Abstract

The payment information system enables the entry of cash transaction data to SMA Teluk Panji through administrative staff (TU). The TU maintains the money payment reports that the students pay. This approach is useful and allows students to know more about the money they have to spend. This approach gives students complete knowledge in paper form. Useful reports to discover how much they charged and students who did not pay. Model UML is a visual language for modeling and designing information systems or applications. As support for the development of this information system, UML uses diagrams and text. Any significant modeling influences the design of useful applications. The system must meet its specifications and be capable of converting data into usable and efficient users. The black box evaluation method serves as a software assessment. The method operates from inside the unknown. When the system testers test this system as designed and focused on the school payment information system, the information system software is appropriately controlled by the external control mechanism. The prototyping method aims to summarise the application developed during these phases.

Abstract

One of the diseases distributed in the population is chikungunya fever transmitted by viruses from the genus Alphavirus, Togaviridae family, and transmitted by Aedes' bite aegypti and Ae mosquitoes. Virus albopictus involved. Chikungunya (CHIK) has three distinct symptoms: fever, joint pain (arthralgia), and skin infection (rash). Chikungunya (CHIK) is a self-limiting illness, and Chikungunya fever (CHIK) is not treated individually. Treatment efforts are symptomatic. Controlling and considering this disease is the right initiative. One consideration that can be achieved using expert system analysis is to use the form of certainty factor to derive the certainty value.

Abstract

The application of the ahp method to the information system in cooperatives managed by the Village-Owned Enterprises (Bumdes) of Silumajang Village, has the goal of making it easier for cooperative members to apply for loans, especially during the corona virus (Covid-19) period. In the application of the Analytical Hierarchy Process (AHP) method as a weighting method for this information system, the weighting used is divided into criteria and sub-criteria, given a value for each criterion and sub-criteria and providing recommendations for feasibility to Bumdes management in determining whether or not members are eligible. customers in getting assistance or loans from village-owned cooperatives (bumdes) with the assessment of each criterion and sub-criteria based on the calculation of the Analytical Hierarchy Process (AHP). With the application of this method, it is hoped that it can provide a solution for management in the midst of limited social interaction in making decisions for members or prospective customers of Cooperatives in borrowing business capital

Abstract

The increasing growth of technology necessitates that business professionals have particular, realistic, and actual data processing information systems as well as the confidence to operate within their human limitations. A strong data processing system has a significant impact on the formal and informal success of an organization. Therefore, the researcher aims to design and develop a web-based stock application utilizing the UCD (User-Centered Design) methodology and design modeling with UML (Unified Modeling Language), the most effective tool for object-oriented system development. The researcher employs the UCD approach because it is a method for designing and creating systems that place the users at the centre of the application creation and design process. In this study, the researcher collects data by identifying problems, conducting a literature review, and distributing questionnaires to assess user requirements. With a weighted score of 5 for respondents who strongly agree, 4 for respondents who agree, 3 for respondents who are neutral, 2 for respondents who do not agree, and 1 for respondents who strongly disagree, the results of the questionnaire are presented utilizing a Likert scale to measure a person's perspective, attitudes, and perceptions of an event. Thus, the program was developed in accordance with user requirements and is usable.
