Prototype ini mampu melakukan identifikasi data masyarakat serta melakukan pendistribusian bantuan Covid-19 menggunakan prinsip kerja mirip seperti vending machine dengan menggunakan E-KTP sebagai identitas pengguna untuk mengakses alat. RFID digunakan sebagai sensor yang dapat membaca ID pada E-KTP yang sebelumnya telah didaftarkan oleh admin. Sensor ultrasonik HC-SR04 digunakan sebagai pengganti push button, hal ini bertujuan agar tidak terjadinya penyebaran virus Covid-19 akibat sentuhan dari pengguna. Push button digunakan untuk memberikan perintah kepada motor DC untuk bergerak sehingga pintu penghalang otomatis dapat terbuka. Kemampuan RFID membaca ID pada EKTP pada jarak optimal yaitu ≤ 1 cm, sedangkan sensor ultrasonik HC-SR04 dapat digunakan dengan baik dengan akurasi sebesar 98,95%. Prototype ini menggunakan NodeMCU ESP32 sebagai mikrokontroler yang berfungsi untuk mengontrol dan menyimpan data yang telah terbaca oleh RFID. NodeMCU ESP32 mengirimkan data tersebut ke basis data yang kemudian dapat dilihat melalui halaman website.

Jembatan Kuranji terbagi menjadi 2 bagian yaitu jembatan lama yang berusia 30 tahun dan jembatan baru yang berusia 9 tahun. Evaluasi dilakukan dengan menggunakan pengukuran mikrotremor. Pengukuran dilakukan di 12 titik dengan durasi perekaman 90 menit. Hasil pengukuran mikrotremor diolah menggunakan metode Horizontal to Vertical Spectral Ratio (HVSR) dan pergerakan partikel (particle motion) menggunakan Software Geopsy.

Nilai frekuensi alamiah jembatan lama didapatkan sebesar 3,420 Hz dan 2,031 Hz untuk jembatan baru. Nilai rasio frekuensi alamiah jembatan baru sebesar 1,144% dan jembatan lama sebesar 2,611% dan dinyatakan jembatan baru berada dalam keadaan baik secara struktur dan jembatan lama berada dalam keadaan karatan (cacat kecil) yang memerlukan perawatan secara rutin.
