Simulasi Penentuan Sudut Arah Kiblat Dengan Metode Segitiga Bola Menggunakan Bahasa Pemrograman Gui Matlab R2009

This reseach is about qibla location measurement using analytical mathematics of spherical trigonometry. The analytical mathematics of spherical trigonometry is simulated using mathematics software. In This research using MATLAB R2009 mathematics software. Since this software user easily to use by newbie user, the language of this software simulated in GUI MATLAB R2009 programmer language. This programmer language make interactif learning between the user and the program. The important input parameter of this software are coordinat location of area then the user can measument angle magnitude qibla location convenient with coordinat location

Purwa Rupa Sistem Pengaman Sepeda Motor Berbasis IoT (Internet Of Things

The case of motorbike theft is one of the common problems in the community that needs to be found a solution. One of solutions to secure motorbikes from potential theft is to install smart vehicle technology (smart vehicl e). This paper describes the design of IoT vehicle safety systems using Arduino Mega microcontroller, fingerprint sensor, ESP8266 and Blynk applications on smartphones. For the experiment, this study uses an automatic transmission motorbike that represents the public motorcycle model. For research methods, this study uses three stages of design. The first stage is to compile the prototype hardware of a motorcycle security system using a fingerprint sensor, and a microcontroller. The second phase, IoT that uses a notification system on ESP8266-based smartphones and Blynk applications are designed. In the third stage, the security system and notification system sent via the smartphone are combined. In the results of the first phase of the trial, five people (whose fingerprints were registered and not registered) were involved to show the system was working as we expected. This means that even if the vehicle ignition is in the "ON" position, the motorcycle engine cannot be started using an electric starter method or using a crank start system. To be able to "start" a motorcycle engine, the user's fingerprint must be verified first. In the second phase of the trial, notification via the Blynk application on the smartphone will show someone's fingerprint that started the motorcycle has been verified or not verified. Finally in the final stage of the trial, information systems in the form of notifications on smartphones can be realized to inform users who are trying to start the motorcycle engine have been verified or not verified. The results of this study are expected to become IoT applied references for motorcycle and other vehicle security system
