Abstract

ABSTRACT

PT. XYZ has implemented Total Productive Maintenance (TPM) to improve the efficiency and effectiveness of manufacturing companies as a whole. However, the implementation is still not optimal and seen from not achieving the production target. This study aims to measure the value of the effectiveness of equipment, find the root causes of problems and provide suggestions for improvement. The study was conducted on a kneader machine that had the highest breakdown rate. This research begins by measuring the overall equipment effectiveness (OEE) achievement value, then identifying the six big losses that occur. The results showed that the average OEE value on the kneader machine was 81.62%, the effectiveness value was classified as very low because the standard OEE value for world-class companies was ideally 85%. The biggest factor influencing the low OEE value is the performance rate with a factor of six big losses in reducing spees losses of 42.66% and idling and minor stoppages of 31.27% of all time losses. What causes the magnitude of losses consists of human, machine, material, method, and environmental factors. Human and machine factors are the most dominant factors. To reduce these losses, companies should provide skills and knowledge training to operators about the signs of damage to the equipment. In addition, operators are given additional work in the form of equipment maintenance that is often used in work so that maintenance work can be more focused. Then the company must pay more attention to the comfort of the operator at work so that fatigue can be reduced and operator productivity is increased and increase operator awareness of the tools they use.

ABSTRAK

XYZ telah menerapkan Total Productive Maintenance (TPM) guna meningkatkan efisiensi dan efektivitas perusahaan manufaktur secara menyeluruh. Namun dalam pelaksanaannya masih belum optimal dan dilihat dari tidak tercapainya target produksi. Penelitian ini bertujuan untuk mengukur nilai efektivitas peralatan, mencari akar penyebab masalah dan memberikan usulan perbaikan. Penelitian dilakukan pada mesin kneader yang selama ini memiliki tingkat breakdown yang tertinggi. Penelitian ini dimulai dengan mengukur pencapaian nilai overall equipment effectiveness (OEE), kemudian mengidentifikasi six big losses yang terjadi. Hasil penelitian menunjukan bahwa rata-rata nilai OEE pada mesin kneader sebesar 81,62%, nilai efektivitas ini tergolong sangat rendah karena standar nilai OEE untuk perusahaan kelas dunia idealnya adalah 85%. Faktor terbesar yang mempengaruhi rendahnya nilai OEE adalah performance rate dengan faktor persentase six big losses pada reduce spees losses 42,66% dan idling and minor stoppages sebesar 31,27% dari seluruh time losses. Yang menyebabkan besarnya losses terdiri dari faktor manusia, mesin, material, metode, dan lingkungan. Faktor manusia dan mesin merupakan faktor yang paling dominan. Untuk mengurangi kerugian tersebut, perusahaan sebaiknya memberikan pelatihan skill dan pengetahuan kepada operator tentang tanda-tanda kerusakan alat tersebut. Selain itu operator diberikan tambahan pekerjaan berupa perawatan peralatan yang sering digunakannya dalam bekerja sehingga pekerjaan bagian maintenance bisa lebih berfokus. Kemudian perusahaan harus lebih memperhatikan kenyamanan operator dalam bekerja sehingga kelelahan bisa dikurangi dan produktivitas operator lebih meningkat serta meningkatkan kepedulian operator terhadap alat yang digunakannya.
