Abstract

Pektin dikenal sebagai  antikolesterol karena dapat mengikat asam empedu yang merupakan hasil akhir metabolisme kolesterol. Makin banyak asam empedu yang berikatan dengan pektin dan terbuang ke luar tubuh, makin banyak kolesterol yang di metabolisme, sehingga pada akhirnya kolesterol menurun jumlahnya. Pektin banyak ditemukan pada kulit buah-buahan, diantaranya  adalah apel, pisang, dan jeruk. Sejumlah observasi dilaboratorium menunjukan bahwa pemberian pektin dapat menurunkan kadar kolesterol darah. Berdasarkan fenomena tersebut penelitian terhadap perbandingan pengaruh pemberian pektin kulit jeruk bali dan kulit pisang ambon dalam berbagai dosis terhadap penurunan kadar kolesterol darah pada mencit (Mus musculus) menghasilkan: 1) pektin kulit jeruk bali lebih baik di dalam menurunkan kolesterol darah dibandingkan pektin kulit pisang ambon, 2) dosis pektin kulit jeruk bali yang efektif menurunkan kadar kolesterol darah adalah dosis 10%, 3) dosis pektin kulit pisang ambon yang efektif menurunkan kadar kolesterol darah adalah dosis 20%, 4) adanya hubungan yang positif antara kadar kolesterol darah dengan berat hati. Kata Kunci: pektin, kulit jeruk bali, kulit pisang ambon, kolesterol darah, Mus musculus

Abstract

The structure quality of student worksheet will determine the actualization of learning objectives required by curriculum. Besides that, as an effort to support the science development to be more quantitative, biology student worksheets should have the quantitative literacy indicators, such as interpretation, representation, calculation, application/ analysis,  assumption, and communication. This research is aimed to explain the structure quality and the existence of quantitative literacy in biology student worksheets for senior high school. The research method is quantitative descriptive. The subject of this research is 40 student worksheets in biology book for class 11 published by A, B, and C publisher. The result shows that the student worksheets from A has the best structure quality according to Vee Diagram. The percentage of structure quality of student worksheet in A book is  55,5%, followed by B (53,2%) and C (29,9%). The existence of quantitative literacy that can be identified from the books are interpretation, calculation, application/analysis, and communication. All of the interpretation and calculation indicator found in record/transformation component, while all of the application/analysis indicator found in knowledge claim component. Communication indicator found in two components, record/ transformation (50%) and knowledge claim (50%).

Abstract

The problem with this study is that the biological learning outcomes of SMA Lab School UPI students in class XI IPA 1 remain low. The objective of this study is to enhance the biology learning outcomes of students by utilizing image-based worksheets. The researcher conducted classroom action research in two cycles in order to accomplish this goal. This study involves collaborative action research in the classroom that makes use of the Kemmis and Taggart methodology. Students in class XI IPA 1 at SMA Lab School UPI served as the research subjects. Tests, surveys, and observations are the approaches used in this study to collect data. An observation sheet serves as the research tool, and it is assessed qualitatively. Additionally, the concept mastery test results, which are analyzed quantitatively, are supplied. The study's findings indicate that, when image-based student worksheets were used, biology learning outcomes in the nervous system of the classroom were improved, with 19% of students reaching the minimum completeness limit score. Similarly, in cycle I, the average result of the concept mastery test was 77, and 61% of students met the minimum completeness limit score. The average concept mastery score increased to 85 in Cycle II, and a greater proportion of students met the 92% minimum completion criteria.

Abstract

The fast development of internet and mobile technologies prompt this study. Mobile learning technology is accessible and convenient, as students can use advantageous devices to acquire knowledge at any time and location. Mobile learning can effectively meet students' educational requirements in acquiring knowledge. Furthermore, the design of learning materials that are inappropriate for mobile learning might be attributed to one of the reasons of students' cognitive stress. The purpose of this study is to see how mobile learning (Edmodo) on excretory system content affects cognitive load and student concept mastering. This research used a quasi-experimental method consisting of two classes: the experimental class (using mobile learning) and the control class (conventional learning). The instrument used to measure cognitive load consisted of questionnaires of intrinsic cognitive load, extraneous cognitive, and germane cognitive load, while the instrument for mastery of concepts consisted of pre-test and post-test. In addition, there was also a student response questionnaire to review the use of mobile learning in the experimental class. The data that had been collected were analyzed by a descriptive statistic method using SPSS 25.0. The results show that students in both classes have a cognitive load that can be controlled, but the cognitive load in the experimental class was more controllable than in the control class. The result of mastery of concept showed that the experimental class was higher than the control class, with a post-test significance value of 0.001 <0.05. Thus, it can be concluded that mobile learning influence the excretory system material on the cognitive load and mastery of students' concepts.
