Coal companies in Indonesia each year experience an increase in the amount of production that will be distributed to industries both domestically and abroad. Where some coal companies entrust other companies as contractors in terms of renting heavy equipment units to move overburden or all soil/rock that covers the coal layer. In terms of renting heavy equipment units, the contractor company will calculate the rental cost of the heavy equipment unit when carrying out mining activities by calculating the number of iterations on the heavy equipment unit used. This iteration is the number of heavy equipment work cycles in a certain time unit, sometimes the calculation of the number of iterations has a difference in calculation which results in one party experiencing a loss. Therefore, to overcome the difference in calculation, the researcher created a tool, namely the "Prototype of the Automatic IOT-Based Iteration Calculation Tool on Heavy Equipment Units" so that there is no more difference in the calculation of iterations during the mining process and the productivity of the tool will be in accordance with the planned plan.

Technological innovation always follows user needs and current trends that make it easier for users. One of the applications is in the form of an automatic task receiving and safety device. Automatic task receiving and safety device is an innovative solution that utilizes GM66 sensor, ESP32 module, ESP32 Cam, solenoid, limit switch and Automatic Transfer Switch (ATS). The system allows users to collect tasks or documents through an easily accessible Telegram Bot integration. This tool uses a GM66 sensor that functions to read Quick Response (QR) on the learning module, while the ESP32 functions as the central brain managing and transmitting data through a Wi-Fi network. This tool is also equipped with image capture capabilities using the ESP32 Cam Module. In the security section, this tool is equipped with a solenoid that functions as a mechanical lock on the door, while the switch functions to detect the state of the door on the tool and to ensure smooth operation by switching automatically between the main and backup electrical power sources this tool is equipped with an Automatic Transfer Switch (ATS). This innovation is to improve efficiency, security, and accessibility in the collection of tasks or documents. With IoT, users can easily manage their tasks in real-time with a 90% success rate.

Improving efficiency and quality in ironing and folding clothes is a primary concern in modern households. This research aims to develop a prototype of an automatic ironing and folding device that enhances productivity while reducing processing time compared to manual methods. Testing was conducted on three types of fabric materials: polyester, cotton, and linen, by comparing time and folding quality between the automatic and manual methods. The results showed that the automatic prototype completed the process in an average of 5 minutes for all fabric types, compared to 8 minutes with the manual method. In terms of folding quality, the automatic prototype demonstrated more consistent results with a high level of neatness across all fabric types. The conclusion of this study is that using the automatic ironing and folding prototype provides significant time efficiency and improves quality compared to the manual method. These findings contribute to the development of more effective and efficient household technologies.
