Abstract

Sebab distribusi tenaga listrik merupakan sistem tenaga listrik yang menyalurkan energi listrik ke konsumen, untuk menjaga pendistribusian tenaga listrik agar tidak terganggu maka sistem proteksi yang terpasang pada jaringan distribusi tenaga listrik harus bekerja secara maksimal. Koordinasi antara peralatan proteksi yang terpasang pada jaringan distribusi tenaga listrik sangat berpengaruh pada kualitas pendistribusian energi listriknya. Oleh karena itu, sistem proteksi harus memiliki tingkat selektifitas, ekonomis, kecepatan bereaksi, dan tingkat kepekaan yang tinggi sehingga sistem proteksi yang dipasang dapat dikatakan handal. Proteksi yang digunakan adalah OCR (Over Current Relay) dan GFR (Ground Fault Relay)  yaitu relai yang berfungsi memberi perintah PMT untuk membuka, sehingga saluran yang terganggu dipisahkan dari jaringan.  Penelitian ini bertujuan untuk mengetahui nilai setting relai, pengaturan waktu kerjanya, serta mendapatkan perbandingan data setting lapangan dengan data perhitungan manual antara OCR (Over Current Relay) dan GFR (Ground Fault Relay) pada sistem proteksi penyulang. Penelitian dan pengumpulan data ini dilaksanakan di ULTG Panakukkang, Gardu Induk Borongloe, UP3 Makassar, dan ULP Sungguminasa. Hasil penelitian menunjukkan bahwa penentuan nilai setting relai OCR (Over Current Relay) dan GFR (Ground Fault Relay) dilakukan dengan menghitung impedansi ekivalen jaringan penyulang untuk mendapatkan arus gangguan hubung singkat sebagai dasar penetapan waktu kerja relai (TMS). Nilai TMS yang diperoleh untuk OCR (Over Current Relay) sisi incoming adalah 0,199 detik dan sisi penyulang sebesar 0,174 detik, sedangkan untuk GFR (Ground Fault Relay) masing-masing sebesar 0,203 detik dan 0,092 detik. Koordinasi waktu kerja antara relai sisi penyulang dan sisi incoming belum sepenuhnya sesuai dengan standar grading time yang ideal (0,35–0,4 detik), karena selisih waktu yang diperoleh justru melebihi batas tersebut, yaitu 0,533 detik untuk OCR (Over Current Relay)  dan 0,582 detik untuk GFR (Ground Fault Relay). Selain itu, terdapat perbedaan antara hasil setting relai berdasarkan data lapangan dan hasil perhitungan, yang umumnya masih dalam batas wajar, kecuali pada OCR (Over Current Relay)  sisi penyulang yang menunjukkan perbedaan cukup besar akibat pengaruh nilai beban.

Abstract

The purpose of this study is to assess and analyze staff performance at PT. Banjar Industrial Borneo Facilities objectively in relation to workload, training, and personnel rotation. Given PT. Banjar Industrial Borneo Facilities' particular situation and the difficulties it faces in managing its human resources, the research site in Banjar Regency was selected. In order to provide a complete picture of the impact of research factors on employee performance, census methodologies were used to include all 48 employees of PT Sarana Borneo Industri Banjar as respondents in this study. The information utilized includes both quantitative information—obtained via government reports and personnel counts—and qualitative information—obtained from speaking with relevant authorities. Documentation and questionnaires were used in the data gathering process. The questionnaire measured respondents' attitudes, opinions, and perceptions on staff rotation, workload, and training using a Likert scale. Workload management, staff rotation, and efficient training.

Abstract

Mobile banking has become one of the most transformative innovations in the financial technology landscape, yet sustaining users' continuance intention remains a major challenge for digital banking providers. This study aims to analyze the influence of perceived enjoyment and behavioural control on users' continuance intention to use BRImo, a leading mobile banking application in Indonesia. Employing a quantitative explanatory design, data were collected from 100 BRImo users in Samarinda using a structured Likert-scale questionnaire distributed both offline and online. The instrument passed validity and reliability testing, and data were analyzed using multiple linear regression, accompanied by t-tests, F-tests, and R² evaluation. The findings indicate that both perceived enjoyment and behavioural control exert a positive and significant effect on continuance intention (β = 0.346; p = 0.002 and β = 0.404; p = 0.000, respectively). The simultaneous influence of the two variables was confirmed through the F-test (F = 76.190; p < 0.001). The model demonstrates strong explanatory power, with an R² value of 0.603, indicating that the two predictors explain 60.3% of users' continuance intention, while the remaining 39.7% may be attributed to variables such as trust, satisfaction, habit, and service quality. These results highlight the critical roles of hedonic experience and perceived behavioural control in shaping post-adoption behaviour in mobile banking services. The study extends the applicability of TAM and TPB in a post-adoption context and provides practical implications for digital banking providers to enhance user experience, emotional engagement, and perceived control to strengthen long-term usage.

Abstract

The transformation of digital learning in vocational education requires media innovations that adapt to the characteristics of digital-native students. This research aims to develop and evaluate GlideApps-based Islamic Religious Education learning media as an effective, adaptive, and accessible no-code solution. Using the ADDIE model, this research involves the stages of needs analysis, multimodal content design, application development, implementation on a limited and broad scale, and usability evaluation. Data was obtained through observations, interviews, and questionnaires from a total of 96 students. The study's results show that students need flexible, visual, and interactive media to better understand Islamic Education materials. The design process yielded an app with intuitive navigation, structured modules, interactive quizzes, and multimedia support. Expert validation shows a very high level of feasibility in both the material (89%) and media design (87%) aspects. User implementation shows that the app is easy to use and supports both self-paced and structured learning. The usability evaluation recorded an average score of 4.41 (88.13%), indicating excellent effectiveness, efficiency, and user satisfaction. The indicators of ease of understanding the material and ease of use obtained the highest score (4.53). These results confirm that GlideApps meets the principles of multimodal learning and technology acceptance theory. This study concludes that GlideApps media is efficacious in improving accessibility, engagement, and student learning experience, while offering a no-code media development model that can be replicated in the context of religious and humanities learning in vocational education environments.
