Abstract

This study investigates the performance of a standalone digital communication system based on Orthogonal Frequency Division Multiplexing (OFDM) for digital image transmission over Additive White Gaussian Noise (AWGN) channels. The system was tested using two digital modulation techniques: Binary Phase Shift Keying (BPSK) and Quadrature Phase Shift Keying (QPSK). Unlike previous studies that focused on OFDM implementation in large-scale communication systems such as cellular networks, this research explores a simplified standalone scenario without any supporting network infrastructure. Simulations were carried out in the MATLAB environment using grayscale image inputs ranging from 1 MB to 10 MB, with signal-to-noise ratio (SNR) levels varying from 0 to 30 dB. The results show that BPSK modulation maintains a low Bit Error Rate (BER) of approximately 0.077 even under low SNR conditions (as low as 0 dB). In contrast, QPSK modulation achieves optimal performance when the SNR reaches at least 15 dB, where the BER drops to 0.00000. The image size did not significantly affect system performance, indicating robustness across varying data loads. Overall, the findings suggest that BPSK provides higher reliability in noisy channels, whereas QPSK offers better spectral efficiency under cleaner conditions. Therefore, the proposed standalone OFDM system demonstrates strong potential for lightweight data communication applications such as sensor networks and remote monitoring systems operating in limited network environments.

Abstract

This study presents a real-time human detection and face recognition system that utilizes CCTV video streams and a localhost-based monitoring dashboard. Using a Research and Development (R&D) approach, a computer vision application was designed and implemented on a laptop platform. Human detection was performed using YOLO11n, facial regions were localized with YuNet, and face recognition was carried out using SFace to distinguish registered individuals from unknown persons. The detection results were displayed through a web-based dashboard that provided live video streaming, AI status information, face registration, and detection history records. Performance evaluation was conducted under various conditions, including human and non-human scenarios, registered and unknown faces, dark-room environments, and night-vision mode. The dashboard maintained a preview rate of approximately 20–30 FPS. Experimental results showed that human detection achieved an accuracy of 80%, while face recognition achieved 72% accuracy under the tested conditions. Alert Level 1 was triggered when a person was detected, whereas Alert Level 2 was activated for unknown-face events. The findings demonstrate the potential of integrating lightweight computer vision models into a local surveillance system without relying on cloud infrastructure. Nevertheless, system performance remained dependent on factors such as lighting conditions, camera distance, face orientation, image quality, and available computing resources.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) hold a strategic role in the national economy but continue to face challenges in accessing international markets, securing funding, managing legal compliance, and understanding export procedures. The UMKM Go Export Seminar with Bank Sumsel Babel 2025 was conducted to strengthen the capacity of MSME actors to penetrate the global market, featuring speaker Dewi Ekha Harlasyanti, S.H. This activity aimed to provide knowledge on export strategies for local products, optimization of digital marketing, legal business management, and appropriate product packaging for export standards. The seminar was conducted using a descriptive qualitative observational method through discussion sessions, material presentations, and participant satisfaction evaluations. The target audience consisted of MSMEs in the South Sumatra, focusing on improving product competitiveness for export purposes. The seminar resulted in increased understanding among participants regarding small-scale export opportunities, flexible payment systems, strategies for finding international buyers through social media, and the importance of mastering product specifications. The involvement of Bank Sumsel Babel in offering financial support further facilitated better access to capital for MSMEs. This activity contributed to improving the readiness of local MSMEs to initiate the export process progressively, thereby enhancing the region’s product contribution to global trade.

Abstract

The alignment between educational and industrial needs is an important factor in driving economic growth and workforce readiness. In South Sumatra Province, vocational high schools and polytechnics play a crucial role in equipping students with the technical and practical skills necessary for employment in key sectors such as plantations, feed, oil and gas, and coal-based industries. However, there is a gap between the competencies offered by educational institutions and the demands of the growing industry, especially in emerging areas such as digital transformation and sustainability. This study aims to map the competence of vocational schools and polytechnics to leading industries in South Sumatra using Geographic Information Systems (GIS) and input-output analysis. GIS is used to analyze the spatial distribution of educational institutions and their proximity to industrial centers, while input-output analysis assesses competency flows into industry-specific needs. Data on educational programs, graduate output, and industry requirements are compiled and analyzed to identify gaps and areas for improvement. The results reveal strong alignment in traditional industries such as rubber, palm oil, and mining, while significant gaps are observed in emerging areas such as green energy and digital technologies. Urban areas such as Palembang were found to have a higher concentration of educational institutions and diverse programs, while rural areas faced limited access to specialized training. The study emphasizes the importance of modernizing curriculum, investing in infrastructure, and encouraging industry-education collaboration to address these gaps.
