Abstract

Proses pengenalan objek dalam citra umumnya membutuhkan suatu ciri yang dapat membedakan antara objek satu dengan objek yang lainnya dan bentuk dari sel darah. Ciri yang dapat diekstraksi diantara lain ciri ukuran (luasan dan keliling) dan posisi (koordinat sentroid) dari suatu objek. Sentroid merupakan koordinat titik tengah dari suatu objek, luasan merupakan banyaknya piksel yang menyusun pada objek. Sedangkan keliling merupakan banyaknya piksel yang berada pada objek batas. Ketiga sel darah tersebut memiliki bentuk yang berbeda. Eritrosit memiliki bentuk pipih seperti cakram bikonkaf dengan diameter 7,5 µm memiliki ketebalan 2 µm dan tidak berinti, sedangkan untuk leukosit mempunyai satu inti sel dan berbentuk tidak tetap memiliki ukuran 8-15 µm. Keping darah memiliki ciri dan bentuk yang berbeda dari eritrosit dan leukosit, trombosit memiliki yang paling terkecil berukuran 2 µm memiliki bentuk tidak beraturan salah satunya berbentuk lonjong, trombosit terdiri dari kepingan-kepingan darah yang memiliki Nukleus. Dari hasil pengenalan tersebut maka akan diketahui sebuah ciri tersendiri diantaranya dalam tahapan pengenalan pola, operasi morfologi disini digunakan untuk pengenalan bentuk dari sebuah objek dan dapat diberi label berdasarkan bentuk dan ukuran.

Abstract

The Traveling Band Screen (TBS) is a means of filtering trash and sea creatures such as jellyfish in the PLTU Intake area. FFB filters waste by rotating the screen, then the waste is sprayed using backwash water so that the filtered waste can fall into the disposal route. The amount of impurity material stuck on the screen has an impact on the decrease in flow capacity, thus affecting the increase in the load of the TBS motor and causing the TBS to become overloaded so that the PLTU will Shut Down, so an analysis is needed to determine the electric ability of the motor drive of the TBS system to block the screen. One of the analyzes carried out is observing the optimal load of the motor with power: 2/1 HP, Rotation: 1500 rpm with reduction ratio: 1500: 1 to determine the load blockage by using the SEW Eurodrive motor manufacturer. From the results of the load analysis, the existing motor specifications are only able to operate for a screen clogging percentage of less than 13.6%.

Abstract

In the current era of Industry 4.0, technological and robotics advancements are proceeding rapidly, particularly in the fields of science, technology, and mathematics; however, knowledge and literacy among high school students regarding the identification and use of robotic components remain very limited. An introductory training session on transporter robot components was conducted for students at SMA Kesatrian 2 Semarang with the aim of enhancing their understanding of robotics fundamentals. The activity involved the presentation of material, demonstrations, and hands-on practice in identifying the parts of a transporter robot. Assessment was carried out using pre-tests and post-tests administered to 20 participants. The results demonstrated a significant improvement in understanding across all areas, including robot components, power sources, drive systems, control systems, and the functions of the transporter robot. The average percentage of correct answers rose from 24% in the pre-test to 85% in the post-test. These results indicate that the training successfully improved student understanding and fostered greater interest in robotics technology.
