Abstract

Indonesia is an archipelago that is rich in natural marine potential. One of the provinces in Indonesia that is rich in natural marine potential is Aceh. Aceh, which is rich in seaweed, has good prospects to improve the economy of its people. One of the seaweed cultivated in Aceh is Eucheuma cottonii, which has carrageenan content. In the process of carrageenan processing from seaweed alkali is needed which aims to produce carrageenan granules. Precipitation of carrageenan was carried out by heat extraction method which varied alkaline solvents namely NaOH and KOH and than do FTIR and SEM analysis. From the results of FTIR in the absorption area of ​​1010-1080 cm-1 showed the absorption of glycosidik bonds and at 849-850 cm-1 uptake was absorption from galactose-4-phosphate bonds. In wavelength is a type of carrageenan kappa. SEM results show different and uneven carrageenan surfaces.

Abstract

The synthetic dyes Rhodamin B and Methanyl Yellow are still often added to snacks to make the colors of snacks more obvious and people are interested in consuming them. Its use in long-term food products can cause cancer. The purpose of this study was to analyze synthetic dyes in chips, red macaroni, steamed cakes, yellow macaroni, bread jam and guava juice around the Ketapang area of ​​Banda Aceh City. The research method used is the Spot Test Analysis conducted qualitatively at the LPPOM MPU Laboratory in Banda Aceh City. The test results on the three samples namely chips, red macaroni, and steamed cake did not produce a color change reaction that showed Rhodamine B. The test results on yellow macaroni, bread jam and guava juice showed that the three samples tested did not produce a color change reaction indicating the presence of Methanyl Yellow. The conclusion from this test is that snacks have not been identified as Rhodamin B and Methanyl yellow or are free from the contents of the two synthetic dyes.

Abstract

This study aims to determine the analysis of the quality control of palm oil quality in PT. Lembah Bhakti Aceh Singkil Plantation. The function of implementing quality control is to control the quality of the initial input in the form of completion of raw materials, the production process, to the process of output of finished goods. This study uses several methods, namely filtration and titration. The average quality of palm oil at FFA levels ranges from 3.39 to 4.97 with a max.3 standard, a moisture content ranging from 0.12 to 0.3% with a max standard. 0.2%, and impurities levels ranged from 0.015-0.025% with the max standard. 0.02%. Based on the results of the study it can be concluded that the measurement of quality control that is carried out is very influential in product quality, so that it can affect the income. Where the income of a company depends on the CPO oil selling price in PMKS PT. Perkebunan Lembah Bhakti. The selling value in marketing is very dependent on the quality of the CPO.

Abstract

This study aims to determine the quality of RBD olein produced by PT. PHPO according to the peroxide number which refers to SNI 01-3741-2002. The sample used is a yellow liquid fraction obtained by fractionation of RBD palm oil or crude palm oil CPO which has undergone a refining process. The sample was analyzed using the iodometric titration method. The results of the calculation of the average peroxide number of RBD olein oil is 0.282 mg O2 / 100 g. Based on these data, Olein RBD oil meets the company quality standard and SNI 01-3741-2002.

Abstract

Seaweed Gracilaria sp. is a water plant which is included into the red algae group (Rhodophyceae) which can potentially reduce the grade of metals Pb and Cu concentration. This research is aimed to know the heavy level of Pb and Cu metals which is adsorbed in seaweed Gracilaria sp. and the effect on the adsorption power of Pb and Cu metals based on variations in time of contamination. This research was done destructed by refluks destruction with resolvent HNO3: HClO4 (2:1) 15 mL. Thetime variations were 1, 2 and 3 weeks. The solvent of destruction obtained was measured by AAS (Atomic Absorption Spectrophotometer). The results are the grade of Pb metal on seaweed in the initial status concentration is obtained 1,2344 mg/L, 1,2820 mg/L in the first week, 1,2642 mg/L in the second week and 2,3149 mg/L in the third week. Based on the findings, it can be concluded that the grade levels of Pb Metal in seaweed Gracilaria sp. has already passed the BPOM No. 23 of 2017 standards setting is 0,20 mg/L. In the other hand, the grade levels of Cu metal on seaweed in the initial status concentration is obtained 0,0001 mg/L, 0,1579 mg/L in the first week, 0,5120 mg/L in the second week and 0.7946 mg/L in the third week. Based on the findings, it can be concluded that the grade level of Cu metal on seaweed Gracilaria sp. has already passed the limit which is conditioned by BPOM No. 03275/B/SK/VII/1989 is 0,1 mg/L.

Abstract

Water naturally contains various minerals, one of them is fluoride ion. Fluoride in water with suitable amounts give good benefits for health, but give the opposite result in excessive amounts. The purpose of this study was to determine the levels of fluoride contained in bottled drinking water and some well water samples in Banda Aceh. The fluoride amount in bottled drinking water and the well water was analyzed using UV-Vis Spectrophotometry at 570 nm wavelength. The measurement results show that the six samples have fluoride ion levels below 1 mg/L. This proves that the water is suitable for consumption and use because it meets the quality standards of SNI 01-3533-2006 (maximum 1 mg/L for bottled drinking water) and the Health Minister Regulation of Republic Indonesia Number 32 Year 2017 (maximum 1,5mg/L in water for hygiene and sanitation purposes).

Abstract

Heavy metals are compounds that have high toxicity and can cause serious health problems for humans and pose a serious threat to the sustainability of the ecosystem. Prokaryota microorganisms and eukaryotes have the ability to process bioremediation of heavy metals in the environment. Marine fungi as eukaryotic microbes that have high species diversity. The ability to live in marine fungi is influenced by environmental factors that differ from the terrestrial environment such as temperature, pressure, and salinity. Marine fungi have a characteristic structure of metabolites and their ability to bioremediate heavy metals in various processes, namely bioaccumulation, biomineralization, biosorption, and biotransformation. Bioremediation of heavy metals by marine fungi is related to the composition of cell wall structures that have many crosslinking polysaccharides (chitin, chitosan, glucans), glucuronic acid, galactosamine, a small amount of glycoprotein, together with melanin and phenolic polymers containing phenolic units, peptides, fatty acids, which provides quite a lot of oxygen-containing groups such as carboxyl, carbonyl, amino, hydroxyl, phosphate, methoxy and mercapto which are potentially metal binding sites.
