Abstract

The floor scrapping method for cowshed cleaning systems has been widely applied on several modern farms today with the aim of making it easier for farmers to clean the cowshed. The mechanical design of the motor-driven scraper aims to facilitate the cowshed and save human energy. The design method uses James H. Earle method and is continued by carrying out the production process for the cowshed cleaning systems. This system works using a chain to pull the scraper so that it moves to scrape dirt on the floor by pushing it, so that work that was previously done manually can be done more easily with the help of this tool. The designed tool has dimensions of 1000 mm x 500 mm x 300 mm, while the mechanical beam design has dimensions of 700 mm x 200 mm x 3 mm. Based on the calculation results, bending stress data was obtained of 20.534 N/mm2 for the frame and 41.476 N/mm2 for the scraper. Calculation of the transmission system for the cowshed cleaning tool obtained specifications for an electric motor with a power of 0.02 HP, a pulley measuring 72.6 mm, a belt measuring 26 inches, a shaft measuring 12 mm and rolling bearings with a life of 24 years. Then, from the result of testing the frame and scraper using Solidwork software, it was found that the stress was 29.95 MPa for the frame and 67.49 MPa for the scraper. This stress value is declared safe because it is still below the permitted stress. Meanwhile, based on function testing, the most effective nozzle to use is a nozzle with an angle of 15o because it has a higher spray intensity than the others and thus has the highest cleanliness value. Based on test results, the cowshed cleaning tool obtained an average cleanliness score of 75.6 with a time of 60 seconds.

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.
