Abstract

Shovel is one of the important parts in the clay grinding machine component, where this component serves to direct the material that is milled in the mill between the roller and roller bearings. With the high rate of replacement of this shovel material due to wear will have an impact on the decline in engine productivity due to lost working hours. Shovel material is made from Hardox 400 material where the value of BHN material hardness: 370 - 430, the value of material hardness is very influential in determining the age of the shovel, but still calculated from the side of the collision load that occurs during grinding. From the results of testing both macro testing and micro testing it is known that the value of material hardness (Hardness test) is not in accordance with the specifications of the material which is around 37% below the specification value. And from the SEM test results it can also be observed that there has been a significant change in the grain structure of the matrial surface and scouring on the shovel samples that have been used.

Abstract

The effect of machine movement will generate mechanical vibrations and these mechanical vibrations will cause vibration propagation in the air and this will create noise. This noise itself in situations that exceed the threshold will cause discomfort to driver and can have an impact on health. In this research, it was obtained by increasing the engine speed starting from 1000 rpm and increasing at intervals of 200 rpm up to the maximum speed at the position of 2800 rpm. Found that the noise level was obtained from the lowest position of 48 dB which then increased at intervals of 1 - 2 dB up to the maximum position with a noise level of 62 dB. From these two measuring parameters, the level of correlation coefficient between the increase in engine speed and the increase in noise level, rxy = 0.9220, found that a strong positive correlation between these two measuring parameters. With the noise level in the car driving room ranging from 48 – 62 dB, referring to the Minister of Environment (LHK) Regulation No. 7/2009 concerning motor vehicle noise thresholds, the maximum quality standard set is 77 decible (dB) for passenger cars, so the level The noise that arises in the driver's cabin of the car is still in a safe condition for the driver and passengers in the car

Abstract

Buntu Bedimbar Village is a village located on Jalan Batang Kuis Pasar VIII, Tanjung Morawa District, Deli Serdang Regency, North Sumatra Province. The location of this village is a rural area where there are still many fields or rice fields that are used for farming to meet living needs. The urgency of this community service is related to partner problems, namely the absence of tools or technology that can assist in the process of peeling, shelling and chopping corn cobs, all work activities are carried out manually which in the end prolongs the work process time and has an impact on obtaining final results that are not optimal. The solution is to create a mechanical system of tools/machines for peeling, shelling and chopping corn cobs, to speed up the work process of corn farmers. The aim of this community service is to help solve problems faced by partners, namely by applying appropriate technology in the form of a multifunctional machine combining shellers, shellers and corn cob choppers using mechanical power that has been assembled in the mechanization of one work system. The implementation method is by coming directly to the location. partners, discussions look for partners' problems and then provide a solution, namely by making a multifunctional tool with a combination of mechanical system peeler, sheller and corn chopper. This tool works once to produce 3 outputs in the form of (corn peeler, corn sheller and corn cob chopper). The results of community service activities that have been carried out to date show that the community can accept this activity well, the tools provided can function and can help ease the work of corn farmers, especially during the harvest season.

Abstract

This study aims to evaluate the characteristics of the dynamic load that occurs on the beam clamped at one end and the other end in a free condition. At one end of the rod a load is given so that it will cause a larger dynamic load on the rod. The method used to analyze the dynamics of this cantilever rod structure uses the Finite Element Method. The cantilever rod will be divided into four elements and has 10 nodal points, vibrating nodes are occured at node 3 until node 10. By using stiffness and mass matrix analysis, found that the largest deflection value is obtained at node 9 with a deflection value of 0.2555 m and the largest angular rotation occurs at node number 10, which is 0.0958 rad. By assuming the weight of the cantilever bar is ignored, the reaction at the clamped rod support is obtained equal to the magnitude of the load given at node 9 in the opposite direction to keep the rod prevent from falling, which is -100 N. The farer distance of nodal point from the end of the bar that is given the load then the smaller the deflection that occurs, including the angular rotation will also be smaller. The selection of beam materials, beam dimensions, beam installation methods and determination of the external load greatly determine the safety factor of the cantilever beam construction.
