ABSTRAK / ABSTRACT
Line Laminating merupakan salah satu mesin utama pada proses produksi kaca laminasi di PT Muliaglass Float. yang berperan penting dalam menjaga kelancaran proses produksi. Tingginya frekuensi kerusakan komponen serta belum optimalnya sistem perawatan menyebabkan terjadinya downtime yang berdampak pada penurunan produktivitas, meningkatnya waktu perbaikan, dan belum tercapainya efektivitas mesin secara optimal. Oleh karena itu, penelitian ini bertujuan untuk merencanakan dan menerapkan sistem preventive maintenance sebagai upaya meningkatkan keandalan mesin serta mengurangi potensi kerusakan yang tidak terencana. Metode penelitian dilakukan melalui observasi lapangan, wawancara dengan teknisi dan operator, studi dokumentasi riwayat kerusakan, identifikasi Part kritis, serta penyusunan sistem preventive maintenance. Sistem yang dirancang meliputi jadwal preventive maintenance, checklist inspeksi, instruksi kerja dan Formulir pendukung pelaksanaan perawatan. Selanjutnya dilakukan evaluasi terhadap sistem yang disusun menggunakan Indikator Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), dan Overall Equipment Effectiveness (OEE) sebagai parameter kinerja pemeliharaan. Hasil penelitian menunjukkan bahwa penyusunan sistem preventive maintenance memberikan pedoman pelaksanaan perawatan yang lebih terstruktur dan terdokumentasi. Identifikasi Part kritis memungkinkan penentuan prioritas perawatan, sedangkan jadwal perawatan, checklist inspeksi, dan instruksi kerja membantu meningkatkan konsistensi pelaksanaan pemeliharaan. Penerapan sistem ini diharapkan mampu meningkatkan nilai Mean Time Between Failure (MTBF), menurunkan nilai Mean Time To Repair (MTTR), mengurangi downtime, serta meningkatkan nilai (OEE) sehingga keandalan dan ketersediaan (Availability) mesin Line Laminating dapat ditingkatkan.

The Laminating Line is one of the main machines in the laminated glass production process at PT Muliaglass Float. and plays a crucial role in ensuring smooth production operations. The high frequency of component failures and the lack of an optimal maintenance system have resulted in increased downtime, reduced productivity, longer repair times, and suboptimal machine effectiveness. Therefore, this study aims to design and implement a preventive maintenance system to improve machine reliability and reduce the occurrence of unplanned failures. The research was conducted through field observations, interviews with maintenance technicians and operators, documentation of machine failure history, identification of critical components, and the development of a preventive maintenance system. The proposed system consists of a preventive maintenance schedule, inspection checklists, and supporting maintenance Forms. Furthermore, the proposed system was evaluated using Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), and Overall Equipment Effectiveness (OEE) as maintenance Performance indicators. The results of the study indicate that the developed preventive maintenance system provides a more structured and well-documented maintenance guideline. The identification of critical components enables maintenance activities to be prioritized, while the maintenance schedule, inspection checklists, and work instructions improve the consistency of maintenance implementation. The implementation of the proposed system is expected to increase Mean Time Between Failure (MTBF), reduce Mean Time To Repair (MTTR), minimize downtime, and improve Overall Equipment Effectiveness (OEE), thereby enhancing the reliability and Availability of the Laminating Line machine.
