This study aims to formulate a sustainable reclamation management strategy using the MICMAC (Matrix of Crossed Impact Multiplications Applied to a Classification) approach in Pinang Raya District, North Bengkulu Regency. Mining activities in this region have caused ecological degradation, making post-mining land reclamation crucial. The research employs a qualitative method with data collection through field observations, questionnaires, and interviews involving stakeholders from mining companies, plantation companies, and local communities. The MICMAC analysis identified key driving factors in sustainable reclamation, such as regulatory enforcement, personnel management, public understanding, and community participation. The study results show that sustainable reclamation requires integrated planning involving strengthened legal frameworks, capacity building, and participatory approaches. Strategies should prioritize technical implementation (land arrangement, topsoil distribution, and local vegetation planting) and social inclusion to ensure ecological restoration while enhancing community welfare. This approach contributes to achieving the Sustainable Development Goals (SDGs) and offers a reference for sustainable post-mining land management in Indonesia.

Global shark populations have declined drastically due to intense fishing pressure, including in Tarakan, North Kalimantan—a key landing area with limited data on species diversity and conservation status. This issue is exacerbated by the use of non-selective fishing gear such as mini trawls, which result in significant shark bycatch. This study aims to identify shark species caught as bycatch and assess their conservation status. Data were collected from March to May 2025 through field observation and morphological identification. Five shark species were recorded: Chiloscyllium plagiosum, Chiloscyllium punctatum, Hemigaleus microstoma, Sphyrna lewini, and Rhynchobatus austraiae, totaling 145 individuals. The Shannon-Wiener diversity index (H' = 1.35) indicates moderate diversity, with S. lewini being the most dominant. According to the IUCN Red List, two species are Critically Endangered (CR), one Vulnerable (VU), one Near Threatened (NT), and one Least Concern (LC). These findings highlight Tarakan waters as a critical habitat for threatened shark species and emphasize the urgent need for sustainable fisheries management based on blue economy principles, including bycatch reduction, fisher education, and development of conservation-based economic alternatives. Keywords: sharks, bycatch, conservation status, Tarakan, blue economy

Mining activities can cause environmental degradation, especially in the form of changes in land cover and loss of vegetation. Therefore, monitoring the success of reclamation is important to ensure the restoration of post-mining ecosystems. This study aims to (1) monitor the implementation of post-mining land reclamation of PT. Bukit Sunur by analyzing canopy density or vegetation cover through Landsat and Sentinel imagery using the ArcGIS 10.8 platform, and (2) compare the NDVI values from both satellite images in the 2016, 2020, and 2024 periods to see the differences in the level of reclamation success detected by each satellite sensor. This study uses a remote sensing analysis method, where Landsat and Sentinel images are processed to extract NDVI (Normalized Difference Vegetation Index) values to identify changes in vegetation density over time. Vegetation density classification is carried out using the Kappa index and Overall Accuracy (OA) calculations to measure the accuracy of image classification. The results show that the reclamation of post-mining land of PT. Bukit Sunur experienced a significant increase in vegetation density. In 2016, most of the area was still dominated by the Low to Moderate Vegetation category, but in 2020 there was an increase in the area of High Vegetation due to the transition from the Fairly High Vegetation class. Furthermore, in 2024, Very High Vegetation increased drastically from 0 ha to 267 ha, indicating the success of reclamation in improving land cover. Furthermore, a comparison of Landsat and Sentinel imagery shows a similar trend of NDVI changes, although Sentinel provides a higher resolution in detecting detailed vegetation changes. Overall Accuracy (OA) and Kappa Index (KA) values reached 97%-100%, indicating a very high level of classification accuracy. The conclusion of this study is that reclamation monitoring using satellite imagery has proven effective in identifying vegetation changes over time, with Sentinel showing superiority in more detailed resolution co mpared to Landsat. The results of this study can be used as a basis for evaluating mine reclamation programs and planning for post-mining ecosystem sustainability.

