Abstract

One of the commonly used stains in bacterial identification is gram staining, this staining is used to distinguish the physical properties of the cell wall and the chemical properties of bacteria, this dye will distinguish bacteria into gram-positive bacteria with the result of the bacteria will be purple and gram negative with the result of red bacteria. The use of safranin is effective in working on bacteria because it is alkaline, this can cause binding between the chromophore component in the dye and the cytoplasm of bacteria that are basophilic. However, the use of safranin also has a negative impact on health and the environment. Therefore, the need to use materials that are safer for health and the environment, miana leaf juice (Coleus Scutellarioides (L) Benth) can be used as a natural dye to replace safranin. Minana leaves are very easy to find in gardens and are usually ornamental plants, the anthocyanin content in this plant can be used as a color pigment to replace safranin, anthocyanins will produce red to dark red pigments in an acidic atmosphere. The purpose of this community service activity, the community service organized a workshop for students of the Medical Laboratory Technology Study Program, Lubuk Pakam Medical Health Institute, aiming to provide information on the use of miana leaf juice (Coleus scutellarioides (L) Benth) as an alternative to safranin dye in bacterial gram staining. From the results of the service, it can be concluded that the participants can understand the material and the demonstration, this can be seen from the increase in the percentage of understanding both from before 61% to 87% after being given the demonstration and material.

Abstract

Protease enzyme is an enzyme that is important in protein breakdown. Animals, plants as well as microorganisms such as bacteria can produce this protease enzyme. In its application protease enzymes can be used in the pharmaceutical industry, detergent industry, skin products as well as food products. Tempe is one of the traditional food products that have been known for a long time, tempeh is made from soybean seeds fermented by mushrooms. Molecular identification can use polymerase chain reaction (PCR) method, PCR is the process of multiplying a certain nucleotide sequence using enzymatic processes in vitro. The presence of protein content in tempeh can be possible the presence of bacteria that can break down proteins in the tempeh, especially tempeh that has been fermented about 48-72 hours. Based on the results of characterization and identification of 5 isolates of tempeh post-fermentation 72 hours, positive results of protease enzymes found in isolate TPLP-1, TPLP-2 and TPLP-5, with the largest zone diameter in isolate TPLP-2 50 mm, then isolate with the highest protease enzyme activity isolate TPLP-2 molecularly identified by identifying the gene 16S rRNA which is subsequently included in the BLAST program and obtained by isolate TPLP-2 identified as Pseudomons stuastzeri.

Abstract

Background: Cervical cancer is one of the second-highest sexually transmitted diseases in the world, accounting for 13% of the total 22% of deaths caused by non-communicable diseases. Today there have been many developments about cervical cancer diagnosis methods especially in early detection aimed at recognizing cervical cancer at an earlier stage, including molecular biology detection using PCR tools and electrophoresis. Objective: To identify the results of DNA electrophoresis in vaginal mucosal swabs with cervical cancer. Method : The research method used is experimental. Results: Based on the results of a study using a documentary gel, 2 samples of HPV DNA tape were detected, it was tested positive because there was 450 bp DNA tape and 4 samples of negative results were obtained. Conclusion: The frequency distribution of respondents from 6 samples by using electrophoresis and focumerary gel as readers detected 2 positive samples. A positive result is expressed if a result in the documentary gel is found to be a DNA band. The size of the DNA ribbon produced with the DNA marker markers is at 450 bp, according to the sample target. This shows that the DNA bands in the sample are about 450 bp in size.
