<![CDATA[Vibration is a response from a mechanical system that occurs due to the excitation force given.Vibration on the Main Engine foundation is very influential on the construction. As in ro-ro ships thatexperience changes to the main engine, which in the end also requires the addition of plates on the mainengine foundation to fulfill the alignment value between the main engine and the gearbox. This FinalProject discusses the vibrations that occur in the ship's main engine foundation using mathematicalmodeling methods. Mathematical modeling is used to determine the system that works in a mathematicalstatement. Preliminary analysis conducted to determine the value of mathematical modeling. Thedeflection and stiffness values also affect the vibration response that occurs in the main enginefoundation. This mathematical modeling produces a vibration response in the form of a vibrationresponse equation and the resulting equation can produce a graph by entering the equation into theMatlab software. The vibration response graph uses two variations, namely at 85% RPM and 100% RPM.From the calculation results obtained amplitude values of 0.179 mm at 85% RPM and 0.199 mm at 100%RPM before adding the plate. And has an amplitude value of 0.172 mm at 85% RPM and 0.191 mm at100% RPM after adding the plate. According to the ABS the recommended displacement is below 1.0 mmand the probability of damage is above 2.0 mm. This shows that the vibrations that occur in this structureare permitted.]]>

<![CDATA[Kurangnya peran pemerintah dan diskriminasi dari lingkungan membuat para penyandang disabilitas semakin tertinggal dalam hal transportasi. Oleh karena itu mereka memilih untuk memodifikasi alat transportasi sepeda motor roda dua menjadi roda tiga untuk mobilitas mereka. Namun, masih terdapat beberapa hal yang masih dapat dikembangkan lagi, hal itu dikarenakan belum adanya desain standar khusus kendaraan bermotor untuk para penyandang disabilitas. Produk yang sudah ada saat ini dibandrol dengan harga mahal, sehingga para penyandang disabilitas merasa berat untuk membeli produk tersebut, dan memilih memodifikasi motor mereka sendiri dengan peralatan dan ilmu seadanya. Oleh karena itu pada penelitian ini akan dilakukan analisa dengan menggunakan metode konsep desain. Dimana hasil dari proses konsep desain ini akan terpilih satu konsep desain modifikasi sepeda motor roda tiga yang terbaik bagi penyandang disabilitas. Hasil yang didapat dari pemilihan konsep desain yang telah dilakukan terpilih konsep desain kelima.

<![CDATA[PT. Marufuji Kenzai Indonesia one of furniture manufacture company in east java which use elbow stapler machine to assist production process. This elbow stapler machine is used to unite the elbow portion of the fiberboard (hardboard) material. However, the elbow stapler machine used is only able to be used to unite one side only. This of course inhibits the production process considering the number of stapler engines is not proportional to the number of fiber board material (hardboard) that is done. The method used to overcome the problem of delay in the work of fiberboard material (hardboard) is to make a two-sided flexible wooden elbow stapler machine using electropneumatic system. The working system of this machine will use three pneumatic cylinders where two cylinders are used for the stapler and one large cylinder is used to push the stapled material. Making this machine will be through several stages such as design, detail drawing, framework analysis, simulation, electropneumatic system design, to the assembly stage (assembly). Making the flexible wooden elbow stapler machine is expected to be able to overcome the problems that often occur in the process stapler material that has been produced. So that the work is usually done by one operator can be helped by the performance of this flexible wooden elbow stapler machine. So no more stacking of material in the stapler that resulted in disruption of some further process.]]>
