Rumput laut memiliki beberapa aplikasi ekonomi dalam berbagai jenis industri, salah satunya untuk industri kosmetik. Salah satu kosmetik yang banyak digunakan yaitu krim tabir surya. Efektivitas dari krim tabir surya biasanya dinyatakan dengan nilai SPF (sun protection factor). Tujuan dari penelitian ini adalah untuk mengetahui kandungan senyawa aktif dan nilai SPF pada ekstrak rumput laut Turbinaria conoides dan Eucheuma cottonii yang dapat digunakan sebagai bahan aktif pada sediaan krim tabir surya. Hasil pengujian menunjukkan rumput laut Turbinaria conoides mengandung golongan senyawa fenol hidrokuinon, flavonoid, triterpenoid, steroid, dan saponin. Rumput laut Eucheuma cottonii hanya ditemukan senyawa alkaloid. Nilai SPF tertinggi pada rumput laut Turbinaria conoides terdapat pada ekstrak metanol (SPF 16.7), sedangkan untuk rumput laut Eucheuma cottonii terdapat pada ekstrak etil asetat (SPF 8.8). Hasil tersebut memperlihatkan bahwa ekstrak dari rumput laut Turbinaria conoides  dan Eucheuma cottonii memiliki potensi yang baik jika digunakan sebagai bahan aktif pada sediaan krim tabir surya.

Research on the combination of natural ingredients from brown seaweed and Moringa, to be used as sunscreen has been nothing. Therefore, the objective of this study was to determine the best formulation from sunscreen evaluation. In this study, the ratio of Moringa oleifera and Turbinaria conoides was 1:1 (cream L), 2:1 (cream M), 1:2 (cream N), and control (no added both of natural ingredients) (cream K). The evaluation of sunscreen cream by Sun Protection Factor (SPF) activity, viscosity, pH, homogeneity, and microbial test. SPF values in this study from cream K, L, M, and N were 0.75±2.31, 17.80±0.97, 9.48±1.41, and 15.97±2.38, respectively. Viscosity values were 22,400 cPs for cream K; 32,400 cPs for cream L; 26,000 cPs for cream M; and 32,800 cPs for cream N. The pH value of sunscreen cream in cream K, L, M, N were 7.30±0.02, 6.51±0.02, 6.38±0.04, and 6.43±0.04, respectively. In all of the treatments of sunscreen cream, microbial tests are absent and have good homogeneity. The ratio of 1:1 (cream L) between M. oleifera and T. conoides has a good synergistic effect to ward off UV B light, therefore cream L is the best sunscreen cream in this study.

Abstract-Acute and chronic exposure to nonphysiological doses of ultraviolet radiation leads to variety of changes of skin ranging from sun-burn, erythema to skin cancer. For skin protection from deleterious effects of sunlight, sunscreen products are used in various forms having chemical and physical filters. However, synthetic sunscreen formulations are reported to cause adverse effects. Thus the present study was planned to evaluate the sun protection factor (SPF) of leaves extract of Murraya koenigii for their application as herbal sunscreens. The results suggested that the occurrence of active compounds responsible for ultraviolet absorption can be extracted for use in sunscreens preparations as better, cheaper and safe alternative to harmful chemical sunscreens. Keywords: UV radiations, SPF, Murraya koenigii
