This study aimed to assess the potential of avocado seed extract as an antifungal agent and to determine the optimum concentration of avocado seed extract in inhibiting the growth of Colletotrichum. This research used laboratory- scale experimental methods. Inhibition test of extract towards Colletotrichum was carried out using poison food method using following extract concentration 20%, 40%, 60%, 80% and 100% Topsin M Wp 0.2% were used as negatif control. The result showed that avocado seed extract had a significant antifungal activity against Colletotrichum at the consentration of 40%, the effect was emerged since the 4th day of incubation which was observed by measuring fungal growth diameter

Water color intensity is associated with topsoil concentration. The lower color intensity the lower topsoil concentration, pH and temperature. Peat water characteristic were determined by accumulation of Natural Organic Matter. The study was conducted on November 2017 to February 2018 in Health Laboratory of North Sumatera by using 3 samples of peat water to find out characteristics of peat water bacteria. Isolated bacteria were analysed by macroscopic and microscopic examination. The result showed that the bacteria have various morphology and motility. Based on characteristics, sp1 was suspected to be in the group of Staphylococcus genus while sp2 and sp3 were belong to the Escherichia genus.

Vitamin D as an immunomodulator play an important role in controlling glycemic levels and reducing the risk of diabetes. HbA1c as a substance formed from glucose binding with hemoglobin which has a good relationship with average blood sugar levels of fasting, daily and 3 months. This research was conducted to determine the relationship between vitamin D levels and HbA1c in patients with type 2 diabetes mellitus. This research used descriptive methods and the research samples were all patients who suffer from type 2 diabetes mellitus in the clinical laboratory of Thamrin Medan. Data were obtained by checking vitamin D and HbA1c levels in patients blood serum. The number of samples in this research were 47 people. The results of this research indicate that there is a very weak relationship between vitamin D levels and HbA1c, with r = 0,225 and R = 5,1%, therefore, it was clearly presented that effect of vitamin D on HbA1c is 5,1%.

Pests are one of the factors that reduce the production and quality of cultivated plants, for example grayak caterpillars (Spodoptera litura) which attack mustard plants. Grayak caterpillars (Spodoptera litura) can be controlled using chemical compounds (insecticides), can be manually collected by hand and can also be biologically controlled, for example with mushrooms. The purpose of this study was to examine the effectiveness of the fungus Metarhizium anisopliae on Spodoptera litura caterpillar larvae in green mustard plants (Brassica juncea L.). The caterpillar used in this study is the Instar-2 (I₁) and Instar-4 (I₂) phase caterpillars. The concentration of fungi was inoculated were 10-2 (M₁), 10 -4 (M₂), and 10 -6 (M₃), and without fungi as a control (M₀). The design used was Factorial RAL with 3 replications. The experimental results showed that spore density M₁, M₂, and M₃ were quite effective at killing the caterpillar both on instar-2 (I₁) and on instar-4 (I₂

Lactic acid bakteria have characteristics that are able to ferment sugars or carbohydrates and produce lactic acid as the final product of fermentation. The purpose of this research was to isolates the lactic acid bacteria from the digestive tract of tilapia fish and to investigate the inhibitory power produced by lactic acid bacteria in inhibiting the growth of Staphylococcus aureus and Shigella sp. Isolation of lactic acid bacteria was done by using MRSA medium and to see the ability of lactic acid bacteria isolates in inhibiting the growth of Staphylococcus aureus and Shigella sp then used disc diffusion method. The isolates obtained were then characterized by morphology and biochemistry. From the research obtained two lactic acid bacteria that is sp1 and sp2. Lactic acid bacteria sp1 and sp2 are able to inhibit Staphylococcus aureus and Shigella sp with the biggest inhibition to Staphylococcus aureus by sp2 of 8.75 mm and the biggest inhibition of Shigella sp is shown by sp2 that is equal to 7.16 mm. Based on the results of isolation and characterization done in this research can be concluded that lactic acid bacteria of the digestive tract of fish tilapia sp1 and sp2 capable in inhibiting Staphylococcus aureus with a the number of 8.75 mm and Shigella sp with a of 7.16 mm.

Potassium iodide is one of the substances that must be present in iodized salt. The purpose of this research was to determine the level of KIO3 in consumption salts that are circulating in the market by iodometry method based on Indonesia National Standart 01-3556-2016. The results of the reseacrh showed that of the 15 salt sampels, it turns out that 8 salt samples of KIO3 levels meet the SNI standard, which is 30 – 80 ppm, while 7 salt sampels did not meet the SNI Standard. For 7 salt sampels that did not meet SNI standard after testing the moisture content, sodium chloride content and cadmium contamination, only 3 salt sampels of water content meet the SNI standard and 4 sampels of water content did not meet it.For testing the levels of sodium chloride and cadmium contamination, it has met SNI standards.

Sunflowers ((Helianthus annuus L) is a plant that has the ability to absorb metals in polluted soil or environment. This study aims to determine the ability of sunflower plants to absorb lead (Pb) in the soil. This research method use a Completely Randomized Design (CRD). Pb metal analysis was carried out by testing the lrvels using the Atomic Absorption Spectrophotometry (AAS) tool in the Chemical Laboratory (LABKES). The results showed that the highest absorption of Pb contamination in P2L2 treatment (2.0 ppm) as much as 5.04 ppm and the lowest absorption of metals in the treatment P1L1 (0.3 ppm) yielded as much as 0.52 ppm Pb metal content. From the results of these studies it can be concluded that sunflower plants can be used as phytoremediation pf Pb metal.
