Abstract

Centrifugal casting has advantages including more dense castings, low porosity, and high productivity. Factors that influence the results of centrifugal casting such as mold temperature, rotational speed of the mold and the centrifugal force that occurs. The purpose of this study was to determine the effect of the variation of aluminum alloy upright centrifugal casting molds on impact toughness and microstructure in the manufacture of karts wheels. This research is using experimental method. The independent variables in this study were 700 rpm, 800 rpm and 900 rpm mold rotations. The dependent variable is toughness and microstructure. The control variables are mold temperature 250 ° C and pour temperature 750 ° C. Data analysis using descriptive analysis methods and one way ANOVA that is equipped with further tests. Data obtained from the test results in the form of numbers are then presented in tables, graphs and described based on the results of the analysis conducted. The impact toughness test results are that the higher the mold rotation, the greater the toughness value. The highest impact toughness is in the 900 rpm mold rotation specimen of 0.013036 J / mm2. Anova test results obtained the influence of rotational mold variations on impact toughness. Further test results found a significant influence of 700 rpm and 900 rpm mold rotations. The results of microstructure testing are that the higher the round of the mold, the smaller the area of Si grain formed.Keywords: vertical centrifugal casting, variation of mold rotation, impact toughness, micro structures

Abstract

The preparation of adaptive learning models for children with special needs is important because nowadays there is no policy set out in providing appropriate education services based on their specific needs. The slow learner inclusivity type is currently could be accommodated in regular schools. Therefore, this study aims to develop a model of learning services for slow learners. Using research and development methods, we conducted qualitative analysis for model preparation and quantitative analysis to analyze its effectiveness. The curriculum adaptation service model used is substitution. The results of the trials showed that there was a significant average difference before and after the implementation. Providing learning services with this model can make children better at responding to conversations and working with others, able to do independent activities, and able to control concentration in learning. These results require more operational policy support so that they can be implemented more easily.

Abstract

Project-based learning is used as a reference for developing the ability to create and update because it is seen as having characteristics that effectively direct students to investigate essential ideas and questions, framed through the discovery process, able to accommodate the different needs and interests of students, directing freedom in making products or services and presentations that exceed what the teacher hopes, requires the ability to think creatively, critical thinking, the ability of information to find and write conclusions and present material, and relate to real and authentic problems and the latest issues. Multimedia is a medium for delivering information that contains complete material because it presents the material in writing and is equipped with videos and evaluation tools. The next difference is self-regulation as the variable studied in addition to learning outcomes. The results showed that project-based learning improved student learning outcomes, as evidenced by the Wilcoxon test results with a significance value = < 0.05. Learning outcomes shown from knowledge tests and performance tests are influenced not only by the students' ability to practice based on the theory being learned but also by their ability to self-regulate (self-regulation). The correlation between self-regulation and knowledge learning outcomes is 0.465, and the correlation between self-regulation and practical learning outcomes is 0.890, with the significance of each test of 0.000 < 0.05. It shows that the learning outcomes of cooling system knowledge and practices are influenced by self-regulation. Project-based learning tools assisted with multimedia are effective as a learning model for class XI students of light vehicle engineering at Public Vocational High Schools in Semarang City are classified as valid. Multimedia-assisted project-based learning is effective as a learning model for class XI students of light vehicle engineering at Public Vocational High Schools in Semarang City. This multimedia-assisted project-based learning can improve learning outcomes, achieve completeness and be better than project-based learning. Self-regulation affects class XI students' learning outcomes of light vehicle engineering at Public Vocational High Schools in Semarang City.
