    The aim of the research was to determine the effect of coconut sugar, time length of fermentations and their interaction on the qualities of the red beans (Phaseolus vulgaris L.) fermented milk. The design of the experiment was factorial 3x3 and arranged by the Randomized Complete Design (RCD) with three replications. The first factor was coconut sugar content (3, 6 and 9)%. The second factor was times of the fermentation (16, 18 and 20) hours. The result showed the adding of coconut sugar content and time length of fermentations affected on pH and total titrated acid. The interaction between coconut sugar content and time length of fermentations was not affected to pH, total titrated acid, total lactid acid bacteria and protein content. It was concluded that the best quality of red beans (Phaseolus vulgaris L.) fermented milk was on the 9% of coconut sugar content and 16 hours fermentation (G3T1).

    Penggunaan Lilin Untuk Memperpanjang Umur Simpan Buah Naga Merah (Hylocereus polyrhizus)
    (2013-01-22) Hasibuan, Saddam Husein; Harun,Noviar; Efendi,Raswen
    The aims of this study to determine the effect of combined treatmen wax agains shelf life red dragon fruit (Hylocereus polyrhizus)., this study was done at the Laboratory of Processing and Analysis of Agricultural Products, Faculty of Agriculture, University of Riau. In March to June 2012. The design used in the study was completely randomized design (CRD) with 5 treatments and 4 replications. Treatments were performed during the study were L1: Not given wax emulsion ; L2: Given a concentration of 2% wax emulsion; L3: Given a concentration of 4% wax emulsion; L4: Given a concentration of 6% wax emulsion; L5: Given a concentration of 8% wax emulsion. The resulting data been statistically analyzed with analysis of variance. The are observations made the measurement of total dissolved solids, weight shrinkage measurement, respiration rate measurements and organoleptic tests include skin color, flesh color,are descriptive. The best treatment is the treatment of 6% wax coating with total dissolved solids day to-10: 1,36°brix. Losses weight day to-10: 7,92. Fruit respiration rate day to-10: 14,65 O2/kg.jam
