Abstract:Teacher competency is assumed to still be one of the factors that can determine student learning success. This problem needs to be explored further so that the cause can be known with certainty. This research aims to analyse the perception of biological teachers on pedagogic competence of prospective biological teachers in Sikka district. Pedagogic competence is one of the important components that also determine the success of the learning process in school. Prospective teachers need to equip these competencies so that they can apply them in the workforce. The perception of biological teachers on pedagogic competence of prospective biological teachers has a role in determining the progress of the learning process. In conducting this research, the researcher uses descriptive qualitative approach. Data sources come from biology teachers in 6 senior high schools (1 SMA Negeri and 5 SMA Swasta) in district Sikka. In wich the subject of this research is using purposive sampling technique. The data collected through interviews, questionare and document study. The validity of the data is determined using the credibility, transferability, dependability, and confirmability. Data analysis technique used refers to the concept of data reduction, data display, and conclusions or verifications. The results showed that the perception of biological teachers on pedagogic competence of prospective biological teachers in Sikka district belongs to acceptable category, although for the dimension of learning process that can inspire students learning motivation still have problem that need to be improved.

Abstract:Designing experiments is activity-based laboratory learning where laboratory activities lead to scientific ideas which emphasizes qualitative processes that aim to encourage conceptual changing toward the students. Experimental designs made by students are still found many mistakes. These in designing experiments could be minimized by applying vee diagrams. The application of Vee Diagrams helps students in designing experiments, therefor it can minimize the mistakes commonly done in designing experiments especiallyin practical learning. The research method was used is action research consisting of two cycles. The decrease of error in designing experiments is analyzed as a percentage at each research cycle. The data were sourced from third semester biology education students who taking biochemistry courses. Data obtained from the error analysis rubric in designing experiments, questionnaire responses of students in design experiments and vee diagrams rubric. The results showed that the application of vee diagrams can minimize errors in design experiments with the greatest decrease in errors at the stage of making hypotheses while the smallest decrease at the stage of analyzing data.

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.

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
