The Unitary State of the Republic of Indonesia was founded and its independence was fought for none other than to protect the entire Indonesian nation and all of Indonesia's blood, promote general welfare, educate the life of the nation, implement world order based on independence, eternal peace and social justice." This is as stated in the Preamble to the Law. -The 1945 Constitution of the Republic of Indonesia (1945 Constitution of the Republic of Indonesia) paragraph 4 (four). This means that it is the duty of the President as head of state and head of government to improve the welfare of all Indonesian people both living on the island of Java and outside Java In fact, after all these decades it turns out that there is still inequality in various fields, especially the economy between the island of Java and other regions outside Java, one of which is due to the position of the country's capital in the Jakarta area which is located on the island of Java, so that development is uneven. The high inequality in economic, social and cultural development between Java and non-Java is getting higher day by day. So President Joko Widodo, on April 29 2019, announced his policy to move the National Capital (IKN) from the DKI Jakarta area to other areas in East Kalimantan, namely North Penajam Paser Regency and Kutai Kertangerara Regency which were chosen as the potential IKN locations. President Jokowi's decision received support from the DPR RI with the issuance of Law (UU) No. 3 of 2022 concerning the Move of the National Capital. In 2023, this law has been revised or amended with the approval of the DPR RI, to become Law No. 21 of 2023. In this context, a fairly comprehensive basis and review of the study of the movement of IKN from the DKI Jakarta area to the North Penajam Paser and Kutai Kertanegara Regency areas is needed. East Kalimantan so that there is no potential for conflict to arise in IKN. For this reason, it is necessary to prepare programs and activities as well as policies to prevent or at least minimize the potential for social conflict and the impacts arising from social conflict between immigrant communities and the indigenous people of East Kalimantan. This type of research uses qualitative research methods, namely methods that focus on in-depth observation. Therefore, the use of qualitative methods in research can produce a more comprehensive study of a phenomenon. Data and information collection techniques are carried out through observation and literature study The results of the study concluded that IKN was prone to the emergence of social conflict due to the long-standing and hereditary problem of land ownership belonging to indigenous communities in North Penajam Paser. Apart from that, it is also caused by the social gap between immigrant communities, who on average have a bachelor's degree, have special skills, a high work ethic and a better level of welfare compared to the majority of native communities. Another factor is the factor of injustice between individuals in society, whether due to differences in opinions and feelings, cultural differences, politics. economic and welfare differences that can have an impact on the birth of clashes both between individuals and between community groups. It turns out that there have been many social conflicts in this area for a long time, which if allowed to continue will create disharmony between the immigrant community and the native communities of North Penajam Paser and Kutai Kertanegara.
