Abstract

This research investigates the effectiveness of the E-Catalog system in supporting goods and services procurement at Sesko TNI Bandung. As a digital procurement platform introduced by the government, the E-Catalog aims to increase transparency, accuracy, and process efficiency. Despite these intended advantages, its adoption remains constrained by users’ limited familiarity with digital procurement practices and their long-standing reliance on manual procedures. To address this issue, the study applies the Technology Acceptance Model (TAM) as the analytical framework, focusing on perceived usefulness, perceived ease of use, user attitudes, and behavioral intentions toward system utilization. A mixed-methods approach with a sequential explanatory design was employed. The quantitative phase involved distributing structured questionnaires to procurement personnel to measure key variables related to system acceptance. Subsequently, qualitative data were obtained through in-depth interviews with procurement operators to clarify and deepen the interpretation of statistical results. The study finds that perceived usefulness and perceived ease of use significantly shape user attitudes and intention to utilize the E-Catalog. These variables collectively contribute to improving the overall effectiveness of the procurement process. The results highlight that the more users perceive the system as beneficial and easy to operate, the more likely they are to adopt it consistently, thereby enhancing operational efficiency at Sesko TNI Bandung. This research underscores the importance of increasing digital literacy, strengthening system socialization, and providing continuous training to optimize the performance of the E-Catalog platform.

Abstract

The rapid development of information technology has encouraged governments to adopt digital systems to improve the quality of public services, particularly through the implementation of e-Government at the Department of Population and Civil Registration (Disdukcapil) of West Java Province. However, the effectiveness of digital services is not only determined by the availability of information but also by the level of accessibility that ensures equality for all users, including persons with disabilities. This study aims to evaluate the accessibility of Disdukcapil websites across 18 regencies and cities in West Java using Site Analyzer and AudioEye tools, based on the Web Content Accessibility Guidelines (WCAG) 2.2 standards. The findings reveal that most websites fall into the moderate category in terms of design and accessibility, but remain weak in search engine optimization and content quality. The AudioEye audit identified recurring accessibility issues, including unlabeled links and buttons, missing skip links, unlabeled form fields, disordered headings, and interactive elements without proper identification. These violations not only create technical barriers but also have psychological impacts on users with disabilities, such as frustration, mental fatigue, anxiety, and feelings of exclusion in digital interactions. The study underscores that failure to meet accessibility standards is not merely a technical issue but also reflects a form of social exclusion that re-duces the quality of life for vulnerable groups. Therefore, the development of Disdukcapil websites must prioritize the gradual implementation of WCAG 2.2, improve navigation struc-tures, and provide consistent labeling to realize inclusive, effective, and sustainable digital public services.

Abstract

Despite rising NBA Achilles injuries linked to low-top shoes, models like the Nike KD series continue to enjoy massive commercial success. This study investigates this paradox by examining whether athlete identification and aesthetic shoe design override perceived injury risk in shaping purchase intention. Using a quantitative correlational design, data were collected from 300 basketball enthusiasts in Indonesia, purposively selected for their interest in the NBA and awareness of Kevin Durant. Results confirm that athlete identification and aesthetic design directly drive purchase intention, whereas perceived injury risk acts as a significant deterrent. Notably, moderation analysis reveals that safety concerns attenuate the emotional drive of athlete identification but unexpectedly amplify the influence of aesthetic design. Consequently, while athlete identification is the primary driver, aesthetic design becomes paramount when injury risk is taken into account. This indicates that consumers actively repurpose risky low-tops into casual streetwear, prioritizing visual appeal over performance. Therefore, sportswear manufacturers should market low-top models as lifestyle apparel while improving their structural integrity.

Abstract

This study discusses the design of an Internet of Things (IoT)-based attendance system using RFID and NodeMCU ESP8266 to support and improve the efficiency of teacher attendance management at MTs Al-Ikhlas Cicalengka. The primary problem motivating this study is the reliance on a conventional manual attendance system, which is highly vulnerable to recording errors (human error), time inefficiencies during daily data recapitulation, and the risk of physical document loss or damage. Therefore, digital transformation is urgently needed. The proposed system integrates several hardware components: RFID RC522 as the identity card reader, NodeMCU ESP8266 as the main controller and internet (Wi-Fi) connector, and a 16x2 LCD as an interactive information display. The attendance data is directly transmitted and stored in a cloud-based Google Spreadsheet. The system was programmed using Arduino IDE to operate automatically. This study utilized a design and prototyping method by testing 10 registered RFID cards belonging to the teachers. The test results demonstrated that all cards were successfully read, and attendance data were accurately stored in Google Spreadsheet with a 100% success rate. The average system response time was recorded at a very fast 2.2 seconds. In conclusion, the implementation of this IoT-based attendance system is proven to be effective in minimizing data manipulation, accelerating the recording process, and generating attendance recapitulations that are more transparent and easily accessible. The contribution of this research is providing a practical, affordable automation system that can serve as a reference model for other secondary educational institutions in digitally transforming their administrative management.

Abstract

This research is motivated by the increasing use of e-learning systems in Indonesian universities post-COVID-19 pandemic, which has accelerated digital transformation in the learning process. Although the implementation of e-learning is becoming increasingly widespread, students' acceptance levels of the system still vary and are influenced by their perceptions of ease of use and perceived benefits. Therefore, this study aims to analyze student acceptance of the e-learning system using the Technology Acceptance Model (TAM) approach, focusing on the influence of Perceived Ease of Use (PEOU) on Perceived Usefulness (PU), as well as the influence of PEOU and PU on Behavioral Intention to Use (BIU). This research uses a quantitative approach with an associative-causal design. The research respondents were 100 active students who had used the e-learning system for at least one semester, selected thru purposive sampling. Data was collected online using a closed questionnaire and analyzed using simple linear regression and multiple linear regression techniques. The research findings indicate that PEOU has a positive and significant effect on PU. Furthermore, PEOU is also proven to have a positive and significant effect on BIU, while PU does not show a significant effect on BIU. These findings suggest that the ease of use of the e-learning system is the dominant factor in shaping students' interest in using e-learning continuously. The results of this research are expected to contribute theoretically to the development of technology acceptance studies in higher education and serve as a basis for practical recommendations for universities in designing and managing more effective, adaptive, and user-needs-oriented e-learning systems.
