Abstract

AbstrakPenentuan peminatan akademik mahasiswa merupakan tahapan penting dalam pendidikan tinggi karena berpengaruh terhadap keberhasilan studi dan pengembangan kompetensi. Namun, proses penentuan peminatan sering kali masih dilakukan secara subjektif dan belum sepenuhnya berbasis data akademik. Penelitian ini bertujuan untuk membandingkan performa algoritma Support Vector Machine (SVM) dan K-Nearest Neighbors (KNN) dalam memprediksi peminatan akademik mahasiswa Program Studi Manajemen Universitas Muhammadiyah Makassar. Data penelitian bersumber dari nilai mata kuliah inti mahasiswa angkatan 2018 hingga 2021 yang telah melalui tahapan prapemrosesan dan pelabelan ke dalam tiga konsentrasi, yaitu Sumber Daya Manusia, Pemasaran, dan Keuangan. Metode penelitian dilakukan dengan membangun model klasifikasi menggunakan algoritma SVM dan KNN, kemudian dievaluasi menggunakan metrik akurasi, precision, recall, dan f1-score dengan variasi parameter serta pembagian data latih dan data uji. Hasil pengujian menunjukkan bahwa algoritma SVM dengan kernel Radial Basis Function (RBF) dan test size 0,1 menghasilkan performa terbaik dengan nilai akurasi sebesar 70,55 persen. Sementara itu, algoritma KNN dengan nilai k sebesar lima, metrik jarak Euclidean, dan test size 0,1 memperoleh akurasi sebesar 57,53 persen. Temuan ini menunjukkan bahwa SVM memiliki kemampuan klasifikasi yang lebih baik dan stabil dibandingkan KNN, sehingga lebih layak diterapkan sebagai model pendukung sistem prediksi peminatan akademik mahasiswa berbasis pembelajaran mesin.Kata kunci: Support Vector Machine, K-Nearest Neighbors, Machine Learning.Abstract Determining academic specialization for university students is a crucial stage in higher education because it directly influences study success and competency development. However, the process is often conducted subjectively and is not fully based on academic data. This study aims to compare the performance of Support Vector Machine and K-Nearest Neighbors algorithms in predicting academic specialization of Management students at Universitas Muhammadiyah Makassar. The dataset consists of core course grades from cohorts 2018 to 2021 that were preprocessed and labeled into three concentrations: Human Resource Management, Marketing, and Finance. The research method involved building classification models using SVM and KNN, which were evaluated using accuracy, precision, recall, and F1-score with various parameter settings and train–test splits. The results show that SVM with a Radial Basis Function kernel and a test size of 0.1 achieved the best performance with an accuracy of 70.55 percent. Meanwhile, KNN with k equal to five, Euclidean distance, and a test size of 0.1 obtained an accuracy of 57.53 percent. These findings indicate that SVM provides more stable and accurate classification than KNN for academic specialization prediction. Therefore, SVM is considered more suitable as a machine learning based decision support model for academic specialization purposes effectively.Keyword: Support Vector Machine, K-Nearest Neighbors, Machine Learning.

