      Abstract
      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). Kata kunci: hidroksiapatit, perlindungan UV, SPF, tabir surya
       
      TEUKU AKRAM RAFI. The Effect of Hydroxyapatite Addition on UV Protection 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). Keywords: hydroxyapatite, sunscreen, UV protection, SPF
