Abstract

Kebutuhan akan keamanan atas data merupakan hal yang sangat penting dalam era digital saat ini, terutama pada proses pertukaran data yang bersifat sensitif terhadap serangan siber. Selain keamanan data, ukuran data yang semakin besar juga menjadi permasalahan dalam proses pertukaran file karena waktu yang dibutuhkan dalam pemrosesan juga semakin lama. Penelitian ini melakukan implementasi skema hybrid cryptography menggunakan algoritma Camellia dan Dual Modulus RSA yang bertujuan untuk mengatasi permasalahan-permasalah tersebut. Pemilihan skema hybrid cryptography adalah untuk mendapatkan kekuatan dari masing-masing algoritma, sehingga keamanan dan kecepatan dari tiap algoritma dapat didapatkan. Tahapan yang dilakukan dalam penelitian ini adalah studi literatur, perancangan, implementasi dan pengujian. Hasil dari pengujian yang telah dilakukan, diperoleh bahwa untuk proses pembangkitan kunci skema hybrid memiliki waktu tempuh yang mirip dengan algoritma DM-RSA dengan perbedaan 9.3% lebih cepat dan pada proses enkripsi dan dekripsi memiliki waktu tempuh yang mirip dengan algoritma Camellia dengan perbedaan 2.3% lebih cepat. Untuk keseluruhan proses algoritma hybrid memiliki waktu tempuh yang mirip dengan algoritma Camellia untuk skenario ukuran data 600MB dan 1200MB dengan perbedaan 25.2% lebih lambat.

Abstract

Penelitian ini bertujuan untuk meningkatkan akurasi dalam klasifikasi plankton secara otomatis dengan pendekatan hibrida CNN-ELM. Menggunakan Convolutional Neural Network (CNN) untuk ekstraksi fitur dan Extreme Learning Machine (ELM) sebagai pengklasifikasi, model ini dirancang untuk mengatasi tantangan citra plankton yang buram, dataset kecil, dan ketidakseimbangan kelas. SMOTE digunakan untuk menangani ketidakseimbangan data. Dari implementasi SMOTE dengan metode interpolasi, permasalahan ketidakseimbangan kelas berhasil diatasi dengan menjadikan jumlah data latih sama rata untuk setiap kelas. Dari hasil pengujian, konfigurasi dengan 32 filter dan 2000 hidden node serta 64 filter dan 2000 hidden node memberikan performa terbaik dengan akurasi 97,78%. Sebaliknya, model dengan 64 filter dan 4000 hidden node menunjukkan performa terendah dengan akurasi 82,78% yang diakibatkan overfitting. Analisis confusion matrix mengungkapkan kinerja tinggi pada beberapa kelas plankton, namun masih kesalahan klasifikasi sering terjadi pada kelas seperti Alexandrium, Noctiluca, dan Nitzschia. Temuan ini menunjukkan bahwa konfigurasi dengan filter dan node yang lebih kompleks tidak selalu menghasilkan kinerja lebih baik. Penelitian ini diharapkan dapat mendukung pengambilan keputusan di bidang kelautan.

Abstract

 Intellectual disability (ID) is a neurodevelopmental disorder that requires early and accurate diagnosis. This study aims to improve the efficiency of ID diagnosis using a machine learning approach. A Support Vector Machine (SVM) model optimized with Grey Wolf Optimizer (GWO) was developed and trained using data from questionnaires completed by 101 families/guardians of ID patients at RSUD Dr. Soetomo Surabaya. The features used include family history, cognitive abilities, and adaptive behaviors. The results showed that the GWO-SVM model achieved an accuracy of 95% in classifying ID patients, an improvement of 5% compared to the conventional SVM. The GWO algorithm successfully optimized the parameters in SVM, resulting in a model with the best performance. These findings indicate the potential of GWO-SVM as an effective and efficient tool for assisting in the diagnosis of ID.

Abstract

Perkembangan teknologi kecerdasan buatan telah menghasilkan berbagai inovasi multimedia, salah satunya adalah deepfake. Teknologi ini memanfaatkan algoritma deep learning untuk memanipulasi citra dan video secara realistis, sehingga sulit dibedakan dengan konten asli. Meskipun memiliki manfaat di bidang hiburan, deepfake juga menimbulkan ancaman serius terhadap keamanan digital. Penelitian ini bertujuan mendeteksi citra deepfake menggunakan arsitektur Convolutional Neural Network (CNN) dengan integrasi Dilated convolution. Integrasi ini memperluas receptive field tanpa meningkatkan jumlah parameter, sehingga model dapat menangkap informasi global dan detail lokal secara bersamaan. Dataset yang digunakan adalah Kaggle Deepfake Dataset berisi 8.000 citra (4.000 asli dan 4.000 palsu). Model diuji dengan lima rasio pembagian data (50:50 hingga 90:10) dan dibandingkan dengan CNN konvensional. Evaluasi menggunakan Confusion matrix dengan metrik akurasi, presisi, recall, dan F1-score. Hasil terbaik diperoleh pada rasio 80:20 dengan akurasi 85,69%, presisi 85,82%, dan recall 85,90%. Model CNN-Dilated secara konsisten mengungguli CNN standar dengan peningkatan akurasi 1–3% pada berbagai skenario. Hasil ini membuktikan efektivitas Dilated convolution dalam meningkatkan performa deteksi citra deepfake, yang berpotensi diterapkan dalam bidang keamanan digital dan forensik media.

