Abstract

Tuberkulosis adalah penyakit infeksi menular, kronik dan dapat menyebabkan kematian yang disebabkan oleh Mycobacterium tuberculosis. Diagnosa tuberkulosis dilakukan dengan berbagai cara, salah satunya dengan kultur pada media Ogawa. Penelitian ini bertujuan untuk mengetahui kecepatan pertumbuhan M. tuberculosis pada media ogawa dengan bahan dasar telur puyuh, telur bebek, telur enthok, dan telur ayam kampung. Metode yang dilakukan yaitu sputum BTA 3+ yang didapatkan dari Balai Kesehatan Paru Masyarakat (BKPM) Semarang diolah dengan metode kubica, kemudian diinokulasi pada media ogawa dengan bahan dasar telur yang berbeda. Pengamatan kecepatan pertumbuham M. tuberculosis dilakukan setiap hari. Hasil penelitian menunjukan ada perbedaan yang signifikan pada ke empat telur terhadap pertumbuhan M. tuberculosis pada media ogawa. Hasil penelitian menunjukkan bahwa media ogawa dengan bahan dasar telur puyuh dan entok dapat menumbuhkan M. tuberculosis lebih cepat dibanding dengan bahan dasar telur ayam kampung dan telur bebek. Media ogawa berbahan dasar telur puyuh dan telur entok menunjukkan rata-rata waktu pertumbuhan tercepat yaitu 17 hari. Sedangkan bahan dasar telur ayam kampung 20-21 hari dan bahan dasar telur bebek 23-24 hari.

Abstract

Noni contains protease enzymes that can hydrolyze proteins by breaking the peptide bond, so it can be used to soften the meat. The purpose of this study was toanalyze protein profile on 3 types of meat (goats, buffalo and cow) before and aftergreased with non-fertilizing powder with 30 minutes immersion. 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 greased with powder of noni. The results showed that in control meat (goats, buffalo and cow) that were not greased with noni powder there were many major protein bands compared with minor protein bands. While on goat meat, buffalo and cow greased with powder of noni with concentration 10% b / b, 15% b / b, 20% b / b and 25% b / b showed different results at each concentration that there were many minor protein bands than the major protein bands. The higher concentration powder of Noni then the amount of protein in the meat is more denatured. Based on these results indicate that the protease enzyme contained in the powder of noni is able to break peptide bonds in meat protein to proteinshaped minor bands (micromolecul).Keyword : meat, noni powder, protein profile, SDS-PAGE

Abstract

The need for protease enzymes in Indonesia and the world continues to increase, requiring  new  protease  sources.  Bacteria  are  beneficial  sources  of  protease because they are easy to obtain and rapidly multiply. Bacterial identification could be done molecularly through analysis of the 16S rRNA gene. This study aimed to obtain an isolate of protease-producing bacterium from 24-h post-fermented red oncom and to identify the obtained bacterial strain molecularly by 16S rRNA gene sequence. The protease production test on bacteria found in red oncom sample was done  using  a  selective  medium,  Skim  Milk  Agar  (SMA).  DNA  genomes  of proteolytic bacterial cells were extracted by Promega KIT. The amplifying process of 16S rRNA gene using the Polymerase Chain Reaction (PCR) method. The amplified  DNA  were  analyzed  using  the  BLAST  program.  The  results  of  the research found 8 isolate of bacterias. The most unique isolate was IROD1.3. It has significant  proteolytic  activity  based  on  the  ability  to  produce  clear  zone  of protease on SMA medium with a diameter of 85,00 mm. Isolate IROD1.3 was identified  molecularly  as  Bacillus  thuringiensis  with  similarity  of  96% to  the sequence of 16S rRNA gene Bacillus thuringiensis strain TERI SID4 (Genbank access code: KX822158.1).

Abstract

Salmonella typhi is a negative basil Gram bacterium that causes typhoid fever. Flagel of S. typhi contain proteins, as locomotor and it can help bacteria to attach on host cells. Haemagglutinin protein is protein that can agglutinate erythrocytes. The goal of this research is to analize S. typhi flagellin proteins haemagglutination activity Based on ABO blood group. Flagellin proteins isolation method of modified Alexan method (2009) and haemagglutination test method of Finkeltein and Hanne method (1982). Haemagglutination result of ABO blood type show that SLT-1 S. typhi flagellin proteins can’t agglutinate human erythrocytes A, B, and O, but it can agglutinate human erythrocytes until 8 times dilution of AB blood type from 50 μg/μl concentration in 50 μl. BA 07.4 S. typhi flagellin proteins can agglutinate human erythrocytes of A blood type until 16 times dilution, 8 times dilution of AB blood type, 4 times dilution of O blood type, and it can’t agglutinate human erythrocytes B blood type.Keywords: Salmonella typhi, Flagellin Proteins, Haemagglutination, Erythrocytes of ABO System.
