Abstract

Fingerprint recognition technology is integral to biometric security systems, providing secure and reliable identification through unique human fingerprint patterns. However, challenges such as low contrast, high intra-class variability, and partial fingerprints often compromise the efficiency and accuracy of traditional recognition systems. This research addresses these challenges by employing advanced deep learning techniques, specifically Convolutional Neural Networks (CNNs), to enhance fingerprint recognition performance. We propose a methodological approach that leverages state-of-the-art CNN architectures tailored to capture intricate fingerprint details. The study utilizes the Sokoto Coventry Fingerprint Dataset (SOCOFing), which includes diverse fingerprint types and synthetic alterations to evaluate model performance under realistic conditions. Through a comparative analysis of various CNN configurations, we assessed the models based on efficiency and accuracy, using metrics such as accuracy, precision, recall, and F1-score. Our experimental results demonstrate significant improvements in fingerprint recognition capabilities. The optimized CNN model achieved an accuracy of 98.61%, a precision of 97.12%, a recall of 97.46%, and an F1-score of 97.29%. These results validate the effectiveness of CNNs in handling complex biometric data and underscore their potential to enhance the reliability and security of fingerprint recognition systems. The study concludes that deep learning, through the use of CNNs, offers a powerful solution to the limitations of traditional fingerprint recognition techniques. This will pave the way for more sophisticated and accurate biometric security systems in practical applications. The research findings contribute to ongoing advancements in neural network architectures, enhancing their applicability in increasingly automated and data-driven security environments.

Abstract

This study aims to analyze the impact of strategic product placement and promotion strategies using the Customer's Purchase Behavior Dataset. The study utilized a controlled experimental design, wherein trial stores were matched with control stores based on pre-trial performance metrics, including total sales and customer demographics. A detailed exploratory data analysis (EDA) was conducted to segment customers based on life-stage and purchasing behaviour. Additionally, a t-Test was performed to determine whether price sensitivity and purchasing patterns differed significantly between mainstream, budget, and premium customer segments. The results indicate that trial stores implementing strategic initiatives experienced a measurable uplift in sales compared to their control counterparts. Young and mid-age singles and couples in the mainstream category were found to be more willing to pay a premium for chips, whereas families tended to purchase in bulk. The t-test confirmed statistically significant differences in purchasing behaviour across customer segments. The findings suggest that a data-driven, segment-specific marketing approach can optimise retail performance by aligning promotions and pricing with the behavioural tendencies of different consumer groups. This study demonstrates that well-targeted strategic retail initiatives can significantly improve sales performance. The insights derived from this research provide retailers with actionable strategies for tailoring product placement and promotions to maximise customer engagement. Future work should incorporate machine learning techniques to refine predictive models for real-time decision-making in retail marketing.

Abstract

This research aims to optimize sentiment analysis by leveraging the strengths of multiple Support Vector Machine (SVM) kernels—Linear, RBF, Polynomial, and Sigmoid—through an ensemble learning approach. This study introduces a novel model called SVM Porlis, which integrates these kernels using both hard and soft voting strategies to improve the classification performance on imbalanced datasets. Sentiment classification in this study involves two classes: positive and negative. Tweets related to the controversy over the naturalization of Indonesian national football players were collected using the official X/Twitter API, resulting in a dataset of 2,248 entries. The dataset was notably imbalanced, with significantly more negative samples than positive samples. Data preprocessing included cleaning, labeling, tokenization, stopword removal, stemming, and feature extraction using TF-IDF. To address the class imbalance, the SMOTE technique was applied to synthetically augment the minority class. Each SVM kernel was trained and evaluated individually before being combined into an SVM Porlis model. Evaluation metrics included accuracy, precision, recall, F1-score, and confusion matrix analysis. The results demonstrate that SVM Porlis with soft voting achieved the highest performance, with 98% accuracy, precision, recall, and F1-score, surpassing the performance of individual kernels and other ensemble approaches such as SVM + Chi-Square and SVM + PSO. These findings highlight the effectiveness of combining multiple kernels to capture both linear and non-linear patterns, offering a robust and adaptive solution for sentiment analysis in real-world, imbalanced data scenarios.

