Abstract

This research is the development of a generator that can be on/off automatically based on the existence of commercial power. Genset used in the study is the generator of household scale premium gasoline. In particular, this study aims to make switching system for two generators with timer settings to prevent loss of power. Testing the performance of the system is made to ensure that the system is functioning properly. Specification design tool created an amalgamation of two generators which can perform on/off according to a predetermined time. After the generator 1 operating for 4 hours, then automatically generator set 2 will live. About 10 seconds since the first 2 live generator, the generator 1 is still in operation, then the load will be transferred to the generator 2. With this delay system, then nothing happens lost power. This mechanism will be repeated after 4 hours of generator 2 operates. With this system, the availability of electrical power would continue as needed. Keywords: automatic transfer switch, generator set

Abstract

Until recently, generator available in the market, generally gasoline or LPG. Conversion of gasoline to fuel bio-ethanol requires some adjustments.The research conducted was  a further development of research Nurjan Didik Purwanto in 2011. The research was focused on adjustment of airand fuel ratio after the fuel in the generator set was replaced with bioethanol. Bioethanol has a higher octane rating than gasoline, but it has a lower calorific value than petrol. With this condition, it is necessary to attempt to increase the ratio of air and fuel to be more "fat " to regulate the entry of air through the carburetor. Settings ratio of fuel and air is done by adjusting the carburetor choke openings. This setting restores the stability of the engine, the same as using premium gasoline.This study primarily aims to expand the use of renewable energy, especially for the implementation of electric power for households.The results of this research  has been successfully realized by using a Timer Switch AC, 12 Volt DC timer switch, solenoid valve (solenoid valve), and actuators. Aperture choke1/3 on the use of bio-ethanol fuel produces almost simillar to  the engine speed compare to it when  using gasoline. Fuel consumption of bioethanol is 40% more than the use of  gasoline. Keywords: choke, gasoline, bio ethanol

Abstract

The fish feed spreader machine is a feeding tool that is made to facilitate fish breeders in feeding fish. The fish feed spreader is specially programmed to provide fish feed according to the schedule and the desired dose. The purpose of making this tool is to design a fish feed spreader machine based on the logic controller programmale, and to test the performance of the designed fish feed spreader machine. The results showed that the average feed expenditure was 2.66 kg for a duration of 40 seconds. Then for the farthest throw of feed is 7.5 meters, while for throw of feed that is evenly distributed it has a distance of 5 meters with a spread width of 5.85 meters, and the angle of spread of feed is 90º.

Abstract

The process of draining oil is one of the processes that can affect the oil content of the frying or chips. The oil that is left in a lot of fried food or chips when stored for a long time will cause a rancid smell. Meanwhile, if consumed directly, it will affect the health of consumers because of high cholesterol levels. Most people do not know the consequences that occur if they consume excess oil. People who already know cannot do anything because the oil draining machines on the market are still quite expensive and their working capacity is limited. In the previous research, a draining machine with a tube system with a diameter of 40 cm and a height of 22.2 cm was made with an rpm of 517. Within 5 minutes this system reduce oil content from 27% to 24,65% . The data shown in strightline gaphic trend that mean the reduction oil conten is not optimal yet . For this reason, this research will be redesigned by extending the spinner axis and adding the bearings to 2 units, it is hoped that this addition will stabilize the spinner rotation, the rotation can be increased and the ability to reduce oil content increases. extending the drain axis and increasing the position of the bearing to 2, the draining machine has been able to function properly until 967 rpm rotation, from the test results for draining the cassava chip oil, within 5 minutes, the slicer with a rotation of 598 rpm can reduce 2.29%, 727 rpm 2.93%, and 967 rpm 4.27% rotation.
