In this research, the process of applying the K-Nearst Neighbor (KNN) method will be carried out, which is a classification method for a collection of data based on the majority of categories and the goal is to classify new objects based on attributes and sample samples from training data. So that the desired output target is close to the accuracy in conducting learning testing. The results of the test of the K-Nearest Neighbor method. It can be seen that from the K values ??of 1 to 10, the percentage of the results of the analysis of the K-NN method is higher than the results of the analysis of the K-NN method. And from the K value that has been tested, the K 2 value and the K 9 value have the largest percentage so that the accuracy is also more precise. As for the results of testing the K-Nearest Neighbor method in data classification. As for the author's test using a variation of the K value of K-Nearest Neighbor 3,4,5,6,7,8,9. Has a very good percentage of accuracy compared to only K-NN. The test results show the K-Nearest Neighbor method in data classification has a good percentage accuracy when using random data. The percentage of variation in the value of K K-Nearest Neighbor 3,4,5,6,7,8,9 has a percentage of 100%.
Geographic information system is a location mapping information to find out the distance between one area to another. The system to be designed is implemented with computer software and hardware that is used for data verification, data storage, updating and changing data and analyzing data. The system will be designed to search for the location of the nearest school by applying GIS (Geographic Information System) and utilizing an Android smartphone. So far, this is still done manually by using maps in hard copy form or by asking other people directly. However, information about the location of the nearest school is very ineffective when asked to the nearest community. For this reason, it is necessary to have a system designed to find digital-based school locations. The application is designed using android studio and a database used by mysql to store information about schools. The application to be implemented must use an internet connection so that the GPS (Global Positioning System) can run properly.
<p><em>Smartphones with the Android operating system are increasingly available in the market at increasingly affordable prices. The Android operating system itself is an open source operating system that can be modified according to needs. In this research, the aim is to design and implement a home lighting control system that activates and deactivates via a smartphone using Bluetooth and makes Android a multifunctional cellular device, in addition to a communication device but also as a device that is communicated to control a hardware device. Based on the results of tests conducted, the system can work properly in accordance with the goals of the lamp control application program that is made to run on the Android operating system, and can activate and deactivate the lamp driver device. Data communication between the lamp driver device and the Android smartphone runs well, the range of the control application system can control the lamp driver device depending on the specifications of the Bluetooth device used both from the receiver and sender side</em></p><p><em> </em></p><p><strong><em>Keywords :</em></strong><em> Smartphone, Android, Full Control System, Bluetooth</em></p>
Using two methods in decision support according to some circles is very inefficient and redundant (excessive), because in terms of results will be the same. However, according to the author, it is not entirely true, sometimes comparing the two methods is necessary in increasing the confidence of the election (decision). Likewise, if we want to get something, we have to compare from several sources. So basically it will convince the choice (decision). The comparison of the two methods in this study is Simple Additive Weighted (SAW) and Weighting Product (WP) because it uses weight values as the basis of reference. The case told is choosing the quality of shoes based on the brand on the type of sport shoes (sports shoes). The purpose of this research is to determine the best shoe brand, but the main thing is to add value to the confidence of the choice because it has been tested by two methods.
With the design of a car rental service application based on Android, it makes it easier for consumers to make car reservations. Nowadays information media with technology support is needed, especially with Information technology is increasingly modern, the easier it is for each company to exchange information. Technological developments can be felt with more and more website-based services that make it easier for parties companies and customers only connected to a computer network or internet media. In the past, information and communication was carried out Simply put, with the support of this modern information media a lot The company's management system has been supported by a website-based application. The development and construction of a new system can improve the company's performance in the car rental or rental process, namely the new system which is supported and designed specifically for car rental process management. With Android smartphone media, customers don't have to bother coming directly, simply by connecting via a network connection the order can accepted by the company. For employees, it can automatically register because has been supported by computerized database media to present reports and data entry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
