Abstract

This study aims to examine the development process of a PMRI-based module supported by the GeoGebra application for teaching geometric transformations, and to determine its validity, practicality, and effectiveness for students of class XIB at SMA Negeri 10 Gowa. The research employed a Research and Development (R&D) design, following the ADDIE development model, which consists of five phases: Analysis, Design, Development, Implementation, and Evaluation. The resulting product is a PMRI-based instructional module integrated with GeoGebra for the topic of geometric transformations.The trial subjects were 21 students from class XIB. The instruments used in this study included expert validation sheets, student response questionnaires, teacher response questionnaires, learning implementation observation sheets, student activity observation sheets, and learning outcome tests. Findings from the limited-trial phase indicated that: (1) the validation scores for both the instructional materials and research instruments reached an average of 4.3, classified as highly valid, as all evaluated components fell within the interval 4 ≤ M ≤ 5; (2) the module demonstrated practicality, shown by the average student response rate of 90.4% and the teacher response rate of 90%, both categorized as positive; and (3) the module met the criteria for effectiveness, as evidenced by an average teacher performance score of 4.6 (very good), an average student activity percentage of 76% (good), and student learning outcomes achieving a mastery level of 85.8%. Based on the results of the limited trial, it can be concluded that the development of the PMRI-Based Module supported by GeoGebra for teaching geometric transformations at SMA Negeri 10 Gowa meets the established criteria for validity, practicality, and effectiveness.

Abstract

The rapid development of digital technology has driven innovation in the economic and financial sectors, including the emergence of financial technology (fintech), Bitcoin, crypto assets, and various digital financial services. While these innovations provide significant benefits in terms of efficiency, accessibility, and financial inclusion, they also raise legal issues from the perspective of Islamic jurisprudence, particularly concerning contracts (akad), riba (usury), gharar (uncertainty), and maysir (gambling). This study aims to analyze the legal status of fintech, Bitcoin, crypto assets, and contemporary riba from the perspective of Islamic economic and financial jurisprudence. The research employed a qualitative descriptive approach using a library research method. Data were collected from the Qur'an, Hadith, classical and contemporary Islamic jurisprudence literature, fatwas issued by the Indonesian National Sharia Council (DSN-MUI), relevant regulations, and reputable national and international scholarly journals. The data were analyzed using content analysis through the processes of data reduction, data presentation, interpretation, and conclusion drawing. The findings indicate that fintech is generally permissible provided it applies Sharia-compliant contracts and is free from elements of riba, gharar, maysir, and other prohibited practices. The legal status of Bitcoin and crypto assets remains a matter of contemporary ijtihād, depending on the characteristics of the assets, their intended use, and transaction mechanisms. Meanwhile, riba remains prohibited even when conducted through digital platforms because technological advancement does not alter its legal substance. Therefore, the implementation of maqāṣid al-sharī'ah serves as an essential framework for evaluating digital financial innovations to ensure justice, public benefit, and legal certainty in accordance with Islamic principles.
