Abstract

Aktivitas pemantauan berita di Humas PTPN IV Regional III masih dilakukan secara manual sehingga memerlukan waktu yang lama, rentan terhadap subjektivitas, dan berisiko melewatkan informasi penting. Penelitian ini bertujuan untuk merancang dan membangun sistem pemantauan berita berbasis web yang mengintegrasikan model Indonesian Bidirectional Encoder Representations from Transformers (IndoBERT) untuk klasifikasi sentimen secara otomatis. IndoBERT dipilih karena dilatih khusus menggunakan korpus berbahasa Indonesia sehingga lebih mampu memahami karakteristik bahasa dan sentimen dibandingkan model multilingual. Dataset yang digunakan terdiri atas 1.200 berita dengan distribusi seimbang pada tiga kelas sentimen: positif, netral, dan negatif. Model dikembangkan menggunakan metode fine-tuning dan menghasilkan akurasi 75% serta macro F1-score 0,74. Kelas negatif memperoleh kinerja terbaik dengan F1-score 0,85, sedangkan kelas netral mencapai 0,63 akibat karakteristik sentimen yang ambigu. Sistem ini dikembangkan menggunakan Flask, Next.js, MySQL, dan SerpAPI. Hasil pengujian Black Box menunjukkan bahwa seluruh fitur berfungsi sesuai kebutuhan, sedangkan User Acceptance Testing (UAT) memperoleh tingkat penerimaan sebesar 96,5%. Penelitian ini berkontribusi melalui implementasi sistem pemantauan berita korporasi berbasis web yang mengintegrasikan IndoBERT secara end-to-end.

Abstract

Pengelolaan parkir secara konvensional masih memiliki keterbatasan dalam pemantauan kendaraan, pengendalian akses, dan pencatatan data secara terstruktur. Sistem dirancang untuk menangkap citra objek melalui ESP32-CAM, memproses deteksi motor menggunakan YOLOv3 pada Python, mengendalikan portal melalui motor servo, menyalakan lampu kilat pada kondisi tertentu, serta menyimpan data hasil deteksi ke basis data MySQL. Pengujian sistem dilakukan pada area parkir Lapangan Borasi, Manokwari, Papua Barat. Kontribusi penelitian ini terletak pada integrasi deteksi kendaraan roda dua berbasis YOLOv3 dengan sistem kontrol portal otomatis, pencahayaan adaptif menggunakan flash ESP32-CAM, serta penyimpanan data deteksi secara real-time ke basis data MySQL dalam satu sistem IoT yang terintegrasi. Pengujian dilakukan menggunakan 19 data uji yang terdiri atas 15 motor dan 4 objek bukan motor. Hasil pengujian menunjukkan bahwa 13 motor berhasil terdeteksi, sedangkan 2 motor tidak terdeteksi pada malam hari akibat rendahnya pencahayaan. Pada objek bukan motor, 2 mobil dan 1 orang berhasil dikenali sebagai bukan motor, sedangkan 1 sepeda salah terdeteksi sebagai motor. Berdasarkan confusion matrix, sistem memperoleh akurasi sebesar 84,21%, presisi motor sebesar 92,86%, dan recall sebesar 86,67%. Hasil ini menunjukkan bahwa sistem mampu melakukan deteksi motor dan pengendalian portal secara otomatis, meskipun masih dipengaruhi oleh kondisi pencahayaan dan kemiripan bentuk objek.
Klasifikasi Hate Speech dan Offensive Language Menggunakan Hybrid RoBERTa dan XGBoost dengan Optimasi Hyperparameter: Hate Speech and Offensive Language Classification Using Hybrid RoBERTa and XGBoost with Hyperparameter Optimization Jauhari, Najwa; Agustian, Surya; Syafria, Fadhilah; Affandes, Muhammad

