Abstract

S45C steel is widely used in the industrial world, one of which is machining construction. problems that often occur in the engine components are worn out, broken, cracks that can be caused due to overload (over load), so the construction design is not as expected. With S45C steel is widely used in the industrial world, one of which is machining construction. problems that often occur in the engine components are worn out, broken, cracks that can be caused due to overload (over load), so the construction design is not as expected. With the above problems, it is desirable for a construction material that is hard and also resilient to prevent damage. Then in order to obtain good results, the components of the machines are then given heat treatment such as hardening which aims to improve the properties of the metal.From the results of testing the hardness obtained the highest value on the quenching test. In impact testing for raw material specimens with an average value of 0.811 J / mm2, in the quenching pesimen the average value was 0.483 J / mm2 and in the tempering tempering was 1.282 J / mm2. From the results of the impact testing, the highest values were found in the tempering templates. The microstructure of JIS S45C steel after heating undergoes a change in microstructure wherein the specimens of tempering ferrite and pearlite structures get smaller and spread, this is due to slow cooling, in contrast to specimens quenching because heat treatment is carried out through temperature and rapid cooling with water media so that the structure does not have enough time to diffuse.

Abstract

Gear pump (pompa roda gigi) adalah jenis pompa positive displacement dimana fluida akan mengalir melalui celah-celah roda gigi dengan dinding rumahnya disebut sebagai pompa karena fluida yang dialirkan pada umumnya berupa cairan (liquid) atau bubur (slurry). Sedangkan pompa positive displacement berarti pompa tersebut menghisap sejumlah fluida yang terjebak yang kemudian ditekan dan dipindahkan ke arah keluaran (outlet). Gear pump sering digunakan untuk aplikasi hydrolic fluid power. Dalam pengoperasiannya sebuah komponen gear pump excavator dapat mengalami kegagalan, meskipun komponen tersebut masih dalam keadaan bagus/ baru. Untuk menganalisa penyebab terjadi kegagalan gear pump ini dilakukan pengujian yang meliputi pengujian yang bersifat merusak (destructive material testing) menggunakan uji kekerasan dan pengujian yang tidak merusak (non-destructive material testing) menggunakan uji fraktografi, metallografi dan pengujian komposisi kimia. Dari hasil pemeriksaan di labor menunjukan bahwa Gear Pump Excavator mengalami kerusakan pada gigi penggerak di bagian luar dan gigi bagian dalam, photo makro roda gigi bagian luar dalam penampang melintang menunjukan adanya cacat Deformasi / Perubahan Bentuk akibat beban bentur pada permukaan roda gigi. Roda gigi yang menerima beban putar/ gesek mengalami aus sesuai dengan arah putaran geardan pada permukaan patahan dan menunjukkan terdapatnya inklusi yang terkonsentrasi mengarah ke permukaan material gear pump excavator sehingga menyebabkan terjadinya aus. Pada material gear pump excavator yang mengalami kegagalan bila dilihat dari bentuk patahannya termasuk kepada jenis beban fatik karena sebelum patah gear pump excavator mengalami cacat deformasi.

Abstract

Total Productive Maintenance (TPM) adalah suatu prinsip manajemen untuk meningkatkan produktivitas dan efisiensi. Menurut Moubray J, dkk. (1997), Maintenance atau pemeliharaan adalah suatu kegiatan yang dilakukan secara berulang-ulang dengan tujuan agar peralatan selalu memiliki kondisi yang sama dengan keadaan awalnya. Menurut Much. Djunaididkk (2013) Total Productive Maintenance(TPM) merupakan pencapaian efisiensi pemeliharaan mandiri melalui satu sistem yang lengkap berdasarkan keikutsertaan seluruh karyawan.Tidak tepatnya penanganan dan pemeliharaan mesin akan mengakibatkan kerugian – kerugian dalam kategori Six big losses.Tahap pertama dalam usaha peningkatan efisiensi produksi pada perusahaan ini adalah dengan melakukan pengukuran efektifitas mesin dryer twind dengan menggunakan metode Overall Equipment Effectiveess (OEE) yang kemudian dilanjutkan dengan pengukuran OEE Six big losses untuk mengetahui besarnya efisiensi yang hilang pada ke enam factor Six big losses. Dari ke enam factor tersebut selanjutnya di cari factor yang memberikan kontribusi terbesar yang mengakibatkan besarnya efisiensi pada mesin dryer twind .dengan diagram sebab akibat dapat di analisa masalah sebenarnya yang menjadi penyebab utama tingginya kerugian yang mengakibatkan rendahnya effisiensi mesin dryer twind. Kesimpulan yang dapat diambil pada mesin dryer twind bahwa nilai OEE untuk periode Februari 2014 – Januari 2015 berkisar antara 77,15% sampai 82,72% kondisi ini menunjukan bahwa kemampuan mesin dryer twind dalam mencapai target dan dalam pencapaian efffectivitas penggunaan mesin/ peralatan belum mencapai kondisi yang ideal (?85%)
