This study aims to determine the distribution and trends of student thesis research on science education master study program University of Mataram, in terms of the type of research, the focus of study and research subjects. Data obtained through documentation techniques. Data were analyzed by descriptive qualitative tehniques and continued with FGD. The results showed that 73% of the student's thesis research themes included in the education and 27% belong to the natural science (Biology, Physics, and Chemistry). Education research was dominated by learning methods (50%), media applications and media development (17%), respectively, followed by the development of learning tools (13%) and the competence of teachers (3%). Thesis research subjects was dominated at the level of high school (70%), followed by junior high (25%), S1 (2.5%), and teachers (2.5%). Analysis based on the year thesis from 2009 to 2014 provided information that there were increasing trends on topics related to the development of media and the development of learning tools. Focus Group Discussion recommended that the topics for thesis research in the future which need to be improved are the topic of media development, development of learning tools and topics related aspects of critical thinking.Keywords: thesis research, trends, subjects, education

Abstract

The aims of this study were: 1) to develop a biology practical guidance based on TGT cooperative models equipped with practical performance assessment instrument; 2) to determine the characteristics and suitability of products than have been developed; 3) to know it’s effectiveness in critical  thinking abilities on biology subject of students in class XI. Product development process in this study by following Borg and Gall’s Development. The result of the expert validation by 3 validators showed that each of  the average score in biology practical guidance based on TGT and practical performance assessment instrument were 4,41 and 4,48 and categorized as “very good”. Limited testing conducted on 10 students with high, medium, and low ability. The result of limited testing showed that each of percentage score average in biology practical guidance based on TGT and practical performance assessment instrument were 82,67% and 83,33% and categorized as “very good”. Field trial testing using a pre-test post-test control group design. The data of critical  thinking abilities are tested in this study consist of 5 indicator skills:  (1) formulate the problem; (2) recognize the existence of a logical relationship between issues; (3) collect and collate information; (4) asses and evaluate the statement of facts; (5) Make some conclude were needed. Data analysis were performed  using two independent sample test formula by SPSS 20 for windows. The analysis showed that the critical  thinking abilities for indicator 1, 2, 3, and 5 of experimental group different from the control group, while the fourth indicator not different. Data analysis equipped with calculation of the value of n-gain to determine  the effectiveness of learning by using product that have been developed.

Abstract

Callus induction determines the successfulness of micropropagation through somatic embryogenesis. This research was conducted to determine the effect of 2,4-D and BAP on callus induction of peanut (Kelinci strain). Callus induction was done on MS medium, with the observed variables were of initiation time, diameter, texture and color callus. Statistical analysis showed that 2,4-D and BAP affect the initiation time, diameter, texture and color callus. The earliest initiation of callus formation was obtained from MS medium with the addition of 4 mg/L 2,4-D. The diameter of the largest callus obtained from MS medium with the addition of 3 mg/L 2,4-D + 1 mg/L BAP. Callus color were affected by the treatment of 2,4-D and BAP, while callus texture was not affected by these treatmen, in which compact callus texture was not affected by these treatment, in which compact callus texture was observed in all treatments.Keywords: Induction of callus, 2,4-D, BAP, peanuts

Abstract

This study aims to identify the types of endophytic bacteria on the bark of terap (Artocarpus elasticus) capable of inhibiting the growth of clinical isolate bacteria of Staphylococcus aureus, Escherichia coli, Salmonella typhi, and Pseudomonas aeruginosa. Stages of this study were (1) isolating the endophytic bacteria from the bark of terap plants (2) antibacterial test (inhibition test) against clinical isolate bacteria, (3) biochemical test upon endophytic isolate bacteria showing strong  inhibition effect, (4) moleculer identifcation upon endophytic bacteria isolate showing strong  inhibition effect. From this study, it was obtained 34 barks of terap isolates, and 12 isolates have inhibitory effect on S. aureus. Based on 16S rRNA   molecular identification, the isolate of endophytic bacteria of the barks were identified as Bacillus cereus, Bacillus subtilis and Bacillus amyloliquefaciens. Those  endophytic bacteria of Terap plants  are potentially  to be  developed as a the producer of antibacterial compounds.Keywords: Terap bark, Endophytic bacteria, Identification, Antibacteria
