Abstract

Edge-Internet of Things (Edge IoT) systems are increasingly integral to applications that require real time signal processing, particularly where low latency and energy efficiency are critical. This paper explores the design and performance evaluation of a heterogeneous microprocessor architecture aimed at optimizing energy consumption and real time performance. The heterogeneous architecture integrates multiple types of cores, such as Central Processing Units (CPUs), Digital Signal Processors (DSPs), and Graphics Processing Units (GPUs), to allocate tasks based on computational demand. The proposed design significantly reduces energy consumption, particularly during high-performance tasks, while maintaining real time processing guarantees. Simulation-based performance evaluation was conducted to assess the energy efficiency, latency, and overall system performance under varying workloads, including real time Digital Signal Processing (DSP) benchmarks. The results showed that the heterogeneous architecture outperformed traditional homogeneous processors, demonstrating up to a 19-fold improvement in energy efficiency. Furthermore, the system reduced latency by up to 45% in real time applications, making it particularly suitable for Edge IoT environments such as industrial automation and smart healthcare, where both performance and energy efficiency are critical. Despite some trade-offs in task scheduling complexity, the heterogeneous design was able to balance power consumption and computational performance effectively. The findings suggest that this architecture can serve as a foundation for future Edge IoT systems, providing significant advantages in terms of energy efficiency, real time processing, and scalability. Future work will focus on further optimization of the architecture and exploring its application across various IoT environments.

Abstract

Kesenjangan literasi digital masih menjadi tantangan bagi warga binaan lembaga pemasyarakatan, padahal kemampuan memahami dan memanfaatkan teknologi informasi merupakan bekal penting untuk reintegrasi sosial dan kemandirian ekonomi pasca-pembinaan. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi digital dasar melalui pengenalan konsep website bagi warga binaan Lapas Kelas II A Salemba sebagai mitra pelaksanaan. Sasaran kegiatan adalah 30 warga binaan yang dipilih bersama pihak pembinaan Lapas. Metode pelaksanaan menggunakan pendekatan participatory community-based learning melalui empat sesi terstruktur: pengenalan literasi digital dan fungsi website, pemahaman struktur website, simulasi pembuatan website sederhana berbasis CMS offline (WordPress), serta diskusi reflektif. Evaluasi efektivitas dilakukan menggunakan desain one-group pretest–posttest dengan instrumen kuesioner, observasi, dan wawancara. Hasil menunjukkan peningkatan rata-rata pemahaman peserta dari nilai pretest 45,3 menjadi 82,1 pada posttest, dengan nilai N-Gain sebesar 0,81 (kategori tinggi), serta korelasi positif yang kuat (r = 0,72) antara keaktifan peserta dan peningkatan pemahaman. Secara kualitatif, peserta melaporkan meningkatnya rasa percaya diri, motivasi belajar teknologi, dan pemahaman potensi website untuk aktivitas produktif setelah bebas. Kegiatan ini dinilai berhasil dan direkomendasikan untuk dilanjutkan sebagai program pelatihan lanjutan pembuatan website produktif bagi warga binaan
