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 Community Service (PKM) activity carried out in Banjarwaru Village aims to empower the community through structured and effective waste management. The partner in this program, namely BUMDes "Banjarwaru Sejahtera," is at the forefront of efforts to realize village economic independence by utilizing waste as one of the economic resources. This activity was initiated with the background of problems faced by the community, especially the low awareness of waste management which results in the accumulation of waste in the surrounding environment which has a negative impact on health and environmental aesthetics. Another problem found is the lack of facilities and infrastructure for waste management. To overcome this, the PKM program that is being run carries various solutions designed according to the needs and potential in Banjarwaru Village. The solutions implemented in this program include education and counseling to increase public awareness of the importance of waste management. This educational activity is carried out through counseling and campaigns that directly involve the village community. The PKM team of Cilacap State Polytechnic also provided additional trash bins at strategic points so that people can easily dispose of trash according to its type. With the implementation of these solutions, the main target to be achieved is to increase public awareness of the importance of waste management and the formation of a more structured waste management system. Through education and provision of facilities, it is hoped that the community can consistently separate waste and actively participate in maintaining the cleanliness of the village environment.
