Abstract

Mobile app of Info BMKG is a government application that provides an early warning, earthquake, weather, climate, and etc according to its scope. Based on the observations, interviews, and several responses in the Playstore comment column, various problem were found on the application that could make the user experience worse. To reduce any issues related to user experience, therefore an evalation is required to improve its user interface. This research is conducted with the UEQ (User Experience Questionnaire) method to measure the quality of the user experience level and HE (Heuristic Evaluation) to specify a problem(s) for the evaluator. The first evaluation is found that the BMKG app has a neutral user experience level and ”bad” rank resulted from the UEQ benchmark in 4 scales which are Attractiveness, Perspicuity, Efficiency, and Novelty and acquired a ”below average” category in 2 scales which are Dependability and Stimulation. Besides that, as much as 17 issues have been discovered by the evaluator and a list of design fix recommendations have been provided. The design fixes are then re-measured where it is discovered that there is a significant rise in the user experience level that results in a positive level and the UEQ benchmark category for Attractiveness, Efficiency, Dependability, Stimulation and Novelty is raised to a ”good” category, while the Perspicuity scale is measured in the ”above” category.

Abstract

The functional position of the lecturer is the position of the lecturer based on the , responsibilities, duties, rights and authority in Higher Education based on certain expertise and individual nature. While rank is a position that shows the level of an employee based on his position in a series of staffing and is used as a base for payroll. In the Faculty of Computer Science, Universitas Brawijaya (FILKOM) from the field findings of several FILKOM lecturers that the lecturer had many activities. Then when the file validation and verification process in the FILKOM employee proposed a frequent error so that it did not have time to process further revisions in collecting files in 4 fields and administrative files for proposed promotions and / or functional positions. Coupled with the lecturer still doing the AK calculation manually by looking at the guide so that it allows even fatal calculation errors can be mistaken in the calculation of AK in each activity. In this study aims to help FILKOM lecturers in collecting 4 fields of files, assisting in the validation and verification of 4 fields of files, monitoring the status of proposals, and also assisting lecturers in calculating AK lecturers' activities automatically based on AK assessment guidelines. In this study using a prototyping approach. And in its implementation, it applies dummy webservice to retrieve BKD file data, Universitas Brawijaya staff and lecturers, especially FILKOM. The results of this study were obtained twenty-eight functional requirements and one non-functional requirement obtained from 1 prototyping iteration process. From the results of unit testing, integration and compatibility testing of the browser environment, the results are 100% valid.

Abstract

Hate speech is a form of expression that is done to eliminate hatred and commit acts of violence and oppose someone or a group of people for various reasons. The cases of hate speech are very often encountered on social media, one of which is on Twitter. The goal to be achieved is to create a system that can classify a tweet on Twitter into a class of hate speech (HS) or non hate speech (NONHS). The method used is Naive Bayes and Information Gain feature selection with word normalization. Word normalization is used to solve problems on Twitter such as the number of words abbreviated, the use of slang, misspellings, and the use of languages ​​that are not in accordance with existing standards.Word normalization comes from Indonesian Natural Language Processing REST API. The data used supports 250 data tweets of hate speech in Indonesian with a ratio of 80% for training data and 20% for testing data. The threshold used is 20%, 40%, 60%, 80%, and 90%. Threshold is a limit that is determined to store a collection of terms or a collection of words with the aim of selecting a word that has a high value ​​in the Information Gain feature selection. The best accuracy results obtained by using word normalization in the pre-processing stage and using Information Gain feature selection with an 80% threshold. The best accuracy result is 98%, precision result is 100%, recall result is 96.15%, and f-measure result is 98.03%. Based on the analysis of the results and testing obtained, it can be concluded when doing hate speech classifications in Indonesian on Twitter using Naive Bayes and Information Gain feature selection with word normalization can improve better accuracy of the results.

Abstract

Software maintenance is a software development phase that requires more effort, time, and cost. One of the causes of maintenance problems is the high value of software complexity. Developers will find it difficult to understand the software when doing maintenance or if there are changes. In the Object Oriented approach (OO) the use of inheritance, encapsulation, coupling, polymorphism, etc. can facilitate developers in building software. However, the use of high inheritance can also result in high values ​​of complexity. Manually calculating the complexity of a lot of software requires a lot of time and resources. Therefore, it is easy to help calculating software complexity using the Cognitive Weighted Inherited Class Complexity (CWICC) ​​metric. CWICC metrics are OO metrics that function to calculate the complexity of software based on an understanding of the attributes, methods, and inheritance of a class. This system has been built on the programming language of Java and also has been tested using unit testing and integration testing that uses whitebox testing and validations testing that use blackbox testing. This system has an accuracy of 100% and the time for calculating with system is 356 times more faster than with manually.

Abstract

The scarcity of subsidized LPG is become the biggest problem for the people in lower to middle class. This scarcity triggered by the increasing of the community that used LPG. In addition, scarcity had been caused by a fraud of some people whose shouldn't use a subsidized LPG. For the some people whose the cattle breeders in Claket Village isn't unfortunate this problem, because they are recycling cow manures become to a biogas. Than, the product of biogas can be alleviate for the breeders themselves and for the neighbours if they needed. However, there's nothing cost controller had been used to control the user for using biogas, so they needed a tool that can be used to control a biogas payment. Therefore, the solution was offered by make a web-based biogas payment system by applying the internet of things concept. The internet of things concept is built with the NodeMCU based module and it's working in MQTT network protocol as a bridge of data communication. This device will be used to detect a biogas flows and converting into data. Furthermore, it will be send and process into biogas payment system. Finally, several stages of testing are carried out on the system which results in a valid percentage of 100%.
