Abstract

Forest fires are one that needs attention in Indonesia. Due to spent a lot of money to solve this problem. One of the tools to solve this problem is fire fighter, so in case is need to make the fixture can manufacture the fire fighter kit. In this study, we propose the fixture that can be produce the kit. It call fixture fire fighter kit. Autodesk inventor is applied in the simulation design and also it is considering with the ergonomic for the worker especially the Indonesian male. Finally, this tool can be resistant with load 50 kg, the deflection is 0.831 mm, and the maximum von misses stress is 34.12 MPa.

Abstract

The scarcity of fuel oil, especially the gasoline type, is now a national problem that needs to be solved. This is caused by the rapid growth of industry and transportation. On the other hand, the problem of handling wet garbage has not been maximal, causing pollution that can disrupt health. The impact of this problem is felt also in the use of household-scale generators that operate using gasoline fuel. This study aims to convert gasoline to methane gas in the operation of a 3500 Watt Generator (Electric Generator Set). Methane gas (CH4) is obtained from the gasification process of wet waste. The method used for the AFR (Air-Fuel Ratio) regulator is the use of vacuum valve components. The use of this method cannot be separated from the easy aspects of the maintenance/repair, easy to make and cheap price. The target to be achieved in this research is to get performance data of generators operated with Methane gas fuel. The generator which is used as a research object is a generator household scale with a maximum power of 3500 Watt. Results variables to be observed among other: engine efficiency as well as optimum engine AFR generator. Furthermore, the data is compared with the data generated generator that uses gasoline fuel. This research is an experimental study, starting with the design of the vacuum valve component, followed by the installation of the component on the generator machine and ending with a machine test. The experimental data on the generator with the nominal power of 3500 Watt is: Operated by Gasoline, the optimum power, Popt is 3750 Watt, Max. efficiency, ηmax is 62.2%; AFRopt is 6.7, then operated by methane gas, optimum. power, Popt is 3270 Watt, Max efficiency, ηmax is 66,1%, AFRopt is 7,2. So, gas methane can be used to replace gasoline to operate 3500 Watt generator.
