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

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%.
