Abstract

Long Range Wide Area Network (LoRaWAN) is a type of network for wireless telecommunication area designed to enable remote communication with long distance communication and low bit rate. LoRaWAN can be used on communication networks that have a wide range using end devices. LoRaWAN offers a wide range of advantages to the challenge of IoT implementation, but the current implementation of LoRaWAN technology is still very limited, requiring feasibility testing and analysis to what extent LoRaWAN technology is capable of being implemented in urban areas in Indonesia. In this research, an analysis of the performance of the LoRaWAN protocol for data transmission with urban area scenarios in Malang City is carried out. The method used in this study is to simulates LoRaWAN protocol in Network Simulator 3 (NS-3) application by changing the parameters to determine the effect on the the number of end devices, radius of the gateway range, and data sending period to the parameters throughput and packet loss. From the results of research proved that for the use of protocol LoRaWAN in urban areas, the more end devices used, the greater the throughput value and the greater the value of packet loss obtained. In addition, the wider the area needed, the throughput and packet loss obtained are constant. And then, the larger the period of data transmission, the smaller the throughput value is obtained and the smaller the value of packet loss obtained.

Abstract

Routing is the process of determining the path to convey data from source to destination. In conventional network routing configuration is still not flexible and efficient, because they have to configure network devices manually. Software-Defined Network as a new paradigm in network architecture, has the flexibility and efficiency for centralized network configuration. In SDN, the data plane and control plane are connected by the OpenFlow protocol. Routing on the network can be interrupted because of link disruptions such as link failures that result in the system having to find another pathway to keep communicating. In this research, network routing uses DFS and BFS algorithms, because both has simple concept and better complexity than other routing algorithms such as Dijkstra. The testing parameters are path finding, response time, packet loss, and packet traffic. When at link failure, system can still find another path to continue sending data from the source node to the destination node. The results of response time without link failure, both algorithms have been able to search for the best path based on determining the maximum value of the path on the controller. The average value of packet loss when 1 link down on DFS has the same result as BFS when 2 links down, which is 3.62%. In traffic testing, both algorithms have the same average value of the results of packet transmission to another switch, which is 52.67%.

Abstract

Every year,Quail can producing eggs from 240 until 300 grain each head. With their small body, the result of their egg's production are high enough. For breeder raising quail is a good opportunity to make a profit with the many demands nowadays. The method that used by breeder to improve the quality of quails is to separate the cage according to the age of the quails. Separating cages is also useful for distinguishing feed, and quail's nutrition that needed. In this study, we will use body weight as a parameter to classify the status of quail growth, which in general farmers use age as a parameter to separate cages. Loadcell weight sensors will be used as a medium to measure bird weight. Then Arduino will be used as a microcontroller and LCD to display the results. In classifying quail based in body weight, it requires a method to calculate them. Method that used in this study is the K-nearest neighbor(KNN) method. This system will test several asppects of the system including sensor accuracy, comparison between age and weight classification, and system computation time. For the accuracy of the sensor we got the result of accuracy 96.67%. Then in testing using KNN based on body weight compared to age, get the result of an error of 2.23%. And for testing computation time, obtained an average time of 612ms.

Abstract

Cervical cancer is the second most common cancer in Indonesia after breast cancer. The number of deaths from cervical cancer in Indonesia continues to increase every year due to delays in making diagnoses and examinations. To detect cervical cancer, a laboratory examination using Visual Inspection with Acetic Acid (IVA) or pap smears is needed which requires specialist internal medicine and several considerations of features to get accurate diagnosis. Sometimes, how to analyze features by doctor with one another produces different results. Therefore, a classification process is needed to make a diagnosis of cervical cancer with high accuracy results so that it is expected to be able to match the diagnosis results of medical personnel. This study uses cervical cancer risk classification data with feature selection based on expert interviews. This study uses the Extreme Learning Machine algorithm to carry out the classification process and measure the results of algorithm performance with accuracy values ​​from the calculation of confusion matrix. Based on the test results obtained the optimal parameters are as many as 11 hidden neurons, the activation function is binary sigmoid, and the fold on training and testing data is fold 1st which produces an accuracy of 91.76%.

Abstract

A rapidly increasing demand of game content is the main reason which induced the urgency for a straightforward method for generating new level content that goes hand in hand with the automated technology field. A labyrin based level requires a certain uniqueness without the risk of encumbering the development process in time or budget. With that in mind, the author raises this thesis that proposes the use Binary Tree Algorithm to implement Procedural Content Generation to generate levels in a maze game genre. This algorithm will carve a maze path from two pre-determined directions, this implementation can result in a fast and simple generation. The result of this paper shows an average of 0.435 second to generate three levels with different sizes. The resulting levels are all valid and playable according to the labyrin parameters such as a valid starting and ending point, a path between these two points, and a labyrin that follows the set grid. This algorithm also has a bias for diagonal paths, and a long corridor is usually formed on two sides of the generated maze. The conclusion is that Binary Tree Algorithm is perfectly suitable as a maze level generator in a hexagonal grid with fast generating time and a reliable generated level.
