This study aims to analyze the implementation of women's inheritance rights within the patrilineal customary system of Karo ethnic group and the judicial considerations based on the Medan High Court Decision No. 400/Pdt.2023/PT MDN. The urgency of this research lies in harmonizing legal pluralism, particularly the role of judges in inheritance cases and their impact on the development of customary law and gender equality for Karo women and the community. This study employs a normative juridical method to examine the application of customary inheritance law in the distribution of inheritance assets through judicial decisions. The novelty of this research expands on an analysis of the implementation of Karo customary inheritance law in relation to gender equality within civil inheritance law. It refers to the inheritance rights of Karo women in actual cases, distinguishing it from other studies that discuss Karo customary inheritance law or court case resolutions in a purely regulatory manner. The findings reveal that the implementation of Karo women's inheritance rights is reflected in court decisions, where women receive a share, albeit smaller than men, due to differences in rights and obligations. Judges consider customary law as the closest legal framework for the family while also taking gender justice into account by accommodating the inheritance rights of Karo women. The application of Karo customary inheritance law in asset distribution continues to uphold gender fairness for Karo women. This study is expected to contribute both practically and theoretically to the enforcement of a just customary inheritance law.

The number of MSMEs that have halal certificates is still far less than large industries, including MSMEs in Kedungsalam Village, Donomulyo District, Malang Regency. Based on these problems, the Accounting Department of Universitas Negeri Malang (UM) held a halal literacy activity for MSMEs. This halal literacy activity has never been obtained by participants before. The purpose of this activity is that in the future MSMEs in Kedungsalam Village can improve product quality through halal certification, so that they can survive and compete in the globalization era. This service activity is considered right on target, because MSME products that are not yet halal certified can register through the Halal Center at UM. The UM Halal Center has been officially established since early 2019 which has a role in providing services to the community's needs for halal certification, namely accompanying, fostering, and overseeing halal product guarantees.