Abstract

Selada (Lactuca sativa L.) merupakan komoditas hortikultura bernilai ekonomi tinggi, namun produktivitasnya sering terhambat oleh serangan penyakit. Identifikasi manual oleh petani seringkali tidak akurat karena kemiripan gejala visual antar penyakit. Penelitian ini bertujuan untuk membangun sistem identifikasi penyakit otomatis menggunakan Support Vector Machine (SVM) berbasis ekstraksi fitur visual. Penelitian berfokus pada klasifikasi empat kondisi daun selada: Sehat, Bercak Daun Cercospora, Tipburn, dan Etiolasi. Metodologi yang digunakan meliputi ekstraksi fitur warna dari ruang warna HSV dan fitur tekstur menggunakan Gray-Level Co-occurrence Matrix (GLCM). Efektivitas augmentasi data dan optimasi hyperparameter menggunakan Particle Swarm Optimization (PSO) juga dievaluasi melalui tiga skenario perbandingan. Hasil penelitian menunjukkan bahwa augmentasi data secara signifikan meningkatkan akurasi model dari baseline 69,57% menjadi 92,28%. Optimasi lebih lanjut dengan PSO berhasil meningkatkan performa hingga mencapai akurasi final sebesar 93,63%. Model terbaik menunjukkan F1-Score yang seimbang di atas 0,91 untuk semua kelas, membuktikan bahwa kombinasi metode ekstraksi fitur HSV dan GLCM, augmentasi data, dan optimasi SVM menggunakan PSO merupakan pendekatan yang andal dan efektif untuk identifikasi penyakit daun selada, serta menawarkan alat bantu yang prospektif untuk pertanian presisi

Abstract

Manual identification ofboycott products remains a challenge for the public due to limited access to information and the complexity of brand affiliations. This study aims to develop a real-time, website-based boycott product detection system using the You Only Look Once version 10 (YOLOv10) algorithm. The dataset consists of images of food and beverage product packaging collected from various online sources, annotated using the bounding box method, and classified into five categories. The model was trained and tested using separate test data, while performance evaluation was conducted using a confusion matrix with precision, recall, and f1-score metrics. In addition, functional testing of the system was performed using the Black Box Testing method. The result indicate that the YOLOv10 model is capable of detecting boycott product with good performance and can be effectively integrated into a real-time web-based system. The proposed system is expected to assist users in identifying boycott products more quickly and accurately.

Abstract

Face recognition based on image data has been widely applied in automated attendance systems; however, it still faces challenges related to accuracy and efficiency under varying lighting conditions and facial pose variations. This study aims to compare the performance of Convolutional Neural Network (CNN) and You Only Look Once (YOLO) methods for face detection and recognition in a deep learning–based attendance system. The dataset consists of facial images collected from students in a limited campus environment with several variations in viewpoint and illumination. The research stages include image preprocessing, training of CNN and YOLO models, and performance evaluation using accuracy, precision, recall, and computation time metrics. The experimental results indicate that YOLO outperforms CNN in terms of detection speed and performance stability, while CNN demonstrates competitive classification performance on limited datasets. This study provides empirical insights into the characteristics of both methods in attendance system scenarios and can serve as a reference for selecting appropriate models for real-world implementation. The main limitations of this study are the dataset size and the restricted data acquisition scope.

Abstract

Emotion recognition plays a critical role in intelligent e-learning systems by enabling adaptive feedback and timely pedagogical interventions based on students’ affective states. However, most existing approaches rely heavily on visual facial cues, which are highly vulnerable to real-world conditions such as low-resolution video, partial facial occlusion, poor lighting, and unstable network connections commonly encountered in online learning environments. These limitations significantly degrade the performance of unimodal deep learning models. To address this challenge, this study proposes a multimodal deep learning framework for student emotion recognition that is robust to low-quality and occluded video input. The proposed model integrates visual and audio modalities through a hybrid architecture, combining a lightweight CNN-based visual feature extractor with a BiLSTM-based speech emotion model. An attention-based fusion mechanism is employed to adaptively weight cross-modal features, allowing the system to compensate for degraded or missing visual information using complementary acoustic cues. Experimental evaluations are conducted using publicly available datasets representative of realistic online learning scenarios, including DAiSEE and RAVDESS, with additional augmentation to simulate varying levels of occlusion and video degradation. The results demonstrate that the multimodal approach consistently outperforms unimodal baselines, particularly under high occlusion conditions, while maintaining computational efficiency suitable for near real-time deployment. These findings confirm that multimodal fusion with attention mechanisms provides a more resilient and practical solution for emotion-aware e-learning systems operating under non-ideal input conditions

