Abstract

Colorectal cancer is one of the leading causes of cancer-related deaths worldwide, with most cases originating from early lesions such as colon polyps. Early detection through colonoscopy is essential to reduce mortality rates; however, accurate polyp identification remains challenging due to variations in shape, size, texture, and illumination conditions. This study aims to implement and evaluate the SegFormer-B0 architecture combined with a Dice-BCE hybrid loss function for polyp segmentation in colonoscopy images. The study utilized the public Kvasir-SEG dataset consisting of 1,000 colonoscopy images with pixel-level annotations. The dataset was divided into 80% training data and 20% validation data. Image preprocessing included resizing to 256×256 pixels and normalization using ImageNet statistics. The model was trained for 25 epochs using the AdamW optimizer with a learning rate of 1×10⁻⁴. Performance evaluation was conducted using Dice Coefficient, Intersection over Union (IoU), Sensitivity, and Specificity metrics. The experimental results demonstrated that the proposed model achieved a Dice Coefficient of 89.92%, Mean IoU of 81.90%, Sensitivity of 89.12%, and Specificity of 98.51%. The training process also showed stable convergence, supported by a training loss of 7.53% and validation loss of 23.30%. The findings indicate that the integration of SegFormer-B0 with the Dice-BCE hybrid loss effectively improves segmentation accuracy and stability while addressing class imbalance issues in colonoscopy images. Therefore, the proposed approach has strong potential to support computer-aided diagnosis systems for colorectal cancer screening.

Abstract

Uji Kompetensi Keahlian (UKK) memastikan penguasaan keterampilan dan pengetahuan pada bidang jaringan LAN. Selain sebagai syarat kelulusan, proses UKK dapat menilai kesiapan dalam memasuki dunia kerja atau melanjutkan pendidikan lebih tinggi. Kegiatan UKK kelas XII jurusan TKJ berlangsung selama 5 hari yang bertempat di Laboratorium Komputer SMK Qamarul Huda. Evaluasi peserta didik dilakukan melalui uji kompetensi untuk mengukur keterampilan dalam konfigurasi jaringan LAN. Pelaksanaan  UKK melibatkan penguji internal yaitu guru produktif dan asesor eksternal sebagai penguji. Instrumen yang digunakan meliputi lembar tugas UKK, rubrik penilain, lembar observasi, serta perangkat peraktek yang mendukung pelaksanaan UKK. Proses evaluasi kompetensi peserta didik SMK Qamarul Huda memiliki tiga tahapan yaitu tahapan pertama persiapan, mempersiapkan perlengkapan dan bahan yang akan digunakan serta mengundang asesor eksternal dari perguruan tinggi. Tahapan kedua yaitu disini peserta didik akan melakukan praktek dengan mengkonfigurasi jaringan komputer LAN agar dapat terkoneksi antara server dan client. Tahapan terakhir yaitu evaluasi, pada tahapan ini asesor melakukan penilaian dengan melihat hasil kerja peserta didik selama mengikuti proses ujian. Peserta didik yang mengikuti UKK berjumlah 90 orang dari jurusan TKJ SMK Qamarul Huda. Hasil evaluasi konfigurasi jaringan LAN bahwa telah diperoleh sebanyak 98% peserta didik dinyatakan sangat kompeten dan 2% dinyatakan kompeten. Kegiatan ini dapat meningkatkan keterampilan praktek serta kesiapan peserta didik dalam menekuni bidang jaringan komputer. Program UKK ini dapat membantu sekolah memastikan ketercapaian kompetensi lulusan peserta didik dalam meghadapi dunia kerja.
