Abstract

Escherichia coli O157:H7 and Staphylocccus epidermidis are bacteria that can cause disease in humans. Alternative control efforts are very important because the use of antibiotics can cause adverse side effects. This study aims to obtain extracts of white galangal (Alpinia galanga L.) in inhibiting the growth of E. coli O157:H7 and S. epidermidis. In this test, white galangal extract was macerated with three solvents at different polarity levels (96% ethanol, n-hexane and ethyl acetate). The ability of white galangal extract in inhibiting bacteria was tested using the Kirby Bauer method (paper disc). The concentration of galangal extract tested was 0%; 5% ; 10% ; 15%; 20% (w/v), control (ciprofloxacin) and MIC (Minimum Inhibition Concentration). To determine the toxicity of the extract, the LC50 test was carried out. Meanwhile, to determine the class of compounds contained in the galangal extract, phytochemical tests were carried out using the phytochemical screening method. The results showed that white galangal extract with 96% ethanol as solvent and n-hexane was able to inhibit the test bacteria. Inhibition against E. coli O157:H7 was most effective in n-hexane solvent with an extract concentration of 20% (inhibition zone diameter 20.2 mm). while for S.epidermidis was n-hexane solvent with a concentration of 20% (inhibition zone diameter 23.5 mm). LC50 against E. coli O157:H7 with 96% ethanol and n-hexane as solvents 11.2% and 10.4%, respectively. Meanwhile, the LC50 of S. epidermidis with 96% ethanol and n-hexane solvents were 9.9% and 9.3%, respectively. Qualitatively, white galangal plant extract contains a class of flavonoid compounds, saponins, terpenoids, and tannins.

Abstract

Sodium nitrite (NaNO2) is a chemical compound that is often used in food industry. NaNO2 widely used for food preservatives, mainly in processed meat products. However, NaNO2 could cause anemia by interfering with the process of transporting oxygen in the blood. The effects caused by NaNO2 could be repaired with the use of vitamin C. This study was aimed to determine the effect of vitamin C on the blood profile of rats induced by NaNO2, and the effective dose to improve the blood profile of rats. The study used a completely randomized design (CRD) with 4 groups, namely K- (Aquades); K+ (NaNO2 37,5mg/kgBW); C1 (NaNO2 37,5 mg/kgBW + vitamin C 1,8 mg/animal/day); C2 (NaNO2 37,5 mg/kgBW + vitamin C 3,6 mg/animal/day). The samples used in each treatment group were 6 rats, therefore the total sample used was 24 male white rats (Rattus norvegicus) strain Wistar. NaNO2 and vitamin C solutions were administered orally by the gavage method. NaNO2 solution was given until 35th day, then vitamin C solution was given on 22nd to 35th day. Blood samples were taken three times, the day before the administration of NaNO2, on the 21st day, and on the 36th day, further analysis of blood used a haematology analyzer and blood smears preparations Giemsa staining. Data were statistical analyzed by ANOVA and continued with Duncan's test. The results showed that Vitamin C can improve the blood profile, with the most effective dose of vitamin C is 1,8 mg/animal/day.

Abstract

Individual identification is very important in forensics. DNA can be obtained from all parts of the body with the same profile in everyone. Oral mucosal epithelium is one of the sources of DNA that is often used to examine individuals because it is taken using a harmless swab method. Smoke is one of the behaviors that are mostly done by young people or teenagers. Cigarette smoke affects the cells of the oral mucosa because it is a free radical. Free radicals are reactive oxygen compounds which are compounds with unpaired electrons. Deoxyribonucleic acid (DNA) is a nucleic acid polymer that is systematically arranged and is a carrier of genetic information that is passed on to offspring. This study aims to determine the quality and quantity of DNA in non-smoking and smoking students at the State University of Medan, Medan Tembung District, Medan City, North Sumatra Province. Samples were taken by swab method, namely mucosal epithelium from 60 probands consisting of 30 smoker proband and 30 non- smoking proband aged 18-22. The cheek in the probandus is swabbed from the back to the front in one direction. In this study, DNA extraction was carried out using a chelex solution which aims to separate DNA from protein, test the quantity of DNA with a spectrophotometer and test the quality of DNA with agarose gel. The results showed that the average DNA quantity in the oral mucosal samples was 1.96 ng/µL in the smokers proband and 6.92 ng/µL in the non-smoker proband and. The results of the quality test using electrophoresis on agarose gel showed that smoking students had thin bands of fluorescence and in some samples no bands of fluorescence at all. Meanwhile, in the probandus of non-smoker students, there were several samples that showed thin bands of luminescence and stains.

Abstract

Birds have an attraction that has unique colors and melodious sounds, including the Zebra Dove (Geopelia striata). The high economic value of the Zebra Dove (G. striata) for the community causes excessive hunting and trading of these animals so that it can reduce bird populations in the wild. Conservation efforts are carried out to prevent the decline in bird populations in nature, namely bird breeding places. Bacterial contamination is an obstacle during the breeding process of birds. The purpose of this study was to determine the Total Plate Count (TPC) of bacteria and Escherichia coli in samples of contents and shells of Zebra Dove eggs (G. striata) that failed to hatch from several local bird breeders Denpasar, Bali. The research was conducted at the Microbiology Laboratory of the Biology Study Program, FMIPA Udayana University. The method used is the pour plate TPC test on Nutrient Agar (NA) and Eosin Methylene Blue Agar (EMBA) media. The results of the bacterial TPC test in the egg contents and egg shell sample obtained the highest average was found in the third breeder, while the lowest in the first breeder. Escherichia coli TPC results on the egg contents and egg shell sample obtained the highest average was found in the third breeder. The presence of the TPC of bacteria and Escherichia coli in the contents and shell samples of Zebra Dove (G. striata) varied every breeder.

Abstract

Analisis keragaman genetik sangat penting dalam perakitan tanaman jagung (Zea mays L) hibrida. Tujuan dari penelitian ini adalah untuk menganalisis keragaman genetik dari enam varietas jagung menggunakan teknik PCR-RAPD (Polymerase Chain Reaction- Random Amplified Polymorphic DNA). Varietas jagung hibrida yang digunakan dalam penelitian ini adalah varietas jagung Srikandi, Arumba, Mira, Magenta, dan Simba. Varietas jagung lokal yang berasal dari Pulau Rote, Provinsi Nusa Tenggara Timur digunakan sebagai pembanding. Benih ditanam untuk pengamatan karakteristik morfologi dan sampel ekstraksi DNA. DNA diekstraksi dengan metode CTAB dan PCR-RAPD dilakukan menggunakan 3 primer. Ukuran produk PCR ditentukan menggunakan kertas semilog. Keragaman genetik antar varietas dianalisis menggunakan program MVSP (Multi-Variate Statistical Package) dengan metode UPGMA (Unweighted Pair Group Method with Arithmetic Mean). Hasil PCR-RAPD memberikan jumlah pita DNA sebanyak 28 dengan ukuran 310 bp hingga 1550 bp bp dan menghasilkan 23 pita polimorfik. Berdasarkan dendrogram yang dihasilkan dari PCR-RAPD, terdapat satu klaster yang terdiri atas varietas Rote, Srikandi, Arumba, Mira, dan Magenta, serta satu klaster lain yang terdiri atas varietas Simba. Varietas lokal Rote dan varietas hibrida Srikandi memiliki jarak genetik terdekat, sementara varietas Simba memiliki jarak genetik terjauh.
