Abstract

Target of this research was to obtain solvent type, toobtain ability on antiradical, and to find out optimumconcentration of extract powder of fennel seed. This researchconsisted of two phases that the first phase wasdetermination of total phenol and antioxidant activity usingTBA method at various solvent type. Solvent used forextraction was ethanol and acetate ethyl. The concentrationsof the solvent were 0, 15, 30, 45, 60, 75 and 90%.Antioxidant activity resulted from each variation of type andconcentration of solvent was used for the examination in thesecond phase in determining antiradical activity by DPPH.Variation of concentration of fennel extract was 100, 250,500, 750 and 1000 ?g/ml yielded from type of ethano l andacetate acid solvents.Obtained data of each treatment was plotted in a graph.Data validity was analized using appropriate regressionanalysis on plotted data in graph. Result of research indicatedthat antioxidant active compound extracted using acetateethyl solvent was higher than that using ethanol solvent.Optimum concentration of extract of fennel powder fromethanol and acetate ethyl solvent in scavenging free radicalwas 975 ppm and 850 ppm.

Abstract

The research objective was to study the soluble protein change during process seedgermination. Seed sprout were made in dark room at the room temperature (30 0C) withseveral combination treatment of 3 factor in 5 levels for each factor. The factors are (i)duration of germination process; (ii) duration of soaking process; and (iii) pH of soakingsolution. The analysis of soluble protein was undertaken from extracted sprouts. Data wasanalysed by using the Respon Surface Methodology (RSM) with the central compositedesign (CCD). The research results indicated that the minimum of soluble protein (theincubation of 24 hour in temperature 50 0C with minimum value 4,54% wet weight) wasobtained from the process of 36 hours of germination process, 100 minute of soakingprocess and in pH of 5,65.

Abstract

This research was aimed to optimize the production ofvolatile oil and oleoresin of red ginger crops by optimizingthe usage of compost as fertilizer. Compost was applied as anorganic fertilizer to red ginger crops in poly-bag withfertilization doses 0, 0.2, 0.4, 0.6, 0.8, and 1 kg for one kgcrops planting and red ginger was harvested at 8 and 9months after planting.Red ginger contained volatile oil of 3.8-3.97% DM, totalphenol of 5.7 - 6.4% DM, and ability to catch free radical ofDPPH compound of phenol of 2.5 - 2.6% DM. The quality ofthe red ginger was measured at the age of between 8 and 9months. Depended upon its volatile oil content, ability tocatch free radical DPPH compound of phenol, and its contenton phenol, hence harvest time of ginger could be minimizedto 8 months.
