Abstract

Global warming, driven by escalating atmospheric carbon dioxide CO₂ concentrations, represents a critical threat to global climate stability and exacerbates extreme weather events. Indonesia, particularly East Kalimantan and its capital, Samarinda City, serves as a significant contributor to these emissions due to intensive land-use and land-cover changes (LULCC), primarily characterized by deforestation and the rapid expansion of coal mining. The primary objective of this study is to explicitly quantify the rate of land-use conversion and evaluate its direct implications for terrestrial carbon stocks in Samarinda City over a decadal period from 2014 to 2024. To achieve this, the research utilizes high-resolution Landsat 8 OLI/TIRS satellite imagery processed through Geographic Information Systems (GIS) and Google Earth Engine for temporal change detection. Carbon stocks were quantified using the ICLEI carbon calculator by integrating spatial transition data with biomass-based carbon indices. Key findings reveal a substantial decline in the city's total carbon stock, falling from 1,630,212.52 tons in 2014 to 1,442,812.07 tons in 2024. This depletion is fundamentally linked to a 65.22% expansion of mining areas. The results underscore the urgent need for integrating strategic zoning within the Regional Spatial Plan (RTRW) and adopting advanced carbon mineralization technologies to mitigate further carbon stock loss.

Abstract

Rapid urban growth and increasing waste generation in Pangkalan Kerinci have intensified pressure on the Kemang Final Disposal Site, which is nearing full capacity. To address this issue, an integrated approach combining TPS 3R (Reduce, Reuse, and Recycle) and landfill mining was proposed. This study aimed to analyze the relationship between the integration of TPS 3R and landfill mining and its effect on extending landfill operational life. The novelty of this research lies in presenting the first integrated evaluation of TPS 3R and landfill mining in Indonesia, assessing their combined efficiency in reducing waste volume and prolonging landfill lifespan. The research utilized mass balance analysis and scenario modeling to compare three different strategies: (1) no intervention, (2) TPS 3R implementation, and (3) TPS 3R combined with landfill mining. Results showed that the application of TPS 3R alone reduced landfill input by 73.32 percent, extending its lifespan to 650 days. The most optimal outcome was observed in the third scenario, in which two screening units were used during landfill mining to reclaim sufficient space within 410 working days. This duration coincides precisely with the period when the active landfill cell reaches full capacity. The integration ensures service continuity, supports circular economy practices through the recovery of Refuse-Derived Fuel (RDF), and offers a replicable framework for sustainable solid waste management in similar urban contexts.

Abstract

Tourist village is a rural area that has several special characteristics to become a tourist destination. The development of tourist villages has become an important strategy in strengthening the local economy, preserving cultural heritage, and improving the welfare of people in Indonesia, one of which is in Kediri Regency, East Java Province. Jambu Village is one of the villages and the only tourist village in Kayen Kidul District, Kediri Regency. Jambu Tourist Village is an independently managed tourist village, which has led this village to receive an award from the Governor of East Java as a Smart Mandiri Sejahtera Tourist Village (DEWI CEMARA) in October 2019. Despite its success, Jambu Tourist Village also experienced problems in its development process. Development of five tourism components (attraction, accessibility, accommodation, amenity, and ancillary) still faces many problems. The purpose of this study is to ensure sustainable tourism development by aligning the expectations of the community and visitors with the quality of service. Many issues remain persistent, particularly in the areas of public transportation, road infrastructure, and pedestrian facilities. To address these challenges, this study aims to measure the level of alignment between tourist satisfaction and the importance of various tourism components using the Importance-Performance Analysis (IPA) method. The results show a level of conformity of 68.97%, with 16 attributes falling into critical Quadrant I, indicating immediate priority for improvement. These results emphasize the need for strategic intervention to improve the overall quality of tourism services in Jambu Tourism Village.
