Abstract

This research aims to evaluate the potential for wind energy in Kolaka Regency using ERA5-Land reanalysis data from the output of the European Center for Medium-Range Weather Forecasts (ECMWF) model, which has a spatial resolution of 9 km with hourly temporal resolution for the period of 2001 to 2020. This research also compared the quality of ERA5-Land reanalysis wind speed data on data from nearby meteorological stations using statistical assessment methods. The analysis results reveal that the highest average wind speed is discovered at a height of 80 to 150 meters with a range of 4.99 to 5.93 m/s. The spatial distribution map of wind power density indicates that the energy potential at a height of 80 to 150 meters can reach 60 to 170 W/m2. The largest wind energy potential in Kolaka Regency can be generated in the DJF period (December-January-February) with the highest average monthly wind power density in January and the JJA period (June-July-August) with the highest average in July. In general, Kolaka Regency can be classified as an area with first-class wind energy potential, so it tends to be more suitable for the development of small-scale power plants. The suitable locations for developing small-scale wind power plants in Kolaka Regency are the southern Pomalaa coast and the Tanggetada coast because both locations have better wind energy sources than other areas.

Abstract

This study aims to determine changes in the components of wind direction and speed during tropical cyclones by utilizing the ECMWF Era-Interim Reanalysis model data analyzed in the form of a time series graph. In addition, to determine the effect of the Dahlia Tropical Cyclone on changes in sea level on the Lampung Coast, a study was conducted by simulating sea level changes using the Delft-3d hydrodynamic model during the tropical cyclone event. The method used is comparative by comparing the output of hydrodynamic models to tidal measurements at 2 research points, namely Krui and Kota Agung tides. The data used are FNL wind data with a grid resolution of 0.25⁰ x 0.25⁰ and bathymetry data from gebco with a resolution of 30 seconds. The results showed that the performance of the hydrodynamic model was able to represent sea level well where the RMSE value was 0.36 for Krui Pasut Station, 0.23 for Kota Agung Pasut Station. While the correlation coefficient for Krui Pasut Station is 0.87 and 0.82 for Kota Agung tide station.
