PREFACEThe role of computation and simulation to support research activities in sciences and technologies has become more important in recent decades. The International Conference on Computation in Science and Engineering (ICCSE) 2017 has been conducted in Bandung Institute of Technology (ITB) campus, Bandung, Indonesia, on 10-12 July 2017. This conference is organized by Bandung Institute of Technology (ITB, Indonesia) and supported by UIN Sunan Gunung Jati University. This conference aims at summarizing recent research activities relevant to the computation application in science and engineering and facilitate communication among relevant experts.More than 150 people from Indonesia, Japan, Malaysia, India, Australia, Korea, and some other countries have participated in this conference. About 150 presentations including 9 plenary talks are presented. The presentations are grouped into 12 areas of particular interest: (1): Complex system Modelling, (2): Energy System Computation, (3): Fluid Dynamics Computation, (4): Artificial Intelligent and Soft Computing, (5): High Energy Physics, (6): Simulation in general, (7): Quantum Computation, (8) HPC, (9): Material Computation, (10): Sub surface modelling and computation, (11): Nuclear and Radiation Computation, and (12): Atmospheric and meteorological computation.From about 100 full papers submitted after the conference for publication in IOP conference proceedings, after peer review process by relevant experts, 83 papers were accepted for publication in this proceeding. We are indebted to all of authors for submitting their original papers.We would like to thank all participants, all members of the International Board, members of the Organizing Committee, and I express my gratitude to all those who helped the success of this conference.Zaki Su’udDwi IrwantoICCSE 2017 ChairmanICCSE 2017 Co-Chairman
