Abstract

The rapid development of artificial intelligence has now been widely used in various industrial fields, with various benefits that make it easier, speed up work processes, automate and be efficient in resources to improve cyber security and can be implemented easily and of course will continue to be developed further, such as In the agricultural industry, artificial intelligence can be used to identify certain types of fruit or plant leaves and their level of maturity. This research will create a machine learning application to identify the level of ripeness of tomatoes with 3 types of tomatoes, old tomatoes, young tomatoes and rotten tomatoes. From each type of tomato there are 50 object images in the form of images in .jpg format, of which 15 object images are used as training data and 35 images as test data to detect tomato images using the Backpropagation method which will utilize image feature extraction in the form of RGB colors. The results obtained from testing images of young, old and rotten tomatoes obtained an accuracy rate of 83%.

Abstract

Round bar material with a diameter of 25,4mm is a type of material commonly used in the field of building construction and machinery spare parts. At PT. Vale Indonesia Tbk., this material is fabricated according to its design, which is called a puncher bar. A puncher bar is a tool used to clean the tuyere hole from nickel matte blockages in the PT converter section. Vale Indonesia. A series of cleaning processes can cause the puncher bar to bend at the ends or in the middle. The bent puncher bar was straightened manually in the production workshop of the Soroako Technical Academy. The process of straightening the puncher bar manually is considered less effective in terms of safety, time efficiency and worker productivity. The design of this machine consists of several components, namely the machine frame, electric motor, speed reducer, gears, towing roller, and towing roller. The stages of making a machine start from design, manufacturing, assembly, and testing. The puncher bar straightening machine has dimensions of 930 mm x 702 mm x 1129 mm with a main drive of a 5.5 HP electric motor with 1440 rpm. Vee belts and gears as rotation transmitters. The towing roller uses AISI 4140 alloy steel with a diameter of 5 inches and the guide roller uses mild steel with a diameter of 4 inches. This machine can straighten puncher bars with a maximum bend of 6 cm with a final bend of 1.5 cm with a processing time of 1 minute
