Abstract

The purpose of the study was to improve the biology learning outcomes of students in class XI IPA 3 at SMA Negeri 5 Kendari. This study was conducted in the second semester of the academic year 2013/2014. The research design of this study was a Classroom Action Research (CAR) with three learning cycles. Each cycle goes through four stages: (1) planning; (2) implementing actions; (3) observation and evaluation; and (4) reflection. The data source of this study were students who were measured by using the learning outcomes test of the cycle I, cycle II, and cycle III. The data obtained were analyzed using descriptive analysis. Biology learning outcomes of Class XI IPA3 students at SMA Negeri 5 Kendari taught using the Probing-Prompting learning strategy showed an increase in each cycle namely cycle I by 71.78%, cycle II by 86.35%, and in cycle III it reached an average of 87 47%. Based on the results of the study concluded that the Probing-Prompting learning strategy could improve the learning outcomes of biology students of class XI IPA3 SMA Negeri 5 Kendari.  Keywords: Probing-Prompting Strategies, Learning Outcomes

Abstract

Bad quality of the questions is one of the factors that can lead to errors in the grading of student learning outcomes. It gives a lower students’ score than the appropriate score and will give an impact on school grades (NS). In this case, school grades (NS) have an effect of 40% in determining the passing of national exams (UN). Therefore, this study was conducted to assess the quality of first semester final exam items made by biology class XII teacher based on some aspects; they are the material, construction, and language. In this study, the researcher used purposive sampling technique in order to collect the data. Items were assessed using a multiple-choice item evaluation sheet which has been declared valid by an expert validator. By combining the material aspects of the assessment data, construction, and language, research results obtained in general show that of the 120 items assessed, there are 104 ( 86,7 %) items with excellent criteria and 16 ( 13,3% ) items with right criteria. Thus, the items made by biology class XII teachers are still suitable for final semester exam of the 2013/2014 academic year Sidrap Regency.

Abstract

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 in the 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 the validator, 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.

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.

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:  Staphylococcus aureus, antibacterial, incubation, Purwoceng, secondary metabolite

Abstract

Chili is one of the plants that are needed by the community so that proper cultivation techniques are needed, in this case related to fertilization by utilizing organic animal waste.This study aims to determine the response of the growth and production of red chili (Capsicum annum L.) to chicken and cow manure dose combination. The method used is an experimental method with a factorial completely randomized design which consists of two factors, namely the first factor is the type of animal manure which consists of two levels, namely cow dung and chicken manure, the second factor is the dose of fertilizer there are three levels, namely 200 grams, 300 grams and 400 grams. The total combination of treatments was 9 treatments and 3 replications so that in total there were 27 units. The parameters observed were chili growth (height and number of branches) and chili production (number of fruits and fruit weight). The data were analyzed of variance with 5% and 1% levels, followed by Duncan's 5% further test. The results of the analysis showed that the combination of treatments had a very significant effect on plant height and fruit number (12.77 and 5.00), significantly affected the number of fruits (3.55), but did not affect the wet weight of fruit (2.46).Further test results showed that the best treatment for the parameters of plant height, number of branches, and number of fruit was a combination of 300 grams of chicken manure and 200 grams of cow manure. Keywords: dose, chicken manure, cow manure, growth, production
