Abstract

Synbiotic products are a combination of probiotics and prebiotics in food that work synergistically to enhance the survival of beneficial microbes and provide greater health benefits. Durian contains simple sugars, dietary fiber, and oligosaccharides that can be utilized by probiotics as a nutrient source for their growth. This study aims to evaluate the potential of durian (Durio zibethinus) as a prebiotic ingredient in the formulation of synbiotic yoghurt by observing its effects on fermentation characteristics, including microbiological, chemical, and sensory properties, when combined with different concentrations of skim milk and sugar (0%, 5%, and 10%). Total bacteria, lactic acid bacteria (LAB), and titratable acidity increased, while the pH value of the product decreased during the fermentation process. The addition of skim milk and sugar influenced the sensory profile of the product, with the best treatment observed in skim milk and sugar 5% (P8), ba Synbiotic products are a combination of probiotics and prebiotics in food that work synergistically to enhance the survival of beneficial microbes and provide greater health benefits.

Abstract

This study aims to evaluate the accuracy of the branch current analysis method through three approaches: theoretical calculation, simulation using Electronics Workbench (EWB), and experimental measurement using a digital multimeter. The test circuit consists of two 10 V DC voltage sources and three resistors (R1 = 2200 Ω, R2 = 2200 Ω, R3 = 1000 Ω) forming two loops with three branch currents (I1, I2, I3). The theoretical analysis was performed by applying Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL), while the simulation was conducted in EWB software with the same configuration. Direct measurements were obtained by connecting the multimeter in series with each branch. The results show that the simulated current values closely match the theoretical calculations, with a maximum relative error of 0.0084% and an accuracy of 99%. Meanwhile, the experimental measurements exhibit larger deviations compared to the simulation, ranging from 1% to 2 %, with accuracies between 97% and 98%. Overall, the study demonstrates that the branch current method produces consistent results between theoretical calculations and simulations, while the experimental measurements show deviations that remain within acceptable limits due to component tolerances, connection resistance, and instrument accuracy.
