This study aims to analyze the effect of feedback from local content-based practicum modules on students' science process skills. Research subjects for product trials developed in this study were students of class XI using a purposive sampling technique with a sample size of 60 students. The method used in this research is quasi-experimental (quasi-experimental). The research instrument was a feedback rubric on applying a local content-based practicum module, observation sheets, and tests on the results of Science Process Skills (KPS). Data processing and analysis is carried out by comparing the initial and final science process skills scores by looking at the science process skills N-Gain score. Hypothesis testing uses the T-test to apply a local content-based practicum module on science process skills by analyzing the initial and final science process skills scores. The highest percentage result lies in the indicator of planning an experiment or investigation and using experimental tools and materials, namely 90%. There is a difference between a class that implements a local content-based practicum module and is given feedback with a class that uses a regular module for each class. The experimental class had an N-gain value of 0.75 or in the high category, while the control class had an N-gain value of 0.64 or in the moderate category. There are differences in students' Science Process Skills (KPS) using local content-based practicum modules with conventional practicum modules.

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.

Background: The first labor anxiety is an unpleasant psychological condition due to physiological changes that cause psychological instability. The condition of excessive anxiety, worry, fear without cause, and stress, causes the muscles of the body to tense up, especially the muscles in the birth path to become stiff and hard, making it difficult to expand. This study analyzed the effect of pregnancy exercise on third trimester primigravida anxiety in dealing with childbirth. Methods: Quasi experimental design with nonrandomized pretest-postest control group. The sampling technique used was purposive sampling with 34 research subjects. 17 people for the treatment group were given pregnancy exercise 8 times, and 17 people for the control group were given health education about preparation for childbirth. Results: The results of data analysis using the Wilcoxon signed rank test showed that the average reduction in the treatment group was 8.00 and the control group was 3.00. The effect of pregnancy exercise on third trimester primigravida anxiety in the treatment group with a p-value (0.000) <(0.05), while the control group with a p-value (0.180)> (0.05). Conclusion: There is an effect of pregnancy exercise on third trimester primigravida anxiety in dealing with childbirth in the Wuryantoro Health Center work area.

This study aims to determine the students’ science process skills towards Salt Hydrolysis material in class XI IPA of SMA Katolik Talino Ambawang before and after being given the problem-posing learning model by using Ferris wheel hydrolysis and how much it improves the skills. It is a pre-experimental study with a one-group pretest-posttest design. The sampling technique used is saturated sampling, of which the subjects are 12 students of XI IPA. The normality test used on the pretest and posttest results is the Shapiro-Wilk test, which results in a normal distribution, Asymp.Sig. (2-tailed) greater than 0,05 with a significance pretest of 0,197 and postest of 0,547. The t-test results of the pairing sample indicate that the Asymp. Sig. (2-tailed) value is less than 0.05, which is 0,000 < 0.05. It was concluded that there is a difference between the students’ science process before and after the treatment. The mean scores of the students’ skills before and after the treatment are respectively 45,69% and 82,36%, with a high category. The value of 0,68 from the N-Gain calculation showed that the problem-posing learning model using Ferris wheel hydrolysis on Salt Hydrolysis material improved the students’ skills with the medium category.
