Abstract

The quality of the interface in the Geographic Information System (GIS) was still not a major concern, whereas the quality of the interface was the prominent impact on the use of the Geographic Information System and some problems in the interface design contained in the Geographic Information System application were inconvenient to grasp by the user when is compared to the technical problems. This study aims to evaluate the interface of Geographic Information System processing applications (QGIS and MapWindow) so it known that the most optimal interface design could be identified by using the Heuristic Evaluation (HE) method to the function of geoprocessing tools. Based on the evaluation, QGIS application problems in the category "H1 - Visibility of system" and MapWindow application problems in the category "H7 - Flexibility and efficiency of use" were the particular concern for the evaluators. Besides, if the both applications were compared, the earlier evaluation showed QGIS application has 23 problems with an average severity rating is 2.0, this amount was higher compared to MapWindow application which only has 21 problems with an average severity rating is 1.9. However, in the final evaluation showed the different results, QGIS application only has 71 problems with an average severity rating is 2.02, this amount was lower than MapWindow application because the MapWindow application has 73 problems with an average of severity rating is 2.08.

Abstract

The IoT data storage system in general is centralized so that the data generated by the IoT sensor are stored on one data storage only. Centralized systems are susceptible to failure, which can cause the entire system to crash and can cause data loss because there are no backups. Therefore, in this study, we will propose a decentralized storage system using blockchain. The Blockchain is a decentralized, distributed, and immutable database that stores assets and lists of transactions in peer-to-peer (blockchain) networks. The Blockchain can replicate data to be stored on many nodes in the blockchain network. If there is a system failure on one node, the node will not affect the system on the other node. This research focuses on implementing blockchain on IoT data storage systems using BigchainDB and Tendermint. BigchainDB and Tendermint are the right applications to implement blockchain on MongoDB-based IoT data storage systems. The results of functional testing show that the decentralized IoT data storage system is running by its function in storing data and replicating data on several data storage areas. Based on these results, the system in this study can be a solution for centralized IoT data storage systems.

Abstract

Today, social media has become a new lifestyle for modern society. One of the most popular social media is Twitter. The character limitation when tweeting on Twitter makes the message conveyed by its users short, solid and clear. Thus, the complaints of users as outlined in a tweet can be analyzed using text classification which can then be used as a new method to determine the stress level of a person. In which up to this time, to determine the stress level is still done manually using a questionnaire system. The text classification used in this study is the Improved k-Nearest Neighbor method which is an improvisation of the k-Nearest Neighbor method which has a weakness in the use of k values for all classes. In addition, to improve the accuracy of the system and eliminate less relevant features, chi-square feature selection is used which can eliminate less relevant features without reducing the accuracy of the system. From 5 feature ratio tests, the best value is obtained at the feature ratio of 25% and k-value = 20 with an average precision value of 70%, the average recall is 67.2%, the average accuracy is 83.3%, and the average f-measure is 66.3%. From this research, it can be concluded that feature selection can increase the average precision, recall, accuracy, and f-measure.

Abstract

Music consists of various genres and emotions, therefore it is important to group the music according to what the listener wants both based on the genre and the emotions they feel. As an example of an online music application that can automatically group music that makes it easy for listeners to play the desired music, music grouping is seen based on the similarity of certain characteristics. Another example is the Radio music player, where a common problem with radio broadcasters is to play and choose what songs to play. With the grouping of music automatically this will certainly be very helpful and more efficient for playing these songs automatically. Then this research will cluster songs based on the emotions of Broken Heart and Happy with feature extraction using the Haar Wavelet transformation method, then clustering using K-Means. The results of clustering will be evaluated using purity. The test is based on the song structure, a combination of statistical features, and the Haar Wavelet coefficient. Based on the results of all tests carried out obtained clustering with the highest purity value of 0.62.
