“…The activity of the extract against A. hydrophila showed the highest response. This indicates that the red seaweed hexane extract H. durvillei has promising potential as an antibacterial agent, especially against pathogenic bacteria A. hydrophila causes disease and crop failure in cultured fish (Rozi et al, 2018). The results of this study are supported by the report of Vinosha et al (2020) that the sulfate galactan component Halymenia sp., besides having antioxidant activity, is also able to increase the resistance of fish Oreochromis against bacteria Aeromonas hydrophilic.…”

This study aimed to determine the antibacterial activity and toxicity of methanol and hexane extracts of Halymenia durvillei red seaweed which were found abundantly in Kayangan island, South Sulawesi. The antibacterial activity of the crude extract was tested against five gram-negative bacteria, namely Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, Aeromonas hydrophila, and Vibrio harveyi at a dose of 200 g/disk. Extract toxicity was tested on Artemia salina larvae at concentrations of 1,000, 500, 250, 125, 62.5, and 31.25 µg/mL. The results showed that the methanol and hexane extracts of H. durvillei had the highest activity against S. thypi and A. hydrophila, respectively, with inhibition zones of 26.2 mm and 21.0 mm. On the other hand, the two extracts did not show activity against E. coli and P. aeruginosa, respectively. The toxicity of the methanol extract of H. durvillei was twice as high as that of the hexane extract with half-maximal inhibitory concentration of 98.24 and 184.21 µg/mL, respectively. Thus, the methanol and hexane extracts of red seaweed H. durvillei have the potential as new antibacterial agents respectively against the pathogenic bacteria S. typhi and A. hydrophila, but also have the opportunity to be developed into antitumor herbal compounds.

“…Jika dilihat FCR tertinggi pada penelitian ini masih berada pada angka 7,27 sehingga perolehan nilai FCR ini lebih rendah. Hal ini menandakan bahwa pakan yang diberikan selama masa pemeliharaan dapat dicerna dengan optimal oleh ikan sehingga dapat menambah massa dagingnya (Rozi, 2018). Semakin kecil FCR yang didapatkan maka pakan yang diberikan semakin efisien untuk pertumbuhan ikan nila merah yang dipelihara.…”

Feed is one of the most important aspects that cannot be left out in the fish farming process. One of the problems often faced by cultivators is the high price of feed due to the use of imported raw materials, such as soybean meal flour. To reduce the use of soybean meal flour, a new innovation was carried out in the form of substitution of local raw materials, namely Indigofera sp. This study aims to determine the effect of TDI (Indigofera sp.) as a substitute for soybean meal flour on growth performance on rearing red tilapia (Oreochromis sp.). This study used a completely randomized design with 4 treatments and 3 replications. P1 (without TDI usage), P2 (10% TDI usage), P3 (20% TDI usage), P4 (30% TDI usage). The data obtained were analyzed using analysis of variance (ANOVA) then further tested with Duncan's test. Based on statistical analysis, the test feed had a significant effect (p<0.1) on FCR was not significantly different (p>0.1) on the growth of absolute weight, absolute length, SGR, and SR of fish. The result of this study is that the use of TDI (Indigofera sp.) can be used up to a dose of 30% as a substitute for soybean meal flour in red tilapia feed, because it produces the same absolute weight growth, absolute length growth, SGR, and SR as the control feed.

“…Nilai konversi pakan ikan dengan pemberian pakan C (3.09) memiliki nilai rasio konversi pakan paling baik dibandingkan dengan ikan yang diberi pakan D (4.09) yang memiliki nilai rasio konversi pakan paling tinggi. Lebih baiknya nilai konversi pakan (pada perlakuan C), menandakan bahwa pakan yang diberikan pada benih ikan nila mampu dimanfaatkan dengan baik untuk pertumbuhan Rozi et al, (2019), sedangkan pada perlakuan D konversi pakannya paling tinggi. NRC (1997) melaporkan bahwa pertumbuhan ikan cenderung menurun apabila diberi pakan dengan kandungan serat kasar yang meningkat.…”

Ikan nila merupakan ikan omnivora yang membutuhkan sumber protein yang berasal dari protein nabati dan hewani untuk keseimbangan nutrisinya. Penggunaan bahan baku dari daun talas dan limbah ikan rucah, dapat menjadi alternatif pakan yang murah, mudah di dapat, namun memerlukan kajian mengenai rasio penggunaannya dalam formulasi pakan buatan. Riset ini bertujuan untuk menganalisis efektivitas penggunaan daun talas (Colocasia esculenta) dan kombinasinya dengan tepung ikan rucah subtusi pada ikan nila (Oreochromis niloticus). Penelitian dilakukan secara eksperimental dengan Rancangan Acak Lengkap (RAL 4×4), terdiri dari penggunaan tepung daun talas (DT) dan subtitusi tepung ikan oleh tepung ikan rucah (IR), yaitu A (kontrol), B (15% DT), C (20% DT + tepung ikan rucah subtitusi 50%), dan D (25% DT + tepung ikan rucah subtitusi 100%). Hasil analisis menunjukkan bahwa penggunaan DT dan IR, tidak berefek negatif terhadap kelangsungan hidup ikan dan kualitas air. Rasio konversi pakan dan efisiensi pakan terbaik diperoleh pada perlakuan C (20% DT dengan subtitusi 50% IR),yaitu masing-masing sebesar 3,09 ± 0,098 dan 32,36 ± 1,089 sehingga dapat digunakan sebagai sumber protein pakan pengganti bungkil kedele dan tepung ikan pada ikan nila.
