Abstract

Abstrak Plastic deformation is metal forming process that resulted in material could not return as the initial condition both in its size and form. Plastic deformation process can be achieved by cold work i.e. metal forming processes below the cristalization temperature of the material. After cold work, the mechanical properties will change in its static, dynamic mechanical properties, and corrosive resistance. The experiment on the rate ofcorrosion was conducted in order to investigate the corrosion properties of the material. In this experiment, the setted up of deformation degree were 5%, 10%, 15%, and 20%, respectively. The material was low carbon steel AISI 3215. After treatment, each of samples was placed in corrosion mediums i.e. water, sea water, and air. The results showed that the average of corrosion rate in sea water increased from 0.0333 mm/year for the specimen with deformation degree 5% to 0.067 mm/year for specimen with deformation degree 20%. The rate of corrosion in water and air was lower than that of sea water.

Abstract

Frontal direction crash has become most serious cause in traffic accident. Based on the fact, this reaserch focused on the passenger movement in a frontal crash. The research was aimed to predict the direction of passenger movement and the benefit of using the seatbelt to decelerate the passenger movement in a frontal crash. The research was conducted by computer simulation by using Delphi 7. The inputs were vehicle velocity (80 km/h), mass of passenger (75 kg), and mass of vehicle (2000 kg). The results showed that in a frontal crash the deceleration of the passenger was smaller than that of the vehicle. The result of simulation showed that the force on passenger was 1.8352 N. If seatbelt tightness 1 N/cm2 was applied, the force on passenger decreased 468.56 N. In this case, the passenger still had relative velocity to the vehicle vrf = 1.75728 m/s and the force on passenger was 249.46 N. The seatbelt had important function to decelerate the passenger movement to the same deceleration of the vehicle during the frontal crash.

And this can be carried out by continuous regulation of damper and elevator using neuro fuzzy control. Theparameters used here are the speed input of the vehicle, steer turning angle, the body's vibration and slanting angle as well asbody's pitching. It is hoped that the damper ratio can be low (good) for any field and can arouse down-roll effect on the bodywhen the vehicle is turning. This experiment used simulation method with plant data for suspension using Proportional IntegralDifferential (PID) control and the one using continuous fuzzy control. The suspension performance from these two controls wasthen analyzed using Bode and Niquist diagrams. The result shows that the body moving response using the fuzzy control canreach –2 to 2, the highest and close to 0, the lowest, which means that the response is low. While the body moving responseusing PID control can reach –3 to 3, the highest and –2 to 2, the lowest. It can be concluded that the moving body responseusing fuzzy control is better than the one using PID control. It is suggested that further experiment using different brand namecar be conducted.Keywords: Continuous fuzzy control, Damping ratio, Up-roll, Down roll, Niquist simulation.

Abstract

The Pitik Jaya Women Farmers Group (KWT) is a business group located in Baluk village which is classified as a home business or home industry. This business group produces several types of products including; shredded eggs, flavored salted peanuts and others. In running its business, KWT faces a number of problems, especially for the production of the flavored salted peanuts. This problem is caused by the process of roasting peanuts using a rolling machine which is relatively simple with a limited capacity made from steel plates and is easily corroded and the spices are still stirred manually so it is uneven. Another problem is related to the high cost of LPG fuel used to heat the roaster. Based on this situation and to overcome these problems, the community service team designed and manufactured a roasting machine with biogas fuel. The field service activity (KWT Pitik Jaya) was carried out on August 22, 2021 in the form of an introduction and demonstration of a biogas-fired roasting machine. Next, on August 29, 2021, a safety demonstration was held and the official handover of the machine was attended by members of the Pitik Jaya KWT, the dedication team, Engineering students from the Udayana University Mechanical Engineering Study Program and Baluk village officials. The use of this biogas-fired roasting machine plays a very important role in increasing the production of flavored salted peanuts which reaches 320% or more than three times, as well as fuel cost efficiency reaching 90%, because it no longer uses LPG. Keywords : roasting machine, salted peanuts, biogas, increased production.
