Physics educational research trends are always changing from time to time. This change follows the phenomenon of educational problems that are developing in the field. The current study is a content analysis of research to analyze the trends of physics educational research that was published between the years of 2018 and 2021, visualize physics educational research trends and how Indonesian researchers contribute to physics educational research. This research was reached through the Journal of Research in Science Education (JPPIPA). Data obtained is 48 data and taken with "physics education" as the keyword. It is aimed to guide the researchers who are planning to conduct studies in this particular field by specifying physics education in terms of their methods, subject areas, research titles, data analysis techniques, and sampling types. Based on the results of the research that has been carried out, it can be concluded that the trend of educational research has increased and is in great demand by researchers in 2021. The physics material that is the research trend is wave material. The subject variable that is often studied is research in the cognitive domain. The trend of physics education research tends to be research that uses quantitative research methods with quasi-experimental design and uses data collection instruments in the form of test instruments. The type of sampling used is school students both junior and senior high school. The trend of physics education research also tends to quantitative descriptive research with data analysis techniques using frequencies, percentages, and charts. Number author or authors are becoming a trend in physics education research as much as three and the number of research references are often used as reference only 1-30. The results of this analytical research can be used to guide and provide references for research that will be carried out by further researchers, especially in the field of physics education research

Arguing ability was a part of critical thinking skills which important to be mastered by the students. In fact, students’ ability to argue was still relatively low. This referred to the TIMSS report (The Trends in International Mathematics and Science Study) in 2011, and showed that Indonesian children’s level in science was positioned in 42 from 45 countries. One kind of efforts to improve the quality of the ability to argue was applying the model of guided inquiry. This study was aimed to develop inquiry-based learning tools (PPBIT) and analyzed its effectiveness in developing the ability to argue of students at SMAN 2 Taliwang-West Sumbawa. PPBIT was carried out by applying 4D procedure. Then, pretest posttest control group design also completely concerned in determining the effectiveness of PPBIT. There were 66 students as the sample which was scattered from two classes and was selected by using purposive sampling technique. The results showed that PPBIT was appropriately to be used for students argumentation skills’ activities by an average of feasibility syllabus 78.71%, RPP 83.5, LKITS 75%, and Instruments KB 80.25%, and effective in improving the ability to argue the class X SMAN 2 Taliwang, particularly on the subject of environmental pollution and recycling of waste by the average score of the students' ability from 48.22 up to 85.08Keyword: PPBIT, Argument

A research on the antioxidant potential of ethanol extract Phaseolus vulgaris L. fractination. The aims study to know fraction had been antioxidant potential and dominant compound at extract fraction. Antioxidant potential fraction is polar fraction and its IC50 is 158 ppm. A dominant compound at nonpolar, semipolar dan polar fraction is phenolic compound. Polar fraction had a greatest percentage phenolic compound (42%).

Survey of questionnaire-based research was conducted to assess the perspective of junior high school (JHS) science teachers on scientific literacy in science learning. Four perspectives for teachers in JHS on scientific literacy were obtained from the research results of the experiments, namely the reading of scientific texts, scientific knowledge, the use of science in everyday life and the use of science-based learning tools. The majority of participants chose the response choice to train all students to apply science learning results in decision-making on daily life challenges. Thus, JHS Science Teachers in Purwakata Regency have a variety of scientific literacy perspectives, but there is no perspective that is considered outside the context of scientific literacy

research on the phytochemical screening of extracts of fruit powder beans (Phaseolus vulgaris L). The aims study was determine the content of chemical compound in extract beans that had undergone a process of heating at high temperature and has been stored in a specified time. Classified of chemical compounds would be included flavonoids, alkaloids, phenols, saponins, tannins, steroids and triterpenoids. Results of phytochemical screening showed bean extract contains the chemical compound class of flavonoids, alkaloids, phenols, saponins, steroids and triterpenoids. Keyword: Phytochemic al screening, bean fruit extracts 

The purpose of this research is to determine the comparison value between e/m of electrons in the use of CRO television tube and use to examine the quality of the experimental method that was is by comparing the experimental method from J. J. Thomson. This research regarded as an experimental method, conducted by measuring the different of light points on the screen television tube to get the radius of electron motion. The data interpreted into a graph to a quaeter radius of current on the coil magnetic field Helmohltz I (amperes). This graph is used to find e/m value of electron and the result is:

Clay mineral is widely used in ceramic materials, building materials, paper coating materials, catalyst support, and an alternative material for zeolite. This paper reports the study on the relationship between the position of soil (low and highland) and its mineral composition in Bukit Tinggi, West Sumatera, Indonesia. It was found that the lowland area indicates the existence of dominant kaolinite and mikasaite. Meanwhile the highland is characterized with dominant illite and kaolinite.Illite is the main component for ceramic. This due to the alkaline condition and high content of Al and K as well as high hydrothermal activity at high land presumably by volcanic activity.Keywords: clay mineral, XRD, XRF, kaolinite, illite-smectite
