Abstract

Antiobesity with a lipase inhibitor mechanism will block the hydrolysis of triglycerides into fatty acids and glycerol, while antioxidant compounds are very useful in conditions of obesity to prevent excess damage from degenerative diseases. Curcuma aeruginosa Roxb extract has been proven to have the effect of inhibiting pancreatic lipase so further effects will be seen at the fraction level. The purpose of this research is to investigate the phytochemical components ,antioxidant activity and pancreatic lipase inhibition of Curcuma aeruginosa Roxb fractions. Ethanolic extract of the Curcuma aeruginosa Roxb rhizome was separated using the solid-liquid chromatography with 3 different solvents (n-hexane, ethyl acetate, ethanol) to give n-hexane (HF), ethyl acetate (EAF), and ethanol (EF), and the insoluble (IF) fractions. Each fraction detected phenolics, flavonoids, alkaloids, tannins, saponins, triterpenoids/steroids. EF has the highest total flavonoid and phenolic content. Antioxidant activity of all fractions were measured using DPPH reduction, ABTS, and FRAP methods. The best antioxidant activity of all fractions using the DPPH method was EF with IC50 21.93 ± 3.39µg/mL, ABTS method was HF with IC50 24.56±1,03 µg/mL and FRAP method was IF with IC50 20.79±1,03 µg/mL. Totals of phenolics and flavonoids in EF strongly support the antioxidant activity of the DPPH method. The highest inhibition of pancreatic lipase was found in EAF at 35.16±0.24 % (100 µg/ml). There was significant difference between EAF and xenical (orlistat) (p

Abstract

In recent years, the exploration of natural supplements such as green tea extract and their potential benefits in livestock nutrition has gained considerable attention among researchers and agriculturalists. Green tea extract contains a high concentration of bioactive substances, such as polyphenols and catechins. This study aimed to explore the effects of varying doses of green tea extract on rumen fermentation parameters through an in vitro trial using sheep rumen liquids. A completely randomized experimental design was utilized to test the effect of 4 different doses of green tea extract treatments (0, 140, 280, and 560 mg/kg) on in vitro Hohenheim gas test method. The current study shows no significant effect of administering green tea extract at various doses on total gas production, total gas production per in vitro dry matter and organic matter degradability, volatile fatty acid per in vitro dry matter and organic matter degradability, methane production per inv vitro dry matter and organic matter degradability of green tea extract. Although no significant effects were observed on the investigated parameters, this study provides important insights in the understanding of the potential use of green tea extract in modulating fermentation processes in the ruminant’s stomach. In conclusion, the findings of this study underscore the impact of GTE on gas production regulation, highlighting its potential implications for gastrointestinal health

Abstract

Ganoderma spp. is a genus of macrofungi in the Basidiomycota, comprising both saprophytic and phytopathogenic species. Ganoderma spp. prefers woody substrates and can attack various trees in the forest. While it often acts as a phytopathogenic fungus, it also serves an ecological role for surrounding insects, providing food and shelter. This study aims to determine the interactions and preferences of Ganoderma spp. with its hosts and to observe the interactions between Ganoderma spp. and surrounding insects. Research on these interactions was conducted through scan sampling exploration in the Gunung Walat Educational Forest. Identification of fungi, trees, and insects was based on morphological characteristics. A total of 155 fruiting bodies of Ganoderma were found. Three species of Ganoderma were successfully collected and described morphologically, both macroscopically and microscopically. Ganoderma spp. were found infecting Agathis sp., Schima wallichii, and Pinus merkusii trees. The fruiting bodies of Ganoderma spp. interacted with insects such as larvae, Trichomyrmex destructor ants, and Eumorphus marginatus beetles, which used the fruiting bodies as breeding and shelter sites

Abstract

Penata Besar Island is designated as one of the Coastal and Small Island Conservation Areas (KKP3K) in West Kalimantan, is a critical site for conserving coral reefs and reef fish. Currently, global climate change and anthropogenic activities have exacerbated coral reef bleaching worldwide. In the context of escalating global climate change and human-induced threats, this study evaluates the health condition of coral reefs in the northern waters of Penata Besar Island, Bengkayang Regency. An exploratory approach was employed, utilizing the Line Intercept Transect (LIT) method across four stations at two distinct depths (2-3 m and 5-6 m). The results revealed that coral cover varied with depth. At a depth of 2-3 m, live coral coverage was between 51.2% and 62.4%, classified as good, while at 5-6 m, coverage ranged from 30.4% to 49.4%, categorized as fair. Coral Massive (CM) was the predominant growth form observed. The diversity index (H') ranged from low to medium, the Evennes index (E) from medium to high, and the dominance index (C) was categorized as low. These findings highlight the varying health of coral reefs in different depths and provide a basis and essential insights for targeted conservation efforts.

Abstract

Red onion (Allium cepa) is a plant that requires sufficient water and is susceptible to drought stress. The use of biofertilizer is employed because it contains microorganisms that enhance nutrient availability and assist plant growth under abiotic stress conditions. This study aims to analyze the physiological and anatomical responses of red onion bulbs following the application of biofertilizer under drought stress. The doses of biofertilizer used were 0; 10;15; and 20 L/ha with field capacity levels of 25; 50; 75 and 100%. The parameters tested were bulb diameter, reducing sugar content number of bulb layers, anatomy of root cortex thickness, anatomy of root metaxylem diam Red onion eter, and fresh weight of red onion roots. The method used in determining the level of reducing sugar is the Nelson-Somogyi method. The method used for preparing the red onion root specimens was the embedding method. The results showed that the largest red onion bulb diameter was obtained from treatment A1B2, without the addition of biofertilizer at 75% field capacity. Meanwhile, the highest reduced sugar content was found at a dose of 15 L/ha with 50% field capacity
