Abstract

The skin, the body's largest organ, plays a key role in protection, temperature regulation, sensation, sweat excretion, and vitamin D synthesis. It also serves as a barrier against external agents and prevents fluid loss. However, the skin is highly susceptible to damage, including burns caused by tissue damage due to heat. The WHO says burns cause about 180,000 deaths a year. But first and second-degree burns can be treated at home.This study developed an algae-based burn bandage with ginger and cucumber extracts in hydrogel to protect the wound from bacteria and facilitate skin regeneration. The study used a qualitative descriptive method to test the effectiveness of ginger and cucumber extracts in a hydrogel for wound treatment and the convenience of using biofilm.The tests included antimicrobial, skin irritation, solubility, biodegradable, elasticity, and organoleptic tests.The study found that the active components in the product can eradicate bacterial microbes, ensuring its safety, and dissolve in water within three days. The product's properties include elasticity, easy decomposition, a noticeable ginger aroma, a soft and chewy texture, and a slightly dark, clear color.

Abstract

The global energy crisis and demand for environmentally friendly energy have driven the development of alternative bioelectrochemical technologies, such as the microbial fuel cell (MFC). This study analyses the effect of soil moisture on the electrical power generated by the MFC system. The research was conducted at Trensains Muhammal High School in Sragen from September to October 2025, using simple linear regression analysis. The analysis shows a regression equation of Y = 1.83 + 0.82X with a coefficient of determination (R²) of 0.994, indicating that 99.4% of the electrical power variability is explained by changes in soil moisture. The regression model was declared valid based on the F test (Fcount = 1258.7; p < 0.05), t test (tcount = 35.48; p < 0.05), and classical assumption tests (p > 0.05). The MFC system can produce 38.2 mW on an area of 100 cm², which is sufficient to power low-power devices. This technology has significant potential for use in sustainable agriculture and achieving SDGs 7 and 13.
