TEUKU AKRAM RAFI. Pengaruh Penambahan Hidroksiapatit Terhadap Kinerja
Perlindungan Uv dan Biokompatibilitas pada Tabir Surya. Dibimbing oleh YESSIE
WIDYA SARI dan YULIATI HERBANI.
HAp merupakan material biokompatibel yang berpotensi digunakan sebagai
bahan tambahan dalam formulasi tabir surya. Penelitian ini bertujuan untuk
mengevaluasi pengaruh penambahan HAp terhadap kinerja perlindungan
ultraviolet (UV), dan sifat fisik tabir surya. Hidroksiapatit disintesis dari cangkang
telur ayam melalui metode kalsinasi dan titrasi, kemudian dikarakterisasi
menggunakan X-ray Diffraction (XRD) dan Scanning Electron Microscopy (SEM).
Tabir surya diformulasikan dalam sistem emulsi minyak dalam air (O/W) dengan
variasi konsentrasi HAp sebesar 1%, 3%, dan 5% (b/b). Pengujian meliputi analisis
spektrum UV-Vis dan perhitungan nilai Sun Protection Factor (SPF) menggunakan
metode Mansur, pengujian pH, serta pengukuran sudut kontak. Hasil penelitian
menunjukkan bahwa penambahan HAp menyebabkan penurunan nilai absorbansi
UVB dan nilai SPF seiring dengan peningkatan konsentrasi HAp. Namun demikian,
penambahan HAp mampu meningkatkan stabilitas fisik dan karakteristik
pembasahan permukaan tabir surya. Formulasi dengan konsentrasi HAp 3%
menunjukkan kestabilan fisik terbaik, nilai pH yang mendekati pH kulit, serta
viskositas yang optimum. Berdasarkan hasil penelitian, dapat disimpulkan bahwa
hidroksiapatit berpotensi sebagai bahan tambahan dalam formulasi tabir surya
dengan konsentrasi optimum sebesar 3% (b/b).

Performance and Biocompatibility of Sunscreen. Supervised by YESSIE WIDYA
SARI and YULIATI HERBANI.
HAp is a biocompatible material with potential applications as an additive
in sunscreen formulations. This study aims to evaluate the effect of HAp addition
on ultraviolet (UV) protection performance and physical properties of sunscreen.
Hydroxyapatite was synthesized from chicken eggshells via calcination and
titration methods and characterized using X-ray Diffraction (XRD) and Scanning
Electron Microscopy (SEM). Sunscreen formulations were prepared as oil-in-water
(O/W) emulsions containing HAp at concentrations of 1%, 3%, and 5% (w/w).
Performance evaluation included UV–Vis spectroscopic analysis and Sun
Protection Factor (SPF) determination using the Mansur method, pH measurement,
physical stability testing, and contact angle analysis. The results indicate that
increasing HAp concentration leads to a decrease in UVB absorbance and SPF
values. However, HAp addition improves the physical stability and wettability
characteristics of the formulations. The sunscreen containing 3% HAp exhibited the
most favorable balance between viscosity, and skin-compatible pH. These findings
suggest that hydroxyapatite is a promising additive for enhancing the stability and
physical properties of sunscreen formulations, with an optimal concentration of 3%
(w/w).
