As the digital landscape continues to evolve through the widespread use of software, understanding how users interact with software becomes increasingly important. This article presents the findings of a literature review that explores the use of Electroencephalography (EEG) signals to assess user interfaces, user experience, and/or software usability. We used the mapping review method in this research with the main stages including: 1) Establishing research questions; 2) Source selection; 3) Identifying keywords; 4) Carrying out a screening process; and 5) Extracting and synthesizing data. As a result, we determined 16 relevant papers as primary sources. We highlight the distribution of papers from various databases and their suitability for the period January 2013 to May 2023. In addition, we find that traditional EEG devices, standard five frequency bands, 32 electrodes, signal classification techniques such as Linear Discriminant Analysis (LDA), Frequency Fourier Transform (FFT), and Power Spectrum Density (PSD), gaming software as research subjects, and user experience evaluation questionnaires are most widely used in research practice. The results of this literature review provide comprehensive insight into the latest developments in the use of EEG signals to evaluate software in terms of the field of Human-Computer Interaction, to reduce the factors of subjectivity, bias, efficiency, and accuracy of evaluation results. These insights can serve as a basis for further research and the development of more effective methods and tools for improving software quality.

This research investigates the use of traditional musical instruments based on Virtual Reality (VR) with leap motion control. This technology enables users to virtually interact with Panting instruments and aims to explore immersive user experiences, challenges, and cultural preservation. We collected data through a questionnaire consisting of both open and closed questions, and analyzed the data using descriptive statistics and textual analysis. We can confirm that the proposed modern technology has the potential to promote and preserve traditional Panting musical instruments, especially for the younger generation, but alignment with cultural values and holistic education needs to be considered. In conclusion, VR technology with leap motion control promises to preserve Panting's music, but overcoming technical and cultural challenges is critical to long-term success.

Research interest in the application of Computer Vision (CV) in the context of smart cities has grown significantly in recent years. However, finding relevant studies in databases can be challenging due to the use of non-explicit or varying terms. To address this issue, this research aims to conduct a literature review by collecting papers that discuss the application of CV for smart city needs. The method used is a mapping review, with the following stages: 1) Establishing research questions; 2) Selecting relevant reference sources based on relevant databases; 3) Identifying appropriate keywords; 4) Conducting screening based on criteria; and 5) Extracting and synthesizing relevant data. For this research, we selected a total of 35 papers as the primary review. Our findings show that research trends and interests vary widely, with the most prevalent being in smart mobility components, which on average come from the IEEE Xplore Digital Library database. YOLO and CNN algorithms are also widely used to solve problems. Furthermore, we conclude that there are many benefits to be gained from the application of this technology to support the sustainable development of smart cities, including ensuring the quality of life of their inhabitants.

Learning activities are an indicator of the learner's desire to learn during the learning process. The pattern of learner action is related to learning activities. In this case, in extracting the learning process, it is necessary to collect a lot of data through analysis of the learning process. The purpose of this study is to recommend and report the performance of an activity tracking system equipped with visual artifacts as an educational data mining approach to analyze action patterns when learners complete the arrangement of program code lines in each programming problem. In this study, data were taken from activity recordings when learners used interactive learning media for a basic programming subject called TOLSYASUPI-EduMed which had problem-solving learning models embedded in their interactions. Learning Analytics is used as a method of this research and data relationships from learner actions during the learning process using the “if-then” rule. Log data is used for recording and detecting activities carried out by learners. We confirm that the results of the study are based on the findings of the data relationship that if the lines of program code are too long (more than five lines) then almost all learners experience a bottleneck condition. The completion time of each question and the number of iterations in completing the program code lines for each question have also been recorded and have a pattern of connection between the data. The information that has been obtained is then forwarded to teachers or stakeholders as key information to make appropriate feedback to learners based on the results as a means of analyzing and evaluating the programming learning process.

