Abstract

Various objects in the form of digital images can be extracted the features. One of the features that can be used in feature extraction is statistical texture features. In this case, the feature extraction is used to identify the characteristics of each type of facial skin because many cases of mistakenly recognize the type of facial skin that has resulted in occurrence of diseases and unwanted things on the face. In this study, the author uses facial skin especially the cheek part as the object of research because the cheek is one part of the T-zone. Local Binary Pattern (LBP) is one of the feature extraction method that uses adjacency/neighboring distance and the number of neighbors that can be used and utilized in the identification process, which can be combined with statistical texture features. The benefit of this study itself is to assist in the initial diagnosis in determining the type of facial skin that is owned. This study uses data as many as 112 female face images obtained by taking data directly in the field (primary data). This study got the highest accuracy result that was equal to 84.62% with adjacency/neighboring distance (R) = 1 and a combination of 3 statistical texture features, that is a combination of mean, skewness and energy.

Abstract

In developing or changing a software, it is necessary to observe the maintainability so that the software does not have low maintainability. Low maintainability can make the software difficult to understand, expensive to repair and develop or change in the future. One of the causes of low maintainability is code smell. Not all developers have enough knowledge about code smell, even though they understand about it, it is uncertain if they can necessarily find a solution that must be taken to overcome the code smell or not. The long method smell detection system has a feature to help developers detect it, and effective methods and refactoring methods that can be done from java source code so that it can reduce the effort of developers to overcome code smell, especially long methods. This system developed based on Refactoring Filtering Metrics (RFM), which calculates switch, edge, node, def, c-use, p-use and complexity of condition values. The RFM value used as the basis for detecting the long method smell using Refactoring Filtering Condition. This system has been tested by the Whitebox method and validation testing using the Blackbox method. This system can operate detection in less than 10 seconds and has a detection accuracy of 100 percent.

Abstract

Content Centric Networking (CCN) is a proposed architecture for addressing current Internet issues in terms of data distribution. The CCN is content-centric based, where the data search is performed using the name of the content, not the content host. CCN also has a different caching mechanism than caching in general called in-network caching. This study aims to find out how the performance of in-network caching on CCN by design and implementation using CCN-Lite in OMNeT ++ environment. The parameters tested were delivery latency and cache hit ratio (CHR). The result of the simulation is done, the smallest delivery latency is 10.69 ms. This value is obtained from the caching process, when compared with the latency of delivery without caching that is equal to 32.45 ms. It proves that with the caching, the latency gets lower. The highest CHR obtained in the CCNTLV protocol file is 0.54 or 54%, when compared with the CCNB file protocol of 0.45 or 45%. This proves that the higher the value of CHR the better the content is served.

Abstract

Internet users are increasing, causing access demands to a service to increase, which results in the possibility of overloading the server as well. This problem can solve with load balancing technology. The development of network architecture now leads to the Software Defined Network (SDN) because SDN is a architecture that is manageable, dynamic, cost-effective, and adaptable. Previous research has applied load balancing technology on SDN networks using the weighted least-connection algorithm. However, the research still uses flow, which has expired time. In other studies that use the least connection algorithm (LCA) have overcome the problem of expired flow using psutil agents. But the results of the study showed very high CPU usage and unstable traffic distribution. Therefore, this study will apply the psutil agent-based method to the Load Balancing system on SDN networks using the weighted least connection (WLCA) algorithm and determine the performance of the agent-based method. The functional test results show that the psutil agent can send the value of the information on the number of connections on the server to the controller with an error value of 0%. The application of the psutil agent to the weighted least connection algorithm is also better. In testing 500 requests, the response time of WLCA was 29ms while at LCA was 33ms, the value of memory utilization in WLCA was 20.9% while LCA was 21% and the value of CPU utilization in WLCA was 81.2% while at LCA is 84.3%. On the other side, on the 300 and 500 request tests, WLCA algorithm traffic distribution is more stable compared to the LCA algorithm.

Abstract

Jawa Timur Park 1 is a tourist attraction located in the tourist town of Batu with an area of 8 hectares. For some people who have just visited Jawa Timur Park 1 for the first time, most will find it difficult to travel from one place to another in Jawa Timur Park 1 which can be rides or public places. The currently available solution today is by spreading maps of Jawa Timur Park 1 in several locations in Jawa Timur Park 1. However, the use of conventional maps is considered to be susceptible to causing errors in reading directions. In this research, a navigation application that is able to overcome this problem will be developed so that users can travel from one place to another more efficiently. The application will implement augmented reality technology with the help of ARCore SDK so that it allows users to understand the given directions more effectively and able to provide a different experience in navigating. The results of validation testing using the black box method produce a suitability value of 100% which indicates that all functions in the application can run as expected. Then the use of the application is considered capable of increasing the level of efficiency in terms of navigating time by 44,6%. While on usability testing related to the user satisfaction level, the application gets a value of 79,69 which indicate that the developed application is able to provide a good level of satisfaction to the user regarding the use of the application.
