Aplikasi Hormon 17a-Metiltestosteron (MT) dalam Proses Maskulinisasi Ikan Killifish Guentheri Red Nothobranchius guentheri Rahman, Riem Rahayu Ikan killifish guentheri red (Nothobranchius guentheri) merupakan ikan hias air tawar bernilai ekonomis tinggi, karena warna tubuh ikan jantan lebih menarik dibandingkan betina. Tujuan penelitian ini untuk mengevaluasi penggunaan hormon 17a-metiltestosteron terhadap persentase ikan jantan, sintasan, dan tingkat abnormalitas. Penelitian menggunakan hormon 17a-metiltestosteron (MT) dengan rancangan acak lengkap dengan 4 perlakuan dan 3 ulangan, yaitu H0 (tanpa hormon), H1 (5 mg L-1), H2 (10 mg L-1), dan H3 (15 mg L-1) melalui perendaman larva selama 6 jam. Hasil menunjukkan bahwa pemberian hormon MT berpengaruh signifikan (P<0,05) terhadap persentase ikan jantan dan sintasan, namun tidak berpengaruh signifikan (P>0,05) terhadap tingkat abnormalitas. Persentase ikan jantan tertinggi diperoleh pada perlakuan H2 sebesar 91,83±8,61% dan sintasan tertinggi pada perlakuan H0 sebesar 76,33±2,36%. Tingkat abnormalitas ikan hanya ditemukan pada perlakuan H3 sebesar 0,33±0,29%. Dosis hormon 10 mg L-1 merupakan dosis paling efektif dalam meningkatkan persentase ikan jantan.; Killifish guentheri red (Nothobranchius guentheri) is a freshwater ornamental fish with high economic value due to the more attractive coloration of males compared to females. This study aimed to evaluate the application of 17a-methyltestosterone (MT) on male percentage, survival rate, and abnormality rate. The experiment was conducted using a completely randomized design with four treatments and three replications, namely H0 (without hormone), H1 (5 mg L-1), H2 (10 mg L-1), and H3 (15 mg L-1) applied through larval immersion for 6 hours. The results showed that MT administration had a significant effect (P<0,05) on male percentage and survival rate, but no significant effect (P>0,05) on abnormality percentage. The highest percentage of male fish was obtained in treatment H2 at 91,83±8,61% and the highest survival rate was observed in H0 at 76,33±2,36%. Abnormalities were only found in H3 at 0,33±0,29%. The dose of 10 mg L-1 was the most effective in increasing the percentage of male fish.

Efektivitas Pemberian Probiotik Melalui Pakan Terhadap Produksi Udang Vaname Litopenaeus vannamei Di Tambak. Firdaus, Irhandhi Maulana Penelitian ini bertujuan untuk mengetahui efektivitas pemberian probiotik melalui pakan terhadap pertumbuhan dan produksi udang vaname (Litopenaeus vannamei). Metode yang digunakan yaitu ex post facto dengan tiga perlakuan, yaitu P1 (kontrol tanpa probiotik), P2 (penambahan probiotik 125 mL/L), dan P3 (penambahan probiotik 200 mL/L). Probiotik yang digunakan mengandung bakteri Bacillus sp. dan Lactobacillus sp. yang dicampur ke dalam pakan dan difermentasi selama 24 jam. Hasil penelitian menunjukkan bahwa pemberian probiotik melalui pakan memberikan pengaruh nyata terhadap pertumbuhan dan efisiensi pakan udang vaname. Perlakuan P3 menghasilkan performa terbaik untuk biomasa, LPH dan FCR dibandingkan perlakuan lainnya. Dosis probiotik 200 mL/L direkomendasikan untuk diterapkan pada skala budidaya komersial.; This study aimed to determine the effectiveness of probiotic supplementation through feed on the growth and production of whiteleg shrimp (Litopenaeus vannamei). The research employed an ex post facto method with three treatments: P1 (control without probiotics), P2 (addition of 125 mL/L probiotics), and P3 (addition of 200 mL/L probiotics). The probiotics used contained Bacillus sp. and Lactobacillus sp., which were mixed into the feed and fermented for 24 hours. The results showed that probiotic supplementation through feed had a significant effect on the growth and feed efficiency of L. vannamei. The P3 treatment produced the best performance in terms of biomass, specific growth rate (SGR), and feed conversion ratio (FCR) compared to other treatments. A probiotic dosage of 200 mL/L is recommended for application in commercial, scale aquaculture.

