Temperature and humidity are inseparable from server rooms. This is important because server rooms consist of computers that provide services 24 hours a day without stopping. After collecting all the supporting data, the author found that the temperature was too high and the humidity did not meet the standard, causing the computer to not function properly. The author finally created a tool that can monitor the temperature and humidity in the server room and applied it to the server room of Roemani Muhammadiyah Hospital in Semarang. The tool works by reading the temperature and humidity using a DHT22 sensor. After the data is read, the ESP32 will process the data, which will then be sent to a database and stored. The data can be viewed directly from anywhere. The tool not only monitors but also performs other functions, such as turning on the AC/fan when the temperature rises above the predetermined limit and sending notifications via Telegram to the staff so that they can take further action.This device will help the staff because all information about temperature and humidity will be recorded well, so the staff does not need to check the server room all the time.

Indonesia is home to approximately 400 mountains that attract climbers, both local and international. The increasing number of climbers each year correlates with a rise in accidents. According to data from the National Search and Rescue Agency (BASARNAS), climbing accidents have increased over the past four years. In 2018 alone, there were 23 incidents resulting in 6 fatalities, 4 climbers reported missing, 7 climbers fell ill, and 592 climbers were rescued. Human error, such as choosing the wrong route and adverse weather conditions, remains the primary cause of climbers getting lost. To address these challenges, this research develops a GPS and Long Range (LoRa) based mountain climber monitoring system. The system utilizes GPS to track climbers' locations, heart rate sensors to monitor health conditions, and a buzzer for early warnings when climbers enter restricted areas. It also features a panic button for sending SOS signals to rescue posts. Agile Scrum methodology is employed in the system development, enabling iterative and collaborative software development. Research findings indicate that this system enhances efficiency and effectiveness in monitoring and rescuing climbers in distress, thereby improving mountain climbing safety and comfort.

Different types of attendance systems are used in various settings such as schools and companies, namely web-based systems that can be used as a substitute for absenteeism. Another attendance system being developed is a QR Code based attendance system which requires user verification using RFID fingerprint or voice command. It is necessary to develop an attendance system that uses RFID sensors at universities as a technological adaptation.Currently, lecture attendance at the Fakfak State Polytechnic College, especially in the Informatics Management Department, still uses a manual attendance system, namely taking attendance of students using an attendance book every class hour. Running absenteeism creates a problem, namely that it is impractical. The impracticality of this system can be that it takes a lot of time to register students one by one, thereby cutting into course hours. Not to mention the phenomenon of leaving absences which usually takes advantage of lecturers' negligence to sign the absences of friends who are unable to come. You can also directly sign attendance from the first meeting to the last meeting. So the author conducted research on making student attendance tools that use RFID, and can monitor student attendance data by lecturers via a website. Based on these problems, an attendance system based on RFID (Radio Frequency Identification) using NodeMCU is expected to be able to solve these problems.

Sterilization is the eradication of materials, substances, or tools from various live microorganisms or their resting stages. Bacterial and fungal vegetative cells can be killed at a temperature of 60 °C within 5 to 10 minutes. A data logger is a tool used to monitor the temperature inside an autoclave. Previous research on "Autoclave Data Logger" aimed to assist in recording temperature activities within the autoclave. When the device is turned on, it automatically records the temperature inside the autoclave and stores the temperature data read on an SD card. After the sterilization process is completed, the SD card is retrieved for reading on a personal computer in Excel format or converted into a graph. Therefore, the author developed an IoT-based autoclave calibrator tool with data storage. This IoT-based autoclave calibrator tool with data storage utilizes the ESP32 microcontroller for programming and as a source in the IoT system. The ESP32 is used to control the input from the waterproof DS18b20 sensor, which functions to read or detect the temperature in the autoclave. The data read by the sensor will be displayed on the IoT platform, which is the Blynk IoT application, and after the results are displayed on the IoT platform, they will be stored on an SD card.

In the era of maritime technology, Unmanned Surface Vehicles (USVs) are becoming the main vehicles on the water surface, controlled from land and capable of transmitting live data. USVs have a wide range of survey and exploration applications, relying on hydrographic knowledge for accurate mapping. USV development has adopted a double hull design, improving stability and wave resistance. Survey data transmission requires advanced technology, with Long Range (LoRa) technology being the solution for long distance data transmission with low power consumption. LoRa utilisation is expected to increase the efficiency of USVs in hydrographic surveys. The research and development (R&D) research method is used as the main approach in this research with the aim of creating and developing USVs that can increase efficiency in hydrographic surveys. The USV is equipped with an RPM sensor and flowmeter used to monitor the movement control of the USV in the waters. In addition, a depth detector is used to monitor the topography of the seabed. In order for this USV to run using a remote control that is controlled from land. The USV drive consists of a BLDC motor connected to the propeller and a servo motor connected to the ship's rudder. Furthermore, the data taken from the sensor is sent via LoRa to be delivered to the ground station. From the USV test results, it was found that the data transmission range with LoRa Ra-02 under Line of sight (LOS) conditions was 340 metres while under Non Light of sight (NLOS) conditions it was around 200 metres. The average speed travelled by USV is 0.616 km/hour in operational survey conditions and can be faster in non-operational survey conditions. The error value of the RPM sensor is obtained at 1.604% with a reading accuracy of 98.936%.
