Abstract

This research presents the design of a compact dual-port UWB MIMO antenna. The primary challenge in designing UWB MIMO antennas lies in achieving a low-frequency band of 3.1 GHz while maintaining a small size. By modifying the patch shape to a tapered configuration and incorporating an inset feed and a slit for WLAN notch band, a rectangular monopole patch antenna successfully overcomes these limitations. The MIMO configuration of this antenna achieves a wide UWB bandwidth of 3.1-12 GHz with a compact dimension of 20×28.5×1.6 mm. The antenna exhibits excellent characteristics, including low mutual coupling (-15 dB), maximum gain of 3 dBi, low ECC (<0.01), high diversity gain (<9.95), low TARC (< -20 dB), and nearly omnidirectional radiation pattern. These results demonstrate the suitability of the proposed antenna design for UWB applications.

Abstract

Pendahuluan: prevalensi pernikahan dini di Indonesia memperlihatkan adanya tren penurunan tetapi tetap berada pada angka yang memerlukan perhatian serius dimana proporsi perempuan usia 20-24 tahun yang menikah  sebelum usia 18 tahun masih mencapai 6,92 %. Tujuan: untuk mengeksplorasi peran petugas kesehatan dalam mengidentifikasi faktor penyebab pernikahan dini yang memengaruhi upaya pencegahan pernikahan dini. Metode: Desain kualitatif dengan pendekatan fenomenologi. Informan terdiri dari tiga kepala puskesmas, tiga bidan koordinator, dan satu pejabat BKKBN Kota Medan (n=7). Teknik pengumpulan data melalui wawancara mendalam dan triangulasi sumber Hasil: Ditemukan enam tema: (1) penyebab pernikahan dini, (2) program edukasi, (3) peran orang tua, (4) kolaborasi lintas sektor, (5) pencegahan dini, dan (6) evaluasi program. Akar masalah utama adalah kurangnya model edukasi terintegrasi yang menyasar orang tua remaja 19 tahun. Hambatan meliputi identifikasi yang belum sistematis, kebijakan yang tidak spesifik, keterbatasan sumber daya, kolaborasi yang lemah, dan evaluasi program yang minim. Kesimpulan: Penelitian ini menjelaskan bahwa pentingnya penguatan program berbasis keluarga sebagai strategi utama dalam pencegahan pernikahan dini  dan kerja sama lintas sektor yang lebih strategis.

Abstract

This study examines the influence of relative humidity (RH) on the electrochemical and structural properties of polyvinyl alcohol (PVA) composite films reinforced with MXene, zinc oxide (ZnO), and cellulose nanocrystals (CNC). Composite films were fabricated via solvent casting and conditioned at RH levels of 50%, 75%, and 94%. Cyclic voltammetry and four-point probe tests revealed substantial enhancements in current density, specific capacitance, and bulk conductivity with increasing RH, attributed to improved ionic mobility and interfacial polarization. X-ray diffraction indicated reduced crystallinity due to polymer swelling, while scanning electron microscopy showed enhanced MXene dispersion at higher RH. Fourier-transform infrared spectroscopy confirmed intensified hydroxyl interactions, reflecting increased hydrophilicity. These humidity-induced improvements suggest promising applications in humidity-responsive flexible electronics and sensors. However, potential trade-offs include reduced mechanical stability under prolonged exposure. The findings offer new insights for optimizing hydrophilic polymer composites to enhance environmental adaptability and advanced device performance.

Abstract

This study develops an intrusion detection system optimized with machine learning techniques for efficient and effective detection of Distributed Denial-of-Service (DDoS) attacks. Using the Decision Tree algorithm, the system is designed to maximise accuracy in the identification and classification of DDoS attacks. The CIC-DDoS2019 dataset, which consists of various comprehensive simulated attack scenarios, is used as the basis for training and validation, providing the model with robust capabilities in recognizing DDoS attacks with high accuracy. This IDS successfully achieved a 100% detection rate, which is a significant result in the network security environment. The system is integrated into the existing network infrastructure, monitoring data flows in real-time and performing predictive analysis to detect early indications of attacks. Each attack detection immediately triggers a notification sent via a Telegram bot, ensuring that the security team can react quickly to isolate and address the attack. These notifications include details such as the source, type of attack, detection time, and involved protocol information, enabling more informed and strategic response actions. The use of Telegram bots for real-time communication not only enhances the speed of response to threats but also supports system scalability by facilitating adjustments and integration across various operational scenarios. The system's quick detection and response is a big step forward for machine learning-based intrusion detection systems (IDS). It provides opportunities for further research and practical applications that can adapt to various digital security scenarios.