Sasirangan cloth is one of the traditional cloths owned by Indonesia and is a typical cloth originating from the province of South Kalimantan. This Sasirangan cloth has many motifs and is unique. Sasirangan cloth is also one of the potentials that can attract local and foreign tourists to visit South Kalimantan. However, in recent years, tourist visits to South Kalimantan have decreased due to the impact of the COVID-19 pandemic. Then it also has an impact on the delay in the implementation of the Banjarmasin Sasirangan Festival which is usually held annually. The next impact is a decrease in turnover and interest in shopping for Sasirangan cloth, so that employees who work for Sasirangan cloth craftsmen are dismissed and reduce people's income. So the purpose of this study is to report the results of the development of a Virtual Reality Game application called VR-SasiranganKu by integrating the interaction of Non-Player Character (NPC) behavior with the type of narrative in the simulation genre game. VR-SasiranganKu is recommended to introduce and at the same time promote Sasirangan cloth to users, then justify the reaction to knowledge and shopping experience, and evaluate user experience using the UX Honeycomb method. Respondents involved as many as 100 people who are local and national tourists. The results show that the interaction of NPC behavior can provide good direction to users regarding the introduction of Sasirangan cloth by presenting an appropriate interaction design based on the narrative and the theme of the NPC that has been adopted, the results of justification using VR-SasiranganKu can provide knowledge reaction and very good shopping experience, and based on user experience evaluation that VR-SasiranganKu has adopted a very good UX with an average score of 4.91.

Language differences are one of the obstacles to communication. Especially if you use certain regional languages such as Banjar Language. Banjar Language is the mother tongue used by the Banjar tribe in South Kalimantan Province, Indonesia. South Kalimantan is known as an area that has promising tourism potential and is the main gateway of the new nation's capital city. This causes many tourists to visit (overtourism). Tourists will face obstacles when communicating with local residents of Banjar. The purpose of this research is to produce a prototype of a tool in the form of a wearable technology-based translator application, using speech recognition with Python programming, then investigate the usability and sustainability opportunities of the prototype that has been made. A total of 200 respondents have been involved consisting of domestic tourists and local residents of Banjar, these respondents were involved in exploring needs and when evaluating usability. The results show that the prototype that has been made provides usability and is feasible to proceed to the implementation stage, as a means to help tourists from the archipelago and local residents of Banjar to communicate and also transact.

In this paper, we introduce the use of interactive educational media technology called TOLSYASUPI-EduMed with desktop-based development. It is recommended to help Vocational High School students with ICT expertise to learn the topic of branching control structures in basic programming classes. The open-posing type of problem-posing learning model has been embedded in the flow of system interaction, which consists of three system frameworks, namely (1) students submit a problem and answer recommendations, (2) the teacher checks recommendations and places them in the question bank, and (3) students solve problems and answers (compile the correct program code in order). A total of 36 students in the real class were involved. The result of the usage evaluation is that they enjoy using it, find it useful, solve useful problems, and prefer desktop-based. Then the justification for the influence that has been felt with an average value of 4.98 is Strongly Agree. Future work will be to develop mobile-based applications, improve application interaction and capabilities, and utilize log data for further analysis.

The use of technology to improve the experience and teaching and learning process in the classroom has been promoted now. One of these technologies is Augmented Reality (AR). Users are in a virtual space while still having nuances in real life called AR. AR has been proven to offer several solutions in the context of education, namely increasing learning involvement and increasing understanding of some materials. This study proposes AR-assisted learning media with the method of 3D Based Tracking and audio Marker, which is used by preschool children to recognize animals and fruits in English alphabetically, then analyze, evaluate, and know the effects on their use. The Extreme Programming (XP) method is used as an application development method. Application testing is done by black box testing, testing variations between distance, angle, lighting, background, and font size of the marker, and AR-Child response time to the detection of markers by the camera for the appearance of virtual objects. Thirty preschool children aged 4-6 years were involved in using the AR-Child application and analyzing application testing on the attractiveness and fun elements of students with fun testing. The effect of using AR-Child is seen from the learning outcomes at the end of the second meeting.

Language is one of the fundamental factors that distinguish humans from animals. Language allows individuals to live together, help solve problems and position themselves as cultured beings. Language is a communication medium that aims to understand each particular ethnicity and nation. Language comprehension allows increased awareness and value of closeness between individuals in an area. However, a large number of languages seem to be the cause of difficulties and misunderstandings about the meaning of certain words. This research provides alternative solutions for solving these problems. This solution can provide convenience in the process of understanding the meaning of language words, especially Banjar Language, by recommending an application called “BandoAR”. BandoAR is a translator application from Banjar Language to Indonesian. This application can work as a real-time application without requiring input media such as text that must be typed using a good camera quality and has autofocus characteristics on the camera. This study emphasizes the process of detecting and tracer texts that exist in the Banjar community. This research is intended to see how Augmented Reality technology can be applied in the text without markers and has different font sizes, backgrounds, and distances. The results show that software for Android smartphones, as a media translator in real time, can be used in almost every type of smartphone. Based on internal trials and the results of 160 respondents, this application can attract users’ interest, can be applied in real life, and as an effort to preserve Banjar Language culture.
