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

PT. Biru Semesata Abadi is a company engaged in refill drinking water, one of the many drinking water companies in Semarang, and has many branches (10 branches) and one head office in Semarang (in the Bugangan area, East Semarang district), because this company has franchise system. In this case, I will discuss the presence system (presence) of employees of PT. Biru Semesta Abadi, Fatmawati Semarang branch which is still manual (presence made of paper and written by hand) and still encounters many obstacles. This desire arises because this company has difficulties in processing Presence information data, resulting in more and more hardcopy archives and makes it difficult when the company management intends to recap and re-collect data and employee attendance lists. Presence Process that already exists in the Study of PT. Blue Semesta Abadi Semarang can be said that there are still shortcomings because everything is still done manuallyThe use of the Fingerprint method in this employee Presence system application will also make this Presence system more effective and efficient because each employee will only paste one of the employee's fingerprints on the available Fingerprint device where the calculation of the employee's attendance and exit hours will be entered in the database. , then the result of inputting the employee identification number will be the reference for the employee's arrival time.

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.

Attendance is important for an agency or company. because it is used in calculating the salary or wages of an employee and from absenteeism can also see the discipline of employee attendance. Therefore, in the implementation of the attendance process it is very necessary accuracy in its implementation so as not to hamper the company's performance.This final project designs an employee attendance system at CV. INNOVATION MEDIA that is useful to provide good absentee information quickly and easily, also through this study is expected to provide convenience to employees of CV. INNOVATION MEDIA in attendance. The design of employee attendance systems at CV. This INNOVATION MEDIA was developed using Visual Basic 6.0 software and with Finger Print as a tool. This system records employee attendance in the form of a daily attendance list. It is used to store data - data needed to expedite the information system.With this system the data processing is expected to be more effective and efficient. Even searching for data will be easier. The purpose of this research is to design an employee attendance information system that is expected to help the company's performance especially in the Human Resources Field to be faster and more practical.

Sidik jari manusia ini merupakan bukti materi yang amat penting. Akurasi dalam melakukanidentifikasi bergantung pada reliabilitas ciri yang diambil dari citra sidik jari. Pada penelitian ini untukmenghasilkan ciri-ciri sidik jari digunakan metode pendekatan karakteristik fraktal. Pendekatan fraktaldipilih didasari pada pertimbangan bahwa struktur garis-garis sidik jari bersifat alami dan tidak teratur, danfraktal dikenal sebagai metode yang sangat cocok untuk keadaan alami dan tidak teratur tersebut. Adapuntahapan dalam mengolah data sidik jari  pada penelitian ini adalah akuisisi citra, preprocessing, ekstraksiciri, dan pencocokan. Akuisisi citra adalah tahap yang diawali dengan menangkap / mengambil gambarsidik jari dengan menggunakan scanner. Citra sidik jari yang diolah adalah citra grayscale dengan 256tingkat keabuan dan memiliki dimensi 320 x 320 pixel, dengan kerapatan gambar 300 dpi. Tahapanpreprocessing meliputi beberapa tahapan yaitu: normalisasi orientasi, segmentasi, perbaikan citra(enhancement), ekstraksi bukit dan penipisan. Ekstraksi ciri merupakan proses untuk menghasilkan cirisidik jari, yaitu dengan menggunakan metode fraktal (kode fraktal, dimensi fraktal dan derajatkekosongan). Pencocokan adalah proses untuk identifikasi sidik jari. Sistem pengolahan citra sidik jariyang telah dibuat untuk mendapatkan ekstraksi ciri ini telah dapat menentukan hasil identifikasi sidik jaridengan menghasilkan tiga ciri fraktal yaitu kode fraktal, dimensi fraktal dan derajat kekosongan.
