Abstract

Pangasius sp. is one of the leading freshwater aquaculture commodities in Indonesia with high economic value and growing market demand. The success of Pangasius culture is largely determined by optimal growth performance, which in practice is often hampered even when farmers provide artificial feed. This study aims to examine the factors inhibiting the growth of Pangasius sp. fed artificial feed in pond culture systems and to formulate appropriate management solutions. A descriptive qualitative method with a literature review approach was applied to national scientific articles published within the last ten years. The results indicate that growth-inhibiting factors include low quality and digestibility of artificial feed, fluctuating water quality (temperature, pH, dissolved oxygen, and ammonia), stocking densities that exceed pond carrying capacity, inadequate feeding management, and pest or disease attacks. Recommended solutions include supplementing feed with exogenous enzymes (papain and protease) to improve protein digestibility, applying biopore and biofloc technologies to stabilize water quality, adjusting stocking density and feeding frequency to growth stages, utilizing probiotics and photosynthetic bacteria, and diversifying natural and local feed sources. Integrated application of these solutions is expected to improve feed efficiency, growth rate, and survival of Pangasius sp. in pond culture systems.

Abstract

Background. Coastal areas are among the most productive ecosystems on Earth, yet they are also among the most exposed to human carelessness, particularly the steady inflow of plastic waste. Aims. This activity was carried out to build the knowledge, attitude, and moral responsibility of young people toward coastal sustainability through the "Aquatic Ethics School: Learning to Protect Coastal Environments" program, held on 18 June 2026 at SMP Negeri 6 Idanogawo, Nias Regency, North Sumatra. Methods. The program combined interactive talks, small-group discussion, an open Q&A session, and a closing commitment declaration written and read by the students themselves. Before the session, most participants could not clearly connect everyday habits with the condition of the coast near their school; afterward, they were able to explain microplastic formation, the logic behind Reduce-Reuse-Recycle, and where they personally fit into the problem. Conclusion. The enthusiasm shown during discussion, together with the willingness to sign the commitment declaration, suggests that ethics-based environmental education can move students from passive awareness toward a felt sense of responsibility for the coastline they live beside.
