Abstract

Nickel mining in Weda, Halmahera Island, is one of the largest nickel mines in Indonesia, and its activities impact changes in vegetation indices and cover in the area. The research uses Landsat 8 satellite imagery from 2019, 2022, and 2025 with the NDVI algorithm to analyse changes in vegetation index values and vegetation cover. The research results show that the NDVI values for 2019 are the lowest at -0.233774 and the highest at 0.999903; for 2022, the lowest is -0.369486 and the highest is 0.799867; and for 2025, the lowest is -0.369486 and the highest is 0.530372. The NDVI values were then classified into 4 vegetation cover classes: active mining areas, sparse, moderate, and dense vegetation. The active mining area in 2019 was 1.27 km², in 2022 it was 11.91 km², and in 2025 it was 18.20 km². Sparse vegetation in 2019 covered 5.73 km², in 2022 it covered 6.03 km², and in 2025 it covered 8.07 km². Moderate vegetation in 2019 covered 5.72 km², in 2022 it covered 2.68 km², and in 2025 it covered 2.21 km². Dense vegetation in 2019 covered 522.64 km², in 2022 it covered 515.35 km², and in 2025 it covered 507.20 km². The presentation of the mining area continues to increase every year. The results of this research are expected to be used for continuous monitoring to ensure compliance with environmental standards and support rehabilitation programmes in Weda and other tropical mining areas.

Abstract

The increasing demand for land due to population growth and community activities in Ambon City certainly has an impact on land cover changes in the Waiheru Watershed. Therefore, it is important to model future land cover as a sustainable environmental planning material. This study aims to analyze land cover changes in 2014, 2019, 2024 and model land cover in 2034 with the Cellular Automata Markov Chain (CA-Markov) approach. This method integrates historical land cover data and factors driving land use change, elevation, slope, distance from road, distance from river, population, distance from point of interst. The results show a trend of conversion of mixed agricultural land into residential areas, which certainly has the potential to exacerbate ecosystem vulnerability in the Waiheru watershed. Settlement land cover continues to increase in area, namely 68.78 ha in 2014, 77.73 ha in 2019, 96.72 ha in 2024 and the modeling results in 2034 show that settlement land has an area of 138.65 ha, this is in contrast to the forest area which has decreased due to the expansion of population settlements.These findings are expected to provide insights for policy makers and urban planners in formulating sustainable land management strategies, as well as maintaining a balance between development needs and environmental conservation in the Waiheru watershed.

Abstract

Obi Island in North Maluku Province, Indonesia, has undergone significant land cover changes due to the expansion of nickel mining activities, especially since official operations began in 2010; the conversion of built-up land and vegetated areas into mining and settlement zones has increased pressure on land carrying capacity and contributed to more frequent flooding during the rainy season. This study uses spatial analysis based on Landsat 5 (1995) and Landsat 8 OLI (2025) satellite imagery to map land cover changes over three decades. The results show an increase in built-up land area from 448.84 hectares to 698.67 hectares, as well as the emergence of a 4,963.67-hectare mining area in 2025, while open land, water bodies, and vegetation have significantly declined. These findings demonstrate the direct impact of mining activities on landscape dynamics and the local environment, necessitating sustainable management and mitigation measures to maintain ecological balance and reduce the risk of related disasters.Keywords: LULC, Nickel Mining, Obi island
