Abstract

This study aimed to evaluate the effect of fermented red galangal (Alpinia officinarum) extract on the pH value and index of quail eggs during storage. A total of 315 fresh quail eggs were subjected to three treatments: no immersion (P0), immersion in 25% extract (P1), and immersion in 50% extract (P2), using a completely randomized design with five replications. Eggs were immersed for 24 h and stored at room temperature for 0 to 49 days. Observations were conducted on days 0, 7, 14, 21, 28, 35, 42, and 49 for albumen pH, yolk pH, albumen index, and yolk index. The results showed that immersion in fermented red galangal extract significantly reduced the increase in pH of both albumen and yolk compared to the control, particularly at a concentration of 50%. The treatment also slowed the decline in albumen index and yolk index, with P2 consistently maintaining higher values throughout storage. Overall, immersion in 50% fermented red galangal extract was the most effective treatment, extending the internal quality of quail eggs for up to 49 days. This suggests that fermented red galangal extract has potential as a natural preservative for quail eggs, and further studies are recommended to assess microbiological quality and oxidative stability during storage.

Abstract

Dairy farmers from the Mulyo Farmers group, located in Mulyorejo Village, Sukun District, Malang City, are experiencing problems with feed productivity because dairy cows require fresh grass for their consumption. The cow dung on this farm has not been utilized properly, resulting in waste that can pollute the river flow in the surrounding environment. The purpose of this service is to provide solutions to these issues. The methods used in this service include socialization about the dangers of cow dung waste and its utilization, training in creating milk packaging with market value, and developing tools for shredding and drying cow dung. The results of this service activity indicate that farmers can save time and money on feed purchases by up to 30% because the grass can be chopped and consumed by all the cows. Additionally, cow dung can be dried and sold, increasing the income of the Farmers Group. Public knowledge about the dangers of cow dung and its utilization increased from level 2 to level 6, while awareness of dairy product packaging improved from 10% to 40%.
