Abstract

The world’s attention to climate issues is increasing as the issue of global warming and climate change emerges. Several studies with the scope of cities and urban areas concluded that urban surface temperatures have an increasing trend. This phenomenon will have an impact on the thermal comfort of urban population. Yogyakarta City as one of the National Activity Centers (PKN), is experiencing rapid urban development and leads to become a metropolitan city so it needs to be studied regarding its thermal comfort. This research is intended to identify the potential and vulnerability of thermal discomfort in Yogyakarta City. The identification of potential discomfort is carried out using the Discomfort Index (DI) approach and the Land Surface Temperature (LST) value. Meanwhile, vulnerability is identified in the social aspects of population. Furthermore, the potential and vulnerability scores are assessed to get an overview of thermal discomfort mitigation priorities. Based on DI analysis, thermal discomfort is felt by more than 50% of the Yogyakarta’s residents and it is estimated that in the future will get worse. By looking at the distribution of LST values, the high potential for discomfort is in the city center and has expanded to the north and northeast. Meanwhile, areas with high vulnerability are located in the center and south side of Yogyakarta City. From the combined assessment of threat and vulnerability, the areas that are the top priority for mitigation are in the center of Yogyakarta City, which include 7 districts, namely Danurejan, Gedongtengen, Gondomanan, Jetis, Kraton, Ngampilan, and Pakualaman. The medium priority districts are Gondokusuman and Wirobrajan.

Abstract

Ogan Ilir District is one of South Sumatra, Indonesia’s regencies, prone to forest and land fires. This study aims to identify hotspot distribution and analyze fire and land hazard levels from 2017 to 2022 in Ogan Ilir District using Landsat 8 imagery with the Normalized Burning Ratio (NBR) method. The study’s results show that from 2017 to 2022, 423 hotspots were recorded. Specifically, in 2017, there were 2 points; in 2018, 121 points; in 2019, 207 points; in 2021, 76 points; and in 2022, 17 points. North Indralaya is the sub-district with the highest level of forest and land fire vulnerability, with the number of events ranging from 80 to 164. West Pamulutan and Pamulutan are at a high hazard level, with incidents ranging from 33 to 79. Meanwhile, Indralaya and South Indralaya sub-districts have a medium level of danger, with events ranging from 19 to 32. The low threat level for forest and land fires is spread across all sub-districts in Ogan Ilir District, with the number of events ranging from 1 to 18.

Abstract

Enim river flows within several sub-districts in Muara Enim Regency, including Semendo Darat Laut, Semendo Darat Tengah, Semendo Darat Ulu, Tanjung Agung, Lawang Kidul, and Muara Enim. This study examines changes in the water quality of the Enim River due to domestic wastewater discharges and the presence of the coal mining industry and household industries. Water samples were taken from 4 sampling stations along the Enim River in 2018 and 2023. Data consisted of results of physical, chemical, and microbiological parameters. The status of river water quality was assessed from the pollution index. The results of Enim River surface water quality measurements showed that the parameters of total suspended solids, Dissolved Oxygen, iron (Fe), copper (Cu), oil, and grease concentrations had breached the criteria set for Class II water quality, referring to Government Regulation of the Republic of Indonesia Number 82 of 2001. The results showed that there has been a change in the water quality status of Enim River from 2018 to 2023. The river water pollution index was (1.43-2.47) in 2018 and (1.49-3.85) in 2023 (lightly polluted). Comprehensive water treatment and preventive measures are necessary to manage and mitigate additional pollution in the Enim River.

Abstract

In the sixth assessment report, the IPCC indicates that global temperature increased by 1.11 (±0.13) degrees Celsius in 2019 due to 6.5 gigatons of CO2eq of greenhouse gas emissions into the atmosphere. The power sector is a major global greenhouse gas emitter, particularly in Indonesia. Indonesia’s electricity sector emitted 149.90 million tons of CO2eq greenhouse gas in 2020, which is expected to increase to 158.30 million tons of CO2eq in 2021. Indonesia has committed to reducing greenhouse gas emissions according to the Paris Agreement. The Paris Agreement has been ratified into national law, accommodating Indonesia’s roadmap to net zero by 2060. The emissions reduction target was published in 2022 through the enhanced Nationally Determined Contribution (NDC). This study aims to analyze the impact of climate policy in Indonesia’s electricity sector to meet the net zero emissions target by 2060. Projection and calculation in this study were conducted using the Low Emissions Analysis Platform (LEAP). Data from 2020, including electricity demand, existing capacity, energy production, energy intensity, lifetime, and capacity factor, were used to support LEAP analysis. The data were obtained from the PLN statistical book, PLN sustainability report, Indonesia’s statistical book, and climate change mitigation and adaptation reports in Indonesia. This study developed three climate scenarios, including business as usual (BAU), sustainable development (SD), and low-carbon development (LCD). These scenarios draw upon current climate policies that have various impacts on electricity generation in Indonesia. Based on LEAP analysis, by 2060, energy demand is expected to increase to 300.36 MTOE (BAU), 200.93 MTOE (SD), and 76.97 MTOE (LCD). Consequently, each climate scenario requires an increase in installed capacity to 821.82 GW (BAU), 727.06 GW (SD), and 334.58 GW (LCD). The renewable energy mix is projected to be 21% (BAU), 69% (SD), and 100% (LCD). Each scenario requires investment to develop capacity to meet energy demand. The investment cost is estimated to be 1,671.58 million USD (BAU), 1,537.64 million USD (SD), and 816.51 million USD (LCD). GHG emissions are projected to rise to 1,746.31 million tons of CO2eq (BAU) and 264.39 million tons of CO2eq (SD). However, the LCD scenario expects to achieve net zero emissions by 2060.

Abstract

Community-based waste management in the PT. Bukit Asam Township, Tanjung Enim, is essential. This study involved 67 respondents residing in the Township. A mixed-method approach was used, including interviews, observations, and SWOT analysis. The results indicate that residents are actively engaged in waste containment, with most households (85%) disposing of all waste without sorting. Only a small percentage reuse items (5%) and compost (2%). The average waste generated per socioeconomic group exceeds the standards set by SNI 3242-2008. Community-based waste management at PT. Bukit Asam has the potential for success due to active participation and company support. The SWOT analysis reveals strengths in participation, company support, education, and a structured system but weaknesses in dependence on participation and funding, and limitations in human resources and infrastructure. Opportunities include government support, new technologies, and collaboration with NGOs, while threats arise from policy changes, social issues, regulations, environmental impacts, and disasters. Improvement strategies include initial assessments, stakeholder mapping, awareness enhancement, facility provision, supervision, monitoring, incentives, periodic evaluations, and continuous innovation. With these strategies, the program is expected to be effective and sustainable, address waste issues, create new economic opportunities, and serve as a model for other communities.
