Estimasi Sudut Kedatangan yang Ditingkatkan dengan CNN pada Array Antena MIMO Menggunakan Data Sinyal IoT Dunia Nyata

Abdul Karim — 2026-04-20

− This study proposes the application of a Convolutional Neural Network (CNN)–based approach to analyze signals in Internet of Things (IoT)–based MIMO antenna systems, with the aim of enhancing the understanding of system performance characteristics, particularly in predicting latency parameters. The CNN model is trained using real-world IoT signal data that have undergone comprehensive preprocessing stages, including data normalization, missing value handling, and feature engineering to ensure compatibility with the model input format. Experimental results on previously unseen test data demonstrate that the proposed model achieves a test loss of 1.4410, represented by the Mean Squared Error (MSE), and a Mean Absolute Error (MAE) of 0.9395. These results indicate that the model attains a relatively low prediction error and effectively captures the nonlinear relationships between signal features and system responses.

Visualization of the testing results reveals a strong correlation between actual and predicted latency values, although some dispersion remains due to channel complexity and the inherent variability of IoT signals. The distribution of prediction errors is centered around zero, indicating the absence of significant systematic bias in the model. Overall, the findings confirm the potential of CNN as a reliable approach for modeling and performance analysis of IoT-based MIMO antenna systems, while also highlighting opportunities for further development in spatial parameter estimation and intelligent wireless communication system optimization.

This study aims to analyze the effectiveness of a data-based system in the areas of sales and inventory provision at Master Stokist Takalar of PT Mega Gloryoung International (MGI). The study employed a mixed-method approach by integrating qualitative and quantitative data. Primary data were obtained through interviews, observations, and questionnaires administered to 20 respondents, while secondary data were collected from sales reports, transaction records, and inventory data. Quantitative analysis was conducted using descriptive statistics through effectiveness percentages and efficiency comparisons, whereas qualitative analysis was carried out through data reduction, data display, and conclusion drawing. The findings indicate that the data-based system is effective in the sales aspect, as reflected by an average effectiveness rate of 89%, reduced time required for transaction recording, data retrieval, and report preparation, as well as a 12% upward trend in sales. However, in the inventory provision aspect, the system’s effectiveness has not yet been optimal because stock management is still conducted manually, stock monitoring is not yet real-time, and demand forecasting remains reactive. These conditions indicate that the effectiveness of the system at Master Stokist Takalar is still partial, being strong in sales transactions but weak in inventory control. Therefore, stronger integration between the sales system and the inventory system is necessary to enhance distribution stability and reduce the risk of stockouts

Analisa Perbandingan Algoritma Shannon Fano Dan Algoritma Stout Code Pada Kompresi File Teks

Dito Putro Utomo — 2026-05-05

The rapid development of technology today attracts a lot of attention from the wider community. The dynamic development of computers is accompanied by the ability to get information very quickly. Data compression is a technique to reduce the amount of data in the original data. Data compression is usually applied to computer machines. This happens because each symbol displayed on the computer has a different bit value. The large size of text files will be a problem for storage space. Because the need for text files is very important, we tend to collect data in the form of text files, and often without realizing it, we store it in large sizes. This causes the need for storage media to be large. To overcome this problem, text files that have a larger size are used by compressing text files. Large data will be compressed into a small size, which will reduce storage. After applying the comparison of the Shannon Fano Algorithm and the Stout Code algorithm, compressing the text file has proven that the text file has been successfully compressed. After performing the text file compression process, the author can conclude that the Shannon Fano algorithm is better at performing the compression process.
