seluas 13.282, 46 ha yang sesuai dan 2.019, 88 ha yang cukup seusai pengembangan kawasan permukiman. Berdasarkan hasil evaluasi RTRW didapati banyak terdapat penyimpangan terkait pengembangan kawasan permukiman di kawasan lindung serta terkait jarak >100 m dari sempadan sungai yang tidak boleh dilakukan pembangun permukiman sesuai dengan Peraturan Pemerintah Republik Indonesia Nomor 38 Tahun 2011 yang belum ada di RTRW Kota Ambon, untuk ini hasil penelitian ini diharapkan dapat menjadi refrensi dalam evaluasi RTRW Kota Ambon kedepannya

Abstract

This research focuses on the spatial analysis of the relationship between vegetation index and land surface temperature in Ternate Island, Indonesia, which is becoming increasingly relevant amidst the phenomenon of rapid urbanization. The background of the research shows that land use change has the potential to reduce green open space, contributing to an increase in surface temperature that can trigger the Urban Heat Island (UHI) phenomenon. The methods used include utilizing Landsat 8 OLI/TRIS satellite image data to calculate NDVI and LST values and statistical analysis using Pearson's correlation test and Spearman's rho to identify the relationship between the two. The results showed a significant negative relationship between NDVI and LST, with a Pearson correlation coefficient of -0.613, indicating that areas with better vegetation cover tend to have lower surface temperatures, and non-vegetated areas influence the increase of land surface temperature. The discussion highlights the importance of vegetation in regulating surface temperature through evapotranspiration and shading processes and suggests the need for afforestation strategies to mitigate climate change on Ternate Island

Abstract

Gag Island in Raja Ampat Regency, Southwest Papua, has experienced significant land cover change due to intensive nickel mining activities since 2017, transforming tropical forest into open land with serious ecological and socio-economic impacts. This study analyzed the spatial dynamics of land cover change using 3-meter resolution PlanetScope satellite imagery (2017, 2021, 2025) through visual classification in ArcGIS Pro, with four land cover classes: settlement, open area, mining, and forest/garden. Results show an expansion of mining area from 4.53 hectares (2017) to 301.13 hectares (2025), accompanied by a decrease in mixed forest from 5,898.37 hectares to 5,576.21 hectares, and an increase in sedimentation that threatens coastal ecosystems and coral reefs. The discussion reveals contradictions between mining permit policies and small island protection regulations, as well as recommendations for high-resolution image-based monitoring and sustainable reclamation to mitigate impacts. This study provides a scientific basis for sustainable natural resource management on small islands with high conservation value.

Abstract

Ternate City in North Maluku, Indonesia, is experiencing rapid population growth and residential land development, with diverse topography and slopes that affect the expansion of built-up land. This study analyzed the development of built-up land in 1995 and 2025 based on slope levels using Landsat imagery and Digital Elevation Model (DEM) data. The results showed that built-up land expanded rapidly in the 8-25% slope zone (an increase of 96.8-372%) and the >25% zone (+206.5%), indicating that development pressure pushed urbanization into topographically difficult areas. Greenland conversion (903.78 ha less) also affected the environmental balance, while water bodies remained stable (67.58 ha). The dominance of steep slopes >40% (3,013.36 ha) is a major challenge for sustainable development. These findings emphasize the need for a spatial approach based on integrated geomorphological analysis, particularly landslide risk mitigation in steep slope zones, while meeting settlement needs

Ternate City in North Maluku, Indonesia, is experiencing rapid population growth and residential land development, with diverse topography and slopes that affect the expansion of built-up land. This study analyzed the development of built-up land in 1995 and 2025 based on slope levels using Landsat imagery and Digital Elevation Model (DEM) data. Results showed that built-up land expanded rapidly in the 8-25% slope zone (increased by 96.8-372%) and the >25% zone (+206.5%), indicating development pressure that drove urbanization to topographically challenging areas. Green land conversion (903.78 ha less) also affected the environmental balance, while water bodies remained stable (67.58 ha). The dominance of steep slopes >40% (3,013.36 ha) is a major challenge to sustainable development. The findings emphasize the need for a spatial approach based on integrated geomorphological analysis, particularly landslide risk mitigation in steep slope zones, while meeting settlement needs. The research makes an important contribution to the development of sustainable development strategies in island cities characterized by complex topography and limited flat land while offering a spatial-temporal evaluation model that can be applied in similar areas. Policy implications of the research include strengthening spatial regulations, applying special construction techniques in slope areas, and protecting protected areas to maintain the balance of the natural environment.

