The Effectiveness of Flipbook and Video to Improve Students' Critical Thinking Skills in Science Learning during the COVID-19 Pandemic

Critical thinking is one of the skills that must be possessed in studying science. During the Covid-19 pandemic, flipbooks and videos can be used as alternative media to improve students' critical thinking skills. This study aims to determine the effectiveness of using flipbooks and videos in improving the critical thinking skills of junior high school students during the pandemic. The method used in this research is descriptive quantitative. The data collected were in the form of students' pretest and posttest scores. The data were analyzed using the N-gain test and Independent Sample T-Test. The results showed: (1) learning videos were effective for improving students' critical thinking skills with an average score of 0.44 (medium) and (2) flipbooks were effective for improving students' critical thinking skills with an average score of 0.42 (medium). There is no significant difference between students' critical thinking skills, both after using flipbooks and videos.

Analysis Of The Results Of Studying Physics From Student Learning Habits

The Effect of the Type and Composition of the Adhesive on the Physical Properties and the Rate of Combustion Hyacinth Biobriquettes

This study aimed to identify the effects of variety and composition of the adhesive used to the physical properties and the rate of combustion hyacinth biobriquettes. The physical properties referred to are water content, density and heating value. This research is an experimental study with a literacy study conducted in 3 stages, preparing tools and materials, making biobriquettes, and testing biobriquettes. The main ingredients used in the manufacture of biobriquettes are water hyacinth which is obtained at the Batujai Dam, Central Lombok Regency and the adhesive materials used are wheat flour, tapioca flour and cement. The method used to test the water content and density of the biobriquette was oven, while the calorific value and the rate of combustion were by heating water from the biobriquette combustion. The results showed that the biobriquette water content ranged from 5.138% - 13.953%, density 0.412 g/cm3 - 0.513 g/cm3, calorific value 2984.520 cal - 4476.780 cal, and combustion rate 0.029543 g/s - 0.042431 g/s. Based on the test results, it is known that the addition of adhesive material causes the water content, density, and combustion rate of the biobriquette to increase but the calorific value tends to decrease.

Description of students' Integrated Science Process Skills on Friction Material on a Flat Field

Science Process Skills have an important function in the process of student curiosity and scholarship, so it is necessary to do a description of students' science process skills. This study aims to describe students' integrated science process skills on friction material on a flat plane at SMPN 9 Muaro Jambi. The observed science process skills consist of ten observation indicators, namely experimental analysis, planning experiments, conducting experiments, describing the relationship between variables, defining variables operationally, making data tables, obtaining and processing data, making hypotheses, identifying variables and making graphs. This type of research is qualitative research with descriptive type. The research subjects were students of class VIII at SMP Negeri 9 Muaro Jambi which consisted of class VIII D and VIII E. The sampling technique was total sampling where the total sample was 40 students. While the data collection technique uses observation sheets that have been validated by a team of experts. The data that has been obtained were analyzed using descriptive statistical techniques with the help of IBM SPSS statistics software. The results of the research on students' mastery of integrated science process skills in the friction practicum on the flat plane were classified into the good category with a percentage of 57.5%. This means that students have good science process skills, because most students are skilled at doing practicum based on experimental indicators. The conclusion of this study shows that the integrated science process skills possessed by students are categorized as good.

Quality Analysis of Briquettes based on Waterding with Variation of Pressure and Pellet Geometry to Water Content and Value of Calories

This study is a research on water hyacinth-based briquettes which shows the calorific value of each form of briquettes. The purpose of this study was to analyze the quality of water hyacinth briquettes with variations in pressure and pellet geometry. The quality analyzed includes moisture content and calorific value. The method of making briquettes starts from charcoal, pounding, then mixing with tapioca starch adhesive. The composition of the mixture used is 90% water hyacinth charcoal with 10% tapioca starch adhesive. 4 geometric variations are used, namely, solid box, hollow box, solid tube and hollow tube with 3 pressure variations, namely, 10 PSI, 20 PSI and 30 PSI. Test results and analysis,briquettes at a pressure of 20 PSI produces a calorific value range of 91.15 - 150.14 cal / gram. The resulting calorific value is higher than the briquettes at a pressure of 10 PSI and 30 PSI with a heating value range of 93.84 - 148.79 cal / gram and 89.81 - 135.39 cal / gram. Hollow briquettes produce a calorific value range of 107.24 - 150.14 cal / gram higher than solid geometric briquettes which produce a heating value range of 89.81 - 148.79 cal / gram. So that the contribution of the results of this research is that the community makes briquettes with shape and pressure with good results shown in this study.

Description of Student Discipline Attitudes at SMP Negeri 16 Jambi City

Attitude is a form of one's perception of an object which is depicted through the expression of accepting, rejecting, or ignoring. Discipline attitude is the accuracy in following the rules of the game that has been agreed upon. The purpose of this study was to describe the disciplinary attitudes of student learning towards four indicators in SMP Negeri 16 Jambi City. The research method uses descriptive research. The instrument used was a learning discipline attitude questionnaire. The sample in the study amounted to 69 students. The sampling technique in this study was total sampling. The research instrument used was a learning discipline attitude questionnaire. The questionnaire data were analyzed using descriptive statistics with the help of SPSS 21. The results showed that the learning discipline attitude of dominant students in the category always consisted of 2 indicators, namely obeying and obeying school rules and good attention when learning in class, and also The attitude of student learning discipline is dominant in the frequent category which consists of 2 indicators, namely managing study time at home diligently and regularly studying and doing assignments. Based on the results of the study, it was found that students' learning discipline attitude at SMP Negeri 16 Jambi City in 4 indicators had a positive attitude in the always and often category.

Students’ Attitudes based on Adoption of Scientific Attitudes and Interested Expanding Time Learning Science
