Abstract

Cash payments are starting to shift towards an electronic or cashless payment system. While the process of transferring balances between ewallet at this time is considered less effective because it requires withdrawal from ewallet and replenishment using banks. This paper presents how to develop a Backend Server based on REST API Architecture using the NestJS framework on a ewallet transfer system. The development uses NestJS framework tools, MySQL database, API testing with Postman, Extreme Programming (XP) development method, and BlackBox Testing method. The result of this research is a server side system for transferring funds between ewallet in the form of a REST API that can be used by frontend and mobile developers.

Abstract

Budi Jaya Banjarindo operates in the machining and manufacturing sector and has a production system (make to order), which means the product is made according to consumer requests or design. This company uses machine equipment such as lathes, CNC machines, CNC Plasma Cutting, milling machines, hobbing and so on. Evaluation and redesign of the user interface system using Figma tools which will later be used by the workshop to optimize online product marketing. The system was designed using the UCD method. The final design result is a prototype which will then be assessed or tested using the SUS method to obtain an assessment from users. The SUS Score obtained was 65, based on these results it is included in the C range (range 60-70). These results indicate that the UI evaluation results are of good quality. The conclusion of redesigning the interface by adding several additional features, successfully meets user needs and the quality of test results is good.

Abstract

The digital transformation of population administration services has become a strategic effort to enhance the efficiency of public services, especially in regions undergoing administrative expansion. This study aims to examine the influence of digital literacy, trustworthiness, and system quality on user behavior in utilizing the SIPENDUDUK online service in Pekanbaru, Indonesia. A quantitative approach was applied using a survey method involving 400 respondents, determined through Slovin’s formula with a 5% margin of error. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to assess both measurement and structural models. The results reveal that digital literacy and trustworthiness significantly affect users perceived usefulness and ease of use, which in turn influence their intention to use and actual usage behavior. Among these, trustworthiness was found to be the most dominant factor directly affecting the intention to use, while digital literacy enhances user perceptions of system benefits and usability. Although system quality contributes to perceived ease of use and usefulness, it does not directly influence the intention to use. These findings highlight the importance of strengthening public trust and improving digital competence to support the successful adoption of digital government services, particularly in the context of dynamic population data management in newly expanded areas.

Abstract

The shrimp farming industry is crucial to Indonesia’s economy but faces challenges such as declining exports, low productivity, and limited technology adoption. Digital tools have been developed to support pond management through real-time water quality monitoring and data-based decision-making; however, user engagement remains low, indicating a gap between technology provision and adoption. This study aims to analyze factors influencing farmers’ acceptance of such digital technologies using the Unified Theory of Acceptance and Use of Technology 2 (UTAUT2) model. A quantitative survey involving 140 shrimp farmers in Central Java was analyzed using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The results show that performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation, price value, and habit significantly affect behavioral intention, while behavioral intention weakly influences actual use behavior, revealing an intention behavior gap. In contrast, use behavior is strongly driven by habit and facilitating conditions, and price value negatively affects intention. The study concludes that habitual use and technical support are more decisive than intention in promoting technology adoption, providing theoretical insights and practical implications for developers to focus on habit-forming design and continuous support for digital transformation in aquaculture.

Abstract

Low‑code application platforms have emerged as an innovative solution for developing information systems that are fast, flexible, and easily adaptable to meet the demands of the Fourth Industrial Revolution (Industry 4.0). In Indonesia, this technology has attracted particular attention as it helps organizations address challenges such as limited skilled human resources and the need for substantial investment. With low‑code, applications can be developed with minimal coding—even by non‑technical users—through intuitive visual interfaces and drag‑and‑drop components. This accelerates development, reduces costs, and enhances efficiency, enabling organizations to adapt more quickly to changing business needs and remain competitive in the industry 4.0 era. This study analyzes the implementation of low‑code through a descriptive qualitative approach, using a case study at PT Partner Niaga Indonesia, Tangerang, and involving ten informants from diverse roles (CTO, application manager, QA engineer, and others). Thematic and SWOT analyses reveal that low‑code offers major strengths such as rapid development, cost efficiency, and productivity gains, while also presenting opportunities to support digital transformation in Indonesia. However, limitations in customization, security concerns, and integration with legacy systems remain significant challenges. The findings suggest that low‑code is an effective and efficient solution for organizations seeking to accelerate digitalization, with practical implications including the need for workforce training, strategies to mitigate technical debt, and careful vendor selection. The study is limited by the number of informants and its focus on a single company; future research should include quantitative assessments of cost–benefit impacts and comparative studies across different industrial sectors.

Abstract

New student admission is a strategic process in higher education management because its success is determined not only by the number of students accepted, but also by the institution's ability to convert prospective students into re-registered students. This study aims to evaluate the effectiveness of the student admission selection pattern at the Islamic University of Indonesia for the 2023/2024–2025/2026 academic year based on the ability of each pattern to produce registered students. The study uses a quantitative approach with a descriptive evaluative method based on institutional data from the UII Monitor PMB system. The evaluation was conducted using conversion rate, enrollment yield, and withdrawal rate indicators. Data analysis includes descriptive statistics to describe admission performance, trend analysis to observe changes between periods, and Chi-Square and standardized residual tests to identify differences in the contribution of selection patterns to re-registration. The results show that the Cyber ​​pattern has the highest conversion rate of 27.79%, followed by CBT at 16.66%, PSB at 4.20%, and International at 3.38%. The chi-square test showed a significant difference between the selection patterns (χ² = 5029.271; p-value < 0.001). This finding suggests that data-based evaluation of selection patterns can inform decision-making in optimizing new student admission strategies.
