Abstract

The mining industry has an important contribution to the economy and regional growth, but it also has the risk of environmental disturbance, so it is required to carry out reclamation. A special strategy is needed for the success of reclamation can improve the quality of life of the community and other organisms. The purpose of this research is to examine successful mining reclamation methods that can be implemented. This study uses a qualitative approach through social observation, questionnaires, in-depth interviews, and a literature review. Reclamation by PT. X consists of programs for the preparation, planning, implementation and management of reclamation areas. At the preparation stage PT. X conducts public consultations to listen to suggestions, opinions and responses from local communities, especially land owners who are rent. PT. X applies the participatory-accommodative principle. This strategy puts forward a bottom-up mechanism, namely the local landowners provide advice to PT. X related to the type and implementation of reclamation and PT. X conducts verification as well as careful and in-depth studies of technical implementation. Reclamation needs to be managed by providing an enclave zone that acts as a center for mining environmental protection. The area of the enclave zone should ideally be determined based on consideration of the area of the IUP, ecosystem typology, diversity, evenness and distribution of flora and fauna, as well as total carbon emissions. Just and prosperous reclamation is carried out by considering the existence and proper allocation of space for abiotic and biotic components including sources of livelihood for local communities.

Abstract

The transition to sustainable transportation is critical to global efforts to mitigate climate change and reduce environmental degradation. Life cycle assessment (LCA) provides a comprehensive framework for evaluating the environmental impacts of various vehicle technologies throughout their entire life cycle. Numerous studies have applied cradle-to-gate, cradle-to-wheel, and cradle-to-grave approaches. However, increasing material waste from vehicles and batteries is expected to become a significant environmental challenge due to intensive mining and resource extraction activities. To address this issue, the cradle-to-cradle approach is proposed to mitigate environmental impacts during the end-of-life phase through material recycling and recovery. This study examines manufacturing, operational, and end-of-life phases across various vehicle technologies. Unlike traditional cradle-to-grave assessments, the cradle-to-cradle approach promotes resource circularity by integrating material reuse and recycling into the evaluation process, thereby minimizing waste and optimizing resource efficiency. The analysis identifies critical indicators, including energy consumption, air quality, and greenhouse gas (GHG) emissions. Although electric vehicles (EVs) significantly reduce operational emissions, they present challenges related to battery material extraction and end-of-life management. By incorporating cradle-to-cradle principles, this study highlights strategies to enhance material recovery and reusability, particularly for battery components and lightweight materials. Furthermore, this research underscores the importance of adopting renewable energy sources and circular economy principles in the transportation sector to achieve sustainability goals. Policy recommendations include strengthening recycling infrastructure, incentivizing eco-friendly vehicle design, and fostering cross-sector collaboration. The findings contribute to a deeper understanding of sustainable vehicle technology pathways and provide a framework for reducing environmental impacts while meeting growing transportation demands.

Abstract

This study addresses the persistent environmental challenges associated with coal mining in tropical and subtropical regions, where complex microclimates and ecological variability hinder effective reclamation. Despite the increasing global coal demand, comparative cross-country insights remain limited. This research fills the gap by evaluating the best practices. This study employs a qualitative methodology with a comparative case study design, uses systematic literature review to evaluate ecology based reclamation policies and implementation practices. Data were sourced from peer-reviewed journals from Scopus and the Web of Science database and institutional reports, and analyzed using McHarg’s landscape ecology theory to evaluate reclamation policies, ecological challenges, and implementation practices. The results reveal that while all four tropical coal-producing countries possess clear regulatory frameworks for reclamation, their effectiveness varies due to ecological, climatic, and enforcement disparities. Australia demonstrates the most successful model, integrating strict policies with advanced technology and sustainable financing. Conversely, Colombia, Indonesia, and South Africa face challenges in enforcement and consistency. Thematic analysis from Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), shows that research is dominated by ecological and biodiversity aspects (44 articles), followed by reclamation technologies (22), economic-social factors (8), and regulatory studies (3). Aligning with McHarg’s landscape ecology theory, the study finds that successful reclamation hinges on site-specific ecological strategies, that are responsive to microclimates and landscape typologies. Technologies such as overburden non-acid forming (OB-NAF) encapsulation and electrodialysis reflect the ecosystem-based approach. However, future research must include empirical validation and community participation to strengthen long-term reclamation success and ecological resilience.

Abstract

Yogyakarta's landscape is known for having experienced drought hazard. At the same time, there is a native tropical tree that has the ability to store the water and cope with the emerging drought. In this regard, this study is aiming to evaluate the potential distribution of the tropical native gayam forest tree (Inocarpus fagifer Forst.) to cope with the drought in the Yogyakarta landscape. Samplings of I. fagifer covered four districts (Sleman, Kulonprogo, Bantul, and Gunung Kidul) and one city (Yogyakarta City) and implemented from January to March 2025. The potential distribution was estimated using MaxEnt. The drought was estimated using remote sensing. The resulting model gained an AUC of 0.804, confirming that I. fagifer can adapt to low rainfall and has the potential to inhabit areas with drought. Bantul, Sleman, and Kulonprogo were districts where the I. fagifer potential distribution areas exceeded almost five to seven times the drought areas. This information can be used as a baseline and recommendation from village to district levels to start to mainstream and disseminate the planting of tropical native trees as a nature-based solution to cope with the drought hazards across Yogyakarta's landscape.

Abstract

The intensive use of pesticides in agriculture has raised concerns regarding environmental quality and economic sustainability, particularly in Parongpong District, West Bandung Regency. This study aimed to analyze the impact of pesticide use on soil and water quality as well as its economic implicates on farmers. A mixed-method approach was applied through soil and surface water sampling, laboratory analysis, and structured questionnaires with 100 farmers. Soil quality tests revealed low pH, reduced organic carbon (1.61%), and high cadmium (5.2 mg/kg), indicating soil degradation. Water samples from the Cibeureum River showed that BOD (93.5 mg/L), COD (302 mg/L), and total phosphorus (0.475 mg/L) exceeded national standards, suggesting nutrient overload and pollution linked to pesticide runoff. Economically, although 98% of farmers perceived pesticides as beneficial, the Benefit-Cost Ratio (BCR) analysis resulted in a value of 0.57, implying financial inefficiency. This indicated that the cost of pesticides and mitigation outweighs the actual benefits received from increased crop yields. The gap between farmers’ perception and objective economic and environmental data highlights the need for sustainable solutions. Organic farming practices introduced by local farmer groups, such as Semai Organik and Farm Organic Parongpong, offer promising alternatives for improving productivity while preserving environmental integrity. Promoting environmentally friendly farming methods is essential to ensure long-term ecological balance and economic resilience in the agricultural sector.
