Abstract

Aswaya merupakan Learning Management System (LMS) yang dikembangkan Universitas Pradita untuk mendukung proses pembelajaran mahasiswa, mulai dari penyampaian materi, pengumpulan tugas, hingga interaksi dengan dosen dan mahasiswa. Namun, hasil observasi dan wawancara menunjukkan bahwa pemanfaatan Aswaya belum sepenuhnya efektif dan masih belum memenuhi harapan manajemen. Kendala utama dialami pengguna terkait desain antarmuka (UI) dan pengalaman pengguna (UX) yang dinilai kurang optimal, sehingga menurunkan kenyamanan serta motivasi dalam menggunakan platform tersebut. Untuk mengatasi permasalahan ini, digunakan metodologi Design Thinking yang berfokus pada kebutuhan pengguna melalui pendekatan kreatif dan iteratif. Proses evaluasi dilakukan dengan pengujian prototipe menggunakan System Usability Scale (SUS) dan Post-Study System Usability Questionnaire (PSSUQ). Hasilnya, skor SUS pada iterasi pertama mencapai 75 dan nilai PSSUQ pada iterasi kedua sebesar 6. Temuan ini menunjukkan bahwa Aswaya telah memenuhi standar kegunaan yang baik, meskipun peningkatan pada kualitas informasi masih diperlukan.

Abstract

Social networking is becoming more and more important. Social media's purpose has evolved from its first appearance as a place just for self-actualization to include online buying and selling, self-actualization, and other functions. Tik tok is one of the social media platforms that is currently in high demand; opinions about its rise are mixed and include both positive and negative aspects. The goal of this study is to closely examine and comprehend how people react to the phenomena of Tiktok's development by keeping an eye on user-generated material in tweets and the evolution of sentiment over time. This experimental study suggests using the Naïve Bayes Algorithm as a sentiment analysis method to examine how Twitter users are responding to the TikTok craze. In-depth insights into the dynamics of Twitter users' reactions to the TikTok trend are sought by this research, which combines sentiment analysis technology with Confusion Matrix performance evaluation. According to the sentiment analysis results, the majority of user comments are neutral (57.03%), followed by critical (33.20%) and affirmative (9.77%) remarks. This illustrates the nuanced reactions that people have had to the TikTok movement, in which the majority of users share their ideas in an unbiased manner. The significance of this research lies in its ability to provide an answer.

Abstract

Perkembangan pesat kecerdasan buatan dan pembelajaran mendalam telah mendorong eksplorasi berbagai arsitektur jaringan saraf untuk pengolahan data non-visual, seperti data numerik, sekuensial, dan tekstual. Dua arsitektur yang paling banyak digunakan dan berkembang adalah Convolutional Neural Network (CNN) dan Transformer. Meskipun CNN telah lama digunakan secara luas karena efisiensinya dalam mengekstraksi fitur lokal, arsitektur Transformer dengan mekanisme self-attention menawarkan kemampuan unggul dalam menangkap hubungan global dan dependensi kompleks antar elemen data. Penelitian ini bertujuan untuk membandingkan kinerja dan efisiensi arsitektur CNN dan Transformer dalam pengolahan data non-visual melalui pendekatan eksperimental kuantitatif. Dataset non-visual digunakan dan melalui tahapan pra-pemrosesan sebelum dilakukan pelatihan dan pengujian model. Evaluasi performa dilakukan menggunakan metrik akurasi, precision, recall, dan F1-score, serta analisis efisiensi komputasi berdasarkan waktu pelatihan dan kompleksitas model. Hasil penelitian menunjukkan bahwa Transformer secara konsisten mencapai performa yang lebih tinggi dibandingkan CNN pada seluruh metrik evaluasi, khususnya dalam menangani pola kompleks dan hubungan jangka panjang pada data non-visual. Namun, CNN menunjukkan keunggulan dalam efisiensi komputasi dan kestabilan pelatihan dengan kebutuhan sumber daya yang lebih rendah. Temuan ini mengindikasikan bahwa tidak terdapat satu arsitektur yang sepenuhnya unggul dalam semua aspek, melainkan pemilihan model harus disesuaikan dengan karakteristik data dan kebutuhan aplikasi. Selain itu, penelitian ini menyoroti potensi pendekatan hibrida yang mengombinasikan CNN dan Transformer untuk meningkatkan performa dan generalisasi model. Penelitian ini diharapkan dapat menjadi referensi empiris bagi pengembangan sistem cerdas berbasis pembelajaran mendalam dalam pengolahan data non-visual.

Abstract

Text classification of academic documents, particularly thesis titles, poses challenges due to high dimensionality, sparsity, and topic heterogeneity. Conventional feature selection techniques, such as the standard Chi-Square, often fall short in capturing discriminative features effectively. This research aims to enhance classification accuracy by proposing a Modified Chi-Square feature selection method that integrates term frequency and class distribution information. The selected features are then classified using ensemble decision tree algorithms, including Random Forest, Gradient Boosting, and XGBoost. Experiments were conducted on a labeled dataset of thesis titles using TF-IDF for vector representation. Evaluation metrics such as accuracy, precision, recall, F1-score, and AUC were used to assess model performance. The results showed that the combination of Modified Chi-Square and XGBoost outperformed other models, achieving the highest accuracy of 93.8% and an AUC of 0.94. These findings demonstrate that the integration of advanced feature selection and ensemble learning techniques can significantly improve academic text classification performance, providing valuable implications for the development of intelligent digital repositories and recommendation systems.

Abstract

Using immersive technology in regional planning is now essential to provide an accurate picture of how areas will develop in the future. This study aims to design and develop a Virtual Reality (VR) Tour application that visualizes the integrated coastal tourism plan in Tangerang Regency. The coastal area of Tangerang has a lot of potential but needs more interactive social media communication to involve stakeholders and the community in planning. The development method used is the Multimedia Development Life Cycle (MDLC), which consists of six stages: concept, design, collecting materials, assembly, testing, and distribution. The development was done using Roblox Studio because of its strengths in rendering multi-user environments and the ease of access across different devices. The result of this research is a VR application that allows users to explore a digital prototype of the tourism area, including infrastructure facilities and mangrove conservation areas, in an immersive way. Testing the app showed that using VR devices gives a more detailed spatial experience compared to traditional models or 2D maps. This study concludes that using Roblox Studio with the MDLC method is effective in speeding up the process of creating VR prototypes for coastal tourism planning that is both communicative and educational.

Abstract

One of the efforts to break down traffic jams is to establish special lanes that can be passed by two, four, or more wheeled vehicles. By being able to recognize the type of vehicle can reduce congestion. Citran based vehicle classification helps in providing information about the vehicle type. This study aims to classify the type of vehicle using a backpropagation neural network algorithm. The vehicle image can be recognized based on its shape, then the backpropagation neural network algorithm will be supported by metric and eccentricity parameters to perform feature extraction. Then from the results of feature extraction with metric parameters and eccentricity, the object will be classified using a backpropagation neural network algorithm. The test results show an accuracy of 87.5%. This shows the algorithm can perform classification well.