ABSTRACT The prevalence of mental health problems among urban dwellers is triggered mainly by increased urbanisation and the pressures of modern life. One solution that is now widely considered is the development of healing forests, which are green areas that serve as natural therapeutic spaces for mental and physical health. The University of Bengkulu's main campus, situated in a lush green area, has excellent potential to develop a healing forest. This study aims to analyse the potential for developing a healing forest on the Main Campus of the University of Bengkulu, including identifying suitable areas, analysing the benefits that can be generated, and recommending sustainable management and environmental conservation strategies. Through a qualitative descriptive approach, data were collected through direct observation, interviews with relevant parties, and literature review. The results showed that, after evaluation, the location that qualifies as a healing forest is only in zone 2, specifically at the point where the green area around the UNIB Rectorate is located. However, other places have the potential to be developed into a healing forest. Based on an analysis of visitors' perceptions and preferences, it is suggested that each location has the potential to be a healing forest, with several recommendations provided. Developing a healing forest on this campus is expected to be a strategic step in creating an environment that supports the psychological well-being of the academic community and provides broader ecological benefits.

Illegal Gold Mining (PETI) in Lebong Tambang Village has caused various environmental, social, and economic problems. PETI activities contribute to environmental pollution due to the use of mercury, infrastructure damage, and worker safety and health risks. This study aims to identify internal factors (strengths and weaknesses) and external factors (opportunities and threats) that influence PETI management, and to formulate appropriate strategies in implementing mining regulations. This study uses a descriptive method with SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis to determine the optimal strategy in PETI management. Data were collected through field observations and interviews with illegal miners and the Mining Inspector of the Ministry of Energy and Mineral Resources for the Bengkulu Province Region. The results of the analysis show that the main factors influencing PETI sustainability are limited regulation socialization, weak law enforcement, and high costs of the community mining legalization process. Recommended strategies include increasing mining regulation socialization, determining Community Mining Permits (IPR), and collaboration between local governments and mining companies in adjusting mining business permits. The implementation of this strategy is expected to create more sustainable mining, reduce environmental impacts, and improve community welfare. Keywords : Community Mining Permit, Environment, Illegal Gold Mining, SWOT

Land cover changes in Bengkulu City have significant impacts on carbon stock dynamics, which play a vital role in climate change mitigation. This study aims to analyze carbon stock estimates resulting from land cover changes using remote sensing technology. Landsat and Sentinel-2 satellite imagery data were used to map land cover changes over a specific period, employing a supervised learning-based classification method. Further analysis was conducted to estimate carbon stocks using calculations from the ICLEI Calculator approach. The results of the study indicate a decrease in natural land areas, such as shrubland and mixed dryland agriculture, which declined by 4,236.5 hectares and 3,002.6 hectares, respectively. The conversion of these lands into settlements, plantations, and paddy fields led to a significant decrease in total carbon stocks from 340,095.55 tons in 2014 to 279,033.7 tons in 2024. Additionally, the spatial distribution of carbon stocks in the study area showed patterns correlating with anthropogenic pressures and urban spatial planning policies. The main factors influencing these changes include urbanization, plantation expansion, and land conversion for economic purposes. This study underscores the importance of sustainable land management to prevent ecosystem degradation and support carbon stock enhancement. Conservation efforts, ecosystem rehabilitation, and prudent land-use policies are strategic steps in maintaining carbon balance and mitigating the impacts of climate change.

The lack of integration of the ecotourism management system often causes problems in the attraction aspect, resulting in a decrease in tourist visits both regionally, nationally and internationally. The main objective of the research is to develop a strategy to increase economic and environmental value in the form of integrating three coastal-based ecotourisms. The data used are primary data (qualitative data) and secondary data (quantitative data). The Bengkulu City was used as an urban-based research case with coastal characteristics. The three ecotourism objects taken are Fort Marlborough ecotourism, Kampong Cina ecotourism, and Pantai Panjang ecotourism. Data collection was carried out using in-depth interviews, observation, and documentation methods. Data analysis was carried out using descriptive analysis methods and SWOT analysis. The results of the research show that there are nine strategies that are capable of building coastal-based integrated ecotourism that is highly attractive and capable of increasing economic and environmental value, namely: formulate a grand design for the integration of three coastal ecotourism destinations appropriately; build strong coordination and synergy with various stakeholders; improve the charm of the physical form of ecotourism consistently; provide strengthening, literacy, and guidance to the community; conduct an in-depth study of the various shortcomings of the three destinations; building a positive image of integrated coastal ecotourism destinations; increasing the strength of attraction through improving the quality of representative economic facilities/facilities (culinary tourism); improving the quality of human resources in the form of training and benchmarking to increase professionalism; and conducting intensive dialogue and discussions between stakeholders.
