“…Efektivitas sediaan dalam melindungi kulit dari radiasi sinar UV biasanya dinyatakan dengan nilai SPF (Aulia et al, 2014). SPF merupakan indikator universal yang menjelaskan tentang keefektifan produk atau zat yang bersifat UV protektor (Rahmawati, Muflihunna, & Amalia, 2018). Mekanisme kerja dari flavonoid sebagai antioksidan dapat dilakukan dengan dua cara yaitu secara langsung maupun tidak langsung.…”

“…Untuk mengetahui efektivitas suatu sediaan tabir surya dinilai dalam faktor proteksi cahaya yang dinyatakan dengan nilai Sun Protection Factor (SPF). Nilai SPF merupakan indikator tentang efektivitas kemampuan suatu produk yang bersifat UV protektor (Rahmawati et al, 2018). Tujuan dari tabir surya ialah mencegah kulit terbakar dan kerusakan kulit yang disebabkan radiasi sinau UV.…”

“…Menurut Rahmawati et al (2018) kategori tingkat kemampuan tabir surya berdasarkan perhitungan Mansur dibagi menjadi 5 yaitu SPF minimal (2-4), SPF sedang (4-6), SPF ekstra (6-8), SPF maksimal (8-15) dan SPF ultra ≥ 15. Berdasarkan data SPF yang diperoleh menunjukan bahwa pada formula basis krim metode Mansur memiliki rerata nilai SPF 0,59±0,225 dan menunjukkan bahwa, formula basis tidak memiliki efektivitas tabir surya karena berdasarkan Rahmawati et al (2018) hasil nilai SPF tidak masuk kriteria pembagian tingkat tabir surya. Pada formula I ekstrak 5% etanol 70% daging buah labu kuning berdasarkan perhitungan SPF metode Mansur memiliki rerata 2,83±1,164 sehingga, memiliki tingkat kemampuan minimal (2-4) tabir surya (Rahmawati et al, 2018).…”

Kosmetik perawatan kulit wajah yang banyak digunakan tersedia dalam berbagai bentuk, salah satunya yaitu bentuk sediaan krim. Kandungan flavonoid buah labu kuningmemiliki potensi dari labu kuning sebagai antioksidan dan tabir surya dimanfaatkan dalam bentuk sediaan krim yang sangat praktis penggunaannya. Efektivitas sediaan dalam melindungi kulitdari radiasi sinar UV biasanya dinyatakan dengan nilai SPF. Tujuan dari penelitian ini yaitu untuk mengevaluasi sifat fisik sediaan krim ekstrak etanol 70% daging buah labu kuning (Cucurbita maxima D.) dengan konsentrasi berbeda dan penentuan nilai Sun Protection Factor (SPF) secara in vitro menggunakan spektrofotometri UV-Vis. Penelitian ini menggunakan metode eksperimental. Daging buah labu kuning (Cucurbita maxima D.) yang telah dilakukan ekstraksi menggunakan metode maserasi kemudian dilanjutkan pembuatan formulasi krim dan penentuan nilai Sun Protection Factor (SPF) secara in vitro dengan metode Mansur dan A.J. Petro. Hasil uji sifat fisik sediaan krim memenuhi persyaratan sediaan krim yang baik kecuali pada uji daya sebar karena kurang dari 5-7 cm. Nilai SPF sediaan krim pada formula basis(0%), formula I (5%), formula II (10%) dan formula III (15%) memiliki rerata nilai SPF 0,59±0,225 (tidak memiliki efektivitas tabir surya), 2,83±1,164 (minimal), 4,43±0,266 (sedang), 6,98±0,099 (ekstra) berdasarkan perhitungan Mansur dan 1,28±0,132 (bukan merupakan tabir surya), 3,80±2,003 (minimal), 7,55±0,913 (minimal), 25,22±1,493 (sedang) berdasar perhitungan A.J. Petro. Sediaan krim ekstrak etanol 70% daging buah labu kuning dengan konsentrasi 0%, 5%, 10% dan 15% memiliki sifat fisik yang kurang baik, pada uji daya sebar tidak masuk kriteria krim yang baik 5-7 cm. Peningkatan konsentrasi ekstrak etanol 70% daging buah labu kuning memberikan nilai SPF yang berbeda.Kata Kunci : Krim, Daging buah labu kuning, SPF

