Abstract

Dataset imbalance is a critical challenge in plant disease image classification because it causes bias towards the majority class. This study evaluates the effectiveness of augmentation-based oversampling techniques on the classification performance of citrus leaf images using the MobileNetV2 architecture. The four leaf disease classes classified include Greening, Fresh, Canker, and Blackspot. The dataset was obtained from a public repository and processed through preprocessing (resize, normalization) and augmentation (rotation, flipping, zoom) stages. The model was trained and tested in two scenarios: baseline (unbalanced data) and mitigation (data balanced through augmentation). The experimental results show that the mitigation approach was able to increase accuracy from 91.92% to 93.94%. The F1-score, precision, and recall values also increased significantly, especially in the minority class. Evaluation using a confusion matrix reinforced the finding that augmentation-based oversampling is effective in reducing classification errors. This study shows that the integration of augmentation techniques and MobileNetV2-based transfer learning can significantly improve classification performance and contribute to the development of early detection systems for plant diseases in precision agriculture.

Abstract

Penelitian ini bertujuan menganalisis efektivitas penerapan Business Intelligence (BI) dalam meningkatkan efisiensi pengelolaan stok pada Toko Buku Toha Putra Cirebon, yang masih menggunakan pencatatan manual dan sering mengalami ketidaktepatan informasi, overstock, dan stockout. Metode yang digunakan adalah pendekatan kuantitatif deskriptif dengan memanfaatkan data operasional penjualan, pembelian, dan persediaan yang kemudian diproses melalui tahapan ETL dan integrasi ke dalam data warehouse sebelum dianalisis menggunakan dashboard interaktif. Hasil penelitian menunjukkan bahwa penerapan BI meningkatkan nilai stock turnover dari 2,1 kali menjadi 3,4 kali, serta menurunkan days of inventory dari 62 hari menjadi 41 hari. Selain itu, tingkat stockout berkurang sebesar 18% setelah penerapan BI. Temuan ini menunjukkan bahwa BI mampu menyediakan informasi yang lebih akurat, mempercepat analisis, dan meningkatkan kualitas keputusan pemesanan. Secara keseluruhan, penelitian ini memberikan kontribusi praktis bagi ritel buku dalam optimalisasi persediaan dan kontribusi teoretis berupa model implementasi BI untuk usaha skala menengah.
