Abstract

Chicken feathers contain about 80–90% protein, but the keratin type is poorly digestible, requiring fermentation. This study aimed to analyze the effect of substituting fish meal with fermented feather meal on the growth and survival of barramundi (Lates calcarifer). The research was conducted from March 8 to April 5, 2025, at the Hatchery and Aquaculture Technology Laboratory, Malikussaleh University. A Completely Randomized Design (CRD) with five treatments and three replications was used: A (0%), B (5%), C (10%), D (15%), and E (20%) substitution levels of fermented feather meal. Parameters observed included feed response, absolute growth in length and weight, feed conversion ratio (FCR), survival rate (SR), water quality, and feed proximate and organoleptic tests. The results showed that substituting fish meal with fermented feather meal significantly affected growth and feed efficiency (P<0.05). The best results were obtained in treatment D (15%) with an average length of 2.02 cm, weight of 2.28 g, FCR of 1.56, and survival rate of 83.33%. Water quality parameters remained within optimal ranges: temperature 25.8–29.1°C, pH 7–8.8, DO 4.6–6.44 ppm, and salinity 15 ppt. Keywords: Barramundi; Chicken Feather Meal; Fermented; Feed; Growth

Abstract

Floods that occurred in Gampong Tanjung Punti at the end of 2025 were associated with changes in the psychosocial conditions of children as a vulnerable group. Initial observations revealed that some children appeared anxious, less socially interactive, and still displayed fear-related expressions when recalling the flood event. This situation served as the basis for implementing a community service program integrating trauma healing, basic needs fulfillment, and spiritual support. The program aimed to support psychosocial assistance for flood-affected children through a participatory and child-friendly approach involving 35 children aged 5–12 years, village officials, and local community members. Activities included the distribution of basic supplies and clothing, provision of Qur’an copies, and trauma healing sessions through educational games, drawing, storytelling, and simple relaxation exercises. The results of the activities indicated increased children’s participation, improved emotional expression, and a growing sense of safety during the sessions. In addition, basic needs support and spiritual assistance were perceived to help reduce community burdens in the early post-disaster phase. The holistic approach integrating psychosocial support, basic needs fulfillment, and spiritual dimensions indicates potential support for early recovery processes among flood-affected children and communities.
