Abstract

The biosorption characteristic of Cd(II) ions from aqueous solution using Lengkuas Merah (Alpinia Gralanga) were investigated as a function of pH. The maximum biosorption capacity of a Lengkuas Merah (Alpinia Gralanga) for Cd(II) was found to be 18,37 mg/L and 91,85% at optimum pH was 10. At pH 2 to 10 the biosorption of Cd ions tends to increase. The result showed that the lengkuas merah  can be evaluated as an alternative biosorbent to treatment waste water containing Cd(II). A Lengkuas Merah is low cost and has considerable high biosorption capacity.

AbstractThis research was instigated by student workbook integrating Chemistry material with STEM that was not yet available.  Since the outbreak of COVID-19, WHO has recommended to temporarily suspend activities that could potentially cause crowds. Therefore, the learning process is carried out online during COVID-19 emergency period.  One alternative supporting the online learning process was by using Moodle learning media in which there was Science, Technology, Engineering, and Mathematics (STEM) based student workbook.  This research aimed at knowing the validity and practicality levels of STEM based student workbook on Acid Base lesson.  It was Research and Development (R&D) with Borg and Gall development model, but it was only until the fifth stagerevising the initial form of the product.  This research was conducted to the twelfth-grade students of MIPA 4 at State Senior High School 2 Tambang.  Interview, questionnaire, and documentation were the techniques of collecting the data.  The research findings showed that STEM based student workbook got the validity percentages from media and material experts continuously 93.75% and 82.2% with very valid criteria, while the validity percentage of Moodle learning media was 78.46%.   The practicality percentage of the workbook was 90% with very practical criterion, and the workbook got positive and good student response with the percentage 90%.Keywords: Student Workbook, STEM, Acid Base, Moodle Learning Media

Abstract

AbstractLearn from covid-19 pandemic, It is necessary to renew, adjust, and improve teaching and learning activities in schools. One of them is by utilizing and developing learning media based on technology that can show various microscopic and abstract concepts that are difficult to display or visualize directly, namely interactive worksheets based on live worksheets. This research was carried out in the 2021/2022 academic year at Senior High School Muhammadiyah Pekanbaru with the main material being is acid-base. The method of this research used was ADDIE (Analysis, Design, Development, Implementation, Evaluation) modeling with limitation up to the implementation stage only. The data taken in this research were in the form of literature studies, interviews, and questionnaires. The data collection instrument of this research was in the form of validity questionnaires and responses questionnaires data. The data obtained were then analyzed using qualitative descriptive analysis and quantitative descriptive analysis techniques. Interactive students worksheets based on the live worksheets on acid-base materials had been tested to be very valid with a percentage of 88.93% from media experts and 82,44% from material experts and got very good response from students with percentage of 92,66%. Based on these results it can be concluded that interactive student worksheets based on live worksheets on acid - base materials are declared to be valid and reliable so that this media is suitable to be applied in the learning process.Keywords : Acid Base, Liveworksheet, E-LKPD

Abstract

The implementation of discussion in learning activities based on problem in schools could improve students' critical thinking skills. However, in its implementation, there were still several problems, one of them was the lack of students' ability in solving the problems. So, there needs to be a learning model that could create the learning based on problem. This research aimed at knowing 1) difference of students' critical thinking abilities, 2) the effectiveness of learning using POGIL model based on SSI students' critical thinking skills. This research was conducted in the even semester of 2021/2022 Academic Year at X MIPA grade of Senior High School Taruna Mandiri Pekanbaru on electrolyte and non-electrolyte solutions materials. It was an experimental research with pretest and posttest nonequivalent control group design. T-test (knowing difference of students' critical thinking abilities) and N-gain test (knowing the level of effectiveness) were used for analyzing the data. The results of this research showed that 1) there was a difference of students' critical thinking skills between the experiment and control groups, the posttest average scores of critical thinking skills in the experiment group was 82.00 and the control group was 75.21, the result of t-test obtained that a significance value was 0.002 < 0.05, so that null hypothesis (Ho) was rejected and alternative hypothesis (Ha) was accepted. 2) Learning using the POGIL (Process Oriented Guided Inquiry Learning) model was effective on students' critical thinking skills. The N-gain value of the experimental group from each student: there were 28 students in the high N-gain category (93.33%) and 2 students in the medium N-gain category (6.67%) who were into the effective category. The conclusion was learning using the POGIL (Process Oriented Guided Inquiry Learning) model was effective on students' critical thinking skills.

Abstract

The low level of students' science process skills is one of the problems faced in the learning process. Aspects of science process skills formulate hypotheses, apply concepts, ask questions, plan experiments, conduct experiments, predict, interpret data, communicate, and conclude. The type of research used is development research. The development model used is the 4 D model (define, design, develop, and dessiminate). This research only tested the validity of the science process skills instrument. The instrument used was a science process skills validity questionnaire. The questionnaire consisted of material, construction, and readability. From the research that has been done, it is obtained that the science process skills instrument on the material of biotechnological innovation phase F 81% with a valid category. The instrument can be used to measure students' science process skills in biology subjects.
