Sebuah Sistem Pencitraan Optik berbasis pada Proyeksi Pola Titik-titik Acak dengan Metode Digital Image Correlation (DIC) untuk Menentukan Profil Kekasaran Permukaan suatu Bahan
Oleh: Karisna, Sasono, Margi, Ardi, Subhan Zul
Reliable methods (techniques) are needed to determine surface roughness accurately. Contact techniques are prevalent but can damage materials and are subject to much noise. Meanwhile, non-contact techniques (usually optical) still face setup complexity and inaccuracy. This paper designs a simple opt...

Generator Set Uji Untuk Diagnosis Kesalahan pada Rangkaian Digital Kombinasional Demultiplexer 1 line to 4 line Menggunakan Metode Tabel Kesalahan
Oleh: Pratama, Denny, Ageng Sadnowo Repelianto, Sri Purwiyanti
Abstract. A small error in the IC can become a big problem if it is not detected and used by the user. Therefore, a fault diagnosis method is needed to ensure the IC functions properly. The method used must be fast and efficient in checking the IC. One method that can be used is designing a test set...
