Abstract

ABSTRAKKegagalan isolasi masih sering terjadi pada sistem kelistrikan di Indonesia yang disebabkan oleh fenomena tegangan tinggi seperti corona discharge (CD). Hal ini dikarenakan deteksi dini kegagalan isolasi belum dapat dilakukan. Salah satu bentuk CD ialah suara. Langkah awal untuk mendeteksi dini kegagalan isolasi ialah diperlukannya suatu penelitian yang dapat mengklaster suara CD berdasarkan noise yang merupakan tujuan penelitian ini. Pengamatan dilakukan pada kubikal 20-22 kV dengan cara menaik-turunkan tegangan dengan elektroda jarum-batang sejauh 3 cm. Klasifikasi suara CD ditetapkan menjadi 3 cluster yaitu CD murni, CD disertai noise mendesis dan noise mendesis murni. Clustering dilakukan menggunakan metode linear predictive coding (LPC) sebagai ekstraksi ciri dan Euclidean distance sebagai pencocokan pola hasil ekstraksi. Adapun suhu di dalam kubikal antara 25℃ - 32℃ dan kelembaban berkisar 70% - 90%. Hasil akurasi clustering rata-rata yang diperoleh adalah 100% untuk data training dan 97,78% untuk data testing. Kata kunci: corona discharge, linear predictive coding, Euclidean distance, kegagalan isolasi ABSTRACTInsulation failures often occur in the electrical system in Indonesia caused by high voltage phenomena such as corona discharge (CD). This is because early detection of insulation failure cannot be carried out. One form of CD is sound. The first step for early detection of insulation failure is the need for a study that can cluster CD sounds based on noise which is the purpose of this study. Observations were made at 20-22 kV cubical by increasing and decreasing the voltage with a needle-rod electrode as far as 3 cm. The classification of CD sound is set into 3 clusters i.e. pure CD, CD with hissing noise, and pure hissing noise. Clustering is done using linear predictive coding (LPC) as feature extraction and Euclidean distance as pattern matching extraction results. The temperature inside the cubical is between 25℃ - 32℃ and the humidity is around 70% - 90%. The average clustering accuracy results obtained are 100% and 97.78% for training and testing data.Keywords: author’s guideline, document’s template, format, style, abstract

Abstract

The memorization and understanding of the Qur'an play a vital role in shaping a Qur'anic generation. This study aims to explore the memorization patterns in the Tahfidz and Tarjamah Qur'an programs at Darul Hufadz Islamic Senior High School. Using a qualitative research approach, data were gathered through in-depth interviews, participatory observation, and documentation from 38 informants, including the principal, five mentor teachers, and 32 students. Data analysis followed a process of reduction, presentation, and verification. The findings indicate that the Tahfidzul Qur'an program follows a daily memorization pattern known as "One Day One Verse," where students memorize one verse and its translation each day. The program emphasizes regular recitation, memorization, comprehension, and the practical application of the Qur'an’s teachings, with parental oversight. Collaborative reading sessions between teachers and students, coupled with repetition—where verses are repeated over 40 times and listened to more than 60 times—reinforce the memorization process. This structured approach effectively cultivates a Qur'anic generation, ensuring deep engagement with the Qur'an. The study highlights the importance of consistent memorization routines and active teacher involvement in fostering both cognitive and spiritual development among students.

Abstract

The LGBT (Lesbian, Gay, Bisexual, and Transgender) phenomenon among adolescents is increasingly a concern in the educational environment. It emerges in adolescents’ social lives, both as part of self-identity and as an issue that raises pros and cons in school. The lack of understanding and empathy towards this issue often gives rise to discriminatory behaviors that negatively impact the psychosocial development of adolescents. This article lifts up the good practice of implementing group tutoring in schools as a strategic approach in building students’ understanding and empathy towards LGBT issues. Through descriptive qualitative methods and a participatory approach, this article highlights how group tutoring is a safe container for discussing, exploring values, as well as fostering inclusive attitudes among students. Results indicate that the implementation of structured and empathetic group tutoring is capable of reducing prejudice as well as forming tolerant attitudes toward diversity of sexual orientation and gender identity. The purpose of this article is to look at how group tutoring functions as an educational and preventive method in building students’ understanding and empathy towards LGBT issues. To achieve this goal, a literature study has been conducted that examines various methods of group tutoring, particularly those based on humanistic and social, in building inclusive attitudes among adolescents. Study results show that group tutoring helps teens understand diversity, become more empathetic, and makes schools safe and welcoming for all students, including LGBT students. This article emphasizes the role of kindergarten teachers in designing group tutoring programs that are sensitive to diversity issues to support adolescents’ social-emotional development.
