Keandalan mesin sangat penting dalam menjaga kelancaran produksi, terutama pada industri make-to-order seperti PT X. Penelitian ini menganalisis efektivitas pemeliharaan mesin menggunakan Mean Time To Repair (MTTR) dan total downtime berdasarkan data kerusakan selama Februari 2022. Metode penelitian meliputi pengumpulan data kerusakan, perhitungan MTTR, dan identifikasi mesin kritis. Hasil menunjukkan terdapat 22 mesin yang mengalami gangguan, dengan downtime terbesar pada CNC Router 6.5 (1080 menit), Bending (870 menit), dan High Frequency HF1 (180 menit). Temuan ini mengindikasikan bahwa pemeliharaan masih bersifat reaktif dan menyebabkan tingginya kehilangan waktu produksi. Penelitian merekomendasikan penerapan preventive maintenance terjadwal dan peningkatan pencatatan histori kerusakan.
