Abstract

Abstraction is the primary key in computational thinking. This study aims to analyze students’ computational thinking skills of abstraction on the concept of kinematics. The data were collected through students’ project documents and interviews. The data is examined using a content analysis approach that emphasizes writing, verbal, or visual communication. The results revealed that students’ abstraction skills were evident in collecting data and analyzing, and recognizing patterns but were less visible in building models or simulations. Abstraction skills can be used as a foundation and framework for viewing a concept in physics not only in mathematics or formulas views but as a data iterative relationship. This research is expected to provide an overview for physics instructors to integrate computational thinking in their learning classroom

Abstract

The aim of this study is to analyze the need for teaching materials in the Biology Learning Strategy course that are in accordance with the needs of lecturers and students to support learning in the modern era. The design of this research is exploratory research. The research subjects were ten lecturers in Biology Learning Strategy courses or similar courses from seven universities and 102 biology education students who had gone through Biology Learning Strategies courses from Universities in Surakarta and DIY. Data collection techniques are observation and questionnaires. Analysis of questionnaire data using Rasch modeling. The results of the study indicate that the obstacles faced in learning the Biology Learning Strategy course are the absence of teaching materials that can be used as a guide in the learning process. The results of the questionnaire analysis of lecturers and students are above the logit item value of 0.00 which shows the respondents agree on the importance of the Biology Learning Strategy course and that teaching materials are needed in the form of textbooks. The conclusion of this research is that it is necessary to develop a textbook with the characteristics of Blended Collaboration Problem-Based Learning to support the Biology Learning Strategy course.

Abstract

To compete in the 21st century, educators need to equip students with various skills called 21st-century skills. The purpose of this research is to identify and describe the perceptions of biology education lecturers and students regarding the authentic assessment of 21st-century skills. The method used in this research is an internet-based survey method. The research participants consisted of 7 lecturers and 80 students majoring in biology education. The instrument used is a result questionnaire consisting of 11 questions for lecturers and ten questions for students. The survey results show that lecturers and students know about the components and urgency of 21st-century skills. In addition, the assessment of these skills is also quite often done. However, there are still some obstacles in authentically assessing 21st-century skills.

Abstract

Tea tree is an essential oil-producing plant from Australia which is also found growing in several parts of Indonesia, including the island of Lombok. So far, tea tree essential oil producers on the island of Lombok do not utilize by-products in the form of hydrosol (distilled water) produced in the process of making essential oils. In this study, the characterization and analysis of the chemical composition of the hydrosol of tea tree leaves growing on the island of Lombok was carried out. The characteristic aroma of hydrosol is similar to that of tea tree essential oil. The results of the GC-MS analysis also showed that the hydrosol of tea tree leaves also had similarities with the essential oil, composed of major compounds in the form of trans-caryophyllene (28.58%), limonene (13.98%) and terpinen-4-ol (16.27%). Other compounds detected were -pinene (4.14%), -pinene (6.50%), -myrcene (8.09%), -terpineol (10.10%) and -terpinene (5.77%).
