P PT. Pratama Abadi Industri merupakan perusahaan yang bergerak pada bidang pembuatansepatu olahraga. Penelitian dilakukan di departemen factory 1 yang merupakan tempatpembuatan bagian upper sepatu. Mesin laser cutting merupakan salah satu dari mesin padaproses pembuatan upper sepatu. Mesin ini dijadikan objek penelitian dikarenakan memilikijumlah waktu kerusakan tertinggi dibandingkan dengan mesin lainnya. Permasalahanutama adalah terjadinya breakdown pada komponen mesin meskipun sudah diterapkannyapreventive maintenance. Hal tersebut menunjukkan belum optimalnya penerapan metodetersebut. Breakdown yang terjadi dapat menurunnya jumlah produksi sehingga targetproduksi tidak dapat tercapai. Penelitian ini akan memberikan solusi dalam melakukanperawatan pada komponen mesin menggunakan pendekatan Total Productive Maintenance(TPM). Dalam mempersiapkan penerapan TPM maka dilakukan perhitungan OverallEquipment Effectiveness (OEE), dimana dari hasil perhitungan didapatkan nilai OEE untukbulan Agustus-Oktober 2016 sebesar 83.99%, 84.48% dan 80.8% dimana nilai tersebutmasih dibawah 85% yang merupakan world standard OEE. Dari hasil perhitungan six biglosses didapatkan nilai losses terbesar terdapat pada reduced speed losses (71.18%) danbreakdown losses (25.98%). Reduce speed losses dapat terjadi karena pengurangankecepatan produksi dari kecepatan desain peralatan tersebut, sedangkan breakdown lossesterjadi karena peralatan mengalami kerusakan, tidak dapat digunakan dan memerlukanperbaikan atau penggantian . Diagram fault tree analysis (FTA) menunjukkan secara rincibagian komponen serta alasan penyebab mesin mengalami breakdown. Hasil perhitunganprobabilitas kegagalan yang didasari pada FTA, didapatkan komponen exhaust ductingblower, transmission system dan epsilon-type mesh belt merupakan komponen yangmemiliki probabilitas kegagalan yang tinggi, yakni 0.3524, 0.04787 dan 0.04787. Usulanperbaikan didasarkan pada delapan pilar TPM yang berfokus pada pilar autonomousmaintenance, focused improvement, planned maintenance, training and education, dansafety, health & environment. Usulan yang diberikan berupa guidance untuk aktivitasautonomous, penambahan tahapan perawatan preventive, pembuatan jadwal preventivemaintenance, training TPM, serta penerapan 5S pada lingkungan kerja mesin

P PT. Pratama Abadi Industri is a company which produce sport shoes. This research wasconducted in the upper shoe line which is located in factory 1 department. Laser cuttingmachine is one of the machines used in said department. Laser cutting machine became theovject of research because it has the highest amount of breakdowns compared to othemachines in the upper shoe line. The main problem is the occurrence of breakdown despitethe fact that this company had applied preventive maintenance as their maintenancepolicy. That being said, it seems the practice of such method was not optimally conducted.Total Productive Maintenance (TPM) is an approach that will be used to solve theproblem in this research. In order to apply the TPM approach, Overall EquipmentEffectiveness (OEE) needs to be calculated first, in which the OEE for August, Septemberand October 2016 are respectively, 83.99%, 84.48% and 80.8%. This indicates that theOEE was still below the World Standard OEE which is 85%. Based on the calculation ofsix big losses, the largest contributing factors to the time loss was reduced speed losses(71.18%) and breakdown losses (25.98%). Reduced speed losses may happen due to thedecreasing of speed of production compared to its original design, while breakdown lossesmay happen because the components of the machine experienced failure, unable to beused, require to be repaired or replaced. Fault Tree Analysis (FTA) diagram shows thecomponents in a machine and the cause of failure/breakdown in detail. Based on thecalculation of probability of failure from the FTA, the exhaust ducting blower,transmission system and epsilon-type mesh belt are the components which have the highestnumber of probability which are respectively, 0.3524, 0.04787 and 0.04787. The proposedimprovements are based on TPM’s 8 pillars, in which in this research, only 5 pillars arechosen: autonomous maintenance, focused improvement, planned maintenance, trainingand education, and safety, health & environment. The proposed improvements are:autonomous maintenance guidance, an upgraded preventive maintenance procedure,preventive maintenance schedule, TPM training, and applying the 5S foundation.
