Abstract

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.

Abstract

Rabbits have their charm for breeding because of the benefits they get from rabbits. However, rabbit farming has a fairly high challenge, namely rabbits die easily because of the cleanliness of the cage. The accumulation of rabbit droppings results in increased levels of ammonia gas which are harmful to rabbits, breeders, and even the environment. In cleaning the cage, rabbit breeders still use manual methods that are ineffective and inefficient. For this reason, a systemwas created to create an automatic feces cleaning system in the rabbit cage based on IoT (Internet of Things) by utilizing loadcell sensors to detect the weight of rabbit droppings that are accommodated on the conveyor belt. Belt conveyor as a medium that transports rabbit droppings. The MQ-135 sensor is used to detect the concentration of ammonia gas and the MCUESP8266 Node as a controller and IoT as a notification and as a system control via a smartphone. Based on testing of the system, the loadcell sensor as a measure of the weight of rabbit droppings has an accuracy rate of 97.43%. The MQ-135 sensor as a measure of theconcentration of ammonia gas in rabbit cages has an accuracy rate of 99.19%. The conveyor belt can move to dispose of rabbit droppings when the weight is > 1000 grams or the ammonia gas content is > 25 ppm. Then the Telegram application bot can 100% control the system by inputting commands and can receive notifications from the system. From testing the system as a whole, the system can work according to the desired function with a 100% success rate.

Abstract

Parking is an activity to stop or store vehicles in a place that has been provided in public places that have a parking system. The parking system is a system that is applied to a parking environment. Several parking systems developed are manual parking systems, computer-based parking systems, semi-automatic parking systems and RFID-based parking systems. Indonesia has developed a lot of computer-based parking systems, but many areas still use manual parking systems. So that there are still many vehicles parked carelessly, security is not guaranteed and the payment system has not been accumulated based on the length of parking time. This paper describes the development of a parking system based on the template matching method by developing non-cash payments based on the length of parking time. Researchers use a webcam to detect vehicles that will enter the parking area. The captured images are processed in a database to store vehicle entry time information. Researchers use qr codes as a substitute for admission tickets. When leaving the parking area, a QR code will be scanned on the provided application, then users can make payments through the application. This system can be carried out independently by the user so that it does not require full 24-hour supervision.

Abstract

Dalam skripsi ini penulis mencoba membuat suatu sistem pengukur tekanan darah otomatis yang dikontrol melalui aplikasi sehingga dapat digunakan dengan mudah dan efisien. Sistem pengukur tekanan darah otomatis berbasis Internet Of Things ini menggunakan sensor tekanan MPX10DP sebagai pembaca tekanan udara yang dihasilkan oleh motor DC menggunakan mikrokontroler Arduino Uno sebagai pengolah datanya. Proses pengukuran dilakukan dengan manset cuff yang dipasang di lengan pasien, kemudian dipompa sampai pada tekanan udara yang telah ditentukan dan selanjutnya baru dilakukan pengukuran tekanan darah. Perhitungan hasil pengukuran tekanan darah menggunakan rumus Analog Digital Converter. Prinsip kerja sistem ini hampir sama dengan tensimeter pada umumnya, hanya saja proses pengoperasiannya dilakukan secara otomatis dan hasilnya ditampilkan secara digital. Hal yang membedakan sistem ini dengan alat yang sudah ada adalah sistem dikontrol melalui aplikasi, dan pengukuran bisa dilakukan berulang sesuai timer. Sistem ini akan menampilkan keadaan tekanan darah pasien, dan timer untuk melakukan pengukuran berulang. Hasil pengujian sistem pengukur tekanan darah otomatis berbasis IoT ini sudah sesuai dengan tujuan. Sistem yang dibuat dapat digunakan untuk mengukur tekanan darah pada orang remeja,dewasa, hingga lansia. Tekanan yang diukur meliputi tekanan systole. Seluruh hasil pengukuran ditampilkan pada sebuah LCD berukuran 16x2 pada alat, ditampilkan juga pada aplikasi di smartphone android, dan juga pada firebase sebagai media untuk menyimpan data hasil pengukuran pasien, dan untuk input-an timer.
