Abstract

The biannual International Conference on Mathematics and Natural Sciences (ICMNS) is a series of inter-disciplinary conference specially organized to celebrate the birthday of the Faculty of Mathematics and Natural Sciences, Institut Teknologi Bandung, officially founded on the 6th of October 1947. In 2018, it was the 7th ICMNS that was held at the campus of Institut Teknologi Bandung, on November 2-3, 2018. The particular character of this conference is still maintained, i.e., to promote multi-and inter-disciplinary researches in sciences and their applications. So it should cover ‘broad-but-related’ topics in science. Besides to disseminate recent research results in the field of sciences and mathematics, the 7th ICMNS also called special theme, i.e., to encourage the development of sciences and technologies for food, health, and sustainable energy.In order to create strong interactions of multi-disciplinary areas, we distribute the topics in 11 different areas covering Chemistry, Physics, Mathematics, Material Science, Computational Science, Medical and Pharmaceutical Sciences, Life Sciences, Environmental Sciences, Science of Renewable Energy, Earth and Space Science. As we learned from previous experiences, this should also allow people from faculty of engineering could participate in this conference and make collaboration with those from other related fields.For the 7th ICMNS, we are mostly honored to have several distinguished invited speakers for selected fields. Therefore, we are indebted to Professor Hans Z. Munthe-Kaas (University of Bergen, Norway), Chair of CIMPA Scientific Council and Chair of Abel Prize Committee and Professor Juan Bisquert (Universitat Jaume I, Spain), Director of Institute of Advanced Materials, as keynote speakers, and several distinguished scientists as plenary speakers, that is, Dr. Ilya Shadrivov (Australian National University College of Science, Australia), Dr. Hadi Susanto (University of Essex, UK), Dr. Avan Suinesiaputra (The University of Auckland, New Zealand), Prof. Matthew Colless (Australian National University, College of Science, Australia), Veinardi Suendo, Ph.D. (Institut Teknologi Bandung, Indonesia), for their special contribution. They have presented recent development in their respected fields to inspire many young scientists, in particular, and all participants in this conference. Accordingly, it is expected to generate cooperation among them.To facilitate active interaction, like previous event in this series, we also organized mini-symposia, to gather more people in the fields sharing their ideas. The mini-symposia focused themes on: (1) Coastal and Ocean Dynamics, discussing issue related to oceanographic operational system, forecasting and prediction with data assimilation, and numerical modeling result related to coastal and ocean dynamics; (2) Building Indonesian Observatories Network, regarding that some new observatories with permanent telescope building (dome) have been constructed, then it is about the right time for these enthusiasts to share their experience and plan for the future, in this mini-symposium; (3) Various Aspects in Combinatorics, aiming to introduce recent progress of various aspects in Combinatorics to broad audiences, in particular to combinatorialists; (4) Optics, Photonics and Their Applications, intended as forum of scientific communications and interactions among scientists working in optics and photonics science covering a broad spectrum from theory and modeling to biomedical applications; (5) Nonlinear Phenomena, dealing with the dynamics and bifurcations in a system; (6) Science and Technology of Solar Energy Conversion, intended to facilitate a forum for the researchers in this field to share their results and new research ideas.We noted that there were 355 registered participants and about half of them are graduate students. The organizer has reviewed 310 abstract accepted as contributed papers, either in oral or poster presentations. For the written versions, after being reviewed and revised, we also regrouped the accepted papers into several categories, and in this edition of physical sciences, we have accepted 94 papers to publish.Last, but certainly not least, we are extremely grateful to all participants who made the collaborative spirits always high and enjoyable, and we apologize for all shortcomings in the organizations of the conference. The organizing committee appreciates very much all the helps from the SOC as well as the hard work of the LOC.April 2019Editors/Organizers
