Abstract

This study discusses the development of a web-based sales information system to support the operations of Micro, Small, and Medium Enterprises (MSMEs) by applying the Waterfall methodology. The developed system includes main features such as product management, transaction processing, sales reporting, and user authentication. Manual testing using 10 test scenarios showed a functional success rate of 80%. The system implementation was able to speed up transaction time from five minutes to approximately forty-five seconds and reduce manual input errors by up to 75%. Usability evaluation using the System Usability Scale (SUS) resulted in a score of 84, indicating a very high level of user acceptance. The results of this study show that a web-based sales information system developed using the Waterfall approach can improve efficiency, accuracy, and effectiveness in managing sales for MSMEs.

Abstract

The development of information technology has encouraged the digitalization of literacy through the use of web-based digital books. However, most existing digital book platforms are still one-way systems and do not actively encourage user participation. This study aims to design and implement a web-based digital book sharing platform called OpenBook, which allows users to act as both consumers and contributors. The platform is developed using the Laravel framework and applies a credit system as an incentive mechanism for uploading and downloading digital books. The research method used is the System Development Life Cycle (SDLC) with the Waterfall model. Black-box testing results show that all main system features function properly and meet the specified requirements.

Abstract

The business process of selling and procuring products at PT. XYZ still relies on manual coordination and systems that have not yet been integrated, so workflows and process traceability are not yet optimal. This research aims to analyze and model these business processes using Business Process Model and Notation (BPMN). The research method used is descriptive research through observation and document study. The research data is in the form of activity flows, the role of actors, operational documents, and information on the use of the system in the sales and product procurement process. The results show that as-is business process modeling identifies flow inefficiencies, while to-be modeling results in more structured processes, integrated with information systems, and clarifies the roles and responsibilities of actors.

Abstract

Adequate sleep is a vital necessity for physical and mental health. This study aims to test the hypothesis of whether the average sleep duration in a mixed group (students and workers) is less than the recommended limit of 7 hours. Using a quantitative method with the One-Sample T-Test statistical test, this study analyzed data from 21 respondents collected through online questionnaires. Descriptive analysis results showed the average sleep duration of respondents was 6.64 hours with a standard deviation of 1.18. However, the t-test result showed a t_{count} value of -1.40, which was not significant at the 0.05 level. Therefore, statistically, there is not enough evidence to state that the population average is less than 7 hours. Additionally, a pattern of relationship was found between high gadget usage and anxiety with short sleep duration.

Abstract

Boutique Boutique digital agencies frequently encounter operational bottlenecks caused by disjointed workflows and reliance on manual data handling. Using Agency XYZ as a case study, this research identifies critical issues such as asset-caption mismatches and data security vulnerabilities arising from unmanaged 'Bring Your Own Device' (BYOD) practices. To address these challenges, this study applies the TOGAF Architecture Development Method (ADM) to design a comprehensive Enterprise Architecture tailored for small organizations. The resulting solution presents a blueprint for a centralized, web-based information system that seamlessly integrates with existing Google Workspace infrastructure and WhatsApp notifications. Key contributions of this design include an automated 'auto-switch' task delegation mechanism to prevent bottlenecks and a unified data model that establishes a Single Source of Truth (SSOT). The proposed architecture is projected to significantly reduce coordination latency, mitigate human error, and establish a secure, scalable operational framework for small creative teams.

Abstract

In the classroom, rules regarding writing authenticity often sound simple—do not copy, cite sources—yet in practice, they are rarely straightforward. This case study captures how assignment originality screening was conducted in a single class at UIN Sumatera Utara ($n=33$) over a three-week period, during which the lecturer combined detection tools (similarity matching/AI) with manual verification and structured feedback. We collected policy documents, examination results from two manuscript versions (pre- and post-revision), responses to an 11-item Likert questionnaire, open-ended comments, and conducted brief interviews with the lecturer and several students. Quantitative analysis presents per-item summaries, 95% confidence intervals, thematic subscales, and composite score distributions; qualitative analysis synthesizes recurring themes from comments and interviews, specifically focusing on rule clarity, perceived fairness, and identifying what genuinely assists students when revising their writing. The results indicate a neutral-to-positive attitude toward the process (composite mean $\approx 3.47$), peaking at the item regarding "increased intention to write authentically" after receiving feedback, and scoring lowest on "trust in the lecturer’s final decision." Based on these findings, we propose more transparent methods for explaining the basis of the lecturer's decisions (e.g., displaying text snippets and their original sources), feedback formats that directly address "what went wrong and how to correct it," and simple guidelines for interpreting similarity reports/AI indicators. While we acknowledge the study's limitations—a single class and a three-week duration—the findings are sufficiently rich to suggest practical measures that can be immediately adopted in similar classroom settings.

Abstract

The development of information technology plays an important role in supporting marketing strategies and improving services in the printing service industry. CV. Percetakan Sapitri still relies on conventional marketing and ordering methods, which limits market reach and service efficiency. This study aims to develop a company profile and printing service website using the prototyping model as a digital solution to enhance marketing effectiveness. The prototyping model was chosen because it allows direct user involvement throughout the system development process through iterative evaluation and refinement. The developed website provides features such as company profile, list of services and prices, printing gallery, and an online ordering form. System testing was conducted using the Black Box Testing method to ensure that all functions operate as expected. The results indicate that the website facilitates easier access to service information, accelerates the ordering process, and supports the expansion of marketing reach. Therefore, the prototyping-based website development contributes positively to digital transformation and competitiveness improvement at CV. Percetakan Sapitri.

Abstract

Employee attendance plays an important role in maintaining discipline and supporting work effectiveness. However, manual and fingerprint-based attendance systems still face several challenges, such as the possibility of proxy attendance, long queues during check-in hours, and difficulties in data recap. To address these issues, this study designs a web-based attendance information system equipped with GPS location validation and photo capture as proof of attendance. The research was conducted at PT XYZ using the Waterfall development method. Data were collected through observation, interviews, and documentation studies to formulate system requirements. The system design was modeled using Unified Modeling Language (UML), including use case diagrams and activity diagrams, which illustrate the interaction flows between employees and administrators. The implementation results show that the system successfully validates attendance location, stores photos as visual evidence, and facilitates administrators in managing employee and location data. Testing using the Black Box method confirmed that all functions operated as expected. Thus, the system improves the validity of attendance data, reduces fraud, and supports administrative efficiency within the company.
