Abstract

A marketplace is a place in cyberspace where there are commercial activities between buyers and sellers. Products offered from the marketplace have reviews to review. Shopee is the most visited marketplace by people and offers various products. Product reviews can provide benefits for other consumers in assessing the products offered. By utilizing NLP technology in particular, this study can classify positive sentiment and negative sentiment in product review data. The IndoBERT model is a model that can be used in NLP technology by utilizing the relationship between each input and output element as well as the weights to be calculated simultaneously. By utilizing this technology, sentiment analysis on Shopee product reviews provides maximum accuracy until 93% with different training conditions. This provide that IndoBERT model can show that the performance of the indoBERT model in this research is very good.

Abstract

Nowadays, humans cannot be separated from information technology; this significantly impacts various fields, especially educational administration. Academic services that were initially manual have now transformed into digital, where academic data, both information and other administration, can now be handled by information systems. This study aimed to determine the effectiveness of implementing the integrated academic information system (SIAT) that has been running in Islamic universities. Data collection was carried out using a descriptive qualitative method concerning the field research approach combined with data triangulation; data collection was obtained by distributing questionnaires, qualitative interviews, and observations. The findings were that SIAT could increase the effectiveness and efficiency of academic services at the Faculty, ease of accessing information, especially in KRS filling activities, KHS checking, lecture monitoring, lecturer grade input, and distribution of lecture schedules can be done in one system. The obstacles felt were few, especially if the system was undergoing maintenance, data loading was hampered, and some students did not understand how to operate the information system. The solution that can be done is to hold periodic socialization regarding the implementation of SIAT and to update the system so that it remains optimal in its operation.

Abstract

Keretakan permukaan gedung merupakan salah satu permasalahan yang sering terjadi pada bangunan, yang disebabkan oleh faktor-faktor seperti bencana alam, perubahan temperatur, kelembaban tinggi, dan penggunaan bahan bangunan berkualitas rendah. Permasalahan ini dapat mengancam keselamatan dan kenyamanan pengguna bangunan jika tidak segera ditangani. Metode konvensional dalam mendeteksi keretakan pada bangunan sering kali melibatkan inspeksi manual yang memakan waktu dan berisiko tinggi. Penelitian ini bertujuan untuk mengembangkan sistem deteksi keretakan permukaan gedung menggunakan algoritma YOLO (You Only Look Once) berbasis web. Sistem ini dirancang untuk meningkatkan efisiensi dan akurasi dalam mendeteksi keretakan dengan memanfaatkan teknologi pemrosesan citra dan pembelajaran mendalam (deep learning). Algoritma YOLO dipilih karena kemampuannya dalam melakukan deteksi objek secara dengan tingkat akurasi yang tinggi. Hasil evaluasi menunjukkan bahwa sistem deteksi keretakan permukaan gedung menggunakan algoritma YOLOv8 berbasis web berhasil mencapai tingkat akurasi sebesar 54,8%, dengan nilai precision sebesar 62,9%, recall sebesar 81,1%, F1-score sebesar 70,1%, dan nilai mAP sebesar 75,1%. Dengan demikian, sistem ini diharapkan dapat menjadi solusi yang efektif dan efisien dalam memantau kondisi bangunan, mengurangi risiko kecelakaan kerja, dan meningkatkan keselamatan serta kenyamanan pengguna gedung.

Abstract

The research aims to raise awareness about protected marine species in Papua through a chatbot providing accessible information. This strengthens public and student understanding of marine conservation. Methods include problem analysis, literature study, data collection, and system analysis and design using PyMuPDF and a Large Language Model (LLM). Data from scientific journals, books, e-books, and websites is processed through chunking and embedding to create vector representations. The FITZ library stores these vectors, enabling the chatbot to find similarities and provide relevant answers. Results show the chatbot accurately delivers information on Papua's protected marine animals. Testing with BERTScore indicated a high semantic correlation between chatbot responses and reference data. User satisfaction surveys reveal positive contributions to understanding marine conservation. The chatbot is relevant and satisfying, though performance and functionality could be improved with advanced technology. Further research should enhance data quality and answer consistency to better meet user needs.

Abstract

Kebutuhan akan perangkat keras seperti mouse untuk bermain gim yang mendukung performa meningkat seiring dengan pertumbuhan industri gim dan teknologi digital. Fitur seperti DPI tinggi, tombol makro, sensor presisi, dan desain ergonomis menjadi daya tarik utama bagi pengguna. Namun, banyaknya variasi produk membuat konsumen kesulitan memilih mouse yang sesuai dengan preferensi mereka. Penelitian ini bertujuan untuk membangun sistem rekomendasi mouse gaming berbasis pembelajaran mesin dengan membandingkan dua algoritma, yaitu K-Nearest Neighbor (K-NN) dan K-Means. Metode penelitian meliputi pengumpulan data dari Kaggle, preprocessing data (pembersihan, normalisasi), reduksi dimensi dengan PCA, pengelompokan menggunakan K-Means, serta klasifikasi menggunakan K-NN dengan penerapan SMOTE untuk mengatasi ketidakseimbangan kelas. K-NN, sebagai algoritma supervised learning, memanfaatkan kedekatan antar data untuk menentukan label, sedangkan K-Means merupakan algoritma unsupervised yang mengelompokkan data berdasarkan kemiripan fitur. Evaluasi dilakukan menggunakan metrik akurasi, presisi, recall, dan F1-score. Hasil menunjukkan bahwa K-Means efektif dalam segmentasi produk, sementara K-NN memberikan akurasi tinggi dalam klasifikasi. Kombinasi keduanya menghasilkan sistem rekomendasi yang lebih akurat dan relevan bagi pengguna.

Dataset terdiri dari 1950 gambar wajah yang telah diproses melalui tahapan preprocessing serta augmentation. Evaluasi dilakukan menggunakan metrik akurasi, precision, recall, F1-score, confusion matrix, serta waktu komputasi. Hasil pengujian menunjukkan bahwa EfficientNetB7 memberikan performa terbaik dengan mencapai akurasi tertinggi sebesar 93%, diikuti oleh ResNet50 sebesar 91%, dan MobileNetV3 sebesar 87%. Dengan demikian, arsitektur EfficientNetB7 menunjukkan kemampuan ekstraksi fitur visual yang lebih unggul dan berpotensi diterapkan pada sistem identifikasi kulit wajah berbasis sistem cerdas.   Abstract Automatic classification of facial skin types has become an important requirement in supporting the selection of appropriate and objective skincare treatments. A deep learning approach based on image analysis offers a more accurate solution compared to conventional methods. This study aims to analyze and compare the performance of three pre-trained Convolutional Neural Network (CNN) architectures, namely EfficientNetB7, ResNet50, and MobileNetV3, for the classification of five categories. The dataset consists of 1,950 facial images that have been processed through preprocessing and augmentation stages. The evaluation was conducted using accuracy, precision, recall, F1-score, confusion matrix, and computational time metrics. The experimental results show that EfficientNetB7 achieves the best performance with the highest accuracy of 93%, followed by ResNet50 at 91%, and MobileNetV3 at 87%. Therefore, the EfficientNetB7 architecture demonstrates superior visual feature extraction capability and has strong potential to be implemented in intelligent facial skin identification systems.
