Abstract

This research is an experimental study that aims to determine the differences in the learning outcomes of class XI students of SMA Negeri 12 Maros who are taught using the Mind Mapping learning model and the conventional model on the Excretion System Principal Material. The sample in this study were students of class XI MIA 1 and class XI MIA 2 SMA Negeri 12 Maros. The experimental class was taught using a mind mapping model, while the control class was taught using a conventional model. Based on the results of data analysis obtained a sig value of 0.001 0.05, it can be concluded that there is an influence on student learning outcomes using the mind mapping learning model in class XI SMA Negeri 12 Maros.

Abstract

Lung cancer is a disease that is in the top 10 causes of death globally. It is caused by CYP1A1 and YWHAZ genes expressed in the lungs. One of the solutions offered for lung cancer sufferers is gene therapy. Gene therapy for lung cancer is focused on the knock-down of expressed CYP1A1 and YWHAZ genes. It can be using shRNA transfected into lung cells by lentivirus. The lentivirus envelope is modified using glycoprotein filovirus, one of which is ebolavirus. Lentivirus pseudotyping can recognize certain cells. Especially, Ebolavirus can recognize lung cells. The lentiviral gene is designed to carry the gene of interest (shRNA) but no the infectious gene. The shRNA gene transfused into lung cancer cells will recognize and complement the specific target mRNA sites of the CYP1A1 and YWHAZ genes. After that, shRNA will cut the mRNA which should be expressed into a cancer protein. Unexpressed mRNA into protein causes cancer cell growth inhibited. Thus, this gene therapy solution is expected to be able to reduce the rate of death caused by lung cancer. Keywords: Lung cancer, CYP1A1 and YWHAZ genes, gene therapy, lentiviral, shRNA

Abstract

This study investigated into effects of science learning materials on performance and retention of biology concepts among senior secondary school two students in Afijio local government area of Oyo State. The study was Quasi-experimental involving pretest, posttest equivalent group design. In this design, 40 students were randomly selected from SS2, pretested to ascertain their group equivalence, and then divided into two groups (experimental and control) using the lottery method of sampling techniques. The experimental group was taught biology concepts with science learning materials,while the control group was taught the same concepts without science learning materialsfor three weeks. The two groups were pretested and post-tested for performance and retention, respectively. The data collected were analyzed using a simple percentage method, mean, and standard deviation. Based on the data generated and results obtained from the experiment, the findings revealed that the use of science learning materialsin the leaching of Biology concepts significantly improves the academic performances, enhances the retention ability of students involved in the study. The study also revealed that students exposed to the use of science learning materialsin the teaching of biology concepts generally had better academic performances and retention ability than students who were not exposed to the use of science learning materialsin the experiment. The study recommended, among others, that the Ministry of Education should provide science learning materials for effective teaching and learning of Biology concepts in Oyo State Senior Secondary Schools. Keywoard: Science Learning Performance, Retention, Biology Concepts

Abstract

Most antimicrobial agents, antifungus or antibacterial have been isolated from plants. Purwoceng (Pimpinella pruatjan Molk.) is one of the potential plants that produced an antibacterial agent. But, the status of purwoceng as an endemic plaint in Central Java is "endangered". The endophytic bacteria of the roots can produce an antibacterial agent. The research was performed by purified the endophytic bacteria isolate, the antagonism test as an antibacterial against Staphylococcus aureus also performed, and the data obtained were analyzed descriptively Keywords:  Endophytic Bacteria,  Pimpinella pruatjan Molk., Staphylococcus aureus

Abstract

Test the Effectiveness of Basil Leaf Extract (Ocimum basilicum L). Against Bacteria Escherichia coli aims to know the ability of basil leaf extract (Ocimum basilicum L).deadly or inhibit escherichia coli bacteria. This research is qualitative experimental research.Basil leaves are extracted using maceration method using entanol solvent 96%. Antibacterial tests are conducted by administering treatment to bacteria with three types of concentrations, namely concentrations of 40%, 60%, 80%, positive control, and negative control.Antibacterial test results of coarse extract of basil leaves (Ocimum basilicum L) have the ability to inhibit escherichia coli bacteria at concentrations of 40%, 60%, and 80% with each halo zone diameter of 1.96 cm, 1.11 cm, 0.89 cm, 1.50 cm, 0.00 cm.Coarse extract of basil leaves (Ocimum basilicum L) has the ability to inhibit bacteria (bacteriostatic) with the most strong halo zone diameter at a concentration of 40 % with a halo zone diameter of 1.96 cm. Key word: Effectiveness Test, Ocimum basilicum L., Escherichia coli

Abstract

The seventh grade science teacher at MTsN 3 Kota Pariaman has problems in developing an instrument for assessing higher order thinking skills. In the 2013 curriculum, teachers are required to be able to provide questions in the C4-C6 domain, namely High Order Thinking Skills (HOTS). This study aim to produce a valid and practical assessment instrument for higher order thinking skills on environmental pollution material at the C4-C6 cognitive level. The background of this research is that the questions made by the teacher are still at the C1-C3 level and there are still obstacles for teachers in developing higher order thinking skills assessment instruments, while inthe 2013 curriculum teachers are required to be able to provide questions in the C4-C6 domain. This type of research is research development (Research and Development) which is a research method used to produce certain products. This type of research uses 3 stages of the 4-D model, namely the define, design and develop stages.Based on the research conducted, a very valid assessment instrument of 3,32 was produced by thevalidator, the empirical validity there were 30 valid questions and 10 invalid questions, the reliability in this study was 0,77 with the category of reliability, 94,79% teacher practicality and practicality. students amounted to 80,80%, the difficulty level of the questions was between 0,31 to 0,70 with moderate criteria and the question difference had sufficient criteria. This research can be used as a reference for other researchers related to the development of higher order thinking skills assessment instruments.Keywords : High Order Thinking Skills, Validity
