Abstract

This study aims were to analyze the profile of radiation intensity and sunshine duration in the karst area of Maros TN Bantimurung Bulusaraung, South Sulawesi during solstice phenomenon in the period 2011-2020. In addition, radiation intensity and sunshine duration in the same area were also measured. A Pearson correlation shows that the intensity of solar radiation and the sunshine duration have a bimodal pattern. The average radiation intensity during the 2011-2020 solstices in June and December was 1.193  and 1.249 , respectively. Whereas the percentage of sunshine duration in June and December reached 54% and 35%, respectively. The results of the Pearson correlation analysis of the relationship between radiation intensity and sunshine duration in June were 0.722, while in December, it was 0.717. The interpretation results show that the two parameters have a strong correlation and have a close relationship

Abstract

Subdistrict Galesong is lying areas and coastal areas with an altitude of 0-100 meters above sea level. This spurred the use of land for the functional area awakened. Based on this case, it is necessary to conduct research on seismic vulnerability distribution in Kecamatan Galesong of Takalar Regency. Primary data are taken directly around the north coast Galesong using 303S TDL. The data taken as much as 5 points of measurement with the distance of each point about 500 meters. Further data measurement is then processed with Geopsy software. The frequency value is 0,416-0,509 Hz hence the dominant alluvial rock study location, where at point MG02 is the most vulnerable area with value 105,9918. While based on the value of PGA is 8.4-9.4 Gal, then the location of research including very small level of risk of earthquake.
