The effect of adding Kaempferia galanga on different dosages of artificial feed on the growth of milk fish seed (Chanos chanos)

Abstract

This research was carried out from 25th October to 5th December 2021 at the Brackish and Marine Water Laboratory, Faculty of Fisheries, Pekalongan University. The purpose of this study was to determine the effect of adding kencur (Kaemferiagalanga) to feed on milkfish growth. The study used laboratory experimental methods with 4 treatments and 3 replications. The treatments used were A (0% or feed without kencur), B (2% kencur powder/100g feed), C (4% kencur powder/100g feed) and D (6% kencur powder/100g feed). The results showed that treatment B gave the highest growth yield of 8.59g, followed by treatment C 4.95g, treatment D 3.78g and the lowest was treatment A, namely 3.78g. After analyzing the variance, the results of the F count are greater than the F table, which means that the addition of kencur to feed has an effect on the growth of milkfish. Survival rate of fish during treatment for all treatments was 100%. The water quality during the study was still within a reasonable range, namely temperature 28 -30 C, salinity 18-20 ppt, pH 7.5-7.9 and DO 4.6 - 5 ppm.Keyword: Milkfsih, Kaempferia galanga, Growth

Effect of turmeric probiotics on the survival rate and growth of domesticated endemic betta fish (Betta dennisyongi)

“…Turmeric also contains the compound curcumin, which has the function of increasing the absorption of food substances, which is done by stimulating the walls of the gallbladder to release bile into the small intestine, thereby improving digestion [18]; [19]. Turmeric also contains vitamin C [20]; [21], which functions as a catalyst that can speed up reactions in the body so that it can absorb and utilize it for growth [22]. Apart from that, the probiotic content in the treatment also helps increase food absorption in the fish's intestines.…”

Pengaruh penambahan tepung kunyit (Curcuma longa Linn.) terhadap pertumbuhan dan rasio konversi pakan ikan kakap putih (Lates calcarifer, Bloch)

“…Senyawa-senyawa ini memiliki efek positif terhadap pertumbuhan maupun kesehatan ikan. Herbal yang mengandung saponin, flavonoid dapat digunakan untuk meningkatkan nafsu makan sehingga mempengaruhi pertumbuhan (Linayati et al, 2022a). Kurkumin dilaporkan dapat meningkatkan pencernaan lemak, karbohidrat dan protein sehingga penyerapan zat-zat makanan meningkat (Arifin et al, 2016).…”

“…Serta didukung dengan pendapat Putri et al, (2017), bahwa kurkumin memiliki fungsi meningkatkan penyerapan zat-zat makanan yang dilakukan dengan merangsang dinding kantung empedu untuk mengeluarkan cairan empedu ke dalam usus halus sehingga meningkatkan pencernaan. Tepung kunyit dilaporkan juga mengandung vitamin C (Agustin et al, 2020), yang berfungsi sebagai katalisator yang dapat mempercepat reaksi dalam tubuh, sehingga mampu menyerap dan memanfaatkannya untuk pertumbuhan (Linayati et al, 2022a)…”
