Abstract

Pada era otomatisasi, pekerjaan secara manual dapat digantikan dengan cara yang otomatis. Operasi tetap merupakan bagian penting dari sistem meskipun dengan mengubah tuntutan pada input fisik sebagai tingkat mekanisasi. Mesin pemotong bahan baku material komposit dengan serat alam merupakan mesin dengan sistem kerja mekanik. Dimana, mesin ini menggunakan sistem pneumatik sebagai penggerak dari mata pisau pemotong serat alam. Penelitian ini bertujuan untuk mencari alternatif yang lebih cepat dalam menggerakkan lengan angkat pada saat memotong dan mendorong serat alam. Pengambilan data pada penelitian ini adalah dengan cara mengukur waktu pemotongan serat dengan variasi tekanan yang diberikan ke sistem. Data penelitian yang diperoleh adalah waktu pemotongan serat dan kecepatan piston. Alat pemotong serat sistem pneumatik ini mampu memotong dalam waktu 0.41 detik dengan kecepatan piston 549 mm/detik pada tekanan udara 0,5 Mpa. Makin besar tekanan udara yang diberikan makin singkat waktu yang dibutuhkan untuk memotong serat alam, dan makin besar nilai kecepatan piston.Kata-kata kunci : otomatisasi, pneumatik, serat alam

Abstract

The corrosion process occurs in almost all materials, especially metals, slowly but surely, which can cause a material to have a limited service life. Corrosion cannot be prevented but the rate can be reduced. One of the methods to inhibit the effective corrosion rate is by giving epoxy primer treatment. This study aims to examine the effect of adding epoxy primer on the corrosion rate of low carbon steel immersed in a 3.56% NaCl solution. This research was conducted using 27 specimens in 9 vessels, each vessel contained 3 specimens immersed in low carbon steel without treatment, oil paint and epoxy primer. Volume of 1 liter of 3.56% NaCl solution for 1 vessel. The results of this study indicate that the epoxy primer is able to inhibit the corrosion rate well. The reduction in weight of low carbon steel treated with oil paint is much greater than that of untreated low carbon steel using epoxy primer. The lowest corrosion rate was given by applying epoxy primer in 20 days of immersion with an average value of 0.0003761136666 mpy and the highest corrosion rate with paint treatment in 10 days of immersion with an average value of 0.004513367 mpy.

The reduction in weight of low carbon steel treated with oil paint is much greater than that of untreated low carbon steel using epoxy primer. The lowest corrosion rate was given by applying epoxy primer in 30 days of immersion with an average value of 0.001001695 mpy and the highest corrosion rate without treatment in 15 days of immersion with an average value of 0.005008473 mpy.
