In the current era of information technology, easy and efficient transaction management is an important requirement in the business world, both small and large scale. Rumah Makan Mie Happy is a medium-scale culinary business. Happy Noodle Restaurant provides noodle-based preparations. In its daily life, Happy Noodle Restaurant can serve around 100 consumers, so that the service process requires speed to serve consumers. But in fact, Mie Happy Restaurant still uses manual data processing and transaction management, so it often experiences problems such as slow payment processes, frequent loss of receipts or proof of payment, difficulty in recapitulating or reporting transactions both daily and monthly, and frequent errors in the calculation process. From the problems experienced by Mie Happy Restaurant, the author is interested in developing a web-based cashier application that can help in all matters related to transaction management at Mie Happy Restaurant. The research conducted aims to build or develop a cashier application for Happy Noodle Restaurant that can improve the efficiency and effectiveness of transaction management. This cashier application was built or developed using Hypertext Markup Language (HTML) and Hypertext Preprocessor (PHP) with Visual Studio Code editor and MySQL Database Management System (DBMS). The results of testing with black box testing show that the cashier application developed in functionality has run as expected. This web-based cashier application provides convenience for admins and increases the effectiveness and efficiency of operational activities.

In  recent  years,  air  quality  has  become  an  increasingly  important  issue  in  various  cities  around  the  world.  Real-time  air  quality  monitoring  is  essential  for  identifying  pollution  problems  and  taking  appropriate  actions.  This  article  discusses  the  design  of  an  Internet  of  Things  (IoT)-based  air  quality  monitoring  system  using  the  prototype  method.  The  system  is  designed  to  monitor  air  quality  parameters  such  as  PM2.5,  PM10,  CO2,  and  temperature  in  real-time  and  present  the  data  to  users  through  a  web-based  application.

The system for receiving police reports at the Semendawai Tribe III Police is currently still done manually by typing them in Microsoft Word which are then printed and stored in hard copy in the criminal investigation room. Storing files in hard copy form results in files piling up, being scattered, being tucked away, as well as the potential for losing files or having difficulty finding files when they are needed again. Apart from that, police report files in softcopy form are sometimes accidentally deleted, not copied, and immediately overwritten with a new police report, resulting in data loss that cannot be recovered. Therefore, this research aims to design electronic monitoring of police reports using a prototype method that allows gradual development of the system based on input from users. The electronic monitoring design was carried out in several stages, starting with the creation of a report recording module, followed by a combination of report status monitoring features, and ending with the implementation of automatic backup. Each stage is tested and evaluated separately to ensure optimal quality and usability. The research results show that this system is able to increase the efficiency of report management, can minimize the risk of data loss, and makes it easier for Sector Police personnel to monitor the progress of reports. With automatic backup, report data is stored safely and can be accessed at any time. It is hoped that this research can be an innovative solution for Sector Police in digitalizing administrative processes, as well as providing a basis for further development in the future.

This research aims to develop an application for recommending safe and suitable skincare products for pregnant women. The application is built using the prototype method and implemented with the Python programming language using the Flask framework. The study encompasses product categories from Drw Skincare, including serums, toners, shampoos, body care products, facial washes, and creams. The system provides options for users to select categories of skincare ingredients they desire. The application issues warnings about skincare ingredients that should be avoided during pregnancy, such as retinol and specific acids. The end result is a list of recommended skincare products containing ingredients that align with the user's selected criteria. Each product is accompanied by comprehensive information about its ingredients and advice. Users can utilize search and advanced filtering features to find skincare products based on product types and brands. The application offers clear user guidance and an intuitive interface, enabling users to navigate and use the application comfortably. It is expected that this application can assist pregnant women in choosing safe and effective skincare products while providing a better understanding of skincare during pregnancy.

This study focuses on creating a Turnitin tutorial application to track plagiarism using the prototype method approach. The purpose of this application is to make it easier for users to understand and utilize Turnitin as a reliable plagiarism detection tool in academic writing. The prototype method was chosen because it allows for rapid iteration and improvement based on user feedback, which is very important to improve the quality of the application. The development stages include creating an initial prototype, testing functions, and collecting feedback for design refinement. This study aims for the application to be developed to provide clear guidance and effective solutions in identifying and preventing plagiarism, while deepening users' understanding of the use of Turnitin. Thus, this application is expected to strengthen academic integrity and support ethical writing practices through integrated plagiarism detection technology.

The absence of an application to assist in the scheduling of the Communication and Informatics department's duties at TVRI has resulted in ineffective schedule distribution, causing a TVRI staff member to receive two coverage schedules simultaneously, while others may not receive any schedule at all. The purpose of this final report is to create an Application for Coverage, Announcers, and Editorial Schedules at TVRI using the PHP programming language with the Laravel framework and MYSQL database, and designing its interface using Bootstrap. The issue faced by TVRI's Communication and Informatics Department (Diskominfo) is the operational data processing of broadcasting schedules using Microsoft Excel, which poses several challenges including insufficient data security, unorganized data storage making it difficult to search, and the risk of losing previously saved data, thereby slowing down TVRI's reporting process. This application comprises three User levels: admin, User, and TVRI head. The research adopts the Prototype development method to create the Coverage, Announcers, and Editorial Schedule Application at TVRI. Through the Prototype, the development team can quickly visualize the application's design and functionality, gather early User feedback, and address potential issues or design improvements before full implementation. The research outcome, in the form of the application, provides a concrete solution to the challenges of scheduling effectiveness at TVRI, enhancing efficiency, addressing data security concerns, ensuring organized data storage, and improving workflow speed.
