Abstract

Presipitasi merupakan komponen fundamental dalam siklus hidrologi Bumi yang memiliki dampak signifikan terhadap ekosistem, produktivitas pertanian, dan pengelolaan sumber daya air. Variabilitas presipitasi, terutama pola musiman, sangat penting untuk dipahami dalam konteks perencanaan yang efektif dan strategi adaptasi terhadap perubahan iklim yang semakin nyata. Penelitian ini bertujuan untuk mengeksplorasi variabilitas musiman curah hujan di Bangladesh melalui analisis deret waktu yang komprehensif, dengan memanfaatkan teknik statistik canggih, termasuk model Autoregressive Integrated Moving Average (ARIMA), Seasonal Autoregressive Integrated Moving Average (SARIMA), dan Exponential Smoothing State Space (ETS). Data yang digunakan dalam penelitian ini mencakup catatan curah hujan dan suhu rata-rata bulanan dari tahun 1901 hingga 2023, yang diambil dari Humanitarian Data Exchange (HDX). Analisis dilakukan untuk mengidentifikasi pola dan tren musiman yang ada dalam data tersebut. Hasil analisis menunjukkan bahwa model SARIMA (2, 0, 1) × (0, 1, 1, 12) memberikan kinerja terbaik dibandingkan dengan model lainnya, dengan nilai Root Mean Squared Error (RMSE) dan Mean Absolute Percentage Error (MAPE) yang rendah, yang menunjukkan akurasi prediksi yang tinggi. Sementara itu, model ETS juga menunjukkan hasil yang baik dalam hal akurasi, tetapi dengan nilai MAPE yang lebih tinggi, yang mengindikasikan bahwa meskipun model ini mampu menangkap pola musiman, proporsi kesalahan relatif terhadap data aktual lebih besar. Penelitian ini menekankan pentingnya mempertimbangkan komponen musiman dalam pemodelan deret waktu, karena fluktuasi musiman yang terjadi secara periodik dapat ditangkap dengan lebih baik, sehingga menghasilkan prediksi yang lebih konsisten dan akurat. Dengan demikian, hasil penelitian ini memberikan wawasan berharga untuk perencanaan dan strategi adaptasi di masa depan, terutama dalam konteks perubahan iklim yang dapat mempengaruhi pola curah hujan.

Abstract

In the era of modern agriculture, farmers face increasingly complex challenges related to controlling tomato plant diseases. Lack of knowledge and in-depth understanding of the types of diseases that may occur in tomato leaves can result in errors in identifying plant health problems, which can ultimately disrupt productivity and sustainability of crop yields. There is a major urgency that drives this research is the need for a better understanding of the diseases that affect tomato plants. In addition, the need to develop accurate models to detect diseases quickly and efficiently and the importance of implementing solutions that are practical and easily accessible to farmers. This study aims to provide farmers with useful tools to recognize and treat tomato leaf diseases more effectively so that they can increase yields and significantly increase their income. The model developed is expected to be able to identify and classify various types of tomato leaf diseases with high accuracy. This study utilizes a deep learning method using a Convolutional Neural Network (CNN) based on the EfficientNetV2L architecture in the tomato leaf disease classification process. This study produces an accuracy of 97.22% in the classification process using the EfficientNetV2L architecture and the implementation of a model that can be easily adopted by farmers. The developed model is integrated into a web-based system that can be accessed by farmers widely.

Abstract

Government agencies often encounter challenges in enhancing the efficiency and accuracy of financial report management, particularly in the cash reconciliation process. This study, conducted at the Regional Financial and Asset Management Agency (BPKAD) of Mempawah Regency, addresses the inefficiencies of traditional reconciliation methods that require face-to-face interactions and up to two working days to complete. The research aims to develop the Official Cash and Operational Expenditure Information System (SIKASBON) using the Agile methodology, enabling a more responsive, flexible, and user-oriented financial data synchronization process. The system was developed through a structured approach involving requirement analysis, design, development, testing, deployment, and review. System evaluation using the System Usability Scale (SUS) yielded an impressive average score of 85.2, categorized as A+ (Best Imaginable). The findings demonstrate that SIKASBON significantly improves transparency and efficiency in managing cash and operational expenditures. Most notably, the time required for reconciliation was reduced from two working days to just 10 minutes. This research contributes to the digital transformation of public financial management by offering a scalable solution that aligns with user needs and promotes accountability in government operations.

Abstract

The YOLOv8 accuracy curve highlights clear overfitting. As shown in the graph, the model reaches 100% training accuracy from the first epoch and remains flat, indicating it memorized the training data. However, validation accuracy lags behind, fluctuating between 90% and 92% without significant improvement. This discrepancy between training and validation performance suggests that YOLOv8 struggles to generalize to unseen data. The issue likely stems from its architecture, which is optimized for object detection tasks that prioritize object localization over feature extraction for classification. When repurposed for classification, YOLOv8 may not extract the nuanced visual patterns needed to differentiate similar classes, such as trucks and buses. Consequently, although YOLOv8 performs well on the training set, its classification accuracy in real-world scenarios is limited. Addressing this may require architectural adjustments, stronger regularization, or more diverse training data to enhance the model’s generalization for pure classification tasks.

Abstract

In the traditional learning methods where teachers relied on teaching aids like books, some students still struggled to understand the material being taught. This was particularly evident in lessons about human body organs. To create a learning process that is effective, efficient, and aligned with the advancements of modern technology, traditional methods alone are no longer sufficient. A more interactive and engaging learning model is crucial to foster enjoyable and accessible learning experiences. To address this, an Android-Based Multimedia Application for learning about human body organs was developed. This application aims to facilitate the teaching and learning process, especially for middle school students. Through the app, students can access various learning materials such as the respiratory system, digestive system, musculoskeletal system, excretory system, and circulatory system, complemented by images and animations. Additionally, the app includes practice exercises that help students assess their understanding of the material. By leveraging technology, particularly Android and multimedia, the learning process becomes more enjoyable and engaging. The combination of animations, sound, and text enhances the overall learning experience. Students can now access educational materials anytime and anywhere using their Android devices.
