Application of the Internet of Things (IoT) in a home security system based on Esp32-Cam and Telegram to find out what happens in the house when it is empty. This system uses a PIR sensor to detect movement and an ESP32-Cam to take images. The PIR sensor detects movement and the ESP32-Cam will take a picture and send it to Telegram. With this system, it can unite all activities and movements that occur in the house when it is empty. The aim of this research is to determine the process of designing, manufacturing and testing results for the Internet of Things (IoT) in a home security system based on Esp32-Cam and Telegram. The method used in system development is the Prototyping method. The research results show that if there is human movement passing through this tool it will be detected and will send a notification directly to the Telegram application.

Language is an essential tool for communication in human life, including the distinctive Ngapak Javanese Language spoken in the western part of Central Java. Reluctance to use this dialect outside its region leads to a decline in pride and enthusiasm for preserving the culture. Furthermore, language errors often occur, both in terms of politeness and writing conventions. This study aims to develop a web-based sentence pattern error detection system using the Cocke-Younger-Kasami (CYK) Algorithm. The CYK algorithm is chosen for its ability to efficiently analyze sentence structures. The system is designed using HTML, PHP, and CSS to provide user interfaces and server-side processing. The research results show that the system can detect sentence pattern errors with high accuracy, supporting the preservation of the Ngapak Javanese Language and cultural identity through modern technology

The attendance method in the Industry 4.0 era, where the Internet of Things (IoT) is commonly used, is still often carried out manually on paper sheets. This method is considered inefficient and time-consuming. This research aims to develop an attendance method that aligns with the advancements of Industry 4.0 by utilizing IoT technology. The device is designed using the ESP8266 as a development board and RFID as an input sensor. The attendance system is accessed through a website on a local network. The system is stored on a local server and then evaluated through testing of the device and website. The test results show that the overall system built can function properly. The IoT-based attendance system is considered capable of addressing the shortcomings of manual attendance systems by being more accurate, effective, and time-efficient. Additionally, the integration of IoT technology into the attendance system is expected to enhance data security, reduce human error, and enable real-time monitoring. This research is expected to serve as a model for future innovations in attendance systems and can be applied beyond the educational sector.
