Abstract

Future sea level rise in North Jakarta is one of the potential hazards that threaten the safety of coastal communities and infrastructure. Prediction of sea level rise is needed to reduce the vulnerability of the people living on the coast. This study was conducted to estimate the height of sea level rise in 2045 using linear regression analysis of hourly tidal data for 2013-2021 coupled with the highest astronomical tide value from the results of tidal harmonic analysis in 2021 using the t_tide application in matlab. The water elevation was then projected on the Digital Elevation Model to obtain the inundation area in 2045. The result of this study is an inundation area of 56 km2 in North Jakarta in 2045 due to an increase in total sea level of 117 cm at high tide.

Abstract

Due to the rapid growth of motorized vehicles, Surabaya City faces significant challenges related to traffic congestion and greenhouse gas (GHG) emissions. This growth harms air quality and worsens climate change. Therefore, finding practical solutions to reduce GHG emissions in the transportation sector is important. One potential solution is the implementation of an Intelligent Transport System (ITS), which can improve traffic management and transportation efficiency. This study aims to evaluate the effectiveness of ITS implementation in reducing GHG emissions in Surabaya City. The research methods used include primary data collection through interviews and questionnaires and secondary data obtained from official reports and the implemented ITS system. The analysis was carried out by considering three main aspects: technical, environmental, and institutional, using the CLIMACT Prio method to determine the priority of appropriate mitigation actions. The study's results indicate that implementing an Intelligent Transport System (ITS) in Surabaya City can reduce greenhouse gas (GHG) emissions through several main approaches. ITS optimizes traffic management by reducing congestion and idle time, reducing emissions. In addition, ITS increases the use of public transportation and supports the integration of environmentally friendly vehicles, such as electric vehicles, which reduce dependence on fossil fuels.

Abstract

The Muara Karang Generation Unit in North Jakarta is located in a coastal area that is highly vulnerable to climate change, particularly due to rising ambient air temperatures, sea-level rise, and coastal inundation. These impacts have affected the plant’s operational performance, including reduced efficiency of gas and steam turbines, increased cooling system loads, and the occurrence of seawater intrusion within the power plant area. Such conditions have the potential to disrupt the reliability of electricity supply to the strategic areas of DKI Jakarta. Therefore, a comprehensive climate vulnerability assessment is required to evaluate the level of risk, as well as the technical and financial implications of climate change on power plant performance. This study employs the Climate Vulnerability Index (CVI) approach, which comprises three components: exposure, sensitivity, and adaptive capacity. Exposure analysis was conducted using historical data on ambient air temperature, sea surface temperature, and sea-level rise for the 1994–2024 period, along with CMIP6 climate projections for 2026–2060 under the SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios. Sensitivity was assessed based on reductions in generation capacity due to increased air and seawater temperatures, higher fuel consumption, and the risk of seawater intrusion. Adaptive capacity was evaluated through an assessment of existing climate change adaptation and mitigation measures implemented at the facility. All indicators were normalized and weighted to produce a composite vulnerability index value. The results of the climate vulnerability assessment, based on the parameters of ambient temperature, sea temperature, and sea-level rise at the Muara Karang Power Generation Unit, show index values of 0.36 in 2030 and 0.45 in 2050, corresponding to “low” and “moderate” vulnerability categories, respectively.

Abstract

PLTA pumped storage berperan penting dalam menjaga keandalan sistem ketenagalistrikan pada era transisi energi. Namun, kinerjanya sangat bergantung pada ketersediaan air yang rentan terhadap perubahan iklim. Penelitian ini menganalisis curah hujan historis dan proyeksi curah hujan di DAS Grindulu sebagai dasar evaluasi ketersediaan air reservoir PLTA Grindulu pumped storage. Data curah hujan Stasiun Tegalombo periode 2015–2024 dianalisis, sedangkan proyeksi hingga 2100 menggunakan skenario SSP2-4.5 dan SSP5-8.5 dengan koreksi bias Quantile Delta Mapping (QDM). Hasil menunjukkan curah hujan memiliki variabilitas antartahun yang tinggi, dengan rata-rata tahunan 2182 mm dan standar deviasi 720 mm. Metode QDM efektif mengurangi bias model, ditunjukkan oleh PBIAS yang umumnya berada dalam rentang ±15%, nilai MAE yang stabil, dan RMSE yang konsisten antardekade. Proyeksi jangka panjang menunjukkan peningkatan curah hujan tahunan pada kedua skenario, dengan ketidakpastian lebih besar pada SSP5-8.5 setelah pertengahan abad. Temuan ini menunjukkan bahwa perubahan iklim dapat memengaruhi ketersediaan air reservoir dan keandalan PLTA pumped storage, sehingga diperlukan perencanaan yang adaptif.

Abstract

Perubahan iklim dapat mengubah pola curah hujan dan rezim aliran sungai, sehingga memengaruhi ketersediaan air bagi PLTA pumped storage. Penelitian ini menganalisis ketersediaan air masa depan pada Upper Cisokan Pumped Storage Hydropower Plant (UCPS), proyek pumped storage berskala besar pertama di Indonesia. Pendekatan yang digunakan mengintegrasikan proyeksi iklim dan pemodelan hidrologi. Data historis dan proyeksi diperoleh dari CHIRPS, CHIRTS, dan model EC-Earth3 NEX-GDDP-CMIP6 dengan skenario SSP245 dan SSP585. Koreksi bias dilakukan menggunakan Linear Scaling dan dievaluasi dengan MBE serta PBIAS. Simulasi hidrologi dikembangkan dalam HEC-HMS dan dikalibrasi terhadap debit observasi. Ketersediaan air dievaluasi melalui Flow Duration Curve, keandalan bulanan debit harian, durasi low-flow spell, dan neraca air tampungan aktif dengan ambang operasi 0,75 m³/s. Hasil menunjukkan bahwa pada periode historis, debit harian umumnya melampaui ambang kebutuhan minimum. Pada periode proyeksi, SSP245 dan SSP585 menunjukkan peningkatan frekuensi serta durasi debit rendah. Dampak terbesar terjadi pada SSP585, dengan kejadian debit rendah hingga sekitar setengah tahun yang menurunkan volume tampungan aktif. Temuan ini menegaskan bahwa ketahanan UCPS sangat bergantung pada pengelolaan debit rendah yang panjang dan berulang.
