Abstract

Autonomous Mobile Robot is rife in many researches especially the Maze Wall Follower robot that can find its way out of a very complicated labyrinth. In this study the Robot Maze Wall Follower using Backtracking algorithm is to trace all possible paths in the maze and recognize each node that is passed so as not to repeat the path that has been passed. This prototype is built using several modules of Arduino Nano as its processing, Ultrasonic sensor, Photodiode sensor and L298N Driver Motor. Test results from measurement of wall distance using HC SR04 Ultrasonic sensor which is tested as much as 4 times with different distance obtained by the distance of sensor distance to wall the smaller also the level of accuracy of sensor, line reading done with 3 different color and every color is done 3 times the test result is just a black color that can't reflect light that can be read by the photodiode sensor. Testing the robot control system, the left turn of success reaches 50% at the right turn reaches 70% and when the turnaround only reaches 40%. After mapping the maze using the Backtracking algorithm all paths that have been passed by the robot will be marked, after all the lines have been robot so the robot will stop moving.

Abstract

Wireless Sensor Network is one of the many technologies currently used in various fields. But in fact to be able to make a WSN system can work requires a lot of time, experience and also sufficient knowledge. It is difficult to configure a node to work properly. In order for the sensor node can be used alone the process to be traversed quite complicated, starting from the arrangement of the circuit, wiring, programming and others. Solution to this problem is by applying a Modular WSN system where part of the node is separated into specific modules by type and usability, the module type is divided into core module (controller device), communication module and sensor module. In the existing module itself applied Plug and Play system so that each module can be directly used without having to go through any configuration process. In this study only focuses on the sensor module where the sensor module consists of several different types of sensors. The sensor modules that the PnP system has implemented can be directly used when connected to the controller. The process of detection and identification process is done by utilizing serial communication I2C (Inter Integrated Circuit). From the results of several tests conducted known that the process of detection, data transmission and also the selection of active modules successfully done without experiencing any constraints.

Abstract

There are 2 (two) types of routing, static routing and dynamic routing. Static routing is a type of routing that will done manually, while dynamic routing is a type of routing that is more automatic routing. One of network architecture that implements dynamic routing at this time is SDN, in the routing process there are several problems, one of that problem is link failure, where failure on a path can affect data sending process in the network. At this time there are many types of routing algorithms such as Dijkstra's Algorithm, Dijkstra's algorithm way to finding the shortest path by checking each path until it produces the best path. While Floyd-Warshall is more dynamic algorithm in searching for the shortest path not just fixed on the lowest cost value, but also considering the future consequences of each step that will be taken. To know about performance comparison the researcher made a comparison on the re-routing process using the Djikstra and Floyd-Warshall algorithms to find out which ones were faster in overcoming the link failure at SDN. From the comparison of the Djikstra and Floyd-Warshall algorithm's convergence time, Dijkstra's algorithm has better results i.e for scenario 1 0ms, scenario 2 16.401ms, and scenario 3 17.200ms compared to Floyd-Warshall algorithm, for scenario 1 0ms, scenario 2 19.803 ms, and scenario 3 20.401ms.

Abstract

Internet of Things (IoT) is the machine-to-machine or machine to application communication concept which has the vision that billion of sensors, actuators, and many daily devices could be connected to the internet. Message Queue Telemetry Transport (MQTT) is one of the protocol included in Internet of Things which is useful to save power and reduce the size of packet data messaging. Therefore, it is important to study the ability of modern IoT systems to handle high rates of data updates coming from devices. The upcoming thing in the future is about storage media to handle the IoT data, such as a database system to store the data. A flexible database which could handle the data from the IoT device is required. The writer in this work will evaluated the performance of Not Only SQL (NoSQL) MongoDB Database towards MQTT Protocol. In this work, writer use the parameter for the performance testing is the Load Testing. The process practice for the MQTT Protocol as a sensor data transmission media uses NodeMCU microcontroller with the publish and subscribe method. Load Testing method was choosen as a technique to test the relation between the execution time of MongoDB to store the data of the sensor from MQTT protocol. From this work, claimed that NodeMCU could be configurated with MQTT Protocol, with a 75% accuracy of success for connection within the range from 4 meter to 20 meter. From this work we also got that the execution time for MongoDB to store 50 to 1500 data without the database being configured is less than 0.5 Second, and the execution time for MongoDB to store 50 to 1500 data if the database was already set needs less than 0.2 second to store.

Abstract

One of the process that can be implemented in text mining is categorizing text documents. Problems that related the categorizing text documents are found in universities, especially in the reading room of the Faculty of Computer Science, Universitas Brawijaya (FILKOM UB). There is no process for categorizing thesis documents automatically is one of the problem. The thesis documents categorization in FILKOM UB's reading room is still not organized according to the focus of the existing research. The categorization is completed using the BM25 and K-Nearest Neighbor methods. The process was done is pre-processing text document, calculate the BM25 score of each document, then classify them using the K-Nearest Neighbor algorithm. The testing process in this research uses 10 k-fold. Each test used 31 testing documents and 300 training documents. The average results obtained in each test produced the best results at the value of k=11 with a f-measure value is 0.9092, recall is 0.9087, and precision is 0.9265. The greater the value of k cause the classification process runs less optimally because it produces a smaller f-measure value.
