<![CDATA[Manufacturing is one of the most valuable industries in the world, it can be automated without limits but still stuck in traditional manual and slow processes. Industry 4.0 is racing to define a new era in digital manufacturing through the implementation of Machine Learning methods. In this era, Machine learning has been widely applied to various fields and will certainly be very good applied in the manufacturing world. One of them is used to predict and prevent defects in metal. The process of predicting and preventing defects in metal is one of the important efforts in improving and maintaining production quality. Accuracy in predicting and preventing defects in metal can be an innovation and competitiveness in technology, both in production methods, and improving product safety and its users. Human operators and inspectors without digital assistance generally can spend a lot of time researching visual data, especially in high-volume production environments. For this reason, there needs to be research in developing Machine Learning technology in an effort to prevent the occurrence of defects in metal. And one of the development of this technology by using Convolutional Neural Network (CNN) architecture Visual Geometry Group 16 layer (VGG16). As for the metal defect dataset with 10 classes with details for training data as many as 17221, and test dataset as many as 4311, From the use of methods and datasets available, has been done training model used and produce very good accuracy, that is equal to 89% and testing with accuracy equal to 76%. And also done Interpreter process against new input data, to know metal defect type, prediction accuracy and appropriate action to prevent and overcome metal defect type result of Interpreter process application.]]>

<![CDATA[AbstractCurrently, metal joining techniques in the field of welding have developed rapidly. In constructions that use metal raw materials, most of the joints are made by welding. Apart from joining, the welding process can also be used for repairs, for example to fill holes in castings, make coatings on tools, thicken worn parts and other repairs. Welding is also widely used for building construction, bridges, piping and automotive. As we know, there are many types of welding used today. One of them is Gas Tungsten Arc Welding (GTAW) or commonly called Tungsten Inert Gas (TIG).AISI 1045 steel is referred to as carbon steel because it complies with international coding, namely the 10xx series based on the nomenclature issued by AISI and SAE (Society of Automotive Engineers). The first number 10 is the code that indicates plain carbon, then the code xxx after the number 10 indicates the carbon composition. So AISI 1045 steel means carbon steel or plain carbon steel which has a carbon composition of 0.45%. Steel of this specification is widely used as a component of gears, shafts and bearings. According to its function, it must be able to withstand wear and tear due to friction with the chain. Wear resistance is defined as resistance to abrasion or resistance to dimension reduction due to friction]]>

<![CDATA[In its development, every manufacturing industry increasingly makes people think more creatively and are faced with new problems, especially in making new innovations. The aim of these production problems is to achieve production targets more quickly and efficiently. The metal machining process is an important factor to support the final quality of the product, but there is one obstacle that must be faced, how to determine the appropriate manufacturing process to make a product with better accuracy. The increasing development of technology in the casting manufacturing sector due to consumer demands for better quality encourages the industry to innovate, the process of making automotive components, especially connecting rods, currently uses metal molds with the aim of improving the quality of these components. The connecting rod functions to connect the piston to the shaft. This component can be a bridge for combustion power and can be channeled directly to the crankshaft. Please note that a car engine can go fast because the piston hits the crankshaft and the connecting rod which is the connecting rod. Without a connecting rod, the car will not be able to accelerate optimally A design process has been carried out to make a connecting rod mold using Master Cam X5, to produce Code G which will be used to make a mold on a CNC machine. The material used is Alamunium 2024.]]>

<![CDATA[The use of a belt conveyor is one of the choices of facilities or tools used to transport or move materials or as a means of transporting materials, both bulk materials and individual materials. One of the machines that requires a conveyor is a corn cob sheller and chopper machine which was created in 2022. by Majalengka University students. This tool has a problem, namely, the corn that has been shelled cannot automatically go straight into the chopping machine, so a design is needed that takes into account the safety factor and the correct conveyor speed. This is of course for safety and ensures that the conveyor can transport corn which has a density of 760 kg/m 3 at a slope of 300 ‰. For this reason, the conveyor that best suits these needs must have specifications with a total belt length of 0.295 m, drum pulley diameter of 3 in or 0.0762 m, shaft diameter of 20 mm with a length of 500 mm, 150 watt electric motor drive, 16T small sprocket gear and 24T large sprocket with chain number 35. Safety Factor (SF) on the Belt Conveyor frame has a minimum SF value of 6.3, with a maximum tension of 32.5 N/mm2 and yield strength of 204 N/mm2 and a belt speed of 0.5 m/s.]]>
