| dc.description.abstract | Penggunaan smartphone menghasilkan radiasi panas dan elektromagnetik
yang berbahaya, sehingga diperlukan pelindung untuk mengurangi efek tersebut.
Tanaman lidah mertua (Sansevieria trifasciata) diketahui dapat menurunkan radiasi
elektromagnetik pada beberapa peranti elektronik. Penelitian ini bertujuan
menetapkan formula film PVA-ekstrak terbaik dari lidah mertua untuk pelindung
smartphone yang menurunkan efek radiasi secara optimal. Formula film dibuat
dengan meragamkan volume akhir film, nisbah PVA: ekstrak, serta konsentrasi
ekstrak. Radiasi panas diuji dengan PASCO CI-6505B dan radiasi elektromagnetik
dengan GM-3120. Ekstrak terbaik dari uji radiasi adalah ekstrak aseton dalam
volume film 100 mL. Nisbah terbaik dihasilkan oleh film dengan rasio PVA:ekstrak
aseton 1:2, dan konsentrasi aseton terbaik, ialah 5%. | id |
| dc.description.abstract | Smartphone produce harmful heat and electromagnetic radiation that need
protection to reduce their effects. Sansevieria trifasciata is known to lower
electromagnetic radiation on some electronic equipment. The study aimed to
determine the best formula for PVA-extract of S. trifasciata that optimally lowers
the effects of radiation. The films were prepared with various formulas by varying
the final volume of the film, the ratio of PVA:extract and the concentration of the
extract. Heat radiation was tested with PASCO CI-6505B and electromagnetic
radiation with GM-3120. The best extract from the radiation test is acetone extract
in a film volume of 100 mL. The best ratio produced by the film with the ratio of
PVA:acetone extract is 1:2 and the best acetone concentration is 5%. | id |
