Abstract

Technological developments that gave birth to many quality software products. Quality software is software that has gone through testing. In software testing there are several things that must be tested, namely the software must be in accordance with what the user wants or needs, the software must work well when used so that there are no errors, the software must have a good response time when run. Software must be a cost and time efficiency solution. In software testing, one of the methods used is by using the blackbox method. The blackbox method has its own technique, one of which is the equivalence partitioning technique. The equivalence partitioning technique is a technique of dividing several parts or partitions to check each part or partition by testing the software.

Abstract

Data mining using machine learning algorithms can be used to help analyze historical data to predict COVID-19. The dataset used for predicting COVID-19 has many features, but those features have the possibility of redundancy or irrelevance that can cause a decrease in classifier performance. This research proposes a model that implements feature selection to select relevant features and can provide improved performance predictions for diagnose COVID-19. Some proposed feature selection techniques are Sequential Forward Selection (SFS), Sequential Backward Selection (SBS), Sequential Forward Floating Selection (SFFS), Sequential Forward Floating Selection ( SBFS), Sequential Backward Floating Selection (SBFS), and selectKBest. The classification algorithm used to classify is Random Forest. The model that gives the best performance value is the model that applies the SFS dan SFFS as feature selection.

Abstract

In the digital age, mobile applications have become an integral part of everyday life, making usability testing an essential factor in ensuring a seamless user experience. Traditional usability testing methods often demand considerable resources, including time and cost, which calls for more efficient and automated alternatives. This study explores the use of sentiment analysis as an innovative approach to evaluate the usability of mobile applications. By analyzing user reviews from the Google Play Store, the research compares the effectiveness of four machine learning algorithms—Support Vector Machine (SVM), Naive Bayes, Decision Tree, and Random Forest—in classifying sentiment and evaluating usability. A dataset consisting of 2,000 reviews from a banking app was collected and labeled based on usability criteria, such as efficiency, user satisfaction, learnability, memorability, and error rates. The feature extraction process utilized Term Frequency-Inverse Document Frequency (TF-IDF) to enhance the relevance of the review texts for sentiment analysis. The findings reveal that Random Forest achieved the highest accuracy (68.15%) and demonstrated the best performance in terms of F1 Score, precision, and recall, although it had the longest processing time. In contrast, Naive Bayes, while the fastest, showed lower accuracy and F1 Score, making it suitable for applications with large datasets or limited processing time. Decision Tree and SVM offered a balanced trade-off between speed and accuracy. The study concludes that Random Forest is the preferred choice when high accuracy and prediction performance are crucial, despite its longer processing time. Meanwhile, Naive Bayes is more appropriate for scenarios demanding rapid data processing, and SVM and Decision Tree are recommended when a balance between speed and accuracy is needed.

Abstract

The rapid growth of social media usage has significantly influenced the marketing and development strategies of Micro, Small, and Medium Enterprises (MSMEs). However, there remains a limited understanding of how various users perceive the role of social media in supporting MSME growth. This study aims to segment user perceptions regarding the impact of social media on MSMEs, utilizing the K-Means Clustering method. The research novelty lies in combining perceptual analysis with an unsupervised machine learning technique to discover hidden patterns in public responses. Data were collected through a questionnaire distributed to MSME actors and users of MSME products across Indonesia. The questionnaire includes statements related to the accessibility, promotional effectiveness, and trust-building capability of social media. The clustering results categorize respondents into several perception groups—ranging from highly positive to neutral or skeptical, providing valuable insights for stakeholders and digital marketing strategists in targeting communication and support for MSMEs. This approach offers a data-driven strategy to optimize MSME empowerment through the appropriate use of digital platforms.

Abstract

In determining the level of quality of a software it is necessary to test the software. Tests tested can include specifications, design, and coding of the software. This test is conducted to test web-based library software. This test uses the Black Box Testing method using the Equivalence Partitioning technique. Black Box Testing is applied in order to find errors in software related to erroneous functions, errors in interface display, data structure errors or access rights in external databases, sub-optimal performance in a process, and errors in initialization or termination. The Equivalence Partitioning technique defines the cases to be tested by finding some errors and minimizing the number of cases that must be made. The Equivalence Partitioning test case design is based on the premise of the input and output of a component which is partitioned into classes according to the specifications of that component, which are treated equally (equivalence). It can also be assumed that the results of an input produce the same response. The expected result of testing this software is to ensure that this software is free from errors so that in its use there will be no obstacles that prevent the user from doing his work. And inform that the software is in accordance with predetermined specifications.

Abstract

DAPODIKDASMEN (Data Pokok Pendidikan Dasar dan Menengah) is an application that is very important for schools to be used in managing all data related to institutional, curriculum, student data, teacher data, and employee data, as well as data on facilities and infrastructure of all schools in Indonesia and schools- Indonesian schools abroad. This application is quite complex, if something goes wrong can result in large losses. For this reason, testing of features in the DAPODIKDASMEN application is needed to ensure that there are no problems that cause losses, especially for stakeholders (stakeholders), this test is carried out to provide assurance that the DAPODIKDASMEN application is error free and suitable for use. Testing the DAPODIKDASMEN application is proposed by Black Box using the Equivalence Partitions technique so that errors / defects can be identified and can be corrected immediately. The results of testing with the Equivalence Partitions technique can find errors that exist due to errors in the pre-coding stage, as well as unintentional errors in coding, so that the resulting application can be guaranteed to be of high quality and in accordance with established requirements.

Abstract

Rental is a service provider that provides vehicle rental services. Currently, there are still many rental businesses that use manual systems for data processing which results in less efficient and slow work. Lack of information also makes it difficult for prospective tenants to find out the vehicle you want to rent. Making this application design aims to help facilitate ordering and information. This vehicle rental application will be designed using the Unified Modeling Language (UML) method, which visualizes the modeling using Use Case Diagrams and Activity Diagrams. Then the programming language that will be planned is JAVA language, with the MYSQL database as data storage. Meanwhile, the application development uses the Netbeans IDE 8.2. This system will provide results in the form of rental information and ordering transactions to facilitate vehicle rental activities.
