Abstract

Triticum aestivum L is a cereal plant that grows optimally in a subtropical climate. In tropical climate wheat growth experieces various obstacles such as high air temperature and humidity, and intensity of light. Study of wheat conditions for the growth of this plant in tropical areas such as Indonesia is needed. This study aims to determine the effect of light on the germination, growth, and early development of wheat.this is an experimental research with two treatments, the first group was in normal light and the the second was without light. Each treatment was carried out using 30 replications. The analysis was carried out by comparing the average value of plant length and plant morphology from eight days of observation on two kinds of treatments. The results showed that there were differences in plant height in the two treatments. The average plant height on the 8th day in normal light treatment was 9.76 cm, while the average plant height with the treatment without light was 10.1 cm. Observations of growth on the morphology of wheat plants showed that plants with no light treatment experienced a slowdown in the opening of the second leaf, had a paler color and thinner leaf blades, compared to plants grown with light treatment. The absence of light accelerates the germination process and increases the height of wheat plants, but at a later stage it can slow down the development of these plants.

Abstract

The purpose of this study was to determine the methanol extract of snail gonggong (Strombus turturella) and the inhibition of methanol extract of gonggong snail meat (Strombus turturella) against the pathogenic bacterium Vibrio alginolyticus. The study used a completely randomized design. The treatment was giving the extract of snail gonggong meat with concentration of 100%, 50%, 25%, positive control using amoxcillin and negative control using distilled water with three replications. The identification of bioactive compounds included alkaloids, saponins, flavonoids, steroids and triterpenoids. The antibacterial activity of the methanol extract of snail gonggong meat (Strombus turturella) was tested by the diffusion method at concentrations of 100%, 50% and 25%. The data collected is then analyzed descriptively qualitatively. The results showed that the antibacterial activity of the 100% concentration of the methanol extract of the gonggong snail meat had moderate inhibition against Vibrio alginolyticus (diameter 7,833 mm). while the concentrations of 50% and 25% did not have an inhibition zone. The identified bioactive compounds included alkaloids, saponins, flavonoids and steroids, while the terpenoid and phenolic compounds were not identified. Thus, the methanol extract of gonggong snail meat has antibacterial potential that can be used to overcome the attack of pathogenic bacteria.

Abstract

The cherry plant (Muntingia calabura L.) is a shrub or small tree only up to 12 meters high, although generally only around 3-6m. The purpose of this study was to see the application of cherry leaf extract to mice infected with Salmonella typimirium. This research is a laboratory experimental study with a post test-only control group design using Balb/c mice as the research object. This research was conducted from 10 February to 15 April 2022. The extract of cherry leaves was used at the basic biology laboratory of Pattimura University. The mice used were adult male mice aged 3 months and weighing about 20 grams. Macrophage analysis was measured from the spleen of mice using the SPPS 20 One Way Anova test and then continued with the LSD follow-up test. The results of the study showed that in the control group the average weight of the spleen was 0.126 lighter because it was not infected with Salmonella typimerium compared to the treatment of cherry leaf extract infected with Salmonella typimerium) dose of 15 mg/kgbw (0.556), dose of 75 mg/kgbw (0.516) and a dose of 150 mg/kgbw (0.510). While there was no significant difference in macrophages. Salmonella typimurium infection will initiate an inflammatory response at the site of spread of the bacteria, including reaching the spleen and causing enlargement of the spleen.
