Sistem Pendukung Keputusan Pemilihan Ketua Osis dengan Metode Simple Additive Weighting SMK Negeri 11 Pandeglang
Sistem pendukung keputusan pemilihan ketua osis ialah aplikasi yang di dalamnya ada proses pemilihan siswa yang bisa jadi calon ketua osis. Sistem ini diperlukan karena proses yang ada, tidak mendapatkan siswa yang sesungguhnya berkompeten untuk menjadi ketua OSIS. Tujuan dari riset ini merupakan mencari calon ketua osis dengan sistem pendukung keputusan yang bisa memperhitungkan calon ketua osis yang terdapat di Sekolah Menengah Kejuruan (SMK) Negara 11 Pandeglang. Tata cara yang digunakan dalam riset ini adalah metode pengumpulan informasi yang digunakan ialah memastikan kriteria, variable kriteria, melaksanakan perhitungan. Ada pula hasil proses SAW ini berbentuk peringkat, hasil proses ini direkomendasikan selaku ketua OSIS bersumber pada kriterianya. Kata Kunci – Sistem Informasi, Ketua Osis, Metode SAW.

Read moreControl system design for an Automatic Emergency Braking system in a sedan vehicle
The Automatic Emergency Braking (AEB) systems in vehicles is one of the technologies suggested by NHTSA to be included in vehicles by default. This article presents the dynamic model of the vehicle that should be considered to design control of EAB system. After that, the design of a classic controller is presented, following of some results of simulations, which let to identify variables to measure the comfort of automatic braking, and when and in which conditions the ABS systems act over an action of AEB. Finally, the Architecture of the implementation of the braking over CAN Networks is presented.
Read moreA high temperature ultrafast isolated converter to turn-off normally-on SiC JFETs
Silicon Carbide (SiC) components are accepted devices for high temperature and high efficiency applications. Normally-on SiC JFETs are now commercialized and will be used in future power converters. However, such devices are conducting when not driven with a sufficient negative voltage, which can lead to safety issues during start-up or abnormal operation of the gate driver. Therefore, it is needed to generate an auxiliary negative voltage to turn-off the JFET in order to protect the system. Moreover, insulation is necessary to cover all failure modes. Prior papers presented solution to protect such devices but no high temperature isolated solution were demonstrated. In this paper, a solution to protect JFETs used in a high temperature (200°C) voltage source inverter is proposed. The protection circuit, components selection and characterizations for high temperature application are detailed. Experimental results are provided and validate the design of the isolated normally-on protection circuit up to 200°C.

In this article, a high temperature EMI input filter for a SiC JFET inverter is designed and tested in operating conditions at 200°C. Inverter EMI issues, design procedure, and characterizations of selected components are presented in detail. The feasibility based on industrially available materials and components is demonstrated with a low temperature dependence of the EMI spectrum.
