Abstract

Kualitas suatu rangkaian elektronik sangat bergantung pada kualitas Printed Circuit Board (PCB) untuk mendukung proses berjalannya semua komponen. Meskipun dapat menggunakan inspeksi manual terhadap kecacatan pada PCB, namun metode tersebut memiliki keterbatasan terhadap ketelitian dan waktu. Oleh karena itu, penelitian ini dilakukan untuk mengimplementasikan Machine Learning dalam deteksi kecacatan pada PCB. Dalam pengaplikasiannya, penelitian ini menggunakan algoritma deteksi objek YOLOv5 (You Look Only Once versi 5), yang merupakan pengembangan dari convolutional neural network. Fokus penelitian ini adalah membangun sistem yang dapat mengidentifikasi kecacatan pada PCB menggunakan algoritma YOLOv5. Dataset yang digunakan terdiri dari 600 gambar, dengan 480 data latih dan 120 data uji. Jenis kecacatan PCB yang diidentifikasi meliputi open circuit, missing hole, mouse bite, short, spur, dan spurious copper. Hasil penelitian menunjukkan bahwa penggunaan YOLOv5m menghasilkan nilai mean Average Precision (mAP) sebesar 95,3%. Selain itu, dalam pengujian dengan 120 data uji, model berhasil mencapai akurasi sebesar 93,83%, presisi 98,13%, recall 95,43%, dan  error 6,17%.  Selain itu peningkatan spesifikasi hardware juga berpengaruh dalam kecepatan deteksi objek kecacatan pada PCB.Kata kunci : PCB, kecacatan, Machine Learning, convolutional neural network, YOLOv5 The quality of an electronic circuit depends significantly on the quality of the Printed Circuit Board (PCB) supporting its operation.

Abstract

Penelitian ini dimaksudkan untuk mengkaji sejauh mana penerapan metode Drill And Practice berdampak pada pencapaian hasil pembelajaran siswa. pada praktikum Perawatan dan Perbaikan Peralatan Audio Video (P3AV) di kelas 12 Teknik Audio Video SMK Negeri 1 Sumatera Barat. Penelitian ini menerapkan pendekatan kuantitatif dengan metode eksperimen. Dalam penelitian ini, terdapat dua kelompok sampel yang terlibat, yaitu kelas 12 Teknik Audio Video (TAV) sebagai kelompok eksperimen, dan kelas 12 Teknik Elektronika Industri (TEI) sebagai kelompok kontrol. Sampel diambil secara acak sederhana dalam proses pengambilan sampel. Instrumen penelitian yang digunakan mencakup soal pretest dan posttest dalam bentuk objektif serta lembar penilaian praktik yang diberikan setelah proses pembelajaran berakhir. Data penelitian mengindikasikan bahwa kelompok eksperimen memiliki nilai rata-rata sebesar 83,55, melebihi kelompok kontrol yang memiliki rata-rata skor sebesar 75,55. Dari hasil ini Bisa menghasilkan kesimpulan bahwa penerapan metode Drill and Practice berdampak secara relevan pada peningkatan pencapaian belajar siswa sebesar 10,5%. Hasil uji hipotesis menunjukkan bahwa nilai Thitung (3,022) lebih besar dari Ttabel (1,708), sehingga hipotesis (H0) ditolak dan hipotesis (H1) diterima.
