Abstract

This research aims to find out whether or not there is an effect of the application of the scramble method to the learning outcomes of 5th-grade students on the Events in Life theme at SDN Sumberpinang 02 Jember. This type of research is a quasi-experimental study with a pretest-posttest control group design. The subjects of this study were VA and VB grade students at SDN Sumberpinang 02 Jember with a total of 40 students. Data collection methods through interviews, observations, documents, and tests. The results of the t-test showed that the value of tcount> a table was 2.856 & gt; 0.312, so that the alternative hypothesis (Ha) was accepted and the null hypothesis (H0) was rejected. The calculation of the relative effectiveness test (ER) to determine the effectiveness of the application of scramble learning methods to student cognitive learning outcomes is 46.3% with the medium category.

Abstract

Research on physicochemical properties and antioxidant activity of VCO obtained from Rhizopus orizaefermentation had been done. Antioxidant activity was determined by DPPH method. Production of VCO had been carried out from coconut sample obtained from Pandeglang region with fermentation by Rhizopusorizae in variation of inoculum asfollow 2%, 5%, 7%, 10% and 12 %. Physicochemical test consist of density, refractive index, water content, free fatty acid, iodine value, peroxide value while the composition of fatty acid determined by GCMS, The result showed that variation of inoculum had significantly 0,024 influenced the yielded of VCO producted. Based on this result, quality of VCO still in the range of CODEX Standard, 19-1991rev.2-1999. It was found that antioxidant activity of VCO only 6.3% at 1000 ppm. The composition offatty acid based in lauric acid content measured by GCMS showed a significant result (49.48%-50%) agreed with COD EX Standard.Keyword: Antioxidant, DPPH, veo, Fermentation,Rhizopus oriza.
