Abstract

Each student has various characteristics in carrying out the learning process. But so far, learning is often done without regard to this diversity. The research method in this research is the descriptive research method. The instruments used were initial assessment instruments to identify learning styles, low vision PDBK special needs assessments, and daily assessment instruments for Virus learning concepts. Identifying students' learning styles determines the type of learning media given to students. Students with audio learning and visual learning styles are given learning media in audio-visual videos, while students with kinesthetic learning styles are given learning media in the form of puzzles. From the results of observations, it was found that one student with special needs (PDBK) had low vision and was then given learning media in the form of a text/PowerPoint file with a larger and thicker image size. Differentiated learning based on learning styles and the needs of students can improve student learning outcomes, including low vision PDBK. This can be seen from the results of the daily assessment of viral concept, which has increased. The research results show that differentiated learning by providing different learning media according to the learning styles and special needs of students can improve student learning outcomes on Virus concepts.

Abstract

Indonesia has a geographically rich region with medicinal plants, including Cassia alata. The utilization of this medicinal plant still needs to be improved, including documentation of its use as medicine. Information about the extract of Cassia alata leaves as an anti-diabetes therapy can be conveyed to future generations. This research aims to prove the potential of Cassia alata leaf extract as a hyperglycemia therapy material through a mouse model. The research design uses a pretest-posttest group design. The antidiabetic activity of Cassia alata leaf extract in vivo is determined by the indicator of reducing blood sugar levels in mice with hyperglycemia, supported by quantitative testing of secondary metabolite compounds. The experimental animals used 24 male Balb/c mice induced with 0.75 mg/kgBb alloxan. Measure blood sugar levels in mice with hyperglycemia after treatment with Cassia alata leaf extract at concentrations of 25%, 50%, 75%, and 100%, and a positive control using metformin—data analysis using one-way ANOVA correlation analysis. Cassia alata leaf extract is proven to contain alkaloids, flavonoids, tannins, triterpenoids, and saponins. The antidiabetic activity is evidenced by an effective reduction in blood sugar levels at a concentration of 50%, where the average data for the reduction in blood sugar levels in hyperglycemic mice is 93 mg/dL. The 50% concentration is proven to have the best antidiabetic effect, supported by a more significant reduction in blood sugar levels than the positive control. The findings of this research are expected to serve as the basis for further development of innovative hyperglycemia therapy products.

Abstract

Rhodamine B is a major problem that arises as a result of the development of the textile industry. Rhodamine B is known to be difficult to degrade naturally thus causing a lot of damage, both to the environment and human health such as respiratory tract infection, skin irritation, digestive tract irritation, and eye infection. This study aims to find and determine the type of mangrove root symbiont bacteria Avicennia marina from Panipahan Village that can degrade Rhodamine B. This research is divided into several stages, namely sampling, isolation, purification, characterization of colony morphology, Rhodamine B biodegradation test through the overlay method, gram staining, biochemical tests, and molecular tests to determine the type of bacteria. The results obtained 16 isolates of symbiont bacteria that were successfully isolated from the roots of the Avicennia marina mangrove in Panipahan Village. Of the 16 isolates of symbiont bacteria, only 2 isolates have the potential to degrade Rhodamine B. The results of the biochemical activity test showed positive results in the Catalase, TSIA, motility, and O/F tests on RA5 symbiont bacterial isolates, while the citrate test showed negative results. For RA16 symbiont bacterial isolates, it is known that only the O/F test shows positive results, while the catalase, TSIA, citrate, and motility tests show negative results. The results of bacterial characteristics obtained are that the RA5 symbiont bacterial isolate belongs to the Bacillus circulans type and the RA16 symbiont bacterial isolate belongs to the Bacillus insolitus type. So, it was concluded that there were 2 bacterial isolates of Avicennia marina mangrove root symbionts in Panipahan Village, Riau that were able to degrade Rhodamine B.

Abstract

Germination is a critical phase in seed plants. Germination is vulnerable to drought stress. Apart from external factors, long seed storage can also affect seed viability. The magnetic field is known to positively impact the germination process because it can increase the activity of the α-amylase enzyme. Lumbung Sewu Cantik is a local upland rice variety from Lampung, Indonesia. This study aims to determine the impact of exposure to a magnetic field of 0,2 mT for 11 minutes 44 seconds (M1) in improving the germination of LSC rice seeds given accelerated aging (So) and drought by 20% PEG 6000 (D1). The parameters observed were germination rate index (GRI), mean germination time (MGT), germination index (GI), final germination percentage (FGP), and percentage of abnormal germination (PAG). This research used a Completely Randomized Design (CRD). The experimental units consisted of Sn (normal seeds as control), SoD1, SoM1, and SoM1D1. Each treatment was repeated five times. The data obtained were tested for normality, analyzed of variance, and further analyzed with DMRT at the α = 0,05 level. The results showed that the magnetic field could accelerate germination in the SoM1 treatments based on the MGT parameters. The magnetic field also reduced the percentage of abnormal seedlings in the SoM1D1 treatments compared to those without a magnetic field (SoD1 treatments).
