Abstract

The influence of rotation engine speed to coco fiber and coco peat yieldof coconut fruit from Jambi area has been done. The study aims to know the percentage of cocofiber and cocopeat produced based on the influence of rotation engine speed of decomposition machine starting from 225 rpm, 450 rpm, 750 rpm and 900 rpm.  Each round speed will operate for 2 minutes with 500 grams of raw material and use variation 5 and10 decomposing blades. The result show that(1) the rotational speed of the decomposition machine affects the amount of cocofiber and cocopeat produced. The highest percentage of cocofiber and cocopeat is at 450 rpm (2) The number of blades of the decomposition machine against the percentage of cocofiber and cocopeat produced. The highest percentage of cocofiber and cocopeat using 10 blades. (3) The maximum result of cocofiber and cocopeat obtained from engine speed 450 rpm is 28% cocofiber and 50% cocopeat.

Abstract

Rubber plant is one of the potential plants, the production of latex from the rubber plant is used as a raw material for making rubber bands, and the cutting process is required by a rubber band cutting machine. The purpose of the performance analysis of this rubber band cutter is to find out the cut / minute results of this machine and the machine uses a 1.5 HP electric motor with a reducer ratio of 10: 1 and get a 110 Cut / minute result and from the results of data retrieval using a thick cutting knife 5 mm on average this machine can print granules with a thickness of 2 mm. As for this machine, it will be sold at a more economical price and uses a level of electricity consumption that is not wasteful compared to machines that are already on the market.

Abstract

The purpose of this study was to determine the performance of a hybrid dryer by combining the utilization of solar energy (solar dryer) and biomass power sources. Utilization of solar thermal energy sources by maximizing solar heat radiation sources which are absorbed directly into the drying chamber in the form of a transparent house with ventilation holes for fresh air to enter and moist air to exit. This process will produce hot air circulation (convection) in the drying chamber continuously so that the process of evaporation of water from the material being dried is faster. The temperature of the hybrid dryer with a sun source without the test material was 56º C. In the hybrid dryer test with a biomass combustion power source without the test material, the maximum temperature was 46 º C with a stable temperature of 40 º C. In the hybrid dryer test with a solar power source with the material test with a drying rate for 6 hours of drying there was a reduction in the mass of areca nut by 19%. The performance of the hybrid drying machine is better when the temperature is controlled with a setting temperature of 60º C. The average drying rate of areca nut from the hybrid dryer is 1 kg/hour
