Fire is a threat to human safety, property and the environment. With the increasingly rapid development and progress of development, the risk of fires is increasing. Shophouses or shophouses are places that are prone to fires. The increasingly dense population and the construction of office buildings have created a vulnerability in the event of a fire. Preventive efforts must be carried out by each individual and work unit, so that casualties from fire incidents can be minimized. Fires can cause moral, material and even human life losses. Fires that hit public facilities, of course, cause losses to many people. Shophouse fires often occur suddenly due to short circuits, gas explosions or due to sparks from cigarettes/matches. The research carried out this time focuses on creating a fire detection system using ESP32 and Arduino. The system uses three sensors, namely a temperature sensor, a gas sensor and a fire sensor. Temperature sensors are useful for monitoring room temperature conditions, fire sensors are useful for detecting the presence of fire in a fire disaster and gas sensors are useful for detecting the presence of smoke that appears as a result of a fire disaster. This system uses an ESP32 microcontroller and uses the Arduino IDE application. The results of the fire detection system are expected to reduce the occurrence of fire accidents and also losses caused by fire accidents.

The rapid and easy access to internet technology has also increased the popularity of Muslim fashion. The easier access to the internet, affects the increase in social media users from various socio-economic backgrounds, education levels and ages, as well as the fashion industry which is no longer intended only for certain elites.

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.

The SIKONTRAS application is a web-based application that has previously been used to socialize contraceptives to support government programs in broadcasting family planning programs, however, with technological developments and the large number of user demands who want comfort and ease in accessing information with attractive visuals, especially in terms of system appearance. used, the author took the initiative to carry out an evaluation of the SIKONTRAS application by going through the initial stages, namely distributing questionnaires to SIKONTRAS users and experts in the field of information system development, then from the results of the assessment, they will then be analyzed using the heuristic evaluation method. The research method is heuristic evaluation, method to identify design problems in user interfaces. The evaluator assesses the design based on a set of guidelines (called heuristics) that make the system easy to use.
