Abstract

Corrosion occurs in almost all metals. Even corrosion-resistant metals are corroded, but their corrosion rate is different from ordinary or non-corrosion resistant metals. This study examines the corrosion rate that occurs in stainless steel that is stainless steel. Stainless steel contains high enough chromium levels that can reduce the rate of corrosion that occurs. The metal material to be studied is the AISI 420 steel, which belongs to the Martensitic Stainless Steel class. This study examined the effect of heat treatment on corrosion rate and hardness level of AISI 420 steel. The heat treatment carried out was Quenching at 1020oC with a holding time of 60minutes with an oil cooling medium. After quenching the subsequent heat treatment is tempering with temperature variations of temperature 200oC and 300oC with a resistance time of 45 minutes and air cooling media. The results of this study showed that the base material specimens had the highest corrosion rate of 0.569 mm/y. The lowest corrosion rate is in specimens with quenching process with a value of 0.267 mm/y. The highest Vickers hardness values were found in specimens with quenching process with a value of 551 kg/mm2. The lowest hardness value is in the specimen with tempering process at 300oC with 405 kg/mm2.

Abstract

Organic wastes has potential as a renewable energy resource. The waste could be converted as a gaseous fuel through gasification method. The objective of this reserach was to study the performance of gasification of various organic waste using fixed bed updraft gasifier especially in term of production of heat and stability of gas production. The raw material that used are rice husk, sawdust pellet, and wood branch. The stabilization of gas production was measurdd based on the time interval of gas could be burnt. The result shows that the kind of biomass has influenced the heating rate and stability of gas production. Sawdust pellet have the biggest burning stabilisation, that is 45 minute of burning time, compare to rice husk that have 15 minute burning time, and wood branch that have 30 minutes burning time. The main problem of gasification of organic waste was less stabilization of gas production due to low material compaction and uncontinuous mass flow.

Abstract

The composite is a combination of two or more materials to produce a new material with unique properties compared to the nature of the base material prior to mixing and surface bonding occurs between each constituent material. The purpose of this research is to know the influence of waste material composition from plant fiber, that is young coconut fiber, banana stem, and calendar waste paper to bending strength on composite board by using Epoxy resin wood type. The process of printing the composite board is done in the Laboratory of Integrated Mechanical Engineering University Proklamasi 45 Yogyakarta. The three raw materials that have been crushed and dried, mixed with the breaking time of each 5" and 10" with their respective ingredients composition, namely Young Coconut Fiber: Banana Stem Fiber: Calendar Waste Paper =25:25:50; 25:50:25; 50:25:25 (%). Each treatment was repeated 3 times. Observation was done by calculating raw material composition and time of destruction process against bending strength of composite board which resulted very significant effect on water content, fracture, and flexibility of composite board. Bending strength testing is performed using a robust Universal Testing Machine (UTM). The result of this research produced the most optimum material composition of bending strength into composite board, ie composition III with the duration of destruction for 5", that is the average MoE value of 17.069,76 kg/cm² and the average value of MoR is 83,78 kg/cm². From this research is expected to get new engineering technique from agriculture waste become composite board with economic value.

Abstract

Oxy-acetylene welding is widely used in small workshops for car body repair, automobile and motorcycle exhaust, and other improvements using a maximum temperature of 3000oC that can not be done through another process. The purpose of this study was to analyze the effect of torque oxyacetylene flame carburizing on the physical-mechanical properties of low carbon steel plate welding joints. The method employed by using a low carbon steel plate 2 (two) pairs in a butt weld immension of 300 mm x 75 mm x 1 mm. After welding with oxy-acetylene in torch carburizing flame, the specimens were examined through physical observation including microstructure and echanical properties. Micro hardness vickers (VHN) was used to evaluate the harness and tensile properties was determine using the universal testing machine. In the microstructure testing, there is a pearlite and ferrite whose become different dimensions as it is affected by the heat and air pressure of the weld. The result of tensile strength specimen A 174,6 N/mm2 and specimen B 157,65 N/mm2. While the vickers test obtained the highest hardness that is 152.5 VHN in the welding area.

Abstract

Soybean miller machine is an innovative machine that makes it easy for tempeh producers.This machine uses a threaded shaft (screw), making it easier for tempeh producers in producing more higienic tempeh easy and fast threaded shaft (screw) is made of aluminium alloy metal. This research study is intended it find the ideal alloy as material for the manufacture of threaded shaft (screw). This research study used a mixture of 40% aluminium profil and 60% of used pistons with 2.5% Ti-B (Titanium-Baron) as a smooth refiner. The mold used is a metal mold (die casting) with a mold temperature heating of 200oC. The test to know the mechanical properties of the aluminium alloy is tensile and hardness test. Based on the test results of the tes tis that the specimen with heating temperature of 200oC producers a maximum tensile stress of 148.08 MPa, while for vickers hardness testing yields an average hardness of 95.1 Kg/mm2. The results of the experiments using heating temperature of 200oC and 400oC obtained microstructure on aluminium alloy casting specimens with 2.5% Ti-B addition, the most evently formed phase ini all specimens was Aluminium (Al) phase.Universitas Muhammadiyah Yogyakarta
