Thesis ; no. AE-99-17 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering Thesis (M.Eng.) - Asian Institute of Technology, 1999 Drying of jackfruit dodol was studied using an experimental hybrid solar dryer at Mataram, West Nusa Tenggara, Indonesia. The performance of hybrid solar dryer was compared with air oven drying, solar drying and direct sun drying. The performance parameters included the drying efficiency, water removal, drying rate and patterns of energy utilization. The success of the hybrid solar dryer application was evaluated in terms of the quality of the final product, and was followed by economical analysis. The results of this study showed that the hybrid solar dryer had system drying efficiency of 17.0%, a collection efficiency of 35.3% and pick-up efficiency of 26.4%. The placement of jackfruit dodol on different trays affected the moisture removal, and was significantly influenced by the cloud and rain conditions. However, the overall average temperatures in the dryer were not significantly different. Implying that the solar energy contribution still existed. Simple log and modified log models were used successfully to predict jackfruit dodol drying in air oven, hybrid solar dryer and solar dryer. It provided basic information on relative comparison of jackfruit dodol drying rates in the different dryers. The evaluation of products dried by hybrid solar dryer indicated significant differences in terms of texture, taste, and color in comparison to direct sun drying, solar drying and air oven drying. Statistical analysis of the acceptability in terms of color showed that the panelists preferred the brown color more than yellow color. In certain range without mold and non-enzymatic browning effects. The panelists tended to like the hard texture of jackfruit dodol. In contrast, the texture of product from direct sun drying was found softer. Though the texture of hybrid solar dryer was relatively hard compared to other methods, it was inferior compared to air oven dryer treatments. Economic analysis showed that the three drying methods (hybrid solar drying, solar drying, and direct sun drying) were adequate for jackfiuit dodol processing. But when considering higher product quality, It was necessary to develop drying systems for jackfruit dodol processing similar to a hybrid solar dryer used in this study.
