Abstract

In recent years, the response to climate change and the need for sustainable energy have driven the global energy transition towards renewable energy, particularly Solar Power Plants (SPP). As a tropical archipelagic country with abundant solar energy potential, Indonesia is increasingly committed to integrating renewable energy into the national electricity system. However, integrating SPP also has several drawbacks to the electrical system. For instance, there is an absence of inertia in SPP because the SPP does not contain rotating machines, and the intermittency is due to SPP power production being highly dependent on the availability of sun irradiance. This research analyzes the effects of SPP penetration on the existing electrical system. Newton Raphson load flow, three-phase line-to-ground short circuit, and transient disturbance are used to investigate the impact of SPP penetration. The results show that the SPP penetration enhances the voltage steady state profile due to the additional active power from SPP. Furthermore, there are no increasing short circuits due to the characteristic of an inverter with no impedance. In addition, the transient response has an effect as SPP has no inertia. Hence, the system tends to experience swings in conditions.

Abstract

Water pollution caused by dye effluents has become a global problem, for example in the textile, paper, and food industries. One common type of dye waste is bromophenol blue, which is considered to pose a low level of danger, but frequent exposure to its waste can cause skin irritation. This research was conducted using silver nanoparticles synthesized with purple sweet potato peels, which are rich in anthocyanin content so that it can be used as an active reducing agent and produce an adsorbent used for dye waste removal. Combination of biogenic-chemical method was chosen due to its simplicity, cost-effectiveness, and lower toxicity. Characterization of the obtained nanomaterials included UV-Vis spectroscopy, FTIR, SEM-EDX, and XRD. The results showed that the average crystal size of pure IBpe and the three IBpe-AgNPs were 7.09 nm, 8.68 nm, and 13.99 nm with an FCC crystal shape. The average particle sizes of the three IBpe-AgNPs were 82.76 nm, 85.72 nm, and 99.78 nm, with an almost spherical shape. The research found that IBpe-AgNP 1:9 demonstrated the highest adsorption efficiency of 77.24% compared to the other samples. In terms of desorption efficiency, the IBpe-AgNP 1:3 sample showed the highest value at 27.54% compared to the other three samples. Furthermore, the reuse test revealed that the IBpe-AgNP 1:9 sample had the highest reuse value at 27.02% compared to the other samples, showing the same trend as the first adsorption.

Abstract

Ethanol detection is critical in the beverage industry, where it is essential to monitor alcohol concentrations for quality control and compliance with regulatory standards. Traditional analytical methods, such as gas chromatography and distillation, offer accuracy but are often labor-intensive, time-consuming, and require sophisticated equipment. In contrast, electrochemical sensors and biosensors have emerged as promising alternatives due to their rapid response, portability, cost-effectiveness, and potential for real-time monitoring. Electrochemical sensors, particularly those enhanced with metal nanoparticles like platinum, palladium, or gold, have shown significant improvements in sensitivity, selectivity, and response time. These sensors offer the advantage of miniaturization, making them ideal for on-site analysis, although issues such as electrode stability, susceptibility to interference, and long-term reliability remain. On the other hand, biosensors, which leverage biorecognition elements like alcohol dehydrogenase (ADH) or alcohol oxidase, provide high specificity for ethanol, reducing interference from other compounds commonly found in beverage samples. Recent advancements in biosensor technology have focused on improving sensor stability, enzyme immobilization techniques, and reducing production costs. While biosensors offer high selectivity and sensitivity, they may still face challenges related to enzyme denaturation and environmental factors such as temperature and pH fluctuations. Both electrochemical sensors and biosensors are continuously evolving, with recent developments including the use of nanomaterials and novel biorecognition elements to enhance performance. This review will explore recent advances in electrochemical sensors and biosensors for ethanol detection in beverage samples, highlighting their potential, challenges, and future directions in this field.
