This is an open access book. The universe and society, both macro and micro, were created based on the laws of order which in principle have something in common. For example, the Milky Way solar system in which the center of the solar system is the sun, is surrounded by planets in its orbit. These planets, like Earth, are surrounded by their moons. It turns out that even very small objects such as atomic molecules have a circular model. The aims of research is to find these regularities to facilitate and improve the quality of life.The advancement of science and technology, sport, languages and arts are dedicated not only to facilitate the human life but also educate human being themselves. Arts is the highest achievement that contain values of life that highly respected by a nation. It can be said that arts are reflection of the civilization including moral, and vise versa; civilization as the representation of the advancement of moral, science, technology, cultures, languages, and arts by human being.The viruses that cause the Covid 19 pandemic are hard to anticipate. Everything must be changed. This means that it is necessary to strive for innovative methods to STRENGTHEN EDUCATIONAL RESEARCH AND INNOVATION BASED ON MORAL, SCIENCES, AND ART IN NEW ERAICERI is an international conference that accomodates research and innovation in educational practices in various fields of study. For this reason, ICERI is held in conjunction with other international conferences that fall under the scope of educational practices. This includes INTERCOME which is a conference in music education, ICoPCoSE which is a conference on teacher education (the teaching practicum, industrial practicum, and students community service in education).
