Visible Light Communication (VLC) is a communication system that uses visible light as its transmission medium to transmit information signals with Light Emitting Diode (LED) and LASER light sources using visible light between 400 THz (375 nm) to 800 THz (780 nm). VLC has several advantages over the use of radio frequencies in a system. Performance analysis is needed to prove these advantages. Performance analysis was carried out using a mathematical computational simulation using google colab with the python programming language. By taking into account the power allocation (?) strategy in the form of gain ratio power allocation (GRPA) and static power allocation (SPA). The interesting thing from this research is that the power allocation in the VLC system greatly influences the resulting performance. So, it can be locked that the SPA power allocation strategy can be adjusted by producing ?? = 1 and finding the optimal BER value in the range of 10-6 to 10^-3.

Dynamic economic dispatch (DED) is a crucial task in modern power systems, requiring efficient optimization to minimize generation costs while satisfying operational constraints. This study introduces a Hybrid Electromagnetic Field Optimization with Sine-Cosine Algorithm (EMFO-SCA) tailored to address the unique challenges of the Sulselbar 150 kV power system. Specifically, the algorithm is designed to handle non-linear cost functions, complex constraints, and dynamic load variations across a 24-hour scheduling period. EMFO-SCA achieves a balanced integration of global exploration (via Electromagnetic Field Optimization) and local exploitation (via the Sine-Cosine Algorithm), resulting in robust optimization performance. Applied to a system with seven active generator buses, EMFO-SCA demonstrates an average operational cost reduction of 0.27% compared to the Kho-Kho Algorithm (KKA). This improvement translates to measurable cost savings while maintaining strict adherence to generation limits, ramp rate constraints, and power balance at all intervals. For instance, during peak demand at 521.52 MW (hour 12), the method effectively minimizes costs without compromising operational reliability. The dual-phase design of EMFO-SCA enables faster convergence and higher accuracy than conventional methods, making it a scalable solution for real-world DED challenges. By optimizing power generation schedules dynamically and reliably, this study establishes EMFO-SCA as a significant advancement in energy system optimization, with clear potential for practical deployment in similar power systems.

Wireless communication technology continues to face challenges in meeting high bandwidth demands and the capability to serve numerous users. One promising solution is the non-orthogonal multiple access (NOMA) scheme, particularly through the use of power domain (PD) in the application of visible light communication (VLC) technology. However, PD-NOMA still faces power allocation and detection issues at the receiver end. We propose the Cognitive-SIC-VLC method, which considers the line of sight (LOS). Using combined multiplexing techniques, variations in user positions within the system can result in low SNR (dB) values when detecting a BER threshold of 10-3. In three power allocation experiment scenarios, the third scenario was the best with an initial power allocation of 0.95 and a power increment for each user of 0.05. This has been proven to have very low SNR requirements for users close to the LED.

Indonesia, as the largest archipelagic country in the world, also has several outer islands. Sebatik Island is one of the 92 outer small islands of Indonesia, located in a strategic position as it borders Malaysia. Various needs of society, one of which is electricity, are very important for people's lives and economic development. Thus, the goal is for all households in Indonesia to have access to electricity by 2024, with both the electrification rate and the ratio of electrified villages reaching 100%. An electricity plan is also necessary to help ensure that electricity is distributed fairly and equitably throughout Indonesia. Load prediction is an essential aspect of the load side of the electric power system that requires careful planning. Machine learning methods are not suitable for application in load prediction analysis in remote areas of small islands, which have limited space. Therefore, this research presents an alternative approach, specifically the spatial method utilizing (RTRW) documents. The application of this spatial method is intended to offer an overview of electricity load predictions that are more aligned with the actual situation. This spatial method analyzes the area size with land use development patterns according to local policies, multiplied by the standard definition of an activity in each spatial unit. Thus, an estimate of the peak load for each year is obtained, even up to ultimate conditions. The load prediction model follows the Gompertz equation, where the ultimate condition obtained is 63.55 MW, which may occur 118 years from the starting point in 2022. Choosing a 90% confidence level in the Monte Carlo simulation provides a reasonable range of predicted values. Based on this new knowledge, a country's electric utility will be able to build infrastructure and generate electricity in a more efficient manner.
