Abstract

The increasing prevalence of lifestyle-related health issues highlights the necessity for innovative solutions to promote healthier habits. This study aims to design a better and more suitable user interface (UI) for the user experience (UX) of a mobile calorie deficit application using the Design Thinking method. The primary objective is to create a user-centric UI design that enhances user engagement and supports weight management goals. Through a comprehensive Design Thinking process, which includes empathizing with users, defining problems, ideating solutions, prototyping, and testing, we developed a UI design tailored to the needs of individuals seeking to manage their calorie intake effectively. The testing phase involved two scenarios. The first scenario achieved a miss click rate of 0-9% and a usability score ranging from 91 to 100. User feedback was continuously integrated to refine the design, ensuring usability and functionality. The results demonstrate that the well-structured UI design effectively improves user satisfaction and interaction. This research underscores the value of Design Thinking in developing user-centered interfaces for health management applications.

Abstract

Rapid technological developments have changed the process of searching for boarding houses, which has been done manually through brochures, pamphlets, or banners. These conventional methods are considered inefficient because of their limited reach and the time required, especially for prospective tenants from outside the area. This study designs and develops a mobile-based e-boarding house application with features such as searching, booking, and digital payments, using the Rapid Application Development (RAD) methodology. This application makes it easier for users to find boarding houses that suit their wishes while making it easier for boarding house owners to manage room availability, tenant data, and payment history in a structured manner. The test results show that the e-boarding house application runs optimally without technical constraints and is effective in meeting user needs. By providing digital solutions, this application can increase the efficiency of searching and managing boarding houses, so that the process becomes faster, more practical, and more modern. Implementing this system provides significant benefits for prospective tenants and boarding house owners, namely increasing accessibility and management in the boarding house industry

Abstract

The growing demand for footwear and accessory care reflects an increasing awareness of cleanliness and personal appearance. This study focuses on a cleaning service business specializing in shoes, bags, and strollers, with shoes as the primary focus. Operational challenges, including inefficient customer communication and delays due to high demand, impact customer satisfaction. Using the Design Thinking method, this research develops a user-centered User Interface (UI) and User Experience (UX) for the business's application. The Design Thinking process—empathize, define, ideate, prototype, and test—helped identify pain points and generate tailored solutions, such as improved navigation and task flow. Usability testing involved 18 participants performing key tasks, including booking services and tracking orders, with success rates and error metrics as evaluation criteria. The testing yielded a 70.6% task completion success rate, indicating improved service efficiency. However, the 54.4% misclick rate, higher than typical benchmarks for similar applications (30–40%), highlights significant navigation challenges. Future iterations will focus on refining the interface layout and enhancing task clarity to reduce errors and improve usability. These findings emphasize the value of iterative, user-centered design in addressing operational inefficiencies and enhancing the customer experience.

Abstract

The advancement of information technology (IT) has become essential for organizations, including Bank Mandiri, where it underpins critical business functions. This study examines the implementation of IT governance at Bank Mandiri’s Girian branch using the COBIT 2019 framework, a comprehensive tool for managing IT processes effectively. Through a qualitative case study approach and interviews with key stakeholders, the study analyzes 40 IT processes across 11 design factors, with each factor scored between 75 and 100 to prioritize their importance. High-priority processes, such as Managed Solutions Identification and Build (BAI03), Managed Requirements Definition (BAI02), Managed IT Changes (BAI06), and Managed Projects (BAI11), are identified as critical to operational stability, customer satisfaction, and strategic alignment. These objectives play a fundamental role in resource allocation, supporting seamless IT operations and enhancing customer service. Processes with lower scores are deprioritized, allowing strategic focus on high-impact areas. This prioritization framework helps ensure efficient resource use, aligns IT governance with organizational goals, and reinforces the branch’s commitment to achieving reliable, customer-focused IT management. The study underscores the indispensable role of IT in supporting Bank Mandiri’s operations, where any IT disruption could significantly impact business continuity and customer satisfaction.

Abstract

The process of designing a mobile application requires a user-centered approach that addresses real-world problems through innovation and creativity. This study focuses on applying the Design Thinking method to develop the UI/UX for a shoe repair service application, aimed at enhancing the user experience for both customers and service providers. The Design Thinking process consists of five stages: empathize, define, ideate, prototype, and test. Through these stages, the study identifies key pain points, such as customers’ difficulties in locating service providers and estimating repair times, and service providers’ challenges in managing customer flow and payment methods. Solutions generated include real-time updates on vendor locations, transparent wait times, and multiple payment options. Prototypes were developed and tested to assess usability, with the research highlighting the need for continuous iteration to improve user experience. The usability testing revealed mostly positive results, with an average usability score of 88.8 across scenarios. However, certain areas, particularly screens in scenario 5, showed higher error rates and required further refinement. This study demonstrates the effectiveness of the Design Thinking method in solving complex design challenges, offering innovative solutions tailored to user needs. The Shoe Repair application’s design not only enhances functionality but also addresses specific challenges faced by users, emphasizing the importance of an iterative, user-focused approach in UI/UX design

Abstract

IT is crucial for organizational performance and competitiveness, especially in healthcare, where service quality affects patient outcomes. Effective IT governance aligns investments with goals, delivers value, and reduces risks. This study assesses IT governance priorities at RSUD ODSK using the COBIT 2019 framework, identifying key governance and management objectives. The research employs a structured methodology, beginning with problem identification and then data collection through structured interviews using the COBIT 2019 Design Toolkit and the analysis of 10 Design Factors. These factors help determine the most critical governance objectives in RSUD ODSK's operational environment and strategic priorities. Findings indicate that Client Service/Stability is the hospital's top strategic priority, supported by key enterprise goals, including compliance with external regulations, business-service continuity, and internal process optimization. The prioritization process highlights Managed Assurance (MEA04) and Managed Security Services (DSS05) as the most critical governance objectives, both receiving importance scores of 100%, emphasizing the need for continuous IT performance monitoring and strong data security measures. Other highly prioritized objectives include Managed Security (APO13) at 85% and Managed Compliance with External Requirements (MEA03) at 70%, reflecting the hospital's focus on regulatory adherence and risk management. The results provide practical guidance for RSUD ODSK in improving IT governance, aligning IT with organizational goals, and ensuring reliable IT services to enhance patient care and operational efficiency. This study contributes valuable insights for hospitals seeking to strengthen IT governance using COBIT 2019.
