Abstract

One of the criteria in applying mobile navigation is the ability of mobile device to continuously monitor point of access from user, but in monitoring the point or the object always changes due to the movement of user. The changes occurring are known as split nodes. There is a method used to manage split nodes that is KNN search, but the performance is still not satisfactory. Another proposed method is the Voronoi Continuous K Nearest Neighbor (VCKNN) algorithm that uses the Voronoi diagram to help manage split nodes. The use of the VCKNN algorithm is supported by Dijkstra's algorithm in searching for split nodes within the Voronoi polygon. In this research will be done comparison between VCKNN and Dijkstra algorithm in managing split nodes. This is done to get algorithms that have the best performance in managing data on segmentation, runtime and split nodes. This research will take a study area of ​​Malang Raya. Selection of Malang Raya as a study area due to unstructured road network structure neat, so it can know the performance of the proposed algorithm. From this research, the results obtained using VCKNN algorithm occurs the performance improvement compared to Dijkstra's algorithm. Increased performance occurs due to the decrease in the number of split nodes produced. The decrease of split nodes that occur using the VCKNN algorithm based on the use of administrative boundaries sub-district as the interest point resulted in the decrease of split nodes by 92.4%. With the result of this research for Malang Raya road network condition, VCKNN algorithm yield satisfying result.

Abstract

For muslims, understanding Al-Qur'an and Hadis are an obligation because those two is the basic of Islam. In the learning process, a person usually will begin by memorizing the pronounciation and the surah's or hadis's name. After the person can pronounce the surah or hadis fluently, then they will continue to understand the meaning and the content of the surah or hadis. The problem is sometimes a person can forget the name of surah or hadis when another person says a verse from the surah or hadis. So, a solution is needed to handle the problem. In this research, the writer offers a solution to build a system that can identify the name of surah or hadis in Al-Qur'an by taking an input in the form of a sound file with WAV extension using Shazam algorithm. The identification process is done by doing these following actions: numeric value extraction, conversion, feature extraction, filtering and matching. The result is the name and information of the surah or hadis. The best accuracy from identifying surah and hadis from Al-Qur'an is 82% in the testing phase using a test data with 15 second duration, chunk size=4096 and range=60.

Abstract

Power saving consumption is necessary. The power consumption of a house can be monitored through kWh meters. The usual kWh meter monitors the overall power consumption of the house, it doesn't measure the details of the total power consumption of the home. Therefore we need to monitor the system of electric power consumption in every room of the house. Based on that requirement, an electrical power consumption of the outlet system monitoring is available in every room of the house using pervasive computing method. The system is using some devices that is a smartphone application and 2 node devices comprising NodeMCU v1.0 as the microcontroller and the current YHDT SCT-013-020 sensor. The system requires some nodes and an application device to be connected in the same network through the websocket protocol. Device node and the application are communicating through a router. The node device processes the sensor readings and then sends the data to the application. The application will scan the IP subnet mask, if the IP adresses are detected and configured on port 19105, the IP will be identified as node device. Then the application will request the sensor data to the node device and display its data to the user. After the test results are done, it will be known that the system can perform discovery with an average total time of 11156.3 ms, then it will send and display the data via the websocket protocol and the smartphone application.
