Abstract

The emissions of carbon dioxide (CO2) significantly contribute to the rise in global temperatures and the exacerbation of climate change. Various initiatives have been undertaken to reduce CO2 emissions, notably through the adoption of carbon capture technologies. These technologies include Carbon Capture and Utilization (CCU), Carbon Capture and Storage (CCS), and the integrated approach of Carbon Capture, Utilization, and Storage (CCUS). Our study aims to elucidate the operational principles of CCU, highlight the benefits of carbon capture, and provide recent updates on the application of CCU and CCS in daily contexts. Utilizing a qualitative descriptive methodology through a literature review, we examine the primary sources related to CCU and CCS from various databases such as Scopus, Springer, Taylor & Francis, and Google Scholar, covering the period from 2014 to 2024. As a novelty, our review covers physical techniques like absorption, gas or membrane separation, and pressure-temperature manipulation, alongside chemical methods such as the adsorption of amine compounds. Furthermore, biological techniques, including fixation, are also utilized. The operational framework of carbon capture technology is structured around three main processes: pre-combustion, post-combustion, and oxy-combustion. Notably, carbon capture technology incorporates the cultivation of microalgae as a fixation strategy, which promotes not only environmental sustainability but also shows significant promise for future applications. This method effectively sequesters large quantities of CO2 while requiring minimal nutritional resources. The advantages of utilizing microalgae include enhanced efficiency in CO2 fixation compared to terrestrial plants, reduced contamination, and a relatively simple operational structure. It is evident that the adoption of carbon capture technology is expected to increase in the coming years, particularly in light of the ongoing challenges posed by climate change. Prospective advancements in carbon capture technology are then discussed based on the review result. Thus, our literature review contributes to promoting the broader implementation of carbon capture technologies.

Abstract

Drop voltage is one of the main problems in the distribution system which has an impact on reducing the quality of voltage received by customers. This research aims to reduce voltage drop in the distribution system according to the standard voltage drop tolerance limit of 5% set in SPLN 72: 1987 on the CLDG extension by applying the Particle Swarm Optimization (PSO) optimization method in the development of express feeders. The CLDG feeder has a radial network topology with a channel length of 32.75 km with loads spread along the network. The simulation process was carried out to analyze the existing conditions and after optimization, using Backward Forward Sweep (BFS) power flow with the help of MATLAB R2023b software for its application and validated using ETAP 19.0.1. The results showed that PSO successfully determined the optimal location of express feeder development from bus B01 to bus B18, with the placement of a new LBS at bus B17. This development reduced the number of critical buses from 52 to 16 buses, and the maximum voltage drop from 9.86% to 6.67%.

Abstract

Meningkatnya penggunaan beban nonlinier menyebabkan masalah harmonisa yang menurunkan kualitas daya listrik. Penelitian ini menganalisis implementasi filter daya aktif tiga fasa empat kawat dengan kendali Model Predictive Control (MPC) untuk mereduksi harmonisa, berfokus pada pengaruh time sampling terhadap perilaku switching kontroler dalam alur model-based design. Pengaru ini diamati menggunakan Model Based Design dan diamati melalui metodologi yang meliputi perancangan dan pengujian melalui tahapan Model in the Loop (MIL), Software in the Loop (SIL), dan Processor in the Loop (PIL) menggunakan FPGA Zedboard. Kinerja dievaluasi berdasarkan perbandingan  Total Harmonic Distortion (THD) arus dan faktor daya. antara MIL dengan SIL, kemudian MIL dengan PIL. Hasil MIL menunjukkan kendali MPC dengan time sampling ideal 10 nanodetik berhasil menurunkan THD sumber (<5% pada beban seimbang) dan memperbaiki faktor daya. Namun, pada SIL dan PIL, kinerja menurun drastis. Perilaku switching pada SIL tidak efektif akibat disparitas time sampling 10 milidetik pada kontroler SIL dibandingkan dengan 10 nanodetik pada plant). Pada PIL, THD melonjak (~44%-~54%) disebabkan potensi masalah timing constraints FPGA dan sisa isu time sampling, yang menggagalkan perilaku switching efektif.
