Dalam situasi pandemi Covid-19, roda perekonomian harus tetap berjalan dengan mengedepankan protokol kesehatan. Melansir dari keputusan menteri kesehatan bahwa setiap kantor di Indonesia yang tetap melaksakan Work From Office selama PSBB berlangsung maka harus melakukan pengukuran suhu tubuh, menyediakan hand sanitizer dengan konsentrasi alkohol minimal 70% atau menyediakan sarana cuci tangan di depan pintu masuk. Masalah yang sering terjadi adalah pengukuran suhu tubuh masih dilakukan secara manual oleh satpam kantor, dan tidak terbiasanya para karyawan untuk menggunakan hand sanitizer. Sebagai upaya pendisiplinan karyawan, maka dirancang prototype pintu otomatis yang hanya bisa terbuka jika suhu tubuh normal dan karyawan sudah menggunakan hand sanitizer. Deteksi suhu tubuh dilakukan menggunakan sensor suhu MLX90614 dan deteksi objek tangan menggunakan sensor infrared. Pintu geser digerakkan oleh Stepper Motor NEMA 17, pintu secara otomatis akan terbuka ketika suhu terdeteksi normal, jika tidak maka buzzer akan berbunyi dan pintu tetap tertutup. Hasil dari penelitian ini memperoleh hasil pengujian keakuratan sensor suhu MLX90614 sebesar 96.8%, posisi tangan optimal yaitu posisi tangan menengadah dengan jarak 1cm terhadap sensor, dan volume hand sanitizer yang cukup untuk mengcover seluruh telapak tangan dewasa adalah pada delay 500 ms yaitu sebesar 2.2991 gram. During the Covid-19 pandemic, the economics activities must go on with strict health protocols. From the recommendation of health ministry, that every office in Indonesia that still performs Work From Office during the pandemic, temperature measurements must be carried out at the entrance to the office and hand sanitizer that contains minimum of 70% alcohol or hand washing facilities must be provided as well. The problem is that body temperature measurements are still done manually by security officer, and some employees are still not familiar to use hand sanitizer periodically. As an option to make employees discipline, a prototype of automatic door is designed in this research. It can only open if the body temperature of employee is normal and the employee has used hand sanitizer. Body temperature detection is carried out by using the MLX90614 temperature sensor and hand object detection will utilize infrared sensor. The sliding door is driven by the NEMA 17 Stepper Motor, the door will automatically open when the temperature is detected normally, otherwise the buzzer will sound and the door will be still closed. From the testing results in this research, the accuracy of the MLX90614 temperature sensor is 96.8%, the optimal position of the hand is 1 cm from the sensor with looking up position. And the volume of the hand sanitizer that is sufficient to cover all adult palms with 500 ms delay is 2.2991 grams.
