This research focuses on the use of tannin components in tamarind seed coats as a mordant and natural dye in cotton fabrics. Tannins were extracted from the tamarind seed coat by boiling method and then the tannin content was determined. The tannin extract was then used as a natural mordant with the addition of metallic copper sulfate (CuSO4) mordant. Tannin extract is also used as a dye on fabrics with the addition of sodium sulfate (NaSO4). The color strength of the tannins in the fabric was analyzed using a spectrophotometer from the rinse water. The results showed that the cloth that had been given the mordant had a stronger color strength than the cloth without the mordant. The use of mordant was varied at concentrations of 5, 10, 15, 20, and 25%-owf. The results of the analysis showed the most optimum tannin concentration at 15%-owf. The concentration of tannin used in the coloring process was also varied at concentrations of 5, 10, 15, 20, and 25%-owf. The results of the analysis show that the concentration of tannin used in the dye does not affect the strength of the color, but only affects the brightness of this color.

Internal medicine is a disease that usually attacks humans. Most of the internal diseases that occur are often considered trivial, and if the disease is not treated immediately it will become more serious and serious. So because of that we need a tool or system that has the ability like a doctor in diagnosing this internal disease. The system is an expert system that solves problems as is usually done by experts. This study aims to create an expert system application for diagnosing internal medicine. The application of this system diagnoses internal medicine with the Prototype and the Certainty Factor method. The Certainty Factor method is a method for proving whether a fact is certain or uncertain. This method provides space for experts to give confidence in the knowledge they express. From calculations using the Centainty factor method for each disease, from the symptoms entered by the user for hypotension the probability is 0.92% or 92%, while the symptoms entered by the user for hypertension are likely to be 0.994624 or 99.46%, from the results of the comparison the probability is obtained the maximum value of CF is 0.994624 or 99.46% with hypertension.
