Sappan wood (Caesalpinia sappan L.) is known to contain various bioactive compounds such as saponins, tannins, flavonoids, phenols, brazilin, and gallic acid. These compounds play an important role as antioxidants that can ward off free radicals and absorb UVA and UVB radiation that are harmful to the skin. Ultraviolet radiation is known to accelerate premature aging and cause tissue damage, so a topical formulation is needed that can provide protection while maintaining skin health. This study aims to determine the antioxidant activity and sunscreen ability of sappan wood extract in the form of lip balm with varying extract concentrations. Antioxidant activity was evaluated using the DPPH (1,1-Diphenyl-2-Picrylhydrazyl) method, while the Sun Protection Factor (SPF) value was determined by the Mansyur method using UV-Vis spectrophotometry. Sappan wood extract was formulated into four lip balm preparations, namely F0 (control without extract), F1 (5%), F2 (10%), and F3 (15%). Physical tests including homogeneity, pH, spreadability, adhesiveness, and organoleptic were conducted to ensure the quality of the preparation. The results showed that sappanwood extract had an IC50 value of 23.62 ppm which was categorized as very strong antioxidant activity. In the lip balm formulation, the IC50 values ​​obtained were F0 = 246.76 ppm (very weak), F1 = 92.68 ppm (strong), F2 = 78.03 ppm (strong), and F3 = 63.58 ppm (strong). The SPF test showed a protection value of F0 = 2.11 (minimum), F1 = 13.64 (maximum), F2 = 14.25 (maximum), and F3 = 18.28 (ultra). Thus, lip balm made from sappanwood extract has the potential as a cosmetic preparation that not only meets physical criteria, but also provides high antioxidant activity and effective sunscreen protection.

The central building of the cyber world in the city center plays a significant role in enhancing community activities, providing social space, and contributing to the city's image. As the first shopping center in Palembang City, International Plaza has historical and strategic value in the city's development. However, over time, the attractiveness of International Plaza has decreased significantly. This decline is caused by several factors, such as the development of new, more modern shopping centers and the lack of updates to the building's design elements that can attract visitors. This study aims to analyze the potential for redesigning International Plaza with a local cultural approach. In this redesign concept, the Sarinah Building in Jakarta is used as a comparative study because it has successfully combined modern concepts with the development of traditional elements that reflect local culture. The Sarinah Building, although designed with a modern approach, still maintains cultural values relevant to the surrounding community, thus creating a space that is not only functional but also has visual and emotional appeal for its visitors. The results of the study indicate that with a modern architectural approach that remains based on local culture, International Plaza has the potential to revitalize and attract visitors. The suggested redesign includes changes to the building's facade by adding ornaments typical of Palembang City, such as traditional carvings or motifs that reflect the richness of local culture. These ornaments can be applied using secondary skin techniques to building facades, which not only enhance aesthetics but also serve as sunscreens. Furthermore, zoning and tenant order are crucial for a more organized and comfortable visitor flow. Finally, enhancing the public space at the front of the building with additional public facilities, gardens, and gathering areas can create a more vibrant and enjoyable atmosphere for visitors.

Ultraviolet (UV) radiation has been known to cause various adverse effects on the skin, including erythema (commonly referred to as sunburn), premature aging, and, with prolonged exposure, the risk of developing skin cancer. To counteract these harmful effects, sunscreen products are commonly used to protect the skin from UV radiation. The development of natural-based sunscreens is gaining attention due to their potential safety and antioxidant benefits. One promising natural ingredient is thyme (Thymus vulgaris L.), a medicinal herb that contains several secondary metabolites such as flavonoids, alkaloids, and tannins. These compounds possess antioxidant and free radical scavenging properties, making them suitable candidates as active ingredients in sunscreen formulations. This study aims to determine the Sun Protection Factor (SPF) value of thyme herb extract using the UV-Vis spectrophotometric method. A qualitative approach was used to assess the photoprotective potential of the extract. The SPF values were measured at three different concentrations of the extract: 0.5%, 0.75%, and 1.0%. The absorbance of each concentration was recorded at wavelengths ranging from 290 nm to 400 nm using a UV-Vis spectrophotometer. The SPF values were then calculated based on the absorbance data processed using Microsoft Excel. The results revealed that the thyme herb extract exhibited high SPF values at all tested concentrations. Specifically, the SPF values obtained were 36.027 for 0.5%, 36.244 for 0.75%, and 36.516 for 1.0% concentration. All three concentrations fall under the "ultra protection" category, indicating strong UV protective potential. These findings suggest that thyme herb extract can be effectively utilized as a natural active ingredient in the formulation of sunscreen products. Further studies are recommended to explore its stability, safety, and efficacy in topical applications.

Sunlight is the main source of energy for life, but ultraviolet radiation can have negative impacts on the skin, such as sunburn, pigmentation, wrinkles, premature aging, and the risk of skin damage due to excessive exposure. One way to protect the skin from these effects is to use sunscreen. Carrots contain antioxidant compounds that can bind free radicals and prevent cell damage due to oxidation, so they have the potential to be used as a natural ingredient in making sunscreen. This research aims to formulate and test the physical properties of carrot extract lotion as a sunscreen and determine the extract concentration that has the optimal Sun Protection Factor (SPF) value. The method used is experimental by making lotion formulations, testing their physical properties, and measuring the SPF value of each formulation. The research results showed that the KN, F1, F2, and F3 lotion formulations had a semi-solid form which met the formulation requirements. However, KN's SPF value is only 1.23 which does not meet sunscreen standards. Meanwhile, F1 has SPF 8.3 (extra effect category), F2 with SPF 15.06 and F3 with SPF 24.1 (ultra category). F3 shows the best results because with SPF 24.1, this formulation is close to SPF 25 which can protect the skin for up to 4 hours with twice daily use. The higher the concentration of carrot extract, the better its effectiveness in lotion formulation as a sunscreen.

High exposure to sunlight in tropical areas such as Indonesia increases the risk of skin damage due to ultraviolet (UV) radiation. Sunscreen functions to protect the skin from the bad effects of UV rays, and a good level of knowledge is expected to increase awareness of its use. Surf trainers, who are frequently exposed to sunlight, need proper knowledge and awareness to prevent these negative impacts. This research aims to determine the relationship between the level of knowledge and awareness of the use of sunscreen among surfing trainers at Kuta Beach. The research used an observational design with a cross-sectional approach. The sampling technique used the accidental sampling method with a total of 57 respondents. Data was collected using a questionnaire, and data analysis was carried out using the Spearman correlation test using SPSS version 25. The results showed that 96.49% of respondents had a good level of knowledge, while only 3.5% of respondents had awareness of the use of sunscreen, which was a very low percentage. The results of statistical analysis show that there is no significant relationship between the level of knowledge and awareness of the use of sunscreen with a significance value of 0.469 (p > 0.05).
