This study investigates three different types of power plant include a trilateral cycle (TLC) subcritical organic Rankine cycle (ORC) and supercritical ORC power plant driven by geothermal heat source with mass flow rate 1 kg/s and temperature of 100๐C 110๐C and 120๐C. with 27 substances were examined as the working fluid of the power plant. While the net power output of 4.78 kW and 7.74 kW is obtained from the subcritical ORC with RC318 as its working fluid when the heat source temperature are at 100๐C and 110๐C respectively. Meanwhile the net power output of 11.85 kW is obtained from the subcritical ORC with R227ea as its working fluid when the heat source temperature is at 120๐C. The net power output of 5.64 kW and 9.16 kW are obtained from the supercritical ORC with R218 as its working fluid when the heat source temperature are at 100๐C and 110๐C respectively. Meanwhile the net power output of 12.88 kW is obtained from the supercritical ORC with R143a as its working fluid when the heat source temperature is at 120๐C. Furthermore the net power output of 7.96 kW 12.27 kW and 17.38 kW are obtained from the TLC plant with heptane as its working fluid when the heat source temperature are at 100๐C 110๐C and 120๐C respectively.

The development product of dried pickled passion fruit peel aimed to study appropriate production process of dried pickled passion fruit peel to study the preservation and examine the acceptance from the customers. The result showed that the appropriate way to produce dried pickled passion fruit peel was the 30% 40% and 50% of intensity in syrup. With the intensity of syrup started from 30% the appearance color and smell of final product got highest average score. Therefore the production should be slow pickled with 30% of syrup intensity. In terms of preservation there was no microorganism over Thai industrial standard institute of fruits and vegetables 161/2015. Finally most of the customers accepted this product
