Propolis INTRODUCTION Antioxidants play a vital role in skin health, particularly in the physiological and chemical contexts of free radical damage. Free radicals, generated by UV exposure, pollution, and normal metabolic processes, can cause cellular damage that contributes to premature aging and various skin disorders. This damage occurs as free radicals attack critical components of the skin, such as collagen and elastin, leading to loss of firmness and Air pollution and UV rays can cause free radicals in the human body, these free radicals cause several degenerative diseases such as cancer, aging, rheumatoid arthritis, autoimmune. One of the causes of skin damage is free radicals in the form of ultraviolet rays and air pollution. Biofarmasetikal Tropis (The Tropical Journal of Biopharmaceutica. 2024, 7. , 8-14 By neutralizing free radicals, antioxidants like vitamins C and E not only protect the skin from oxidative stress but also support cellular repair processes and reduce In excessive conditions. UV rays can cause several skin problems, ranging from redness, pigmentation, and in the long term can cause the risk of cancer. Therefore, consuming antioxidant-rich foods and using skincare products containing these compounds are essential strategies for maintaining healthy skin and preventing signs of aging. Skin care is very necessary so that the skin is not exposed to excessive free radicals effect. One way to overcome this problem is to use a lotion as moisturizer to prevent free radical effect. The active substances contained in lotion preparations is a moisturizer3. Lotion contains ingredients that can moisturize the skin. Lotion consists of moisturizers, emulsifiers, cleansers, active The advantages of lotion are that with a fairly large air content, the lotion dosage form is easy to apply, the spread and penetration power are quite high, it does not cause an oily feeling, has a cooling effect, and is also easy to to wash with air. There are many lotions circulating in the community that contain various benefits, one of which is that it can moisturize the skin4. Lotions containing antioxidants can moisturize the skin. Lotion is a preparation that is applied in liquid form which can be in the form of a dispersion or suspension, where the main ingredient is included in the type of oil-in-water emulsion so that it is easily rinsed with air and is not sticky and easy to apply to the skin so that it is quickly absorbed with even results5. People are increasingly interested in exploring moisturizing lotions from natural ingredients, because natural ingredients are easy to obtain and have fewer side effects, so utilizing plants to make lotions has become an innovation that is popular with the public. Natural ingredients that have the potential to moisturize the skin are the leaves of the Sonneratia caseolaris plant. This plant is usually used in traditional medicine, especially in the province of South Kalimantan. Sonneratia caseolaris has various properties that have been empirically proven to be able to cure various diseases, including wound and flu e-ISSN 2685-3167 p-ISSN 2828-6685 Sonneratia caseolaris is very well known in Kalimantan Island because its fruit can be eaten and its leaves are also used to treat smallpox, treat diarrhea and treat bruises on the Sonneratia caseolaris extract contains secondary metabolites which are one of the medicinal ingredients and have a molecular structure and various biological activities7,8. Other natural ingredients from Trigona sp propolis bee products are also effective as antioxidants, antitoxins, antibiotics, and improve the immune system9. Compounds in Trigona sp propolis can fight free radicals, these compounds are bioactive compounds containing phenolics and flavonoids10,11. This stingless bee product has not been optimally utilized, therefore this research focuses on the combination lotion formula of stingless bee propolis and Sonneratia caseolaris leaves as a antioxidant agent to prevent free RESEARCH METHODS The materials used in this study were Sonneratia caseolaris leaves and Trigona sp Propolis.

Heat the water phase, namely methyl paraben, propoil paraben, glycerin. TEA above a water bath at a temperature of 70-80 EE. Mix the dissolved water phase with the carbopol that has been developed above the water bath until mass I is Then heat the oil phase, namely cetyl alcohol, liquid paraffin, stearic acid at a temperature of 70-80 EE in a water bath and stir until dissolved (Mass II). Mass I and II are mixed, stirred using a stamper until they form a lotion base. After that, variations in the comparison concentration are added little by little, stirred until homogeneous. The preparation that has been made is put into the prepared lotion then diluting it with 10 ml of distilled water. From the SNI 16-4399-1996 standard, the pH of the formulation is related to skin comfort when used, but the pH of the topical formulation should not be too acidic because it can cause skin The pH range that can be tolerated by the skin is 4. Homogeneity Test The homogeneity was observed by the particles of the lotion whether there were still coarse grains in the lotion preparation. This test was carried out by applying the lotion to a petri dish to evaluate the homogeneity of the lotion that had been made, with the aim of determining whether the preparation was homogeneous or Spreading Power Test This spreading power test was used 0. grams of sample. This preparation was placed in a petri dish that had been coated with scaled graph paper. Then given a glass weight load until the weight reaches 125 grams, and left for 1 minute, then measured the diameter of the lotion. The range of good lotion preparation diameter is 5-7 cm15. Stability evaluation Organoleptic Test Organoleptic testing was conducted through visual observation of the shape, color and aroma of the lotion preparation which was carried out visually from the three lotion preparation formulations that had been made14. pH Test The pH measurement test was carried out using a pH meter. The pH test was carried out by 1 grams of Sonneratia caseolaris ethanol extract lotion and Trigona sp propolis Antioxidant Activity Test In the antioxidant activity testing stage in this study, using a combination lotion of Sonneratia caseolaris ethanol extract and Biofarmasetikal Tropis (The Tropical Journal of Biopharmaceutica. 2024, 7. , 8-14 Trigona sp Propolis with three formulas with a comparison of concentration variations, each formula was weighed at 10 mg, then dissolved with methanol pa in 10 ml of a measuring flask, then producing a parent concentration of 1000 Next, a dilution was carried out to make a series of test solution concentrations with a concentration range of 60, 70, 800, 90, 100 ppm. Each series of concentrations was added with 3 ml of 50 ppm DPPH solution. The solution mixture was homogenized and incubated for 30 minutes in a dark room.

