Innovation in learning design certainly continues to evolve over time, and so do the needs. Including blended laboratory, which is almost like blended learning, but blended laboratory has characteristics where activities fully use laboratory test results to study theory along with observational. However, blended laboratories must be accompanied by use of the right technology. The presence of the Sophisticated Thinking Laboratory (STB-LAB) in effort to fulfill the implementation of blended laboratory syntactically feels right to be done building collaborative learning and forming collaborative skills of students, and Gather Town as a tool to accommodate blended laboratory is felt very appropriate as a gamification tool. This study aims to find out the implementation of the blended laboratory using STB-LAB assisted by Gather Town as a gamification tool using the Assessment Based on Teaching and Learning Trajectory (AABTLT) with Student Activity Sheet (SAS), and find out the improvement of students' collaborative skills. The results obtained from this study are that all STB-LAB syntax in blended laboratory activities is carried out well, while the increasing collaborative skills results show an increase with very large effect of the Cohen's D Effect Size obtained 2.1 for physics education major and 1.7 for biology education major.

The 21st Century Learning is an increasingly interactive and attractive learning era. The learning process in the 21st century does not only focus on teaching and learning activities in the classroom and explaining theories. There need to be laboratory activities that help provide visuals to students, especially future physics teacher candidates. Various innovations have been made in the development of laboratory activity models. There are still many laboratory activity models that focus on one activity, namely real or virtual. Laboratory activities in the 21st century do not always have to focus on super skills or 4C skills currently in the spotlight and forget about analytical skills and the balance between LOTS and HOTS. This study aims to develop a mixed laboratory activity model that can build 4C skills focused on analytical skills and balance between LOTS-HOTS; in addition, two activities are combined into one, real and virtual. The method used in this research is in the form of Research and Development using the ADDIE model with three meetings in implementation. The results obtained in this study, namely STB-LAB, obtained good model and guide validity results. N-Gain data showed that in the control class, only creative thinking skills were compelling enough, with a value of 59.47. In contrast, in experiment class, only communication skills have an effective enough category with a value of 57.84, but other aspects have an effective category with a value > 76.00. The hypothesis test showed that using STB-LAB could improve students as physics teacher candidate 4C Skills.

Learning media is very important in order to facilitate learning or the income of information. In this 21st century, learning is not only focused on how to get but also how to find. 21st-century learning is also emphasized on digital literacy and also information literacy which is considered a fast door to learning. High digital literacy and information literacy, will facilitate the learning process carried out by students. This study aims to determine whether using LabXChange can improve or facilitate subjects in digital literacy and information literacy. The pre-Experimental design was used as a method in this study with a one-group pretest-posttest design. The research subjects were 15 subjects with a sampling technique purposive sampling. This study obtained the results with H0 = Ha ≠ Hb = Hc, which means, the 15 subjects can increase digital and information literacy with the use of LabXChange as a media for students

Education in the 21st century is an era where learning is unconventional. Interactive learning in the 21st century can be done by conducting virtual or real laboratory activities, even by combining the two in one activity at once. Various innovations in virtual laboratories have spread to optical materials, especially refraction by using a virtual spectrometer. Conceptually, the refractive index is a measure of the bending ray of a light beam as it passes from one medium to another. The refractive index is given by measurement between the refractive index of air, the angle of the prism, and the angle of minimum deviation. The angle of the prism and the angle of minimum deviation can be measured with a spectrometer. The spectrometer is a scientific instrument used to separate and measure the spectral components of physical phenomena and can separate white light and measure individual narrow color bands. Other than an on-hand spectrometer, other tools that we can use to measure the angle of minimum deviation are by using a virtual spectrometer provided by several virtual labs. The study aimed to compare the result of refractive index between on on-hand spectrometer and a virtual lab. Here we report our study on spectrometer whether the virtual lab experiment yields the same results as the real lab. We compare both results of experimental data using data and graph analytics. The results of the study show that the difference in the index of refraction measured between the virtual lab and the real lab is about 0.2%. This shows that there is no significant difference between virtual lab and real lab. [ABSTRACT FROM AUTHOR]

Renewable energy is an energy that can be used to turn on all the energy that is still widely used in the world, including in Indonesia. Solar energy is a renewable energy that uses solar energy as the main ingredient in the formation of electrical energy. Solar energy is one of the most likely energies in a country that is on the equator like Indonesia. One of the interesting problems is how to determine the most effective area for the installation of solar power plants to make the power received by the power plant more effective. This study aims to analyze the effective area for installing solar panels using a Geographic Information System (GIS) as well as mapping of Centralized Solar Power (CSP) and centralized solar photovoltaic (SPV) in the East Priangan area, West Java. The method used in this study is based on the use of remote sensing of the average annual horizontal irradiation (GHI) and Normal Direct Irradiation (DNI). Solar irradiation data (GHI and DNI) were obtained from data from the surface meteorological program and solar energy by NASA, while Land Use/Land Cover, and Digital Elevation Models were used with the use of GIS. The results show that high areas in East Priangan get more effective CSP and SPV results than low areas, but low areas show an average effectiveness value in denuded areas. [ABSTRACT FROM AUTHOR]
