Abstract

The puspose of this research was to study the symbiotic system of a complex microorganisms contained in Starbact® as a decomposer agent with the addition of photosynthetic microoalgae Chlorella sp. as an oxygen producer in reducing organic loads of sago milling effluent. The experimental design was Completely Randomized Design (CRD) with 5 treatments and 3 replications. The treatments were concentration variations of Starbact® (0, 0.135, 0.270, 0.405, and 0.540 per cent v/v, respectively) with 800 ml/L (6,6 x 106 cell/ml) microalgae Chlorella sp. added up with waste sago milling effluent into total of 2 liters of the liquid. The data obtained were analyzed statistically using Analiysis of Variance (ANOVA) and Duncan’s Multiple Range Test (DNMRT) at 5% level. The result showed that the addition of Starbact microorganisms had significant affect for COD, BOD, TSS, Nitrate, Phospate, DO and pH. The treatment chosen from the result of this research was the P4 treatment showed the highest level of reduction which had the value of COD 88,04%, BOD of 85,27%, TSS of 71,67%, Phospate of 48,21%, Nitrate of 71,06%. The result also showed an increasing of DO as much as 3 times from 1.85 mg/L into 5.91 mg/L, while pH increased significantly from 4.1 into 7.4.

Abstract

The purpose of this research was to study the viability of lactic acid bacteria (Lactobacillus acidophilus) encapsulation in the ice cream with the conditions of low temperature and pH 2. The research was carried out experimentally by using Completely Randomized Design (CRD) with four treatments and four replications, namely: A0, A1, A2, and A3, respectively for alginate 0% (control), alginate 3 %, alginate 4 % and  alginate 5 % (v/v) culture of Lactobacillus acidophilus. Data were statistically analyzed using Analysis of Variance (ANOVA) followed by DNMRT test at the 5% level. Results of this study indicated that the alginate concentration had a significant effect (P<0.05) on the survival of Lactobacillus acidophilus at 0 hour storage, freezing storage for 48 hours, pH 2 and texture of ice cream. The treatment of A3 (Alginate 5 %) resulted in viability Lactobacillus acidophilus on storage 0 hours (99.02%), frozen storage for 48 hours (79.32 %), and the condition of pH 2 (37.33%) was relatively better than others treatments. The best Sensory Evaluation obtained on treatment A0 where the ice cream was no sensation of gel beads and very soft texture. The whole assessment of it was on A0 treatment.
