Penelitian ini berjudul Penerapan Model Pbl Untuk Meningkatkan Hasil Belajar Siswa Pada Materi Ayo Gotong Royong Melalui Media Sipatdipat Di Kelas I Sd Negeri 060912 Medan Denai. Penelitian ini merupakan Penelitian Tindakan Kelas (PTK). Penelitian ini dilaksanakan di SDN 060912 Medan Denai, khususnya di kelas 1. Adapun waktu pelaksanaan penelitian adalah pada semester genap tahun ajaran 2024/2025, yaitu mulai bulan April hingga Mei 2025 Berdasarkan hasil penelitian dan pembahasan yang telah dilakukan, dapat disimpulkan bahwa penerapan model Problem Based Learning (PBL) yang dipadukan dengan media pembelajaran SIPATDIPAT terbukti efektif dalam meningkatkan hasil belajar siswa pada materi "Ayo Gotong Royong" di kelas I SDN 060912 Medan Denai.Peningkatan hasil belajar siswa terjadi secara bertahap, dimulai dari prasiklus yang hanya mencapai ketuntasan klasikal sebesar 23,81% dengan rata-rata nilai 58, meningkat pada Siklus I menjadi 61,90% dengan rata-rata nilai 70, dan mencapai 85,71% pada Siklus II dengan rata-rata nilai 85. Hal ini menunjukkan bahwa penerapan model PBL mampu meningkatkan keaktifan, kemampuan berpikir kritis, dan pemahaman siswa, terutama ketika didukung dengan media pembelajaran yang menarik dan sesuai dengan karakteristik siswa kelas awal. Media pembelajaran permainan edukatif SIPATDIPAT sebagai media pendukung pembelajaran memberikan kontribusi besar dalam meningkatkan keterlibatan siswa dalam proses belajar, terutama dalam aspek afektif dan psikomotor. Aktivitas bermain yang dilakukan setelah diskusi kelompok dan praktik gotong royong memberikan penguatan terhadap nilai-nilai yang dipelajari dan membuat pembelajaran menjadi menyenangkan serta bermakna

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.

Digital Math Comic based on the Experience, Interaction, Communication, Reflection (MIKIR) approach is deliberately developed into a learning media needed in mathematics learning activities, especially on the material of Arithmetic Rows and Rows. So the author aims this research to find out the MIKIR-based learning approach that has existed before, the specifications of Digital Math Comic learning media, the feasibility of MIKIR-based Digital Math Comic, the advantages and disadvantages of MIKIR-based Digital Math Comic, and how MIKIR-based Digital Math Comic can increase student interest in learning. This research is a research and development (R&D) method using Thiagarajan's 4-D research model: Define, Design, Develop, and Dessiminate. The subjects of the study were students of grade VIII of SMP Muhammadiyah 1 Medan in the academic year 2023/2024 totalling 71 students. The types of data were qualitative data and quantitative data. The data were analysed qualitatively and quantitatively. The research instruments used were Digital Math Comic assessment sheets by material, language, and media expert lecturers, mathematics teachers, peers, student learning interest tests and student response questionnaires. The method of data collection through questionnaires/questionnaire sheets using a Likert scale. The results of this study indicate that the MIKIR-based Digital Math Comic is empirically proven to be valid, feasible to use, and able to increase students' interest in learning. As shown by the average score given by the validators which is 4.35 has a very good classification. Students' learning interest increased as indicated by the percentage increase in learning interest by 23% from 57% to 80%. Then the students' response to Digital Math Comic got a score of 4.2 with a good classification.

This study explores the application of the Extended Finite Element Method (XFEM) for modeling fracture behavior, utilizing COMSOL Multiphysics 5.6 to simulate a homogeneous concrete medium without embedded reinforcement. The computational model incorporates key parameters such as stress ratio (Young’s modulus of 137.9 MPa), lateral strain from axial loading (Poisson’s ratio of 0.17), concrete density of 2.4 g/cm³, and a crack growth rate governed by Paris’ law. The simulation results show a maximum stress intensity factor ( ) of 66.2 and a failure point occurring after approximately 22,568 load cycles. A mixture comprising 25% clamshell ash and lime was used as a sustainable cement substitute, achieving a maximum compressive strength of 20.53 MPa—meeting the structural concrete standard. These findings contribute to enhancing predictive fracture models and promoting sustainable material innovation in civil engineering.

Classroom Action Research aims to improve vocabulary acquisition among first-grade students using flashcards at SD Negeri 060912 Medan for the 2024/2025 academic year. Initial observations revealed that students' understanding of letters and words was not meeting developmental expectations. Only 8 out of 21 students were able to read well, while most struggled with letter recognition and word reading. To address this issue, the research employed flashcards to enhance early reading skills. The study involved 21 students (12 boys and 9 girls) as subjects. Research instruments included observation sheets, student worksheets, and pretests and posttests for cycles 1 and 2. The results showed a significant improvement in vocabulary acquisition: in cycle I, 47.61% of students had not reached the Minimum Completeness Criteria (KKM), whereas in cycle II, 85.71% of students surpassed the KKM. This indicates that using flashcards effectively improved students' vocabulary acquisition.

This Classroom Action Research aims to improve class I students' vocabulary mastery through interactive learning media (Animation) at SD Negeri 060912 Medan for the 2024/2025 academic year. Initial observations showed that students' vocabulary mastery was not in accordance with the expected development. Only 8 out of 21 students were able to recognize English vocabulary well, while most had difficulty recognizing vocabulary because it was rarely found and the memory of class 1 students was still low. Overcoming this problem, research uses interactive learning media to improve the ability to master vocabulary. There were 21 students (12 men and 9 women) as subjects. The research instruments included observation sheets, LKPD, and pretest and posttest cycles 1 and 2. The research results showed a significant increase in vocabulary mastery: in cycle I, 38.95%) of students had not reached the Criteria for Achievement of Learning Goals (KKTP), while in cycle II, 81.00% of students have exceeded the KKTP. This shows that the use of interactive learning media is effective in increasing students' vocabulary mastery.
