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.

Abstract

Biodiesel (fatty acid methyl esters or FAME) an alternative fuel to substitute diesel oil or diesel fuel made from oils or fats of vegetable or animal. Oils commonly used for biodiesel fuel, among others palm oil. Biodiesel is produced through the transesterification of oils or esterification of fatty acids. The research objective was to determine the quality of biodiesel from palm oil reflux results through the process of esterification and transesterification. Transesterification reaction is the formation of esters and glycerol from trigliserin (fat/oil) with methanol. Transesterification is a type of equilibrium reaction (reversible, where the addition of NaOH catalyst (chemical catalysts) can accelerate the achievement of a state of equilibrium. The results showed that rendamen biodiesel was obtained by 77% and quality parameters that defined American Society for Testing and Materials (ASTM D6751) has meet the standards in terms of density of 0.8654 g/mL, saponification 5.2979 mg KOH /g of oil, iodine number 18.9184 g I2/100g.Keywords: Quality, biodiesel, palm oil

Abstract

Isolation, identification and bioactivity test of nonpolar compunds has been conducted on n-hexane extract sponge Haliclona (Reniera) fascigera of the island Samalona, Makassar, South Sulawesi. Isolation techniques consist of maceration, partition, fractionation using 2 steps using vacuum column chromatography and flash column chromatography and also purification step. Identification of isolate was analyzed with TLC, FTIR, GC-MS, and 1H NMR. The research result was obtained isolate as much as 4 mg and clear solid form. FTIR analysis indicate functional group OH, CH­2, CH3, C=O, =CH and C-O. Identification of spot TLC under UV light and spotting solvent show that the spot was active on UV long and short waves and dark brown with cerium sulphate. The results show that isolate A contain aliphatic and alcohol compounds. Bioactivity test results indicate that these isolate A be able to inhibit the growth of bacteria Staphylococus aureus with inhibition zone diameter were 11.60 mm (100 ppm); 10.40 mm (50 ppm); 9.50 mm (25 ppm); 6.50 mm (10 ppm); 6,60 mm (negative control); 17.40 mm (positive control) and against bacteria Escherichia coli with inhibition zone diameter were 6.70 mm (100 ppm); 6,10 mm (50 ppm); 5,90 mm (25 ppm); 5.85 mm (10 ppm); 5,20 mm (negative control); 18.60 mm (positive control).

Abstract

This research aims to analyze the concentration of metals Fe, Zn, and Cr in protein fractions of sponge Agelas nakamurai from Kapoposang Island, Spermonde archipelago. Protein samples were extracted, fractionated using various saturated ammonium sulphate (SAS) concentration, namely 0-20%, 20-40%, 40-60% and 60-80%, then purified by dialysis using celophane membranes. Each fraction was digested using microwave before metal analysis using ICP OES (Inductively Coupled Plasma Optical Emission Spectroscopy). The results have shown that highest iron concentration was found in 20-40% fraction, 28.2 µg/L, while lowest one was in 60-80% fraction, 2.39 µg/L. For Zn, its highest concentration were found 20-40% fraction,  9.42 µg/L and the lowest one was 40-60%, 3.66 µg/L. On the other hand, the concentration of Cr was found highest at 20-40% fraction, 2.28 µg/L, while its lowest amount was at  60-80% fraction, 0.238 µg/L. In the meantime, its high- est antibacterial activity was at 0-20% fraction examined in Salmonella thypusa with inhibition diameter was 7,00 mm, where the amount of essential metals Fe, Zn and Cr are 17,2 µg/L, 6,32 µg/L, 1,47 µg/L. It was concluded that the essential metals investigated were coexisted and distrib- uted in several protein fractions and its bioactive properties.Keywords   :  Agelas  nakamurai,  Bioactive  protein,  essential  metals, ICP-OES,  Kapoposang Island

Abstract

This research aims to analyze the levels of copper (Cu) in the sponge symbiont bacterial. The research was carried out through the steps of isolation, identification, and measurement of the metal content. Sponges used in this research is of Callyspongia sp. Bacteria were isolated from Callyspongia sp sponges in the Bacillus sp gram-positive. By using Atomic Absorption Spectrophotometer, the results showed that the levels of Cu for Callyspongia sp is 8.9112 ppm, while in the extracellular bacterial isolates Cu level ranging between 1.4009 ppm and 2.0336 ppm and in the intracellular is between 0.4786 ppm and 1.7813 ppm. It is concluded that bacterial isolates either in extra- as well as intracellular were both accomodated copper in their bodies.

Abstract

Chitosanase enzyme is an enzyme to catalyze the bonding endohidrolisis (1.4) β- glucoside on chitosan into a series chitosan oligomers or chitooligosaccarides. Chitosanase of microbes give good results in producing chitooligosaccarides, but very expensive for use in large-scale industry. This study aims to manufacture and characterization of crude chitosanase enzyme from Klebsiella sp used to hydrolyze chitosan into chitooligosaccarides. Chitosanase produced in the fermentation medium containing 0.5% colloidal chitosan for 60 hours with the activity of 0.309 U / mL (5,235 U / mg), work optimally at 40 ° C and pH 8, is stable at pH 6-7, activated by Co2 + ; Ca 2+ and Ni 2+. Chitooligosaccarides obtained in the form of a mixture of monomer to octamer, which soluble in acetic acid 0.25% to 0.5%, having intrinsic viscosity decreases with increasing time of incubation with molecular weight range of 4103.12 g / mol (incubation 1 hour) ; 1483.48 g / mol (incubation 2 hours) and 1065.79 g / mol (incubation 3 hours).Key word : Chitosanase, Klebsiella, Chitooligosaccarides

Abstract

A research on Age Determination of Sea Sediment of Spermonde Islands through Ac- tivity Measurements of 14C with LSC (Liquid Scintillation Counting) method has been performed. The sample of sediment was taken at the island of Lae-Lae, Spermonde Islands where it is rela- tively close to the influence of human activities. This study aims to determine the activity of 14C in the sediment sample and calculate the age through measurement of 14C specific activities of  sedi- ment sample.  Preparation is done both physically and chemically by using a mixture of solution of the acid and alkaline: NaOH, H2O2, HClO4, and HCl to produce sediment sample which was white and clean with a weight reduction of up to 5 %.  Carbonate matrix sample was separated as CO2 using 1 N KOH absorber with H3PO4  85 %. Carbon content of the sample solution is 1.172 g/8 mL.  The 14C activity of the sample was analyzed using LSC (Liquid Scintillation Counting) as an analysis technique. The specific activity sediment sample was 13.85g/C. The age of sediment sam- ple calculated from the specific activity was 821,0822 year.