Abstract

Natural disasters in archipelagic regions often disrupt communication networks, particularly in geographically isolated islands where terrestrial infrastructure is limited and highly vulnerable. Hence, adaptive, infrastructure-independent solutions are required to maintain connectivity during emergencies. The research proposes an adaptive routing protocol for Delay Tolerant Network (DTN), named Q-learning-based Forwarding Routing (QFR), designed to enhance data delivery performance in disaster scenarios characterized by intermittent connectivity and constrained resources. QFR employs a lightweight, tabular Q-learning framework to make intelligent forwarding decisions based on real-time state information, including buffer occupancy, encounter history, and local node density. The protocol further integrates adaptive replica control and prioritybased scheduling mechanisms to regulate congestion and optimize bandwidth and buffer utilization. Performance evaluation is conducted using the ONE Simulator with realistic maritime mobility traces derived from vessel movement patterns around Madura Island, Indonesia, representing inter-island emergency communication conditions. The results indicate that QFR consistently outperforms benchmark protocols such as Epidemic and PRoPHETv2, particularly in maintaining a high delivery ratio under heavy traffic loads while keeping routing overhead moderate and latency stable. Time-series analysis further demonstrates QFR’s ability to improve its performance over time as the agent learns. The key finding is that a lightweight, adaptive algorithm based on a tabular Q-learning framework provides a practical and effective solution for reliable communication in resource-constrained emergency networks, avoiding the computational complexity of deep reinforcement learning approaches.

Abstract

Traditional communication infrastructures are vulnerable to failure during natural disasters in dense urban areas, hindering early warning dissemination. Delay Tolerant Network (DTN) offers a resilience, yet most studies relies on simulations, overlooking physical layer constraints affecting on opportunistic routing in real-world urban scenarios. This study addresses that specific gap by empirically validating a DTN-LoRa prototype-based communication system for flood data monitoring in Surabaya. A 4-node field test simulated the Store-Carry-Forward mechanism. A fixed node in the Dukuhpakis flood zone (TMP) transmitted bundles to mobile nodes on public transport routes (FD9, FD4). These data mules relayed the bundles via an opportunistic contact at Marmoyo Shelter, delivering them to a gateway node at the BPBD Command Post (PMI Surabaya). Performance was evaluated by Packet Delivery Ratio (PDR) and Latency under varying LoRa parameters (Spreading Factor, Coding Rate). The experiment validated the functional DTN architecture, achieving 100% PDR in the optimal configuration (SF7, CR4/7). The key finding was a "Contact Window Bottleneck" as a critical failure factor. LoRa configurations with high Time on Air (ToA) failed to transfer the entire data bundle within the narrow opportunistic contact window between mobile nodes, causing PDR to drop as low as 60%. Implementation success depends on the physical layer throughput that must be high enough to complete data transfer during brief opportunistic contacts, rather than merely maximizing signal range. These findings provide a critical performance baseline for disaster management agencies, demonstrating a feasible, low-cost architecture that can enhance the reliability of urban disaster response communication.

Abstract

The advancement of digital technology provides opportunities to innovate learning methods, especially for subjects like history that are often considered less engaging. This study develops a 2D Adventure RPG educational game themed on the November 10 Battle, integrating branching narrative and lane tower defense minigames to enhance students’ historical understanding. This integration addresses a research gap, as few studies have combined branching narrative and lane tower defense in a historical educational RPG. The game allows players to make choices affecting the storyline while facing strategic challenges through interactive mechanics. The study employed a single-group pre-test–post-test design involving 23 students from SMP Negeri 6 Surabaya. Results showed a significant improvement in learning outcomes, with the average score increasing from 53.48 to 94.78 and standard deviation decreasing from 19.21 to 5.93. The Wilcoxon Signed Rank test yielded p = 0.000 (< 0.05), confirming statistical significance. User experience evaluation using GUESS-18 indicated positive responses (mean scores 3.78–4.02), with branching narrative (4.06) and lane tower defense (3.94) receiving favorable feedback. Validity tests confirmed all items were valid (r > 0.413; p < 0.05), and reliability was high (Cronbach’s Alpha = 0.867). However, the small sample size (23 students) may limit generalizability of the findings. These findings suggest the November 10th educational game effectively improves historical understanding, cognitive and affective engagement, learning motivation, and strategic thinking. The study highlights gamified learning as an engaging alternative for history education in the digital era.

Abstract

The rapid advancement of digital technology has created new opportunities for integrating interactive media into history education, a subject often perceived as passive and less engaging. Addressing the lack of educational games that combine narrative with strategic simulation, this study develops and evaluates Medan Area Battle, a 2D action role-playing game that introduces a dual-pedagogical mechanism through branching narrative and turn-based tactical combat. This integration is designed to allow students to experience historically grounded decision-making while simultaneously engaging in strategic reasoning with the events of the Medan Area Battle. A design-based research framework guided the development process through requirement analysis, design, implementation, and user testing. The evaluation involved twenty-five junior high school students, providing insight into the game's effectiveness. Learning performance was measured through pre-test and post-test assessments, while user experience was examined using Game User Experience Satisfaction Scale-18 (GUESS-18). Two additional dimensions Branching Narrative and Tactical Combat were incorporated to capture the unique interaction patterns introduced by the game’s narrative and strategic systems. Statistical analysis employed the Shapiro–Wilk test, Wilcoxon Signed Rank test, and Cronbach’s Alpha reliability testing. Results indicated a significant improvement in learning outcomes, with mean scores rising from 60.80 to 85.60 (p = 0.000767). The overall GUESS-18 rating of 4.15 (“Very Good”), alongside high scores in Educational (4.30) and Tactical Combat (4.27), suggests strong user engagement. These findings demonstrate that integrating narrative choice with tactical gameplay offers effective and theoretically grounded approach enhancing students’ cognitive understanding and motivation in history learning.
