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

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

Cardiovascular disease is caused by impaired heart and blood vessel function. Coronary heart disease includes acute coronary syndrome due to narrowing of the coronary arteries. Aspirin is an anti-platelet drug which is commonly used for primary and secondary prevention of coronary heart disease. The effectiveness of aspirin has limitations because 10-20% of patients who use aspirin continue to experience vascular blockage. The haematophagus arthropods salivary glands contain apyrase which can inhibit platelet aggregation and thus a potential candidate for anti-platelet drug discovery. Our studies from salivary gland protein extract of Aedes albopictus found a 67 kDa protein fraction which has a similar molecular weight range from the previously identified apyrase of other mosquitoes vectors. The purpose of this study was to determine the apyrase potential capacity of 67 kDa protein fraction from salivary gland of Ae. albopictus. The present study employed inhibition percentage of platelet aggregation method in determining its apyrase activity. Aspirin was used as a positive control with 2 different concentrations of 0.1 mg/mL and 2 mg/mL. PBS 1mM pH 7.4 was used as a negative control treatment, while negative control without treatment only involved the addition of PRP and ADP. The inhibition percentage activity from the 67 kDa sample ranged from 3-37% whereas the total protein extract comprised of only 1%. The positive control of aspirin was 0.1 mg/mL and 2 mg/mL, resulting in inhibition percentage of 5% and 17%, respectively. The data showed that the inhibition percentage of platelet aggregation from protein 67 kDa is generally higher than those of total salivary gland protein extract as well as positive control. This indicated that the 67 kDa protein has a potential apyrase activity.

Abstract

Malaria and Dengue Haemorrhagic Fever (DHF) are two major tropical diseases in East Java. The pathogens of these diseases are transmitted to human hosts via haematophagy by vector mosquitoes. Anopheles spp. specifically transmits Plasmodium parasites which cause Malaria, while Aedes spp. transmits Dengue viruses that cause DHF. Bangsring, Banyuwangi is one of the endemic areas of Malaria, while Jember is one of endemic areas of DHF. Two species of Malaria vectors i.e Anopheles vagus and Anopheles sundaicus have been found from several samplings which were conducted in Bangsring region. This mosquitoes have been previously identified as a major vector for malaria. Aedes aegypti and Aedes albopictus, which were major vectors for DHF, have been easily found in Jember during our sampling for any season of the year. This research wanted to differentiate the morphological characteristic of those vectors for malaria and Dengue. Adult mosquitoes can be distinguished from one another by characterizing their morphological features. Palpi, wings, and legs characteristics are commonly used as determination keys in Anopheles sp., while thoraxes and legs characteristics are used as identification keys in Aedes sp. Morphological identification is considered as the basic necessity in understanding and determining bionomic of mosquito vector. This is very important in developing effective and efficient mosquito vector control strategies, which is also an important step to prevent the death risks associated with Malaria and DHF cases.
