Abstract

The objective of this research is to find out the effect of preheat on mechanical properties of the metal inert gas welding (MIG) on low carbon steel. The welding method uses a MIG welding on a low carbon steel strip plate specimen, in the V angle of 60°, using ER70S-6 electrode wire and CO2 for protection, the variable of this research is a preheat temperature of 100 oC, 200 oC, 300 oC and non-preheat. The test results showed that the highest Vickers hardness value is owned by the preheat 200 oC temperature with Vickers hardness value of 206.674 kg/mm2, the tensile test specimens with preheat 200 oC temperature variations have the greatest tensile strength is the average of 54.87 Kgf/mm2, the value of the highest impact energy on preheat 100 oC of  98.399 Joules.

Abstract

Diesel Motor is a type of piston combustion motor commonly called Ignition Compression Engine Combustion Engine. The use of coconut fiber chopper machines using diesel drive engines in the market has not been able to increase consumer comfort and efficiency. Because of this issue that emits CO2 and NOx also causes air pollution and noise emissions, it tends to be relatively large and also requires intensive care that requires a lot of space and costs. This will renew the surrounding environment and allow user comfort and efficiency when running the machine. Therefore, it is necessary to have an efficient and optimal coconut fiber chopping machine by reducing noise so that it is not noisy and pollution-free. The coconut fiber enumerator with an electric motor drive is an enumerator of coconut fibers with an electric motor as a solution for making household products and agricultural fertilizers to increase comfort and efficiency for consumers so as to increase economic value in the community. This research method begins with making a tool consisting of a study of literature, measuring each component of the tool consisting of a frame, eye drive, motor drive, filter and pulley and designing the design model. Trial on a no-load blade shaft rotation of 450 rpm. At the time of enumeration, the shaft rotation is reduced to around 350-400 rpm and the linear velocity of the V-Belt is 3.9 m / s. From the coconut fiber chopper with an electric motor drive it causes low vibration, does not cause pollution nor is it efficient.

Abstract

One of the abundant energy source in Indonesia is organic waste in the form of leafs and branches which is widely avalilable in homeyard. It can be utilized as alternative energy source by gasification process. The objective of the study was to know the influence of raw material and AFR to the characteristic of organic waste gasification process. The raw material used were leafs and branches of melinjo (gnetum gnemon) which obtained from homeyard of inhabitant in Sidomoyo village, Godean sub-district, Sleman Regency, Indonesia. Before being gasified, it was prepared for proximate analysis in laboratorium. The gasification begins by feeding the raw material to the reactor with variation of 100% leaf, 100% branch, and 50%-50% leaf and branch. The gasification process was occured in reactor for one hour, and syn gas which produced has been analized to know the composition of it. Result shows that raw material have influenced the characteristic of gasification process. The highest heating rate was occured for gasification process of 100% leaf and AFR 0.5, which it gas has burned after 25 minuted process in oxidation temperature of 650 0C, reduction temperature of 350 0C, and pyrolysis temperature of 240 0C.

Abstract

Cocoa waste can still be used as something useful such as compost. The objective of this work is to make an organic waste crusher machine from cocoa waste. The method was the determination of systematic crushing, functional design, draw the crusher, making a prototype of the crusher machine, and performing functional test of the crusher. The crusher machine has been designed and provided. Functional tests conducted indicate that the machine can chop cocoa waste so that it can be further processed as compost.

Abstract

The goal of this research was to find out the aerodynamic body design of Mataram Proto. Using Solidwork 2015 for modeling the body and Ansys 2015 for numerical simulation were the main tools of this research. The body was drawn with scale 1: 1 and then imported into Ansys 2015 for meshing. The unstructured meshes were used in this research. After those, using Ansys 2015, the numerical simulation was conducted with viscous model k - e with realizable type. The result of this research was the average drag coefficient of the original Mataram Proto body was 0,17 and its average lift coefficient was 0.17. For the modification Mataram Proto body, the average drag coefficient was 0.06 and 0.13 for average lift coefficient. These proved that the modification Mataran Proto body was more aerodynamic.
