PT Tirta Investama Cianjur merupakan perusahaan yang bergerak di bidang produksi Air Minum Dalam Kemasan (AMDK). Perbaikan sistem manufaktur merupakan salah satu usaha perbaikan yang dilakukan perusahaan agar dapat merespon perubahan. Namun sering dijumpai tindakan perbaikan atau pemeliharaan yang diambil tidak menyentuh permasalahan yang sesungguhnya. Equipment Losses merupakan salah satu permasalahan yang dihadapi. Pengukuran Efektivitas mesin produksi ini dengan metode Overall Equipment Effectiviness yakni metode yang dikenalkan oleh Nakajima Seicih melalui Japan Institute Productivity Maintenance. Metode OEE ini mengalikan tiga faktor utama yang mempengaruhi efektivitas yakni availability rate, performance rate dan quality rate. Kemudian dilakukan analisa Six Big Losses, 6 kerugian yang menyebabkan mesin downtime. Pengukuran nilai availability rate selama 4 minggu berturut-turut pada saat 16 Juli 2012 sampai dengan 12 Agustus 2012 adalah 72,39%; 78,75%; 80,38%; 79,75. Untuk performance rate sebesar 97,76%; 98,62%; 98,67%; 98,94%. Quality rate 99,98%; 99,98%; 99,94%; 99,98%. Nilai OEE yang dihasilkan adalah 70,75%; 77,64%; 79,26%; dan 78,88%. Nilai OEE mesin line 600 ml AQUA masih menyisakan banyak ruang perbaikan dan pengembangan untuk menuju standar OEE internasional 85%. Faktor yang mempengaruhi nilai OEE adalah waktu setup & adjustment losses, faktor ini disebabkan oleh kejadian waktu setup, penyesuaian, waktu penggantian material, dan warm-up yang lama.

PT Tirta Investama Cianjur is a company engaged in the production of Bottled Drinking Water. Improvement manufacturing system is one step that do of company to respect the change. But, often seen that repair or maintenance that took cannot fixed the real problem. Equipment Losses is one of problem that must be fixing. Measuring of production machine effectiviness with Overall Equipment Effectiviness method which know by Nakajima Seichi by means of Japan Institute Productivity Maintenance. The OEE method is calculate three factor that can be influence the effectiviness that is availability rate, performance rate and quality rate. And then did the Six Bog Losses analize, six losses which causing downtime machine. Measuring score of availability rate doing during four weeks, July 16th 2012 until August 12th 2012, the score of availability rate are 72,39%; 78,75%; 80,38%; 79,75. The score of performance rate are 97,76%; 98,62%; 98,67%; 98,94%. And the score of Quality rate are 99,98%, 99,98%, 99, 94% and 99,98%. The score of OEE has been result are 70,75%, 77,64%, 79,26% and 78,88%. The score of OEE line machine 600 ml AQUA it still gave many space to repair and improvement to concern 85% OEE International standar. In AQUA, the factor can be influence the OEE score is setup and adjustment time. The factor causing by setup time, standarization, time adjustment and warm up.
