Abstract

AbstractThe floor cleaning tools that we usually use, such as a broom or duster, cause dust to fly which can leave dust in the room. The thing that can be done to overcome this problem is to develop a system that can receive a command to clean the dust, either automatically or manually controlled. This tool is made using the Arduino Uno microcontroller with streaming video using the ESP32-CAM, also HC-SR04 Ultrasonic Sensor and Infrared Sensor as obstacle detectors so that the robot can walk on the floor or table. This research was developed using the Prototyping Method starting from the data collection stage to the system testing stage. The data collection technique is by observing and studying the literature. The test results show that the robot is able to vacuum effectively at speeds of 50-100 with an average effectiveness of 98.27% at speeds of 100 and 83.32% at speeds of 60. Sensor testing of the robot's motion in automatic mode has shown suitability, and the robot can move actively for 25 minutes. Keyword : Arduino Uno, Infrared Sensors, Ultrasonic Sensors, Vacuum Cleaner AbstrakAlat pembersih lantai yang biasa kita gunakan seperti sapu atau kemoceng membuat debu berterbangan yang bisa membuat debu masih tertinggal di ruangan.

Abstract

Papasan Village is located in the Bangsri sub-district, Jepara district. The process of managing mail services in a day serves 20 submissions of letters. This mail service process is still done manually so it takes a relatively long time. Another problem is the potential for document falsification because administrative data reports are not recorded properly, so in this study a population administration service system was developed that utilizes the Quick Response Code (QR Code). System development is carried out using the waterfall method. The system design stage is carried out using Data Flow Diagrams, while the database design is carried out by compiling a Physical Data Model. The QR Code on the letter is scanned through the system to determine the authenticity of the letter. System testing involved 30 respondents consisting of village heads and village residents. The first test using a black box results that the system can run if the data entered is appropriate and the data is not empty. The second test uses the User Acceptance Test (UAT), the total percentage results are 88% or the system is in the very good category. Desa Papasan terletak di kecamatan Bangsri, kabupaten Jepara. Proses pelayanan pengurusan surat dalam sehari melayani 20 pengajuan surat. Proses pelayanan surat ini masih dilakukan secara manual sehingga membutuhkan waktu yang relatif lama. Permasalahan lainnya adalah adanya potensi pemalsuan dokumen karena laporan data administrasi tidak tercatat dengan baik, maka dalam penelitian ini dikembangkan sistem pelayanan administrasi kependudukan yang memanfaatkan Quick Response Code (QR Code). Pengembangan sistem dilakukan dengan menggunakan metode waterfall. Tahap perancangan sistem dilakukan dengan menggunakan Data Flow Diagram, sedangkan perancangan basis data dilakukan dengan menyusun Model Data Fisik. QR Code pada surat dipindai melalui sistem untuk mengetahui keaslian surat. Pengujian sistem melibatkan 30 responden terdiri dari kepala desa dan warga desa. Pengujian pertama menggunakan black box hasilnya sistem dapat berjalan jika data yang dimasukkan sesuai dan data tidak kosong.

Abstract

The dolly camera has function as a regulator of camera movement in making video productions such as films. The movement system on the dolly camera uses the thrust of humans and the running track rail for its movement. The process of preparing the dolly camera also requires a long process, such as assembling the dolly camera and then installing the track, etc. In this case study, we conducted research that designed an electric vehicle to carry a camera but with a simple way of working such as moving without rails and can be controlled with a mobile android. We named this robot vehicle ELDOC: Electric Dolly Camera which uses a four Omni-direction wheels system in the flexibility of direction and motion for taking videos and pictures. Contributions to the design of ELDOC in addition to the multimedia/cinematography field can also be used in the medical field as a monitoring tool for patient activities in isolation or ICU room with a mobile android from different rooms. In the results of the process running on the motor, we take error data from the calculation speed and measurement speed, wherein the duty circle is 19.60%, 38.50%, 58.8%, 78.66%, and the average error is 0,08. The stability level of the ELDOC when carrying the camera is stable but has vibrations or oscillations. The results of the data orientation (gyroscope) show the total average of the three samples Y (Roll) orientation is 0.6°/s and X (Pitch) orientation is 0.18°/s.
