Abstract

This study aims to test the effectiveness of the Hypnotherapy Direct Suggestion technique in improving the emotional regulation of students who are addicted to social media. This approach was chosen because hypnotherapy allows individuals to receive positive suggestions that can help them better manage their emotions. The research method used was an experiment with the One Group Pretest-Posttest design, where the research subjects consisted of 15 students of the Faculty of Psychology, Universitas Prima Indonesia, who were selected through purposive sampling techniques. The selection of subjects was based on a high level of social media addiction, which was measured through a scale of social media use intensity. The intervention was carried out in a hypnotherapy session with the direct suggestion technique, which aims to instill positive suggestions into the subject's subconscious mind. Emotion regulation measurements were carried out before and after the intervention using the Emotion Regulation Questionnaire (ERQ) scale, which has been tested for validity and reliability. The results of data analysis using the Wilcoxon Signed-Rank Test showed a significant improvement in emotion regulation after being given therapy (p < 0.05). In addition, observations and interviews with subjects supported these findings, where participants showed positive behavioral changes, such as reduced time spent using social media and increased awareness of its negative impacts. This research provides important implications for psychological interventions in dealing with social media addiction and improving students' emotional well-being.

Abstract

Kurangnya minat anak dalam membaca Al Qur'an merupakan permasalahan yang perlu mendapat perhatian serius, mengingat pentingnya pendidikan agama sejak dini dalam pembentukan karakter dan moral anak. Etiologi dari fenomena ini sangat kompleks dan dapat dipengaruhi oleh berbagai faktor. Salah satu yang membuat menurunnya minat anak dalam membaca Al qur’an yaitu faktor lingkungan, seperti pengaruh teknologi dan hiburan modern yang lebih menarik, juga turut berkontribusi dalam menurunnya minat anak terhadap aktivitas keagamaan ini. Selain itu, metode pengajaran yang kurang menarik dan tidak sesuai dengan perkembangan usia anak dapat membuat mereka merasa kesulitan dan tidak tertarik untuk mempelajari Al Qur'an. Peran keluarga dan guru juga sangat penting dalam menciptakan suasana yang mendukung minat baca Al Qur'an, melalui pendekatan yang lebih interaktif dan menyenangkan. Oleh karena itu, perlu ada upaya bersama antara orang tua, pendidik, dan masyarakat untuk meningkatkan minat baca Al Qur'an pada anak dengan cara yang lebih kreatif dan sesuai dengan perkembangan zaman.

Abstract

Speed reading is an essential skill in facing the challenges of the 21st century, particularly in the era of the Industrial Revolution 4.0 which demands efficiency in acquiring and understanding information. This research was motivated by the low speed reading ability of fifth-grade students at SDN 02 Situjuah Gadang. Therefore, the research problem formulated in this study is how the implementation of the Problem Based Learning (PBL) model assisted by the Spreeder application can improve students’ speed reading skills. The purpose of this study is to describe the process of implementing the PBL model in speed reading instruction, analyze the improvement in students’ speed reading skills, and examine students’ responses to learning using the Spreeder application. This research is based on the theories of Dalman and Tony Buzan, who state that speed reading is a trainable skill to increase reading efficiency without sacrificing comprehension. The method used is Classroom Action Research (CAR), which was carried out in two cycles, each consisting of planning, implementation, observation, and reflection stages. The results showed that the implementation of the PBL model combined with the use of the Spreeder application significantly improved students’ reading speed. All students who initially did not meet the target of reading 100 words per minute in the first cycle were able to reach the target in the second cycle. Thus, it can be concluded that the technology assisted problem-based learning model is effective in improving the speed reading skills of elementary school students.

Abstract

Perkembangan ilmu dan teknologi komputer telah mempengaruhi segala aspek kehidupan manusia seperti di bidang pendidikan. Informasi dan data dapat dengan mudah dan cepat untuk dikirim ke konsumen melalui jaringan komputer. Hal ini tentu saja menimbulkan risiko jika informasi dan data yang dikirim bisa diakses oleh pihak yang tidak berhak sehingga mengakibatkan kebocoran data. Masalah keamanan merupakan salah satu aspek terpenting dari sebuah sistem informasi. Apabila mengganggu performansi sistem, masalah keamanan  sering tidak dipedulikan, bahkan ditiadakan. Dalam kriptografi terdapat dua konsep utama yaitu enkripsi dan dekripsi. Enkripsi adalah proses dimana informasi yang dikirim diubah menjadi bentuk yang tidak dikenali sebagai informasi awalnya dengan menggunakan algoritma tertentu. Dekripsi adalah kebalikan dari enkripsi yaitu mengubah kembali bentuk yang tersamar menjadi informasi awal. Dewasa ini telah banyak beredar  program proteksi/enkripsi data baik yang bersifat freeware, shareware, ataupun komersial. Pada umumnya, program tersebut menyediakan beragam metode kriptografi sehingga kita dapat dipilih metode yang paling aman menurut kita. Salah satu metode kriptografi adalah Kriptografi kunci publik yang dilakukan dengan cara menggabungkan secara kriptografi dua buah kunci yang saling berhubungan, yaitu pasangan kunci publik dan kunci privat. Kedua kunci tersebut dibuat pada waktu yang bersamaan dan saling terhubung secara matematis. Salah satu jenis kriptografi adalah kriptografi simetris dimana kunci yang digunakan untuk enkripsi dan dekripsi adalah sama. Jika dibandingkan dengan kriptografi kunci publik, kriptografi simetris sangat cepat sehingga sangat cocok digunakan untuk melakukan enkripsi data yang sangat besar. Banyak yang menggabungkan algoritma kunci publik dengan simetris untuk memperoleh keunggulan dari masing-masing metode kriptografi. Dalam makalah ini, penulis akan membahas lebih lanjut tentang sistem keamanan data dengan metode kunci publik.
