Learning media is one of the most important component in a learning process, both inside or outside a classroom. In order to provide proper learning for students based on the researcher’s prior research, at least, three different field tests are needed. This research is a quasi-experiment, which is provide result of the second field test of cellulose degrading bacteria from mangrove soil microbiology handout both in cognitive and psychomotor ability. The research aims are to describe effect of this microbiology handout on student’s cognitive achievement and gain data about inappropriate laboratory written instruction in this handout. Data gained by conducting learning activities using developed handout which were 2 times in class theory and three times of practical activity using instuctions written in the handout. In the end of class theory activity, students did a posttest to confirm their improvement of cognitive ability while their practical ability was observed using observation sheet along with their activities. Results showed that handout which being tested could improve student cognitive at average level (n gain 0,419). In contrast, several parts of laboratory written instruction need to be fixed to make better microbiology handout.

Publisher : Journal of Biological Science and Education

Diseases caused by parasitic groups received less serious attention from the farmers because the disease is chronic morbidity and mortality rates and small. However, if observed further, parasitic diseases can lead to secondary infection by bacteria, viruses, and fungi that can cause death and high losses. This study aims to identify the types of ectoparasites red tilapia (Oreochromis nilotica) at Fish Seed Center (BBI) Ranomeeto, South Konawe. This type of method used was observational and sampling was done by using purposive sampling, ie taking into account the characteristics / criteria sample has been determined. These samples included 30 individuals of red tilapia fish taken from BBI Ranomeeto South Konawe. Observations ectoparasites done in Laboratory of Department of Biology at Halu Oleo University . From some of the samples examined Trichodina sp. found to infect the gills, skin and fins. Ichthyophthyrius sp. found on the skin. The dominant type of ectoparasites found is kind Trichodina sp. with a prevalence of 60% and Ichthyophthyrius sp. with a prevalence of 46.67%.

Learning in schools before the pandemic was carried out directly in schools, but because of the pandemic, it required teachers and students to carry out the online learning process. Teachers and students experience many obstacles in the online learning process, especially for students new to online learning. This study aims to describe students' difficulties in online learning during the Coronavirus disease (COVID-19) pandemic and to find out the causes of students' problems in online learning during the Coronavirus disease (COVID-19) pandemic class VIII Madrasah Tsanawiyah Khudrinnur. This research is a qualitative descriptive study. The samples in this study were students and teachers of class VIII MTsS Khudrinnur. The research instrument is a questionnaire or questionnaire, interviews, and documentation. From the results of the study, it is known that the factors that affect the difficulties in online learning of students are network difficulties of 69.09% of the total number of students. So it can be concluded that the factors that influence students' difficulties in online learning are network difficulties, about 69.09% of the total number of students. Factors do not have a quota of about 68.75 % of the total number of students. The factor of not having a cellphone (HP) is about 66.40% of the total number of students. The aspect of not understanding the material is about 58.85% of the students who do not understand the learning material will ask the teacher when they do not understand. The cool factor for playing games is around 71.35% of students prefer to play games compared to participating in online learning. Keywords: Difficulty, Online (Online), MTSS Khudrinnur

Publisher : Journal of Biological Science and Education

Growth is the process of increasing the number of cell protoplasm in an organism accompanied by an increase in size, weight and number of cells that cannot return to their previous state. One of the factors that influence the growth of koi carp is feed. Good feed is feed that can meet the nutritional needs of the koi carp. The addition of tapioca flour in the feed formula, which contains artificial feed, tapioca flour, and water in the koi carp feed, is one of the proper steps because of the increase in carbohydrate doses that can support the growth of the koi carp. This study aims to determine the benefits of adding tapioca flour to the artificial feed of the koi carp (Cyprinus rubrofuscus) and to determine the effect and the most appropriate dose of adding tapioca flour to the artificial diet of the koi carp (Cyprinus rubrofuscus). The research method used is a quantitative research method accompanied by direct observation and analysis of research data, which is also accompanied by a literature study method from previous studies to support the findings in the research results. The results showed that the more feed formula was given, the faster the growth of the koi carp produced. But must be accompanied by the right dose, which is 8 grams of feed formula once a day. While the benefits of adding tapioca flour in carp feed are increasing carp production, prolonging goldfish life expectancy, increasing efficiency and nutritional content in carp feed, increasing carp appetite accompanied by increased growth.

Lentiviral shRNA Construction in Gene Therapy for Knock Down CYPIA1, and YWHAZ gene in Lung Cancer Henik Anjayati
Journal of Biological Science and Education Vol 3, No 1 (2021): June
Publisher : Journal of Biological Science and Education

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

Publisher : Journal of Biological Science and Education

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.