“…Chronic exposure to ultraviolet rays from the sun will result in changes in the structure, composition of the skin and oxidative stress on the skin. Effects such as erythema, pigmentation and photosensitivity, as well as long-term effects in the form of premature aging and skin cancer [3]. UV radiation is divided into 3 types based on their wavelength.…”

Background. Ultraviolet light is an electromagnetic wave emitted from sunlight which is divided into 3 wavelengths. UV wavelengths, divided into UVA rays, UVB rays and UVC rays. UVC rays will be trapped in the ozone layer and UVA radiation can reach (90-95%) while at UVB will be less (<10%). The body needs special protection from UV radiation, especially on organs that are exposed to direct sunlight, namely the skin. Sunscreen is a compound that functions as skin protection from excessive sun exposure, especially from exposure to ultraviolet (UV) rays. Sunscreen is divided into 2 types, namely physical sunscreen and chemical sunscreen.Aim. This study aimed to investigate the level of knowledge of junior high school students about the effects of UV radiation and the use of sunscreen.Research methods. This study uses a descriptive observational research method with a cross sectional approach that describes the level of knowledge of junior high school students about the effects of UV radiation and the use of sunscreen. Sampling will be carried out at one time using data collection techniques through questionnaires. The data obtained will then be processed and analyzed with the SPSS computer program. Results. The total samples we investigated were 223 respondents. As many as 61% of respondents have a sufficient level of overall knowledge. The level of knowledge of respondents about the effects of UV radiation on the skin is in the sufficient category with a percentage of 62.3%. The level of knowledge of students regarding the use of sunscreen on the skin is in the sufficient category with a percentage of 55.2%. Conclusion.The level of knowledge of the students of public junior high school 2 in Pematangsiantar city for the academic year 2021/2022 as a whole is at the level of knowledge in the sufficient category.

“…Indonesia is a tropical country with abundant sun exposure throughout the year so Indonesia has an ultraviolet index above 11, which means it has an extremely dangerous risk (BMKG, 2021). Ultraviolet radiation can cause damage to the skin (Rahmawati, Muflihunna, and Amalia 2018). Not only that, but global warming can also increase exposure to ultraviolet rays that enter the earth (Mumtazah et al 2020).…”

Indonesia is a tropical country with an ultraviolet index above 11, coupled with global warming causing the level of ultraviolet radiation to increase. This has great potential to cause damage to the skin. Therefore, sunblock protects the skin from the dangers of exposure to UV rays. cosmetic products sunblock is accompanied by the circulation of various sunblock made from synthetic chemicals which of course can endanger health. Based on these problems, the authors created an innovative sunblock from bandotan root extract and basil leaves. This type of research is descriptive analysis with literature review. Based on the studies that have been carried out, it is known that bandotan root extract (Ageratum Conyzoides Linn) has the potential as a sunblock because it contains tannins and flavonoid compounds that can absorb UV A rays at a concentration of 150 ppm. While the basil leaf extract (Ocimum sanctum L) can absorb UV B rays because there are flavonoid and phenol compounds SPF 8.58 is obtained at a concentration of 0.03%. Bandotan root and basil leaf extracts were obtained through maceration and evaporation techniques, while rose water as a solvent was obtained by distillation techniques. The results obtained, namely: (1) increasing the usability of bandotan roots and basil leaves; (2) reducing pathological risk from harmful UV rays; (3) alternative for making sunblock made from natural and halal ingredients. Thus, sunblock is eco-friendly.
