The world has entered the era of industrial revolution 4.0. The Internet of Things continues to be developed to support the industrial revolution and the utilization of more appropriate technology to help human work. IoT-based baby incubator temperature and humidity monitoring system with the ultimate goal of producing a research that in the future can be developed as a viable system for medical purposes. The system is designed as a prototype and props by utilizing the DHT11 sensor as well as relay output modules, buzzers, and lights. Raspberry Pi acts as a data processor that receives data from the sensor and then stores it in the database that has been embedded in it. The database can be displayed in real-time on a web page designed for all devices. The lamp as a temperature guard props is automatically controlled and the buzzer module as an alarm if the system is not connected to the network. The final goal of this research is to produce a simple monitoring product that can record baby incubator data and the data can be developed as an analysis by medical staff later by utilizing IoT and machine learning.

Indonesia prefers social distancing as a solution to implementing lockdowns, namely locking access to entry and exit of areas for anyone to prevent the spread of the virus which is generally used by most countries. The essence of social restrictions is to stay away from direct social activities with other people, while a lockdown means an area will be isolated and all activities in that area will be completely stopped. The basic reason why Indonesia prefers to impose social restrictions is because many Indonesian people rely on daily wages, so they are prone to not being able to make a living if the lockdown is enforced. Maintaining social distance at least imposes several appeals to all residents, including working from home, studying from home, and worshiping at home. During the Covid 19 pandemic that we are currently experiencing, various technological innovations were created as the first step in breaking the chain of the spread of the corona virus. One way to break the chain of the Covid-19 pandemic, especially in public areas, is to spray disinfectant liquid which can be done continuously. Optimization of spraying disinfectant liquid can be done by utilizing technology that can work automatically. This research makes the disinfectant spray booth a technological innovation. Automating the disinfectant sprayer can be carried out by utilizing the ATemega328 micro-controller as an automatic machine to activate the sprayer pump based on the detection of surrounding objects with the help of ultrasonic sensors. Determining the reading distance of the object greatly determines the performance of the ultrasonic sensor in providing input to the microcontroller. The intelligent sprayer system can activate a 12Volt DC pump with a voltage of 5 amperes. This innovative sprayer disinfectant control system can be applied to gates or aisles in a crowd.

According to the World Health Organization (WHO) Corona Virus Disease 2019 or commonly abbreviated as COVID-19 is an infectious disease caused by SARS-CoV-2, a type of coronavirus. People with COVID-19 can experience fever, dry cough and difficulty breathing. Corona disease transmission spreads very quickly and is quite deadly. One of the possible symptoms of Covid-19 is an abnormal body temperature above 38 C. Because of these problems, this paper discusses touchless infrared-based automatic body temperature measuring devices to measure the measured human body temperature. Which can measure human body temperature at a distance of 15cm. This body temperature measuring device uses an ATMega16 microcontroller. Designed to facilitate the automatic detection of body temperature without human assistance. For the temperature sensor, we use the GY-906 MLX90614 sensor module to measure temperature without touch with a maximum distance of 10cm and a laser module as a marker. To display the temperature, a 16x2 LCD and LED lights are used as markers. Then the writer makes the spacing. If there is no object within 10 cm of the temperature sensor, the sensor will turn off automatically with the HCSR -04 infrared module. The design of this tool is the best solution to overcome problems in measuring body temperature in the current pandemic era. Automatic body temperature measurement is undoubtedly better than manual body temperature measurement. Moreover, of course, it will minimize contact, which is a form of virus transmission.

In prior research, a microcontroller-assisted SMS gateway was used to create a system for light control. This makes it unnecessary to push the light switch on the wall to control the lights in the house. In tandem with technical advancements, the Raspberry Pi 3, often known as a mini-PC, has been created as a controller device (PC). In this study, the Raspberry Pi 3 was utilized to deploy the Raspbian Jessie operating system on the light control system, and the action research methodology was employed to generate research results that were consistent with the study's aims. In order to execute the user interface of the Raspberry Pi 3 based lamp control system, the Python programming language is also required. For testing the lighting control system, an E10-fitted incandescent flashlight and an E27-fitted incandescent household lamp were employed. Based on the results of this study, a Raspberry Pi 3 with Raspbian Jessie and a relay module can be used to easily and effectively turn on and off household incandescent bulbs (fitting type E27) using a web-based user interface.
