The use of hydroxide compounds as CO2 absorbents for Measurement of Carbon-14 in Coral Reef Sample fromSpermonde Archipelago. This research aimed to determine the age of coral reef sample of Spermonde Archipelago by measuring the activity of carbon-14 using the method Liquid Scintillation Counting (LSC). The coral reef sample was collected in Langkai Island. The research was conducted by following steps of sample preparation, the CO2 absorption using the hydroxide solutions (KOH and NaOH). The measurement of the carbon-14 activities was performed using the Liquid Scintillation Counter (LSC) Hidex 300 SL. The research results indicated that the absorption capacities of KOH and NaOH were 0,450 and 0,425 mol CO2/mol hydroxide respectively. The specific activity of coral reef sample using absorbent KOH and NaOH were 14.51; and 14.57 DPM/g C, respectively.The age of coral reef sample, which was calculated based on the specific activity values using the absorbents KOH and NaOH were 436.13; and 403.61years, respectively.

Research on the use of a liquid scintillation counter method in determining the concentration of biodiesel in the market has been carried out by taking samples of biodiesel in Pertamina. Preparation done by creating a standard biodiesel and biodiesel mixed with diesel at a certain concentration. Biodiesel is chemically formed by the transesterification and esterification process is converted into methyl ester triglycerides with the help of H2SO4 and NaOH as a catalyst. Total carbon in the sample solution is 1.5690 g/8 mL obtained through methods spekktrofotometri uv-vis. The method of determining the concentration of a specific activity based on measurements of samples obtained from the shredded Liquid Scintilation Counter (LSC) Hidex 300 SL, ie 11.5902 DPM / gC. By using the specific activity of the sample and the specific activity was added to standard linear equations of the obtained sample concentration of biodiesel amounted to 18.81%.

A research has been on determining the origin of forest honey quality Mallawa Maros based on the levels of 5-(hydroxymethyl)furfural-2-karbaldehida (HMF)is quantitatively based on the variation of heating temperature and duration of storage with White spectrophotometric method. The results showed that the levels of forest honey HMF origin Mallawa on heating temperature 35°C,90°C and 110°C respectively is 42.2023 mg/Kg, 46.0274 mg/Kg and 62.2520 mg/Kg. While the storage duration for 3,4, and 5 months had higher levels of HMF each 27.4309 mg/Kg, 42.5158 mg/Kg and 48.9405 mg/Kg. Heating temperature and storage time a big influence on levels of HMF and show a strong relationship to the water content, pH and free acid, reducing sugar content and diastase enzyme activity. Based on the research results, levels of HMF at the heating temperature of 110oC has passed the standards set by the SNI (up to 50 mg/Kg). Whereas the standard set by IHC for honey originating from thetropics (80 mg/ Kg)

ISOLATION, IDENTIFICATION AND BIOACTIVITY TEST OF NON POLAR COMPOUNDS ON n-HEXANE EXTRACT OF Haliclona (Reniera) fascigera FROM SAMALONA ISLAND-SPERMONDE ARCHIPELAGO Hafiludin Uli; Alfian Noor; Fredryk Welliam Mandey; Ajuk Sapar

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).

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

This study aimed to determine the volatile organic compound for Mallawa honey. The quality of honey is determined from the nectar source, geographic location, and the processing technology. Volatile organic compound is one of the indicators in honey to determine the quality marker and this compound is formation aroma of honey.This research was done in three stages, namely the stage of sample preparation, extraction phase, and phase identification. Stages of sample preparation was performed to determine sampling locations, the determination of the location of the extraction and identification. Extraction is done in analytical chemistry laboratory Science Faculty, Hasanuddin University. Honey samples were extracted with n-heksan. The identification process carried out in an integrated laboratory Department of Chemical Science Faculty of Hasanuddin University, GCMS performed while the data in Forensik laboratory, POLRI. The results were obtained 35 volatile organic compounds, which are grouped into six classes of compounds, namely: hydrocarbons, acid, aromatic, ketones, aldehides and the other compounds
