Email: ahyararigayo@gmail.com ABSTRACT The Aceh Government is given several special authority in managing its regions. One of the authorities is the application of Islamic values to local communities which are regulated based on Qanun. Qanun is a statutory regulation similar to a province/district/city regional regulation that regulates the administration of governance and the life of the Acehnese . This paper describes the status and position of qanun in the Indonesian legal system. The method used is normative juridical and empirical reinforcement through direct observation and using a qualitative approach. Legitimately the enforcement of qanun jinayat is legal because the application of the rules is by the derivation of the national law,. The implementation of Islamic law in Aceh is very much determined by the agencies and institutions related to the enforcement of qanun laws. However, it is known that the public does not know that there is a rule that applies and does not know that the regulation is in direct contact with their interests as citizens and members of society. This ignorance is due to the lack or absence of socialization or the introduction of the qanun during the midst of society. Keywords: aceh, qanun, islamic law, government. 1. INTRODUCTION With regard to social, cultural and economic plurality that exists today, there are number of national problems which include: First, National Integration which includes; inter-ethnic relations, inter-racial relations, the relationship between the center and the regions, the relationship between various development actors, social care among community members and so on. [1] Second, the Socio-Cultural Change which includes; changes in the basic orientation of cultural values, changes in traditional social systems, changes in the implementation of the legal system, social stratification, leadership patterns, advances in communication technology, impacts of tourism and so on. [2] Third, education which includes; gaps between ideal education and reality in various local and cultural situations, perceptions of education for different cultures, socio-political functions of schools as non-traditional institutions, disparities in educational progress between regions and so on. Fourth, Community Development which includes; changes in family income and expenditure, development constraints in certain areas, the rapid flow of globalization, the impact of technological advances, gaps in business opportunities, gaps in access to law, and so on. [3] The problems mentioned above, of course, require an integrative handler with targeted instruments. Various legal products in the form of regulations and decisions must of course be able to overcome the various existing diversity. Of course, not all legal products can fulfill or satisfy all the desires of society, especially in a pluralistic society. However, if most of the aspects of life in society have been protected and recognized by the community as a limit to behavior in society, it can be said that the relevant legal product has fulfilled the sense of justice and legal certainty of the community. [4] In the socio-cultural plurality of Indonesia, the function of law is very influential in regulating the social order. Because, basically, the law does not consider differences in ethnicity, class, position, education and so on. In addition, Indonesian National Law also comes from customary laws that apply in a region. For example, Agrarian Law comes from unwritten customary land laws. Like wise with regard to inheritance and marriage apart from customary law as well as from Islamic sharia law as currently enforced by the qanun in the Aceh region Copyright © 2021 The Authors.
