BIO-MASTIC (Mastitis Natural Antiseptic), Pemanfaatan Ekstrak Daun Kersen sebagai Antiseptik Tear Dipping
"BIO-MASTIC" is based natural antiseptic compounds containing antibacterial protection cherry leaves. thing more support in making this antiseptic is a special antiseptic product innovation Teat Dipping that has never existed in the market, another advantage with natural ingredients that have been tested, so as to provide protection of live stock against the disease through treatment mastitis post-milking TeatDipping. This productis more economical prices so that farmers do not spend a lotto take care of their animals. "BIO-MASTIC" has great potential to be developed areas such as dairy cattle centers in poor districts and Kota batu and can earn big profit. The Progress of programs divided into six stages including market research and planning, the purchase of means of production, the search for raw materials, implementing production, testing and marketing of products. Stage of market research conducted in the central areas of the dairy farm, the method used is to interview farmers to dairy farmers. Production Stage conducted in the Laboratory of FKM(Microtechnic Physiology and Plant Tissue Culture, the amount of production for 4 months obtained 248 liters. Stage product testing carried out in the laboratory of FKM (Physiology, Plant Tissue culture and Microtechnic) Faculty of Biology and Bacteriology laboratory Brawijaya University. at the marketing stage, we aim at a target market that is central areas of the dairy farm. Mean while applied marketing strategy is to go to the breeder directly and in cooperation with Prosperous UD.Sumber. Moreover, we follow the bazaars both campus and national levels.

The Effect of various Sterilization Procedure on Number of Colony-Forming units of isolated endophytic bacteria from Cosmos caudatus Kunth. leaf
The purpose of this study was to determine the effect of different concentration and time sterilization on the number of colony-forming units of isolated endophytic bacteria from Cosmos caudatus kunth. leaf. The sterilizing agents were used is sodium hypochlorite (NaOCl). The research consisted of four treatments P1 (NaOCl 5.35%; 3 minutes), P2 (NaOCl 5.35%; 1,5 minutes), P3 (NaOCl 3%; 3 minutes), and P4 (NaOCl 3%; 1,5 minutes). Every treatments have one control medium and three repetition. The control medium treated by make streak using C. caudatus leaf that had sterilized and the three repetition treated by inoculating 100 µL suspension of C. caudatus leaf with 10-1 serial dilution. Result on the control medium is sterile and indicated that the bacteria in treatments medium is endophytic bacteria. The CFU in treatments P1 (0x102 CFU/ml), P2 (2,9 X 103 CFU/ml), P3 (2,9 X 103 CFU/ml), and P4 (2,8 X 103 CFU/ml). The conclusion from this study is there was no significantly different of different concentration and time sterilization on the number of colony-forming units of isolated endophytic bacteria from Cosmos caudatus kunth.
