Abstract

Abstract The application of ultrasonic on biodiesel processing can increase the reaction rate and improve theconversion of plant oils into biodiesel. Factors affecting the rate of reaction on the application of ultrasonicwaves for biodiesel processing are temperature increasing, acoustic mixing, onset of cavitations andsurface tension on the micro bubble, and the formation of hot spots in the form of instantaneous pressureand high temperature on the molecular scale. The vibrator dipped into the reactants transferred mechanicalenergy which was transformed into heat, cavitations and hot spots. This research was conducted to seethe effect of the volume ratio of reactants and input energy on the rate of conversion of triglycerides intobiodiesel. The results of this study demonstrated a significant effect of the energy input to the conversion oftriglycerides into biodiesel. The greater specific input energy produced the higher conversion and the higherreaction rate. Input energy by using ultrasonic was significantly lower than the use of a mechanical stirrer.

Abstract

ABSTRACT Efficacies in hatchery depend on the ability to control water temperature. The aim of this research is to reduce heat loss in hatchery room, so that the energy requirement for water warming will be more efficient. Two units of flat plate solar collectors were serially installed. On-off controller is used to control a fan which is used for air re-circulation in 6m x 4m x 3m closed room. Experiments were carried out to find effectiveness of solar collector as a controlled warmer unit by perceived both temperature and relative humidity parameters. Initial  experiment results indicate that solar collector as a warmer unit is able to  give mean room temperature with tow standard deviation. The statistical analysis results also indicate that the mean water temperature at the controlled air re-circulation system with circulating water is equal to 27. 6 0C with standard deviation equal to 0.7 0C. Additional 350 Watt of electric water warmer can increase the mean water temperature that is equal to 30.6 0C with standard deviation equal to 0.5 0C  which is an ideal environment for fish hatcher. It concludes that the combination of solar collector and electric water warmer as a controlled warmer unit is able to give  mean water temperature with low standard deviation, so that this system can effectively reduce the use of warming energy cost until 76.85 %. Diterima:  1 Ncpemoer 2006: Disetujui: 20 Nopember 2006
