This research aims to establish a reservation system or reservation schedule for health services in the health facility class one. This system uses qr code technology to identify health service schedule orders made by users. This system consists of a laptop webcam that functions as a device for reading data in QR codes, Arduino Uno microcontroller as a data processor for reading QR code results, an MP3 player module as a device for storing sound output, speakers functioning as sound output devices for reading QR codes and Android application as a system interface for ordering health service schedules in health facility class one and accessing databases. Ordering a health service schedule starts with the selection of the service schedule by the user on the android application, then the user will get a qr code as proof of the order made to identify the sequence that will later be read by the webcam laptop and the results processed by Arduino followed by the voice output from the speaker. This study shows the success rate of the system in making online schedule bookings by 100%. In the process of identifying the QR code using a webcam with bright lighting conditions it has a 100% success rate and with a reading range of 11-20 cm a 90% success rate is obtained. In testing, the sound output from the speakers obtained a success rate of 100%.

Security is very important necessary for everyone, one of that security’s needed is the savety of valuables both publicly and more especially at home. Because many of thieves who come direcly to the house, the door was forced open, ande forgot to close the door, the thefs cases increased. Therefore the system can detect movement in front of the door using a PIR sensor design, gives a warning when the door is forced open and can open or close the door automatically. This research uses the Telegram Bot to send orders and receive notifications in the form of text or images. The PIR sensor will give notification when a movement is detected in front of the door, onece detectedit will turn on the LED light and take a picture of the movement, a warning from the system in the form of buzzer. It will also serve as a warning when the door is forced open. When the user enters the open command via Telegram Bot, the door will open and close by itself. The error of the tested system is 0%, all components can work as expected.

This research aims to build a system that can maintain the security of the cage, give feed quail automatically and weigh the weight of the feed by the needs of quail based on the time of eating quail per day. The system consisted of several components, namely fingerprint, SW- 420, buzzer, LED, relay, Arduino Uno, solenoid key, servo, RTC, and Load cell. Access is restricted by examining the authentication through a fingerprint on the fingerprint sensor. If access is granted, then the cage door will open. Otherwise, the door remain close, and if the door is tampered with or opened by force, the SW-420 will automatically detect vibration on the door and turn on the buzzer as a notification. On the part feeding, a separate container-shaped tube as feed storage will be mounted to the motor servo, and the load cell as a tool weighing the weight of the feed is mounted on the container. The servo spin (open) duration is adjusted by the load cell when weighing the feed coming out of the servo with the amount of feed out by the requirements set out in the range of 14-16 gr/session time. Feed that has weighed on the container is ready to be consumed by the quail.

In this study, the detection of falls in wheelchair users aims to make it easier for families to provide assistance when an injury occurs in a wheelchair so that the consequences can be minimized. In this study, the GY-521 sensor was used to detect the tilt of the wheelchair and a pulse sensor to detect the user's pulse. The output of the system in this study is a buzzer and sms notification. If the detected angle is > 25° (pitch angle) and > 30° (roll angle) then it is detected as a fall injury to the wheelchair. And if a small heart rate equals 60 and a large heart rate equals 100 it will be detected as an abnormal heartbeat. In this study, tests for fall detection were carried out on users who have different weights and for heart rate conditions, tests were also carried out when the wheelchair was used or not in use. So it can be concluded that the tilt angle of the wheelchair fall detection system is influenced by the weight of the wheelchair user.

In today's all-digital era, all aspects of supporting human activities are required to make it easier for humans to support human mobility. One example is the scales that are demanded to be sophisticated to facilitate human work considering how busy the trading process is, especially in traditional markets, one example is rice scales which still use manual scales. So from the problems that occur in traditional markets about scales, the researchers will make digital rice scales.The result of this research is the construction of a digital weighing device with a microcontroller-based weight and price output using a weight sensor or load cell. This tool is equipped with 3 types of rice, namely ordinary rice, white glutinous rice, and black glutinous rice. Then it is also equipped with a feature to change the price of rice in the event of a price change. From the results of tests conducted by researchers, this tool functions well and is able to overcome the problems that have been experienced by traders.
