Abstract:
The potential for solar energy in Indonesia is abundant and attractive to be developed into one of the leading renewable energy sources. Photovoltaic or solar cells are devices that can be used to convert solar energy directly into electrical energy. A dye-sensitized solar cell (DSSC) is an exciting type of solar cell to be developed because it is cheap, easy, and can use natural dyes based on plant extracts. However, the performance of DSSC degrades when it is at high operating temperatures. In this article, a narrative review is presented to improve the efficiency of DSSC by integrating with a solar collector in the form of a photovoltaic/thermal (PV/T) system. The solar collector will act as a heat absorbent from the DSSC, and the heat energy obtained will be used to distill ethanol. Optimization in the ethanol distillation system can take advantage of CuO as a nanoparticle in the working fluid or better know as nanofluid.

Abstract:
Understanding the concept is an important aspect of solving various physics problems. Understanding the concept will help in understanding the problems, determining problem-solving strategies, and using mathematics appropriately as a problem-solving tool. Lack of conceptual understanding results in the tendency to solve problems by relying solely on formulas without knowing the proper use of formulas according to the underlying concepts of the problem. Various problems related to rotational motion can be explained through the concept of torque. To solve the problem of torque, understanding the concept of torque and mastering the concept of vectors are needed to find solutions to the problems Many of the science teachers have a background in physics education. Science teachers who are a bachelor of physics education should master various physics concepts even though the material is not taught at the junior high school level. Therefore, the authors conducted research to determine the ability of science teachers with an education background in physics education in solving the problems of torque. The study involved 10 science teachers who teach in 10 different schools. This research was a descriptive study with data collection techniques in the form of a questionnaire using an essay question to test the science teacher's ability in solving the problems of torque. The results showed that most of the participants could not solve the problem of torque due to a lack of understanding of the concept in determining the torque generated by forces with various positions.

Abstract:
Prospective teacher education is faced with the issue of integrating technological pedagogical and content knowledge (TPACK). Prospective teachers are expected to become teachers who are skilled at teaching effectively, mastering content, and are able to utilize technology in the learning process. The ability of TPACK for prospective science teacher can be seen from the preparation of a lesson plan, because there are elements of pedagogy, content, and technology in it, and it is seen from the suitability of the lesson plans with the implementation of learning by teachers in the classroom. Moreover, in implementing science learning, students must apply a scientific attitude to support learning so that students not only understand the theory but also master real concepts. The purpose of this study was to analyze the skills of prospective science teachers to apply TPACK in preparing lesson plans so that the weaknesses and strengths could be identified. The research method used is library research, by examining several sources related to the skills of prospective science teachers in implementing TPACK through the preparation of the lesson plan. The results of the research showed that some prospective science teachers still lacked skills in using integrated technology in the preparation of lesson plans, and the implementation of learning was not optimal so that it became a big challenge that science teachers had to face in the industrial revolution 4.0. Implementing TPACK in the preparation of the lesson plan can improve the quality of learning. The advantages produced can be seen from the effectiveness of the learning process provided through the use of technology in learning.
