The purpose of this research is to know the heat distribution system in three types of fish dryers. The variations of the dryer room were fire-tube type, fire-tube type with bevel, and air-tube type. This study was conducted by simulating airflow and heat transfer that occurred in each dryer room variation by using CFD software. In the simulation, the dryer was heated using an electric heating element with a temperature of 80 Â°C and the results display hot air flow moving in the drying chamber. In the fire-tube type dryer room obtained average temperature of 46.74OC. In the fire-tube type dryer room with the bevel obtained an average temperature of 44.40OC. While the type of air-tube shows average temperature results of 34.31OC. From the simulation, we known that the fire-tube type has the best heat distribution system.

This study studied the best levels of bioethanol from a combination of cassava peel and pineapple peel mixtures with 6 gram yeast mass and 72 hours, 96 hours and 120 hours fermentation time, to determine the optimal fermentation time and find ethanol levels according to SNI. This research was carried out by hydrolysis or cassava peel and pineapple peel using aquades for 30 minute to break the molecule into two parts, then carried out the fermentation process using Saccharomyces Cerevisae (yeast) and the distillation process using a destilator to obtain ethanol for fermentation then tested with a Refractometer to determine whether there is an ethanol level formed from the distillation process. The best sample selected was then tested for ethanol content using the Gas Chromatography tool. The results of this study are known by using the Gas Chromatography tool to determine the ethanol content contained in the distilled sample, the highest ethanol content of each combination. So that the best ethanol yield from a combination of 100% cassava peel - 0% Pineapple Peel with a duration of 120 hours fermentation producing ethanol of 89.81% is still not included in the SNI category.
