Abstract

With technological developments in various fields that influence human life, one of which is the culinary field. However, when showing the food and drink menu from a foodcourt, there aro no props available to display the menu. Currently, when showing food and drink menus to customers, only 2D images are used. By utilizing augmented reality technology, it is hoped that it can help foodcourt in presenting food and drink menus to make them more attractive because augmented reality can be a tool to display menus in 3D form. By using 3D visuals, it is also hoped that it can help customers to know more about the menus available at the foodcourt. With augmented reality supported by the markerless method, the foodcourt can display the available menus in 3D as well as details of each menu. In modelling 3D objects about the menus, software in the form of Blender will be used. For system development, the prototype method will be used so that the steps of development are known.

Abstract

The annual count of individuals afflicted with diabetes is rising. As to a survey carried out by the International Diabetes Federation (IDF), the global diabetes population is approximated to be 537 million by 2021, and this number is projected to increase further to exceed 780 million by 2045. The study's primary goal is to diagnose and forecast whether or not a patient has diabetes. The approach makes use of logistic regression, a statistical tool for modelling individual classifications of diabetes presence or absence. According to the diabetes risk prediction results, 43% of respondents gave consideration to the condition. Consequently, it has been demonstrated that normalisation enhances the accuracy of diabetes risk prediction using logistic regression methods. Based on the variables included, it is anticipated that the predictions made by this model will serve as a guide for the general public in understanding healthy living and diabetes prevention.

Abstract

In the digital era, information systems play an important role in improving operational efficiency, accelerating the decision-making process, and providing competitive advantages for organizations. PT. Rofenni Primajaya, which is engaged in the construction and heavy equipment rental sector, faces challenges in managing and monitoring the availability of heavy equipment, which is still done manually and takes a long time. The process of recapitulating the availability of heavy equipment using lobo reports and manual recording often takes 10 to 60 minutes, with the risk of errors that cause information on the availability of heavy equipment goods to not be provided quickly. In addition, there are errors in creating invoices caused by typing errors by administrative employees when using Microsoft Excel. Therefore, this study aims to design a web-based information system that is able to provide information on the availability of heavy equipment quickly and create invoices automatically. This study uses a system design method using UML and a system interface design method, namely Design Thinking.

Abstract

Advances in information technology provide great opportunities to improve public services, especially in managing public complaints. In Perumahan Nusa Jaya, Kelurahan Sungai Panas, Batam City, which is a community with high social interaction, complaint management is currently still done manually through WhatsApp groups. This approach faces challenges, including lack of focused attention, difficulty tracking complaint status, limited documentation, and lack of transparency. Survey data revealed that most residents consider the current system ineffective and needs innovation. This study proposes the design of a citizen portal web application to streamline the management of complaints and community discussions. This system aims to record complaints periodically, track progress in resolution, provide organized documentation, and increase transparency and accountability for RT/RW administrators. This development follows the Scrum methodology, allows for iterative improvement, and uses the Unified Modeling Language (UML) for process modeling. The interface designed using Figma ensures a user-friendly experience. The proposed application will improve efficiency, transparency, and citizen satisfaction in managing public services in Perumahan Nusa Jaya. By integrating modern technology, this initiative is in line with sustainable development goals, which encourage better community-level governance.

Abstract

Moon Cafe, located at Komplek Penuin Permai Blok B No. 2, faced challenges in menu management and ordering processes. With 94 printed menus, customers often waited their turn, and adding new menus required time and printing costs. The absence of a queue system increased errors, delays, and food waste due to unclear or incorrect orders. This study proposes a web-based ordering system using the Priority Scheduling method to prioritize orders based on cooking time and arrival order. The system, developed with Extreme Programming, ensures flexibility and responsiveness to operational needs. Results show improved efficiency in customer service, reduced recording and serving errors, and streamlined kitchen operations. The web-based system enables quick menu updates without additional costs, while prioritized order management minimizes delays and enhances customer satisfaction. This solution helps optimize Moon Cafe's operations and reduces material losses.

Abstract

Technology is used in the form of business to make decisions in solving problems. One form of utilizing information technology is an expert system. Seeing the many benefits of corn, and the increasing demand for corn production, many farmers are cultivating corn plants which are considered to be a business opportunity for farmers. The source of problems often experienced by farmers is that corn plants are easily attacked by plant diseases which can attack at any time. To overcome and reduce this risk, farmers need to take appropriate action in maintaining these plants. However, currently there is still a lack of knowledge from expert farmers in dealing with disease attacks to determine the appropriate treatment for infected corn plants. As a result of delays in handling, corn farmers often experience significant losses, some even have crop failures. To achieve this goal, a problemsolving method is needed, namely using the forward chaining method, where this method is a search method that obtains accurate results based on known facts which are then matched with existing facts so as to find valid data and lead to a final decision.
