Using a single machining strategy on the entire model can lead to long machining times and poor surface finish quality. The steep and shallow strategy can efficiently detect parts of the model that have steep contours and those that have shallow contours. In other words, this strategy can analyze the model surface angle at runtime to identify and divide the machining zone based on the slope angle or commonly called the threshold angle. In this context, the selection of the threshold angle is very important when carrying out the finishing process on free-form surfaces to produce a good surface quality. This study was conducted to determine the optimum threshold angle that can produce the minimum surface roughness between steep areas and shallow areas. Threshold angles that were varied were 20°, 30° and 40°. Machining was carried out using Ballnose type cutting tools with a diameter of 6 mm. Then the stepover and stepdown is 0.1 mm for the finishing process on the surface of the propeller product made of Aluminum by using a CNC Milling machine. From the experimental results, the most optimum threshold angle is at an angle of 40° with an average roughness value in the steep area of 1.9 mm and in the shallow area of 1.3mm and a total average roughness of 1.6mm.","PeriodicalId":14149,"journal":{"name":"International Journal of Engineering, Science and Information Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88011009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An electrocardiograph method is required to diagnose arrhythmia. Electrocardiogram, ECG, is the result of this Electrocardiograph process. The ECG is then utilized as a diagnostic tool for arrhythmia. Because the ECG data is so extensive, an adequate processing procedure is required. Understanding the ECG data can be done in various ways, one of which is classification. Naïve Bayes is a classification technique that can handle enormous amounts of data. ECG data has a lot of characteristics, which makes classification more difficult. Feature selection can be used to eliminate non-essential features from a dataset. This research aimed to determine the feature selection’s impact on the Naïve Bayes classification. It was proven by increased accuracy by 4%, precision by 0.13, recall by 0.13, and f-measure by 0.14. The computation time was 0.03 seconds faster. The highest performance was obtained by classification with 80 features. The accuracy was 93%, precision and recall were 0.45, f-measure was 0.42, and computation time was 0.10 seconds.","PeriodicalId":14149,"journal":{"name":"International Journal of Engineering, Science and Information Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74439351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Product design is important to carry out the production process. Product design helps estimate and analyze requirements with more accurate results than without doing this process. The design in this study was carried out using the Solidworks 2020 software. The dimensions of the machine obtained from the design results were 330 mm long, 330 mm wide, and 285 mm high with a mass of 1.59 kg. The novelty of the design that has been made is the addition of a feeding spring, so that the material input process is more stable and safer. Feeding springs can also improve the quality of the cut. In addition to making the design, a simulation of the calculation of the maximum von Mises value is also carried out with the aim of knowing the safety factor of the design that has been made. From the simulation results, the maximum von Mises Stress value of Force 1 is 1,470 MPa, and Force 2 is 9,846 MPa. This value is obtained from the provision of Force 1 32.49758 and Force 2 18.718. This value is far below the yield strength of the material (250 MPa) so it can be concluded that the design is safe to proceed to the production process.","PeriodicalId":14149,"journal":{"name":"International Journal of Engineering, Science and Information Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78252897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This material was chosen because it has many advantages compared to other materials, namely it has better resistance, relatively affordable production costs and is easy to shape. PT.X is one of the manufacturing companies engaged in fiberglass, namely the manufacture of pipes and body from vehicles. In this case study the company still uses hand milling and manual processing. Fiberglass pipe in this company is molded indirectly to the size requested by the customer, therefore a cutting process is needed to get the required pipe length. The blade used specifically is a diamond-coated cutting blade because the fiber material is not heat-resistant. In this research, the researcher wants to design a fiberglass pipe cutting machine with an adjustable holder that can be adjusted so that it can cut various pipe sizes. Making the design of this machine is done using Fusion 360 software. The making of the machine includes the cutting process, grinding process, and welding process.

The many disadvantages of metal materials due to their large mass, difficult manufacturing processes, corrosive properties, and high production costs have resulted in reduced use of metal materials in various products. Nowadays, there are many replacement materials with mechanical properties that can resemble metal materials such as composites. The role of composites is very important in the development of today's industrial world. This study wanted to determine the effect of the composite composition of rias banana fiber and teak sawdust with epoxy resin on the mechanical properties of the composite. The results showed that the comparison of the composition of the composite using rias banana fiber and teak sawdust with an epoxy matrix had an effect on the mechanical properties. Increasing the percentage of resin composition increases the value of the surface hardness of the composite. The highest level of Rockwell hardness with a value of 117 HRB in sample D and the lowest 109 HRB in sample A. While the highest max strength value was produced by sample C with a composition of teak sawdust: rias banana fiber: epoxy is 20% : 40% : 40 %.

To be able to make food, of course, the cook must prepare the ingredients in advance to be processed into ready-to-eat dishes. Often people have a lot of food ingredients but don't know how to process them. Cooking without seriousness, of course, some people fail when making a dish. Back then, people depends on recipe that was passed down from generation to generation. Now, the digital world is growing rapidly. Anything can be done with increasingly modern technology. Everything needed is accessible with today's technology. Everything is so easy, including the matter of food. Even so, in this digital era, people use smartphones but still cannot use them properly. Many of them use search engines so they need to sort out which are real recipes and which are just random recipes. The purpose of this study is to help people find recipes by taking photos of food ingredients and then finding out what can be made from these ingredients. This technique uses Artificial Intelligence (AI) with MobileNet and Tiny YOLOv2 SSD modules. The design uses the Unified Modeling Language (UML). The study used experimental methods to test the accuracy of the AI used. Data collection will be utilizing a literature study. This research uses agile for system development.
