Abstract

University requires the integration of data from one system with other systems as needed. This is because there are still many processes to input the same data but with different information systems. The application of data integration generally has several obstacles, one of which is due to the diversity of databases used by each information system. Schema matching is one method that can be used to overcome data integration problems caused by database diversity. The schema matching method used in this research is linguistic and constraint. The results of the matching scheme are used as material for optimizing data integration at the database level. The optimization process shows a change in the number of tables and attributes in the database that is a decrease in the number of tables by 13 tables and 492 attributes. The changes were caused by some tables and attributes were omitted and normalized. This research shows that after optimization, data integration becomes better because the data was connected and used by other systems has increased by 46.67% from the previous amount. This causes the same data entry on different systems can be reduced and also data inconsistencies caused by duplication of data on different systems can be minimized.

Abstract

Patient data is one of the datasets managed by the hospital. Patient data in the form of examination results and other data is important data that is private and confidential. Therefore, patient data needs to be secured so that there is no misuse of data by parties who are not responsible for things that can harm the data owner. One of the several methods that can be used to secure data is cryptography. Cryptography itself has several algorithms, one of which is blowfish. This study applies the blowfish algorithm to secure patient data in the database to reduce the possibility of data misuse by irresponsible parties. This study succeeded in implementing the blowfish algorithm for securing patient data. The data stored in the database is the result of encryption using the blowfish algorithm, the results of which are difficult to understand because there is a combination of symbols and text. The application of the algorithm affects the data storage time in the database, which originally took 0.12 seconds to save data and now takes 0.28 seconds to store data.

Abstract

Timely and accurate prediction of cocoa fruit ripeness is critical for optimizing harvest schedules, improving yield quality, and supporting post-harvest processing. Conventional visual inspection methods are prone to subjectivity and inconsistencies, especially when distinguishing among multiple ripeness levels based on fruit age. This study proposes a deep learning approach that leverages multi-model convolutional neural network transfer learning combined with image data augmentation to classify cocoa fruit into four maturity stages derived from fruit age. An augmented dataset of cocoa fruit images was used to fine-tune five well-established pre-trained models: MobileNetV2, Xception, ResNet50, DenseNet121, and DenseNet169. Data augmentation techniques were employed to increase variability and improve model generalization. Model evaluation was conducted using a standard 80:20 training-to-testing split to ensure sufficient data for learning while preserving a representative test set across all ripeness classes. The results demonstrate that DenseNet169 consistently outperformed other models, achieving the highest average accuracy of 85,05%, followed by DenseNet121 84,06%. Across all models, the use of data augmentation led to notable performance gains, highlighting its importance in enhancing predictive capability and reducing overfitting. The proposed framework shows promising potential for automating ripeness classification in agricultural contexts, offering a robust, scalable, and accurate solution for intelligent cocoa harvest management. This work contributes to the growing application of deep learning in precision agriculture, particularly in addressing fine-grained classification problems using limited but enriched visual data.

Abstract

Maternal mortality remains a critical public health issue that can be reduced through effective early detection of high-risk pregnancies. In Indonesia, the Poedji Rochjati Score Card (KSPR) is widely used as a screening tool; however, its implementation is predominantly manual, leading to inefficiencies in data management, risk classification, and continuity of antenatal care. This study aims to develop a web-based Poedji Rochjati Score to support early detection of high-risk pregnancies at the primary healthcare level. This research employed an applied research and development design using the Rapid Application Development (RAD) method. The results indicate that the developed system successfully automates KSPR scoring and pregnancy risk classification based on standardized criteria. The system improves the accuracy and consistency of risk assessment, enhances maternal health data management, and supports longitudinal monitoring of pregnancy risk status. Implementation findings show that the system facilitates more efficient antenatal care services and provides structured risk reports to support clinical and referral decision-making. This study contributes to applied health informatics by demonstrating how standardized maternal risk screening can be effectively digitalized at the primary healthcare level. In conclusion, the web-based Poedji Rochjati Score information system offers an effective and innovative solution for strengthening early detection of high-risk pregnancies. The integration of a standardized screening tool with digital technology enhances screening accuracy, service efficiency, and data continuity in antenatal care. This study provides a practical foundation for further development and wider implementation of digital maternal health screening systems to support improved maternal healthcare quality.
