Abstract

The DLU Ferry application has not fully met user expectations in terms of ease of understanding information on schedules, fares, and supporting features, and often experiences data synchronization issues that can undermine user confidence. This study aims to optimize the user interface of the DLU Ferry application to meet user needs for clear, accessible, and real-time information. The Design Thinking approach (Empathize, Define, Ideate, Prototyping, Testing) was chosen because it prioritizes user-centricity, facilitates a deep understanding of user needs and challenges, and enables the creation of sustainable and iterative solutions. Quantitative testing was conducted using the System Usability Scale (SUS) and A/B Testing. The final iteration of the SUS testing yielded an average score of 86, indicating the “Excellent” or “Best Imaginable” category in terms of usability, proving the success of the optimization efforts. However, there are areas for continuous improvement based on respondent feedback, including enhancing application performance and stability, refining the user interface, adding features, improving information quality and accessibility, and strengthening customer service and integration.

Abstract

The mosque is the Muslim community's place of worship and education. Regular worship occurs according to a timetable. However, educational activities require quite a long time, so the mosque management schedules learning activities periodically. In addition, mosque congregations have a very high diversity and density of activities, especially mosque congregations in urban areas. The management of urban mosques has difficulty organizing learning consistently because the congregation has difficulty meeting at the same time periodically. This paper offers a solution by teaching with a hybrid learning method between project learning and peer teaching. Projects are created based on the needs of the environment and the congregation. The project development team is formed from worshipers who can work on projects. Other congregants receive knowledge through the project development team when the project is in the process of being created and run. This hybrid learning was experimented with by creating an aquaponics project. Aquaponics is operated with solar electricity. The project development team consists of a congregation of children to parents. The project has successfully transferred knowledge to the project development team members. The project operation attracts non-team worshippers to discuss independently with team members. Some non-team members have developed fish farming independently.

Abstract

The growing implementation of governance models in higher education institutions has raised new challenges in accountability and performance. Although risk management and analysis in governance has received some attention in the literature, there is a lack of studies focusing on the use data-driven clustering algorithms. The current research focuses on the development and assessment of a web-based risk management information system that incorporates clustering principles to identify and map non-academic governance risks. The study followed the CRISP-DM framework and analyzed 678 risks from the Internal Audit Unit (SPI) of Politeknik Negeri Malang. The system employs K-Means clustering analysis to classify the risks into tiers based on performance indicators, budget, and risk severity. The system is equipped with data upload, preprocessing, logging, and cluster visualization modules. A comparative analysis of K-Means, DBSCAN, and Hierarchical Clustering showed that K-Means yields the best cluster quality with a Silhouette Score of 0.48, in comparison to DBSCAN (-0.705) and Hierarchical clustering (-0.395) . The developed system generated five distinct clusters corresponding to risks of varying settlement priority viz. very high, high, medium, low, and very low. The functional and usability assessments of the system confirmed that it provides automated and actionable insights on risks in a user-centric manner. The study has demonstrated the clustering of governance risks in higher education using K-Means is feasible. The incorporation of predictive analytics and real-time data would best support the research in active risk avoidance.

Abstract

In the digital era, the transformation of information systems has become a crucial element in enhancing the competitiveness of micro, small, and medium enterprises (MSMEs). This community service initiative focuses on the digitalization of sales operations at Yogurt Bark Fruity, a student-run culinary business offering healthy yogurt-based products. Previously, sales activities were conducted manually via WhatsApp and Instagram, which posed risks of recording errors and limited market reach. The proposed solution involves the development and implementation of the yogurtSalesPro application, based on the PPEPP method. This system is designed to integrate the management of transactions, inventory, customer data, and sales reporting. Evaluation using the System Usability Scale (SUS) resulted in a score of 71.5, indicating a good level of usability. Additionally, assessment through the Technology Acceptance Model (TAM) revealed high scores across all indicators, with Perceived Usefulness and Perceived Ease of Use each achieving 100% positive responses. The application’s effectiveness is reflected in improved recording efficiency, a reduction in transaction errors from 15% to 2%, and an increase in both daily transactions and new customers. Beyond operational efficiency, the application also supports digital literacy and student entrepreneurship. Thus, yogurtSalesPro proves to be an effective solution in fostering innovation and sustainability for technology-based MSMEs.

Abstract

The School Literacy Movement (GLS) aims to foster youth character through a culture of literacy (reading and writing). However, in the presence of the Covid-19 outbreak, Indonesian education needs to use online media to keep learning going. Many types of platforms are used for online learning media, but all of these media do not support school literacy activities, so school literacy activities do not run as usual. Based on these problems, a solution was created, namely an application that makes it easy for literacy activities to take place online. Students can access this application to do online literacy via a laptop or smartphone. This application makes it easier for teachers to monitor the course of online literacy programs. The results of this study are indicated by functional testing on all features obtaining a 100% valid percentage. Tests on users get an average percentage of more than 80%. The test results prove that this application can be accepted by students, teachers and admins at State High School 1 Geger Madiun to make literacy activities more effective and efficient.
