Abstract

Establishing visitor management system is necessary to manage the total number of visitors especially in pandemic when the protocol of social distancing is applied. The purpose of this research is to design a visitor management system integrated with an automatic Internet of Things (IoT)-based hand sanitizer using Arduino. This research contributes to answering the two challenges which are managing the total number of visitors and providing protection against bacteria or viruses. The improvement of this system compared to the existing similar approach is the automatic hand sanitizers could be installed at two entrances and exits which can simultaneously limit the number of visitors who will be monitored through the IoT platform. This system is designed with Arduino Uno R3 components as a microcontroller, ultrasonic sensors which will be installed at two entrances and exits, and automatic hand sanitizer using a water pump. For remote monitoring use the IoT platform with the ESP8266 ESP-01 Wi-Fi module as a link. From the results of testing this system, the results of testing the correct hand distance when using a hand sanitizer are from 3 cm to 9 cm and the right amount of hand sanitizer liquid volume is approximately 1 ml for a duration of 250 milliseconds. The system design has been successful for visitor management and the hand sanitizer works well. The Thingspeak webserver can receive visitor data and send it to the MIT app as a display for remote monitoring. Hopefully, this system could support the situation which needs to manage the restriction of total number visitors and hygiene practice in a more efficient way.

Abstract

Perkembangan teknologi komputer membuat pengolahan citra saat ini banyak dikembangkan untuk dapat membantu manusia di berbagai bidang pekerjaan. Namun, tidak semua bidang pekerjaan dapat dikembangkan dengan pengolahan citra karena tidak mendukung penggunaan komputer sehingga mendorong pengembangan pengolahan citra dengan mikrokontroler atau mikroprosesor khusus. Perkembangan mikrokontroler dan mikroprosesor memungkinkan pengolahan citra saat ini dapat dikembangkan dengan embedded computer atau single board computer (SBC). Penelitian ini bertujuan untuk menguji kemampuan embedded computer dalam mengolah citra dan membandingkan hasilnya dengan komputer pada umumnya (general purpose computer). Pengujian dilakukan dengan mengukur waktu eksekusi dari empat operasi pengolahan citra yang diberikan pada sepuluh ukuran citra. Hasil yang diperoleh pada penelitian ini menunjukkan bahwa optimasi waktu eksekusi embedded computer lebih baik jika dibandingkan dengan general purpose computer dengan waktu eksekusi rata-rata embedded computer adalah 4-5 kali waktu eksekusi general purpose computer dan ukuran citra maksimal yang tidak membebani CPU terlalu besar untuk embedded computer adalah 256x256 piksel dan untuk general purpose computer adalah 400x300 piksel.

Abstract

Intisari---Suhu merupakan salah satu hal yang sangat berpengaruh terhadap kinerja perangkat keras khususnya  ruang server. Ruang server adalah ruangan yang dapat digunakan untuk menyimpan data, perangkat jaringan dan operasional sistem. Deteksi suhu  ruang server dirancang menggunakan 4 (empat) sensor LM35 yang berfungsi mendeteksi suhu didalam ruang server. Nilai suhu rata-rata ruang server ditampilkan pada LCD. Apabila suhu diruang server  mengalami overheat, maka module GSM SIM900 akan mengirimkan informasi suhu ruang server ke administrator ruang server melalui sms. Perangkat deteksi suhu ruang server terdiri dari rangkaian catu daya, 4 (empat) sensor LM35, Arduino UNO, LCD, relay, kipas angin, module GSM dan handphone. Perangkat ini dapat  monitoring  suhu ruang server dan dapat memberikan informasi apabila suhu ruangan naik. Kipas angin berfungsi menormalkan suhu panas ruang server apabila suhu ruangan naik. Perangkat deteksi suhu pada ruang server ini mampu membantu administrator untuk memonitoring suhu ruang server dari jarak jauh dengan report SMS.Kata kunci--- Arduino Uno, Ruang Server, Sensor Suhu, GSM SIM900 Abstract---Temperature has a very influential impact on the performance of hardware, especially the one which is kept in a server room. The server room is a room that can be used to store data, network devices and operation systems. The detection system of server room’s temperature is designed by using 4 (four) LM35 sensors which functions is to  detect the temperature in the server room. The value of average temperatures in the server room is displayed on the LCD. If the temperature in the server room reachs an overheated degree, the GSM SIM900 module will send the information about the temperature situation in the server room to the server room’s administrator by using an SMS. The server room’s temperature detection device consists of power supply circuits, 4 (four) LM35 sensors, Arduino UNO, LCD, relay, fan, GSM module and mobile phone. This device can monitor the temperature of the server room and can provide information when the room temperature rises. The fan’s function is to normalize the hot temperature in the server room when the room’s temperature rises above a certain degree. Temperature’s detection device in the server room is capable to help administrators to monitor the temperature of the server room remotely using an SMS report.Keywords--- Arduino Uno, Server Space, Temperature  Sensors, GSM SIM900
