Abstract

Penelitian ini bertujuan untuk menganalisis dampak komunikasi online terhadap hubungan interpersonal di era digital. Perkembangan teknologi informasi telah mengubah pola komunikasi masyarakat dari komunikasi tatap muka menjadi komunikasi berbasis digital melalui berbagai platform media sosial. Perubahan ini menimbulkan berbagai dampak, baik positif maupun negatif, terhadap kualitas hubungan interpersonal. Penelitian ini menggunakan pendekatan kuantitatif dengan metode deskriptif dan asosiatif. Populasi dalam penelitian ini adalah mahasiswa yang aktif menggunakan media sosial, dengan jumlah sampel sebanyak 100 responden. Teknik pengumpulan data dilakukan melalui penyebaran kuesioner menggunakan skala Likert. Analisis data meliputi uji validitas, reliabilitas, analisis deskriptif, serta analisis regresi linear sederhana. Hasil penelitian menunjukkan bahwa komunikasi online memiliki tingkat penggunaan yang tinggi dengan nilai rata-rata 4,1, sedangkan hubungan interpersonal berada pada kategori baik dengan nilai rata-rata 3,8. Hasil uji regresi menunjukkan bahwa komunikasi online berpengaruh positif dan signifikan terhadap hubungan interpersonal dengan nilai signifikansi 0,000 < 0,05. Hal ini menunjukkan bahwa komunikasi online dapat meningkatkan hubungan interpersonal apabila digunakan secara tepat. Namun demikian, komunikasi online juga memiliki potensi dampak negatif, seperti berkurangnya interaksi tatap muka dan kemungkinan terjadinya kesalahpahaman. Oleh karena itu, diperlukan keseimbangan antara komunikasi online dan komunikasi langsung untuk menjaga kualitas hubungan interpersonal.

Abstract

The development of artificial intelligence (AI) technology has brought significant changes to various aspects of life. However, it has also given rise to serious challenges related to data security and user privacy protection. The low level of digital literacy among the public, particularly in understanding the risks of data breaches and the misuse of personal information, has increased vulnerability to cybercrime in the digital era. This community service activity aims to enhance public knowledge, awareness, and skills in safeguarding data security and privacy amid the rapid adoption of AI-based technologies. The activity was implemented using an educational and participatory approach through workshops, interactive lectures, discussions, case simulations, and hands-on practice in securing digital accounts. The program involved 20 participants consisting of teachers and staff at SD Negeri 060922 Medan. Evaluation was conducted through pre-tests and post-tests to measure improvements in participants’ understanding. The results indicate an average increase in participants’ knowledge of 40%, along with heightened awareness of the importance of password management, privacy settings, and vigilance against cyber threats. This activity demonstrates that community-based education on data security and privacy is effective in improving digital literacy and fostering safer and more responsible technology use behaviors. Therefore, similar initiatives should be carried out on a sustained basis to support the development of a secure, ethical, and adaptive digital ecosystem in response to advancements in artificial intelligence.
