Abstract

This research delves into the critical analysis of vulnerabilities arising from the advent of quantum computing in traditional cryptographic systems. Employing a newly developed mathematical formulation model, the study meticulously evaluates the susceptibility of classical encryption methods, exemplified by XYZ Bank's RSA and ECC algorithms, to quantum algorithms such as Shor's and Grover's. The assessment reveals pronounced vulnerabilities, particularly highlighting the high susceptibility of RSA encryption to quantum attacks, emphasizing the urgent need to fortify existing cryptographic systems. The research rigorously evaluates potential countermeasures, with Post-Quantum Cryptography (PQC) emerging as a promising solution, showcasing superior effectiveness in mitigating vulnerabilities posed by quantum algorithms. The strategic imperative for organizations to transition towards PQC or other post-quantum cryptographic standards is evident, signaling a paradigm shift towards resilient encryption methods resilient to the disruptive capabilities of quantum computing. The research underscores the significance of collaboration among industry stakeholders, continuous research endeavors, and proactive measures in adopting quantum-resistant cryptographic standards to fortify data security strategies against potential quantum threats in an ever-evolving technological landscape.

Abstract

One of the biggest obstacles to creating precise machine learning models is choosing representative and pertinent characteristics from big, unbalanced datasets. While too many features raise the risk of overfitting and computational expense, class imbalance frequently results in decreased accuracy and bias. The Simulated Annealing technique is used in this study to tackle a Quadratic Unconstrained Binary Optimization (QUBO) problem that is formulated as a quantum-assisted feature selection method to handle these problems. The technique seeks to reduce inter-feature redundancy and the number of selected features. There are 102,487 samples in the majority class and 11,239 in the minority class, totaling 28 characteristics in the experimental dataset. Nine ideal features were found during the feature selection method (12, 14, 15, 22, 23, 24, 25, 27, and 28). Ten-fold cross-validation was used to assess a Random Forest Classifier that was trained using an 80:20 split. With precision, recall, f1-score, and accuracy all hitting 1.00, the suggested QUBO+SMOTE method demonstrated exceptional performance. Comparatively, QUBO without SMOTE performed worse with accuracy 0.95 and minority-class f1-score of only 0.71, whereas a traditional Recursive Feature Elimination (RFE) approach obtained accuracy 0.97 with minority-class f1-score of 0.94. These findings indicate that QUBO can reduce dimensionality and address class imbalance which requires its integration with SMOTE. This study demonstrates how quantum computing can enhance the effectiveness and efficiency of machine learning, especially for large-scale imbalanced datasets

Abstract

Kecelakaan lalu lintas akibat kantuk saat mengemudi merupakan salah satu penyebab utama kematian di jalan raya dan menjadi isu keselamatan yang krusial. Studi menunjukkan bahwa 20–30% kecelakaan disebabkan oleh pengemudi yang mengantuk, sehingga diperlukan sistem peringatan dini yang mampu mendeteksi kondisi ini secara akurat dan real-time. Penelitian ini bertujuan untuk mengembangkan model deteksi kantuk berbasis visi komputer menggunakan algoritma YOLOv11n, yang dikenal sebagai varian ringan dan cepat dari keluarga YOLO. Model dilatih menggunakan dataset citra wajah yang telah diproses dan diaugmentasi melalui platform Roboflow, dengan tujuan untuk mendeteksi tanda-tanda kantuk secara visual. Hasil evaluasi model menunjukkan performa yang sangat baik, dengan nilai mAP50 sebesar 0,9710 dan mAP50-95 sebesar 0,6796. Selain itu, precision mencapai 0,9382 dan recall sebesar 0,9280, yang mengindikasikan kemampuan deteksi yang tinggi serta tingkat kesalahan yang rendah. Temuan ini membuktikan bahwa YOLOv11n dapat diimplementasikan secara efektif dalam sistem peringatan dini untuk meningkatkan keselamatan pengemudi, bahkan pada perangkat dengan sumber daya terbatas. Penelitian ini tidak hanya menjawab tantangan efisiensi dan akurasi deteksi kantuk, tetapi juga memberikan kontribusi nyata bagi pengembangan sistem keselamatan kendaraan berbasis kecerdasan buatan. Ke depan, pengembangan sistem deteksi multimodal yang menggabungkan citra wajah dengan data fisiologis seperti EOG dan detak kepala disarankan untuk meningkatkan keandalan sistem dalam kondisi nyata.

Abstract

Jeruk merupakan salah satu buah tropis yang banyak dikonsumsi masyarakat karena kandungan nutrisinya yang tinggi, khususnya vitamin C. Namun, produksi jeruk kerap mengalami penurunan akibat serangan penyakit, terutama pada bagian daun. Identifikasi penyakit secara manual dinilai kurang efisien dan rawan kesalahan, sehingga diperlukan sistem otomatis berbasis machine learning untuk membantu proses deteksi secara cepat dan akurat. Penelitian ini bertujuan untuk membandingkan tiga algoritma klasifikasi K-Nearest Neighbor (KNN), Support Vector Machine (SVM), dan Neural Network (NN) dalam mengidentifikasi penyakit daun jeruk berdasarkan fitur tekstur. Dataset yang digunakan terdiri dari lima kategori: Black Spot, Canker, Greening, Melanose, dan Healthy, dengan total 609 citra daun yang dibagi secara proporsional untuk pelatihan dan pengujian. Hasil evaluasi menunjukkan bahwa model Neural Network memberikan performa terbaik dengan akurasi 87,5%, diikuti oleh SVM sebesar 82,4%, dan KNN sebesar 77,5%. Penelitian ini menunjukkan bahwa pendekatan machine learning, khususnya Neural Network, efektif dalam klasifikasi penyakit daun jeruk dan berpotensi untuk diimplementasikan lebih lanjut dalam bentuk aplikasi praktis bagi petani.

