Abstract

The quality of education needs to be observed and maintained in building an effective teaching and learning environment. There are several factors that can affect the quality of education in a school, such as the availability of human resources, supportive learning facilities, environmental conditions, and various other factors. The focus of this research is on the ideal number of teachers in a school, considering the number of students and the availability of facilities such as laboratories and libraries, which will be correlated with the failure to pass the class rate. Data were obtained from the official website of the Kemdikbudristek regarding educational statistics, comprising 29 districts in Tangerang Regency for the academic year 2023/2024 at the senior high school level. The analysis was conducted using multiple linear regression, and it was found that the variables "availability of laboratory" and "availability of library" did not correlate with the failure to pass the class rate, whereas the "teacher ratio" variable correlated with the failure to pass the class rate with a value of +0.46. This can be explained that for every increase of 1 unit in the teacher ratio variable, or in other words, the fewer teachers teaching in a school compared to the number of students, the failure to pass the class rate will also increase by 0.46 students. Therefore, the results of this research can provide input for schools, especially in Tangerang Regency, to pay attention to the number of teachers in each school.

Abstract

Dalam sistem perangkat jaringan modern, idealnya sebuah perangkat jaringan memiliki manajemen sistem yang terpusat. Sistem manajemen terpusat yang baik memiliki kemampuan tidak sekedar monitoring, melainkan juga provisioning dan kegiatan administratif lain. Permasalahan yang dihadapi yakni perangkat jaringan routerboard tidak mampu melakukan provisioning secara mandiri dan otomatis. Untuk mengatasi masalah tersebut, perlu adanya sebuah sistem manajemen modern yang mampu melakukan provisioning secara otomatis, monitoring, dan juga administrasi konfigurasi secara massal. Dengan melakukan observasi dan studi literatur diketahui penggunaan routerboard dapat dimaksimalkan dengan fitur command line berupa HTTP request dan pemanfaatan arsitektur API. Penelitian ini mampu membuat sistem automasi zero touch provisioning routerboard, dengan menggunakan framework PHP Laravel dan GraphQL API. Hasil penelitian membuktikan bahwa sistem automasi mampu melakukan zero touch provisioning dengan memanfaatkan command line HTTP request untuk routerboard berkomunikasi ke server controller. Sedangkan untuk administrasi konfigurasi antara server controller ke routerboard, dilakukan melalui proses pemanggilan API. Pengujian yang dilakukan menunjukkan bahwa rata-rata durasi yang dibutuhkan dalam proses zero touch provisioning routerboard yakni 8.851ms.

Abstract

This study proposes a Hybrid Machine Unlearning framework that combines Reverse Gradient Descent (RGD) and Image Obfuscation to enable selective and privacy-preserving forgetting in deep neural networks without full retraining. The proposed method introduces a dual-layer mechanism that operates at both the model level, by reversing gradient updates to remove target class contribution, and the data level, by applying visual obfuscation to eliminate identifiable features prior to unlearning. Experiments were conducted on a subset of the Labeled Faces in the Wild (LFW) dataset containing 96 identity classes, evaluated under two unlearning scenarios with 5 and 10 target classes. Quantitative results show that pure RGD achieved values between 0.10–0.19 and 0.03–0.06 for the respective scenarios, while the hybrid RGD+Obfuscation configuration strengthened the forgetting effect up to 0.82 on MobileNetV2 and 0.26 on ResNet architectures. Model stability remained high, with below 0.27, indicating minimal degradation of non-target representations. The hybrid method achieved an unlearning time of 2–6s per epoch, with an additional 50–65% computational cost due to blurring and pixelation operations yet maintained an 80–90% reduction in total runtime compared to full retraining. These results demonstrate that the proposed hybrid approach effectively enhances forgetting strength while maintaining retention stability and computational efficiency. The method provides a scalable and resource-efficient solution for privacy-aware continual learning and AI lifecycle management, where fast and controlled machine unlearning is required without compromising model integrity.

Abstract

The concept of the mystical in society embodies an air of mystery, fear, suspense, horror, and the like, leading the inability of society to understand mystical phenomena to drive a high level of curiosity about such occurrences. Even the mystical has become a form of entertainment for society, one of which is through consuming horror content on YouTube. In the present era, Generation Z is a cohort whose lives have evolved with distinct thought patterns compared to preceding generations, parallel to the relentless development of the digital technology world. One manifestation of internet content or YouTube content is the "Langit Kelabu" expedition vlog, which explores mystical mountain climbing expeditions. The content is produced and hosted by a creator named Dzawin Nur Ikram on the YouTube channel "Dzawin Nur." This study aims to ascertain the influence and the extent of impact by the "Langit Kelabu" vlog on the Dzawin Nur YouTube channel on the attitudes of Generation Z toward the mystical. This is approached quantitatively through an explanatory survey method and utilizes purposive sampling for sample collection. The study employs the S-O-R Theory as the overarching research framework. The findings indicate a 44.3% influence of the "Langit Kelabu" YouTube vlog on the attitudes of Generation Z toward mystical phenomena. The conclusion of this study is the presence of a significant or strong correlation coefficient between the "Langit Kelabu" Expedition Vlog and the attitudes of Generation Z towards mysticism, as indicated by the coefficient of determination test results, which also show that there is a moderate level of influence from the "Langit Kelabu" YouTube vlog on the attitudes of Generation Z towards mystical phenomena.
