Abstract

Learning cannot be separated from the existence of learning tools. Learning devices are components that are used as a reference for implementing the learning process. The learning process requires appropriate models and strategies to train students' knowledge and attitudes. This study aims to determine the characteristics and feasibility of guided inquiry learning tools using the socio-scientific issue (SSI) to train critical thinking skills and care for the environment of students. The learning tools developed consist of a syllabus, lesson plans, student worksheets, and evaluation tools for question sheets. The characteristics of the learning tools are (1) containing guided inquiry (2) containing socio-scientific issues (SSI), (3) training critical thinking skills, and (4) training environmental care. The research model used is ADDIE (analyze, design, development, implementation, and evaluations) which is modified by using 4 of the 5 stages of ADDIE. The results of the feasibility analysis of the learning device components from the validation results and the teacher/student readability questionnaire obtained very feasible criteria and the evaluation tool of the question sheet was valid. The results obtained indicate that the development of guided inquiry learning tools using the socio-scientific issue (SSI) is feasible to use in the learning process

Abstract

The purpose of this research is to determine the improvement of honest attitude and learning result of human excretion system material using the discovery learning model in class VIII H SMP 5 Semarang semester 2 of 2018/2019. This research is a classroom action research. These research subjects are all students of class VIII H SMP 5 Semarang consisting of 32 people. This research was conducted with pre-cycle, cycle I, and cycle II stages. Data collection techniques are carried out by means of documentation techniques in the initial conditions, observation techniques, and test techniques in the first cycle and second cycle. Data analysis techniques by comparing the variables of honest attitude and learning outcomes in the initial conditions with conditions in the first cycle and second cycle. The results showed that there was an increase in students' honesty in the pre-cycle stage (73.68%), the first cycle (82.81%), and the second cycle (88.28%). There was an increase in learning outcomes before the action (pre-cycle) (59%), cycle I (79.86%), and cycle II (87.06%). Improving students' honesty and learning outcomes becomes a consideration for teachers to use discovery learning models and becomes information material for schools to prepare media or learning materials for discovery learning models.

Abstract

This study aims to develop and analyze the characteristics and validity of the Independent Activity Learning Unit (UKBM) model in learning Macromolecules because of its development to train the cognitive abilities and creativity of vocational high school students. The type of research used is Sugiyono's modified R&D with six steps of development research. The trial step could not be carried out due to Covid-19 constraints. The subjects of this development research were five validators, material experts, and media experts. UKBM validity was obtained from the validator's assessment through a validation sheet using a Likert scale. The results showed that after being validated and revised based on suggestions from the validator, the results of the first study showed that the UKBM developed had the characteristics: according to on basics competence (KD), measure competency achievement, utilizes learning technology, easy to apply, develops HOTS but cannot be separated from LOTS, and 6) attractive appearance. Then, the validity of the UKBM developed by the material validator is 84.66%, which indicates that the UKBM developed is valid, and 88.4% by the media validator, which indicates the UKBM developed is very valid

Abstract

The learning model that can improve students’ critical thinking skills is the Remap Cooperative Script model with the help of Wordwall. This study aims to determine the effect of Remap Cooperative Script assisted by Wordwall on critical thinking skills and to determine student responses from the application of the model. The research method used is a quasi-experimental design. The sample in this study was taken by cluster random sampling technique. The effect of the Wordwall-assisted Remap Cooperative Script model was analyzed using the related t-test. Improvements in critical thinking skills were measured using N-Gain, and measured the results of student response analysis. The influence of Remap Cooperative Script assisted by Wordwall on students’ critical thinking skills as measured by the final related t-test test of 4.12 indicates that there is an influence from the application of the model on students’ critical thinking skills. The increase in students’ critical thinking skills as measured using N-gain in the experimental class was 0.53 while the control class was 0.38. These results indicate that there is a difference in the increase between the experimental class and the control class due to the treatment given. The results of the study were also supported by a very good student response of 82.11%. Based on this, it is concluded that learning using the Remap Cooperative Script model with the help of Wordwall has an effect on increasing students’ critical thinking skills

Abstract

Lake Rawa Pening, in Semarang Regency, is one of the super lakes of revitalization priority. Lake revitalization is an activity to restore the natural function of the lake as a water reservoir through lake dredging, cleaning of invasive alien plants, and land use planning. This makes land use and land cover information in Lake Rawa Pening useful for formulating policy strategies related to revitalization. This study will discuss land cover mapping in Lake Rawa Pening. Mapping using Landsat 9 Imagery and machine learning on Google Earth Engine (GEE). Machine Learning used in this study is CART and RF. The research result shows that the land cover map with the best accuracy is obtained from machine learning RF with an overall accuracy of around 0.78, while CART machine learning is approximately 0.76. The overall accuracy values for CART and RF are not much different because they are both decision tree-based machine learning. This research needs to be developed using cloud masking, comparing image transformations, and comparing its predecessor data, namely Landsat 8. This is useful for providing representative land cover data as the basis for the policy of revitalizing Lake Rawa Pening.
