Abstract

Penguasaan keterampilan menulis artikel ilmiah populer menjadi salah satu bentuk penguatan literasi yang penting bagi guru Bahasa Indonesia. Namun, tidak sedikit guru yang mengalami kendala dalam memahami struktur, gaya bahasa, serta teknik publikasi artikel populer. Kegiatan pengabdian ini bertujuan untuk meningkatkan kompetensi guru dalam menulis artikel ilmiah populer melalui pelatihan dan pendampingan yang diberikan kepada anggota MGMP Bahasa Indonesia Kabupaten Kudus. Metode pelaksanaan kegiatan meliputi tahap persiapan, pelatihan, dan pendampingan individu. Pelatihan dilakukan secara partisipatif melalui kombinasi sesi materi dan praktik langsung. Hasil kegiatan menunjukkan adanya peningkatan signifikan dalam pemahaman peserta terhadap materi kepenulisan, yang ditunjukkan melalui banyaknya artikel yang berhasil disusun, serta siap untuk dipublikasikan di platform online. Hasil evaluasi juga menunjukkan bahwa mayoritas peserta merasa puas dengan pelaksanaan kegiatan ini. Pelatihan ini terbukti efektif dalam meningkatkan kompetensi literasi guru, serta dapat direplikasi dalam skala lebih luas untuk mendukung budaya literasi dan publikasi di kalangan pendidik.

Abstract

Online gambling (judol) spam comments on Indonesian YouTube are disguised using obfuscated text techniques, substituting non-standard Unicode characters designed to bypass string-matching moderation systems. Vocabulary-based Natural Language Processing (NLP) models such as IndoBERT risk representation degradation as tokenizers map non-standard characters to unknown ([UNK]) tokens. This study implemented a hybrid model using a Dual-Track Preprocessing architecture combining IndoBERT [CLS] vectors from normalized text with TF-IDF character N-Gram LinearSVC features from raw Unicode text via sparse matrix concatenation. Experiments on 6,000 YouTube judol comments show the hybrid model achieving Accuracy=0.9978, Precision=0.9956, Recall=1.0000, F1-Score=0.9978 on the test set, identical to standalone IndoBERT and outperforming standalone LinearSVC (F1=0.9944). The hybrid model preserved IndoBERT peak performance while fully closing the 4-comment obfuscated-spam gap missed by LinearSVC, with no performance penalty from fusion. Keywords: Character N-Gram; Gambling Spam Detection; Hybrid Model; IndoBERT; LinearSVC Abstrak Komentar spam judi online (judol) di YouTube Indonesia disamarkan menggunakan teknik obfuscated text, yakni substitusi karakter Unicode non-standar yang dirancang untuk menghindari sistem moderasi berbasis pencocokan string. Model Natural Language Processing (NLP) berbasis kosakata seperti IndoBERT berisiko mengalami degradasi representasi karena tokenizer memetakan karakter non-standar ke token tidak dikenal ([UNK]). Penelitian ini mengimplementasikan model hybrid dengan arsitektur Dual-Track Preprocessing yang menggabungkan vektor [CLS] IndoBERT dari teks ternormalisasi dan fitur TF-IDF karakter N-Gram LinearSVC dari teks Unicode mentah melalui konkatenasi sparse matrix. Eksperimen pada 6.000 sampel komentar judol YouTube menunjukkan model hybrid mencapai Accuracy=0,9978, Precision=0,9956, Recall=1,0000, F1-Score=0,9978 pada test set, identik dengan IndoBERT standalone dan unggul atas LinearSVC standalone (F1=0,9944). Model hybrid mempertahankan kinerja puncak IndoBERT sekaligus menutup seluruh celah 4 komentar obfuscated yang terlewat oleh LinearSVC, tanpa penalti performa dari proses fusi.

Abstract

Image improvement is the process to improve visual quality, from the original image to get optimal image results. The first category, this technique operates on the transformation of frequency selection and the second technique operates directly at the pixel level of the image. in this study the Exposure Sub-Image Histogram Equalization (ESIHE) technique will be enhanced with a brightness level to get visual image results. Then ESIHE is compared with other additional techniques, such as Histogram Equalization (HE), Adaptive Histogram Equalization (AHE) from the side of the image. Furthermore, for the even distribution of histograms, we will use ESIHE entropy calculations to show an increase in the image results that are more optimal when compared with HE and AHE. The visual image quality of each technique shows the strength of the method and the superiority of the other methods for various types of images.
