Abstract

An efficient and reliable electric power system must be able to maintain operational stability, especially in maintaining frequency stability to remain at its nominal value, both in constant conditions and when disturbances occur. For this reason, optimal frequency control is needed through Automatic Generation Control (AGC). In AGC, a controller is needed to accelerate the frequency response so that it is quickly stabilized. This study proposes the development of a 2DOF-PID controller into a 2DOF-PID-PIID optimized using the Dandelion Optimizer (DO) to improve AGC performance in the context of Load Frequency Control (LFC). The test results show that the DO algorithm gives better results compared to the Sine Cosine Algorithm (SCA), Pelican Optimization Algorithm (POA), and Archimedes Optimization Algorithm (AOA). Therefore, DO is chosen to optimize 2DOF-PID-PIID. The 2DOF-PID-PIID controller optimized with DO produces an ITAE (Integral Time Absolute Error) value of 0.001276, which is superior compared to the 2DOF-PID (0.00158), 2DOF-PID-PID (0.00158), PID (0.001833), and PIDD (0.002022) controllers, indicating its effectiveness in accelerating the response and maintaining frequency stability in the electric power system.

Abstract

This community service activity aims to strengthen Posyandu services in Desa Gondang through the application of early anemia detection technology. Limited access to health examinations has caused anemia to be underdiagnosed in rural communities, especially among pregnant women and vulnerable groups. The implementation method involved technology transfer, participatory assistance for Posyandu cadres, and direct health service activities involving the community. Approximately 137 participants consisting of pregnant women, elderly individuals, and productive-age community members were involved. The results show that Posyandu cadres were able to independently conduct early anemia screening, while the community gained easier access to health examinations and increased health awareness. The activity concludes that the application of appropriate health technology at the community level is effective in improving service quality and supporting sustainable community-based health services.
