Abstract

As one of unique non-volcanic geothermal field in Indonesia, mapping the groundwater flow in Nyelanding Village, South Bangka is essential as preliminary study for further exploration activity if the geothermal manifestation. In order to achieve this goal, we conduct a research using natural electrical properties of subsurface, Self-Potentials (SP) method. In this study, fixed-based technique was used where the spacing between measurement stations is the multiplication of 10 m along three lines at the study area. Raw field data (potential value) was corrected to diurnal and closure corrections. Further, SP anomaly was plotted and combined with topography data to be analyzed. The result shows potential value raging from -25mV to 100mV which in agreement with the lowest and highest elevation in topography map, respectively. This means, these values are controlled by topographic feature in the study area. Thus, in conclusion, the groundwater flows from the West to North East and South East part of the study area

Abstract

Padang Mulya Village, Koba District is part of the Koba Groundwater Basin area. This area has the potential of abundant aquifer layers. An aquifer is a layer of rock that can store water in large quantities. However, the continued increase in exploration of the aquifer layer will result in damage to the aquifer environment. In this case it is necessary to identify the aquifer layers to determine the depth and lithology of the constituent rocks. The resistivity geoelectric method of the dipole-dipole configuration is the most sensitive geophysical method for identifying aquifer layers. Measurements were made on six tracks to obtain data variations on current strength and potential difference. From these data variations in apparent resistivity values will be obtained. 2D modeling of the apparent resistivity value using the backward modeling method is carried out on each track in order to obtain a 2D cross-section of the subsurface structure. The 2D section of each track has an aquifer layer with a depth of 0 meters to 20 meters and is composed of clay, loamy sand, rather dense gravel sand and sandstone.

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

Kemuja Village Reservoir is one of the reservoirs located in Kemuja Village, West Mendo District, Bangka Regency, which was built in 2015. On the sides of the Kemuja Village Reservoir, there are embankments that are used to prevent flooding of rice fields. Based on the initial survey, the height of the embankment from the ground is ±2.6 m and the water level is ±1 m above the surface. This study aims to identify the stability of the Kemuja Village reservoir embankment based on 2D modeling using the Wenner configuration resistivity geoelectric method with a spacing of 8 m between electrodes. Based on 2D modeling, the Kemuja Village reservoir embankment has good stability on all tracks, except on track 1 at a depth of 0 m - 1 m with a measurement distance of 10 m - 14 m, track 2 at a depth of 0 m - 1 m with a measurement distance of 36 m - 40 m, track 3 at a depth of 0.5 m - 2 m with a measurement distance of 6 m - 8 m; 0 m - 1.5 m with a measurement distance of 12 m - 16 m and 0 m - 2 m with a measurement distance of 28 m - 30 m, traverse 4 at a depth of 0 m - 1 m with a measurement distance of 8 m - 10 m and 0 m - 2 m with a measurement distance of 44 m - 48 m.

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.
