Extraction of chemical content from srikaya leaves (Annona squamosa Linn) was elaborated by maceration method using ethanol 50%, 70% and 90% ethanol. The compounds were analysed using UV-Vis spectrophotometry to determine the tannins compounds in the sampel extracts. The study results obtained the levels of tannins of srikaya leaves (Annona squamosa Linn) from ethanol extract of 50%, 70% and 90% by 14,67 mgGAE/g: 10,34 mgGAE/g: 9,90 mgGAE/g. the most optimal concentration of ethanol solvent for extracting the tannins of the leaves of srikaya (Annona squamosa Linn) is 50% of ethanol</em></p> Copyright (c) ISM Identification and Distribution of Polycyclic Aromatic Hydrocarbon Pollutants in Coastal Ecosystem the Marine Tourism Area, South Sulawesi 2022-05-09T00:31:32+00:00 Ismail Marzuki Nur Rahmi Putri Lubis Irham Pratama Noviar Nurdin Kasim <p>Today's marine tourism is experiencing rapid growth to meet the global needs of the world's population. Exploitation of marine biological wealth is no less important because it involves human life. The marine ecosystem must be of high quality and free from exposure to toxic pollutants, such as PAHs. The marine ecosystem must be of high quality and free from exposure to toxic pollutants, such as PAHs, microplastics. This research aims to provide data and information about the types and abundance of aromatic hydrocarbon compounds in sediments, sea water and marine biota around KKI waters. The analytical method to meet these objectives uses GS/MS. The status of marine tourism areas, especially around KKI waters, is declared polluted by PAHs. The types of PAHs identified in each sample at the three sampling stations were dominated by naphthalene (NL), phenanthrene (PT), pyrene (PR) and azulene (AZ). The average total abundance of PAHs in sponge samples (±70.51%), sediments (±67.30%), followed by seawater samples (±64.85%), starfish samples (±41.80%) and fish (±26.74%). The NL type PAHs were found in all types of samples and at all stations, where the PAHs were thought to originate from industrial, hospital, and household activities. The status of marine tourism, especially around the KKI waters, for tourists needs to be careful and alert, because the KKI area is not completely free from harmful and toxic pollutants, so it is a risk to health. Makassar City TMA managers are encouraged to make efforts to reduce the rate of increase in the concentration of regional PAHs, such as providing periodic data and information about harmful pollutants, education for every tourist to care about waste and planting coastal plants such as mangroves which have a biofilter function against toxic pollutants.</p> Copyright (c) Concentration CONCENTRATION OF MICRONUTRIENTS (Fe, Cu, Mn) IN COCOA PLANTATION LAND IN TRANSMIGRATION AREA, EAST LUWU REGENCY 2022-03-28T03:43:37+00:00 Yunita Pare Rombe <p>Micronutrients such as Fe, Cu, and Mn function to help maintain land productivity, improve soil fertility that has been lost, and increase crop production. Micronutrients are also required for metabolic activity and growth in cocoa plants. Therefore, it is necessary to pay attention to the micronutrient content in the soil where cocoa plants grow. The purpose of this study was to determine the content of micronutrients (Fe, Cu, and Mn) in regional plantation soils. The analysis method uses Inductively Coupled Plasma. The results showed that the micronutrient content in cocoa soil with 5 locations was Iron (Fe), Copper (Cu), and Manganese (Mn) with an average of 1056.050 mg/100g; 3.816 mg/100g; and 53.350 mg/100g.</p> Copyright (c) The role oxygen in packaged drinking water (PDW) and its relation to the increase of human life quality 2022-03-22T11:50:09+00:00 Harningsih Karim <p>Oxygen is one of the chemical elements that play an essential role in human life. The human cannot sustain their life without oxygen. In the breathing system, human inhales the air that contains oxygen. Water obtained from the earth is formed by a reaction of one oxygen atom and two hydrogen atoms. Such water is involved in the life cycle of organisms. Water supports the growth and enlargement of the body among all organisms. Packaged drinking water (PDW) can be drunk directly through a hygienic process. Oxygen in the human body is linked to the ferrous element in haemoglobin and then transported throughout the human body. Therefore, people feel fresher while they drink cold water because, in the cold water, the dissolved oxygen is available in the maximum amount. The purpose of this review paper is to explore the role oxygen in PDW and its relation to the increase of human life quality.</p> Copyright (c) Optimization of FeSO4 Molarity for Synthesis of Prussian Blue Pigment from Iron Sand from Sunur Beach Estuary, Pariaman 2022-02-22T06:25:10+00:00 Nafis Sudirman <p>The objective of this research was to see how the molarity of Iron(II) sulfate (FeSO<sub>4</sub>) solution affected the coloring of the Prussian blue pigment produced, to find the best synthesis conditions. The coprecipitation methods were used to synthesize Prussian blue from FeSO<sub>4</sub> and K<sub>3</sub>[Fe(CN)<sub>6</sub>] solutions. The molarity of iron(II) sulfate (FeSO<sub>4</sub>) was varied to 0.005 M, 0.0025 M, and 0.00125 M in this research, with the resulting products referred to as K1, K2, and K3. The UV-Visible spectrophotometer was used to analyze the produced pigment. The molarity of Iron(II) sulfate (FeSO<sub>4</sub>) impacts the final Prussian blue pigment, as observed in the experiment with variations in the molarity of FeSO<sub>4</sub>. The optimum color of Prussian blue, with a peak near-standard UV-Visible spectra at 686 nm, was produced at 11.85 mM FeSO<sub>4 </sub>molarity, which was very much by the standard absorbance wavelength Prussian blue pigment.</p> Copyright (c)
