Abstract

In the current era, coffee shops have become popular destinations for people to unwind while enjoying a variety of food and beverages. Nevertheless, conventional manual ordering systems often result in lengthy queues and operational inefficiencies. To overcome these challenges, this research focuses on developing an Android-based menu ordering application that utilizes QR Code technology combined with the First Come First Serve (FCFS) method. The application aims to streamline the ordering process for customers without requiring staff assistance while enhancing overall workflow efficiency. By employing QR Code technology, customers can view the menu directly on their devices, place orders, and send them digitally to the system. The FCFS method ensures that orders are processed in the sequence they are received, thereby reducing errors in service prioritization. The application was developed using the Waterfall model of the Software Development Life Cycle (SDLC), which encompasses stages such as requirements analysis, design, implementation, and testing. Testing outcomes reveal that the application significantly improves ordering efficiency, decreases waiting times, and increases user satisfaction. By adopting this system, coffee shops can enhance service quality, optimize operations, and provide customers with a more seamless and enjoyable experience.

Abstract

Overstock and delays in fulfilling requests for spare parts at Hyundai Nagoya can occur due to ineffective stock management. The objective of this research is to develop a web-based platform warehousing system that increases the efficiency of goods rotation using the First In First Out (FIFO) method. In addition, the Random Forest algorithm is used to categorize components according to goods movement patterns. The movement patterns of goods are divided into three categories: fast moving, medium moving and slow moving categories. The data analysed includes order history, frequency of use, and stock of goods for the last six months. By implementing a web-based system, real-time stock monitoring and order recommendations based on historical demand patterns can be made. The study's findings demonstrate that the FIFO approach effectively lowers the chance of old products piling up, increasing recording accuracy, and speeding up spare parts distribution. With a classification model accuracy of 75%, this method can improve warehouse management and help make more accurate decisions. In conclusion, the FIFO method can be used in a web-based warehousing system to optimize spare parts stock management at Hyundai Nagoya.

Abstract

Advances in information and communication technology (ICT) have become a key factor in the development of various sectors, including education, industry and government. One of the important components in ICT is computer networks, which are the backbone for delivering data, information and digital services. Computer networks enable devices such as computers, servers, and other devices to communicate with each other, share resources, and access information efficiently. Therefore, mastering knowledge and skills in designing, building and managing computer networks is very important for individuals who want to pursue a career in the field of information technology. However, in some vocational schools that have Computer and Network Engineering majors, there are still students who do not have networking skills that suit the needs of the world of work, so workshops need to be provided so that students can improve their abilities before entering the world of work. The workshop was given over two days using lecture, case study and direct practice methods. Students will be invited to actively participate in each workshop session, so that they can understand the concepts taught better and apply them in real situations. Before the workshop, students were given a pre-test to find out the extent of their knowledge about computer networks. The pre-test results showed that the class average was 72.8. However, there were still some students whose scores were still below 70. During the workshop activities, students were given basic networking material, network topology, simulations with Sisco packet tracer and direct practice in building computer networks. After that, students were given a post-test to determine students' understanding of computer networks. The post-test results showed an increase in students' ability to build networks with a class average score of 83.4

Abstract

The rapid development of technology has brought significant changes to the world of education, particularly in communication and information management. One example is Madrasah Ibtidaiyah Darul Ghufron, located in Batam, which has yet to utilize a website as a digital platform for managing academic and administrative information. Implementing a website in a school environment offers several benefits, including making information more accessible to the public, simplifying administrative processes such as new student registration, and reducing reliance on physical documents. The unavailability of a website causes the New Student Admission (PPDB) process to remain conventional, leading to delays in announcements and the risk of physical document damage or loss. This study aims to design and develop a school website with an online PPDB feature that can be accessed by prospective students, parents, and the general public. The website is designed using the waterfall system development method, which includes requirements analysis, design, implementation, testing, and maintenance stages. System testing is conducted through black box testing to ensure the website’s functionality meets user expectations. The study’s results indicate that this school website facilitates new student registration, provides broad access to school information, and assists teachers in managing applicant data, from registration to selection announcements. This website is expected to enhance efficiency and effectiveness in school data management and address the public's need for accessible information.
