Abstrak Perkembangan ilmu pengetahuan dan teknologi semakin maju terutama dibidang teknologi elektro atau teknologi elektronika, banyak keuntungan yang didapatkan akan berkembangnya suatu teknologi namun semakin berkembangnya teknologi makin banyak pula tindak kriminal dan semakin pintar pula pelaku kriminal terutama pada pencurian kendaran. Kita membutuhkan lahan parkir yang aman untuk menyimpan kendaraan kita, peningkatan kemaanan merupakan salah satu yang harus diperhatikan dalam membuat perancangan sistem keamanan parkir. Sistem tersebut diharapkan menurangi tingkat kriminal yang ada disekitar kita. Perancangan sistem parkir ini menggunakan teknologi fingerprint sensor dan Barcode scanner. Bukan hanya sistem keamanan yang di perkuat alat ini pun dapat memberikan informasi data diri dan informasi kendaraan yang di tampilkan pada LCD dengan menggabungkan data sidik jari pengendara. Dengan menggunakan sistem fingerprint yang berkesinambungan dengan barcode scanner diharapkan menekan resiko pencurian kendaraan yang berada pada lingkungan parkir. Metode menyatukan Fingerprint sensor dan barcode scanner yaitu menggunakan mikrokontroler Arduino Wemos D1 R1 yang terkoneksi dengan internet.      Kata Kunci: Parkir, Fingerprint Sensor, Barcode Scanner, Arduino Wemos D1 R1

Security aspects is needed in various fields of life today. Safety is becoming a concern for everyone. One of the important concerns is the security of the room. The indoor security system uses Raspberry Pi and RFID based Firebase Cloud Messaging and Motion Detection Camera, is a room security system that includes expensive equipment, so this device is designed for protection or robbery and also provides assistance in advance. . The security system in this room consists of several parts, namely Raspberry Pi as a brain system, selenoid door lock as an electric lock on the door, RFID system and CCTV camera as a detector of the amount of human movement, PIR sensor as a detector of human temperature, alarm as an indicator of intruders which transfers rooms, and database applications as user storage databases for security recorders  

Data collection on employee attendance at a company is a must, with the aim of monitoring discipline, calculating employee salaries, and other needs. Data collection on employee attendance at companies that are used today is very diverse, following the development of technology. The United Tronik Semarang office, which employs relatively many employees, currently uses a manual card attendance data collection system that attracts researchers to make the United Tronik Office the object of research.  Fingerprint is one of the hardware used to support employee attendance data collection which is relatively simple and easy to reach, the accuracy and ease of operation make the fingerprint attendance system more and more in demand. One of the human error problems in the attendance data collection system is attendance recording errors, especially for employees with shift work hours. Arrangement of work shifts in programs built with Visual Basic 2010 can minimize attendance recording errors, because it can set the recording time for employees. To support the ease of data access and shift settings, the researcher uses a Client Server database system with SQL Server 2005 Software.
