Joko Samiaji, Ir, M.Sc., Ph.D. is a senior lecturer at the Marine Science Department, University of Riau (UNRI), Pekanbaru, Indonesia. He was born on 30th September 1965 in Boyolali, Central Java. He finished his education as follow: B.Sc. with Honours (Ir.) in Fishery from Universitas Hasanuddin, Makassar, Indonesia in 1988; M.Sc in Marine Biology from Mount Allison University, Sackville, New Brunswick, Canada in 1994; Ph.D. in Oceanography from School of Ocean and Earth Science, University of Southampton, United Kingdom in 2001. In 2002-2003 he joined the Postdoctoral Program in Marine Ecology at the Centre for Tropical Marine Ecology(ZMT)- University of Bremen, Germany. From 2005-2013 he was actively involved in the SPICE (Science for the Protection of Indonesian Coastal Ecosystems) Project as the Indonesian Sumatran Cluster Coordinator. His latest research and community service project was on the conservation of peat-swamp and coastal ecosystem in 2017-2018 under the scheme of Indonesian Climate Change (ICCTF) and funded by the UK-Climate Change Fund (UKCCF). He also actively participates in higher education capacity building with the functions as: Head of UNRI’s Accreditation Center in 2004-now, reviewer for National Education Council in 2006-now, national assessor for accreditation in 2008-now, ASEAN University Network for Quality Assurance (AUN-QA) assessor in 2012-2013, Executive Director for UNRI’s I-MHERE (Indonesia-Managing for Higher Education for Relevance and Efficiency) Project in 2008-2013, Manager of UNRI’s ADB-AKSI (Asian Development Bank-Advance Knowledge Science for Indonesian Higher Education) Project in 2016-2018. Participation in UNISTAFF (University Staff) 2009 and UNITRACE (University Tracer Study) 2011+2012 trainings by DAAD-Germany and conducted in University of Kassel, has given him more perspectives in developing his career on higher education based on German universities experiences. Since 2018 he has served as the director of Matauli College for Fisheries and Marine Science in Tapanuli Tengah, North Sumatra Province.
