Abstract

The purpose of the study is to find the best Benzil Amino Purine (BAP) concentrations and proper explants for the growth of the apple cucumber callus (Cucumis sp.) on Murashige and Skoog (MS) media. The research method used was an experimental method with nonparametric statistics with treatments A0B1 (BAP 0 + Leaves), A0B2 (BAP 0 + Stem), A1B1 (BAP 0.5 μM + Leaf), A1B2 (BAP 0.5 μM + Stem), A2B1 (BAP 1.5 μM + Leaf), A2B2 (BAP 1.5 μM + Stem), A3B1 (BAP 3.0 μM+ Leaves) and A3B2 (BAP 3.0 μM+ Stems) and analyzed descriptively using the Kruskal Wallis Test. The parameters observed were callus emergence, callus diameter, growth rate and callus morphology. The results showed accretion of an apple cucumber callus at concentration 0.5 μM BAP + stem which exerted a faster effect on callus formation time (27 hsi), 1.5 μM BAP + stem giving the largest diameter with 1.2 cm. The stem explant gives the best growth rate (0.8 cm/3 day) as well as concentrations of 0.5 μM and 1.5 μM giving the best growth rate (0.462 cm/3 day and 0.887 cm/3 day). This result showed calluses A0B2 and A1B1 (compact + green) as well as A1B2 and A2B2 (crumb + yellowish-green).

Abstract

Termiticide activity of methanol extract of Centella asiatica L. Urban against Coptotermes curvignathus Holmgren was investigated using the no choice test. The chemical components of methanol extract of C. asiatica were identified by GC-MS. The antitermite activity showed that the percentage of termite mortality increased when the concentrations of extract increased. The concentrations of 25% indicated the highest termite mortality which reached 100% on the sixth day. Profiling GC-MS methanol extract of C. asiatica revealed 85 chemical components. Based on MS spectral data, 56 chemical components were identified which were grouped into fatty acids (27.09%), esters (23.73%), hydrocarbons (16.56%), ethers (8.28%), sesquiterpenes (1.61 %), alcohol (1.55 %), aldehydes (3.50%), monoterpenes (1.08%), diterpenes (0.67%), steroids (0.43%), and ketones (0.31 %). Among these, the presence of palmitic acid, patchouli alcohol, and β-caryophyllene may be responsible for its termiticide activity. Other compounds such as triterpenoids, saponins, flavonoids, tannins, steroids, and glycosides that were reported previously not detected by GC-MS in this study, possibly contributing to its activity.

Abstract

The use of electronic teaching materials could increase students’ interest in learning. An electronic module was one of the teaching materials. This study aimed to see the feasibility of the electronic module material for the circulatory system. We used the research and development method. This study’s method had steps that included potential and problems, data collection, product design, design validation, design revision, and product testing. Five validators validated product design. The data analysis used the CVR and CVI values for each criterion in the validation aspect which are course, graphic, contents, and language with a minimum value of 0.99. The study found two important findings. First, from the validator, the CVR values in all elements had a value of 1, and the CVI results each had a value of 1. Hence, the electronic module of the circulatory system material is declared valid and feasible to use. Second, the product trial obtained an overall average score of 88.4% and was very positive. It means that the electronic module could be an alternative teaching material used in the learning process at school or self-study for the student at home.

Abstract

Critical thinking ability refers to an individual's capacity for in-depth thought due to the development of diverse thinking talents, including cognitive capabilities, in response to the acquired information. The purpose of the present study was to investigate the relationship between critical thinking skills, biology learning outcomes, and the visual learning style of students. The study used the correlational research method to ascertain the association between critical thinking abilities and biology learning outcomes among students with a visual learning style in class XI MIPA SMAN 6 Tasikmalaya. To this end, 40 students with predominating visual learning styles were selected from 137 students from class XI MIPA 4-7 at SMAN 6 Tasikmalaya. They were asked to fill in a learning style questionnaire with 23 statements. Moreover, they were asked to answer the nine-question evaluation of students' critical thinking abilities regarding biology topics. Students completed learning outcomes from the Year-End Assessment (PAT) grade XI MIPA in biological issues. Pearson product-moment correlation was employed to answer the research question. The result of the study indicated there is critical thinking ability had a limited association with learning outcomes in students who chose a visual learning approach. The correlation coefficient (R) of 0.365 and coefficient of determination (R2) of 0.133 attested to this. The findings revealed that both critical thinking skills and visual learning styles could predict learning outcomes.
