Abstract
Telah dilakukan analisis percepatan tanah maksimum di area Kantor BMKG, Tretes, Jawa Timur. Penelitian ini digunakan untuk menentukan persebaran nilai percepatan tanah maksimum yang ada di daerah tersebut. Wilayah penelitian ini berada pada Lintang -7.66 dan Bujur 112.6. Dilakukan pengambilan data di area kantor BMKG Tretes sebabnyak 5 titik dan data sekunder gempabumi dari tahun 1967 - 2016 dari United States Geological Survey (USGS) yang terdapat 823 kejadian gempa bumi. Hasil didapatkan nilai percepatan tanah maksimum di area Kantor BMKG Tretes dengan rentang nilai dari yaitu 25,7 gal dan sampai yang tertinggi 26,7 gal. Untuk Periode dominan menurut Kanai termasuk jenis II di karena nilai f0 di rentan nilai 4, yang termasuk jenis ketebalan sendimen permukaannya kategori menengah dengan ketebalan 5-10 meter. Untuk Frekuensi Dominan mendapatkan rentan nilai di 0,2 Hz yang dapat dikatakan dalam karakter yang keras.
English Abstract
The peak ground acceleration analysis has been done in BMKG Office area, Tretes, East Java. This research is used to determine the spread peak ground acceleration value in the area. The study area is located at Latitude -7.6 and Longitude 112.6. Data were taken in BMKG Tretes office area for 5 dots and secondary data of earthquake from 1967 - 2016 from United States Geological Survey (USGS) which was 823 earthquake events. The results obtained the peak ground acceleration value in the area of BMKG Tretes Office with a range of values from 25,7 gal and to the highest 26,7 gal. For the dominant period according to Kanai including type II in because the value of f0 in vulnerable value 4, which belongs to the type of surface thickness of the surface of the medium category with a thickness of 5-10meter. For Dominant Frequency get a vulnerable value at 0.2 Hz which can be said in hard character.
