Abstract

Minerals, calcium, and iron are needed for humans to stay healthy and active and have various roles in the human body. The purpose of this study was to determine the levels of calcium and iron in SK1, SK2, SK3, and SK4 milk. To compare calcium and iron levels in SK1, SK2, SK3, and SK4 milk. The results of the determination of calcium and iron levels by atomic absorption spectrophotometry showed that there was a difference in the content of calcium and iron in SK3 soy milk (12.178 ± 46, 399 mg/100 ml), SK1 milk (5, 3008 ± 8, 798 mg/100). ml), SK2 milk (9, 8821 ± 55, 676 mg/100 ml), SK4 milk (4, 8634 ± 125, 845). The iron content of SK4 milk is (1.3851 ± 82.709 mg/100 ml), SK1 milk is (0.5501 ± 68.924 mg/100 ml), SK2 milk is (0.6450 ± 50.026 mg/100 ml), SK3 milk of (0.7464 ± 64 mg/100 ml). The results showed that SK3 soy milk contained more calcium than SK1, SK2, and SK4. The results of iron levels showed that SK4 soy milk contained greater iron than SK1, SK2, and SK3 soy milk.

Abstract

Mercury is a heavy metal that can have a toxic effect on the body so it can cause death. Mercury metal contamination in food is regulated in SNI number 7387 of 2009 regarding the Maximum Heavy Metal Limit. Some metal waste disposal ends up in rivers, lakes, or sea waters so that metal pollution can occur in the ecosystem. This study aims to determine levels of mercury metal contamination in seawater fish, including shark, mackerel, salmon, tuna, red snapper, and white shrimp. Sample preparation was carried out by wet digestion method using a microwave digestion device. Mercury analysis was carried out using the AAS (Atomic Absorption Spectrophotometry) method. The wavelength used is 253.7 nm. The results showed that mercury in sharks was 0.2045 ± 0.0099 mg/kg, mackerel 0.4184 ± 0.0297 mg/kg, salmon 0.3848 ± 0.0794 mg/kg, tuna fish 0.3706 ± 0.0674 mg/kg, snapper 0.4088 ± 0.0397 mg/kg, and shrimp 0.4289 ± 0.0813 mg/kg. The results of the analysis showed that of the six samples of seawater fish that had been tested, the maximum metal contamination limit determined by SNI 7387 the Year 2009 was 0.5 mg/kg.

Abstract

Nanogel preparations consist of nanoemulsions and gels, where nanoemulsion is one type of preparation that can increase drug permeability on the membrane surface. The use of cinnamon extract as an antibacterial active substance is because cinnamon (Cinnamomum burmannii) contains saponins, tannins, and flavonoids. This study aims to make nanogel preparations with the active ingredient of cinnamon extract and to determine the antibacterial effectiveness of the nanogel as the active ingredient of the cinnamon extract against Staphylococcus aureus. The manufacture of 2% cinnamon extract nanoemulsion aims to make nanoparticle-sized nanogel preparations and as an antibacterial active substance in nanogel preparations against Staphylococcus aureus bacteria. Nanogel preparations were made by adding cinnamon extract nanoemulsion with varying concentrations of F1(2%), F2(4%), F3(6%), and blank formula (F0) as the basis for nanogels without cinnamon extract nanoemulsion. The results showed that the cinnamon extract nanoemulsion could be made into nanogels to produce a thick, brown-colored gel with a characteristic cinnamon smell. The result of the pH of the preparation is 6 according to the pH of the skin, has good homogeneity, and is not irritating to the skin. The PSA test produces a nanoparticle size of 24.2 nm, and the antibacterial effectiveness test of the nanogel preparation can inhibit Staphylococcus aureus bacteria. Produced a moderate inhibition zone category (6.7-7.1 mm) and the F3 formulation (6%) was the best formulation.

Abstract

Fish containing mercury will have a bad impact on the health of the human body. The maximum limit of mercury levels in fish that has been determined by SNI (2009) on fish is 0.5 mg/kg. This study aims to determine the presence or absence of mercury (Hg) metal contamination in several types of freshwater fish, namely catfish (Clariasgariepinus), catfish (Pangsiushypophthalmus), tilapia (Oreochromis mossambicus), tilapia (Oreochromis niloticus), pomfret (Colossomamacropomum) and giant prawn (Macrobrachiumrosenbergii), by Atomic Absorption Spectrophotometry (AAS). Quantitative analysis of mercury used atomic absorption spectrophotometry (Shimadzu AA-6200). Measured at a wavelength of 253.7 nm. The results of this study were white pomfret containing mercury with levels of 0.2043 -+ 0.0079 mg/kg, catfish containing mercury with levels of 0.4116 -+ 0.1105 mg/kg, catfish containing mercury with levels of 0.4088 -+ 0.1076 mg/kg, tilapia fish contains mercury with levels of 0.4034 -+ 0.1443 mg/kg, tilapia fish contains mercury with levels of 0.4191 -+ 0.0750 mg/kg, and giant prawns contain mercury with levels of 0, 3928 -+ 0.0521 mg/kg. The calculation results show that all types of fresh water fish contain mercury <0.5 in accordance with the requirements set by SNI No.7387 (2009) on fish, namely 0.5 mg/kg.

Abstract

Fresh fruit bunches (FFBs) from oil palms serve as the primary raw material for crude palm oil (CPO) production. Among various quality parameters, the Deterioration of Bleachability Index (DOBI) and carotenoid content—particularly β-carotene—are critical indicators of CPO quality. A higher DOBI value generally reflects a lower concentration of oxidized carotenes, which facilitates the bleaching process, as the color imparted by oxidized carotenoids is more difficult to remove through conventional heating. The samples are CPO were randomly collected from production facilities located in North Sumatra. Range DOBI is 2.27 – 2.66 and range carotene 401 – 492 ppm. Average DOBI is 2.44 is showing that the quality of CPO is fair and can be used to processed as cooking oil.

Abstract

The nutritional value and biochemical properties of oil are measured by the fatty acids composition in oil and the position of fatty acids (sn-1,2,3) in the triacylglycerol (TAG) molecule. The purpose of this study was to measure the nutritional value based on the fatty acids composition of virgin coconut oil (VCO) and palm kernel oil (PKO), and the position of lauric acid in sn-2. The VCO used was VCO obtained from one of the Pharmacies store in Medan, and PKO from the Oil Processing Plant. The total fatty acid composition was measured by Gas Chromatography. The nutritional value of fat was evaluated by the percentage deviation from 33.33% (ratio: 1: 1: 1) of each group of fatty acid (saturated fatty acids; SFA: monounsaturated fatty acids; MUFA:polyunsaturated fatty acid (PUFA). The distribution of lauric acid in TAG was conducted through hydrolysis by using specific lipase enzymes active at sn-1,3 positions, so that free fatty acids and 2-monoacylglycerol were produced from one TAG molecule. Then free fatty acids were determined by Gas Chromatography. The distribution of lauric acid at sn-2 position was the difference between total lauric acid on TAG before hydrolysis and free lauric acid from sn-1.3 position after hydrolysis. The results showed that PKO nutritional value was better because of the smaller deviation (95.29%) compared with nutritional value of VCO with a greater deviation (118.55%). Lauric acid in sn-2 from VCO and PKO showed that the distribution of lauric acid in sn-2 position was not different,48.33and 48.59%. Keywords: virgin coconut oil, palm kernel oil, composition of fatty acids, sn-2 position, lauric acids
