Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh pergaulan bebas terhadap ketaatan remaja dalam menjalankan kewajiban sosial dan keagamaan. Selain itu, penelitian ini juga bertujuan untuk mengetahui tingkat keterlibatan remaja dalam pergaulan bebas serta dampaknya terhadap kepatuhan mereka terhadap norma sosial dan agama. Latar belakang penelitian ini didasarkan pada fenomena berkembangnya pergaulan bebas seiring dengan kemajuan ilmu pengetahuan dan teknologi, yang sering dikaitkan dengan gaya hidup remaja masa kini. Metode yang digunakan dalam penelitian ini adalah kuantitatif dengan pendekatan survei melalui penyebaran angket secara daring. Sampel penelitian terdiri dari 28 responden yang dipilih secara acak. Data yang diperoleh dianalisis menggunakan metode statistik deskriptif untuk menggambarkan hubungan antara pergaulan bebas dan tingkat ketaatan remaja terhadap norma sosial dan agama. Hasil penelitian menunjukkan bahwa sebagian besar remaja menyadari bahwa pergaulan yang kurang baik dapat memengaruhi kepedulian mereka terhadap nilai-nilai sosial dan agama. Beberapa faktor yang berkontribusi terhadap keterlibatan remaja dalam pergaulan bebas meliputi pengaruh lingkungan, media sosial, serta kurangnya pengawasan dari orang tua. Oleh karena itu, penelitian ini menekankan pentingnya membangun kesadaran, pengawasan, dan kontrol sosial terhadap pergaulan remaja guna menjaga ketaatan mereka dalam menjalankan kewajiban sosial dan keagamaan.

Abstract

infinite series is an important concept in mathematics which often becomes a challenge for students. This study aims to analyze the difficulties faced by students of the Mathematics Department at Medan State University (UNIMED) in understanding and solving problems related to infinite series. This research uses a survey method with a questionnaire given to students who have studied this material. The research results show that the students' main difficulties lie in understanding the concept of convergence, using the convergence test, and applying it in problem solving. Based on the research results, it is recommended that there is a more interactive and technology-based learning approach to increase student understanding

Abstract

This study aims to analyze students’ mathematical critical thinking skills through the implementation of Problem Based Learning (PBL) integrated with the STEM approach on the Pythagorean Theorem material. This research employed a descriptive quantitative method involving 20 eighth-grade students of SMP Negeri 2 Lubuk Pakam in the 2025/2026 academic year. Data were collected through mathematical critical thinking tests in the form of pretest and posttest based on the indicators of interpretation, analysis, evaluation, inference, explanation, and self-regulation. Supporting data were obtained through observation and documentation during the learning process. The results showed that the implementation of Problem Based Learning (PBL) integrated with the STEM approach was able to improve students’ mathematical critical thinking skills. This was indicated by the increase in the students’ average score from 62.4 in the pretest to 90.75 in the posttest. Improvements occurred in all indicators of mathematical critical thinking skills, especially in analyzing problems, evaluating solutions, drawing conclusions, and explaining problem-solving processes systematically. PBL integrated with the STEM approach also encouraged students to be more active in solving contextual problems and connecting mathematical concepts to everyday life. Therefore, the implementation of Problem Based Learning (PBL) integrated with the STEM approach is effective in improving students’ mathematical critical thinking skills on the Pythagorean Theorem material.
