Abstract

Accurate classification of rice plant diseases is essential for early intervention and precision agriculture. However, real-world datasets often suffer from complex backgrounds, high-dimensional features, and severe class imbalances, which compromise classification performance. This study proposes an integrated framework combining image segmentation using U-Net, feature selection via Ant Colony Optimization (ACO), hybrid sampling to handle class imbalance, and final classification using a Convolutional Neural Network (CNN). Segmentation isolates disease-affected areas, ACO optimizes feature subsets, and hybrid sampling balances class distribution using undersampling and SMOTE. The proposed method was tested on four rice leaf disease datasets—Brown Spot, Leaf Blast, Leaf Blight, and Leaf Scald—exhibiting significant class imbalance. Experimental results show that the proposed approach outperforms baseline models (SegNet, PspNet, and E-Net) across multiple metrics: Accuracy, IoU, Precision, and Recall. This indicates the framework’s robustness and potential for real-world deployment in precision agriculture. Future work will focus on model compression and real-time implementation in IoT systems.

Abstract

Fruit fly infestations pose a significant threat to agricultural productivity, especially in chili plantations, which can cause substantial yield losses. Accurate and rapid species classification is crucial for implementing targeted pest control strategies. This study developed a computationally efficient fruit fly species classification model using a deep learning approach that focused on improving accuracy with fine tuning and class balancing strategies. The dataset consists of 1049 images across 4 fruit fly species, captured in a natural plantation environment and available at www.inaturalist.org. The model evaluated several lightweight Convolutional Neural Network (CNN) architectures, including MobileNetV3-Small, RegNetY-400MF, and SqueezeNet among others, with RegNetY-400MF emerging as the best performing model, achieving a validation accuracy of 96.10% and a macro F1 score of 95.70%. The models tested in this study included several lightweight Convolutional Neural Network (CNN) architectures, including MobileNetV3-Small, RegNetY-400MF, and SqueezeNet, among others. RegNetY-400MF proved to be the best performing model, achieving a validation accuracy of 96.10% and a macro F1 score of 95.70%. Compared to other state-of-the-art models, RegNetY-400MF demonstrated higher accuracy while maintaining a lower number of parameters (8.3 million) and reduced computational complexity (0.41 GFLOPs). This makes the model highly suitable for real-time applications in resource-constrained agricultural environments. The model offers a practical solution for fruit fly species detection, enabling early and accurate identification of pest infestations in chili plantations, thereby reducing the risk of crop failure. By providing an efficient and scalable pest control tool, the model supports precision pest management, improves yield stability, and contributes to sustainable agriculture.

Abstract

The plant growth and yield could be influenced by the soil ameliorants. This study was to obtain the effect of cow manure, dolomite, and their interactions on the growth and yield of mung bean plants. This study was conducted at Marindal II Village, Patumbak Subdistrict, Deli Serdang District, North Sumatra from February to May 2022. A factorial randomized block design was selected in this study with the first factor being the dosage of cow manure (0; 2.5; 5 tons ha-1) and the second factor was the dolomite lime (0; 1; 2 kg plot-1) within three replications. Data were analyzed using ANOVA and further tested by Duncan at P<0.05. The results showed an increase in dry weight, seed weight plot-1, 100-seed weight, and yield ha-1 of mung bean were found in 5 tons ha-1 of cow manure dose by 19.06%; 103.62%; 6.48%; and 2.04 times. The plant height and dry weight of mung bean as well as soil pH also increased in 2 kg plot-1 of dolomite dose were 24.55; 15.68; and 7.68%. Their interaction of cow manure and dolomite had a slight impact on the growth and yield of mung bean plants

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan produktivitas dan kemandirian peternak ikan air tawar di Desa Mariendal II melalui penerapan sistem feeder dan monitoring pakan ikan berbasis Internet of Things (IoT). Permasalahan utama mitra meliputi pemberian pakan yang masih dilakukan secara manual, ketidakteraturan jadwal pakan, pemborosan pakan, serta keterbatasan literasi teknologi. Metode pelaksanaan kegiatan menggunakan pendekatan partisipatif yang meliputi tahap persiapan, pelatihan dan implementasi sistem IoT, pendampingan, serta evaluasi. Evaluasi dilakukan menggunakan pre-test dan post-test untuk mengukur peningkatan pemahaman dan keterampilan peserta. Hasil kegiatan menunjukkan peningkatan rata-rata kompetensi peserta sebesar 47%, dengan peningkatan tertinggi pada keterampilan instalasi dan pengoperasian perangkat serta kemampuan membaca hasil monitoring pakan. Nilai effect size yang sangat besar menunjukkan bahwa peningkatan kompetensi dipengaruhi secara signifikan oleh intervensi kegiatan. Selain itu, penerapan sistem feeder otomatis memberikan dampak operasional berupa peningkatan keteraturan pemberian pakan, pengurangan pemborosan pakan, serta efisiensi waktu dan tenaga kerja peternak. Tingginya tingkat keberterimaan teknologi tercermin dari konsistensi penggunaan sistem oleh sebagian besar peserta setelah kegiatan berakhir. Dengan demikian, kegiatan PkM ini membuktikan bahwa penerapan teknologi IoT yang tepat guna dan disertai pendampingan berkelanjutan mampu meningkatkan efisiensi budidaya ikan sekaligus mendorong kemandirian peternak secara berkelanjutan.

Abstract

The vegetative growth of melon (Cucumis melo L.) grown in hydroponic systems is influenced by proper nutrient management and the application of plant growth regulators. This study aimed to evaluate the effects of AB Mix nutrient concentration, gibberellic acid (GA₃), and their interaction on the vegetative growth of melon cultivated in a Dutch Bucket hydroponic system. The experiment was conducted at the CV. BestFarm Greenhouse, Deli Serdang Regency, North Sumatra, Indonesia, from December 2025 to March 2026 using a factorial Completely Randomized Design (CRD). The treatments consisted of three AB Mix concentrations (1800, 2200, and 2600 ppm) and four GA₃ concentrations (0, 40, 60, and 80 ppm). The results showed that AB Mix had a highly significant effect on several vegetative growth parameters, including plant height, number of leaves, leaf area, stem diameter, and vine length, with 2200 ppm producing the optimum vegetative growth. GA₃ application and its interaction with AB Mix had no significant effect on all observed vegetative growth parameters. These findings indicate that optimum AB Mix nutrition plays a more important role than GA₃ application in improving the vegetative growth of melon cultivated under a Dutch Bucket hydroponic system.
