Abstract

Electrocoagulation is a method that is often used to improve the quality of solutions. The electrocoagulation method has the advantages of not using chemical additives, easy and inexpensive operation, and having high efficiency in removing pollutants and contaminants. In this method, the pollutants obtained are easy to separate because of the floating surface of coagulated sediments called flocs. The solution used is FeCl3.6H2O solution as a source of iron content and a replacement medium for water or solutions containing iron. The iron content in water is more dominant than other heavy metals, whereas in excess it can cause health problems. In this study, a standard iron solution was used at 10 ppm variations using the electrocoagulation method using an aluminum plate at a voltage of 25 volts and a time of 60 minutes, and testing for pH, TDS, and UV-Vis was carried out. Obtained after the electrocoagulation process of the Fe standard solution, each concentration experienced an increase in quality, in the form of a significant decrease in Fe concentration (ppm), an increase in the pH value from 3 to 5, and a decrease in the TDS value of 80.69% -85.88%. So, the electrocoagulation method can be applied to improve the quality of a solution.

Abstract

The Bumang Watershed is a stream of water originating from the Bumang Reservoir in Kemuja Village, Bangka Regency to hold back water from flooding the surrounding rice fields. Since the Bumang watershed embankment was built, the embankment has been damaged in the upper part of the Bumang watershed. The main cause is underground erosion. The erosion caused the embankment foundation to become weak, which was identified as a weak zone. The method used to identify weak zones in the embankment is the Wenner configuration resistivity geoelectric method. The Wenner configuration has good sensitivity to lateral changes compared to other configurations. Field data acquisition consisted of four passes with different electrode lengths and spacings. Based on the 2D cross-section of the subsurface of the Bumang watershed embankment, the weak zone is located on tracks 1, 2, and 3. On track 1 it is at a depth of 2.50 m - 3.19 m and 1.30 m - 3.19 m; on track 2 it is at a depth of 0 m - 2 m; and on track 3 it is at a depth of 0 m - 7 m, 2 m - 4.50 m, and 0 m - 4 m respectively.

Abstract

This systematic review examines recent developments in spray-coated solar cells through analysis of 127 peer-reviewed studies (2019-2024). Our findings highlight significant advances in ultrasonic spray techniques, achieving thickness variations of ±2.5% and perovskite-based device efficiencies reaching 21.7%. Large-scale implementation demonstrated successful coating areas of 1.5 m² while maintaining 90% of lab-scale performance. Despite promising results, stability remains challenging, with typical efficiency losses of 15-20% over 1000 hours. Current trends suggest commercial viability within 3-5 years, contingent upon advances in materials and processing techniques.