Sample absorbance was calculated using the sample absorbance value from the DPPH absorbance value 16. RESULTS AND DISCUSSION Evaluation of the results was obtained in Table 2 with the organoleptic characteristics of formula 1, 2, 3, namely with a thick texture, distinctive aroma, light green color. This organoleptic test must show no change or separation of the emulsion phase and no color changes and the emergence of a rancid odor17. Table 2. Evaluation of Lotion Formula from S. caseolaris Leaves and Trigona sp. Bee Propolis Extract Parameter Texture Aroma Color Homogeneity Spreadability Formula Thick distinctive aroma Ivory white Homogeneous 6,3 cm Thick distinctive aroma Ivory white Homogeneous 5,85 cm The distinctive aroma found in the lotion can attract consumers in choosing the formula. The characteristics of a product, such as its scent, can significantly influence user experience and preferences, particularly in skincare products like lotions. Aroma plays a crucial role in evoking emotions and memories, which can enhance overall satisfaction with a product. Studies have shown that pleasant scents can improve mood and create a positive association with the product, leading to increased likelihood of repurchase18. The ivory white color of this lotion preparation is obtained from the color of the ethanol extract of Sonneratia caseolaris leaves that contains chlorophyll so that the resulting color is green, the color of the Trigona sp Propolis extract is brown, but this color does not appear too much in each preparation so that the more dominant color that appears in the preparation is ivory white, the comparison of concentrations does not show significant differences in preparations such as texture, aroma, and color19. The pH test shows the average of the pH of Formula 1, 2, 3. This pH test uses a pH meter Thick distinctive aroma Ivory white Homogeneous 5,75 cm that has been calibrated using pH 7. Which needs to be known that the skin pH requirement is 4. 58 because if the lotion preparation is too acidic, the preparation will irritate human skin. Formula 1 gets an average value after 3 repetitions of 7. formula 2 gets an average result after 3 repetitions of 7. 1, formula 3 gets a result of 7. The rise and drop of pH can be caused by environmental factors, unstable temperatures and unstable extracts in the preparation. The results of pH testing of all formulas have met the pH requirements on the skin20,21. The homogeneity test aims to see if there are any coarse grains in the lotion preparation. The test results for formulas 1, 2, 3 showed a homogeneous preparation where the preparation was spread on a clear petri dish so that the form of the preparation did not have coarse grains. This is in line with research. Which states that a good lotion preparation does not have coarse This spreadability test aims to determine how widely the lotion preparation is spread. The test results show that the lotion preparation combination of Sonneratia caseolaris ethanol extract and Trigona sp Propolis from formula 1 Biofarmasetikal Tropis e-ISSN 2685-3167 p-ISSN 2828-6685 (The Tropical Journal of Biopharmaceutica. 2024, 7. , 8-14 has a diameter of 5. 8 cm, formula 2 has a diameter of 6. 3, formula 3 has a diameter of 5. Of the three formulations, formula 2 is the best in terms of the spreadability value obtained compared to formulas 1 and 3. Of the three formulas that have been made, the spreadability of this lotion has met the requirements of the previous journal which states that the spreadability of topical preparations is 5-7 cm23. % Inhibition Control ( ) Formula 1 Formula 2 Formula 3 Concentration . Figure 1. Free radical inhibition of lotion combination from Sonneratia caseolaris leaves dan Trigona sp Bee Propolis Extract (F1 1:1. F2 2:1. F3 1:. DPPH is a chemical compound that is widely used in testing antioxidant activity. When DPPH meets free radicals, it will undergo a soaking reaction with a color change from dark purple to pale yellow or colorless. In this process, it is an indication that free radicals have been captured and neutralized by the antioxidant test compound being tested 24. The more DPPH compounds that have been stabilized by secondary metabolite compounds in the sample, the more the color intensity will change. The lower the concentration, the more the color will fade, thus reducing the antioxidant value and indicating an increase in the antioxidant value25. Ascorbic acid is a natural antioxidant that is widely used for its activity in preventing free radicals and avoiding oxidative damage. When ascorbic acid reacts with DPPH radicals, the reaction can be predicted well so that it can facilitate the interpretation of test results. Ascorbic acid has strong and stable antioxidants so that it can be used in testing as a comparative sample 26. The antioxidant activity of the combination lotion preparation of Sonneratia caseolaris and Trigona sp Propolis was tested using the DPPH method with UV-Vis Spectrophotometry at a maximum wavelength of 517 nm. Based on the results of antioxidant testing on each preparation with Formula 1 ratio . : . Formula 2 ratio . : . and Formula 3 ratio . : . obtained a free radical inhibition value with very strong antioxidant activity. The results of antioxidant testing at a concentration of 60 ppm showed that formula 3 was better than formula 2 and 3, while at a concentration of 100 ppm it was seen that all three formulas had almost the same inhibition ability as the positive control . scorbic The higher the concentration of the sample and positive control, the lower the absorption value and the higher the inhibition value This shows that the higher the concentration of the sample, the free radicals will be inhibited. This result is in line with the results of the antioxidant test obtained from the ethanol extract of Sonneratia caseolaris, as well as the Trigona propolis extract 27,28. The combination of these two natural ingredients shows increased antioxidant activity and shows similar activity after being made into a lotion29.
