Abstract

FDM is an AM method that is currently being developed due to the flexibility of the object geometry that can be formed. This study aims to design the frame and drive of the XZ Head type FDM engine. Stress simulation was carried out to determine the safety factor in the frameXZ design. Lead screw parameters in the form of torque, shear stress, axial stress, and critical load were calculated to determine the torque requirement of the driving motor. The value of the linear axis of the stepper motor was calibrated to determine the dimensions of the printed output. Based on the simulation, the dynamic and static stresses on the XZ frame were 1.9 MPa and 2 MPa. The yield strength was 55 MPa with a safety factor of 28. The results of the calculation of the lead screw torque (TR) and (TL) were 18.27 N.mm and 6.60 N.mm. The calculated nominal shear stress of the screw () was 0.43 N/mm2, the axial loading stress () was -0.62 N/mm2, and the critical load (Wcr) was 9986.41 N. The difference in dimensions of the measurement results in the X and Z planes was 0.22 and 0.17 mm larger than the target dimensions of 20 mm.

Abstract

Thickness measurement using an ultrasonic sensor is a type of non-destructive test (NDT) that is commonly used in various industries. Measurement of thickness (thickness) on steel blocks, aluminum blocks and steel plates using an ultrasonic thickness gauge. The method used is the contact testing method which is then compared with manual measurements. Based on data analysis from the measurement results, it was found that the thickness with the highest percent error was in the Steel S3 sample, namely 93.87%. Meanwhile, the thickness measurement with the lowest percent error in the Steel plate sample was 0%. Meanwhile, for measuring the dimensions of artificial corrosion defects, the smallest error percentage obtained was 0% for several dimensions, with the average measurement error obtained being 22.82%. The profile shape of the detected artificial corrosion defects is exactly the same as the reference profile. So, measuring the thickness of steel blocks, aluminum blocks and steel plates as well as measuring artificial corrosion defects located in steel plates can be detected well and the measuring results can be trusted.

Abstract

The utilization of wind energy as a power plant still needs to be improved by looking at the turbine performance, which is not always the same in different regional conditions. This study aims to determine the effect of the blade angle of the turbine on the tip speed ratio (TSR) and power coefficient (CP) by using a Q-Blade simulation. Q-Blade software can predict the value of the power generated at the blade rotation by comparing the CP and TSR values. The type of airfoil NACA 4412, taper blade, blade's numbers (4), blade radius (0.3 m), wind speed ± 3.6 m/s were fixed variables in this study. The simulation generated a graph of the relationship between CP and TSR changed and a simulation image of the load distribution ensued in the blade geometry. The blade angle of 30 at the TSR number 5 produced the highest CP values, which was ±0.4. The low loading value in the axis/rotor region, at a variation of the blade angle of 30, balances the centrifugal force on the rotating fluid. The centrifugal force produces thrust on the turbine so that the blade rotates with a high CP value in that area.

Abstract

Yutuk, which is also known as undur - undur laut, is a typical souvenir from Widarapayung Wetan beach. The handling of yutuk before consumption by community groups processing yutuk is still in a simple way by soaking it in a bucket or tub. Depuration of yutuk or shellfish makes the dirt contained in the organs of the body come out and can reduce the heavy metal content contained therein. This Community Service activity aims to increase the education of yutuk processing groups to use the depuration method with a special yutuk tub with a recirculation system that uses natural filters such as ginger coral, zeolite and activated charcoal. The Community Service activity stage begins with interviews and field observations and then continues with a Focus Group Discussion (FGD) and then implements a yutuk depuration tub for the yutuk processing group in Widarapayung Wetan village. Through Community Service activity, the yutuk processing community groups are equipped with good and correct depuration techniques so that they can be achieved properly and the community can consume them safely and comfortably.
