Abstract

Limited availability of fossil energy requires us to find for alternative energy to meet our needs. Solar thermal collector with thermosifon system is one of environmentally friendly alternative energy. The thermosifon system is a natural pump which work based on density difference between cool water and hot water, so that no electric pump is needed. The purpose of this research was to create a mean of collecting solar thermal energy with thermosifon system. The research steps consist of designing, manufacturing, and testing. Thermal collector was made with dimension of 1,5 m long, 1,0 m wide and 1,0 m high, with storage tank capacity of 20 lt.  Collector testing was conducted by putting the equipment at an open space from a clock 08:00 – 16:00. It was found that the highest efficiency of solar collector (11,2 %) occurred on July 11, 2012 with an average solar intensity of 756 W/m2, where as the lowest efficiency  (8,8 %) occurred on July 7, 2012, with the average solar intensity 479 W/m2. The highest average temperature of the storage tank was 44,7 ºC on July 13, 2012 while the lowest average temperature was 35,3 ºC on July 12, 2012.

Abstract

Development in science and technology today has been able to produce instant nutritious foods, such as imitation rice.  The application of conventional technologies in the granulation process causes minimal quantity and quality of the imitation rice with corn feedstock generated.  The purpose of this research was to design and to test its performance. This research was conducted at the Laboratory of Agricultural Engineering, Agricultural Engineering Department, University of Lampung.  This research procedures included several stage: design, assembly, testing, observation and data analysis.  The corn rice granulator machine is designed to the specifications of length 140 cm, width 75 cm, and height 170 cm and comes also with other components, such as hopper,  sprayer, sweeper, corn rice container, electric motors, gearboxes, pillow block, and couple units.  Some of component settings in the testing of this machine: the slope of granulator pan at 35°, discharge of hopper 0,2 kg/sec, discharge of water sprayer 0,54 mℓ/sec, speed of granulator pan rotation 28 RPM, and the clearance between corn rice container and granulator pan by 5 cm.  The results showed that, this granulator machine had production capacity of wet corn rice up to 10,92 kg/hour, and efficiency of granulation up to 78,18%, for the raw material with composition 75% corn flour and 25% tapioca flour. Keywords: Granulator Machine, Imitation Rice, Corn.
