Abstract

Nilai jual yang tinggi menyebabkan produksi ikan guppy jantan lebih menguntungkan. Teknik sex reversal menggunakan bahan alami seperti air kelapa sudah dilakukan dalam usaha untuk menghasilkan ikan guppy jantan lebih banyak. Kalium pada air kelapa mendukung pembentukan hormon androgen atau testosterone. Penelitian ini bertujuan untuk mendapatkan metode yang paling efektif dalam pembentukkan jenis kelamin jantan menggunakan air kelapa muda jenis Cocos nucifera. Penelitian menggunakan rancangan acak lengkap dengan 3 perlakuan dan 3 ulangan. Perlakuan berupa kontrol tanpa pemberian air kelapa (A), perlakuan secara oral melalui pakan pada induk bunting dengan dosis 10% bobot pakan (B) selama 14 hari, dan perlakuan melalui perendaman induk bunting dengan dosis 10% volume air selama 12 jam. Pengamatan kelamin jantan dilakukan setelah 45 hari pemeliharaan dengan mengamati organ urogenital. Hasil penelitian menunjukkan bahwa persentase jantan tertinggi diperoleh pada perlakuan B (65,33%± 4,50b), diikuti perlakuan C (51,33%± 9,60ab) dan terendah pada perlakuan A (41,67%±2,08a). Persentase kelangsungan hidup tidak berbeda nyata antar perlakuan dengan tingkat kelangsungan hidup berkisar 77,33 – 88,00%.The high selling value causes the production of male guppies to be more profitable. Sex reversal techniques using natural ingredients such as coconut water have been carried out in an effort to produce more male guppy fish. Potassium in coconut water supports the formation of androgen hormones or testosterone. This study aims to get the most effective method in the formation of male sex using young coconut water type Cocos Nucifera. The study used a random design complete with 3 treatments and 3 replications. Treatment is in the form of control without coconut water (A), oral treatment through feed on pregnant parent with a dose of 10% feed weight (B) for 14 days, and treatment through the maternal soaking with a dose of 10% volume of water for 12 hours. Observation of male sex is carried out after 45 days of maintenance by observing the urogenital organs. The results showed that the highest percentage of male was obtained in treatment B (65.33%± 4.50b), followed by treatment C (51.33%± 9.60ab) and the lowest in treatment A (41.67%± 2.08a). The percentage of survival is not significantly different between treatments with survival rates ranging from 77.33 - 88.00%.

Abstract

The production of male guppies is more desirable due to it higher selling value than females. One way to produce male guppies is change it sex, namely masculinization which can be enhanced through the addition of coconut water, with high potassium level. Potassium can convert all cholesterol in the larvae into pregnenolone, which functions to convert estrogen into progesterone and produces testosterone. Hormones required in sex change can be supplemented by the oral method through feed. The research, which was conducted from November 2022 - March 2023, was divided into two stages, first is to determine the dosage of coconut water and the second one is to determine the appropriate coconut water sterilization method. Each stage used a completely randomized design with four treatments and four replicates. Doses of coconut water added to feed were 0.06 ml/g feed, 0.09 ml/g feed, 0.12 ml/g feed, and 0.15 ml/g feed. The sterilization methods conduct in this research are using UV light, autoclave, and ozone. Observation of male genitalia was done after 45 days by observing the urogenital organs and confirmed by hematoxylin-eosin histological staining after 52 and 59 days. The highest percentage of male guppies at 71.75% was produced by the dose of 0.15 ml/g feed, while sterilization treatment produces lower male percentage than control (p<0.05).  No significant difference in fish survival was obtained. Fish survival ranges from 88% - 93%. Thus, the addition of 0.15 ml of coconut water to feed is the most effective treatment in producing male guppies.

Abstract

Dragon fruit skin contains betacyanin, a pigment responsible for the red color. Red dragon fruit skin can be used as a flour ingredient in artificial feed containing carotenoids, which is useful for enhancing the color of ornamental fish. The aim of this research is to determine the effect of using red dragon fruit peel flour concentration in feed on improving the color of koi betta fish. The research implementation period was 55 days from October 6 to November 27, 2025, including 1 week pre-research, 3 days without test feed and 45 days of research. The test fish used in the study were 12 koi betta fish, with four treatments and three replications. The test material used was red dragon fruit peel powder added to the betta feed. The addition of red dragon fruit peel flour in feed for koi betta fish shows an increase in the brightness of different colors, this is due to the different doses given in the feed. The highest color enhancement was achieved at doses of 20% and 30%. Adding red dragon fruit peel powder to the feed is well absorbed by the fish, resulting in an increase in the brightness of the koi betta's color. The survival rate of koi betta fish for 45 days for all treatments was 100%.

Abstract

Secara umum, ikan nila jantan menunjukkan pertumbuhan lebih pesat dibandingkan betina sehingga dapat mempercepat waktu pemanenan. Upaya peningkatan proporsi kelamin jantan dapat dilakukan melalui teknik maskulinisasi sehingga ikan betina terdiferensiasi kelaminnya menjadi jantan. Kandungan kalium dalam air kelapa berpotensi menggantikan fungsi hormon sintetis 17α metil testosteron dan dinilai lebih ramah lingkungan karena bersumber dari bahan alami. Penelitian ini bertujuan menentukan dosis air kelapa yang optimal untuk meningkatkan persentase kelamin jantan dan mempertahankan tingkat kelangsungan hidup larva ikan nila. Penelitian disusun menggunakan rancangan acak lengkap dengan 4 perlakuan dan 3 ulangan, terdiri atas kontrol tanpa penambahan air kelapa serta penambahan air kelapa 0,09 mL/g pakan, 0,12 mL/g pakan, dan 0,15 mL/g selama 14 hari dengan menggunakan ikan sebanyak 30 ekor/akuarium dengan total akuarium 12 buah dengan bobot rata-rata ± 0,01 gr/ekor. Pengamatan terhadap kelamin jantan dilakukan setelah 60 hari. Data dianalisis menggunakan ANOVA satu arah (α = 0,05) dan dilanjutkan dengan uji Duncan menggunakan SPSS versi 26. Hasil penelitian menunjukkan bahwa penambahan air kelapa. Penambahan air kelapa 0,15 mL/g pakan merupakan dosis paling optimal dengan persentase kelamin jantan sebesar 67,05±1,75. Variasi dosis air kelapa dalam pakan tidak menimbulkan perbedaan pengaruh terhadap tingkat kelangsungan hidup yang berada pada kisaran 93-100%.
