Abstract

PT Jalur Nugraha Ekakurir (JNE) is a shipping service company to various regions in Indonesia and overseas. JNE is one of the options for sending goods in e-commerce. PT JNE has a mobile application that has features such as tracking items, checking rates, and a variety of other features. Based on observations and responses found in the Play Store, usability problems was found in the MY JNE application that had an impact on poor user experience. A new design recommendation can be proposed to reduce such problems. This study combines the UEQ (User Experience Questionnaire) method to obtain quantitative user experience from users and Heuristic Evaluation to obtain qualitative evaluations from evaluators. The first step is to find the level of user experience from the UEQ method and then continue with the Heuristic Evaluation to the evaluator on finding more problems. The next step is analyzing the results obtained and then draw conclusions by making design improvements. There were 30 individuals who participated in this study who were selected based on several criteria which are currently staying in Malang and own a MY JNE account. The UEQ benchmark measurement results in the Bad category for Attractiveness, Efficiency, Dependability, Stimulation, and Novelty. However, for the Perspicuity scale, it produces a Below Average category. The evaluator found 22 usability issues and suggested design improvements for the future. Consolidation has been carried out and followed by designing prototypes from evaluator recommendations. The prototype design that was built was based on 10 principles of usability Nielsen and Google Material Design. The results of testing the prototype have completed 22 previous usability problems and found a new problem with a minor severity ratings value.

Abstract

The use of e-books on the development of digital technology makes it easy for users to get more practical information than having to use printed books. The number of e-books spread on the internet is very numerous and varied, therefore a system for retrieving information on e-book documents in Indonesian is needed. To improve the relevance of the results of the returned documents, relevance feedback techniques can be applied. Relevance feedback is a technique where users can provide feedback on previous document search results. Sorting the number of documents returned based on queries is calculated using the BM25 method. This study aims to determine the results of the application and the results of testing of relevance feedback on the retrieval system of Indonesian e-book document information using the BM25 method. Based on the test results, the AVP value after relevance feedback has decreased. In testing based on K values, the AVP value before RF is 0.592, after RF(20) is 0,558, and after RF(50) is 0.573. While in testing based on the expansion terms, the AVP value before RF is 0.593, after RF(20) is 0,587 and after RF(50) is 0.570.

Abstract

Emotion shapes human behavior in general and very important in life. Detecting emotions provides an important role in various aspects because it can be applied in various fields such as decision-making, predicting human emotions conditions, providing a review product quality, tracking support for political problems, and recognizing depression disorders. Identifying emotions can use textual data that is text, text can be used to communicate and declare information. The social media that used to exchange information is Twitter. Twitter contains information about human attitude and human emotions. Therefore, emotional detection is needed to determine human emotions using Naive Bayes method and feature combinations. This research using several Naive Bayes classification models namely Bernoulli Naive Bayes for binary data types and Multinomial Naive Bayes for discrete data types. Feature Combination used in this research is as follows: linguistic features, orthographic features, and N-gram feature combinations. The best accuracy result obtained a value of 0.555 that is in testing N-gram feature combinations. While the combination of features including linguistic features, orthographic features, and N-gram features produced an accuracy value of 0.5317 which means this value was better than testing with a single feature and lower than testing the N-gram feature combinations. This is due to the influence of linguistic features, orthographic features, and N-gram features. Based on these results it can be concluded that by using combination features can cover the weaknesses of each feature that can improve the performance of accuracy even though the increase is not too significant.

Abstract

MANET is a wireless architecture network consisting of several mobile devices. It doesn't need any infrastructure or central access point like base station. MANET has 3 types of protocols, namely reactive routing protocol, proactive routing protocol, and hybrid routing protocol. AODV is an example of reactive routing protocol. MANET is still vulnerable to various forms of attacks which are capable to modify, harm, and delete the information data. One of the attacks that can occur in MANET is wormhole attack. Wormhole attack is an attack involving two or more attacking nodes connected in a tunnel, and manipulate the routing and also is able to do packet drop and selective packet drop. Testing is done with OMNET++ network simulator with a various scenarios like number of nodes, number of attacker nodes, and mobility nodes. Testing parameters includes end-to-end delay mean, throughput, packet delivery ratio (PDR), and packet loss. The results show that lowest value of PDR is 27.4% in 10 node with 2 attacker using gauss markov mobility scenario. The lowest value of packet loss is 46 from 2000 sent packet from source node in 30 node with 0 attacker using random waypoint mobility. The lowest mean of end-to-end delay is 8.5ms in 30 node with 4 attacker using random waypoint mobility.

Abstract

Dinas Komunikasi dan Informatika (Dinas Kominfo) Kabupaten Lumajang is one of the government agencies that is tasked with serving the community in the field of information and communication. Some of the services managed by the Dinas Kominfo include intranet development services and the use of internet access, data center infrastructure services, e-Govenment data and information management services, e-Government information security services, and integration of government public services. To manage these services needed adequate human resources (HR) for the implementation of operational activities properly. Based on the results of interviews, it is known that the condition of human resources at the Dinas Kominfo is still lacking which causes an overwork with the many operational activities related to information technology at Diskominfo. Therefore an evaluation is needed to determine the current condition of HR management and operational management processes at Diskominfo so that recommendations can be given on existing problems. The evaluation is based on the COBIT 5 framework of APO07 (Manage Human Resource) and DSS01 (Manage Operations) processes. Data were collected by several methods, namely interviews, questionnaires, and observations. The assessment is carried out in stages starting from level 0 to level 5 to determine the level of capability. Capability level obtained in each process is level 1 with a gap of 1 from the target level. Recommendations that can be given for the APO07 process are 10 points and for DSS01 are 6 points.
