Abstract

Vinegar is a fermentation product produced through two main stages, namely anaerobic alcohol fermentation by Saccharomyces cerevisiae and aerobic acetic acid fermentation by Acetobacter aceti. Dates (Phoenix dactylifera L.) have a high simple sugar content so they have the potential to be used as raw material for vinegar production. This study aims to evaluate the organoleptic characteristics of date vinegar based on color and aroma parameters in various combinations of Saccharomyces cerevisiae and Acetobacter aceti concentrations. The study used a factorial Completely Randomized Design (CRD) with two factors, namely the concentration of Saccharomyces cerevisiae (0.1%; 0.2%; 0.3%) and the concentration of Acetobacter aceti (5%; 10%; 15%), resulting in nine treatment combinations. Organoleptic tests were conducted using a hedonic test involving 30 untrained panelists. Data were analyzed descriptively and statistically tested using the Friedman test, followed by the Wilcoxon test if there was a significant difference (p < 0.05). The organoleptic test results showed that the panelists' preference for the color and aroma of date vinegar differed between treatments. Treatment Y3V3 (0.3% Saccharomyces cerevisiae and 15% Acetobacter aceti) obtained the highest color preference value (4.07 ± 0.81), while treatment Y1V1 (0.1% Saccharomyces cerevisiae and 5% Acetobacter aceti) obtained the highest aroma preference value (3.73 ± 0.89). The Friedman test showed significant differences in color (p = 0.000) and aroma (p = 0.018) parameters. The Wilcoxon test confirmed differences in preference levels across several treatment pairs. Thus, variations in the concentration of Saccharomyces cerevisiae and Acetobacter aceti affected the organoleptic characteristics of date vinegar, especially color and aroma, which have implications for consumer acceptance.

Abstract

Silver barb (Barbonymus gonionotus) is one of the most widely consumed freshwater fish species in Indonesia. Ectoparasitic infections can interfere with fish culture practices, particularly under intermittent fasting regimes; therefore, continuous monitoring is required to anticipate potential infestations. This study aimed to identify ectoparasite species, evaluate the effect of fasting on ectoparasite intensity, and determine the prevalence of ectoparasites in silver barb cultured in a polyculture system. This study employed an experimental method using a Completely Randomized Design (CRD) consisting of three fasting treatments with ten replicates each. Fish sampling was conducted using random sampling techniques. The treatments included fasting on Monday (P1), fasting on Monday and Thursday (P2), and fasting on Monday, Wednesday, and Friday (P3). The ectoparasites identified were Monogenea, Trichodina sp., and Ichthyophthirius multifiliis. The results indicated that different fasting treatments did not significantly affect ectoparasite intensity. The prevalence of ectoparasites ranged from 10% to 100% across treatments. Throughout the cultivation period, water quality parameters remained within the acceptable standards for Class III water quality.
