Abstract

Energi listrik merupakan salah satu energi yang banyak dimanfaatkan dalam menjalankan segala aktivitas manusia. Konsumsi energi listrik yang tidak terkendali dapat menjadi potensi pemborosan yang dapat merugikan dari segi ekonomi dan lingkungan. Berdasarkan permasalahan tersebut, dirancang suatu sistem pemantau konsumsi energi listrik berbasis Internet of Things (IoT) untuk memantau konsumsi energi listrik. Sistem ini tersusun dari sensor arus, energy meter iEM3255, Mikrokontroller ESP32, perangkat LoRa, dan suplai daya. Komponen – komponen tersebut diintegrasikan menggunakan komunikasi ModBus dan hasil pengukuran dapat dilihat melalui aplikasi smartphone yang dibuat menggunakan platform Kodular. Berdasarkan hasil implementasi dan pengukuran arus, tegangan, dan daya diperoleh nilai error sebesar 3,84%. Berdasarkan hasil tersebut dapat disimpulkan perangkat Energy Meter iEM3255 dapat diintegrasikan dengan sistem pemantau konsumsi energi listrik berbasis IoT dengan menyesuaikan kapasitas beban yang terpasang.   Kata kunci: Sistem Pemantau Energi Listrik, Energy Meter, Komunikasi ModBus, IoT.

Abstract

Energy inefficiency due to Air Conditioners (AC) running in empty rooms contribute to unnecessary energy consumption and increased CO₂ emissions. This study explores how different depth levels of the YOLOv8 architecture and dropout regularization can enhance human density detection for smarter AC control systems. By evaluating model accuracy through Mean Average Precision (mAP50-95), we provide quantitative insights into how these modifications improve detection performance. Our dataset consists of 1363 images taken in an office environment at ITERA under varying lighting conditions and different human presence densities. The results show that the YOLOv8m model performs best, achieving an mAP50-95 score of 0.814 in training and 0.813 in validation, outperforming other YOLOv8 variants. Furthermore, applying dropout regularization improves model generalization, increasing mAP50-95 from 0.552 to 0.6 and effectively reducing overfitting. This study highlights the balance between architectural depth and dropout regularization in YOLOv8, demonstrating its effectiveness in energy-efficient smart buildings. The findings support the potential of deep learning-based human density detection in improving energy conservation strategies, making it a valuable solution for intelligent automation systems.

Abstract

This community service program addressed productivity instability in oyster mushroom cultivation and limited utilization of digital and renewable-energy-based village infrastructure in Karang Anyar Village, South Lampung. The program aimed to strengthen agricultural productivity and support Smart Village development through training and implementation of Internet of Things (IoT) and renewable energy technologies. The activities included participatory needs assessment, installation of an IoT-based automatic misting system in mushroom houses, deployment of solar-powered lighting systems for the village sports field, and training on Content Management System (CMS)-based website management involving mushroom farmers, village administrators, and university students participating in the Community Service Program (KKN). Functional testing showed that the IoT-based misting system achieved 100% operational performance, while training activities involved seven mushroom farmers with more than 50% of participants demonstrating adequate understanding of system operation and digital platform utilization. In addition, the installation of solar-powered lighting improved the accessibility of village sports facilities at night. These results demonstrate that integrating IoT and renewable energy technologies effectively supports Smart Village development and strengthens sustainable community-based innovation in rural areas.
