Abstract

ABSTRACT – The process of edge detection on aluminum 1100 material as a result of welding tungstent inert gas (TIG) has been successfully developed, difficulties in the edge detection process due to the large number of impurities in the form of vertical streaks on the weld metal can be overcome using several methods. Of the many methods used, double thresholding and hysterisis have the most important role and contribution in the process of cleaning impurities. The hough transform process requires setting the number of meeting lines to get two lines with rho = (229, 146) and theta = (1.582496, 1.553343). Method 4 is the shortest method of pre-processing until line detection, namely GS > Gauss > Sobel > DT > Hys > HT. In further development, the development of an interface that makes it easy to vary the threshold value and the number of meeting lines, then the pixel/mm or pixel/cm scale calibration process needs to be carried out.

Abstract

ABSTRACT – Manual tofu cutting is often time-consuming and less efficient, necessitating innovation to enhance productivity. This study aims to design an automatic tofu cutting machine as a replacement for the manual cutting process. The method used is Participatory Rural Appraisal (PRA) with an experimental approach. The design process involves simulations to determine the machine's technical specifications, resulting in a minimum pneumatic piston diameter of 24 mm, an inertia of 88,281.25, and a maximum stress of 0.24 N/mm². Testing shows that the machine can cut 112 pieces of tofu in 3.8 seconds. These results indicate that the automatic tofu cutting machine significantly improves the efficiency and speed of the cutting process compared to manual methods. This research contributes to the development of more efficient food processing technology applicable to small-scale industries.
