Abstract

Penelitian tentang pergeseran tanah (ground shear strain) di Kota Palu menggunakan data mikrotremor telah berhasil dilakukan.  Penelitian ini bertujuan untuk menentukan nilai dan keadaan pergeseran tanah di Kota Palu. Daerah penelitian ini meliputi 3 kecamatan yaitu Kecamatan Mantikulore, Kecamatan Palu Barat, dan Kecamatan Palu Timur. Tahapan penelitian menggunakan data sekunder mikrotremor berupa frekuensi dominan (f0) dan faktor amplifikasi (A0). Indeks kerentanan seismik (Kg) dan nilai percepatan getaran tanah maksimum Peak Ground Acceleration (PGA) diperoleh dengan menggunakan nilai f0 dan A0 tersebut.  Hasil analisis f0, A0, perhitungan Kg dan PGA maka didapatkan nilai pergeseran tanah (?). Hasil penelitian ini menunjukkan bahwa besar nilai pergeseran tanah (?) di Kota Palu berkisar antara 4,66 x 10-6 sampai 1,00 x 10-4. Keadaan tersebut, akan menyebabkan sebagian besar Kota Palu mengalami keretakan atau pergeseran jika terjadi gempabumi dan sebagian kecil hanya mengalami getaran tanah

Abstract

 AbstractThe purposes of this study were to determine differences of activities and learning outcomes between students were taught using Think Pair Share (TPS) Cooperative learning model and conventional method and effect of applying Think Pair Sharecooperative learning model toward learning outcomeson redox materials at X Grade of IPA SMAN 1 Sungai Raya. Quasi-experimental with nonequivalent control group design was used as research method. The samples were students X IPA 4 as control class and X IPA 2 as experimental class that were determined with random sampling technique. Activities and outcomes learning were analyzed using U-Mann Whitney. The result of data analysis showed that differences activities and learning outcomes beetwen students were taught using cooperatif learning model Think Pair Share type and conventional method. Think Pair Share cooperative learning model give effect with value of 33,89 % on increasing students learning outcomes.  Keyword: Think Pair Share, activities, learning outcomes, redox
