Abstract

Meningkatnya kasus kejahatan di masyarakat menjadi suatu yang sangat memprihatinkan. Hal ini dikarenakan salah satu penyebab kejahatan terjadi dikarenakan kurangnya pengetahuan dalam berpikir kritis yang menyebabkan masyarakat khususnya para remaja kurang menilai penting self awareness dan peduli pentingnya menjaga diri dari berbagai kejahatan. Penyuluhan ini bertujuan untuk mengenalkan kepada para remaja di desa barak gajah mengenai pentingnya menjaga diri dan menciptakan kebijakan yang inklusif dengan membangun suatu Organisasi Naposo Nauli Bulung serta menambah wawasan mencegah dan mengurangi segala bentuk kejahatan dengan melakukan kegiatan-kegiatan produktif agar menguatkan bagaimana cara mencegah kejahatan terutama istilah mutilasi tidak akan terjadi. Metode yang digunakan dalam pelaksanaan ini adalah metode Participatory Action Research (PAR) yang terbagi benjadi beberapa tahapan, yaitu pada tahapan pertama di awali dengan pemberian pre-test dalam bentuk angket untuk mengukur kemampuan awal para remaja Desa Barak Gajah terkait kejahatan, kegiatan edukasi, kegiatan nonton bersama, kegiatan pengajian, serta kegiatan olahraga. Hasil menunjukkan bahwa rata-rata pemahaman para remaja Desa Barak Gajah meningkat dari 40% menjadi 90% setelah penyuluhan. Dengan demikian, kegiatan Naposo Nauli Bulung dapat dijadikan sebagai salah satu upaya pencegah kejahatan di kalangan remaja.

Abstract

This study aims to describe students’ critical thinking skills. Critical thinking is essential for students, especially in 21st-century learning, where many students use technology to explore answers without fully understanding the questions and the solutions. This study focuses on students’ understanding of set operations in mathematics and identifies the difficulties they face. The participants were 27 ninth-grade students at Al-Manar Junior High School. The study employed a qualitative approach with a descriptive design to analyze students’ abilities to solve problems, decide and implement solution steps, perform operations, and apply mathematical induction related to set operations. The findings are expected to reveal students’ critical thinking skills and their understanding of basic mathematical concepts, particularly in set operations, as well as to identify factors influencing their understanding, thereby improving the quality of mathematics instruction at the primary and secondary education levels. The instrument used to collect data was a test administered to students on the topic of set operations. Data analysis followed these steps: data reduction, data display, and drawing conclusions. The results indicate that students’ ability to solve mathematical problems on set operations is uneven. Based on the critical thinking categories used in this study, no students reached the “very good” category; 80% were in the “good” category, 5% in the “fair” category, and 15% in the “low” category. This distribution was evident in students’ responses, suggesting that their overall problem-solving ability can still be considered good. Therefore, the researcher recommends that teachers pay greater attention to and further develop students’ critical thinking skills and their understanding of basic mathematical concepts.
