PERANCANGAN SISTEM INFORMASI ANALIS BREAK EVEN POINT DAN STOK PADA BUDIDAYA AYAM POTONG BERBASIS WEB

Although broiler chicken farming offers many benefits, there are also risks of losses, especially when production costs are not accurately recorded, leading to inaccurate per-unit pricing that can harm farmers. To assist farmers in accurately determining the Break Even Point (BEP) price for each chicken, a web-based cost and stock management information system for broiler farming has been developed. To provide a clear and sequential software lifecycle approach, this system was built using the waterfall method, which includes the stages of requirements analysis, design specifications, coding, testing, and maintenance. Each stage produces measurable outcomes before proceeding to the next. The development results indicate that the system successfully records the total production costs, including detailed costs for feed, medicine, operational expenses, and chicken stock. By using the formula BEP = total production cost/number of live chickens, the system achieves accurate pricing for broiler chickens. Based on these findings, future research is suggested to improve the user interface for greater appeal, optimize system accessibility on mobile devices, and integrate this system with other systems.

PERANCANGAN SISTEM INFORMASI AKUNTANSI BERBASIS FRAMEWORK CODEIGNITER PADA MASJID AN NUR KABUPATEN SANGGAU

This research aims to develop an accounting information system that uses the codeigniter framework, with a focus on making it easier to prepare financial reports for the An Nur Mosque. The research method applied is descriptive qualitative with a waterfall method approach which includes various steps such as needs analysis, design, implementation and testing. The results of this research show that the design of an accounting information system can help non-profit organizations, especially the An Nur Mosque, in preparing more accurate and transparent financial reports.

Leveraging Gamification in Science Learning for Secondary Students

This project aims to study the usefulness of incorporating gamification for science learning, for secondary school students. Ever since, the Science subject has been a hassle to the students, as well as the teachers. Therefore, a web-based system with gamification has been proposed. The waterfall model was chosen as the project's methodology, which consists of planning, analysis, design, implementation, testing, and documentation phases. Firebase was used as the cloud database to ease data storage and analysis. The selection was made to ensure the data from interactive activities such as watching films and doing exercises was securely gathered and used. Students earned points, badges, and were ranked as they performed assignments, adding a competitive element to the learning experience. A usability test was carried out to assess the success of the gamified learning platform using PSSUQ (Post-Study System Usability Questionnaire). The survey participants were chosen randomly from a group of high school students and teachers. After using the gamified website, they were asked to submit feedback by answering 16 constructed questions. Positive feedback was gathered from the survey, as most of the questions recorded mean values between 4.0 and 4.5. Hopefully, this study will provide further information regarding the effectiveness of gamification in learning, particularly in science learning for secondary students.

WATERFALL MODEL OVER PCD.UCT MODEL REVIEW

Abstract. The software development life cycle (SDLC) has seen the evolution of numerous models, each tailored to meet specific project needs. Among these, the Waterfall Model has been a longstanding, traditional approach, characterized by its linear and sequential phases. In contrast, the PcD.UcT Model, a relatively newer framework, advocates for a more iterative and user-centered approach. This paper presents a comprehensive review of the Waterfall Model, evaluating its strengths and limitations in modern software development. It contrasts these findings with the PcD.UcT Model, analyzing how its principles better align with contemporary project demands, particularly in terms of flexibility, user engagement, and iterative refinement. Through this comparative analysis, the paper aims to provide insights into the applicability and effectiveness of each model, offering guidance for software development teams in choosing the appropriate methodology for their projects. Since the waterfall development methodology, the key requirements in system development strategies have shifted from processes to users. Because the process as well as the customers are both equally important, employing either a predictive or an adaptive methodology is extremely difficult. The primary goal of this work is mainly combining and then evaluating all the relevant methodologies in order to create a HydroGIS that accurately automates the complexities of the hydrology process in a HydroGIS environment while meeting all user requirements.

Android Based Sports Infrastructure E-Booking Application at Provincial Youth and Sports Office Using Waterfall Method

Booking is an agreement process in the form of ordering goods or services. The Youth and Sports Service (DISPORASU) is a government agency under the auspices of the Governor of North Sumatra. DISPORASU provides sports infrastructure that can be used by the general public by rental method. In the rental process, DISPORASU still applies the direct rental method, by coming to the DISPORASU office in Medan City, so this results in a large number of tenants piling up at the same time. Therefore, a system is needed that helps tenants in carrying out the infrastructure rental process. The concept is an Android-based Sports Infrastructure E-Booking application. This application was built and designed using the waterfall model and UML (Unified Modeling Language) with several diagrams, namely Use Case Diagrams, Activity Diagrams and Class Diagrams. The programming language used is Dart, Flutter Framework and Firebase as the database. By building this sports infrastructure E-Booking application, it is hoped that it can help improve performance in future business processes and become a reference for employees/staff in this agency itself.
