Conventional drying methods can be improved by utilizing geothermal energy and the addition of Zeolite-A as an absorbent from the synthesis of Kaolin, which has abundant resources in Indonesia. The use of geothermal energy for fossil energy substitution results in the development of more sustainable and safer environmentally, while the use of Kaolin as absorbent will increase economic value and reduce the export of raw materials in Indonesia. This research was conducted to study the effect of adding Zeolite-A to the heat pipe heat exchanger (HPHE) system that utilizes geothermal energy to the performance of tea withering. As a source of geothermal fluid, a water heater with a capacity of 9000 Watts and hot water flowed with a pump were used. The HPHE used was constructed of 42 pcs of heat pipes and 181 pcs of the fin. The heat pipe used had a length of 700 mm with an outer diameter of 10 mm, the fluid worked in the heat pipe using water with a filling ratio of 50%.The fin was made of aluminum with a thickness of 0.105 mm with a size of 76 x 345 mm. The results showed that the effectiveness of HPHE varied from 64.825% to 78.363%. The Henderson and Pabis model was the best model to represent the behavior of tea leaves using Zeolite-A, and the Page model for the withering of tea leaves without Zeolite-A. With the addition of Zeolite-A, the speed of tea leaves withering increased by about 18%. In addition to being environmentally friendly, the use of geothermal energy can be an alternative energy substitution for drying tea that uses firewood which is harmful to health because it becomes the source of anthraquinone (AQ) as a cause of cancer in humans.

Zeolite is extensively synthesized for the application in a large variety of catalysis processes such as ion exchange, hydrocarbon cracking, and organic synthesis. In order to satisfy the serious terms of sustainability that denotes to the reduction of costs and chemical waste, kaolinite‐based zeolites were produced from cheap natural resources as against to the conventional process that employs pure sodium silicate and sodium aluminate. This review paper is to highlight the current trends in the synthesis of zeolite. Prior to previous reviews, great concern is focused on the impurities effect on the catalytic performance of kaolinite‐based zeolites. This study reveals that the impact of impurities in a catalytic reaction was in fact, underestimated or neglected. For instance, it was found that Fe ion concentration as small as 60 ppm gives significant catalytic output. Hence, a new practice to report the concentration of impurities in the research publication is suggested. This undoubtedly will generate a better interpretation of the catalytic activity from the zeolite framework.
