Design and Construction of Mini Single Turbine PLTU Demonstration Equipment: As a Thermodynamics Learning Media

Thermodynamics is often considered difficult for students to grasp because it involves abstract concepts that are challenging to visualize without visual aids or physical demonstrations. This research involves the design of a mini power plant trainer as a teaching tool to visualize basic thermodynamics concepts, such as heat transfer, conversion of heat energy into mechanical energy, phase change from steam to liquid, and thermal efficiency. The trainer is designed according to the requirements of the system provided by the thermodynamics lecturer at the State University of Padang, taking into consideration the teaching material and safety aspects. The power plant trainer consists of four main components, including a boiler with a 15-liter water capacity equipped with an automatic sensor stove that can shut off when it reaches 4 bars of pressure and restarts when it drops below 4 bars, a single propeller turbine, a 12-volt generator, and a vertical condenser with coolant flow in the same direction as the steam flow. The testing results of the trainer yielded a boiler efficiency of 46%, thermal efficiency of 21%, with the steam power generated by the boiler at approximately 1734 Watts, condenser power at 1478 Watts, cooling power to convert wet steam into liquid at 119 Watts, and turbine power at 375 Watts. The maximum electrical power reached 2.94 Watts with a voltage of 12 volts and a current of 0.21 amperes. It took 31 minutes to heat 15 liters of water in the boiler to steam with a temperature of 146°C and a pressure of 58 Psi. The trainer can be operated (can rotate the generator) for 4 minutes until the steam pressure drops to 20 Psi. Based on the testing results, the trainer can be operated smoothly and is capable of illustrating difficult thermodynamics concepts that are hard to visualize. Therefore, in an effort to enhance the quality of learning, this trainer can be used as a simulation tool for thermodynamics education.

Evaluasi Pelaksanaan Pembelajaran Blended learning Pada Mata Pelajaran Alat Ukur dan Pengukuran

— Padang State University in the learning process has used blended learning. Blended learning is a form of learning that combines face-to-face learning with online learning that utilizes the role of technology. Along with the growing role of technology in the world of education, it cannot be abandoned, so that the most effective blended learning method in the world of information technology education is only a means to help smooth the learning process, especially in the form of finding learning resources, but does not completely replace the position and function of a person's role. Educators who provide knowledge and guidance through interaction for students. Through blended learning the learning process is not 100% carried out online, but is used to facilitate the face-to-face learning process in class if the material provided in class has not been delivered and can be accessed online. With blended learning facilities students can learn more freely, because students can interact easily with educators and obtain sources of information or teaching materials both inside and outside the classroom. The platform that can be used for blended learning at Padang State University is E-learning. Therefore, the purpose of this study is to find out how blended learning is applied to measurement subjects and measuring instruments. This research method is quantitative with context and input evaluation methods. The research subjects were students of the Electrical Engineering Education study program class of 2020. Data collection was carried out through a questionnaire or questionnaire with a Likert scale, while the tests carried out included validity tests, reliability tests and data analysis using average values, standard deviation values ​​and determining how much data which will be used score categories 1 to 5. The results showed that of the 9 indicators there is one indicator with an average value of 3.44 which is categorized as good enough, and 8 indicators are in the good category, so it can be concluded that overall it can be categorized as good with an average value of 3.98. From the results of the study it can be concluded that the application of blended learning in the course of measuring instruments and measurements on the context component on campus questions has provided adequate facilities and campus environment for blended learning. However, there is something that needs to be re-evaluated, such as holding socialization about the purpose of implementing blended learning. While the input component has been implemented properly.

How Can Blended Learning and GeoGebra Promote Students’ Achievement in Calculus during the COVID-19 Pandemic?

Calculus is one of the most important courses to take, especially for those studying science and engineering because it can help them understand concepts and formulas in these fields. The COVID-19 pandemic impacts learning in universities globally. Observations from three colleges in West Sumatera (Padang State University, Andalas University, and Padang State Polytechnic) revealed that during the COVID-19 pandemic, students' achievement was unsatisfactory due to entirely online calculus lectures. The study's main goal was to see how blended learning and GeoGebra-based Calculus courses affected student achievement in online learning. The population of this study consisted of 224 undergraduate students from Andalas University who were enrolled in Calculus courses in the 2021 academic year's odd semesters, divided into four classes: A1, A2, A3, and A4, whereas the research sample consisted of two classes (A1 and A4) with 114 students randomly selected. Lectures were held seven times in the experiment and control classes, using blended learning and GeoGebra aid in the experiment class and fully online learning in the control class. A four-question midterm test was employed in this study as an instrument. The test is based on the learning objectives of the calculus course and has been declared valid by experts in mathematics and mathematics education. The findings show that using blended learning and GeoGebra to teach and learn calculus positively impacts achievement. More student collaboration, more student-centered knowledge growth and engagement, more flexibility in learning and teaching, and a well-balanced array of learning resources and methodologies are all benefits of blended learning and GeoGebra. A significant difference was in calculus achievement between male and female students, and there was no interaction between gender and learning factors toward calculus achievement in online learning. Keywords: blended learning, calculus achievement, COVID-19 pandemic, gender, GeoGebra. https://doi.org/10.55463/issn.1674-2974.50.2.6
