Abstract

Rejuvenation and conservation of mangrove ecosystems, especially the Teluk Awur mangrove ecosystem, Jepara Regency, can be done by using bacteria that are capable of supporting plant growth or called Plant Growth Promoting Rhizobacteria (PGPR). One of the mechanisms that support plant growth by the PGPR group is phosphate dissolving activity, because the phosphate in the soil is in the form of a compound that is difficult for plants to absorb. This study aims to determine the character of Rhizobacter isolates as a superior phosphate solvent in dissolving phosphates in-vitro from the Teluk Awur mangrove ecosystem, namely isolates coded EO-4. These isolates have similar microbiological and biochemical characters to the genus Enterobacter. Molecular characterization of isolates was carried out using the Polymerase Chain Reaction (PCR) method - 16S rRNA sequence analysis (comparing with 16S rRNA sequences in gene banks). The results showed that the phosphate-solubilizing rhizobacteria that were isolated had the same base pair percentage of 48% with Enterobacter pyrinus (access number NR_028875).

Abstract

Diabetes mellitus (DM) is characterized by an increase in glucose levels in the blood due to disorders of glucose metabolism in the body. The pancreas organ of people with DM has a weakness in producing the hormone insulin. As a result, the distribution of blood glucose to other organs of the body is inhibited so that glucose levels in the blood increase which causes DM sufferers to experience longer wound healing than normal humans. Binahong leaves contain alkaloids, saponins and flavonoids which have antibacterial activity which can accelerate the wound healing process. The purpose of this study was to determine the antibacterial effect of binahong leaf extract ointment (Anredera cordifolia) against Staphylococcus aureus bacteria from diabetic wounds. This research includes antibacterial test for binahong leaf extract ointment (Anredera cordifolia) with variations in the concentration of 10%, 20%, and 30% of the concentration of binahong leaf extract of 25% which resulted in a wound coverage percentage of up to 100%, namely at 30% ointment concentration. The conclusion of this study is that there was no wound closure for negative control and positive control in the form of oxytetracycline, the percentage of wound closure was 85%.

Abstract

Misconception is a concept that is different from the concept that has been agreed upon by experts. Misconceptions can cause students to understand concepts incorrectly. This study aims to identify misconceptions in high school biology textbooks and their relationship to misconceptions in students. This research is a meta-analysis with a literature review method on data sources in the form of articles in electronic journals. This study examines the results of the analysis of high school biology textbook misconceptions and student misconceptions from 15 relevant articles. Based on the results of this study, it is known that 12 high school biology textbooks have misconceptions with low, medium, and high misconception categories. The misconceptions contained in the textbooks are on average classified in the low to medium category, but there are also textbook misconceptions that are included in the high category. The results of the analysis of students' misconceptions revealed that students experienced misconceptions in the medium to high category of the 14 high school biology materials tested. Three common causes of misconceptions in students are misconceptions in textbooks, misconceptions in teachers, and misconceptions in students' initial concepts. Thus, it can be concluded that misconceptions in textbooks are one of the main causes of students' misconceptions, which results in students understanding the material incorrectly. This is evidenced by the fact that students experience misconceptions, especially on material that has misconceptions in textbooks.

Abstract

Misconceptions understand concepts that are different from scientific concepts that have been approved by experts in their fields and can cause difficulties for students in understanding material. On average, there are still many students who still experience misconceptions in Biology material with different percentages for each material. The purpose of this study was to examine the results of the analysis of students' misconceptions on Biology material from 7 articles selected from 32 relevant sources. The type of research used is a meta-analysis with literature review research methods through literature studies using several data sources such as articles in electronic journals and books. The results showed that students experienced misconceptions in high school biology material studied by researchers in source articles with different percentages. Continuous misconceptions can harm students and prevent students from understanding the material well, which will result in students failing to understand new concepts, and it will continue with other related material.
