Abstract

The implementation of biology learning in the field encounters numerous challenges. Specifically on genetic substance material, students experience learning difficulties due to abstract, interdisciplinary concepts and difficulties in understanding textbooks. This problem can be overcome one way by using learning media. Under current learning demands, technology-based media is appropriate to use. Augmented Reality (AR) based media is one option. The accessibility of augmented reality-based media remains limited, especially for genetic substance material, despite the necessity for media capable of visualizing its complex and abstract characteristics. The results of the needs analysis for teachers and students also show that AR-based media is needed in genetic substance learning. The use of AR media is very possible because of the support of adequate infrastructure. Teachers and students also expressed their willingness to use AR media in learning. Based on the research results, it can be concluded that AR-based biology learning media on Genetic Substance material is urgent to be developed. This media will be able to enrich the variety of biology learning media and become one of the solutions to overcome problems in biology learning, especially genetic substance material.

Abstract

Moringa gum is a product that people can use as an anti-hyperglycemic agent. This study aimed to determine the effectiveness of Moringa gum in reducing blood sugar levels and improving the histology structure of the rat pancreas induced by streptozotocin (STZ). This study used 21 male rats divided into 3 groups including control, diabetes (STZ), and diabetes (STZ + 3% Moringa gum). STZ treatment at a single dose (45 mg/kg BW) was given intraperitoneally, while Moringa gum was given through drinking water for 2 weeks. Blood sugar levels were measured on days 0, 7th, 14th, 21st, and 28th. The results showed that  STZ administration induced diabetes in rats with blood sugar levels of 487 mg/dL on the 14th day.  Moringa gum administration was able to reduce blood sugar levels on days 21st and 28th respectively to 306 and 234 mg/dl. The histology structure of the pancreas of rats treated with gum also showed improvement. This study concludes that Moringa gum is effective in lowering blood sugar levels in rats even though it still does not show normal blood sugar levels, and can repair STZ-induced damage to the histology structure of the rat pancreas.

Abstract

Red algae Eucheuma cottonii is one of the potential marine biodiversity that provides added value in the pharmaceutical and cosmetic fields and is known to have antibacterial compounds. Research focusing on the potential of E. cottonii as an antibacterial is still limited, particularly when it comes to the Aru Islands. This study aimed to measure the antibacterial activity of E. cottonii against pathogenic bacteria including E. coli and S. aereus at several concentrations and to determine the best concentration for inhibiting these two pathogenic bacteria. The study was true experimental laboratory research with a post-test-only controlled group design. Antibacterial tests using the disc diffusion method and phytochemical tests were carried out. This study revealed that E. cottonii could be able to inhibit S. aureus ranging from 0.27±0.03 – 2.1±0.14 at a concentration of 50%-100%, and 0.17±0.05 – 0.45 ± 0.03 against E. coli at a concentration of 80-100%. Meanwhile, saponins and flavonoids were two bioactive compounds found through phytochemical testing. The study concluded that the n-hexane extract of E. cottonii was able to inhibit the growth of E. coli and S. aureus, even with a weak inhibition category. This study recommends that improvements are needed in the E. cottonii extraction process to maximize the antibacterial properties of E. cottonii.
