ANALYSIS OF ORTHODOX BLACK TEA POWDER DENSITY USING THE TEA DENSIMETER METHOD AT PT PERKEBUNAN NUSANTARA I REGIONAL 2 KEBUN CIATER, KAB. SUBANG, PROV. WEST JAVA
Keywords:
Black tea, orthodox system, tea density, tea qualityAbstract
PT Perkebunan Nusantara I Regional 2 Ciater Plantation is engaged in the processing, management and marketing of black tea plantation products. The processing method used is the orthodox method, resulting in tea with a distinctive aroma and color. One of the quality control efforts on dry sorted tea products is the density test. Density is one of the indicators of tea quality control that affects the distribution and packaging process of tea powder. This study aims to determine the results of density analysis of orthodox black tea for 10 days, then determine the results of quality control with the P control map and determine the factors that cause density quality discrepancies. The method used in the density analysis of orthodox black tea is the tea densimeter method by tapping the powder 35 times. The result of powder density read in the measuring cup represents the volume of tea powder. The types of tea analyzed include BOPF, PFANN, Dust, PFANN II, Dust II and FANN II. The results showed that there were several deviations in the types of powder BOPF, PFANN, FII and Dust II which can be seen on the P control map. Factors that cause discrepancies in density values are the receipt and handling of raw materials. So it is necessary to do a good handling of raw materials by testing data worth processing in order to produce powder that meets the standards.
