Study of Natural Dye from Golden Shower Pod for Development of UV Protection on Textile Product aimed to examine natural dyes obtained from Golden Shower Pod to produce naturally dyed fabrics as products. According to the research it was found that cationic additives which were soaked in a ratio of 20 grams per liter and boiled at 100 degrees Celsius for 20 minutes could help enhance the intensity of fabric dyes and the mordant used in this research which was soaked after dying was copper (ll) sulfate at concentration of 10 grams per liter for 30 minutes. According to appropriate tests the value of ultraviolet rays was excellent the dye fastness to artificial sunlight was moderate the abrasion was very good the dye fastness to acidic perspiration was good the dye fastness to alkaline perspiration was less and the dye fastness to water was good. According to the questionnaires returned it was found that the sample was interested in knitted apparel products most demands in the shade were darker tones and the apparel design concept chosen was mini dress with 1960s vintage style by matching dark and light brown of natural dyes of Koon pods. According to the assessment of satisfaction towards the products made from UV-resistant fabrics it was found that the form of products that are suitable to wear everyday was highest (58 percent) the form of the products that are appropriate for women in the age range 20-30 years was highest (66 percent) the arrangement of light - dark dyes of fabrics was highest (42 percent) the appropriateness of colors of embroidery threads was highest (58 percent) the appropriate relationship between patterns colors of embroidery threads and colors of fabrics was highest (76 percent) the appropriate placement of patterns was highest (40 percent) the appropriate size of patterns was highest (48 percent) the appropriate rhythm and continuity of patterns was highest (36 percent) the overall usability of products made from natural dyes that can block ultraviolet radiation was highest (82 percent) the appropriate relationship between embroidery patterns materials and fabrics was highest (12 percent) and the products (apparel) that can be worn at any occasion was highest (52 percent).
