AbstrakRemote Control Weapon Station (RCWS) Senjata Mesin Ringan (SMR) dibuat untuk mendukung tugas pokok TNI AD dalam rangka melaksanakan tugas operasi tempur, sehingga diperoleh daya guna tempur yang lebih efektif, efisien, profesional dan modern dalam mendukung terciptanya kemandirian teknologi Alutsista TNI AD. Perencanaan dan pembuatan alat dibangun dengan menggunakan perangkat keras dan perangkat lunak. Perangkat keras yang digunakan yaitu Joystick, Motor DC, mikrokontroler ATmega32, Driver L298, IRF3205 dan mekanik. Sedangkan perangkat lunak yang digunakan yaitu Basic Compiler (BASCOM) sebagai alat pengendali. Dalam pembuatan alat yang dimaksud agar dapat berfungsi dengan baik, maka diperlukan pemahaman yang mendalam tentang karakteristik dan cara kerja komponen-komponen yang digunakan. Hal ini perlu dikuasai sebaik-baiknya untuk menghindari kesalahan penggunaan komponen yang mengakibatkan kegagalan dalam pembuatan alat. Pada perencanaan hardware akan meliputi seluruh perihal yang digunakan pada sistem. Pada perencanaan software merupakan piranti lunak meliputi flowchart dan software secara umum. Perangkat tersebut saling terintegrasi sehingga dalam kerjanya akan maksimum sesuai apa yang diharapkan.

This research aimed to: (1) producing ignition system practice learning products and (2) to know the feasibility of ignition system practice learning media in automotive electrical system courses in the Department of Automotive Engineering Education Yogyakarta State University.This study was a research and development using the 4D development model (define, design, develop, and dissemination). The subjects of this study were 38 students of the Department of Automotive Engineering Education. Data collection techniques were carried out by observation and closed questions to get preliminary data from automotive workshops as well as students of automotive engineering education and questionnaires to find out the results of practical learning media from experts and users. The feasibility data analysis is done by describing it into 5 categories as on the Likert Scale.The results of this development research are: (1) the resulting ignition system practice learning media products in the form of job sheets which have word format and video tutorial with MP4 format and (2) the feasibility of this practice learning media is determined by material experts (4.74) for job sheets that are categorized as very feasible and (4.95) for video tutorials that are categorized as very feasible, eligibility based on media experts (4.78) for job sheets that are included in the very feasible category and (5.00) for video tutorials that were in the very feasible category, the response of students as users received a rating (4.04) for the job sheet that was in the appropriate category and (4.13) for the video tutorial which was in the appropriate category. So that the development of ignition system practice learning media is feasible to use.

This study presents an investigation on the motion control of 3 phase motor using wireless communication. The wireless communication network used is Bluetooth which supports Arduino Uno, so that the motor rotation can be controlled via a smartphone. Control system is used to adjust 3 phase motor rotation. The method used in the development of 3 phase motor rotation control system are analysis of needs, control system design, development of systems, testing and performance measurement, and improvement the system. The results of this study indicate that the 3 phase motor rotation control system can work according to the design. When Bluetooth HC-06 module receives a signal from a smartphone via Bluetooth Electronics, then the signal is sent to Arduino Uno and forwarded to DC Relay and proceed to Omron MKP3-I Relay. When using 3.0 version of bluetooth, the farthest distance that can be received by the Bluetooth HC-06 module without an obstacle is 21 m, whereas if there is an obstacle, the signal can only be received in 16 m. Meanwhile, when using 4.1 version bluetooth, the farthest distance that can be received by the Bluetooth HC-06 module without an obstacle is 26 m, whereas if there is an obstacle, the signal can only be received in 19 m.
