Abstract

This research has proved the occurrence of pre-Tertiary palynomorphs within the Buya Formation of the Sula Island. Most palynomorphs have Australian affi nity and appear in most Mesozoic basins in Australia and in Papuan Basin of Papua New Guinea. The palynomorph assemblage mostly consists of spores as well as dinofl agellates. Three micro-fl ora zones can be defi ned referring to the existing index spores, including (from older to younger zone) Contignisporites cooksoniae zone, Murospora fl orida zone and Retitriletes watheroensis zone. Meanwhile, four dinofl agellate zones enable to be constructed such as (from older to younger zone) Caddasphaera halosa zone, Wanaea clathrata-Wanaea indotata zone, Dingodinium swanense zone and Criboperidinium perforans zone-younger zone. Both zonations suggest that the age of the Buya Formation is Middle to Late Jurrasic or Bathonian to Tithonian. From the palaeobiogeographic point of view, the similarity between palynomorphs from the Buya Formation of the Sula Island and those from the Mesozoic sediment of Australia suggests land connection between both areas during Middle to Late Jurassic. It suggests that, during this age, the study area attached the Australian Continent which was situated far South from the equatorial. The study area appears in its recent position during Neogene.

Abstract

This study aimed to analyze the effect of the TGT (Teams Games Tournament) learning model assisted by Wordwall on student activity and cognitive learning outcomes in the digestive system material. The research employed a one-shot case study design, with the subjects being students of classes XI.1 and XI.2 at SMA Negeri 1 Bukateja, selected through purposive sampling. The independent variable in this study was the TGT learning model assisted by Wordwall, while the dependent variables were student activity and cognitive learning outcomes. The research results showed that student activity indikators, including visual, oral, listening, motoric, and mental aspects, achieved an average activity percentage of 87.5% by the fourth meeting, categorized as excellent. Cognitive learning outcomes also demonstrated a significant improvement, with an average N-gain score of 0.81 (high category). The highest improvement was observed in the understanding indikator (C2), which increased by 34%. The findings revealed that the TGT learning model assisted by Wordwall positively impacted both dependent variables. This study concludes that the TGT learning model assisted by Wordwall is effective in enhancing student activity and cognitive learning outcomes.
