Abstract

Andaliman contains active compounds including flavonoids, glycosides, tannins, and has a unique taste, which is a spicy blend with the lemon flavor can be used as a natural preservative to reduce the number of bacteria, prolong the time of rot and the acceptability of meat. The aim of the study was to determine the effect of using the different concentrations of andaliman fruit extract and to determine the best concentration that could reduce the total number of bacteria, delay the onset of spoilage and maintain acceptability. The experimental study used a completely randomized design, with four concentrations of andaliman fruit extract; 0% (P1), 0.25% (P2), 0.50% (P3), and 0.75% (P4). Analysis of variance was used to determine the effect of the andaliman extract concentration on total plate count and the onset of spoilage. The differences between the treatments were observed using Duncan’s multiple range test. The acceptability was analyzed using Kruskal-Wallis’s test and Mann-Whitney’s test. The results showed that the marination using andaliman extract at 0.75% gave the best results in terms of total plate count of 7,9 x 106 cfu/g, the onset of spoilage at 717 minutes and acceptability by the panelists.

Abstract

Phytoremediation is an effort to restore polluted land by absorbing, degrading, removing, stabilizing, or transforming pollutants using hyperaccumulator plants. Mexican Sword plants in phytoremediation are used as hyperaccumulators that can reduce heavy metal content by rhizofiltration mechanism. This study aims to determine the effect of mexican sword plant quantity on chromium concentration, pH value, and Dissolved Oxygen (DO). The research was conducted using an experimental method using a Completely Randomized Design (CRD), with 4 treatments, P0 = 0 mexican sword plants, P1 = 4 mexican sword plants, P3 = 6 mexican sword plants, P4 = 8 mexican sword plants. Repetition was carried out five times for each treatment. The data obtained were analyzed statistically by Analysis of Variance at = 5% and if there is a significant difference, further tests will be carried out using the Tukey test. The results showed that there was a significant difference (P<0.05) for each quantity of mexican sword plants concerning chromium concentration, pH value, and Dissolved Oxygen (DO). The best treatment results were shown by the quantity of 6 individuals (P2) with a Chromium concentration of 16.87 mg/L, a pH value of 8.45, and a DO of 1.3%.
