After a 10-minute break, the second session, which covered progress report on current researches under the LP, was carried out by two continuing graduate students, as summarized below.
Presenter 4: Rendy (D1)
After completing two years of LP (master’s phase), he has continued to the doctoral phase (next three years). Based on high resolution calcareous nannofossil biostratigraphic analysis, his master’s research explained the paleo-evolution of the Northeast Java basin, and also correlated stratigraphic units and sedimentary rates of three wells by using age-depth cross plots. The cross plot correlation also defined seven unconformities in the sequence and their age distribution was linked with the timing of several climatic events. Biostratigraphic analysis, seismic profiling and petrophysics showed evidence for potential petroleum stratigraphic traps related to the unconformity positions. His doctoral research will continue this work in more detail to give significant implication(s) for developing a better concept of understanding the relationship between basin history and petroleum trappings. The concept would be useful for petroleum exploration.
Presenter 5: Reza Firmansyah Hasibuan（D1）
Just like Rendy, he is continuing the second 3-year phase of his research under LP. Results from his master’s research was based on petrological and geochronological studies of the Rajabasa volcanic complex, Indonesia. His doctoral research is stemmed on an observation realized during his master’s work; the volcanoes along the arc magmatism in the Sunda strait show varying geochemical signatures ranging from alkaline to sub-alkaline series. Therefore, his current study will focus on elucidating and clarifying these features of the Sukadana basalt plateau and the Krakatau and Rajabasa volcanic complexes to explain the thermal regime and its link to tectonic evolution in the Sunda strait.
