Book excerpt: This is an open access book.Changes in law either from the meaning of normative substance, institutional, and legal culture are inevitably in line with the dynamics within various sectors of life society. Therefore, it is necessary to thoroughly discuss and analyze which sectors may have a significant impact on the business world and society today. By discussing comprehensively, comparatively and collaboratively, it is hoped that legal issues can be seen from various perspectives in the legal and social fields by finding fundamental problems in depth related to several topics of discussion, including in the telematics legal sector, natural resource management law, business legal culture, as well as the tourism sector. For this reason, APPTHI held a series of conferences in 3 cities to discuss and make it a meeting place for world law experts with law lecturers throughout Indonesia and invited lecturers from various countries, such as South Korea, India, Malaysia and Europe to take a part in this conference. The 1st APPTHI International Conference on Changing of Law (the series) is the first international conference series held in Indonesia by the Association of Indonesian Law College Leaders (APPTHI), inviting several legal experts from countries such as the USA, the Netherlands, Korea, Malaysia, India, as well as South Korea.
