Abstract

The purpose of this study was to determine student perceptions of vertebrate zoological field study at LIPI Cibinong. The research method used is a descriptive method with survey techniques. The survey was conducted on 52 students of Biology Education department at UIN SGD Bandung. The results showed that 80.2% of students gave positive perceptions of vertebrate zoology field study because according to the students this field study could increase the meaningful learning, expand knowledge about vertebrate zoology, and strengthen the intimacy between students. Also, students believe that the field study is an implementation of Edutainment activities.

Abstract

Chlorella vulgaris is one type of unicellular green microalgae with a cell diameter ranging from 2-8 microns. Pigments in Chlorella vulgaris besides functioning as antioxidant activity but also have a protective effect on retinal degeneration and strengthen the immune system. The purpose of this study was to determine the beta-carotene content of Microalgae Chlorella vulgaris cultured by treatment of light sources and different initial densities of inoculum. The method used was an experimental method, while the design of the study was a complete randomized factorial design consisted of 6 treatments and 3 repetitions. The treatments were light sources neon (32 watt) with an additional red LED, green LED and blue LED each for 16 watt with the Chlorella vulgaris inoculum initial density that was cultivated were 10x104 and 100x104 cells/ml. The result showed that the highest β-carotene content was 721,572 mg/l in the blue LED with inoculum initial density of 100x104 cells/ml.

Abstract

The prupose of this study was to determine the contribution of pedagogic competence and professional competence of biology teachers of the improvement of student achievement in class x high school in the district of Soe City, South Central Timor District, the sample used was 12 teachear with the criteria of being a civil servant, experienced teaching and certified educators from 6 scholls with he number of school students were 60 students from in 2 parallel classes. The method used in this research is quantitative research with multiple linear analysis using the F test, t test and calculating the simultancous determination cocfficicnt R2 wich is processedusing the SPSSfor windos 16.0 applications. Data collection techniques use questionnaires for teachers and tests for studenst to get primary data. The results showed that the contribution of biology teacher’s pedagogic competence of the first partial correlation with t test showed sig. 0,007 < 0, 05, meaning that pedagogic competence (X1) was constant or influential on learning achievement (Y) and professional kompetence of biology teacher’s on the results of partial correlation second with t test show sig value 0,009 < 0,05 means that professional competence (X2) is constant, or influential on learning achievement (Y), so that the influence of pedagogic competence and professional competence of biology teacher’s together is 70% remaining 30% are other factor not examined by researchers.

Abstract

Genus Ficus is important plant for health benefits. Hairy fig (F. hispida) trees grow abundantly in tropical regions and fruiting throughout the year. In West Asian countries, the fruit is commonly used as food and medicinal materials. However, in Indonesia, the fruit has not been utilized. First step in exploring the potential of natural resources for consumption is toxicity test to provide information about safety and adverse effects. This research was aimed to study acute oral toxicity of young and ripe hairy fig fruits using Wistar rats as model. Procedure followed OECD Guideline Test No.420 with modification. Pure filtrate (100 %) of young or ripe fruits were administered orally at volume 1 mL/individual on day-0 in fasting animals. Control received distilled water in the same way. Parameters observed including mortality, sublethal effects, behavior/activities, body weight, complete blood count, as well as evaluation of liver, heart, and renal functions. Results showed that values for all variables fluctuated during the experiment but eventually back into normal range. However, the number of lymphocytes elevated until the end of experiment (day-14) thus increased the total leukocytes count. Accordingly, we are preparing to conduct further toxicity tests to investigate this finding. Key words : acute oral toxicity, Ficus hispida, fruit filtrate, hairy fig, single dose toxicity

Abstract

The paradigm of learning science, including biology continues to show a fundamental shift. Biology is taught not only through conventional inquiry, but also inquiry that envisions the debriefing of student lifelong learning. One strategy that can build this vision is through entrepreneurship oriented inquiry learning programs. In the mechanism, learning is designed into four stages based on conformity with indicators of entrepreneurship, i.e. stage I (basic), stage II (development), stage III (advance), and stage IV (professional). In the learning experience, students are provided with a variety of skills in a comprehensive manner in accordance with the standards of lifelong learning, among which those that will be studied in this paper are Communication and Collaboration Skills. These two standards become important things to study, because learning biology must not only be scientific but also students must be able to communicate their ideas and be able to build teamwork in solving problems. This research was conducted on the V semester students of the Biology Education Department in one teachers college in Central Java who took part in the course on Plant Diversity. The samples involved in the data collection were 31 people. Data was collected using observation sheets and questionnaires in the form of the Communication & Collaboration rubric adapted from Marzano's framework lifelong learning. There are six items in the rubric that represent data, three of which are about Communication Skills and three about Collaboration. The results of the study showed that on average the Communication Skills of students based on the results of observations had developed at each stage, i.e. stage I (2.45), stage II (2.83), stage III (3.17), and stage IV (3.54). In accordance with the Collaboration data students showed significant developments, i.e. stage I (2.47), stage II (2.89), stage III (3.32), and stage IV (3.60). Based on the results of the questionnaire collected before and after learning, the data showed a significant increase in both communication and collaboration skills. Thus it can be concluded that entrepreneurship-oriented inquiry learning programs applied to plant diversity course can improve student Communication and Collaboration Skills well

Abstract

Learning is a process that requires resources as a support in the success of learning. As an educator, teachers must be careful in choosing the learning resources needed by students, so that the learning process can be achieved according to the purpose of learning. But in fact, the learning that teachers do in schools is still not utilizing the media as an appropriate learning resource for students, especially in the understanding of abstract biological concepts that require supporting media for student learning. This study aims to describe differences in student learning outcomes that use interactive multimedia with textbooks in biology learning at senior high school. The method used in this study is quasi-experimental, with Control Group Pretest - Posttest Design. Population in this research is class XI-MIPA I and XI-MIPA II. Class XI-MIPA I as experimental class and class XI-MIPA II as control class. The data were obtained by using a multiple choice test instrument of 30 questions. Based on the results of the pretest and posttest it was found that the average value of the experimental class was greater than the control class. Based on these findings, it can be concluded that there are differences in student learning outcomes that use interactive multimedia with textbooks in biology learning at senior high school.
