Kemampuan manajerial kepala sekolah mencakup berbagai aspek, termasuk perencanaan strategis, pengelolaan sumber daya, kepemimpinan, komunikasi, dan penilaian kinerja. Kepala sekolah yang memiliki kemampuan manajerial yang kuat cenderung dapat mengelola sekolah dengan lebih efisien, merancang program pembelajaran yang efektif, dan mengelola konflik dengan baik. Hasil uji Pengaruh Kemampuan Menejerial Kepala Sekolah, Kemampuan Profesional Guru dan Komitmen Kerja Guru Secara Simultan Terhadap Kinerja Guru Diketahui F hitung = 5748,038 dan F tabel = 2,790, maka F hitung > F tabel sehingga secara simultan berpengaruh dan nilai sig < 0,05 maka dinyatakan signifikan. Sementara uji T parsial pertama diketahui nilai koefisien kemampuan manajerial kepala sekolah yaitu 0,738 (positif) hal ini menandakan pengaruh kemampuan manajerial kepala sekolah berpengaruh positif terhadap komitmen kerja guru. Kedua koefisien kemampuan Profesional Guru (X2) yaitu 0,261 (positif) hal ini menandakan pengaruh kemampuan Profesional Guru berpengaruh positif terhadap komitmen kerja guru. ketiga, nilai koefisien kemampuan manajerial kepala sekolah yaitu 0,753 (positif) hal ini menandakan pengaruh kemampuan manajerial kepala sekolah berpengaruh positif terhadap kinerja guru. Keempat, pengaruh kemampuan Profesional Guru berpengaruh positif terhadap kinerja guru. Sementara signifikan (sig) variabel Kemampuan Profesional Guru (X2) terhadap Kinerja Guru (Y) adalah sebesar 0,162 .Karena nilai sig 0,162 > probabilitas 0,05, maka hipotesis ditolak. Kelima, kemampuan Profesional Guru berpengaruh positif terhadap kinerja guru. Sementara signifikan (sig) variabel Kemampuan Profesional Guru (X2) terhadap Kinerja Guru (Y) adalah sebesar 0,162 .Karena nilai sig 0,162 > probabilitas 0,05, maka hipotesis ditolak

This research aims to develop an augmented reality-based teaching material, namely the AR-Geo module on 3D Geometry material at SMA Negeri 3 Medan. These teaching materials are able to determine the level of validity, practicality, and effectiveness of the AR-Geo module and student responses to learning. This research method used research and development (RD) through the ADDIE model. The subjects of the study involved students of class XII IPS 1 SMAN 3 Medan in the academic year 2023/2024 totaling 36 students. The research instruments employed AR-Geo module assessment sheets by media and material expert lecturers, mathematics teachers, peers, student ability tests and student response questionnaires, as well as student spatial ability tests. The results indicate that the material expert score is 91,53% and the design expert score is 90,53%, classified as very valid. The practicality of the module can be identified from the teacher response questionnaire score of 80,00% classified as practical, and the questionnaire score in the small group trial of 84,26%, field test 84,38% classified as very practical. The effectiveness is shown by 83,33% of students completing the learning outcomes test, and the results of the N-Gain calculation are 17 students experiencing an increase in medium spatial ability and 19 students experiencing an increase in high spatial ability. As a result, the development of augmented reality-based modules for 3D geometry material that has been developed is feasible to use.

There has been a lot of research on ethnomathematics regarding ombusombus cake, but no one has studied their mathematical value from all aspects of the material other than 2D shapes or 3D shapes. This research aims o look for mathematical activities in North Tapanuli culture and focused on developing the ethnomathematics value of the traditional ombusombus food cake typical of North Tapanuli as a source of mathematics learning. The basic ingredient for making ombus-ombus is rice flour. This research is descriptive qualitative research with an ethnographic approach. Data collection techniques were carried out using observation, documentation, and literature review. Data analysis techniques using Spradley design: domain analysis, taxonomy, compatibility, and cultural themes. Based on the results of data collection, there were several mathematical elements in the traditional ombus-ombus cake typical of North Tapanuli. The mathematical elements contained include the concept of comparison, flat shapes (triangles and squares), space shapes (quadrangular pyramids), social arithmetic concepts, measurement concepts, and counting concepts. In this way, Ombus-ombus can be used as a medium for teaching mathematics in the classroom.

Students have difficulty learning algebra, so they need help to solve it. The biggest challenge students usually face in learning algebra is understanding the concept of variables, equations, and symbolic manipulation. This study aims to analyze the effectiveness of the practice and practice method with a game approach through the Cymath application in learning algebra in junior high schools. This study used a pretest-posttest experimental design with a control group. The sample consisted of 50 students divided into an experimental group of 30 who used the Cymath application and a control group of 20 who did not use the application. The data collection method used a test. The data collection instrument used a test question sheet. Data analysis testing was carried out using the SPSS software version.27 using Kolmogorov-Smirnov and Shapiro-Wilk test statistics for normality, homogeneity, and independent sample T-test tests. The data analysis results showed a significant difference between the experimental group and the control group in terms of improving understanding of algebraic concepts. The experimental group had a standard deviation, which indicated that the scores of students in this group were more centered around the average value. It is concluded that the training and practice method with a game approach through the Cymath application can improve learning outcomes in algebra material.

This study investigates the influence of World Development Indicators (WDI) on the Human Development Index (HDI) within the regional context of Asian countries. Understanding the interaction between these indicators and HDI holds strategic relevance for enhancing the formulation of evidence-based development policies. The analysis focuses on five key indicators: population growth, voice and accountability, government effectiveness, GDP per capita growth, and control of corruption. These variables represent essential dimensions of governance and socioeconomic advancement. The dataset comprises information from 46 Asian countries sourced from the World Bank. The methodological framework integrates multiple linear regression to evaluate the magnitude of each variable’s contribution to HDI. The Preference Selection Index (PSI) is utilized to establish a performance-based ranking of countries grounded in the selected indicators. Results demonstrate that population growth and government effectiveness have significant impacts on HDI outcomes, while the remaining variables exhibit no statistically significant effects. Comparative analysis using PSI reveals inconsistencies between development indicator values and actual HDI positions. South Korea shows the highest consistency between quantitative rankings and HDI classification. These findings offer practical insights for policy prioritization by identifying the most influential determinants of human development in the region. The study emphasizes the importance of tailored development strategies and encourages future research to strengthen model robustness through control variable inclusion, sensitivity analysis, and non-linear modeling approaches.
