Abstract

In a company, there are several areas it manages, such as sales, purchases, inventory, marketing, production, and many other fields. Inventory, which is one of those areas, becomes a crucial center in the sustainability of the company's operations. This is because inventory has a relationship with sales and purchases, or is related to incoming and outgoing goods. Therefore, special attention is needed in this area of inventory. Inventory is not only related to goods but also to raw materials, depending on the type of company being run. In the inventory of raw materials specifically, it is essential to clearly understand the raw materials available in the company so that it can meet the company's needs in producing goods. To obtain this clear information, good information systems are certainly required. However, in reality, there are still many companies that use a manual system in managing their inventory data. This can obviously lead to several problems such as the information obtained regarding the final condition of the raw materials not being updated properly due to recording errors made on the incoming and outgoing raw materials. This condition results in the preparation of inventory reports being incorrect, thus making the information provided inaccurate. If this continues, it will negatively impact the company's survival. The company may incur significant losses and be unable to compete with other companies. Therefore, such companies need the development of a system that will transform from a manual system to a computerized system. With the hope of resolving the issues faced. In the process of developing the system, it is also necessary to choose the right model, such as the Rapid Application Development model. Because in this model, the existing stages can be carried out clearly and systematically and can have a short time estimate in the development of the system. The final result of this system development can be an inventory application that can be used to assist in managing its inventory data.

Abstract

This study aims to design an integrated, web-based Internship Management Information System specifically for the Department of Communication and Informatics of East Kalimantan Province. The background of this research lies in the existing manual internship administration process, including participant registration, document verification, daily attendance recording, performance evaluation, and certificate issuance, all of which are time-consuming and prone to errors. The research adopts the System Development Life Cycle (SDLC) with the Waterfall model, encompassing requirements analysis, system design, and the development of user interface mockups, without proceeding to actual system implementation. Requirements analysis was conducted through literature review, observation, and interviews with stakeholders to formulate the functional and non-functional needs of the system. The result is a comprehensive system blueprint, consisting of main process flowcharts, UML diagrams (use case, class, activity), and user interface designs for admins, participants, and supervisors. The system design enables online registration, digital data verification, daily reporting by participants, real-time monitoring by supervisors, automated evaluation based on specific criteria, as well as digital certificate generation and verification by the admin. This blueprint is expected not only to accelerate and simplify the internship process but also to enhance transparency, accountability, and efficiency in talent data management within the Department of Communication and Informatics of East Kalimantan Province. Furthermore, the system design can serve as a model for developing similar applications in other government agencies.

Abstract

Financial management in GKII Muara Asa Church has traditionally been conducted manually using physical books and spreadsheets, making it prone to recording errors, reporting delays, and lack of transparency for church members. To address these issues, a web-based Financial Information System (FIS) website was developed to facilitate transaction input, digital data storage, real-time financial reporting, and information access for members. The system was built using the Waterfall model of the System Development Life Cycle (SDLC), including planning, analysis, design, implementation, testing, and maintenance phases. Technologies used include Laravel as the backend, MySQL for database management, and Bootstrap for frontend development. Functional testing showed that all core features such as login, transaction input, data search, and backup operate as expected with an average response time under 2 seconds. The implementation proves that the system successfully improves efficiency, accuracy, and transparency in church financial management.

Abstract

Post-Traumatic Stress Disorder (PTSD) is a serious mental health condition that can develop after an individual experiences a traumatic event. Early diagnosis of PTSD symptoms is crucial to prevent more severe psychological and social impacts. This study aims to develop a mobile-based expert system application that implements the Dempster-Shafer method to independently diagnose the confidence level of PTSD symptoms. The system is designed with three main components: biodata input, a symptom selection interface based on 9 indicator questions, and an inference engine utilizing the Dempster-Shafer method with a Likert scale to assess the severity of trauma experienced by respondents. Testing was conducted on 47 respondents, and the analysis results showed that 19.1% were in the safe category, 4.3% in mild PTSD, 12.8% in moderate PTSD, and 63.8% in severe PTSD. Validity testing indicated that all symptom items had correlation values (r-calculated) greater than 0.2876, confirming their validity, and the instrument’s reliability was measured at α = 0.806. The application is capable of providing an initial diagnosis along with recommended actions based on the severity level of PTSD. This study demonstrates that applying the Dempster-Shafer method in a mobile application offers an effective, efficient, and accessible alternative solution for early PTSD diagnosis, especially for individuals with limited access to professional mental health services.
