Abstract

Lipase has a great catalytic power, but easily influenced by environments and difficult to separate at the ends of the reaction, so it can not be re-used. Based on that, one solution to overcome that problem is through the enzyme immobilization. Immobilization of lipase on chitosan powder was performed via cross linking technique. Chitosan was prepared from crab shell with deacetylation degree 82,34% and crosslinked with glutaraldehide. The aims of this research is to determine the thermal stability and multiple-use stability through the hydrolysis reaction of palm oil. Immobilized lipase on chitosan powder was able to maintain its activity at 50 oC, and still can produce free fatty acid as much as 48,55%. The immobilized lipase was also able to maintain its activity after multiple-uses up to five reaction cycles, and still can produce free fatty acid as much as 40,82%.Keywords: lipase, immobilization, chitosan, cross linking

Abstract

Ozone is one of the gases that can be used as a disinfectant to inhibit the growth of Escherichia coli bacteria. Time of exposure to ozone gas is a way used to disinfectEscherichia coli bacteria. The purpose of this study was to observe the number ofEscherichia coli bacteria exposed to ozone gas with exposure time of 5, 10, 15, 20, 25and 30 minutes and ozone gas control. The study sample was Escherichia colibacteria exposed to ozone gas. The results of the number of colonies of Escherichiacoli on CCA media after exposure to 5, 10, 15 minutes of ozone gas were mean 2.5 x106, 1.25 x 106, 0.5 x 106 CFU / ml, and 20, 25, 30 minutes there is no bacterialgrowth. Control or no exposure to ozone gas mean is 9 x106 CFU / ml. The time ofexposure to ozone gas is most effective in killing Escherichia coli bacteria ie at 20minutes.Keywords: ozone gas, Escherichia coli, Exposure time.

Abstract

Lipase is one kind of enzyme that widely use. Lipase has a great catalytic power, but easily influenced by environments and difficult to separate at the ends of the reaction, so it can not be re-used. Based on that, one solution to overcome that problem is through the enzyme immobilization. Pancreaticlipase was immobilized by absorption method in zeolit as solid support. The aim of this reseacrh is to determine the optimum pH of lipase solubility. The activity of immobilized lipase was tested through the hydrolysis reaction of palm oil. The optimum pH for enzyme dissolution was obtained at pH 6 .Pancreatic lipase and immobilized lipase on zeolite can produce free fatty acid as much as17,37% and 7,35% respectively.Keywords: lipase, immobilization, zeolit, absorption

Abstract

Immobilization of lipase on chitosan powder was performed. The aim of this research is todetermine the optimum conditions for the immobilization process. Chitosan was prepared fromcrab shell through continous deacetylation, and crosslinked with glutaraldehyde. Immobilizationof lipase on chitosan powder was studied under the optimum conditions e.i. pH optimum oflipase solubility and deacetylation degree of chitosan. Immobilized lipase on chitosan powderwas tested for the activity through the hydrolysis reaction of palm oil. Continous deacetylationproduced chitosans A, B and C with deacetylation degrees of 81.34% , 90.23%, and 92.80%,respectively. The optimum pH for enzyme dissolution was obtained at pH 6. Optimumefficiency of immobilization on chitosans A, B, and C, were 47.67; 40.74 and 38.76%,respectively. Specific activity of free lipase, immobilized lipase on chitosan A, immobilizedlipase on chitosan B and immobilized lipase on chitosan C were 23.94; 0.0435; 0.0178; and0.0175 U/g, respectively.Keywords: lipase, immobilization, chitosan, cross linking

Abstract

Telah dilakukan pemeriksaan kadar zat organik dan kadar oksigen terlarut pada air sumur di kelurahan Tanjung Mas Semarang  pada saat pasang dan surut air laut.  Tujuan dari penelitian untuk mengetahui pengaruh pasang dan surut air laut terhadap kadar zat organik dan oksigen terlarut pada air sumur di kelurahan Tanjung Mas Semarang. Sampel penelitian menggunakan air sumur yang diambil dari lima sumur warna yang terdekat dengan air laut. Penetapan kadar zat organik ditetapkan dengan metode permanganat dan kadar oksigen terlarut ditetapkan dengan metode iodometri. Dari hasil penelitian  diperoleh kadar zat organik pasang berturut-turut 33,26 mg/L; 32,38 mg/L; 26,25 mg/L; 20,17 mg/L dan 18,95 mg/L dan surut 44,99 mg/L; 88,84 mg/L; 33,35 mg/L; 25,63 mg/L dan  22,86 mg/L.

Abstract

Papaya leaves contain protease enzymes (protein decomposers), namely papain and kimopapain. Both of these enzymes have the ability to break bonds in protein molecules so that proteins break down into polypeptides and dipeptides. If working on the meat can be decomposed so that the meat becomes tender. The purpose of this study was to determine protein profiles in three types of meat before and after smeared with papaya leaf powder with 60 minutes of immersion. The protein profile of three meat types was analyzed using the SDS-PAGE method. The design of this research is descriptive research with the object of research are goat meat, buffalo and cow covered with papaya leaf powder. The result of this research shows that there are meat of buffalo, goat and cow there are many major and minor ribbon, while in buffalo meat, goat and cow which has been smeared with papaya powder there are many minor protein bands. These results indicate that papain enzyme contained in papaya leaves are powdered to break peptide bonds in meat proteins to proteins in the form of minor bands (micromolecules) and show that the higher concentration of papaya leaf powder the more denatured the protein that is on 20% concentration has only 3 protein bands.Keywords: Meat, Papaya Leaf, Protein Profile, SDS-PAGE
