Indonesia is the second largest country after China in terms of capture fisheries production. Capture fisheries production in Indonesia in 2016 reached 6.83 million tons with a value of Rp. 125.3 trillion. The abundant fishery potential causes the fish preservation process at the fishermen level to be constrained. The limited number of preservatives that are safe for food makes formaldehyde an alternative preservative. The use of formaldehyde in food can cause poisoning to the human body.In the formaldehyde test conducted by the Integrated Supervision Team of the Aceh Marine and Fisheries Service (DKP) in 2017 it was found that the practice of using formalin as a fish preservative was still used by some fishermen and fish traders in Indonesia. Aceh. This research was conducted to determine the sustainability of the practice of using formaldehyde by fishermen and traders by identifying the formalin content in tuna and mackerel in Idi Rayeuk Fish Landing Port, East Aceh Regency. The samples used in this study were 3 tuna and 3 mackerel fish taken randomly at the Idi Rayeuk Fish Landing Site, East Aceh. The results showed that all samples tested showed negative results or the fish did not contain formaldehyde. This shows that the public and fishermen's awareness of the dangers of formaldehyde is very good.
Henna leaves are often used as traditional medicine, including as an antibacterial. Henna leaves contain several active components including phenols and flavonoids which act as antibacterial. The purpose of this study was to determine antibacterial activity of ethanol extract of henna leaves (Lowsonia inermis L.) against Staphyloccocus aureus. This research was conducted using descriptive method. In this study, ethanol extract of henna leaf was made by maceration method. Ethanol extract of henna leaves was tested against Staphylococcus aureus on Nutrient Agar (NA) medium using well diffusion method with 3 extract concentrations, namely 40%, 50% and 90%, tetracycline as positive control and aquadest as negative control with 3 repetitions each. The results of this study showed that inhibition zone diameter of henna leaves extract at a concentration of 40% was 21.29 mm, at a concentration of 50% was 23.1 mm and at a concentration of 90% was 24.4 mm, positive control was 27.93 mm and negative control did not show inhibition zone. The inhibition zone for all concentrations belongs to strong inhibition category.
Purple sweet potato leaf (Ipomoea batatas L.) is one of the plants that has begun to be used as a traditional or herbal medicine. This study aims to determine the content of secondary metabolites from purple sweet potato leaves. This research was conducted at the Chemistry Laboratory, Faculty of Tarbiyah, State Islamic University of Ar-Raniry Banda Aceh with laboratory testing methods. Purple sweet potato leaves were extracted by maceration using 5 L 96% ethanol for 5 days and evaporated in a vacuum rotary evaporator to form a thick extract. Furthermore, phytochemical screening tests were carried out. The test results stated that purple sweet potato leaf extract contains Alkaloids (+++), Flavonoids (+), Tannins (+), Saponins (+), Terpenoids (+), and Steroids (+).
Sodium Cyclamate is one type of sweetener that is permitted, although being allowed to use excess sodium cyclamate can lead to cancer formation. Long-term consumption of sodium cyclamate can lead to metabolism of sodium cyclamate into cyclohexilamine compounds. The purpose of this study was to determine how much sodium cyclamate is used, whether it exceeds the maximum limit of 500 mg / kg weight of the material that has been determined. The sample used was a sample of sugarcane juice sold in Darussalam, which was then examined at the Chemical Laboratory of UIN Ar-raniry and FKIP Kimia Unsyiah Banda Aceh. The analytical method used is quantitative analysis using the UV-vis spectrophotometry method to determine the sodium cyclamate level. The results showed that the 4 samples used were negative containing sodium cyclamate with the level of Sample I = -449.8 Sample 2 = -426.4 Sample 3 = -520.6 Sample 4 = -444.8.
Indonesia is a rich country in terms of flora and fauna diversity. Indonesia's wealth with various types of flora is a highlight for science, one of which is the gotu kola herb (Centella asiatica (L) Urb). The chemical compound asiaticoside is part of the triperoids contained in the gotu kola herb which has the potential as antibacterial, antifungal, antioxidant and anti-cellulite on the skin, suitable for topical preparations such as gels. This study aims to formulate a gel preparation from the ethanolic extract of the gotu kola herb (Centella asiatica (L) Urb) which meets the requirements of a good gel. The formulation of the gel preparation was carried out with concentrations of 20%, 25%, and 30%. Extracted by maceration method using 70% ethanol and in a vacuum rotary evaporator to obtain a thick extract. Evaluation of the gel preparation was carried out by organoleptic test, homogeneity test, pH test, dispersibility test, adhesion test and irritation test. The results of the evaluation carried out with the three concentrations met the requirements of the organoleptic test, homogeneity test, pH test, adhesion test and irritation test, but the ethanol extract gel of the gotu kola herb at concentrations of 20%, 25% and 30% did not meet the requirements for the good dispersion test
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
