Accurate fertile-infertile egg classification is crucial to improve hatching productivity and sorting efficiency. This study proposes MobileFusionV3, a MobileNetV3 architecture enriched with CBAM (Convolutional Block Attention Module) and Hybrid Texture Fusion (LBP and GLCM) to combine deep and texture features to be more robust to candling illumination variations. A dataset of 1,275 candling images (675 fertile, 600 infertile) was subjected to preprocessing (resizing, normalization, background enhancement) and realistic data augmentation (rotation, brightness/contrast changes, Gaussian noise, illumination variations). The model was trained using transfer learning, early stopping, and an evaluation scheme based on accuracy, precision, recall, F1-score, and AUC. The test results showed an accuracy of 97.2%, precision of 96.8%, recall of 97.5%, F1 of 97.1%, and AUC of 0.99, surpassing previous designs that did not use attention mechanisms and texture fusion. Grad-CAM++ analysis confirms the model's focus on physiologically relevant regions (embryonic shadow and air-cell), thus improving the reliability of interpretation. These findings indicate that lightweight, efficient designs based on attention and texture fusion have the potential to be implemented in smart hatchery systems and edge/mobile devices while maintaining high accuracy.

Penentuan tingkat kesejahteraan masyarakat memiliki peran penting dalam proses penyaluran bantuan sosial di tingkat desa. Namun, pendataan berbasis observasi manual masih menghadirkan potensi bias subjektif dan ketidakkonsistenan dalam pengambilan keputusan. Penelitian ini bertujuan mengembangkan model klasifikasi tingkat kesejahteraan masyarakat Desa Cikuya menggunakan algoritma Naïve Bayes sebagai pendekatan berbasis data yang lebih objektif. Tahapan penelitian meliputi pengumpulan data sosial ekonomi, pra-pemrosesan, encoding variabel kategorik, normalisasi variabel numerik, pelatihan model Gaussian Naïve Bayes, serta evaluasi menggunakan metrik akurasi, precision, recall, dan f1-score. Hasil penelitian menunjukkan bahwa model menghasilkan akurasi sebesar 98,33%, yang menunjukkan performa klasifikasi yang sangat baik. Analisis lebih lanjut mengindikasikan bahwa variabel pendapatan dan kondisi fisik rumah memiliki peranan paling dominan dalam membedakan kategori kesejahteraan. Model yang dikembangkan tidak hanya berfungsi sebagai alat klasifikasi, tetapi juga dapat dimanfaatkan sebagai sistem pendukung keputusan bagi pemerintah desa untuk menilai status kesejahteraan masyarakat secara lebih cepat, konsisten, dan bebas bias subjektif. Penelitian ini memberikan kontribusi pada pemanfaatan teknologi pembelajaran mesin dalam pemetaan kesejahteraan masyarakat, meskipun masih memiliki keterbatasan pada jumlah variabel dan cakupan data lokal.

Stunting remains a major health issue in Indonesia, especially among toddlers. This study aims to classify the nutritional status of toddlers (stunted and non-stunted) using anthropometric data from the Kaggle public dataset with the Support Vector Machine (SVM) algorithm. This dataset includes data on the height, weight, age, and gender of toddlers. It should be emphasized that the data does not originate from the Ciherang Bandung Posyandu, but rather the Posyandu is used only as a context for the potential application of the developed model. The process includes data acquisition, preprocessing (including normalization and data balancing using SMOTE), SVM model training, and evaluation with accuracy, precision, recall, F1-score, and ROC-AUC. The model was trained with an 70:30 data split and optimal parameters (C=1.0, gamma=0.01, kernel=RBF). The results showed high performance, indicating that this model can support early detection of stunting and the implementation of decision support systems in public health services.

It must be able to stand alone since abstracts are frequently given apart The utilization of information technology has developed into a vital instrument in enhancing operational efficiency and business competitiveness, particularly in the medium-scale retail sector. Accurate inventory management is the primary foundation for business sustainability to maintain consistent customer satisfaction. However, John Store currently faces complex operational obstacles as it relies entirely on manual recording methods. The absence of a structured internal database system causes significant data synchronization issues between administrative records and physical stock in the warehouse, thereby increasing the risk of sudden stockouts. The most fundamental and crucial issue lies in managing bundling category products, where a single package transaction often fails to accurately deduct the stock balance of individual components due to the high risk of human error in manual calculation. To address this inefficiency, this research aims to build the web-based John Store Information System (SIJOHNS) as an integrated internal back-office solution. System development applies the Waterfall method systematically, covering requirements analysis, system design through Flowmap, Data Flow Diagram (DFD), and Entity Relationship Diagram (ERD), to implementation using PHP programming language and MySQL database. Key system features include the automation of bundling stock mapping and multi-role access rights management. Based on Black Box Testing, the system is proven valid. The implementation of SIJOHNS successfully transforms inventory management into a digital format, ensures the accuracy of stock deduction in real-time, and presents analytical data visualization on the dashboard to facilitate the store owner in monitoring sales trends for more strategic and targeted business decision-making
