Fraud is a phenomenon that continues to exist in society with a modus operandi that continues to evolve with the times. The mode of operation of fraud is continually evolving with technological advancements, globalization, and consumer behavior shifts. In today's digital age, social media is important in spreading information regarding fraud. Twitter is a social media platform that is widely used. Twitter provides easy and fast access to relevant information. As a result, to raise fraud awareness, it is critical to study the mode of operation of fraud spread on social media, particularly on Twitter. The Latent Dirichlet Allocation (LDA) approach is used in this work to classify and identify fraud issues often addressed by Indonesian Twitter users. By applying LDA modeling, this study aims to understand more comprehensively the fraudulent topics that often appear on Twitter. The research found that seven fraud topics are most commonly discussed by Twitter users in Indonesia, with the highest cohesion value of 0.491899.

Based on previous research conducted on elementary school students, it was found that there are still many errors in the use of EYD or KBBI rules, such as errors in the use of capital letters and the use of words. The lack of learning media outside of school triggers students' lack of understanding. Using technology-based learning media in games is exciting and can help improve students' understanding outside school. Using educational games as out-of-school learning media has several advantages, namely ease of access and higher student interest in playing. In developing games, an attractive appearance is needed and is the need of elementary school students. This is adequate and can increase students' interest in using the game as an out-of-school learning media. Therefore, an appropriate design method is needed to design the appearance to be attractive and by the needs of students, one of which is Human-Centered Design (HCD). This method involves users directly during the design process. By applying the HCD method, this research aims to design the interface of the "CerdasEYD" educational game that suits the needs and answers the problems that students have. Testing is carried out using the System Usability Scale to measure the success of the interface that has been designed. Through this test, the results obtained in the form of an average score of 95 indicate that the design has met the needs and answered the problems that students' problems.

The website is one of the media used by some educational institutions to convey information. One of them is the Department of Informatics at the Universitas Islam Indonesia (UII). One of the basic things that need to be considered when developing a academic website is the user experience (UX) a user has when engaging with a website. User experience measures the comfort level of a user when interacting with a product. User experience needs to be evaluated regularly so that the website can continue to meet the expectations of its users. However, there has been no research related to evaluating or testing user experience on the UII Informatics Department website. This study aims to assess the level of experience of UII Informatics Department website visitors. This study employed quantitative research methods, specifically the User Experience Questionnaire (UEQ) method. Using the mean calculation, the UII Informatics Department website received positive assessments on the dimensions of perspicuity, efficiency, attractiveness, dependability, and stimulation, but received negative evaluations on the novelty dimension. According to the benchmark analysis, the aspects of perspicuity and efficiency are above-average. While the dimensions of novelty, stimulation, dependability, and attractiveness are below-average. The results of this study can be used as a reference for developing a website for the Department of Informatics with a version that is more in line with user needs.

E-commerce is an alternative for individuals to look for and purchase things. Unfortunately, despite its importance in digital market connectedness, e-commerce has not played a significant role in the continuity of the halal market. This study aims to look at the differences in halal product sales in Muslim majority and minority countries, which can stimulate the availability of halal products on e-commerce and increase halal product exports, as well as make it easier for Muslim communities to buy halal products. There was no previous research on a similar topic, notably one that specifically explored the sale of halal products through e-commerce. Halal-labeled product data was taken from Lazada e-commerce using web scraping (using the Selenium package in the Python programming language), which was then carried out by Kruskal-Wallis analysis. According to the findings, the average sales of halal products in Indonesia, Malaysia, Singapore, and Malaysia varies significantly. However, in the pairwise or combination test comparing groups of countries, it was discovered that the average sales of halal products in Indonesia and Singapore were identical.

Data is a new mind; data is gold; data is a new mine. This is a parable that was as familiar in the digital era as it is today. Data can be utilized, among other things, to improve operational efficiency, spur innovation in a business, understand user needs, and encourage decision-making. Data from e-commerce can be collected in a variety of ways, including web scraping techniques utilizing Python and libraries like Selenium, Beautifulsoup, and Time. The web scraping methods at Shopee and Tokopedia used in this study are HTML Parsing and CSS Selector. This study found that the HTML Parsing and CSS Selector methods cannot be used for web scraping on Shopee owing to bot and CAPTCHA detection mechanisms. However, this method was successfully used on Tokopedia. We conducted 10 web scraping attempts on two product pages, which resulted in around 160–166 data points each time, with 3–18 duplications of data. The average execution time of a program is 1 minute and 0.5 seconds.

AMGM mobile Lab application is a design application supporting documentation of water sample management data. There is a management support system in the form of an intranet. Nevertheless, access to the system is restricted to the office. Naturally, this is less effective since officers must first return to the office in order to enter sample data, and this cannot be done in real-time while they are out in the field. Thus, in order to facilitate these operations, mobile application development is required. User experience analysis is necessary to provide an inventive UX design, which is then required to satisfy laboratory requirements and the company's expectations for the application design. The objective of this study is to use user experience research as a foundation for future application development. In order to do user experience analysis, the User Experience Questionnaire (UEQ) approach is used. The test results reveal that the assessment falls into the excellent category for attractiveness (1.86) and dependability (1.82). The efficiency (1.85) and novelty (1.24) scales are categorized as good. The perspicuity (1.71) and stimulation (1.21) measures are categorized as above average. The mean of the entire scale exceeds 0.8, indicating that people assess all features positively.

Preserving the Javanese language is a collective responsibility to safeguard Indonesia's cultural heritage. This study aims to develop Sinau, a Javanese language learning game for early childhood (ages 4–8), focusing on vocabulary and unggah-ungguh (Kromo and Ngoko) with correct pronunciation. Utilizing the Game Development Life Cycle (GDLC) and Guided Discovery methods, the game was designed to facilitate active learning both at home and school. GDLC encompassed pre-production (concept, teaching methods, and prototype development), production (game creation with Unity, incorporating educational content, visuals, and sound), and post-production phases. Testing involved 10 second-grade students and 2 teachers, with observations despite the game's primary target being younger children. Participants evaluated the game by playing it and completing a 10-question Likert-scale questionnaire. Usability was measured using the System Usability Scale (SUS), resulting in a score of 74.17, indicating an acceptable level with a good adjective rating. These results demonstrate that Sinau is well-received and effective for Javanese language learning. While the study did not directly test early childhood learning outcomes, the findings suggest the game's potential for educational use, with recommendations for improving user experience and content to enhance its effectiveness further.
