Furniture has high added value and significant global competitiveness, largely due to the diversity of natural raw materials available in Indonesia, such as wood, rattan, and bamboo, as well as distinctive and high-quality designs. This advantage is supported by the skills and competence of the available human resources, making Indonesian furniture superior to products from other countries. Product quality is a key element in winning market competition, as it impacts customer satisfaction and loyalty. Masnur Joglo, a furniture company located on Jl. Muara Karya, specializes in producing various types of furniture from high-quality woods such as super mahogany and red teak. However, the purchasing system, which requires customers to visit the store directly and manually record prices, results in inefficiencies in terms of time and transportation costs. Customers often need to visit multiple stores to find the desired product, which is an inefficient process. To address these challenges, this study proposes the development of an Android-based sales application as a solution. This application is designed to expand Masnur Joglo's market reach and facilitate online ordering of furniture products, anytime and anywhere. The study aims to design and develop an Android-based sales information system that can enhance operational efficiency and streamline the sales process while better meeting customer needs. The application development method employs the waterfall model and uses MySQL and Firebase databases.

The business of selling coffee in the world is growing more easily and quickly with the provision of a place which is usually called a cafe or shop. One of them is the Titik Hitam Nalar cafe in Jakarta, but the ordering process with customers takes longer to wait for orders and customer payments that are not neatly arranged create conditions that’s are not conducive, resulting in continuous negative criticism. Therefore, an application is needed that helps employees work in every part, both in terms of ordering, manufacturing, and payments, using the FIFO algorithm which focuses on which services are prioritized first in order to reduce negative sentiment from customers. The Android-based application was created by involving every design phase, making it easier for customers and employees to provide a service facility that works well and is suitable for use.  

Technological progress is currently felt to be increasingly rapid, we can feel that progress in the field of technology is greatly influencing our daily lives. The digital economy is a form of technological development that is currently being enjoyed by various groups, including children, teenagers and adults. This digital economy is an economic activity carried out with the help of digital technology. One form of digital economic technology is the internet, Android-based cellphones/applications. Since Covid-19 happened, it has forced everyone to use gadgets to carry out all their activities, especially children from elementary school to university level, as well as TPQ children at the Nurul Ihsan Mosque when carrying out learning activities, they have to use gadgets to be able to carry out activities. from their respective homes with the aim of not gathering in one place (mosque). The use of digital economic technology is able to influence them, such as in the games and applications available. Basically, the use of this technology still has to be supervised by parents, but not all parents can monitor their children's use of this item so that even in our daily lives, the use of digital economic technology can influence the attitudes and ethics of children and teenagers.

The background of this research is the lack of interest of Dhyana Pura University Informatics Engineering Study Program students in visiting the library. This shows the need for a new innovation in the library that can increase the attractiveness of students to visit the library more often.

The success of the Navy's main tasks is greatly determined by the availability of materials, so it can be said that the Indonesian Navy is an army of heavy materials (heavy materials). Therefore, the materials of the Indonesian Navy are operational tools and equipment that also determine the success of an operation of a warship (KRI). To ensure that these materials are ready for use and maintenance throughout their lifespan, maintenance is necessary. Logistic support, which includes supply support, is an element that also determines the final outcome of each operation carried out. The PUT (Penerima Untuk Terima) procedure for requesting supplies can be easily implemented using an application built with hardware, software, and supporting components. The hardware serves as a crucial component for running software developers and *apk on devices. Software acts as a command in programming languages, executing various commands. The supporting component is physical warehouse data when requesting supplies, which gives software XAMPP commands within the hardware. Therefore, it is necessary to have sufficient supporting software that can be installed on a computer, requiring additional internet costs to open the warehouse management system application. Additionally, it is also necessary to have experts who understand online warehouse systems and job adjustments that were originally performed manually to be computerized. The research results show that the use of a computer-based lesson supply control system with Android technology as the medium for lesson supply requests is quite good and easy to manage in terms of distribution and management of each lesson supply request. With the lesson supply system, timely accuracy during PUT (Penerima Untuk Terima) is beneficial for Subdismatbek, warehouses, and Kadeplog in using lesson supplies. The application still requires constructive suggestions for improvement in the future.  

This study aims to identify the problems faced by students in implementing learning. This study used a quantitative approach with a survey method, involving 30 students from two high schools in Yogyakarta. Data were collected through questionnaires about students' learning difficulties, interests, and needs for learning media. The results showed that 96% of the students considered chemistry as a difficult subject to understand because of the abstract nature of the material. As many as 64% of the students felt bored due to the uninteresting presentation of the material, while 72% of the students indicated the need for varied learning methods and interactive learning media to facilitate understanding. The results of the study showed that an innovation was needed to support chemistry learning activities to make learning more active and enjoyable so that it does not lead to student boredom. The developed virtual laboratory media provides flexible, safe and economical simulation of chemical experiments. This application is designed to be accessible without an internet connection using an Android device, allowing students to learn anytime and anywhere. The use of this virtual lab is expected to increase students' motivation, understanding of concepts, and learning experience.
