Abstract

Celery fraction research (Apium graveolens L.) was carried out to determine the ability of the sedation effect of celery fraction compared to celery extracts which have been known to have the ability to effect the previous sedation. This study aims to find out which fraction has the best sedation effect. This study was an experimental study with a Completely Randomized Design (CRD) consisting of 5 treatments and 5 replications. Test animals divided into 5 treatment groups namely negative control group (CMC Na 1%), celery extract group 200mg /kg and 3 treatment groups n-hexane fraction, ethyl acetate, and methanol water fraction with a dose of 200 mg /kg . The sedation effect test was carried out using the Traction Test and Fireplace Testmethods. Quantitative data observed were the length of time the mice fell and the length of time the mice went out of the heated tube/glass. The results of the analysis showed that the celery fraction had a better sedation effect than the extract, and the methanol water fraction 200 mg/kg was the most effective fraction in causing sedation effects.

Abstract

This research was purposed to understand the effect of 0.2mT magnetic field exposure treatment for 10 minutes toward medium components to the production of protease in Bacillus sp. That magnetic field exposure treatment was given to 8 medium components namely Milk, Yeast, NaCl, KH2PO4, MgSO4, (NH4)2SO4,Agar and Aquadest. Data from Qualitative Proteolytic Activity test on Bacillus sp. indicated that in all treatment, the bacteria were able to produce the enzyme. The highest Proteolytic Index (IP) from all those treatments came from the magnetically exposed KH2PO4 which was 7.17 at the 10th incubation hour. Treatment of exposure to magnetic fields is also given to the liquid medium. Quantitative data of enzyme activity showed that the best incubation time of protease production by Bacillus sp. is the 24th incubation hours with result of 0.031 U/ml. Exposure of 0.2 mT magnetic field for 10 minutes to the NaCl component in Mendels fluid medium yielded the highest protease activity of 0.067 U/ml.

Sampling of microalgae was conducted in the swamp land of Ogan Ilir regency, South Sumatera in January 2017. Determination of sampling point was done by looking at the presence and abundance of microalgae in the sampling location.  1 L of water sample were taken using a 30-50 μm plankton net. The method which was used in this sampling is purposive sampling method. The samples were grouped into 3, they are culture 1 (B1) derived from a rice cultivation area, culture 2 (B2) derived from a land which was not planted by rice, and culture 3 (B3) derived from swamp water which was not planted by rice. The cultivation of microalgae was using Johnson medium with minimum initial density of 2 × 106 mL-1 cells, then grown up to 16 days. The calculation of cell number and measurement of ammonium concentration were performed on day 1, day 4, day 8 and day 16. Three species of Cyanophyceae class microalgae from the swamp land was found, they are thread algae, Synedra sp., and Melosira sp. Those microalgae may contribute available nitrogen in ammonium form for maximum rice plants on days 10-12 in number of 21.41 μg mL-1. Microalgae in culture 1 can contribute the need for nitrogen for rice plants in the form of ammonium in number of 16.23% - 48.71% with cell density of 7.48 cells mL-1.
