Abstract

Paparan sinar ultraviolet (UV) yang berlebihan berpotensi menimbulkan kerusakan jaringan kulit, mempercepat penuaan, hingga meningkatkan risiko kanker kulit. Upaya pencegahan dilakukan melalui penggunaan tabir surya untuk membatasi penetrasi UV ke kulit. Dua sumber bahan aktif alami yang prospektif digunakan yaitu buah mahkota dewa dan rimpang kencur, buah mahkota dewa mengandung senyawa glukosida benzofenon yaitu phalerin dan rimpang kencur mengandung etil-parametoksisinamat yang merupakan senyawa turunan sinamat. Tujuan penelitian untuk menemukan konsentrasi emulgator yang optimal yang dapat meningkatkan stabilitas produk serta memperbaiki kinerja perlindungan terhadap sinar UV. Ekstrak diperoleh melalui proses maserasi menggunakan etanol96%, selanjutnya diformulasi dalam bentuk sediaan krim sebanyak 9 formula dengan variasi konsentrasi berbagai emulgator yaitu novemer, viscolam dan  tween 80-span 80 lalu dilakukan pengujian efektivitas tabir surya dari krim ekstrak dengan menghitung nilai %Te, %Tp, dan SPF. Hasil penelitian menunjukkan emulgator viscolam dengan konsentrasi 4% (formula VI) merupakan formula krim yang paling stabil berdasarkan parameter organoleptis, homogenitas, pH, tipe emulsi, viskositas, daya sebar serta daya lekat dan hasil pengujian tabir surya  dikategorikan sebagai proteksi ekstra dengan nilai %Te 3,83854 dan sunblock dengan nilai %Tp 2,703703 sedangkan nilai SPF 74,4323 yang memberikan efek proteksi ultra. Kata kunci: Ekstrak, Mahkota Dewa, Kencur, Emulgator, Tabir surya.

Abstract

The isotherm shorpsi curve is essential for estimating drying time, packaging, and material stability during storage. Based on the static method, the equilibrium moisture content of the material is obtained in a state of still air at a constant temperature. This research aims to make an incubator with constant temperature control. The method used in this study consisted of several stages, namely the design and assembly of the device, sensor calibration, and temperature rise testing. The results of the calibration of the tool show an average value of R2 = 0.998. This value indicates that the temperature readings from the sensor used with the mercury thermometer readings are very close. The temperature rise in the storage room experiences a constant increase until it reaches the setting point.

This type of research is Research and Development (RnD). The author used a quasi-experimental method with a one-group pretest-posttest design to identify the effect of treatment involving one group of subjects, namely the tenth-grade students of SMA Al Fattah Terboyo Semarang. Data were collected through digital literacy tests related to biology material and linked to digital literacy. The results of the study indicate that the use of e-booklets as learning media has a positive effect on improving students' digital literacy, as seen from the average pretest and posttest scores of the students, which increased from 65.83 to 81.50. This research suggests that further research can redevelop e-booklets into other interactive media to increase user involvement.
