Abstract

The existence of Basmati rice among the upper middle class in Indonesia is increasingly popular. Unfortunately, this rice is only grown in northern India and Pakistan. Fulfillment of rice must be imported and the price in Indonesia is relatively expensive. Responding to this phenomenon, the Center for Rice Research (BB Padi), the Agricultural Research and Development Agency succeeded in assembling a special rice variety Basmati. And given the name Baroma, an abbreviation of type Basmati Aromatic rice. And Baroma rice was launched in Subang in 2019 until now it has been recorded that several agricultural lands in Subang have planted this type. The more types of rice varieties, the more types of rice will be found. So that it will make consumers difficult to distinguish between types of rice with one another. Therefore, we need a solution to overcome this problem. And one solution that can be used is to use AI technology, as in the research we did. Using the CNN algorithm produces very good accuracy for detecting types of rice such as the type of data used for training data and test data. From the results of the model training carried out, it produces an accuracy rate of 98,52% while model testing to see how well the model predicts the label correctly is 97,80%.

Abstract

ABSTRACTA study has been carried out on the transmission shaft or main shaft used on the Supra x150 motorcycle vehicle. The material used for the main shaft component is made of SCr420 steel, which is an alloy steel similar to SAE 4118 or JIS SCM 420. The research carried out is the Temper Process with the aim of reducing hardness but increasing other mechanical properties, namely the more ductile nature of the material by how to vary the tempering temperature with the electric current used. This tempering process uses an induction furnace. The electric current used starts from 79 A, ​​80 A and 81 A with a holding time of 15 s, 20 s and 25 s for each Ampere.Tempering process with the required temperature and time is very influential on the hardness of the material. The lower the temperature and the shorter the Tempering process time, the higher the hardness of the material, and vice versa, the higher the temperature and the longer the Tempering process, the lower the hardness of the material.From the results of the tests that have been carried out, it is obtained that some cannot be applied, but if seen from the electric current used, the efficient one is test number 4 because it uses a current of 79 Amperes Keywords: Tempering, Current Strength, Supra X150 Motor, SAE 4118 Steel

Abstract

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.

Abstract

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

Abstract

In an ATV (All Terrain Vehicle) vehicle, the center of gravity is the point at which the vehicle will be in equilibrium. When the vehicle experiences translational and rotational motion at the same time, then at that time The center of gravity will act as the axis of rotation and the trajectory of motion, from the center of gravity This describes the trajectory of the translational motion. The center of gravity is a point of perfect balance or a center distribution of weight. At this point the gravitational force acts, for objects that are have any shape location center of gravity is searched by calculations, calculations are based on the assumption that we can take some points of the object you want to calculate the center of gravity multiplied by the weight at each point then add up and divide by the total weight at each point. It is said that the center of gravity is also the center of mass near the earth's surface, but for a certain height above the earth center of gravity and center of gravity must be distinguished. The distance from the center of mass when viewed from the side view is 0.42 m from the front axle and 0.48 m from the rear axle. The center of mass distance from the rear view is 0.35 m from the right wheel axis and 0.35 m from the left wheel. The height of the center of mass from the axis of the wheel axle is 0,39 m.

Abstract

The working principle of grinding is a grinding stone rotates in contact with the workpiece so that erosion, sharpening, grinding, or cutting. The shape and size of the base material will certainly not correspond to the shape and dimensions of a machine component. On the purchase of a grinding seat, is not included as a complementary tool holder or frame grinding sitting, therefore grinding sitting placed on the floor. It is very uncomfortable in the use of grinding to sit. Therefore, it is necessary to have a tool or a place to put the grinding seated. Tools or place holder for grinding is expected to create more comfortable when sitting grinding process use. Making bench grinder can be done with a series of processes, ie material cutting, making holes, grinding and welding. The strength of the bench grinder that has been made is 29821.26 N so that it can be said that has created a bench grinder is able to sustain grinding.
