Abstract

Fungsi rem pada kendaraan adalah untuk membatasi gerakan pada komponen rem yang bertujuan untuk memperlambat serta menghentikan roda penggerak sehingga kendaraan jadi berhenti. Penelitian ini menggunakan metode Failure Mode Effect Analisis ( FMEA ) untuk mengetahui penyebab kegagalan pada system pengereman kendaraan berat jenis mobil trailer, hasil analisis perhitungan nilai FMEA dengan RPN (Risk Priority Number) di dapatkan 2 componen pneumatik yang paling sering mengalami kegagalan yaitu Componen Control valve trailer brake sebesar 189, dan component Chamber Brake 147, hasil analisis dengan menggunakan FTA(Fault Tree Analysis) faktor yang mempengaruhi kegagalan pada komponen pneumatik brake system adalah faktor manusia & mesin.

Abstract

Power window system is a series of electrical body system that functions to facilitate the driver when opening and closing the glass door electrically by using a power window switch mounted on the inside side of the door, where the manual power window system driver must rotate the glass opening lever to raise and lower the door glass. The power window motor rotates when the power window switch is pressed. The power window motor rotation will turn up and down through the door glass regulator to open or close the door glass. The power window application process includes preparation of component placement design and preparation of materials to be used such as motor power windows, relays, fuses and switches, after all is ready, then the installation of components such as motor power windows to the regulator which has been modified in the form of additional plates for the holder The motor, after the power window regulator is ready, then assembles the electrical system and the installation of connections or sockets to each component. After the regulator and the electrical system are ready then install the switch holder on the door trim that has been prepared. The results of the power window application obtained power window can work in accordance with its function using a switch, namely the glass door can move up and down according to the position of the switch button pressed on each switch and from the results of the measurement process that the average voltage requirement for the power window to the position goes up 11.5 V while the position goes down 12V. The average time needed to raise the glass on the door 3.63 seconds and to lower the glass door takes 2.78 seconds
