This study aims to analyze the effect of the implementation of the Intelligent Tutoring Sistem (ITS) based on Artificial Intelligence (AI) on improving the understanding of mathematical concepts, especially in fractional and basic geometry materials, in Class V students of SD Negeri 2 Badran, Temanggung Regency. The research method used was a quasiexperimental experiment with a Non-equivalent Control Group Design. The research sample consisted of 48 students who were divided into two groups, namely the experimental group (n=24) who received learning with the help of AI-based ITS, and the control group (n=24) who received conventional learning with lecture methods and practice questions. The research instrument is in the form of a test of understanding of mathematical concepts that has been validated by experts and tested for reliability. Data were analyzed using parametric statistical tests of the Independent Sample t-test and N-Gain Score to measure the improvement. The results showed that there was a significant difference in understanding of mathematical concepts between the experimental group and the control group. The average post-test score of the experimental group (82.45) was significantly higher than that of the control group (70.12) with a p< value of 0.05. N-Gain analysis showed that the improvement in conceptual understanding in the experimental group was in the "moderate" category (g=0.56), while the control group was in the "low" category (g=0.32). These findings indicate that AI-based ITS is effective in improving students' understanding of mathematical concepts. The advantages of the system lie in its ability to provide instant feedback, personalize materials according to learning pace, and present interactive materials, thus helping to better construct students' conceptual understanding. It is recommended that schools consider the integration of ITS technology as a supplementary tool in mathematics learning at the elementary level.

The pluralistic development of Indonesian national law creates a dynamic relationship between national civil law and customary law, including in the context of resolving inheritance disputes in Chinese families who adhere to patrilineal traditions. Supreme Court Decision No. 1204 K/Pdt/2024 shows that there is a tension between legal certainty under the Civil Code and substantive justice originating from living law. This research aims to analyze the judge's interpretation of family documents as a basis for inheritance rejection, inheritance sharing mechanisms that ignore Chinese customary norms, and their implications for legal pluralism in Indonesia. The method used is normative juridical with a case study approach and a descriptive-analytical legislative approach, using literature studies of primary, secondary and tertiary legal materials. The results showed that the ruling applied neither the Civil Code nor the principle of Chinese customary inheritance consistently. The family declaration on which the judge relied was not actually a refusal of inheritance, but an internal agreement granting authority to the testator. Moreover, the distribution of inheritance carried out is not in accordance with the principle of patrilineal custom which places the eldest son as the recipient of the largest share. This finding shows the weak application of legal pluralism (weak legal pluralism) and reveals the gap between das sollen and das sein, so it is necessary to strengthen the role of judges in exploring the traditional values that live in society.

This study analyzes the legal framework and social implications of the modification licensing process in customary buildings. Modifications are often carried out in response to modernization, material changes, and contemporary functional needs, which have the potential to clash with efforts to preserve cultural values and local wisdom. Using a qualitative approach with case studies in several indigenous villages in Indonesia, data was collected through in-depth interviews, observations, and review of licensing documents and related policies. The results of the study show that there is a tension between formal licensing laws (such as Building Permits/IMB) and customary laws that apply in local communities. An effective licensing process requires intensive dialogue and collaboration between local government authorities, customary institutions, and building owners to ensure modifications still respect the values contained in cultural heritage. The study recommends a flexible and consultation-based licensing framework that harmoniously integrates positive legal aspects and customary norms, while promoting community awareness and participation in heritage conservation.
