Abstract

Purpose – This study implements the YOLOv9 architecture to automatically classify the health condition of ganyong leaves (Canna edulis Kerr.) as an early-detection tool for leaf spot disease. The study addresses the limitations of subjective manual identification and supports farmers in Bumipajo Village, Bima Regency, in reducing potential crop failure. Methods – A primary field dataset consisting of 1,383 image objects was collected and divided into training, validation, and testing sets using a 70:20:10 ratio. YOLOv9 was implemented by integrating Programmable Gradient Information (PGI) and the Generalized Efficient Layer Aggregation Network (GELAN). Model training was conducted in Google Colab using GPU acceleration, a batch size of 4, and 50 epochs. Findings – Evaluation on independent test data showed strong detection performance, with mAP@50 of 99%, Precision of 99%, Recall of 100%, and an average inference speed of 58.4 ms per image. These results indicate that YOLOv9 can effectively preserve disease-related morphological features in visually complex biological objects. Research implications – The findings are limited to the environmental conditions of the data collection site and one disease type. The reported time efficiency also depends on GPU-based hardware and requires further validation on mobile devices. Originality – This study contributes a field-based primary dataset of ganyong leaves and validates YOLOv9 for a local agricultural commodity that remains underexplored.

Abstract

Purpose – Livestock farming is a vital sector of the Indonesian economy, yet the common practice of allowing livestock to roam freely renders manual monitoring inefficient and exposes farmers to risks of loss, accidents, and theft. This study presents an IoT-based livestock monitoring prototype designed to enable real-time location tracking and automated boundary violation alerts, addressing the lack of affordable and practical smart monitoring solutions for smallholder farmers. Methods – The system was developed using an ESP32 microcontroller integrated with a Neo-6M GPS module and a Telegram bot for automatic notifications. A geofencing boundary of 50 meters was configured from a fixed reference point. Twelve trials were conducted across morning, afternoon, and evening sessions to evaluate system performance under varying conditions. Findings – The system delivered location alerts every ten minutes with Google Maps links and coordinates. Under normal conditions, livestock positions were detected within 5.0–12.7 meters of the reference point. Boundary violations exceeding 50 meters triggered immediate alerts, with notification latency ranging from 3 to 8 seconds under stable network conditions. GPS baseline error was approximately 5.0–5.5 meters, with an accuracy variation of ±2–3 meters. Research Implications – System performance is constrained by Wi-Fi network stability and environmental factors affecting GPS accuracy, limiting its generalizability to areas with reliable connectivity. Further field testing is required before broader implementation. Originality – This study contributes a low-cost, ESP32-based geofencing solution integrated with Telegram, offering a practical and scalable approach to smart livestock monitoring in developing agricultural contexts.

Abstract

Purpose - This study aims to develop an Internet of Things (IoT)-based Smart Energy System integrated with the Support Vector Machine (SVM) algorithm for real-time electricity consumption anomaly detection. The study addresses the increasing need for intelligent energy monitoring systems capable of identifying abnormal electricity consumption patterns efficiently and accurately in smart homes and smart building environments. Methods - This research employed a quantitative experimental approach using the Cross Industry Standard Process for Data Mining (CRISP-DM) framework. Electricity consumption data were collected using ESP32-based IoT devices integrated with ACS712 current sensors and ZMPT101B voltage sensors. Data preprocessing included cleaning, normalization using the Min-Max Scaling method, and anomaly labeling based on predefined energy consumption thresholds. The Support Vector Machine algorithm with a Radial Basis Function (RBF) kernel was implemented for anomaly classification. The dataset consisted of 25,000 electricity consumption records collected over 30 days, comprising 81.4% normal data and 18.6% anomaly data. Hyperparameter optimization was performed using Grid Search Cross Validation with 10-fold cross-validation. Findings - The experimental results demonstrate that the proposed SVM model achieved an accuracy of 96.80%, precision of 95.10%, recall of 94.90%, F1-score of 95.00%, and ROC-AUC of 97.20% in detecting electricity consumption anomalies. In addition, the MQTT-based IoT communication system achieved a data transmission success rate of 98.70% with low communication latency. Comparative evaluation results showed that the SVM algorithm outperformed Decision Tree, K-Nearest Neighbor, and Random Forest methods across all evaluation metrics. Implications - The proposed system contributes to the development of intelligent energy monitoring solutions capable of supporting real-time anomaly detection, reducing energy waste, and improving operational efficiency in smart energy environments. The lightweight computational characteristics of SVM also make the proposed approach suitable for IoT devices with limited computational resources. However, further testing using industrial-scale datasets is required to improve system generalization and large-scale deployment capability. Originality - This study presents an integrated smart energy architecture combining IoT-based real-time monitoring, MQTT communication, database systems, and SVM-based anomaly detection within a unified intelligent energy management framework.
