Abstract

Climate change is a global issue that affects various sectors, including the electricity sector, with one of the impacts of climate change being the increased risk of landslides influenced by rainfall, land use, slope gradient, and soil type. This research aims to assess the landslide risk in East Kalimantan on electricity infrastructure and formulate adaptation strategies for these landslides. The research method is a quantitative analysis and spatial approach by combining historical data and climate projections up to the year 2060 using the CMIP6 dataset scenarios SSP2-4.5 and SSP5-8.5. Data processed using Geographic Information System (GIS) to produce landslide risk maps for both current conditions and projections. The determination of adaptation strategies is carried out through a combination of SWOT Analysis and Analytical Hierarchy Process (AHP) methods. This research shows that the projection of landslide risk class areas in most parts of East Kalimantan is predominantly in the moderate risk class with an area of 58.16% and the high-risk class with an area of 26.43%. The priority strategies for landslide adaptation in the development of electrical infrastructure are chosen based on the analysis of three aspects: the optimization of DPT development and other supporting technologies in a planned and integrated manner, the preparation of a roadmap for prioritizing the reduction of extreme operational risk points as part of efforts to adapt to the projected increase in landslide risk, and the utilization of evaluation results from periodic monitoring and field inspections to support risk-based electrical infrastructure development planning.

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.