Abstract

Anemia is a condition where the number of red blood cells or hemoglobin levels is below normal, reducing the blood’s ability to carry oxygen, which can lead to symptoms such as fatigue, weakness, and shortness of breath.This study aims to utilize a quantum computing approach to improve the performance of the K-Medoids method by calculating the Chebyshev Distance to predict anemia. The method used is the K-Medoids clustering method with the calculation of the Chebyshev Distance and quantum computing. A comparative analysis of these methods is carried out with a focus on their performance, especially the accuracy of the test results. This study was conducted using a dataset of medical records of patients with anemia. The dataset was taken from Kaggle. This dataset includes five attributes used to predict anemia disease patterns. The dataset was tested using the classical method and K-Medoids with a quantum computing approach that utilizes the Chebyshev Distance calculation. The results of this study reveal a new alternative model for the K-Medoids algorithm with the Chebyshev Distance calculation influenced by the integration of the quantum computing framework. Specifically, the simulation test results show the same accuracy as the classical K-Medoids method and the K-Medoids method with a quantum computing approach with Chebyshev Distance calculations with an accuracy of 80%. The conclusion of this study highlights that the performance of the K-Medoids method with a quantum computing approach with Chebyshev Distance calculations can be implemented to predict anemia using the clustering method.

Abstract

Lung cancer is a leading cause of cancer-related deaths worldwide, and early detection plays a crucialrole in improving treatment outcomes. This study proposes an enhancement of the K-Medoids clusteringmethod by integrating a quantum computing approach using Manhattan distance to improveprediction accuracy for lung cancer diagnosis. The research was conducted using a publicly availablelung cancer dataset consisting of 309 patient records with 14 diagnostic attributes. Comparative experimentswere carried out between the classical K-Medoids and the quantum-enhanced K-Medoids, withperformance evaluated based on clustering accuracy, precision, recall, and F1-score. The results showthat the quantum-based method has the same accuracy as the classical method, namely 88%. Thissuggests that quantum-based clustering can match the accuracy of classical methods after adequatetraining, although consistency and parameter stability remain areas for further refinement. Furtherresearch is recommended to test the model on larger datasets and to explore real-world deployment inclinical decision support systems.

Abstract

Quality of Service (QoS) di dalam sebuah layanan jaringan menjadi faktor terpenting untuk memastikan kapasitas transfer paket data. Salah satunya pemilihan protokol routing yang akan digunakan. Routing Protokol Open Short Path First (OSPF) menggunakan metode Cost Manipulation mampu menjadi sebuah alternatif solusi untuk mamastikan QoS di dalam layanan jaringan dikarenakan metode Cost Manipulation mampu memilih jalan terbaik menuju network tujuan tanpa mempertimbangkan kembali metrik yang seharusnya, baik shortest path ke network tujuan ataupun bandwidth-nya. Hasil pengujian tracerroute sebelum pengimplementasian OSPF cost manipulation didapatkan hanya menggunakan 1 (satu) single line saja dan packet loss yang didapatkan saat terjadinya link failure dengan pengiriman 907 packet data adalah 1,4 packet loss. Sedangkan setelah pengimplementasi OSPF cost manipulation dapat menggunakan 2 (dua) dual line sebagai load balancing dan packet loss yang didapatkan menurun dengan hasil rata-rata sebesar 0,6 packet loss dan pengimplementasian cost manipulation mampu membagi transfer paket data dengan sama rata.

Abstract

Acquired Immunodeficiency Syndrome (AIDS) caused by the Human Immunodeficiency Virus (HIV) is one of the deadliest infectious diseases in the world. Understanding its spread and epidemiological characteristics is crucial for developing and preventing more effective treatments. This study uses the K-Medoids method with a quantum computing approach to predict AIDS based on clinical and demographic data. K-Medoids is chosen to group large amounts of data using a clustering technique that determines the center point (medoid) of each cluster, minimizing the overall distance between data in a cluster. The Manhattan distance is used because it is easier to process data. The quantum computing approach is used to overcome the limitations of classical computing when processing large-scale medical data. This study shows that the application of quantum algorithms to the K-Medoids method allows for faster and more accurate predictions in the diagnosis of AIDS. The tests carried out showed that the prediction accuracy of classical and quantum methods was comparable, namely 85%. The results support the great potential of quantum computing to improve the efficiency of medical predictions. The research involves converting data into quantum format, processing it with the K-Medoids algorithm, and evaluating its performance based on metrics such as intercluster distance and computation time. The research will also identify patterns and risk factor for the spread of AIDS that can be used to develop more effective health interventions. The conclusion of the research is that integrating the K-Medoids techniques can only increase the speed of data processing but also provide competitive accuracy compared to traditional techniques. This research opens up new possibilities in medical data analysis, especially when managing large and complex data sets. The bottom line is that these findings can help make better medical decisions and strategically support AIDS prevention and treatment efforts.

Abstract

PT Indomitra Global is a company engaged in electrical contracting services and provides various types of electrical panels needed by clients. Electrical panels require many important materials, for example mcb, sockets, cables, and many other important components. The material inventory system carried out at PT Indomitra Global still uses a manual method in the material inventory system. This process has several obstacles, namely not having a centralized database that makes material inventory data vulnerable to loss and there are often differences in the suitability of the amount of material in the warehouse with the amount in Microsoft Excel, because data management is still not easy enough and due to human error or input errors. On the basis of this problem, a web-based material inventory application was made using the Rapid Application Development (RAD) method. The material inventory system produced in this study is able to handle material data management which previously was still not easy enough to do, such as searching for data, managing incoming and outgoing material transaction data and making it easier to generate incoming and outgoing material reports based on time periods
