Abstract

Emergency Reporting Application is an android-based application that serves to help the community in reporting the emergency condition. This application allows users to choose and contact the emergency services office, without the need to notice their position and phone number. Selection of emergency services office is also automatically selected by the system by taking into account the distance between the complainant and the emergency services office. The selected emergency services office is the nearest emergency service office from the complainant so that the delay in coming assistance can be minimized. Therefore, this proposed application requires a GPS feature to recording, reporting and SMS positioning for message delivery of reports. The distance between the position of the complainant and the position of the emergency service office, in the form of latitude and longitude data, is requested using the Haversine formula taking into account the degree of curvature of the earth. Emergency service offices include police and hospital offices spread over 25 different districts. Furthermore, the reporters position calculation results were compared with all selected emergency service offices and obtained 1 nearest emergency service office. Calculating the accuracy and delay value of the system will do system testing. Accuracy test results using the method of 100% Haversine and the average delay of the system is 4.5 seconds.

Abstract

HAPS (High Altitude Platform Station), the infrastructure that is made to change BTS/BS, it could be one of solution to reduce cost and capacity problem. HAPS is like airship or aircraft that is placed on stratosphere line, the distance of platform is 17-22 km from earth surface. Because of that position, it’s affected by wind gusting, so that HAPS’s position can change from normal state that is called Platform Displacement. This research explain about the impacted of platform displacement to mobile station (MS) during HO process which is measured delay HO value. User is mobile wimax user who is doing communication using VoIP. Platform will be simulated in some position, horizontal position and vertical position, than MS moves on some speed, first, in medium speed is 50 Km/hour and 80 Km/hour, second high speed is 120 km/hour dan 200 km/hour. When platfor moves to the higher position will increase the coverage of cells, so each cell will interfere their neighbor. The effect of changing it position is perceived by user in transition area, this condition can disturb the HO process.

Abstract

HAPS (High Altitude Platform Station) is an airship or aircraft positioned 17-22 km altitude, or in stratosphere. HAPS is the development infrastructure of telecommunication network as BTS/BS replacement. BTS / BS is seen still has shortcomings in funding and capacity range. HAPS position is on the air layer will effected by wind disgusting so that position of HAPS will change form its normal state called Platform Displacement. Therefore, in this research, we will discuss the impact of HAPS displacement on the quality of service perceived MS (Mobile Station) by measuring the throughput. Throughput values will be mesured during MS is doing handover (HO) process, user is a mobile user who is doing WiMAX VoIP communications. Users will be simulated moves with constant speed of 50 km / h, 80 km / h, 120km / h and 200 km / h. Platform will simulated in some position upward, downward, to the right and to the left. When platform moves upward, cells will increase the coverage so each cell will interfere their neighbor especially when MS is doing HO process

Abstract

Spider robot is controlled using ATMega32 microcontroller and programmed using C language on CV AVR Software. This robot is designed to help people in the fire fighting in the fire accident. This robot has 3 ultrasonic PING sensors that are placed on the front, right and left as a distance detector to regulate the movement of the robot and a flame detector sensor that is placed on the front as a fire detector. Robot also has 2 work modes that are manual mode and automatic mode. Manual mode is a mode where the movement of the robot is ordered to use the remote bluetooth with 7 meters of maximum distance, while the automatic mode is the mode where the movement of the robot fully using PING ultrasonic sensors. From the results of fire detection testing, the robot is able to detect the presence of fire less than 20 cm, in that position the robot will stop and turn on the fan automatically. Furthermore, from the results of robot movement testing, the robot detects the presence of obstacle as far as 20 cm, in that position the robot will stop and it will read the ultrasonic sensor PING on the right and left to decide the next movement.

Abstract

Documentation of students' final project (TGA) books is very important for mapping research and minimizing plagiarism. In some cases, many TGA books have not been recorded correctly, so the library administration team at both the institutional and departmental levels must re-register it with a manual system so that this activity can spend not enough time. For this reason, this study aims to build a system that can help the documentation process quickly and easily. The system is a software based on digital image processing. The cover image of the TGA book is taken using a webcam and then processed by preprocessing, binerization, segmentation and character recognition. The result of the research is book title by text format. The methods to be used in this research include the acquisition process using specific box, Otsu Thresholding, segmentation, and pattern recognition using the Correlation Coefficient method. From the results of the research that has been done, it is found that the overall success rate of the system in recognizing the image patterns of letters in student TGA books is 95%.

Abstract

Abstract Security is an important thing to pay attention to and to create that security, there are many things we can do, the most obvious common thing we do, for example to guard a house is to hire a security guard / house keeper. But to hire a house guard requires a fairly expensive cost. With the development of electronic technology, the security system is increasingly sophisticated and growing, so far there has often been theft or burglary from this house where a security door building system has been developed using fingerprint and Android as a controller. For this security door method using finger print and android as a door opener or controller. In this equipment, only the fingerprints that are registered on the finger print can access the door to open, and Android functions as a notification whether the door has been opened or not. Operationally, this security door system works well and is regulated by a microcontroller, and this system works well, with the data that we tested that this security door is 100% safe using the finger print method with the data we tested. Keywords: Fingerprint, Security, android, microcontroller, controller __________________________ Abstrak Keamanan merupakan suatu hal penting untuk diperhatikan dan untuk menciptakan keamaan itu banyak hal yang bisa kita lakukan, hal umum paling nyata yang kita lakukan misalnya untuk menjaga rumah ialah menyewa satpam/penjaga rumah. Tetapi untuk menyewa penjaga rumah memerlukan biaya yang lumayan mahal. Dengan berkembangnya teknologi elektronik, maka sistem keamanan semakin canggih dan berkembang, selama ini sering terjadi pencurian ataupun pembobolan rumah dari sinilah dikembangkan sistem bangun pengaman pintu menggunakan fingerprint dan android sebagai pengontrol. Untuk metode pintu keamanan ini menggunakan finger print dan android sebagai pembuka atau pengontrol pintu. Dalam peralatan ini hanya sidik jari yang terdaftar pada finger print yang bisa mengakses pintu untuk terbuka dan android berfungsi untuk sebagai pemberitahuan status pintu telah dibuka ataupun belum. Secara oprasional sistem pintu keamanan ini bekerja dengan baik dan diatur oleh mikrokontroler,dan sistem ini bekerja dengan baik, dengan data yang kami ujicoba yaitu pintu keamaan ini 100 % aman dengan menggunakan metode finger print dengan data yang kami uji.
