Abstract

The development of digital technology has had a significant impact on the behavior of the younger generation, one of which is the increasing involvement in online gambling activities. This study aims to examine the impact of online gambling on social interaction and emotional stability of the younger generation. The method used is a quantitative study through data collection techniques using questionnaires, this study aims at children aged 16-26 years who are active or have been involved in online gambling. The results of the study show that involvement in online gambling causes a decrease in the quality of social interaction, such as withdrawing from the social environment, decreasing communication skills, and increasing conflict in interpersonal relationships. In addition, there were disturbances in emotional stability in the form of anxiety, excessive stress, uncontrolled anger, and symptoms of depression. Dependence on online gambling also interferes with cognitive function and decision-making, which has a negative impact on the psychological well-being of the younger generation. Therefore, preventive and curative efforts are needed from various parties, including families, educational institutions, and the government, to reduce the negative impacts of this phenomenon. Keywords: online gambling, social interaction, emotional stability, young generation

Abstract

Penelitian ini bertujuan untuk menganalisis tingkat pemahaman belajar siswa pada materi himpunan dan operasi himpunan di Sekolah Menengah Pertama (SMP), baik pada aspek pemahaman konseptual maupun prosedural. Metode penelitian yang digunakan adalah metode kuantitatif dengan teknik pengumpulan data menggunakan kuesioner berbasis skala Likert melalui Google Form. Responden dalam penelitian ini berjumlah 20 siswa SMP/SMK Cahaya Harapan Tayan, Kecamatan Tayan Hilir, Kabupaten Sanggau. Data dianalisis menggunakan perhitungan rata-rata dan disajikan dalam bentuk tabel serta diagram lingkaran. Hasil penelitian menunjukkan bahwa tingkat pemahaman siswa terhadap materi himpunan dan operasi himpunan berada pada kategori baik hingga sangat baik dengan rentang nilai rata-rata sebesar 3,80–4,20. Aspek pemahaman konseptual memperoleh hasil lebih tinggi, terutama pada indikator memahami pengertian himpunan dan membedakan himpunan kosong dengan himpunan semesta. Sementara itu, aspek pemahaman prosedural masih menunjukkan beberapa kesulitan, khususnya pada kemampuan menggambarkan diagram Venn, menyelesaikan operasi himpunan, dan menggunakan rumus banyaknya anggota gabungan himpunan. Hasil diagram lingkaran juga menunjukkan bahwa jawaban responden relatif merata pada setiap indikator. Simpulan penelitian ini menunjukkan bahwa pemahaman siswa terhadap materi himpunan dan operasi himpunan tergolong baik, namun masih diperlukan peningkatan pada aspek prosedural melalui penggunaan media pembelajaran visual, latihan soal kontekstual, dan strategi pembelajaran yang lebih interaktif agar kemampuan siswa dalam menerapkan konsep matematika dapat berkembang secara optimal.
