Abstract

Geometry, which is a branch of mathematics related to visualization often makes students less motivated. Thus, the ability to think mathematically, which is suitable with Van Hiele's geometric thinking ability, need to be promoted in any interactive mathematics learning. Thus, this research is aimed at examining how students' high order thinking skills through the application of Van Hiele's theory with the help of animated videos.  Van Hiele's geometric thinking stages consist of visualization, analysis, abstraction, deduction, and rigor. To apply it, researchers used the Thiagarajan learning model known as the Four-D Model. Participants involved in this study were eleventh grade students of an Islamic secondary school in Sumatra, Indonesia. The instruments used were learning tests and student worksheets. Results indicates that Van Hiele's theory aided by video animation helps students improve students thinking skills and students experience regarding their ability to solve geometric higher-order thinking skill problems.Keywords: HOTS, Van Hiele, Geometry, Video Animation

As technology advances, digital payment solutions have emerged as a practical way to streamline transactions and boost MSMEs' operational effectiveness. Data from MSME actors in the area is gathered for this study using a quantitative methodology and survey method. According to the study's findings, MSME productivity is positively impacted by the use of digital payment systems like e-wallets and QRIS. Companies report faster transactions, lower operating expenses, and easier access to larger markets. In addition, digital payment methods contribute to more transparent and accurate financial records. The study's conclusions include the necessity of educating and training MSME participants on the usage of digital payment systems, as well as government and financial institution assistance to promote the technology's uptake.
