The objective of this study was to isolate actinomycetes from soil of tea plantations, Jamus ngawi as a microbiology lab manual chapter isolation and characterization of microbes. The medium used is the medium of MHA and MHB. Soil samples taken to a depth of 10-15 cm from the surface with capture location is about 07o 41'53,07 'S and 111o 37' 24.64 '' E. The isolates were obtained observed morphologic characters include colony shape, colony color, surface characteristics of colonies, colony growth, colony elevation, and the edge of the colony. Isolates of actinomycetes were successfully isolated are Streptomyces, Nocardia and Nocardiopsis. Actinomycetes isolates have been found that can be used as a collection of the microbiology laboratory.

Rhodamin is one of additional food ingredient which often used to recolour the food.The additional food ingredient contains carsinogenic which can affect our health with a cancer asthat ingredient is not acceptable ingredient for food. Unfortunately,many Indonesian do not knowwhether the syntetical ingredients can be used or that is being prohibited to use. The purpose ofthis research is not only to observe whether there is Rhodamin B inside the tomato sauces aroundMadiun, but also to get the result of the analysis as the mateial for aditif subtance experiment inBio-chemical lesson. Furthermore, this descriptive qualitative research used non randomsampling as its technique. The sample is taken from pentol seller, mie ayam seller and baksoseller. The samples are being analyzed with Kremtografi Lapis Tipis (KLT). The result of theanalysis showed that all of the sample is negative. On the other hand, there is no Rhodamin B onit. The indicated sample has the same Rf with Rhodamin B. It will change it color into red as itsresponse toward H2SO4 and HCl. The sample also being compared with wantex. The resultshowed that the Rf samples had A3, A4, A5, B4, B5,C1, C2, C3, C4 dan C5. Based on the result,the assumption of the samples is that the samples have wantex material on it

Biofilm merupakan komunitas bakteri yang terorganisasi, terakumulasi dalam metriks polimer (EPS) atau disebut juga slime yang diproduksi oleh bakteri itu sendiri dan mampu melekat pada permukaan hidup maupun tak hidup. Infeksi yang disertai dengan pembentukan biofilm sulit ditangani secara efektif oleh sistem kekebalan tubuh inang dan tahan terhadap pengobatan dengan antimikroba. S. aureus bersama dengan S. epidermidis merupakan agen penyebab infeksi antara lain infeksi implan medis dan infeksi nosokomial di seluruh dunia. Patogenesis infeksi S. epidermidis terkait dengan pembentukan biofilm. Patogenesis S. aureus disebabkan oleh efek gabungan dari faktor ekstraselular dan toksin, bersama dengan sifat invasif strain seperti perlekatan, pembentukan biofilm, dan ketahanan terhadap fagositosis. Metode Congo Red Agar (CRA) sebagai metode fenotipik yang cukup murah dan mudah dengan kriteria evaluasi didasarkan pada analisis visual warna koloni yang tumbuh pada media agar. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisa kemampuan pembentukan slime pada isolat Staphylococcus epidermidis, Staphylococcus aureus, MRSA dan E. coli. Uji pembentukan slime bakteri dengan Metode CRA dilakukan dengan menanam isolat bakteri S. epidermidis, S. aureus (MSSA 1 dan MSSA 2), MRSA 1 dan E. coli (S4 dan S55) yang telah diremajakan ke media CRA dalam cawan petri dengan metode streak 4 area. Menginkubasi selama 24 jam pada suhu 37° C pada kondisi aerobik. Interpretasi hasil menurut ketentuan sebagai berikut: strain menghasilkan koloni warna hitam pekat, hitam, dan hitam kemerahan dianggap memproduksi slime, sedangkan koloni merah dan kemerahan diklasifikasikan sebagai tidak memproduksi slime. Kesimpulan penelitian ini adalah isolat bakteri S. epidermidis, S. aureus dan MRSA dengan metode CRA (Congo Red Agar) diketahui mampu membentuk slime sedangkan isolat bakteri E. coli menunjukkan hasil yang bervariasi.
