Propolis adalah resin alami yang dikumpulkan oleh lebah madu dari tumbuhan dan digunakan secara luas dalam pengobatan tradisional. Sifat antibakteri dan antijamur dari ekstrak propolis telah diselidiki secara ekstensif, namun belum diketahui konsentrasi efektif propolis untuk diformulasikan sebagai salep antibakteri terhadap Staphylococcus aureus. Penelitian ini bertujuan untuk menentukan konsentrasi efektif ekstrak propolis dalam sediaan salep untuk menghambat pertumbuhan Staphylococcus aureus. Pengujian aktivitas antimikroba dilakukan dengan metode difusi menggunakan kertas cakram dengan masa inkubasi 24 jam. Diameter hambatan yang terbentuk diukur dan dianalisis secara statistik menggunakan metode Rancangan Acak Lengkap (RAL). Hasil penelitian menunjukkan diameter hambatan rata-rata salep propolis 1% sebesar 9,5 mm, 5% sebesar 9,7 mm, 10% sebesar 10,8 mm, dan kontrol positif sebesar 15,5 mm. Hasil analisis statistik nilai F hitung (36,6) > F tabel pada taraf 1% (7,591) dan 5% (4,006), sehingga menunjukkan ada pengaruh variasi konsentrasi ekstrak propolis pada sediaan salep terhadap luas diameter hambatan pada taraf 1% dan 5%. Disimpulkan bahwa konsentrasi yang efektif ekstrak propolis dalam sediaan salep dalam menghambat pertumbuhan Staphylococcus aureus adalah 1%.

A Research isolation and identification of bacteria termofil amylase from hot springs Lejja South Sulawesi has been done. This study aims to characterize the morphological, biochemical, genus and species of bacteria producing the enzyme amylase. The method used in this study through the stages: 1) Skrening and isolation of bacteria by means of as much as 1.0 mL of sample dilution plated on Petri dishes containing agar medium, then incubated for 20-24 hours at 50 °C, colonies of bacteria growing and has a colony morphology different character each taken 1 ose then etched into the amylolytic selective medium then incubated for 20-24 hours at 40oC and 50oC. Colonies that grew on selective media is scratched quadrant amylolytic to obtain pure isolates. Pure bacterial isolates taken 1 ose then grown in selective medium for 48 h at 50° C, bacterial isolates were grown spilled iodine solution (2% I2 and 0.2% KI) when there is a clearing zone around the colony indicated as the enzyme-producing bacterial isolates termofil amylase; 2) termofil characterization of bacterial isolates in microscopy with Gram stain; 3) isolates selected biochemical tests performed according to the method Bergey's Manual and Systematic of Bacteriology. Results of screening and isolation of 10 bacterial isolates obtained amylase through iodine test, selected 2 isolates, 1 isolate from water samples RSAII-1B and 1 isolates from water samples mixed sediment RSSII-4B, which has a diameter of clearing zone of 5.6 cm respectively and 5.15 cm; out such characterization results of gram stain microscopy showed that the 2 isolates including gram + and shaped bacillus, the colony morphology as observed macroscopically, microscopy and biochemical test results obtained RSAII isolates and isolates RSSII-1B-4B is a Bacillus sp.

This study aimed to 1) determine the degree of saturation of ammonium sulfate right to extract and purify the bioactive protein from shells (Atactodea striata), 2) determine the fraction of active protein from shells (Atactodea striata) as a potential antibacterial. In this study used the Lowry method for determine protein concentration and agar diffusion method for antibacterial activity. Extraction of shells Atactodea striata was conducted by making use of buffer solution (0,1 M Tris-HCl of pH 8.3, 2 M NaCl, 0.01 M CaCl2, 1 % β-mercaptoethanol, and 0.5 % Triton X-100). Purification of proteins by precipitation using ammonium sulfate at saturation level 30 %, 50 %, 70 %, and 90 %. The results showed that the protein concentration of the crude extract is 41.6354 mg/mL. At fractionation rate of 0-90% saturation showed the highest concentration of protein found in fractions with 70% saturation level is 56.4184 mg/mL. The testing of antibacterial activity against Staphylococcus aureus showed that crude extracts and protein fractions Atactodea striata is considered effective as an antibacterial. The highest bioactivity during 24-hour incubation in protein fractions obtained by ammonium sulfate saturation level of 50% is 25.17 mm. Whereas the lowest activity was obtained at 90% saturation level is 14.05 mm. Bioactivity against Escherichia coli after incubation for 24 hours has the highest activity in the protein fraction with 30% ammonium sulfate saturation is 15.12 mm. Whereas the lowest activity was showed at 70% saturation level is 10.30 mm. After the observation was continued for 48 hours on both test bacteria, which formed a clear area becomes cloudy. It shows that the crude extract and fractions of protein tend to be bacteriostatic against Staphylococcus aureus and Escherichia coli.
