The research objective was to get the starter type and the fermentation time to produce soygurt that have a high peptide bioactive that functions as an antimicrobial. The study was conducted in a complete randomized block design with two replicates. The first factor is the starter types, which consists of 3 levels, 2 market starter (cimory and king yogurt) and 1 mixed starter. The second factor is the fermentation times, which consists of 3 levels, 9 hours, 12 hours, and 15 hours. The data obtained were analyzed by analysis of variance to get various error estimators and tests of significance by Duncan's test further to determine whether there is a difference between treatments. Two market starter (cimory and king yogurt) and 1 mixed starter did not produce peptide bioactive compounds . It is suspected microbes contained in the market starter cimory (S.thermophilus and L.delbrueckii ssp . Bulgaricus ), the market starter king yogurt (L.bulgaricus) and mixed starter (S.thermophilus and L.bulgaricus) did not produce peptide bioactive compounds. The inhibition effect of the test bacteria (E. coli and S. aureus) occurs due to the production of lactic acid and hydrogen peroxide during the fermentation process . The greatest inhibition shown by soygurt of the market starter cimory with a reduced number of cells in both types of test bacteria (E. coli and S. aureus) at 6 and 5 log cycles . Mixed starter has the lowest pH and the highest total acid than the marker starter cimory and king yoghurt. The starter types and the fermentation times were no significant effect on total dissolved solids of soygurt. The levels protein of soygurt, respectively 1.38 %, 1.48 %, and 1.68 (cimory, king yogurt, and mixed starter), while the fat content of soygurt 1.04%, 1.28 %, and 1.58% (cimory, mixed starter, king yoghurt) Keyword: soygurt, peptide bioactive, antimicrobe

Until the current level of dependence on agricultural products in DKI-Jakarta from other areas increasing, estimated level of vegetable consumption / capita in urban -9.8 1.1% higher if compared to rural areas. Increased production and plant health conducted with crop rotation, intercropping, planting the right varieties, biological pest control. One of the environmentally-friendly technologies that can be used to improve the quantity and quality of the horticultural farming is very suitable for the conditions in Jakarta are the organic farming. The purpose of the study, assessing alternative technology packages organic farming leaf vegetable crops in the dry season, conducted from May to December 2008. This assessment activities carried out in Rawasari, Jakarta-Central, involving 6 farmer cooperators. As the indicator is a mustard plant. The design used was a randomized block design with 6 replications and 4 were tested technology package include: a) BPTP fertilizer (from urban waste)+Pest control with Nemasal (botanical pesticides), b) Fertilizer Dharmajaya (from beef cattle waste)+Pest control with sweeping (sweep with cloth), c) Fertilizer Pegadungan (from enceng gondok+stater)+Pest control with sweeping and d) Farmers fertilizer (chicken manure+Urea)+control OPT with Curacron/decis. The results of study of organic technology package on leaf vegetable crops (mustard) in DKI-Jakarta showed that, using fertilizer Dharmajaya (waste from the abattoir) with sweeping OPT can increase the growth and yield of mustard plants, equivalent if using fertilizer formulations BPTP (waste from urban waste + enrichmen). With the use of packet 1, it gives the highest profit, ie the B / C ratio: 3.8. While the B / C ratio is the lowest obtained in the use of packet 3, the gain B / C ratio is less than 1. It shows that, organic farming technologies provide considerable opportunities high in leaf vegetable farming, especially in the mustard plant in the dry season.