Abstract

Disaster management in the world has undergone a paradigm change that is from responsive to preventive, from sectoral to multi-sector, from government responsibility solely to joint responsibility, centralization to decentralization and from emergency response to disaster risk reduction. Based on 6 directives of the President of the Republic of Indonesia delivered during the Rakornas PB (Disaster Management) at surabaya, February 2, 2019 one of which is "Regional development planning must be based on aspects of DRR (Disaster Risk Reduction)". Disaster risk-based regional development planning aims to reduce the impact of disaster risk including, threats, vulnerabilities, and capacity. Vulnerability assessment in areas that have the potential to experience disaster events is one of the important factors that must be reviewed in disaster mitigation efforts. Vulnerability assessment with the concept of data from wisdom allows local policymakers to recognize their specific situation in the broader context of a similar situation, providing regional perspectives and important connections between regions. Based on the efforts that have been integrated between the program into city spatial planning, it is hoped that it can increase the resilience of the City in facing disasters and adapt to climate change.

Abstract

This study aims to analyze vegetation density in Ternate City, Indonesia, using the Modified Soil-Adjusted and Atmospherically Resistant Vegetation Index (MSARVI) algorithm and Sentinel-2A images processed through Google Earth Engine. The analysis results show that the vegetation density index values range from -0.54 to 1.16, with normalization resulting in four density classes: low, medium, dense, and very dense. Ternate Island sub-district had the largest area of very dense vegetation (4,133.12 hectares), while Ternate Tengah sub-district showed the lowest vegetation density, reflecting the significant impact of urbanization. This study revealed that despite anthropogenic pressures, Ternate Island remains an ecologically critical zone. These findings emphasize the importance of conservation efforts and afforestation initiatives to improve environmental resilience amidst the growing challenges of climate change and urban development.

Abstract

Landslides seriously threaten safety and sustainable development in Ternate City, Indonesia, due to tectonic activity, steep topography, high rainfall, and urbanization pressure. This study aims to map landslide-prone areas using Geographic Information System and the weighted overlay method by integrating seven parameters: elevation, slope, soil type, geology, land use, rainfall, and distance from active faults. The analysis results show that slopes >40% and areas near active faults have the highest risk. Based on the total area of 10,162 ha, 51% (5,197 ha) is classified as a high-risk zone, 31% (3,123 ha) as medium risk, and 18% (1,842 ha) as low risk. These findings emphasize the need for risk-zoning-based mitigation priorities, such as strengthening spatial planning policies, building disaster-resistant infrastructure, and educating communities. This research not only provides a scientific basis for development planning and disaster risk reduction in Ternate but also provides a methodological framework that can be adapted in other landslide-prone areas, especially in volcanic island regions with similar geographical conditions.

Abstract

The implementation of the 2013 curriculum was developed into a curriculum that combines various aspects, namely attitudes, knowledge, and skills. Through the 2013 curriculum, educators are required to be able to improve the quality of education so as to produce independent and creative students. Integrated science learning is presented in the context of science that includes the environment, technology, and society. Science education (science) can also be developed by relying on the uniqueness and excellence of a region, including culture and technology based on local wisdom (traditional). So that in schools there needs to be learning that contains materials based on local wisdom to prevent the loss of local wisdom from a region. This study aims to develop an e-module based on ethnoscience (local culture) for grade IX students of junior high schools/Islamic junior high schools and to determine the level of validity and practicality. The e-module developed uses the ethno-science method which consists of direct observation, explaining phenomena scientifically, and being able to draw conclusions. This research is a research and development (R&D) with the Plomp model. The validity test was conducted by 3 science lecturers from Faculty of Mathematics and Natural Sciences Universitas Negeri Padang, and the practicality test was conducted by 2 science teachers from State Junior High School 1 Painan and 3 IX.3 students, 4 IX.6 students and 20 IX.7 students at State Junior High School 1 Painan. The instruments used were validity and practicality questionnaires and data Cohen Kappa. This research produces an e-module of the human reproductive system based on ethnic with an average kappa moment of 0.90 which has a very high level of validity. The results of the teacher's practicality test and the student's practicality test obtained an average kappa moment of 0.76 and 0.81 respectively with high and very high levels of practicality.
