Abstract

 AbstrakPenggunaan biji tumbuhan yang mengandung protein tinggi sebagai bahan substitusi tepung ikan dalam pelet telah beberapa dilakukan. Tujuan dari penelitian ini adalah untuk mengetahui pertumbuhan dan kelangsungan hidup ikan patin (Pangasius sp.) setelah pemberian pakan bersubstitusi biji Terminalia catappa L. selama 12 minggu sebanyak 120 ekor ikan yang diberi pakan variasi substitusi tepung ikan: 0% (kontrol), 10, 15, dan 20%. Pertambahan bobot ikan (BWG), penambahan berat harian (DWG), pertambahan bobot mingguan (AWG), laju pertumbuhan relatif harian (SGR), pertambahan panjang total (LG), konversi pakan (FCR), efisien pakan (FE), dan kelangsungan hidup (SR) diukur setiap minggu. Hasil penelitian menunjukkan bahwa substitusi biji 10–20% dibandingkan dengan kontrol tanpa substitusi tidak ada beda nyata dalam parameter BWG, DWG, AWG, SGR, LG, FE dengan nilai tertinggi pada perlakuan 15% (P2) dan FCR 20% (P3). Sementara, SR berkisar 83,33–100%. Biji Ketapang dapat digunakan sebagai substitusi tepung ikan antara 10–20% untuk pertumbuhan dan kelangsungan hidup ikan yang optimum.AbstractThe use of nut plant which contains high protein level as a substitution for fish meal in the diet of fish has been performed in some researches. This study was conducted to determine the growth and survival of catfish (Pangasius sp.) fed ketapang (Terminalia catappa L.) seeds substitution for fish meal in their test diet for 12 weeks. The aquarium contained 120 fish that fed various concentrations of substitution with ketapang seeds in the test diet, vis: 0% (control), 10, 15, and 20%. Fish weight gain (BWG), daily weight gain (DWG), weekly weight gain (AWG), relative daily growth rate (SGR), total fish length (Length gain), feed conversion (FCR), feed efficiency (FE), and survival (SR) were measured every week. The results showed that 10 to 20% ketapang seed substitution compare to control had no significant effect in term of  BWG, DWG, AWG, SGR, Length gain. The highest FE was achieved at 15% substitution while FCR 20%. The SR showed the percentage ranges from 83.33–100%. This study concluded that ketapang seed can be used as a fish meal substitution from 10–20% for optimum growth and survival of catfish.

Abstract

Background: Indian almond (Terminalia catappa) is used as an alternative medicine by the community to treat various diseases. However, limited research has been conducted on the subchronic toxicity of Indian almond water extracts on the liver. Present study aimed to determine the subchronic toxic effects of Indian almond leaf water extract on the liver histology of mice and to evaluate the safe dose of Indian almond leaf water extract with various doses (125, 250, 500, 750 and 1000 mg/kg). Methods: In total of 33 male mice were randomly divided into 11 groups, each group consisting of three mice as replication. For 30 days, mice in five treatment groups were orally treated every day with water extracts of green Indian almond leaf while other five groups were given water extracts of brown Indian almond leaves and compare with control group. At the end of day 30, all mice were sacrificed, and hepar was taken out for histological preparations. The histopathological changes in the liver was observed and assessed based on histological damage in the term of degeneration and necrosis. Results: The administration of green and brown Indian almond water extract at doses of 125, 250, 500, 750 and 1000 mg / kg BB showed a toxic effect on the liver of mice. The toxic effect was due to the high doses, causing a cell swelling damage and increased liver necrosis. Conclusion: Indian almond leaf water extract can cause toxic effects on the liver of mice at the doses implemented.
