Abstract

This study investigated the antioxidant activity of swallow nests known as Edible Bird Nests (EBNs) derived from the swallow species Collocalia linchi, especially those sourced from Lombok, Indonesia with various health benefits, including their potential as antioxidants. This study used swallow nest samples taken from 3 different locations, namely: East Lombok, Central Lombok and West Lombok. The extraction method used is heating and sonication. Antioxidant activity was assessed quantitatively using the DPPH method and measured by UV-Vis spectrophotometry. Results showed varying IC50 values across different extraction times, with the highest values recorded at 3818.47 mg/mL and the lowest at 2331.47 mg/mL, compared to the control (ascorbic acid) at 35.22 mg/mL. The higher the IC50 value, the lower the effectiveness of antioxidants and vice versa. These findings suggest that the antioxidant activity of EBNs extracts is relatively weak when compared to ascorbic acid. This study contributes to the understanding of optimized extraction techniques by heating and sonication to unlock the full potential of the extraction results of bioactive compounds.

Abstract

Communities living near forested areas play a crucial role in preserving forest biodiversity. Ethnomycological studies are an important first step in identifying the variety and potential of macrofungi used by people in a region. This study aims to document the use of macrofungi by the local community around Sesaot forest. The collection and identification of macrofungi samples were carried out using opportunistic sampling. Data on the use of macrofungi was obtained from semi-structured interviews with residents around Sesaot Forest. A total of 26 respondents from the Sesaot community participated in the survey. The people usually collected macrofungi for consumption and occasionally for medicinal purposes. The results identified 12 species of macrofungi from 10 families (Pezizaceae, Auriculariaceae, Sarcoscyphaceae, Gomphaaceaae, Pleurotaceae, Ganodermataceae, Psathyrellaceae, Polyporaceae, Agaricaceae, and Nidulariaceae) in Sesaot forest. Auricularia sp. and Pleurotus sp. were used as food, while Lignosus sp. was used as medicine by the local people in Sesaot.

Abstract

In this study, sampling was carried out at 3 locations of swallow nest farmers, namely in East Lombok, Central Lombok and West Lombok. The type of swallow nest used in this study was the Linchi swallow nest. This study was a quantitative study, namely to find the best variation in soaking time with alkaline water and Oxygen Water to reduce nitrite levels. Sample measurement using a Uv-Vis spectrophotometer instrument and characterization using FTIR. The results of the study showed the highest reduction in nitrite levels using an alkaline solvent with a pH of 7.5, Central Lombok, East Lombok and West Lombok Edible Bird’s Nest Sample, respectively, as follows: 87.88%; 96.26%; and 94.59% with an optimum contact time of 30 minutes. While the highest reduction in nitrite levels for Central Lombok, East Lombok and West Lombok, Edible Bird’s Nest samples were as follows: 92.51%; 98.5%; and 97.85% with an optimum contact time of 15 minutes. This is also supported by FTIR spectra data from optimum conditions for reducing nitrite levels where the characteristics of the FTIR spectra in the 1400 cm-1 wavenumber region have a %T value after treatment> to %T before treatment. The results of the macronutrient test showed that the bird's nest contains carbohydrates, proteins and lipids. While the results of the phytochemical test showed that the bird's nest sample contained phenolic compounds. In this study, it has been successfully reduced nitrite levels in bird's nests using alkaline solvents pH 7.5 and Oxygen Water which is the latest method that is cheaper and more efficient.
