Abstract

This study aims to determine the effect of adding watermelon rind waste on the physical quality of durian ice cream. The design used was a one-factor Randomized Block Design (RBD) with four treatments and three repetitions. The treatments involved different ratios of watermelon rind pulp: 0%, 10%, 20%, and 30%. The observation data were analyzed using a 5% level Analysis of Variance (ANOVA) with Co-Stat software. If there were significant differences, further tests were conducted using the Honest Significant Difference (HSD) test. The research results indicate that watermelon rind pulp in durian ice cream yielded significantly different results regarding overrun percentage, resistance, and sensory parameters including aroma, taste, and texture. The best results for ice cream with added watermelon rind were obtained from the 30% treatment, with a physical characteristic of 73.42% overrun and 20.14 minutes resistance. Durian ice cream with 30% added watermelon rind has sensory characteristics of a slightly watermelon albedo aroma, a somewhat soft texture, and a slightly astringent taste. Therefore, it can be concluded that the addition of watermelon rind waste affects the physical and sensory characteristics of ice cream.

Abstract

Lactobacillus plantarum (L. plantarum) is a type of Lactic Acid Bacteria (LAB) that can convert glucose into lactic acid. L. plantarum can mostly be found in milk, meat, fermented vegetables, and the human digestive tract. The L. plantarum bacteria has several strains, each of which has a good function in food fermentation and health. To understand the historical development of an organism's evolution, it is necessary to use phylogeny as the basis for systematic science in biological evolution. The aim of this research was to determine the genetic structure and level of relationship between L. plantarum bacteria isolated from food products. The data used in this research is secondary data taken from GenBank in the form of nucleotide sequences from the bacterium L. plantarum which were then analyzed using clustal W in the Bioedit application, then genetic and phylogenetic structure analysis was carried out using the MEGA 7 application. The results showed that the probability of substitution was the highest. detected in base G, followed by bases A, T/U, and C. The L. plantarum strain that has the highest level of relationship is the strain with GenBank codes AY424355.1 and AJ640082.1 with a bootsrep value of 99. The resulting phylogenetic tree topology is monophyletic, which means that all members in the group come from a common ancestor who passed on genetic, morphological and biochemical characteristics to his descendants.
