UJI AKTIVITAS GABUNGAN NANOGOLD-NANOPLATINUM SEBAGAI SENYAWA TABIR SURYA DALAM KOSMETIK THE COMBINED ACTIVITY TEST OF NANOGOLD-NANOPLATINUM AS SUNSCREEN COMPOUNDS IN COSMETIC

Abstract

Abstrak. Telah dilakukan sintesis nanogold-nanoplatinum dengan variasi konsentrasi dan uji aktivitas sebagai senyawa tabir surya. Tujuan dari penelitian ini untuk mengetahui aktivitas tabir surya paduan nanogold-nanoplatinum. Konsentrasi larutan nanogold-nanoplatina yang digunakan antara lain 5, 10, 15, 20, 25, dan 30 ppm. Aktivitas tabir surya ditentukan dari nilai SPF sampel yang dianalisis menggunakan spektrofotometer UV-Vis. Hasil penelitian menunjukkan bahwa nilai SPF NPT  > SPF NG pada konsentrasi yang sama, nilai SPF gabungan NGPT  > NG < NPT yaitu sampel NG 5, NG 10, NG 15, NG 20, NG 25,  NG 30 yaitu 1.119; 6.572; 8.836; 9.313; 9.440; 10.732, sampel NPT 5, NPT 10, NPT 15, NPT 20, NPT 25, NPT 30 yaitu 16.795; 17.165; 17.781; 18.766; 18.860; 19.872, dan NGPT 5, NGPT 10, NGPT 15, NGPT 20, NGPT 25, NGPT 30 yaitu: 10,773; 11,072; 12,081; 15,958; 16,261;  16,320. Aktivitas tabir surya NGPT meningkat sebanding dengan peningkatan konsentrasi nanogold-nanoplatina dalam paduan. Berdasarkan hasil penelitian yang dilakukan dapat disimpulkan bahwa NGPT memiliki proteksi ultra (SPF ≥ 15) terhadap sinar UV B.

Abstract. The research has been done about synthesis of nanogold-nanoplatinum with a variation concentration and activity test as sunscreen compound. The purpose of this research is to find out the sunscreen activity of nanogold, nanoplatinum, and nanogold-nanoplatinum. The concentration of nanogold-nanoplatinum in 5, 10, 15, 20, 25, dan 30 ppm. Sunscreen activity determined by SPF value from samples analyzed using UV-Vis spectrophotometer. The results showed  that SPF  value of NPT  > SPF NG at the same concentration, the combined value SPF NGPT > NG < NPT of sample  NG 5, NG 10, NG 15, NG 20, NG 25,  NG 30 wich is 1.119; 6.572; 8.836; 9.313; 9.440; 10.732, sample NPT 5, NPT 10, NPT 15, NPT 20, NPT 25, NPT 30 wich16.795; 17.165; 17.781; 18.766; 18.860; 19.872, and NGPT 5, NGPT 10, NGPT 15, NGPT 20, NGPT 25, NGPT 30 wich is 10,773; 11,072; 12,081; 15,958; 16,261; and 16,320. Sunscreen activity of nanogold-nanoplatinum (NGPT) increases equal with increases concentration of nanogold-nanoplatinum in the solution. Based on the results of research it can be concluded that combination of nanogold-nanoplatinum (NGPT) have ultra protection factor (SPF ≥ 15) against UV B ray.