Pencegahan Infeksi Fungi pada Telur Ikan Manfish dengan Methylene Blue dan Ekstrak Daun ketapang

Pencegahan Infeksi Fungi pada Telur Ikan Manfish dengan Methylene Blue dan Ekstrak Daun ketapang Afifuddin, Aisyah Ekaputri Ikan manfish salah satu ikan hias yang banyak diminati oleh penghobi di Indonesia, namun terdapat permasalahan yaitu infeksi fungi pada telur ikan manfish. Penelitian terapan ini bertujuan untuk mendapatkan bahan terbaik yang dapat mengendalikan infeksi fungi pada telur ikan manfish. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari tiga perlakuan dan tiga ulangan yaitu Kontrol (tanpa pemberian bahan), A (pemberian methylene blue 0,46 mL/L), dan B (pemberian ekstrak ketapang 0,46 mL/L). Hasil penelitian diperoleh bahwa pemberian ekstrak daun ketapang perlakuan B, menghasilkan nilai tertinggi pada derajat pembuahan 91%, derajat penetasan 96%, dan tingkat kelangsungan hidup 79% dibandingkan dengan perlakuan lainnya. Namun demikian, secara statistik semua perlakuan tidak berbeda nyata (P>0,05). Kata kunci: ekstrak daun ketapang, methylene blue, fungi, ikan manfish; The manfish is one of the highly sought-after ornamental fish in Indonesia; however, a problem with fungal infections in manfish eggs has been identified. This applied research aims to identify the most effective materials for controlling fungal infections in manfish eggs. The study employed a Completely Randomized Design (CRD) comprising three treatments and three replications: Control (without treatment), A (methylene blue at 0.46 mL/L), and B (ketapang leaf extract at 0.46 mL/L). The test material in this study was manfish eggs. Based on the research results, the application of ketapang leaf extract yielded the highest values for fertilization rate (91%), hatching rate (96%), and survival rate (79%), compared to the other treatments. However, statistically, no significant differences were observed among all treatments (P > 0.05). Keywords: ketapang leaf extract, methylene blue, fungal, manfish

Efektifitas Minyak Pala Myristica Fragrans Pada Transportasi Benih Ikan Nila Oreochromis niloticus

2025-09-18T08:49:45Z

Efektifitas Minyak Pala Myristica Fragrans Pada Transportasi Benih Ikan Nila Oreochromis niloticus Aldiyasfa, Mohammad Devan Ikan nila merupakan ikan komoditas air tawar yang banyak diminati masyarakat karena kualitas dan protein yang terkandung dalam ikan tersebut sangat besar, akan tetapi penanganan transportasi yang salah dalam proses pengiriman ikan dapat menyebabkan berkurangnya kualitas ikan tersebut. Hal tersebut dapat ditangani dengan penggunaan bahan aktif yang dapat meredakan stress pada ikan saat perjalanan dengan cara membuat ikan lemas dan bergerak perlahan sehingga akhirnya pingsan. Minyak atsiri pala memiliki bahan aktif yaitu Myristicin yang termasuk kedalam jenis alkohol sehingga dapat memiliki fungsi tersebut. Penelitian menggunakan metode rancangan acak lengkap dengan empat perlakuan A) Penggunaan minyak pala dengan dosis 0,8 ppm, B) Minyak paka dengan dosis 0,9 ppm, C) Minyak pala dengan dosis 1,1 ppm, D) Tanpa penambahan perlakuan, dan tiga kali ulangan. Hasil dari penelitian penggunaan minyak atsiri pada proses transportasi ikan adalah didapati bahwa perlakuan D mendapatkan SR paling tinggi sebanyak 80%, lama waktu pingsan paling lama 300 menit 50 detik, serta lama waktu sadar paling lama yaitu 70 menit. Kata kunci : Benih, minyak pala, transportasi Tilapia is a freshwater commodity fish that is in great demand by the public because the quality and protein contained in this fish is very large, however, incorrect transportation handling in the process of sending fish can cause a reduction in the quality of the fish. This can be handled by using active ingredients that can relieve stress on fish during travel by making the fish limp and move slowly so that they eventually faint. Nutmeg essential oil has an active ingredient, namely Myristicin, which is a type of alkohol so it can have this function. The study used a completely randomized design method with four treatments A) Using nutmeg oil at a dose of 0.8 ppm, B) Nutmeg oil at a dose of 0.9 ppm, C) Nutmeg oil at a dose of 1.1 ppm, D) Without additional treatment, and three repetitions. The results of research on the use of essential oils in the fish transportation process were that treatment D was superior in the highest SR parameter of 80%, the longest time of unconsciousness was 300 minutes 50 seconds, and the longest time of consciousness was 70 minutes.
