The integration of Artificial Intelligence (AI) into precision agriculture has significantly improved plant disease recognition; however, many existing deep learning models remain computationally expensive and feature-redundant, limiting their deployment on low-power and edge devices. To address these limitations, this study proposes a lightweight framework for maize leaf disease recognition based on serial deep feature extraction, dimensionality reduction, and machine-learning–based classification. A pre-trained MobileNetV2 network is employed as a fixed feature extractor to obtain discriminative visual representations, while Principal Component Analysis (PCA) is applied to reduce feature dimensionality by approximately 76%, retaining 95% of the original variance and improving computational efficiency. The compressed features are subsequently classified using a Radial Basis Function Support Vector Machine (RBF-SVM), optimized via grid search and cross-validation. Experiments conducted on a four-class maize leaf disease dataset (Northern Leaf Blight, Common Rust, Gray Leaf Spot, and Healthy), with class imbalance handled during training, demonstrate that the proposed MobileNetV2–PCA–SVM pipeline achieves 97.58% accuracy, 96.60% precision, 96.59% recall, and 96.59% F1-score, outperforming the DenseNet201 + Bayesian-optimized SVM baseline (94.60%, 94.40%, 94.40%, and 94.40%, respectively). This improvement corresponds to a 2.98% accuracy gain, a 55% reduction in error rate, an 86% reduction in model parameters (20.31M to 2.75M), and an 85% reduction in model size (81 MB to 12 MB). These results indicate that the proposed framework provides a compact and efficient solution with strong potential for deployment in resource-constrained agricultural environments.

Abstrak:
Tomato crop yields face significant threats from plant diseases, with existing deep learning solutions often computationally prohibitive for resource-constrained agricultural settings; to address this gap, we propose Efficient Disease Attention Network (EDANet), a novel lightweight architecture combining depthwise separable convolutions with hybrid attention mechanisms for efficient Tomato disease recognition. Our approach integrates channel and spatial attention within hierarchical blocks to prioritize symptomatic regions while utilizing depthwise decomposition to reduce parameters to only 104,043 (multiple times smaller than MobileNet and EfficientNet). Evaluated on ten tomato disease classes from PlantVillage, EDANet achieves 97.32% accuracy and exceptional (~1.00) micro-AUC, with perfect recognition of Mosaic virus (100% F1-score) and robust performance on challenging cases like Early blight (93.2% F1) and Target Spot (93.6% F1). The architecture processes 128×128 RGB images in ~23ms on standard CPUs, enabling real-time field diagnostics without GPU dependencies. This work bridges laboratory AI and practical farm deployment by optimizing the accuracy-efficiency tradeoff, providing farmers with an accessible tool for early disease intervention in resource-limited environments.

