The 2nd International Conference on Tropical and Coastal Region Eco Development (ICTCRED) 2016 was held by Research and Community Services Institute, Diponegoro University, Indonesia in Bali during 25-27 October 2016. Bali, the god island amid pleasant surroundings, was a delightful place for this conference. The 165 research papers were presented both by oral and poster presentation, and the conference had delivered many fruitful discussions and exchanges that contributed to the success of the conference. Among these papers, we selected 72 papers through intensive review by scientific committee. Participants from 10 countries made the conference truly international in scope and the presentations were split into two main conference areas, i.e., tropical life sciences and Coastal Region Developments. There were 7 plenary lectures covering the different areas of the conference: Prof. Ocky Karna Radjasa (Ministry of Research, Technology and Higher Education) talked on Policy on Coastal Research in Indonesia, Prof. Ambariyanto (Diponegoro University) on Update in Coastal Development, Prof. Makoto Tsuchiya (University of the Ryukyus – Japan) on Coral Reef Ecosystem, Prof. Peter Gell (Federation University of Australia – Australia) on Pollution and Coastal Environmental Changes in Tropical Region, Prof. Johan C. Winterwerp (TU Delft, Netherlands) on Restoring eroding mangrove-mud coasts through Building with Nature. These plenary speakers have given significant scientific contributions to the conference.Participants have delivered their talks of valuable research outputs which are varies from extracting valuable compounds from marine environment and convert them to specialty products. During the presentation, marine products and their processing were also elaborated with developments in oceanography technology, coastal environment management and policies. These topics were more fruitful when researches in social science and its developments especially at the coastal area were also presented. These wide range of topics have colorized this conference.Finally, it is appropriate that we record our thanks to our fellow members of the Organizing Committee and of the Scientific Committee for their work in maintaining high quality of papers and in encouraging participation from those areas. We are also indebted to those who served as chairman of Institute of Research and Community Services, Diponegoro University and Ministry of Research, Technology and Higher Education for their financial supports. Without their support, the conference could not have been the success that it was. We also acknowledge the authors themselves, without whose expert input there would have been no conference. The continuing success of this conference series means that planning can now proceed with confidence for the same event in 2017.Guest EditorsHadiyanto,Chair of Scientific CommitteeScientific Committee/EditorHadiyanto (Diponegoro University, Indonesia)Makoto Tsuchiya (University of the Ryukyus, Japan)Heru Susanto (Diponegoro University, Indonesia)Muhammad Mukhlisin (Semarang State Polytechnic, Indonesia)Jamari (Diponegoro University, Indonesia)Hussein Gasem (Diponegoro University, Indonesia)Ambariyanto (Diponegoro University, Indonesia)Muhammad Zainuri (Diponegoro University, Indonesia)Muhammad Ali (Mataram University)Sultana MH Faraz (Diponegoro University, Indonesia)Gerard Pals (Vrije Universiteit Amsterdam, Netherland)Randi Hagerman (University of California Davis, United States)Flora Tassone (University of California Davis, United States)Herawati Sudoyo (Eijkman Institute, Indonesia)Ocky Karna Rajasa (MRTHE, Indonesia)Craig Starger (Colorado State University, United States)CN Ravishankar (Central Institute of Fisheries Technology, India)Agus Sabdono (Diponegoro University, Indonesia)Maria Barbosa (Wageningen University, Netherland)Yasuhiro Igarashi (Japan)Irwandi Jaswir (IIUM, Malaysia)Michio Hidaka (University of the Ryukyus, Japan)Organizing CommitteeMunawar A RiyadiChairTri Indah WinarniCo-Chair of TLSDiah Permata WijayantiCo-Chair of CREDEko SusantoSecretaryDesrinaProceedingMuh.
