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.
Urban Heat Island (UHI) poses a growing environmental and public health challenge, particularly in densely populated urban areas with limited green infrastructure. High-density settlements often experience extreme thermal stress due to compact building forms, poor ventilation, and heat-retaining materials, yet lack detailed spatial data to guide mitigation efforts. This study employed UAV-mounted thermal imaging to map and analyze surface temperature distribution across two contrasting residential zones. Results showed that Zone 1, characterized by tightly packed housing and metal roofing, experienced the most severe UHI effect, with 87.64% of its area exceeding 35°C by 15:00. In contrast, Zone 2, with slightly more vegetation and open layout, recorded 83.87% above 35°C at the same time. These findings highlight the significant impact of urban morphology and land cover on thermal performance. This research contributes a high-resolution, drone-based methodology for assessing micro-scale UHI patterns, offering a practical tool for climate-responsive urban planning.
Roma Tabing Tongkok, a vernacular house of the Madurese Pendalungan community in Situbondo, reflects local adaptation to the region’s hot-dry climate. This study aimed to examine its climate-responsive features and thermal comfort performance using a mixed-method approach combining visual analysis with temperature and humidity measurements conducted over two months (October–November 2023). Results shows that the house’s linear form, natural materials, and cross-ventilation openings support climate adaptation, yet their effectiveness remains limited due to suboptimal building orientation, lack of shading, and variations in roof height that affect heat release. These findings highlight the need to integrate additional passive strategies, such as low-conductivity ceilings, vegetation as a shading, and improved opening orientation to enhance thermal comfort. Strengthening these design adaptations can help sustain vernacular architecture while offering a model for energy-efficient, climate-responsive housing in dry tropical regions.
The urban heat island (UHI) phenomenon has been detected in Malang City, defined as an urban area with a higher surface temperature than its surrounding areas. Pasar Besar Corridor is the center of trade and services as well as the Central Business District (CBD) of Malang City, located in Sukoharjo Sub-District, Klojen District. Although it is an economically strategic area in Malang City, Pasar Besar Corridor is vulnerable to high-intensity UHI exposure, so it is necessary to conduct a study related to the UHI phenomenon. This research aims to compare the results of UHI analysis between macro-scale and micro-scale analysis. Macro-scale UHI analysis was performed using Landsat-8 data as input for Land Surface Temperature (LST), while micro-scale UHI analysis utilized UAV thermal imaging. The results of the analysis show that while Pasar Besar Corridor is not considered a hot spot in Sukoharjo Village at the macro-scale level, a micro-scale UHI has occurred in Pasar Besar Corridor, with the roads being the hot spot, or “heat islands," reaching 48.62 °C. There is a significant difference between the highest temperature from UAV thermal imaging and LST, caused by the differences in resolution and altitude between Landsat-8 data and UAV data. From this research, it is concluded that LST is more suitable for larger study areas, while UAV thermal imaging is better suited for small-scale and more detailed analysis. However, each tool has its limitations, such as lower detailed accuracy for LST and higher costs for UAV thermal imaging.
One of the busiest locations of Bukittinggi is the Jam Gadang region, which is distinguished by land use areas that are mostly used for trade, services, and tourism. This area's level of appeal is not directly correlated with the amount of urban infrastructure, such as pedestrian walkways, which are abused by shopkeepers or street vendors who set up shop along them and by motorized vehicle users who park illegally on them, endangering the safety of both pedestrians and vehicle users. This study aims to examine the factors of familiarity and warmth in the Jam Gadang area. The warmth component is analyzed by determining the distinctiveness of the Jam Gadang area through its physical, social, and historical appeal. The familiarity component is examined by considering the features and effectiveness of on-street parking in the Jam Gadang area, as well as the number of public transportation options available. While the familiarity aspect of on-street parking will be studied using Important Performance Analysis (IPA) to assess service performance, and then followed by Quality Function Deployment (QFD) analysis to determine the priority of enhancing on-street parking performance, the warmth aspect will be analyzed using descriptive analysis. Frequency distribution analysis will be used to examine the familiarity factor of interacting public transportation users. The findings demonstrate the importance of managing the pedestrian path in the Jam Gadang area by incorporating the Omotenashi concept, which emphasizes familiarity and warmth. Physical attractiveness is highest on Ahmad Yani street, which has a total attractiveness value of 93, is characterized by the variety of building functions on this road.
