Abstract

Background: Land cover change is an ongoing phenomenon with significant impacts on the environment and human quality of life. An analysis of land cover change was conducted in the Magelang area, which includes both Magelang Regency and Magelang City, over a period of fifteen years from 2007 to 2023. This study aims to analyze these changes using spatial methods based on land cover maps from 2007 and 2023. Method: In this analysis, land cover was classified into five categories: settlements, dry fields, paddy fields, forests, and plantations, and then compared between the two years. Result: The analysis results demonstrate a significant increase in the area of settlements and dry fields, reflecting urban and rural development. On the other hand, there has been a decrease in the area of paddy fields and forests, which may be related to land conversion for industrial or infrastructure purposes. The change in the area of plantations was not significant, indicating continuity in the management of these lands. Conclusion: The findings of this study provide valuable insights into the dynamics of land cover change in the region and can serve as a basis for further actions to maintain a balance between development and environmental conservation.  Novelty/Originality of this study: This study presents the first longitudinal spatial analysis of land cover changes over 15 years (2007–2023), revealing significant trends in urban and rural land use dynamics. This study provides a scientific basis for sustainable spatial planning by highlighting the urgency to balance development infrastructure with preserving farmland and forests.

Abstract

Background: The global responsibility to reduce greenhouse gas emissions forces Indonesia to evaluate its energy policies and strategies. The energy mix dilemma in Indonesia arises as a consequence of rapid economic growth, rapid urbanization, and the continuously increasing energy demand. By 2060, Indonesia aims to have an energy mix dominated by renewable energy sources (RES) and to reduce its dependence on fossil fuels. The importance of reducing greenhouse gas emissions is becoming increasingly apparent, considering Indonesia is one of the countries highly vulnerable to climate change. Method: This study employs a combined approach of policy analysis and literature review. The method used in this research is an objective narrative literature review as a reference for conducting the literature study. Findings: In 2023, Indonesia is still heavily reliant on fossil fuels, primarily coal, oil, and natural gas. The Indonesian government has enacted several regulations related to energy use, including policies for the development of renewable energy. Despite efforts to reduce emissions through the application of clean technologies, the main challenge is significantly replacing fossil energy sources with renewable energy. Several inhibiting factors emerge as real challenges in the journey to achieve Net Zero Emissions. Technological and infrastructure constraints are the main obstacles. The strategic importance of sustainable economic growth is a central point in this dilemma. However, the transition to net zero emissions often requires structural adjustments that can impact the economy. Conclusion: The process of transitioning to renewable energy must be carefully implemented to avoid the risk of supply instability. The alignment between economic growth, energy security, and emission reduction is key to designing effective and sustainable policies. Novelty/Originality of this Study: This study provides a comprehensive examination of Indonesia's energy mix dilemma in the context of achieving net zero emissions by 2060, specifically highlighting the intricate balance between sustainable economic growth, energy security, and global climate commitments. By adopting a holistic approach that involves the government, private sector, and societal participation, the research offers innovative policy recommendations for transitioning from non-renewable to renewable energy sources while addressing socio-economic challenges.

Abstract

Background: Limestone mine reclamation by Limited Liability Company (LLC)/Perseroan Terbatas (PT) Semen Tonasa is carried out periodically to restore land conditions sustainably. The reclamation was carried out through revegetation using endemic plants, namely the bitter plant (Vitex colossus R.), which grows significantly in the southern part of Sulawesi. This study aims to determine the erodibility of the soil in limestone mine reclamation land planted with bitti plants. Methods: The method used is the survey method by determining the location of soil samples using the purposive sampling method based on the reclamation age planted with bitti plants in 2019, 2015 and 2010 and determining the erodibility value using the formula according to Wischmerier and Smith (1978). The parameters used included soil texture, structure, organic matter, permeability, pH, and unit weight. Findings: The results of this study indicate that the erodibility of the soil in the limestone mine reclamation land planted with bitti plants is classified as high due to the high dust content, which is influenced by the parent material. The results of this study indicate that the erodibility value of the land reclamation in 2019 was classified as moderately low to moderately high, the land reclamation in 2015 was classified as moderate to moderately high, and the land reclamation in 2010 was classified as moderate to high. Conclusion: The factor affecting the erodibility of the soil in the reclamation area is the M value (percentage of very fine silt and sand). Novelty/Originality of this Study: This study's novelty lies in examining soil erodibility changes over different reclamation ages in a limestone mine using endemic bitti plants. This research highlights the unique relationship between reclamation age and soil properties, contributing valuable insights into effective land reclamation practices in tropical karst environments.
