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.

Abstract

Calotes versicolor, or the oriental garden lizard, is a species of lizard native to South Asia and parts of mainland Southeast Asia. However, in recent decades, its distribution has expanded through human introductions to various archipelagic regions, including Indonesia. On the island of Java, C. versicolor is increasingly found in densely populated areas, agricultural areas, yards, and forest edges. This review article aims to examine the origins of C. versicolor in Java, potential introduction routes, factors for successful invasion, and its impact on local species and ecosystem structure. The method used is a desk study through a review of scientific literature from Google Scholar and online articles. The results of the study indicate that C. versicolor likely spread to Java through inter-island trade routes, agricultural transportation, and human movement routes from the colonial period to the modern era. This lizard's high habitat tolerance, effective reproduction, and opportunistic behavior make it a potential competitor to local lizards such as Bronchocela jubata, Eutropis multifasciata, and several native insect species. Ecological impacts include competition for space and food, predation on invertebrates and small vertebrates, and the potential spread of pathogens. This study emphasizes the importance of population monitoring and regional biosecurity policies to prevent the expansion of the impact of this invasive species in Java.

Abstract

The Pig-nosed turtle (Carettochelys insculpta) is a unique freshwater turtle species naturally distributed in southern Papua and Papua New Guinea. The presence of this species outside its natural habitat is a significant concern in conservation and invasive biology studies. This article aims to examine the presence of Carettochelys insculpta in the Jatiluhur Reservoir, Purwakarta, West Java, and the possible ecological impacts it may have on native species in the reservoir. Discovery data was obtained from an accidental catch by fishermen on December 14, 2025, using fishing nets in the Jatiluhur Reservoir. The research method used a desk study with data sources derived from scientific articles indexed by Google Scholar, online articles, and social media documentation on Facebook and TikTok related to the discovery of the species. Due to the lack of direct morphometric data, an estimation approach was carried out using Artificial Intelligence (AI) Gemini by analyzing the proportion of human hand size to the pig-nosed turtle's body in documentation photos. The analysis results showed that the individuals found had a Carapace Curve Length (CL) of approximately 45–55 cm, a Carapace Curve Width (CW) of approximately 35–45 cm, and a carapace diameter of approximately 40 cm, with an estimated total body length of 60–70 cm. These measurements indicate that the individuals were mature but had not yet reached the maximum size of the species. The presence of this species in the Jatiluhur Reservoir is suspected to be related to releases from the exotic or pet trade. The presence of C. insculpta has the potential to affect ecosystem balance through competition for space and food resources with local species, although further research is needed to determine the population status and its ecological impacts.

Abstract

Kombucha is a fermented tea beverage produced using a Symbiotic Culture of Bacteria and Yeast (SCOBY) and is recognized as a functional drink due to bioactive compounds with antioxidant properties. The incorporation of traditional Indonesian herbal ingredients, such as beras kencur, offers the potential to enhance its functional value. This study aimed to evaluate the effect of different fermentation periods on the chemical characteristics of beras kencur kombucha and determine the optimum fermentation period. A Completely Randomized Design (CRD) was used with four fermentation periods (0, 7, 14, and 21 days), each replicated six times. The observed parameters included pH, total titratable acidity, vitamin C content, total phenolic content, total flavonoid content, and antioxidant activity. Data were analyzed using one-way analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Fermentation period significantly affected pH, total titratable acidity, vitamin C content, total phenolic content, and total flavonoid content (p < 0.05), but had no significant effect on antioxidant activity (p > 0.05). Longer fermentation decreased pH and vitamin C content, while increasing total titratable acidity, total phenolic and flavonoid contents, and antioxidant activity. The 21-day fermentation period produced the most desirable chemical characteristics, including a pH of 3.22, a total titratable acidity of 2.78%, an antioxidant activity of 44.29%, the highest total phenolic and flavonoid contents, and the lowest vitamin C content (6.97 mL/L). Therefore, a 21-day fermentation period was identified as the optimum treatment for producing beras kencur kombucha with enhanced functional properties.
