Preface: Proceedings of the International Symposium on Frontier of Applied Physics (ISFAP) 2016The International Symposium of Frontier of Applied Physics (ISFAP) 2016 was a scientific meeting that is technically organized by Research Center for Physics in conjunction with Indonesian Science Technology Festival organized by Deputy of Engineering Sciences, Indonesian Institute of Sciences (LIPI). ISFAP was held on 3 - 5 October, 2016 at Indonesia Convention Exhibition (ICE), Serpong, Indonesia. The event was supported by Indonesian Physical Society (HFI), Indonesian Institute of Sciences (LIPI), and Indonesian Society for Microscopy (Ina-SM).This symposium aimed to bring together researchers, academicians, and scholars all around the world to share information and their research results. This event was also expected to become a beneficial media in exchanging their innovative ideas and build research collaborations in the future. The symposium covered all scientific and technical activities in physics – from basic to the advanced applications – especially those related to advanced material sciences for energy, nanotechnology, geophysics, lasers and optoelectronics, magnetism and superconductivity, hybrid, ceramics, and composite materials, material process engineering, surface and corrosion science.We specially invited 4 scientists as keynote speakers, 4 researchers as invited speakers, and 4 researchers as selected speakers from various countries to share their knowledge to all participants. The total participants attending this symposium were 133 persons. This symposium has successfully attracted 109 submitted papers. Papers that have been presented in the ISFAP 2016 were eligible for publishing in IOP Journal of Physics: Conference Series. The editorial board has decided to accept 75 papers from Indonesia, Philippines, Nigeria, South Africa, Saudi Arabia, Egypt, Malaysia, Germany, and Taiwan. The accepted papers have passed through strict reviewing process by scientific committee of this symposium. EDAS system has been used to facilitate the submission, reviewing, and revision processes.We would like to appreciate all of our co-organizers, supporting societies, sponsors, and Research Center for Physics staffs who have contributed generous amount of grants and effort to support us during the symposium. We hope this symposium has successfully enabled us to share and communicate our knowledge and skills and to build collaborations among the participants. We are looking forward to welcoming you in Indonesia again. See you in ISFAP 2017!
