Abstract

Biogas is gas produced by bacteria when organic matter undergoes a fermentation process under anaerobic conditions, and will produce methane gas which is temporarily stored in a container called a biogas bag. The biogas bag needs to be controlled to ensure the biogas bag remains safe. The control system is in the form of a two-position control because it has the advantage of being cheap and simple, besides that the solenoid valve as an actuator has a non-linear output property. To detect the capacity of the biogas bag, the HCSR-04 proximity sensor is used as feedback on the set point value that is set, which is 50 cm for the maximum set point and 30 cm for the minimum set point. The results obtained by the proximity sensor is able to read the distance with an accuracy of 5.8% and the On-Off control has a response of 0.25 seconds.

Abstract

Strength, toughness, machinability and damping capacity are properties of compacted graphite iron thatdistinguish the properties between flake graphite cast iron and spheroidal cast iron. The formation of compactedgraphite can be set to achieve the required specification. The formation of compacted graphite is started fromspheroidal to compacted cast iron. The residual magnesium after magnesium treatment and the solidification ratehave a significant role in the formation of compacted graphite. The high content of residual magnesium canobstruct the graphite plane to grow during the transformation from spheroidal to compacted shape. In addition,the cooling rate of the casting can be controlled by varying the casting thickness. The compacted graphite in thecast iron are characterized according to shape, size ai`nd distribution. The optimum compacted graphite in thecast iron that can be produced has 30 mm of casting thickness with 0.017 % of residual magnesium.

Abstract

The natural gas potential in Indonesia can be used to support the renewability of alternative fuels for motorcycles.LPG (Liquefied Petroleum Gas) is one of the Gas Fuel products that can be used as fuel to replace the use of OilFuel. Therefore, an energy conversion tool is needed to utilize LPG as a motorcycle energy source. The purposeof this research is to design and manufacture a gas motor converter kit. This converter kit has three technologies,such as 1) a fuel distribution system that uses a manual fuel faucet so that the fuel distribution process is better,2) there is a solenoid valve that functions to cut off gas flow when the vehicle stop without removing the regulatoron the fuel tube, and 3) the position of the gas fuel tube is under the motorcycle seat so that it is safer. The researchmethod using VDI2221 (Verein Deutcher Ingenieure). The research result is the creation of converter kits thatare made through the design process, turning process, milling process, welding process, and assembling process.The research conclusion obtained is that the converter kits that have been made can be implemented on 100ccmotorcycles, and no leaks or defects were found in the converter kits, so the tool can be used properly on 100ccmotorcycles.

Abstract

The characteristic of fluid flow and heat transfer on a circular cylinder with particular pattern is frequently used in various branches of modern technology today. The amount of heat transfer when fluid cureent passes through circular cylinder is expressed by Nusselt number parameter, eiter local Nusselt number (NuФ) or average Nusselt number. Forced convection heat transfer on the circular cylinder with a staggered-type of using Reynolds number (ReD) varied as the value of 80, 200, 5000 while the tranverse pitch (2D, 2D). The fluid inlet temperature entering shell is 350 oK and the tube temperature is 300 oK, which is modeled whith Gambit 2.4.6 and simulated using Fluent 6.3.26 whith turbulent model k- SST 2D steady-flow to obtain data related to the velocity profile and temperature distribution. From the simulation results obtained visualization contour of velocity, temperature and Nusselt number distribution. The smallest Nusselt value is at ReD 80 then ReD 200 and the highest is at ReD 5000.
