Abstract

Tujuan dari penelitian ini untuk meminimalisir dan mengetahui jadwal Preventive Maintenance mesin Heater Kernel yang efektif dan mengetahui sejauh mana Preventive Maintenance pada mesin Heater Kernel dengan metode Mean Time Between Failure (MTBF) dan Mean Time To Repair (MTTR) dapat membantu mengurangi Breakdown dan downtime. Mean Time Between Failure (MTBF) dan Mean Time to Repair (MTTR) adalah salah satu metode sebagai acuan untuk menetapkan jadwal perawatan yang efektif. Oleh karena itu perlu tindakan preventive maintenance agar dapat meningkatkan kinerja dari perusahaan, hasil analisa didapatkan nilai Mean Time Between Failure (MTBF) 18.830 menit,  yang mana hasil perhitungan ini didapat dari menghitung waktu mesin selesai diperbaiki sampai mesin mengalami kerusakan kembali dan Mean Time to Repair (MTTR) 257 menit, yang dihasilkan dari perhitungan mekanik mulai memperbaiki mesin sampai mekanik selesai memerbaiki mesin. Hasil penerapan tindakan preventive maintenance rata-rata 79,80% sehingga mesin mampu bekerja secara optimal

Abstract

Islamic Cultural History (SKI) education plays an important role in shaping students' historical understanding, Islamic values, and character. However, SKI education still faces various problems, such as monotonous teaching methods, limited learning media, low student interest and motivation, and difficulty in understanding chronological and conceptual material. With the development of technology, the use of digital platforms has become one of the innovative solutions to improve the quality of SKI learning. This study aims to examine innovations in SKI learning through the use of digital platforms and analyze the benefits and challenges in the learning process. The research method used is library research, by reviewing various sources such as books, scientific journals, and relevant literature related to SKI learning and educational technology. The results of the study show that the use of digital platforms such as audio-visual media, social media, e-learning, educational games, and artificial intelligence-based technology can increase students' interest, motivation, and understanding of SKI material. Learning becomes more interactive, contextual, and encourages active student participation. In addition, digital platforms also help teachers deliver material more effectively and efficiently. Thus, digital platform-based SKI learning innovation can be a strategic alternative in responding to the challenges of SKI learning in the digital era, while supporting the achievement of Islamic education goals oriented towards character building and digital literacy of students.
