I was involved in the development of the Department of Geology at this university from the very beginning.

★ Responsibility for coordinating the functional duties of lecturers.★ Leading the division member.

★ Lecturing the prospect of government’s civil servants, civil servants, administrators, and supervisors with at least 200 hours of lesson.★ Building up the junior lecturer.

★ Lecturing Sedimentology, Stratigraphy, and Geology of Kutai Basin in the Department of Geophysics, Faculty of Mathematics dan Natural Science with at least 30 hours of lesson. ★ Also, in the Department of Geology, Faculty of Engineering, I lecture Sedimentology with 14 hours of teaching. As a result, 44 hours of teaching this semester.

★ Lecturing the subject of Ichnology in the Department of Geology with 10 hours. A video conference served this. ★ I invited as an advisor on the subject of Ichnology the part of the Paleontology laboratory.

★ Investigation of shallow structures in East Randu Gunting East Java - Pertamina Hulu Energi - Randu Gunting. ★ Responsibility for quality control of geological data and further geological interpretation includes structural traps and depositional system.

★ Leading ichnological research team related to my Ph.D. dissertation topic. The team covers two M.Sc students who concerned on ichnology and sedimentology. ★ The result of this Ph.D. research has contributed to Indonesian ichnological research concerning depositional system reconstruction. I recognized the systems such as wave-dominated coast, delta, mixed tidal-wave coast, and estuary. Besides, a recent picture regarding the depositional system is possible.★ Six elite ichnotaxa (i.e., Ophiomorpha, Skolithos, Paleophycus, Planolites, Thalassinoides, and Chondrites) were identified. That six ones are becoming the basis for ichnofossil classification. Also, the common value of the bioturbation index (BI), ichnodiversity (ID), number of behaviors (NB), penetration depth (PD), and burrow diameter (Dm) are categorized as "low" classification.In the sedimentary records, the wave process typically characterized by the Paleophycus association. Also, the Planolites association may an indicator of the tidal processes. The dominant of Skolithos and Ophiomorpha may an indicator of the fluvial processes. ★ The mapping of ichnofabric components, lithofacies, and paleocurrent data is the basis of reconstructing paleogeography and paleoecological models. Hence, food supply and hydrodynamic energy are the key factors that regulated in the Serravallian system. It was coincident with the period of deltaic progradation. The Tortonian system was more affected by paleosalinity and paleotemperature fluctuations, which led by a relatively sea-level rise.

★ Investigation of paleotsunami deposit in Indonesia. ★ Focus on sedimentological and ichnological studies.

★ Mesozoic Geological Study of North Part Sumatera Area, Indonesia. ★ Focused on ichnofabric for paleoecological, and depositional system reconstruction.

Investigating the potential of the geological hazard, geotourism, groundwater potential, and karst revitalization.

★ Responsibility for the quality control of the provision of surface geological mapping study-Salamander Energy Bengkanai Ltd. ★ Data integration for reconstructing paleogeographic maps as the basis for further petroleum system studies.

Lecturing for prospective government's civil servants, and students with at least 5000 hours of lesson.

★ Responsibility for coordinating the functional duties of lecturers.★ Leading the division member.

Leading ichnological research team related to my Master's thesis topic. The team covers several B.Sc students who concerned on sedimentology.

★ I was one of the former lecturers in the era of the early establishment of the Department of Mines, Universitas Mulawarman. ★ Lecturing geological subjects such as Basic Geology, Petrology, Stratigraphy, Geomorphology, and Land Surveying with at least 500 hours of lesson.

★ Learning how to measure paleocurrent in the field. ★ Organize field mapping for the creation of the geological, lithofacies, bar-channel, and structural lines map with field supervised by VICO's geologist in the field. ★ Generate the outcrop's vertical sequence profiles that appended by gamma-ray curves.
