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 Mendel's fluid medium yielded the highest protease activity of 0.067 U/ml.

Odonata are considered to be good indicators of enviromental health and water quality with itâ€™s presence and diversity in the Jakabaring lake are (Water Ski and OPI). The research location (Water Ski and OPI) untilized by the community as water catchment areas (flood control), recreation and habitat. The Activity in the lake area can affect the benefit of the lake, affecting the quality of the lake waters as a living habitat for animals and plants.However, to describe the diversity of odonata as indicator of the waters in the area of Water Ski and Lake OPI lakes, there is no such thing, therefore the researchers to look at odonata diversity in the area of Water Ski Lake and Lake OPI Jakabaring Palembang-South Sumatera. The location of the study was determined using the purposive sampling method conducted in April 2018. The species found to identified at the FMIPA Animal Taxonomy Laboratory of Sriwijaya University. Sampling in the morning (07.00 â€“ 10.00 AM) and afternoon (15.00 â€“ 18.00 AM). The results of research in the lake area found 2 suborder, 2 families, 11 genere, and 18 species, the total number of all 984 individual species. Odonata species data obtained in the analysis using Past3 software. The diversity index in the Water Ski lake is 1.992 and the diversity index in the OPI lake is 1.758. Diversity index value (2.014), dominance index (0.7922) and evenness index (0.4165). Odonata and enviromental conditions of the lake (Water Ski and OPI) still have relationship, the condition of lake water quality is still below water quality criteria threshold. This is what makes the diversity on both lakes has a moderate value.
