This research aims to develop teaching practice program model for mechanical engineering education teacher trainees of State University of Surabaya. This research applied research and development (R & D) design by
The development of science and technology provides a significant increase. One of the main examples in the field of heat transfer, In the industrial world, there are several categories of heat exchangers, such as the cooling unit as a supporting medium in industrial areas, there is a double pipe heat exchanger which is an engineering illustration of industrial development. In general, the use of liquid work materials in a job on a heat transfer device still uses liquid work materials with a fairly basic heat conductivity scale. Nano-liquid working materials can be defined as solutions that are useful in improving the thermal properties of molten work materials. In this study, using a working medium in the form of a double pipe heat transfer device accompanied by a liquid working material in the form of Titanium Dioxide (TiO2) nanoparticles with a volume fraction variation of 1%, 3%, and 5%, the temperature constant used is 80˚C as the subject. is being studied. In the use of nanofluids as a mixture in the working fluid, there are stages that need to be considered, such as the SEM (scanning electron microscope) test stage, the Nanoparticle Preparation Stage, the Dispersion/Mixing of Nanoparticles with Base Fluids, the Nanofluid Sonification stage, and the Nanofluid Use Stage in the exchanger. Double pipe heat. In determining the quality and scale of optimization on nanofluids, besides being influenced by the value of the volume fraction of nanofluids and the working temperature used. Thus it can be concluded that the nanofluid mixing process is the main factor in determining the optimization scale and nanofluid quality.
This study aims to: analyze the student learning outcomes using the problem-based learning model, compare to the student learning outcomes using the direct learning model. The type of this study is experimental research that is the factorial design. The study population is all of the students in class X. Therefore, the research sa DLMes are the students of Class X of Culinary Art 1 as the experimental class and the students of Class X of Culinary Art 2 as the control class. The researcher analyzed the data using the analysis of variance (ANOVA) two-way Anova after accoDLMishing the normality and homogeneity test requirement. Based on the result of hypothesis test using ANOVA technique, the researcher found that: (1) the student learning outcomes of cognitive aspects using problem-based learning model was significantly higher than the student learning outcomes using the direct learning model.
The study aims to determine student learning outcomes with direct and problem-based learning models,to determine differences in student outcomes with intelligence levels in direct and problem-based learning models, and analyze the relationship between intelligence levels and direct learning models and problem-based learning models. The method used in this study was experimentation using factorial research design. The design used is 2x2 factorial design, as this design can be used to see students ' learning outcomes before they are given learning and after learning. The results of the study found that: (1) Student learning outcomes using PBL models are significantly higher than those using MPL;(2) student learning outcomes who have higher mathematic logic intelligence using PBL models are significantly higher than students who are taught with MPL models;(3)student learning outcomes who have lower mathematic logic intelligence using MPL models are significantly higher than students who are taught with PBL models;(4) There is a significant interaction between the level of intelligence of mathematical logic, learning models in student learning outcomes. The study concluded that: (1) The PBL learning model can increase the student learning outcomes than MPL models; (2) Students who have a higer mathematic logic intelligence using PBL models, higher learning outcomes than student with MPL models;(3) student who have a lower mathematic logic intelligence using MPL models, higher learning outcomes than student with PBL model, and (4) there is an interaction between the level of intelligence of mathematical logic, learning models in student learning outcomes
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
