Ardiansah, Dian, Setiawan, Wahdan Budi
Abstract: The seminar titled Visual Discourse in Marketing UMKM Products held in Sukajadi Village, Lemahsugih District, aimed to enhance local entrepreneurs’ understanding of visual communication strategies in product marketing. This… This initiative responded to the limited use of visual elements such as packaging design, symbols, and graphic narratives that reflect local identity and influence consumer perception. Through a participatory approach, participants were introduced to the basics of visual discourse, practiced culturally rooted design techniques, and simulated digital promotional content. Monitoring was conducted through direct observation and feedback, while evaluation involved pre-tests, post-tests, and analysis of participants’ design outputs. Results showed a significant improvement in visual literacy and readiness to redesign product packaging more effectively. The seminar laid a foundation for building a creative and context-sensitive UMKM ecosystem, where visual elements serve as key tools to strengthen product identity, cultural relevance, and market competitiveness.

EVALUATION OF COASTAL SAFETY STRUCTURES IN MITIGATING WAVE OVERTOPPING: A LABORATORY SIMULATION APPROACH

Aulia, Nur, Alham, Irawan, Paharuddin, Paharuddin
Abstract: This research evaluates the performance of coastal safety structures in mitigating wave runoff through laboratory-scale simulations. Pancana Beach in Barru Regency, South Sulawesi, was selected as the research site due to… o its vulnerability to wave-induced beach damage. To simulate wave conditions, a wave generator was designed using a 12-volt DC motor integrated into an acrylic wave bath. This research analyses the effectiveness of three types of coastal safety structures: reflectors, sea walls and sloping sea walls. Laboratory experiments measured the wave overflow volume for each type of structure under controlled conditions. The results showed that reflector-type structures achieved the highest efficiency in mitigating wave overtopping, with an average minimum overtopping value of 0.006 m³/ms. The findings emphasise the importance of selecting and designing appropriate coastal protection measures to minimise coastal erosion, protect coastal infrastructure and reduce risks to surrounding settlements. This study contributes valuable insights into the role of engineered structures in enhancing coastal resilience, especially for areas vulnerable to high wave energy.

AI-DRIVEN HYBRID ENCRYPTION FOR SECURE ELECTRONIC MEDICAL RECORDS

Prayitno, Edy, Heri Winarno, Basuki, Setyowati, Sri, Sutono, Sutono, Riyadi, Riyadi
Abstract: Abstract: In the era of sensitive health data and frequent cyberattacks, securing electronic medical records (EMR) has become a critical challenge. This study proposes a hybrid encryption framework combining Affine and AES… ES algorithms with an AI-based key management module to enhance EMR security while maintaining efficiency. A dataset of 1,000 simulated records was evaluated using five cryptographic configurations: Affine-only, AES-only, RSA-only, Affine–AES, and Affine–AES with AI. Performance was measured through encryption/decryption latency and ciphertext size, while security was assessed under brute-force, SQL injection, and phishing simulations. The AI decision tree for key generation was evaluated using accuracy, precision, recall, F1-score, and entropy metrics. Results show that the AI-enhanced hybrid method eliminates brute-force success, introduces only minor latency overhead, and generates high-entropy keys with reliability above 98%. These findings indicate that integrating AI-based dynamic key regeneration into hybrid encryption can improve EMR security while remaining practical for clinical and cloud-based healthcare systems. Future work should involve real clinical datasets and explore post-quantum cryptographic extensions.             Keywords: AI key management; attack resistance; encryption performance; electronic medical records; hybrid encryption     Abstrak: Di era meningkatnya sensitivitas data kesehatan dan maraknya serangan siber, perlindungan Rekam Medis Elektronik (RME) menjadi tantangan penting. Penelitian ini mengusulkan kerangka enkripsi hibrida yang menggabungkan algoritma Affine dan AES dengan modul manajemen kunci berbasis AI untuk meningkatkan keamanan RME tanpa mengorbankan efisiensi. Dataset simulasi berisi 1.000 entri diuji menggunakan lima konfigurasi kriptografi: Affine-only, AES-only, RSA-only, Affine–AES, serta Affine–AES dengan AI. Performa diukur melalui latensi enkripsi/dekripsi dan ukuran ciphertext, sedangkan keamanan dievaluasi melalui simulasi serangan brute force, SQL injection, dan phishing. Model decision tree untuk manajemen kunci dinilai menggunakan metrik akurasi, presisi, recall, F1-score, dan entropi. Hasil menunjukkan bahwa metode hibrida dengan AI menghilangkan keberhasilan brute force, menambah overhead latensi yang minimal, serta menghasilkan kunci berentropi tinggi dengan reliabilitas di atas 98%. Temuan ini menunjukkan bahwa regenerasi kunci dinamis berbasis AI dalam skema enkripsi hibrida dapat meningkatkan keamanan RME sekaligus tetap praktis untuk sistem klinis dan layanan kesehatan berbasis cloud. Penelitian selanjutnya disarankan menggunakan dataset klinis nyata dan mengeksplorasi kriptografi pascakuantum.   Kata kunci: enkripsi hibrida; ketahanan serangan; kinerja enkripsi; manajemen kunci berbasis AI; rekam medis elektronik

Abstract: Abstract: Medan Aviation Polytechnic is one of the campuses under the ministry of transportation which has a major in telecommunication and air navigation engineering in Indonesia. Based on field surveys, an Analog to Digital… gital Converter (ADC) practicum kit is needed to improve the ability of cadets. Based on this background, this study aims to design and simulate two ADC circuits, each of which is compiled by the integrated circuit (IC) ADC0804 and IC ADC0809 respectively. Three statistical formulas, namely mean error (ME), standard deviation error (SDE), and root mean square error (RMSE) are used to measure the performance of the two ADC circuits. Both ADC circuits are simulated using a Proteus 8.11 Simulator with 255 analog input voltages. Based on the result of the study, it is known that the ADC circuit compiled by IC ADC0809 is more accurate than the ADC circuit compiled by IC ADC0804. This is evidenced by a smaller error value, which is based on the simulation results of the ME, SDE, and RMSE values were 0.4210, 0.3410, and 0.5110, respectively. And, based on the measurement results, it has ME, SDE, RMSE respectively, namely 0.8510, 0.8110, and 0.9310.             Keywords: ADC; Proteus 8.11 Simulator; IC ADC0804; IC ADC0809; ME; SDE; RMSE     Abstrak: Politeknik Penerbangan Medan adalah salah satu kampus di bawah Kementerian Perhubungan yang memiliki jurusan teknik telekomunikasi dan navigasi udara di Indonesia.