Penelitian ini mengkaji dinamika akses dan kontestasi kepentingan aktor dalam perebutan lokasi pertambangan rakyat di Provinsi Jambi dan Bangka Belitung. Fokus kajian meliputi kondisi lapangan, faktor ekonomi yang mendorong partisipasi masyarakat, serta relasi kekuasaan antar aktor. Pendekatan kualitatif diterapkan dengan pengumpulan data melalui observasi, wawancara purposif, dan studi dokumentasi. Hasil menunjukkan pertambangan rakyat berkembang pesat karena tingginya potensi sumber daya alam dan kebutuhan ekonomi masyarakat, meskipun sebagian besar kegiatan masih berstatus ilegal. Ketidaksesuaian regulasi dan praktik perizinan menciptakan ketidakpastian hukum yang mengancam keberlanjutan aktivitas tersebut. Pertambangan rakyat menjadi sumber utama penghidupan dengan dampak positif pada pendapatan dan kualitas hidup, namun juga menimbulkan tantangan keberlanjutan, ketimpangan sosial-ekonomi, serta risiko lingkungan. Kontestasi kepentingan memperlihatkan konflik struktural antara masyarakat, elite politik, dan pemilik modal yang didorong oleh lemahnya tata kelola dan regulasi. Dominasi perusahaan besar dan keterlibatan aktor lokal dalam praktik rente memperkuat perebutan sumber daya sebagai arena kekuasaan. Studi lanjutan disarankan untuk mengkaji narasi dan wacana antar pemangku kepentingan guna memperdalam pemahaman pembentukan kebijakan pertambangan rakyat di tingkat lokal.This study examines the dynamics of access and the contestation of interests among actors in the struggle over artisanal mining locations in the Jambi and Bangka Belitung Provinces. The focus of the study includes field conditions, economic factors driving community participation, and power relations among actors. A qualitative approach is applied, with data collected through observation, purposive interviews, and document studies. The results show that artisanal mining is rapidly developing due to the high potential of natural resources and the economic needs of the community, although most activities remain illegal. Regulatory mismatches and licensing practices create legal uncertainty that threatens the sustainability of these activities. Artisanal mining serves as a primary livelihood source with positive impacts on income and quality of life, but it also poses challenges related to sustainability, socio-economic inequality, and environmental risks. The contestation of interests reveals structural conflicts between communities, political elites, and capital owners, driven by weak governance and regulation. The dominance of large companies and the involvement of local actors in rent-seeking practices strengthen the competition over resources as a power arena. Further studies are recommended to examine the narratives and discourses among stakeholders to deepen the understanding of artisanal mining policy formation at the local level.

This research aims to analyze the production factors that influence the production of cayenne pepper and see the level of efficiency in the use of production inputs in cayenne pepper farming in Bocek Village, Karangploso District, Malang Regency. The data analysis method used in this research to determine the effect of using production factors in cayenne pepper farming is Cobb Douglas model analysis. The research results show that cayenne pepper farming in Bocek Village uses production inputs simultaneously and influences the production of cayenne pepper. Partially, the use of land area input, NPK fertilizer and KCl fertilizer has an effect on cayenne pepper production in Bocek Village. Meanwhile, the variables of seeds, manure, pesticides and labor have no partial effect on cayenne pepper production in Bocek Village. Technically the use of each Input variable is inefficient. Allocatively, the use of input variables such as land area, seeds, manure, pesticides and labor has a value 1, meaning the use of production factors is inefficient. Meanwhile, NPK fertilizer and KCl fertilizer have a value of 1, meaning that the use of production factors is not allocatively efficient. Economically, the use of input variables such as land area, seeds, manure, pesticides and labor is inefficient and the variables NPK fertilizer and KCl fertilizer are not economically efficient.

This article explains the Bakaua ritual at sacred graves, a tradition of the Nagari Sungai Limau community that has deep theological value. This research aims to analyze the meaning of theological values in the Bakaua ritual and how its practice can strengthen people's spiritual relationships. Using a descriptive qualitative approach, this research examines the spiritual, social, and cultural aspects inherent in the Bakaua tradition. The research results indicate that this ritual serves not only as a means of prayer and respect for ancestors but also as a medium for strengthening social relations and preserving local wisdom. Apart from that, the Bakaua ritual is seen as a form of asking for protection, expressing gratitude, and fulfilling vows, which reflects the close relationship between culture and theology in the life of Minangkabau society. The method used in this research is qualitative, encouraging a different approach from previous research, which only discussed Bakaua dramaturgy in the Minangkabau society. However, this paper places more emphasis on aspects of theological values in the Bakaua ritual tradition at sacred graves. This study highlights how theological meaning is embodied through symbolic practices, offerings, and communal prayers that represent submission to divine will. It also reveals how the ritual facilitates intergenerational transmission of spiritual values, maintaining continuity of belief systems in modern contexts. By analyzing community participation and oral narratives, the research uncovers deep spiritual motives rooted in Islamic beliefs intertwined with local cultural expressions. In addition, the findings underscore the community’s resilience in preserving traditional theology-based rituals despite the influence of modernization and shifts in religious interpretations. The Bakaua ritual thus becomes a cultural-theological bridge that binds generations and sustains spiritual identity within the dynamic life of the Minangkabau people.
