Evaluating the Results According to Simulations to Improve Power Control and Enhance Optical Communication Performance
In this paper, an experimental study has been conducted to detail power-control optimization in wavelength-division multiplexed (WDM) optical communication systems by use of Erbium-Doped Fiber Amplifiers (EDFAs). Our study shows that adaptive power control can greatly improve the performance of the system with a superb 35.7% improvement of the maximum power capacity relative to traditional constant power schemes. Throughout its study, the paper uses elaborate simulations to determine the bit-err...

Review Model of Decision Support System (DSS) Methods in The Contextual of Multimedia Platform Selection
Journal of Multimedia Trend and Technology
Vol 5
, No 1
(2026)
Selecting the right management multimedia application is a crucial strategic decision for organizations to optimize operations and minimize implementation risks. However, the vast array of application alternatives with diverse evaluation criteria often creates complexity in the decision-making process. This study aims to map the trends in Decision Support System (DSS) methods and identify the key criteria influencing management application selection through a Systematic Literature Review (SLR) a...

Development of contextual learning-based mathematics teaching modules on rational number materials
This research aims to develop a mathematics teaching module on rational number material for grade VII junior high school students that is valid, practical, and effective. This research is motivated by students' limited understanding of rational numbers and by the limitations of teaching materials that fail to connect the material to real-life contexts systematically. The research gap lies in the limited development of contextual modules that not only focus on validity and practicality but also c...

Students' errors in solving ethnomathematics word problems using the newman procedure: A perspective from learning styles
Some students had difficulty solving ethnomathematics word problems, indicating the need for further research to address this issue. This study aims to identify the types of errors made and the factors causing them. It applies Newman's Error Analysis, which includes reading errors, comprehension errors, transformation errors, process skill errors, and writing errors in the final answer. It incorporates the role of ethnomathematics as an innovation in contextual learning that introduces Indonesia...

Fractional Corner Charges in Ionic Crystals: A Case Study of Sodium Chloride Using the DV-Xα Molecular Orbital Method
Recent theoretical predictions have revealed that even simple ionic crystals such as sodium chloride (NaCl) can exhibit fractional corner charges due to their topological characteristics. In this study, we employ the DV-Xα molecular orbital method to analyze the electronic structure of NaCl clusters in 1D, 2D, and 3D configurations. Cluster models were constructed with varying atomic numbers, and their highest occupied molecular orbitals (HOMOs), net atomic charges, and electrostatic potential m...

Student learning motivation is a dynamic construct that changes over time in response to support, academic pressure, and fatigue. However, many existing studies examine motivation only at a single point in time or rely on descriptive approaches, limiting their ability to quantify how motivation evolves. This study develops a nonlinear mathematical model of student motivation dynamics and links the model to an empirical calibration framework. The proposed model represents motivation as a bounded...

Cooperatives, as a pillar of the people’s economy, play a strategic role in improving community welfare. However, in practice, cooperatives still face various challenges, particularly in terms of digitalisation and the limited capacity of human resources (HR). This community service activity aims to enhance digital literacy and HR capacity through assistance in implementing a digital-based financial system at Koperasi Merah Putih in Karanganyar Gunung, Semarang City. The method employed is a par...
