The effect of antioxidant aloe vera as a screen protector to decrease light intensity

ABSTRACT

The emergence of the Covid-19 pandemic had a major impact on education, resulting in an increase in the use of laptops. In order to minimize the acceleration of macular degeneration, it is necessary to develop technology to protect the surface of the screen, namely using the antioxidant aloe vera. It contains lutein and zeaxanthin. Aloe vera have anti-inflammatory effects and are found in the lens of the human eye. The purpose of this study was to prevent the occurrence of macular degeneration. The simple method used was conducted by aloe vera sonication following by mixing the aloe vera using TPU (thermoplastic polyurethane). All experiment was carried out through factorial design with two variables, i.e weight ratio of TPU and aloe vera and curing temperature. This research was statistically carried out by varying the weight ratio thermoplastic polyurethane/aloe vera (1-4) and temperature (30-40oC). The result showed the model was released significant in ANOVA assesment. Furthermore, testing the luxmeter as many as 13 screen protector variables then processed with a design expert application, obtained F-value data of 6.83 and P-value of 0.0127 (less than 0.0500). © 2023 Author(s).
