Abstract

Haemodialysis is a treatment effort that aims to support the life of patients with end-stage renal failure which can lead to psychological experiences that can affect the well-being of life such as depression, anxiety, and stress increase the risk of losing the meaning of life. The design in this study was cross-sectional and involved 46 haemodialysis patients and the sample was selected using a purposive sampling technique. The data were tested using a non-parametric spearman rank analysis to find the correlation between self-esteem and levels of depression, anxiety, and stress. The results of the analysis show that there was a significant correlation between self-esteem and levels of depression, anxiety, and stress, which were marked with a significance value of 0.001 each. The resulting coefficient values ​​were negative respectively -0.726, -0.016, and -0.674. Based on this value, it can be concluded that if self-esteem is low, the level of depression, anxiety, and stress will increase in haemodialysis patients.

Abstract

This study aims to determine the feasibility of psychomotor assessment instruments in chemical separation practicum. This research is research and development. This development uses the ADDIE model which is adapted into 3 stages, namely analysis, design, and development. The subject of this research trial involved 8 chemical separation practicum assistants. The data collection instrument used was a feasibility validation sheet and a practicum assistant response questionnaire. The feasibility of the psychomotor assessment instrument in the chemical separation practicum was validated by 3 experts covering the feasibility of content, presentation, and language. Content feasibility obtained an average of 91.67%, presentation feasibility obtained an average of 94.44%, and language feasibility obtained an average of 83.33% with all aspects showing the criteria "Very Eligible". Then the response results of the chemical separation practicum assistant obtained an average of 80.68% with the "Good" criteria. Psychomotor assessment instruments are very suitable for use in the learning process to support the assessment of the results of chemical separation practicum.

Abstract

Intermolecular forces are one of the topics in basic chemistry. Intermolecular forces consist of abstract concepts that require multiple representations (macroscopic, submicroscopic, and symbolic) to visualize those concepts. Moreover, the multiple representations are needed to help students understand the abstract concepts of intermolecular forces. Multiple representations were presented as pictures, diagrams, and animation in the videos. The aims of this research are to develop a video of intermolecular forces based on multiple representations and to determine the level of validity and student’s responses to the video. This study employs the 4D method formulated by Thiagarajan which consist of 4 stages. However, this study only adopted 3 stages; define (to know the problem), design (manufacture of product to solve the problem), and development (to determine the level of validity and student responses). The instruments used in this study were the validity and the response questionnaires. Data collected were then analyzed using the percentage criteria proposed by Riduwan. The video provides the conceps and real-life example of the London forces and hydrogen bonding. Video validation shows the level of subject matter validity is 95,38%, media validity is 98,89%, and language validity is 91,11%, where all the aspects were very valid criteria. Every aspect is validated by 3 experts. Student responses on a limited scale by 7 students show a percentage of 87,8% and a large scale by 20 students of 88,9% with very good criteria. Based on the result, the video can be used in the study of intermolecular forces

Abstract

This study aims to determine whether there is any difference in the communication skills of students who use the cooperative model of type Two Stay Two Stray (TSTS) with students who use the conventional model and how much influence the communication skills of students using cooperative model type Two Stay Two Stray (TSTS) with students which uses the conventional model. The method used is pre-experimental design with Intact draft-Group Comparison. Samples were students of class XI SMA Muhammadiyah 2 Pontianak MIA. The results of the data analysis assessment of communication skills of students in the experimental class and control class using testIndependent Samples T-test, shows the differences in communication skills between classes that use the cooperative model of type Two Stay Two Stray (TSTS) and class that uses the conventional model. The results were obtained, there is a difference in communication skills of students who use the cooperative model of type Two Stay Two Stray (TSTS) with students using conventional models. Based on the calculation, the results indicate that the influence of cooperative learning type Two Stay Two Stray against the communication skills of students at 51.6%.
