When the first time appeared in 1999, Marina Chimica Acta was introduced as trilingual journal meaning that we can accept to publish articles in any kind of three languages such as bahasa Indonesia, English, and French. Starting April 2017, however, the publication has been made in English only, no more in bahasa Indonesia nor in French. Currently, Marina Chimica Acta is an international medium and occasional reviews of the publications of original studies (research papers) and occasional reviews in the field of marine chemistry. The journal will endeavor to cover all aspects, from chemical processes to theoretical and experimental work, and by providing a central channel of communication, to speed the flow of information in rapidly expanding disciplines. Submitted paper should be written in English.

UTILIZATION OF ETHANOLAMINE AS CARBON DIOXIDE ABSORBER FOR Asdiana Irma Yusuf; Muhammad Zakir; Maming Maming
Marina Chimica Acta Vol. 16 No. 1 (2015): Enzyme from Bacteria and Coral Age
Publisher : Hasanuddin University

Utilization of ethanolamine as carbon dioxide absober for estimating of coral age from langkai island via LSC (Liquid Scintillation Counting) method has been done. Focus is to analyze coral reefs taken from Langkai island surface which is relatively far from the influence of human activities. Chemical preparation was carried out by using a mixture of NaOH with H2O2 30% followed by a mixture of HClO4 with H2O2 30%, and finally with HCl solution to produce a clean sample with 8.6% weight reduction. Carbonate matrix samples as CO2 is produced by reaction with HCl 10% and absorbed by ethanolamine solution 30% as carbamate complex. The total carbon in the sample solution is 4.542 grams obtained through decreased method after and before absorbtion process. Total carbon in 8 mL sample is 0.2477 grams. Radiocarbon dating method based on the measurement of the specific activity of the samples acquired from the result of LSC (Liquid Scintilation Counter)Hidex 300 SL counting. Age of coral reefs was counted from specific activities data and average activities of modern carbon by using radioisotope decay rate formula. The spesific activities of 14C in coral reefs from Langkai island is 14.55 ± 1.1 dpm/gC. Finally the age of coral reefs was estimated 415.01 ± 91.08 years.Keywords: Coral reefs, LSC (Liquid Scintilation Counting), radiocarbon dating, Spermonde islands.

Coral reef sample of the island Barrang Lompo at coordinates 5 ° 06 '49 " LS 119 ° 25' 20" BT with a dept of 3-4 meters from the sea surface. Coral reefs (coral reef) is an ecosystem that live on the water in the form of limestone formations (CaCO3). Sample preparation is done physically and chemically. Chemical preparation of coral reef sample was using 30% H2O2 continued with HClO4 mixture and H2O2 30% and the last with a solution of HCl to produce a clean sample with a weight reduction of 16.318%. Carbonate samples separated as CO2 by reaction with 10% HCl and absorbtion by diethanolamine to produce carbamate compounds with 62.236% efficiency. Total carbon in the sample solution is obtained through a 1,709 gram reduction methods before and after absorption. Radiocarbon dating method is based on measuring the specific activity of the samples obtained from the results of the count Liquid Scintillation Counting (LSC) Hidex 300 SL, which is 7.938192 dpm/gC. The specific activity of the age of the coral reefs are estimated 5425.452 year

Research on the phenomenon of climate change on the region Makassar Strait waters that are part of the oceanographic activities that require observation of the sea surface temperature (SST), surface currents and ocean color imagery from satellite imagery. In this case, satellite remote sensing data using Aqua-Modis analyze both visually and raw-surface temperature parameter data in order to study a variety of other related phenomena that take place in the ocean. The existence of satellite imagery data for the observation of parameters and / or oceanographic phenomena will be more profitable in terms of time and cost and high accuracy. The purpose of this study was to review based on the description of the SST analysis using Aqua-Modis image data (non-commercial) and open source software in providing the information cepatdan applicable. Bodies Spermonde been considering the seas is quite unique because it is located right in the path of the current meeting of the Pacific Ocean through the sea of Sulawesi and spacious enough for the continuity of mesoscale oceanographic processes for coverage in the waters Spermonde in (islands) Indonesia

Honey is a sweet liquid that comes from the nectar of plants that are processed by bee. The composition of minerals in honey is an important factor in determining the quality of honey because it can affect the properties of bio-chemical physics honey. This research investigated the essential minerals concentration (Cr, Zn, and Mn), as well as the properties of bio-chemical physics. Three samples were collected from different location in the district Kindang is, Kindang, Pattallassang and Oro Gading. Honey samples were analyzed for essential micro mineral Chromium, Zinc and Manganese by using instrument ICP-OES and also analyzed for common bio-physicochemical parameters like moisture content, acidity, ash, pH, conductivity, protein, fat, carbohydrate and calorie. Ranged concentration manganese content of honey from 0.05 to 0.07 mg/mL0,05-0,07 mg/mL and concentration of chromium ≤0,1 ng/mL-0.22 mg/mL, whereas the concentration of zinc is below the limit detection tool that is ≤0,1 ng/mL. The average value of the quality of honey Kindang districts is 19.69% water content, ash content of 0.26%; DHL 0.36 mS/cm; 22.06 acidity meq/kg; pH 4.43; protein of 7.19% (w/w); 0.1301% fat. Total carbohydrate is 72.55%; calories 320.3101 cal; and energy 1340.2289 KJ. The results of this study indicate that manganese has the highest concentration in all samples of honey and showed tah hhoney from Kindang district have the a good quality according to national and international standar of honey
