Abstract

Acetone-butanol-ethanol (ABE) is a preferred alternative energy for SI engines. This research uses an experimental method with an automatic SI engine, RON-90 fuel mixed with ABE1 (12:8:1)v/v, ABE2 (15:10:1)v/v and ABE3 (1i8:12:1) v/v. Engine speed is 4000-10000rpm, and compression ratio is 11.6:1. Emission and engine performance testing used EPSG4-Gas analyzer and Dynotest-chassis type 50L-BRT. This research aims to explore the mixture of RON-90 and ABE to optimize performance and exhaust emissions. This research shows that torque increases by an average of 14.7% at an engine speed of 6000rpm. Power increased significantly with an average value of 9.5% at an engine speed of 8000rpm, MEP increased by 0.5%, and thermal efficiency increased by 7%. SFC experienced a fairly optimal decrease of 15.6% on average. The exhaust gas emissions produced are CO and HC. The reduction in CO and HC occurred in the ABE3 variant with values of 8.2% and 1.6%, respectively.

Abstract

The Garbage is residual material that has been disposed of and is no longer used, so that waste is considered something disgusting by some people. Garbage has two types, namely organic waste and inorganic waste. Therefore, good waste management is needed so that every day waste does not accumulate and does not disturb the surrounding environment. The purpose of this research is to design a garbage chopper that is useful for chopping organic and inorganic waste to help the waste processing process so that there is no buildup every day. The design of this chopping machine is made multi-functional that can chop organic or inorganic types of waste, designed according to the wishes of consumers or users and made ergonomically. The method used in this research is the Quality Function Deployment (QFD) method and the user's body Anthropometry so that the dimensions of the machine are in accordance with the user which causes the design to be ergonomic. The results of the research are to produce a design of organic and inorganic waste chopping machines that have specifications such as machines using mild steel so that they are easy to move, durable, speed up the chopping process because there is a speed setting, automatic. In addition, the machine has ergonomic dimensions from the results of the machine user's body measurements using the anthropometric method.
