Abstract
Natural ingredients that have sunscreen activity, namely galangal (Alpinia galanga) have a role in absorbing UV rays. Seaweed (Turbinaria. conoides) contains alkaloids, tannins, antioxidants, fucoxanthin. Many cases of skin damage due to harmful cosmetic ingredients and exposure to UV rays have encouraged the authors to explore the natural wealth of seaweed and galangal into skin care products. The aim of the study was to determine the optimum formulation and evaluate the best characteristics of seaweed and galangal sunscreen cream preparations. This research was experimental with four treatments and three replications giving concentrations of seaweed and galangal F0 (control), F1(1:1), F2(1:2), F3(2:1). The tests carried out included hedonic, homogeneity, centrifugal, viscosity, SPF, humidity and pH tests. The hedonic results show significant differences in color parameters (F3). All treatments produced cream type (O/W) and were homogeneous, there was no phase change in the centrifugal test. The viscosity and pH values meet the requirements and can moisturize, the highest SPF value (F2) is 3.67 in the minimum category. The more addition of seaweed affects the color characteristics. The more galangal added, the higher the SPF. Of all the treatments, the formulation with the addition of seaweed and galangal affected the characteristics of the resulting cream.

| Additional Information: | Bahan alami yang memiliki aktivitas tabir surya yaitu lengkuas (Alpinia galanga) berperan dalam menyerap sinar UV. Rumput laut (Turbinaria.conoides) mengandung alkaloid, tanin, antioksidan, fucoxanthin. Banyaknya kasus kerusakan kulit akibat bahan kosmetik berbahaya dan paparan sinar UV mendorong penulis untuk mengeksplorasi kekayaan alam rumput laut dan lengkuas menjadi produk perawatan kulit. Penelitian ini bertujuan untuk mengetahui formulasi optimum dan mengevaluasi karakteristik terbaik sediaan krim tabir surya rumput laut dan lengkuas. Penelitian ini bersifat eksperimental dengan empat perlakuan dan tiga ulangan dengan pemberian konsentrasi rumput laut dan lengkuas F0 (kontrol), F1(1:1), F2(1:2), F3(2:1). Pengujian yang dilakukan meliputi uji hedonik, homogenitas, sentrifugal, viskositas, SPF, kelembaban dan pH. Hasil hedonik menunjukkan perbedaan nyata pada parameter warna (F3). Seluruh perlakuan menghasilkan jenis krim (O/W) dan homogen, tidak terjadi perubahan fasa pada uji sentrifugal. Nilai viskositas dan pH memenuhi syarat dan dapat melembabkan, nilai SPF (F2) tertinggi adalah 3,67 pada kategori minimal. Semakin banyak penambahan rumput laut mempengaruhi karakteristik warna. Semakin banyak lengkuas yang ditambahkan, semakin tinggi SPFnya. Dari seluruh perlakuan, formulasi dengan penambahan rumput laut dan lengkuas berpengaruh terhadap karakteristik krim yang dihasilkan. | |||||||||
