Abstrak Keamanan merupakan hal sangat penting bagi setiap orang. Rumah yang sering ditinggal pemiliknya dapat dimanfaatkan oleh pencuri untuk melakukan aksinya. Oleh karena itu diperlukan sistem keamanan rumah yang efektif agar pemilik rumah dapat mengetahui informasi apabila rumahnya dibobol oleh pencuri. Penulis merancang sebuah sistem keamanan rumah dengan memanfaatkan teknologi RFID yang di lengkapi dengan sensor PIR dan modul GSM sebagai sistem informasi peringatan SMS, dimana semua sistemnya diolah dalam sebuah mikrokontroler ATmega328. Tujuan dari penelitian ini untuk mengganti kunci konvesional dengan kunci solenoid sehingga sulit untuk diduplikat serta mengurangi kesempatan aksi pencurian ketika rumah dalam keadaan kosong. Metode penelitian yang digunakan antara lain dimulai dari pengumpulan data (observasi, wawancara dan studi pustaka) serta pembuatan alat (planning, analisis, desain dan testing). Berdasarkan hasil pengujian diperoleh bahwa kunci solenoid dapat bekerja sesuai dengan kartu akses RFID yang diberikan. Sensor PIR dan modul GSM dapat bekerja dengan baik saat pencuri masuk kedalam rumah, sehingga rumah menjadi aman ketika ditinggalkan oleh pemiliknya. Kata Kunci: RFID, Sensor PIR, Modul GSM, ATmega328 Abstract Security is very important for everyone. Homes that are often left the owner can be used by thieves to perform the action. Therefore required an effective home security system so that homeowners can find out information if the house burglarized by thieves. The author designed a home security system by utilizing RFID technology that is equipped with PIR sensor and GSM module as SMS warning information system, where all the system is processed in an ATmega328 microcontroller. The purpose of this research is to change the conventional key with the solenoid key so that it is difficult to duplicate and reduce the chance of theft action when the house is empty. Research methods used, among others, starting from data collection (observation, interview and literature study) as well as making tools (planning, analysis, design and testing). Based on the test results obtained that the solenoid key can work in accordance with the given RFID access card. PIR sensors and GSM modules work well when thieves enter the house, so the house becomes secure when left by the owner. Key Word: RFID, PIR Sensor, GSM Module, ATmega328

This study aimed to develop the feasibility of the Mahârah al-Istimâ’ test instrument for electronic-based Arabic students using the Kahoot! application at UIN Sunan Kalijaga Yogyakarta. The method used in this research is the research and development of  Borg and Gall model through analysis, design, and testing. Eligibility is based on the expert validator test and the final operation field test. The results of the study can be concluded that: 1) Preparation of the Test Instrument refers to the 5 objectives or indicators of Mahmud Kamil an-Naqah into 50 questions in product design using the Kahoot! application, 2) From the results of the expert validator it is known that the results of the material quality are obtained by an average 5.37 and the media quality of the application is obtained by an average of 4.75 (very feasible), 3) After being obtained from the main field test to 20 students there are 6 questions or 12% that are not feasible because they are invalid and have not discrimination index, then the author revise and test the revision results to 70 students with 100% valid results and are suitable for use.

This paper proposed an application that supports visually impaired users in the community by providing voluntary audio support for readable content. The application, Basirah, allows visually impaired users to post audio request for reading text. Volunteers are able to view these requests and offer their response as recorded audio links. The application is developed for iOS devices and supports requests in English and allows for multi-lingual responses for volunteers. This paper presents Basirah and walks through the analysis, design, and testing phases of development. Preliminary testing was carried out on Basirah, where it has shown promising results and contribution.

Exports and imports are driving the nation's economy and state revenue sources. Customs as a state agency is assigned to manage the country's income. Customs and its staff are still experiencing difficulties in reporting receipt of export and import of plant or company. One of the policy is issued, each factory or company shall make the information system to determine information about the export of finished goods and raw material imports. The problem is the lack of standardization in the information that must be made by the manufacturer or company. The problem is the lack of standardization in the information that must be made by the manufacturer or company. This study makes the design of information systems based on web-based exports and imports that can be used by all factories or companies in Indonesia, particularly in PT.Windu Eka. The design method used is the SDLC (System Development Life Cycle) Analysis, Design and Testing Prototype. This information system consists of web-based software with PHP programming and MySQL database that aims to provide information online, so the reports more accessible and faster made to be reported to Customs.

The objective of this paper is to design, analyze, and test the space frame for electric vehicle with comparison to the engine type. Therefore, in order to design the electric vehicle formula, the same requirements with some changes are considered. The space frame is designed to suit with the electric vehicle and then finite element analysis is used to determine the torsional stiffness of the frame which is verified by the torsional test. Initially, the required torsional stiffness for the electric car is 1350 Nm/deg and the mass is set to be not more than 40 kg. The numerical results and the experimental results for torsional stiffness are 960 Nm/deg and 1218 Nm/deg, respectively. Therefore, the torsional stiffness is about 25% under-predicted; anyway it can be used to predict the torsional stiffness of the frame. Due to some changes must be performed, therefore the modified frame is re-analyzed with the torsional stiffness of 1389 Nm/deg which is less than the revised required car’s torsional stiffness of 1404 Nm/deg. Anyway, the torsional stiffness of frame with battery’s case can meet the requirement. The mass of the modified frame is 50 kg which is larger than required mass due to selected sizes of steel tubes. In conclusion, the space frame can be designed and the mass can be improved further by reducing the sizes.

Position Control System

The development of a position control system using a stepper or incremental motor is described. The advantages of this type of prime mover are discussed, and a technique of integrating the stepper motor into the system is analyzed. The output signal from the error detector used in the system comes from a sampler and zero-order hold circuit. This signal controls a gate which either allows or inhibits a pulse train to drive the stepper motor. The load on the motor is an underdamped second-order system. The stepper motor output position and the reference input determine the error. The analysis includes a stability investigation using the describing-function method and a computer simulation to determine the dynamic performance of the system. The effects of noise in the system are also investigated on the computer. The equipment used to mechanize the control system is described, and results of experimentol work to determine the actual performance of the system are given.