Abstract

This research proposes a hybrid rating prediction model that integrates Neural Collaborative Filtering (NCF), Long Short-Term Memory (LSTM), and semantic analysis through Natural Language Processing (NLP) to enhance recommendation accuracy. The main objective is to improve alignment between system predictions and actual user preferences by leveraging multi-source information from the Amazon Movies and TV dataset, which includes explicit user–item ratings and textual reviews. The core idea is to combine three complementary processing paths—(1) user–item interaction modeling via NCF, (2) temporal dynamics capture through LSTM, and (3) semantic understanding of reviews using NLP—into a unified deep learning-based adaptive architecture. Experimental evaluation demonstrates that this multi-input approach outperforms the baseline collaborative filtering model, with the Mean Absolute Error (MAE) reduced from 1.3201 to 1.2817 (a 2.91% improvement) and the Mean Squared Error (MSE) reduced from 2.2315 to 2.1894 (a 1.89% improvement). Training metrics visualization further shows a stable convergence pattern, with the MAE gap between training and validation consistently below 0.03, indicating minimal overfitting. The findings confirm that integrating cross-dimensional signals significantly enhances predictive performance and can contribute to increased user satisfaction and engagement in recommendation platforms. The novelty of this work lies in the simultaneous integration of interaction, temporal, and semantic dimensions into a single adaptive recommendation framework, a configuration not jointly explored in prior studies. Moreover, the flexible architecture enables adaptation to other domains such as e-commerce, music, or online learning, broadening its practical applicability.

Abstract

 Abstract: Student attendance is one of the activities carried out in the lecture process. Attendance is also an element of a student's final grade for each course offered in accordance with a university's academic guidelines. Attendance at STMIK Amik Riau is done manually, where students are called one by one and then the lecturer changes the attendance data in SIMDOS. This method is of course very inefficient, and takes a long time. Apart from that, this manual process is prone to fraud where students can make absences. Therefore, this research proposes a QR-Code based student attendance mobile application prototype at STMIK Amik Riau using the User Centered Design (UCD) method. The results of the research are in the form of a prototype or user interface design for the student attendance mobile application. It is hoped that this prototype can help programmers to build QR-Code based student attendance mobile applications. Keywords: Presence, QR-Code, User Interface, User Centered Design =Abstrak: Kehadiran atau presensi mahasiswa merupakan salah satu kegiatan yang dilakukan dalam proses perkuliahan. Presensi juga merupakan salah satu elemen nilai akhir mahasiswa setiap mata kuliah yang ditawarkan sesuai dengan panduan akademik suatu perguruan tinggi. Presensi di STMIK Amik Riau dilakukan secara manual, dimana mahasiswa dipanggil satu per satu lalu dosen merubah data presensi yang ada pada SIMDOS. Cara ini tentunya sangat tidak efisien, dan membutuhkan waktu yang lama. Selain itu proses manual ini rentan terjadi kecurangan dimana mahasiswa dapat melakukan titip absen. Oleh karena itu penelitian ini mengusulkan prototype aplikasi mobile presensi mahasiswa berbasis QR-Code di STMIK Amik Riau menggunakan metode User Centered Design (UCD). Hasil dari penelitian berupa prototype atau rancangan user interface aplikasi mobile presensi mahasiswa. Diharapkan prototype ini dapat membantu programmer untuk membangun aplikasi mobile presensi mahasiswa berbasis QR-Code. Kata kunci: Presensi, QR-Code, User Interface, User Centered Design

Abstract

The Free Nutritious Meal Program (MBG) is a public policy that requires evaluation based on public opinion. This study developed a Long Short-Term Memory (LSTM) model to classify public sentiment from 13,923 X reviews, collected using the tweet-harvest library. The data was processed with Word2Vec weighting and Lexicon-Based labeling, resulting in 73.4% positive sentiment and 26.6% negative sentiment. The model was tested with train-test split ratios of 60:40, 70:30, 80:20, and 90:10, with the best performance at a ratio of 80:20 (91.71% accuracy, 89% precision, 90% recall, 89% F1-score). The model architecture includes Embedding, LSTM (128 units), Dropout (70%), and Dense layers, optimized with categorical_crossentropy and Adam. The confusion matrix evaluation shows the effectiveness of the model, despite weak negative classes due to data imbalance. The results provide insights for improving MBG implementation, with LSTM excelling at capturing text patterns compared to SVM and BERT.
