Abstract

Crabs are macrobenthos with characters that are attached to or resting on a base or live on basic sediments. The role of crabs in the ecosystem includes converting nutrients and enhancing mineralization, increasing the distribution of oxygen in the soil, helping carbon life cycles, and providing natural food for various types of aquatic biota. This research was conducted in the estuary area of ​​the Meru Betiri National Park (TNMB) Resort Bandealit. Identification results from 37 individual crabs at the Estuary Resort Bandealit Meru Betiri National Park (TNMB) obtained 5 species from 2 families (Portunidae and Sesarmidae). In the family Portunidae, there are 3 types, namely Scylla tranquebarica, Scylla paramamosain, and Scylla olivacea. Whereas in the family Sesarmidae found 2 types, namely Parasesarma pictum and Parasesarma cognatum. Keywords: Crab, Bandealit Resort, Identification

Abstract

Abstract Bacillus thuringiensis is one type of bacteria that has been used as a microbiological control agent for pests and a vector of plant disease. The presence of Cry proteins inside the B. thuringiensis can be acted as a specific insect repellent that only toxic to certain insects. The CryI protein is toxic to Lepidoptera insects which can attack various types of plants. Polymerase Chain Reaction (PCR) is a common method that can be used to amplify the gene encoding CryI proteins from B. thuringiensis. This research aimed to design a good primer candidate for cryI gene amplification from B. thuringiensis. In silico analysis for designing cryI primer was carried out using some software, such as BLAST for searching cryI gene sequence, Bioedit for sequences alignment, and DINAmelt for analyzing dimer structure of primers. Ten primer candidates were successfully obtained based on the result of the primer3 software. A pair of primer was selected to amplify the cryI gene, with forward primer 5’- CGGTGAATGCCCTGTTTACT -3’ and reverse primer 5’-CGGTCTGGTTGCCTATTGAT -3’. Amplification of the cryI gene by PCR method using selected primer resulting in a PCR product with a length of approximately 200 bp.

Abstract

Staphylococcus aureus is an opportunistic pathogen and cause of nosocomial infection, which has leukocidin and can reduce immunity. Because of antibiotic resistance, immunomodulator is an alternative treatment for S. aureus infection. Polysaccharide krestin (PSK) from Coriolus versicolor extract contains active β-glucan that triggers immune responses' effectiveness including phagocytosis. This research aimed to know the activity of PSK against phagocytosis ability on mice infected by S. aureus. There were six treatment groups. 100 mg/kg BW PSK was given to the mice strain Balb/C by gavage. S. aureus was infected once every two weeks. Phagocytosis ability consisted of phagocytic activity and capacity, counted on slide smears of mice intraperitoneal fluid. The results showed that PSK increased phagocytic activity in the group giving PSK after infection. Furthermore, the most effective giving PSK on phagocytic capacity was before and after infection. Based on this research, PSK increased immunity by phagocytosis ability and can be useful as an immunomodulator.

Abstract

Apart from the importance of scientific literacy for the pre-service teachers as the key to success in becoming a teacher who can teach and make literate students, not many studies have revealed the contributing factors, especially the learning experience students. This study aims to measure the level of scientific literacy skills of pre-service students and contributed factors. One hundred and five students at state Islamic universities in Indonesia participated in this study. The data were collected in three stages. First, the level of scientific literacy skills using the Test of Scientific Literacy (TOSLS). Two students with the highest and lowest abilities in each batch were interviewed. Finally, the semester learning plan (RPS) and practicum instructions are reviewed. The mean was used to describe the level of scientific literacy skills, and one-way ANOVA to test differences in skill between the four groups based on the spent year in university. Data obtained from interviews and analysis were analyzed using content analysis techniques. As a result, pre-service biology teachers have a "medium" level of scientific literacy skills. There was a difference between the four groups with the highest and most significantly different fourth-year students. The primary cause of scientific literacy skills is the student learning experience in terms of learning strategies, assignments, evaluations, and practicums activities that are obtained by pre-service biology teachers. The results suggest the following implications for teaching: faculties must identify scientific literacy skills and carry out learning with learning strategies, assignments, evaluations, and practicum activities that support the growth of scientific literacy abilities of a pre-service biology teacher.

Abstract

Leaves are an important organ for plants. One part of leaf is stomata which function as a place for gas exchange. The method used in this research is the observation of the morphology and anatomy of frangipani leaves (Plumeria acuminata) which are exposed to pollution and not exposed to pollution. The purpose of this study was to determine environmental conditions or as a bioindicator by observing damage to plants. Macroscopic damage to plants in leaf morphology and microscopic damage to changes in leaf stomata conditions. Observations show that the morphology of frangipani leaves (Plumeria acuminata) which are not exposed to pollution is larger than frangipani leaves (Plumeria acuminata) which are exposed to pollution. The number of stomata in the abaxial part is more than the adaxial part. Meanwhile, the number of stomata on frangipani leaves (Plumeria acuminata) that were not exposed to pollution was more than those exposed to pollution. The stomata type on frangipani leaves (Plumeria acuminata) is anomocytic type with kidney-shaped covering cells.

Abstract

This current research aimed at investigating the structure and average size of New zealand rabbit’s spermatozoa. This research employed experimental design and was conducted in Chemical Engineering Laboratory of State Polytechnic of Malang and Biology Laboratory of University of Muhammadiyah Malang. This research was initiated from August to September 2019. The design of this research was specifically Completely Randomized Design, with four treatments of tannin extraction of Pluchea indica, and control with oral nasogastric with the dose of 3 ml/kgbb in four-time repetitions. A light microscope and Scanning Electron Microscope (SEM) were used for observation. One-way ANOVA was used for data analysis. As for the control group, the spermatozoa were found normal. Whilst, with reference to the three other treatments, the spermatozoa were seen to be abnormal, with apparent dilation in the neck, pseudo-droplet (bumpy neck), and dag defect (twisted tail). Based on the results, there was an influence of tannin extraction of Pluchea indica on the abnormality of New zealand rabbit’s spermatozoa (with p<0.05). Regarding the size of the spermatozoa, the average length of spermatozoa was 8.74 µm for the head, 1.86 µm for the upper neck, and 56.48 µm for the tail. With reference to HOS (Hypo-Osmotic Swelling) test, it showed that abnormal spermatozoa was in the form of severance of the head and the tail, as well as dag defect. To sum up, this research has indicated that the condensed tannin extraction contributes a similar effect to that of the pure one on the structure of spermatozoa.

Abstract

The 21st -century learning demands students’ that have critical thinking skills. The learning model of Brain-Based Learning (BBL), combined with the approach of Problem-Based Learning (PBL), is an alternative model that adjusts the critical thinking skils. The objective of this research was to generate a valid, practical, and effective BBL-PBL learning model. This research was research and development using the ADDIE model, consisting of analysis, design, develop, implement, and evaluate. The study was implemented on the tenth-grade students of Rambipuji Senior High School, Jember, Indonesia, in the academic year of 2019/2020. The data collection techniques used were validation of products and test methods, interviews with the teachers, the questionnaire responses of teachers and students, and class observations. The results of the validity of the product were 91.4% as very valid category. The results of the cognitive model’s effectivenest were of 0.81 as high category, the psychomotor aspects were 82 as fair category, and the critical thinking skills were of 85 as excellent category. The practicality results were obtained from the questionnaire responses of the teachers and the students, respectively by 91.2% and 86% which are both excellent categories.
