Abstract

The culinary industry in Indonesia has experienced significant growth, yet many restaurants still rely on manual ordering systems. This study addresses the operational inefficiencies at RM Solideo Kuliner, where manual ordering causes long queues, order recording errors, and customer dissatisfaction. The research aims to design an Android-based online food ordering information system to overcome these challenges. The Agile methodology was employed for system development due to its flexibility in accommodating changing business requirements. Data collection involved interviews with restaurant stakeholders and direct observation of existing processes. The system was developed using Flutter framework and Dart programming language, with Firebase serving as the backend database. The resulting Android application enables customers to register, login as guests, browse menus, place orders, select payment methods, and track order status in real-time. Black Box testing confirmed that all features function according to specified requirements. Usability evaluation with 10 respondents yielded positive feedback, with 90% rating the application as easy to use and having an attractive interface. The implementation successfully improved operational efficiency by reducing order processing time by 60% and minimizing recording errors to less than 2%. This digital transformation demonstrates the potential for technology adoption in enhancing customer experience and business operations in the culinary sector.

Abstract

The management of waste banks often encounters issues such as manual transaction processing, limited transparency, and low public participation in waste sorting and recycling. This study presents the development of a web-based application for the Tonsea Recycle Center (TRC) aimed at improving operational efficiency, data transparency, and user engagement through a point-based reward mechanism. The development process adopted the Personal Extreme Programming (PXP) methodology, encompassing stages of requirement analysis, system design, implementation, testing, deployment, and maintenance. The application was developed using HTML, CSS, Python, Django, and SQLite, and includes features such as user authentication, transaction management, a reward point system, and an administrative dashboard[1]. Functional testing, user acceptance testing (UAT), and security testing were conducted to evaluate the system. The results demonstrate that the application effectively overcomes the limitations of the manual system by automating transaction records, enabling real-time data access, and enhancing transparency. Positive user feedback from UAT confirmed the system’s usability and functionality. This research concludes that the TRC web application significantly contributes to improving waste bank operations and community involvement. Future enhancements are suggested, including integration with digital payment systems, AI-based waste classification, and mobile application development to increase system accessibility and utility.

Abstract

This research aims to design and develop a healthcare service website for Puskesmas Modoinding to improve efficiency and accessibility of public health services. Previously, information delivery including doctor schedules, service types, operating hours, and patient registration was conducted manually, often causing delays and limited information distribution. The system was developed using the Rapid Application Development (RAD) method, comprising four phases: requirements planning, system design, development, and implementation. Data collection employed interviews, observation, and literature study with 12 stakeholders (10 patients, 2 administrators). The website was built using HTML, CSS, JavaScript, PHP, and MySQL database. Black Box Testing demonstrated 100% success rate across 28 test scenarios covering admin and patient interfaces. System Usability Scale (SUS) evaluation yielded average scores of 85.5 for patients and 87.5 for administrators, both exceeding the 'Very Good' threshold of 80. Ten core features were successfully implemented including online registration, queue status checking, and administrative data management. The developed website enables community members to access healthcare information remotely without physical visits, reducing average registration time by approximately 40%. This research concludes that web-based healthcare systems using RAD methodology can significantly improve service efficiency at community health centers while meeting user requirements and usability standards.

Abstract

Guest lecture management at FMIPA UNSRAT currently suffers from significant fragmentation across WhatsApp, Google Forms, and paper attendance, leading to data duplication, information inconsistencies, and administrative inefficiency. This condition hinders effective decision-making and stakeholder engagement. This study aims to design and develop a centralized Web-Based Guest Lecture Information System to integrate the entire event lifecycle, including publication, registration, digital attendance, and reporting. The system was developed using the Waterfall model with Laravel framework and MySQL database. Comprehensive evaluation involved Black Box Testing, User Acceptance Testing (UAT) with committee members, and User Perception Testing with students. Results indicate a 100% success rate in Black Box Testing across 42 functional scenarios. UAT yielded a 90.4% acceptance rate among committee members, validating operational feasibility and workflow alignment. Furthermore, User Perception Testing achieved a 91.04% satisfaction score among students, with Behavioral Intention reaching 93.6%. These findings demonstrate that the system significantly reduces data fragmentation and improves administrative efficiency compared to manual processes. The system is deemed feasible for immediate deployment, offering a robust solution for centralized academic event management. However, limitations exist regarding financial module integration. Future work should focus on API integration with the central university portal and automated honorarium processing to further enhance scalability and institutional adoption.

Abstract

This study evaluates the IT governance capability of the SIT GMIM integrated information system using the COBIT 2019 framework. SIT GMIM supports church data management and administration at synod, regional, and congregation levels but has never undergone a formal IT governance evaluation. Using a mixed-method descriptive case study design, data were collected through questionnaires, semi-structured interviews, direct observation, and document review from SIT GMIM managers at the central synod level. Capability levels were assessed for six DSS processes (DSS01–DSS06) and four MEA processes (MEA01–MEA04) using COBIT 2019 performance management guidelines, with gap analysis comparing current and target capability levels. The DSS domain achieved an average capability level of 1.17 (Level 1 – Performed Process), while the MEA domain achieved 0.75 (Level 1 – Performed Process). DSS02 reached Level 2 (Managed Process), while MEA04 remained at Level 0 (Incomplete Process). Gap analysis revealed DSS05 (Security Services) has the largest gap of 2 levels, while DSS03, DSS04, MEA02, MEA03, and MEA04 have gaps of 1 level. DSS01, DSS02, DSS06, and MEA01 achieved their targets. This study provides the first formal COBIT 2019 assessment of a church information system in Indonesia, establishing a baseline for IT governance improvement in religious organizations. Recommendations focus on documentation, incident logging, backup management, endpoint security, internal control evaluation, compliance monitoring, and assurance mechanisms
