Product development of black Piper retrofractum Vahl tea (black PrV tea)

Abstract

Java long pepper or black PrV is one of the herbal plants that have active compounds and are beneficial for health. Almost all herbal medicine industries use black PrV only as supporting material, so it is necessary to develop new products with black PrV as the basic material. This study aims to determine the attributes of customer requirements and the dominant technical requirements in the production of black PrV tea using Quality Function Deployment (QFD) method. Then the experiment was carried out using the technical requirements with the highest weight as a factor. Experiments were carried out using Completely Randomized Design with two factors, namely type of supporting material and proportion of black PrV. The result showed that customers wanted black PrV tea that was not too peppery, natural taste, nice colour and flavour, and quick brewing time. The dominant technical requirements are the type of supporting material and proportion of black PrV. The best of supporting material is secang wood and the proportion of black PrV is 80%.
