Penelitian ini bertujuan untuk mengetahui peningkatan efektivitas mesin coal crusher dengan menggunakan analisis deskriptif dan kuantitatif metode six sigma. Penggunaan Overall Equipment Effectiveness dan Six Big Losses untuk menentukan nilai Overall Equipment Effectiveness dan faktor dominan yang menyebabkan rendahnya kinerja mesin atau peralatan. Proses penerapan small group activity sebagai bagian dari Total Productive Maintenance dengan penerapan fase DMAIC dari analisis Overall Equipment Effectiveness (OEE), Six Big Losses, dan Fish Bone Diagram untuk menganalisa penyebab masalah yang menghambat kinerja mesin dan peralatan serta signifikansi peningkatan kinerja operasional di departemen FPM. Berdasarkan pengolahan data pada Coal Crusher dengan metode OEE dan Six Big Losses faktor yang paling dominan menyebabkan rendahnya kinerja mesin adalah Reduced Speed Losses dengan persentase 58,82% dan Equipment Failure Losses dengan persentase 62,21% pada mesin Coal Crusher yang mempengaruhi efektivitas dan produktivitas mesin  tersebut. Menggunakan diagram pareto untuk menganalisis data losses yang ada sehingga akar permasalahan dapat ditemukan. Selanjutnya dengan analisis fish bone diagram didapatkan saran-saran langkah pencegahan dalam mengurangi jumlah losses time. Langkah perbaikan sistem yang dilakukan di Departemen FPM dengan penerapan Small Group Activity sebagai control secara berkelanjutan memberi peningkatan produktivitas terhadap kinerja Coal Crusher di akhir periode Desember 2020 yaitu diperoleh rata-rata nilai Overall Equipment Effectiveness (OEE) yaitu sebesar 87% dan telah memenuhi nilai standar dunia 85%. Dengan adanya peningkatan kinerja diharapkan kegiatan proses produksi dapat berjalan efektif, efisien, serta energi dapat digunakan secara optimal.

PT. KPS is one steel company in Indonesia that produces steel products in the form of slab and plate that is marketed in the country up to foreign countries. Cold leveller machine is a machine that serves to flatten the surface of the plate. Problems occurred in the machinery that is often experienced a breakdown so that the plate with uneven surfaces more and more because of the time machine working on the wane. This research aims to quantify the value of the overall equipment effectiveness (OEE), calculating the factor of six big losses and figure out the root cause of the problem, the dominant factor of the six big losses with the fishbone diagram. The OEE value obtained on the engine cold leveller is 82%. The biggest factor that causes the low effectiveness of the machine that is the reduced speed losses amounting to 11.59% and equipment failure losses amounted to 6.04%. The proposed corrective actions is prioritizing the main TPM pillar 3 that is autonomous maintenance, quality maintenance, training and education.Keyword : fishbone diagram, overall equipment effectiveness (OEE), pareto, the six big losses, total productive maintenance (TPM)PT. KPS adalah salah satu perusahaan baja di Indonesia yang memproduksi produk baja berupa slab dan plate yang dipasarkan di dalam negeri hingga ke luar negeri. Mesin cold leveller merupakan mesin yang berfungsi meratakan permukaan plate yang tidak rata. Permasalahan yang terjadi pada mesin tersebut yaitu sering mengalami breakdown sehingga plate dengan permukaan yang tidak rata semakin banyak karena waktu bekerja mesin semakin berkurang. Penelitian ini bertujuan untuk menghitung nilai overall equipment effectiveness (OEE), menghitung nilai faktor six big losses dan mengetahui akar penyebab masalah yang dominan dari faktor six big losses dengan fishbone diagram. Nilai OEE yang didapat pada mesin cold leveller adalah sebesar 82%. Faktor terbesar yang menyebabkan rendahnya efektifitas mesin yaitu reduced speed losses sebesar 11,59% dan equipment failure losses sebesar 6,04%. Tindakan perbaikan yang diusulkan adalah memprioritaskan 3 pilar utama TPM yaitu autonomous maintenance, quality maintenance, training dan education.Kata Kunci: fishbone diagram, overall equipment effectiveness (OEE), pareto, six big losses , total productive maintenance (TPM)

Total Productive Maintenance

Metode six sigma adalah suatu metode yang populer,  yang kerap digunakan dalam meningkatkan produktivitas dan kualitas, dengan analisis yang terperinci dalam menentukan penyebab masalah dan mengusulkan perbaikan yang tepat dalam menguraikan masalah pada perusahaan. Begitu banyak pendekatan yang dapat dipakai dalam metode six sigma, salah satunya yaitu DMAIC. Tujuan pendekatan DMAIC dalam meningkatkan Total Productive Maintenance (TPM) pada mesin dies casting zinc dibahas dalam penelitian ini. Pada penelitian ini, penyebab utama adalah rendahnya nilai OEE pada pada mesn dies casting dengan persentase nilai 75%, yang mana nilai tersebut masih jauh dari nilai yang telah di tetapkan oleh Japan Institute of Plant Maintanance (JIPM). Analisis dilakukan untuk mengetahui akar masalah yang menyebabkan produktivitas mesin dies casting rendah yang mempengaruhi nilai OEE rendah. Metodologi six sigma dalam pendekatan DMAIC dalam meningkatkan TPM berhasil diterapkan untuk menaikkan nilai OEE sebesar 85% yang semula 75%. serta dapat mengurangi waktu breakdown pada mesin, yang semula rata-rata waktu breakdown 215 menit/bulan menjadi 152 menit/bulan. Keterbatasan pada penelitian ini, hanya melakukan penelitian pada satu mesin yang mempunyai kerusakan yang paling tinggi pada saat breakdown mesin terjadi.

The objective of this research is to improve the overall result and pass percentage of students in degree level technical institutions by eliminating the failure causes using lean six sigma method. A case study was carried out in a degree level technical institute, which has a total intake of 720 students producing 54% of results for the past five years. Taking as a challenge issues to produce more than 75% of results, it was considered to carry out a study using lean six sigma approach. In this research five stage methodology of six sigma i.e. DMAIC have been used to reduce the parameters that affect the system. Failure mode effect analysis, histogram, process capability analysis and fish bone diagram methodologies were also adopted to analyze the depth of the issue and to identify the critical factors that requires to be controlled and to improve by implementing the solutions and remarks received from the stakeholders. From the results it was found that, through this approach the pass percentage level of the technical institute had increased from 54% to 75% by identifying and reducing the appropriate source of failures.
