Penelitian ini mengeksplorasi dan menganalisis teknik optimisasi kinerja memori dalam bahasa pemrograman Dart, khususnya dalam konteks aplikasi pemantauan karyawan. Mengingat pentingnya pengelolaan memori yang efisien dalam pengembangan aplikasi real-time, penelitian ini berfokus pada penggunaan keyword const untuk meningkatkan performa aplikasi. Hasil eksperimen menunjukkan bahwa penggunaan const menghasilkan waktu proses yang lebih cepat tanpa mengurangi penggunaan memori. Analisis lebih lanjut mengungkapkan bahwa const memungkinkan optimisasi pada waktu kompilasi yang meningkatkan kecepatan eksekusi dengan memastikan objek tidak dapat diubah setelah dibuat. Namun, const tidak mempengaruhi jumlah memori yang dialokasikan untuk objek, menunjukkan bahwa ukuran memori tetap sama terlepas dari penggunaannya. Penelitian ini memberikan wawasan penting tentang bagaimana const dapat digunakan untuk mengoptimalkan performa aplikasi Dart dalam hal kecepatan, meskipun tidak berdampak signifikan pada penggunaan memori. Temuan ini diharapkan dapat memberikan kontribusi signifikan dalam pengembangan aplikasi Dart yang lebih efisien dan responsif, serta memperkaya literatur akademik terkait optimisasi kinerja memori dalam bahasa pemrograman Dart.

Recent advancements in the field of information security have underscored the imperative to fine-tune Bcrypt parameters, particularly focusing on the optimal number of rounds as the objective of research. The method of research is a Brute Force Search method to find the optimal value of bcrypt rounds. The primary focal point of optimization lies in the number of Bcrypt rounds due to its direct impact on security levels. Elevating the number of rounds serves to fortify the security of the Bcrypt algorithm, rendering it more resilient against brute-force attacks. The execution of the Bcrypt rounds in the experimental method mirrors real-world scenarios, specifically in the evaluation of Bcrypt parameters with a focus on entropy assessment of the hash. The selection of the number of rounds should consider the specific needs of the system, where security takes precedence or faster performance is a crucial factor.

E-commerce technology enables efficient online transactions, providing customers with a convenient and efficient purchasing experience. In terms of production, e-commerce information systems can be integrated with production management, enabling monitoring of the production process, optimizing production efficiency and reducing the risk of stock shortages. E-commerce technology also opens up opportunities for more sophisticated marketing strategies, as MSMEs can utilize consumer data analysis, increasing customer appeal and ordering and sales. E-commerce technology facilitates direct interaction between consumers, fostering closer relationships and improving customer experience. The development of e-commerce technology has significantly increased the effectiveness and efficiency of MSMEs specifically in the fried chicken sector, enabling them to compete in the digital business era. The purpose of this study is to develop an E-Commerce information system in the "Maju Makmur" Kalasan fried chicken industry center that manages MSMEs fried chicken. The research method is a prototype model. This model starts from data collection, system design and testing. The stages of the prototyping development model consist of: communication, rapid planning, rapid modeling, construction, and delivery. The results of this study are a web-based system to optimize consumer, production, and marketing processes in order to increase operational efficiency and market access through an online platform.

The increase in the budget allocation for procurement of goods or services in the Agam Regency Government cannot be separated from the problem of procurement of goods or services. In Agam Regency, the problem that often arises in the appointment of commitment making officials is limited human resources in managing construction work so that many projects are found to be late in completing their work. The aim of the research is to identify factors and determine the most dominant factors that influence commitment making officials performance in construction projects in Agam Regency, and create a measurement model for the relationship between commitment making officials performance. The research method used is a quantitative research method, namely by distributing questionnaires to respondents. The results of the research conducted show factors that influence commitment making officials performance in construction projects in Agam Regency, namely the Technical Capability and Workload factors, the Capability factors in planning and control, the Knowledge and Budget Factors and the Skills Factors

Autoencoder-based models have shown strong potential for anomaly detection in complex time-series data; however, they often assume equal importance across latent dimensions, resulting in inefficiencies and reduced precision. This study addresses this limitation by introducing the Entropy-Based Bit Allocation Quantizer (EBAQ), a novel quantization framework that adaptively allocates bits to each latent dimension based on its entropy, preserving more precision where information content is highest. The primary objective is to enhance representational efficiency and anomaly detection performance without increasing model complexity or computational cost. EBAQ is implemented as a plug-and-play module within a standard autoencoder architecture, requiring no retraining or architectural modification. The method was evaluated using a publicly available ECG dataset, where reconstruction-based anomaly detection was employed to assess its performance. Results show that EBAQ outperforms the standard autoencoder baseline, achieving higher accuracy (94.9%), precision (99.4%), and recall (91.4%), while also demonstrating more apparent separation between normal and anomalous data in latent space visualizations. These findings confirm that entropy-aware quantization improves both fidelity and interpretability in unsupervised anomaly detection. Overall, this work presents a theoretically grounded and practically efficient solution that bridges information theory and deep learning, offering a human-centered approach to developing more intelligent and efficient AI systems for real-world applications.

The objective of this study is to evaluate the effectiveness of audiovisual and interactive media in improving the memorization of short surahs among early childhood students at PAUD Al-Fitrah Jaya Asri, Jayapura City, and to investigate its influence on children's motivation and memory retention. The study utilized a descriptive qualitative methodology, incorporating participants including the principal, Islamic Education teachers, and parents. Data were collected by direct observation, in-depth interviews, and documentation, while data analysis followed the Miles and Huberman paradigm, which included data reduction, data presentation, and conclusion development. The results show that using animated movies as audiovisual aids to help kids remember short surahs greatly improved their interest, focus, and ability to remember. Children were able to remember and recite the surahs more readily and with better pronunciation (makharijul huruf) than with traditional techniques of becoming used to them. Also, using this media made parents more involved in the muroja’ah (review) process at home, which helped connect what students learned at school with what they learned at home. Some children needed a lot of help, but audiovisual media turned out to be a beneficial and unique way to learn. This study finds that audiovisual media is a relevant and effective teaching approach for enhancing the memorization of short surahs in early childhood learners, provided there is suitable monitoring and careful planning to meet the developmental requirements of children.
