PENGARUH KONSENTRASI BERTINGKAT ANTIBAKTERI PROPOLIS LEBAH MADU DALAM MENGHAMBAT PERTUMBUHAN BAKTERI Methicillin Resistant Staphylococcus aureus (MRSA)

Latar Belakang : Saat ini, telah dilaporkan penurunan kepekaan MRSA terhadap antibiotik vankomisin sebagai terapi utama. Oleh karena itu, diperlukan studi untuk mengidentifikasi alternatif pengobatan lain dari bahan alam yang memiliki sifat antimikroba, salah satunya adalah propolis.

Tujuan : Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi bertingkat antibakteri propolis lebah madu dalam menghambat pertumbuhan bakteri MRSA.
Metode : Penelitian in vitro ini menggunakan rancangan acak lengkap dengan desain post test only with control group. Dilakukan randomisasi terhadap seluruh sampel yang diteliti. Pengukuran aktivitas antimikroba dilakukan dengan metode difusi cakram. Konsentrasi propolis yang diteliti yaitu 12,5%; 25%; 50% dan 100% dengan kontrol positif cefoxitin 30µg dan kontrol negatif akuades sebagai pembanding. Pengujian masing-masing kelompok perlakuan dilakukan sebanyak lima kali pengulangan. Analisis bivariat menggunakan uji nonparametrik Kruskall-Wallis dan diikuti uji post-hoc Mann-Whitney. Hubungan dikatakan bermakna apabila nilai p<0,05.
Hasil : Peningkatan konsentrasi propolis akan menghasilkan aktivitas antibakteri yang semakin tinggi (p<0,05). Diameter zona hambat yang dihasilkan berturut-turut dari konsentrasi terkecil sebesar 12 mm; 14,4 mm; 15,6 mm; dan 17,6 mm.
Kesimpulan : Konsentrasi bertingkat antibakteri propolis lebah madu memiliki pengaruh dalam menghambat pertumbuhan bakteri MRSA.

Background: A decrease in the sensitivity of MRSA to vancomycin has been reported as the mainstay of therapy. Therefore, studies are needed to identify other alternative treatments from natural ingredients that have antimicrobial properties, one of which is propolis.
Objective : This study aims to determine the effect of antibacterial graded concentration of honey bee propolis in inhibiting the growth of MRSA bacteria.
Method : This in vitro study used a completely randomized design with a post test only design with a control group. Randomization was carried out on all samples studied. The measurement of antimicrobial activity was carried out by the disc diffusion method. The concentration of propolis studied was 12.5%; 25%; 50% and 100% with positive control cefoxitin 30µg and aquadest negative control as comparison. The test for each treatment group was repeated five times. The bivariate analysis used the Kruskall-Wallis nonparametric test and was followed by the Mann-Whitney post-hoc test. The relationship is said to be signficant if p<0.05.
Result : Increased concentration of propolis will result in higher antibacterial activity (p<0,05). The inhibition zone diameter from the smallest concentration was 12 mm; 14.4 mm; 15.6 mm; and 17.6 mm, consecutively.
Conclusion : The gradual concentration of honey bee propolis has an effect in inhibiting the growth of MRSA.

2923432567H1B016019KONTRIBUSI PENGGUNAAN CALCIUM STEARATE SECARA BERVARIASI TERHADAP GAYA LENTUR BALOK BETON MUTU 30 MPA DENGAN BAHAN PENGIKAT PORTLAND POZZOLAN CEMENT DAN FLY ASHBeton merupakan material yang memiliki banyak pori kapiler, sehingga rentan sekali terjadi korosi. Calcium stearate atau Ca(C18H35O2)2 merupakan bahan tambah yang tidak mengandung unsur perusak beton dan baik dalam menurunkan laju korosi serta berpotensi meningkatkan kuat lentur karena senyawa ini aktif mengisi celah retak mikro dan pori-pori pada beton. Penelitian ini bertujuan untuk mengetahui pengaruh kuat lentur dan pola keretakan balok beton bertulang dengan bahan tambah calcium stearate variasi 0 , 1 , 5 , 10 kg/m3 dari volume beton pada mutu 30 MPa. Menggunakan balok beton berdimensi (150x100x1000) mm dengan baja tulangan 2D16 tulangan utama dan P8 tulangan sengkang. Hasil penelitian menunjukan tegangan lentur rerata dengan komposisi calcium stearate 0 kg/m3 yaitu 26,069 MPa, 1 kg/m3 yaitu 28,071 MPa, 5 kg/m3 yaitu 25,852 MPa, dan 10 kg/m3 yaitu 19,037 MPa. Hasil tersebut menerangkan bahwa semakin tinggi kadar calcium stearate akan menurunkan kuat lentur beton walaupun demikian kadar calcium stearate 1 kg/m3 merupakan yang optimal dan pola keretakan yang terjadi adalah keretakan geser (web shear crack).Concrete is a material with many capillary pores, therefore it is very susceptible to corrosion. Calcium stearate or Ca(C18H35O2)2 is an additional material without concrete destroying elements and good at reducing corrosion rates as well as has the potential to increase flexural strength because this compound actively fills micro-crack gaps and pores in concrete. This research aims to determine the effect of flexural strength and cracking patterns of reinforced concrete beams with additional calcium stearate variations of 0, 1, 5, 10 kg/m3 from concrete volume at 30 MPa quality. This research uses concrete beams with dimensions (150x100x1000) mm using 2D16 main reinforcing steel and P8 reinforcing bars. The results showed that the average bending stress with a calcium stearate composition of 0 kg/m3 was 26,069 MPa, 1 kg/m3 was 28,071 MPa, kg/m3 was 25,852 MPa, and 10 kg/m3 was 19,037 MPa. These results indicate that the higher the calcium stearate content will reduce the concrete flexural strength, however the 1 kg/m3 composition of calcium stearat was the optimum and the crack pattern is the web shear crack.
