Abstract

The aims of this research were to make and test the material transportation device of grains dan legumes(corn, soybean, and green beans) screw type (screw conveyor), to find the effect of screw angle (α) andcommodities to performance of screw conveyor, and to find out the best screw angle (α) and commodity toperformance of screw conveyor for each angular speed those are 40 and 54 rpm. This research has beenconducted on December 2014 until February 2015. This research was conducted in two phases, those arecreating device which conducted in CV WIDODO, Kuripan village, West Teluk Betung sub-distric, BandarLampung and testing was conducted at the Laboratory of Power and Agricultural Machinery, AgriculturalEngineering Department, Faculty of Agriculture, University of Lampung. This research was conducted inthree different screw angles, those are 30°, 45°, dan 60°. Later, these three different screw angles is subjectedto three repetitions and in two different angular speed (rpm), those are 40 rpmand 54 rpm. The results showthat the best working capacity of screw conveyor on the variation of screw angle and commodities for eachangular speed for 40 rpm on soybean and 30° screw angle is about 178,6 g/s, while for 54 rpm on greenbeans and 30° screw angle is about 238 g/s. It can be indicate that speed rotation (rpm) and screw angelaffect significantly on screw conveyor;s working capacity.Keywords : Screw conveyor, screw angel, grains and legumes

Abstract

The objective of this research was to evaluate responses of grand rapid lettuce (Lactuca sativa L.) grown in anindoor hydrophonic system(awick system) under the treatments of some different types of lighting. The researchwas conducted in April to June 2015. The treatment in this reearch consisted of a single factor (types of lighting)with five levels: Sun lighting (N0), 2 tubes of 18Watt fluorescent lamp (N1), 2 sets of 36Watt LED + 1 tube of 150Watt halogenlamp (N2), 2 setsof 36Watt LED+ 2 tubes of18Watt fluorescent lamp (N3), and 150Wattbulb (N4).Each treatment consisted of four plantswhichwere grown in a 60 cmx 60 cmx 120 cmgrowth chambermade ofplywood, except for sun light treated plantswhich were placed inamini greenhouse. Results showed that amongthe plants in the growth chambers, the best vegetative growthwas shown by the lettuce in the treatment of 2 setsof 36Watt LED + 2 tubes of 18Watt fluorescent lamp (N3), However; compared to those plants grown under thesun light, the lettuce inN3 still looked etiolation because light intensitywas not optimal yet.Keywords: Lamp types, lettuce plants, wick systemhydroponic