Abstract

This study develops a transparent MCDA–AHP–GIS framework to screen Multi-Utility Tunnel (MUT) corridor suitability in Panakkukang Sub-district, Makassar City, using 2024 baseline datasets and five criteria: utility/network density (C1), road functional class and corridor capacity (C2), flood susceptibility (C3), activity intensity (C4; proxied by kelurahan-level population density), and spatial planning compatibility with RTRW/RDTR (C5). All layers were standardized and reclassified (1–3 or 1–5) and integrated using Weighted Linear Combination (WLC) with AHP-derived weights (CR = 0.028), where C1 (0.26) and C5 (0.24) were highest, followed by C2 (0.19), C4 (0.16), and C3 (0.15). The 2,918.3-ha study area was classified into Very Unsuitable (88.2 ha; 3.0%), Unsuitable (405.8 ha; 13.9%), Moderately Suitable (764.9 ha; 26.2%), Suitable (935.8 ha; 32.1%), and Highly Suitable (723.6 ha; 24.8%). A corridor-focused overlay shows that 436.9 ha fall within the Suitable–Highly Suitable mask, of which 127.3 ha (29.1%) intersect high flood-hazard zones, indicating that some priority segments require attention during detailed planning. Uncertainty mainly arises from buffer distances and reclassification thresholds and from non-differentiating attributes in some utility layers; however, a ±10% weight sensitivity test yields only minor shifts in class areas and preserves the main priority-corridor pattern.

Abstract

Penelitian ini bertujuan mengembangkan sistem segmentasi citra untuk menghitung persentase area kerusakan daun bawang menggunakan model hybrid transformer berbasis SegFormer-TransUNet. Permasalahan utama yang diangkat adalah keterbatasan penilaian visual manual yang cenderung subjektif, lambat, dan sulit diterapkan secara konsisten pada skala lahan yang luas. Data penelitian berupa citra daun bawang dan mask anotasi yang memisahkan area daun sehat, daun rusak, dan background. Tahapan penelitian meliputi akuisisi citra, preprocessing, pembentukan label mask, pelatihan tiga skenario model, evaluasi kuantitatif, serta perhitungan persentase kerusakan berbasis rasio piksel. Model hybrid dirancang dengan memanfaatkan SegFormer sebagai encoder untuk menangkap konteks global dan TransUNet sebagai decoder untuk merekonstruksi detail spasial. Hasil evaluasi menunjukkan bahwa model hybrid memperoleh accuracy 0,9590, mIoU 0,8333, dan Dice coefficient 0,8686. Nilai tersebut lebih tinggi dibandingkan SegFormer (accuracy 0,9543; mIoU 0,7671; Dice 0,8057) dan TransUNet (accuracy 0,9583; mIoU 0,8145; Dice 0,8509) pada metrik utama segmentasi. Temuan ini menunjukkan bahwa integrasi fitur global dan detail lokal mampu meningkatkan kualitas segmentasi serta menghasilkan dasar kuantitatif untuk estimasi tingkat kerusakan daun bawang.

Abstract

Sustainable planning of green open spaces (GOS) requires decision-making models that combine expert evaluation with public input. This study proposes a novel hybrid framework that integrates multi-criteria group decision making (MCGDM) with public sentiment analysis to support community-based and data-driven urban planning. The workflow consists of evaluating 25 community-proposed GOS locations using stepwise weight assessment ratio analysis (SWARA) for criteria weighting and MABAC-BORDA for multi-criteria ranking, resulting in 11 feasible alternatives. To incorporate community perspectives, a term frequency-inverse document frequency-support vector machine (TF-IDF–SVM) classifier was applied to 1500 public comments, where SVM achieved the highest accuracy (0.80–0.96). The integrated approach improves ranking stability, reduces decision ambiguity, and strengthens alignment between expert judgment and community sentiment. This study contributes a transparent, participatory decision-support model that unifies MCGDM and sentiment analysis to enhance the effectiveness of sustainable GOS planning.
