Batik is one of Indonesia best heritage that need to be conserved. Since the inauguration of batik by UNESCO as World Heritage in 2009, batik in the international market continues to rise, so as to encourage the batik industry in Indonesia to increase its production. According to one of the batik entrepreneurs in Bandung, the number of batik production fluctuated depending on the season. In the rainy season, batik production decreased by 30%. The quality batik dye indigosol made dependent on the process of irradiation. When the intensity of the sun is low, the activation of the dye did not go well so that the quality of batik produced is low. In this research, several test was conducted to compare the result of irradiation using sun shines and ultraviolet on batik dye indigosol for some color. Ultraviolet irradiation is done by putting the cloth under the LED UV panels which is placed at a lightning frame. From the result, the most effective duration and intensity of irradiation by LED UV will be obtained for each indigosol color. The test result later will be processed by using spectrometry. At the design stage, machine prototype will be made. There are three major stages in the manufacture of prototypes, namely: the creation of irradiation system, creation of the framework, and system integration. Furthermore, an HMI (Human – Machine Interface) as a user interface for system is made. Based on the results of the performed test, the data showed that the intensity of ultraviolet irradiation is effective when the distance between the cloth and LED UV was adjusted to 10 cm for each color indigosol tested. Because the intensity generated by the LED UV panel is smaller than sunlight, ultraviolet radiation takes more time than the solar radiation for each color indigosol tested. Each data for any indigosol color was stored as a database so that the process of irradiation using machine prototype.
