The framework of the peanut shelling machine functions as a supporting structure for the components of the peanut shelling machine, namely the top funnel, funnel retaining frame, the lid on the peeler shaft, pulley, sieve shaft, sieve, engine body. Frame material is mild steel equal leg angles size 45 x 45 x 5, yield strength is 3,002E + 04 psi and tensile strength is 5.004E + 04 psi. Skeletal strength analysis was carried out using the autodesk inventor professional 2015 software. The engine frame was given axial loading of 500 N, 600 N, 700 N, 800 N, 900 N, and 1000 N. The analysis results of the maximum stress occur at 1000 N loading, amount to 16.85 Mpy, and the maximum deformation occurs at 1000 N loading, amounting to 0.07727 mm.
Aluminum alloy is one of the most non-ferrous metals used in the field of engineering and construction due to its mild nature and resistance to corrosion, while specifically for the A7075 has been widely used in the industrial world and aircraft construction. Cast temperature is one of the many variables found in the casting process. This variable is important because if the pouring temperature is too low then the cavity in the mold will not be fully filled where the inlet of the mold will freeze first, and if the pouring temperature is too high, this will cause shrinkage and loss of accuracy in the dimensions of the castings. The purpose of this research was to compare the aluminum smelting process and the aluminum pouring process in molds made of sand. From this research, the results obtained by increasing the temperature of casting on 7075 aluminum alloy casting. In this study increase the hardness of castings at a pour temperature of 7500 C in sample 1 of 78.4 HB, sample 2 is 79 HB and sample 3 is 76 HB then hardness decreases at 7700 C pouring temperature which is in sample 1 equal to 55.6 HB, sample 2 was 62 HB and sample 3 was 60.6 HB. Tensile strength tends to decrease with the highest increase in pouring temperature of 198 N/mm2 at pour temperature of 7150 C and at the lowest 150 N/mm2 at 7700 C.
= -0,313; p = 0,000 (p<0,01). The relation between conformity and drinking behavior is positive significa with r xy = 0,397 ; p= 0,000 (p<0,01). This is mean tha all hypothesis are proven or accepted.The final conclusion of this study is there is significan relationship between self esteem and conformity with drinking behavior among teenage at kudus.
Motorbikes need a swing arm or swing arm to connect the rear wheel to the frame. Static loading is important in planning the main motorbike so that it can run safely. Swing Arm is the main structural part of a motorcycle chassis that serves to hold the rear wheels for driving and as a shock breaker support. The swing-arm is free to follow the road contours and vehicle loads as long as the motorbike moves. This study aims to determine the condition of the motorcycle swing arm static type twin-shock suspension. This type is chosen because it is most widely used by consumers. This research was carried out by making 3D models of swing arms made from carbon steel models. Analysis of static loading on the swing arm structure was simulated using software based on the finite element method so that the value of von stresses and displacement was obtained. The results of the analysis concluded that the swing arm has good characteristics because the maximum von mises voltage of 43.55 MPa is smaller than the total thickness of 350.0 MPa, and the maximum deformation is 0.003923 mm.
Merauke Regency is the largest regency in Papua with the highest fuel consumption by regency/city in Papua Province. The high fuel consumption is proportional to the emissions produced, so research on emissions absorbing media is needed to reduce emissions. Active charcoal has the ability to adsorption of emissions, one of the raw materials is plants. Bus wood (eucalyptus) which grows a lot in Merauke can be used as raw material for activated charcoal which is used as an absorber of emissions. Research with the title “application of eucalyptus charcoal as emission adsorbent to reduce vehicle exhaust emissions” processes wood logs into emission adsorbents, through carbonation and activation processes, then activated charcoal is applied to vehicle vehicles and subsequent emission tests, to determine emission reduction capabilities. Based on the results of emission tests, the use of activated charcoal as an emission adsorber can reduce emissions. 0.07% CO emissions decreased to 0.01%, HC emissions 84 ppm, decreased to 39 ppm, and 14.7% CO2 decreased 4.4%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
