      Abstract
      PT. Sari Multi Utama (SMU) merupakan salah satu perusahaan yang memproduksi botol plastik jenis PET (Polyethylene Terephthalate). Salah satu kendala yang dihadapi adalah penentuan kinerja serta penggunaan energi secara akurat pada mesin stretch blow moulding (CPSB CSS 3000). Perawatan mesin yang dilakukan oleh PT. SMU hanya menggunakan metode korektif yang berdampak pada waktu downtime yang tinggi dan rendahnya produktivitas. Penelitian ini bertujuan untuk melakukan analisis downtime mesin, analisis kebutuhan energi dan optimalisasi kinerja mesin dengan metode perawatan preventif dan korektif. Hasil analisis menunjukkan rata-rata penggunaan energi listrik dan manusia saat dilakukan perawatan secara korektif sebesar 33.758,13 kWh, setelah dilakukan perawatan secara preventif dan korektif turun menjadi 29.432,74 kWh. Energi spesifik produk turun dari 0,025 kWh/pcs menjadi 0,022 kWh/pcs. Produktivitas mesin sebelumnya sebesar 97% dan setelah dilakukan perawatan preventif dan korektif meningkat menjadi 99%. Total downtime mesin dapat diturunkan dari sebelumnya 14,3 jam menjadi 4,9 jam. Tindakan perawatan secara preventif dan korektif pada mesin CPSB CSS 3000 mampu menurunkan downtime hingga 65,73 % dan meningkatkan produktivitas mesin hingga 2,06 %.
       
      PT. Sari Multi Utama (SMU) is one of the companies that produces PET (Polyethylene Terephthalate) type plastic bottles. One of the obstacles faced is the determination of performance and accurate use of energy in stretch blow moulding machines (CPSB CSS 3000). Machine maintenance carried out by PT. SMU only uses corrective methods that have an impact on high downtime and low productivity. This study aims to analyze machine downtime, analyze energy needs and optimize machine performance with preventive and corrective maintenance methods. The results of the analysis showed that the average use of electrical and human energy when corrective treatment was carried out 33,758.13 kWh, after preventive and corrective treatment decreased to 29,432.74 kWh. Product specific energy rose from 0.025 kWh/pcs to 0.022 kWh/pcs. The productivity of the previous machine was 97% and after preventive and corrective maintenance was carried out increased to 99%. The total engine downtime can be lowered from the previous 14.3 hours to 4.9 hours. Preventive and corrective maintenance actions on the CPSB CSS 3000 machine are able to reduce downtime by up to 65.73% and increase machine productivity by up to 2.06%.
