Abstract

This study compares the performance of two deep learning architectures, Xception and MobileNet, for classifying skipjack and mackerel tuna, with a focus on accuracy and computational efficiency. MobileNet achieved an impressive accuracy of 97%, with precision, recall, and F1-score all at 97%, and demonstrated a faster prediction time of 0.06 seconds, making it well-suited for real-time applications. In contrast, Xception achieved an accuracy of 93%, with a precision of 94%, recall of 93%, and an F1-score of 93%. However, its prediction time was slower at 0.13 seconds, indicating a higher computational complexity. Although Xception delivered substantial accuracy, MobileNet outperformed it in terms of efficiency, suggesting that MobileNet is better suited for applications with limited resources or time constraints. The results indicated that MobileNet's lightweight architecture makes it ideal for mobile or embedded systems. At the same time, Xception's more complex structure may be advantageous for tasks that require higher precision in image processing. This research makes a significant contribution to the development of deep learning-based methods for fish species classification, offering improvements in both accuracy and speed.

Abstract

Word error correction is challenging due to the variety of errors. This research proposes a combination of two similarity algorithms to improve accuracy. The objective is to evaluate how each algorithm responds to different types of spelling errors and to assess the effectiveness of their combined performance. Jaro-Winkler determines initial similarity by assigning more weight to word prefixes, effectively addressing errors due to transposition and character omission. This algorithm excels in scenarios where the beginning of the word is critical to identifying the correct candidate. In contrast, Jaccard similarity filters candidates based on character set similarity, which helps assess the overall composition similarity of the word but does not consider character order. The test results show that Jaro-Winkler is more dominant in providing relevant correction candidates, with higher accuracy in the 1-best (68.94%) and 5-best (90.78%) scenarios compared to Jaccard (55.25% and 78.42%). This performance difference suggests that Jaro-Winkler is more suitable for the initial screening of candidates. The combination of the two algorithms proved to be more effective in handling different types of word errors than when used separately, resulting in a more robust overall correction mechanism.

Abstract

The Al-Fajar Mataram Foundation, an integrated Islamic school that has levels from Kindergarten, Elementary, and Middle School, is facing problems in the process of loading student uniform data, which is still done manually. This process often causes delays, uncertainty, errors, and a lack of transparency for schools and parents regarding the status of uniform production. To overcome this, it is proposed to develop a "Web-Based Uniform Manufacturing Process Monitoring System" using the Prototype method. This method was chosen because it allows users to directly see and test the system from the early stages of development. This provides an opportunity for users to provide suggestions and input directly, which can then be used by developers to improve system features that they feel are lacking, bringing them into line with what is needed. With this system, data regarding the uniform-making process can be managed more easily, making it easier to send data to tailors and allowing parents to monitor the status of their child's uniform-making directly. The results of testing using the Mean Opinion Score indicated a high level of user acceptance, with a User Acceptance Test score of 87.8%. This suggests that the system is highly beneficial for users.

Abstract

Libraries are essential tools for supporting education and learning activities. However, libraries in some areas still use manual systems to manage book data and other services. East Lombok Regency is one such area that requires an updated library information system to enhance the efficiency and effectiveness of its services. Observations at the East Lombok Regency Library and Archives Office revealed that library services are still conducted manually, with librarians using notebooks to record book borrowings. This manual system poses challenges in managing borrowed and returned books, especially as the East Lombok Library and Archives Office permit schools nationwide to borrow books. To address these issues, researchers employed the Rapid Application Development (RAD) method to design the information system. This method was chosen for its ability to shorten development time compared to traditional methods. The newly developed library information system aims to assist schools facing a shortage of books, particularly in remote village areas. The application of RAD successfully increased development efficiency and improved the system's effectiveness in meeting the library's operational needs. Furthermore, the system reduced dependence on manual processes, enhanced data accessibility, and simplified library data management. These improvements enable more optimal library services for the residents of East Lombok. This success is supported by the results of a questionnaire, with 80% of respondents agreeing that the system effectively meets their needs.

Abstract

The increasing need for quail farmers to identify diseases quickly and accurately, considering that many farmers do not have in-depth knowledge about the symptoms of diseases that may occur and the treatments that must be administered once the quails are infected. The lack of veterinarians also causes farmers to be anxious about handling diseases that affect quails. This research aims to develop an expert system that diagnoses quail diseases using the Naïve Bayes method. The methods applied in this study include collecting data on quail disease symptoms, processing data to transform categorical values into numerical ones, and implementing the Naive Bayes algorithm by dividing the dataset into training and testing data. The research results show that the developed model achieved an accuracy of 82.75% in diagnosing quail diseases. This accuracy is quite competitive compared to previous studies that used similar methods for other livestock with accuracy levels ranging from 60% to 90%. The system's performance evaluation using a confusion matrix and classification report indicates that the model can classify most cases correctly, although there are some prediction errors in certain classes. This shows that the effectiveness of the expert system in diagnosing quail diseases using the Naive Bayes method can provide a solution for farmers to recognize and address diseases earlier.