Abstract

Ujaran kebencian dan bahasa ofensif di media sosial merupakan masalah serius yang membutuhkan deteksi otomatis yang akurat. Penelitian ini mengusulkan pendekatan hybrid yang menggabungkan model Robustly Optimised BERT Approach (RoBERTa) berbasis Twitter (cardiffnlp/twitter?roberta?base?offensive) sebagai ekstraktor fitur dengan algoritma XGBoost untuk klasifikasi pada dataset Hate Speech and Offensive Content Identification (HASOC) 2021 berbahasa Inggris. Kebaruan penelitian ini terletak pada integrasi optimasi hyperparameter Optuna, Multi?Seed Ensemble, Division Calibration, dan oversampling pada ruang fitur embedding yang belum pernah diterapkan secara bersamaan dalam satu pipeline pada HASOC 2021. Dua tugas diselesaikan : Task 1A adalah klasifikasi biner untuk membedakan konten Hate and Offensive (HOF) dari yang tidak (NOT). Task 1B adalah klasifikasi multi-kelas yang membagi tweet menjadi empat kategori: (ujaran kebencian terhadap kelompok) HATE, bahasa ofensif terhadap individu (OFFN), kata kasar tanpa target spesifik (PRFN), dan konten aman (NONE).  Ketidakseimbangan kelas ditangani dengan oversampling pada ruang fitur, dan optimasi hyperparameter dilakukan untuk meningkatkan performa. Hasil evaluasi pada data uji menunjukkan Macro F1?Score sebesar 0,8083 untuk Task 1A dan 0,6541 untuk Task 1B. Perbandingan dengan papan peringkat HASOC 2021 menunjukkan bahwa skor tersebut sebanding dengan tim peringkat 5 (Task 1A) dan peringkat 3 (Task 1B) yang berbasis BERT murni.

Abstract

Communication barriers between deaf and hearing individuals remain a major challenge in inclusive education and social interaction. Most Indonesian Sign Language (Sistem Isyarat Bahasa Indonesia = SIBI) recognition systems focus solely on isolated gesture classification, without contextual understanding. This study proposes a real-time SIBI recognition system integrating LSTM-based temporal modeling and IndoBERT contextual language modeling. Hand keypoints were extracted from gesture sequences and processed using Long Short-Term Memory (LSTM) to recognize dynamic alphabet gestures. The predicted letter sequences were refined using a Trie-based lexical filter and IndoBERT to generate contextually appropriate word predictions. The dataset consisted of 780 gesture sequences representing 26 alphabet classes. The results showed that the system achieved 89.42% accuracy, 91.57% precision, 89.42% recall, and 88.74% F1-score while maintaining real-time performance at an average processing speed of 249.18 FPS and a latency of 129.46 ms per sample. Statistical evaluation confirmed that camera distance significantly affected recognition performance, while integrating IndoBERT improved contextual word-prediction accuracy from 18.2% to 58.64% (3.2× improvement). McNemar analysis further verified that the improvement was statistically significant, highlighting the effectiveness of contextual language modeling for enhancing semantic interpretation SIBI recognition. The proposed framework improves semantic interpretation and real-time usability for SIBI-based assistive communication systems.

Abstract

Hadith is the second primary source of Islamic law. This study aims to classify the translations of Sahih al-Bukhari Hadith into three thematic categories simultaneously, namely recommendations, prohibitions, and information, using a multi-label classification approach with the Backpropagation Neural Network (BPNN) method. The dataset consists of 7,000 labeled instances. The preprocessing stage includes case folding and text cleaning without stopword removal or stemming to preserve the original meaning of the text. The novelty of this study lies in the comprehensive exploration of various model configurations, including variations in hidden layer architecture, learning rate values, and n-gram features, to identify the optimal network architecture. Feature extraction was performed using Term Frequency–Inverse Document Frequency (TF-IDF) with n-gram configurations of (1,1) and (1,2) and a maximum of 7,000 features. Three variations of the BPNN architecture (H1, H2, and H3) were evaluated using 10-fold cross-validation. The experimental results show that the simplest architecture, consisting of a single hidden layer with 64 neurons, a learning rate of 0.001, and an n-gram configuration of (1,1), achieved the best performance, with macro accuracy of 91.43%, F1-score of 89.59%, and Hamming loss of 0.0857.
