Sansevieria trifasciata (mother-in-law's tongue), an ornamental plant widely found in Indonesia, can absorb electromagnetic radiation in various electronic devices. This study aims to find the best S. trifasciata extract as an electromagnetic and thermal radiation reducer emitted from a smartphone. S. trifasciata leaves were macerated using ethanol, acetone, and dichloromethane. The extract was mixed with PVA as a film and tested for electromagnetic radiation using a radiation measuring device type GM-3120. Thermal radiation was tested using a temperature sensor (PASCO CI-6505B) connected to a PASCO 550 Universal Interface. All smartphone protective films decreased radiation from the smartphone, and the acetone extract caused the most significant radiation decrease, with the best results at a concentration of 5%. An S. trifasciata extract contained alkaloids, saponins, steroids, phenolics, and tannins based on the phytochemical tests. Based on LC-MS data, the dominant compounds identified from the three extracts of S. trifasciata is a group of alkaloids, fatty acid, and steroid. The functional groups that are thought to play a role in reducing radiation are the C-O, C=O, and C-OH functional groups. A compound that is thought to contribute to the reduction in radiation is neuroscogenin, a steroid group.

“…Laurentii were reported to reduce exposure to electromagnetic radiation from television for one hour [16]. Another study reported that the extract could reduce indoor electromagnetic radiation by up to 16% [17]. Likewise, an anti-radiation bio screen made of this species can reduce radiation from laptops by 24.45% [18].…”

Entering the digital era, the culture of human life is increasingly inseparable from the use of electromagnetic waves which are very useful in supporting human life, but in the other side, it also has negative impacts in the form of radiation that threatens human health. Only few people realize that ornamental plants have many benefits other than as a decoration inside or outside the room. Several types of ornamental plants have the ability to absorb electromagnetic radiation emitted by electronic equipment. In this simple physics research, measurements were made to compare the absorption of several types of ornamental plants to electromagnetic wave radiation, those are karet kebo, betel, succulent, ivy plant, and snake plant. The research results show that snake plant’s ability to absorb electromagnetic wave radiation is the greatest than others. Research conducted on ivy shows that the absorption of ornamental plants to electromagnetic wave radiation is influenced by the distance of the plant to the radiation source, where the closer the distance between the ornamental plants to the source of electromagnetic wave radiation is, the greater the absorption of radiation occurs, resulting in a decrease in the intensity of electromagnetic radiation also getting bigger. The trend of changes in the absorption of electromagnetic wave radiation shows a decrease in each increase in distance according to the exponential graph.
