Abstract

The Nambo Formation distributed in the eastern of Sulawesi is well exposed along the Nambo River, Luwuk, Central Sulawesi. In this locality it consists of calcareous grey shale, with some calcareous sandstone interbeds,  about 50 m thick. The molluscan fauna is composed among others of Retroceramus (R.) haasti, Malayomaorica malayomaorica, B. aucklandica similis, Belemnopsis moluccana, B. galoi, B. stolleyi and B. mangolensis. It is concluded that based on the molluscan faunal assemblage, the age of the formation is Tithonian. It is correlable with the upper part of the Buya Formation in the Sula Islands. Keywords : Nambo Formation, molluscs, Tithonian, Nambo River, Central Sulawesi, Buya Formation, Retroceramus, Malayomaorica,  Belemnopsis.

Abstract

Paleoecological analysis and depositional history of the marine Jurassic to Early Cretaceous, Toarcian - Early Berriasian, strata cropped out at the southeast coast and the islets of Misool are discussed. The macrofossil fauna subdivides the stratigraphy of the areas into 4 assemblages. In stratigraphic ascending order these are 1. Bivalve - Ammonite Assemblage with a Bositra ornate, 2. Belemnite – Bivalve Assemblage 3. Ammonite – Bivalve - Belemnite Assemblage and 4. Bivalve - Ammonite- Belemnite Assemblage.Bivalves occur in the whole section of Toarcian - Berriasian, while belemnite made its first appearance in the Early Callovian time and continued to the Cretaceous. The Ammonite plays an important role and is presented only in Assemblages 1, 3 and 4.The paleoenvirontmental deposition of the Jurassic to Early Cretaceous of the Misool Archipelago was likely related to a continental shelf and continental slope of low energy. The presence of a Bositra ornati Sub-assemblage indicates a restricted basinal anoxic condition for a short period in the Aalenian Stage. PaleogeographIcally, the Misool Archipelago in the Jurassic time was likely located at the northern margin of the Gondwana land or at the southern coast of the Tethyan Sea.Keywords : Jurassic, Early Cretaceous, Toarcian, Early Barriasian, Misool

Hasil pre-test menunjukkan rata-rata subjek penelitian 85,5 memiliki tingkat kecerdasan emosional yang Low Average (dibawah rata-rata), dan hasil posttest menunjukkan rata-rata subjek penelitian 110 memiliki tingkat kecerdasan emosional yang Average ( rata-rata).Hasil analisis uji t untuk menguji perbedaan rata-rata data pretest dan posttest dk = 6, α = 0,05 di peroleh t (hitung) = 11, 9598 > t (table)= 1, 94318, disimpulkan ada perbedaan secara signifikan rata-rata skor pretes dengan Rata-rata skor postes. Hasil penelitian ini menunjukkan bahwa terdapat perbedaan yang signifikan antara tingkat kecerdasan emosional siswa sebelum dan sesudah diberikan teknik assertive training. Kesimpulan meningkatnya tingkat kecerdasan emosional siswa kelas 2 SMA Tarkeeyahtul Ummah school Thailand dari kategori Law Average menjadi kategori Average melalui kegiatan layanan teknik assertive.
