      Abstract
      Ikan guppy Poecilia reticulata jantan memiliki nilai ekonomi lebih tinggi dibandingkan betina sehingga diperlukan upaya untuk meningkatkan proporsi ikan jantan melalui teknik maskulinisasi. Penelitian ini bertujuan mengevaluasi pengaruh perendaman larva menggunakan ekstrak cabe jawa Piper retrofractum terhadap nisbah kelamin ikan guppy. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan, yaitu kontrol, 2 mg L?¹, 4 mg L?¹, dan 6 mg L?¹, masing-masing tiga ulangan. Parameter yang diamati meliputi nisbah kelamin jantan, pertambahan panjang mutlak, sintasan, dan kualitas air. Hasil penelitian menunjukkan bahwa dosis 4 mg L?¹ memberikan hasil efektif dengan persentase ikan jantan sebesar 78%, pertambahan panjang mutlak 1,48 cm, dan sintasan 97% dibandingkan perlakuan lainnya. Kualitas air selama penelitian berada pada kisaran optimal untuk pemeliharaan ikan guppy. Pemberian ekstrak cabe jawa dengan dosis 4 mg L?¹ menghasilkan nisbah kelamin jantan, pertambahan panjang mutlak, dan sintasan. Disarankan menggunakan ekstrak cabe jawa dengan dosis 4 mg L?¹ sebagai bahan alami untuk meningkatkan nisbah kelamin jantan.
       
      Male guppies Poecilia reticulata possess Male guppies (Poecilia reticulata) have higher economic value than females, so efforts are needed to increase the proportion of male fish through masculinization techniques. This study aimed to evaluate the effect of immersing larvae in an extract of Javanese chili (Piper retrofractum) on the sex ratio of guppies. The study used a completely randomized design (CRD) with four treatments—control, 2 mg L?¹, 4 mg L?¹, and 6 mg L?¹—each with three replicates. The parameters observed included the male sex ratio, absolute length gain, survival rate, and water quality. The results showed that the 4 mg L?¹ dose was the most effective, yielding a male percentage of 78%, an absolute length gain of 1.48 cm, and a survival rate of 97% compared to the other treatments. Water quality throughout the study remained within the optimal range for guppy rearing. The administration of Javanese chili extract at a dose of 4 mg L?¹ resulted in improved male sex ratio, absolute length gain, and survival rate. It is recommended to use Javanese chili extract at a dose of 4 mg L?¹ as a natural agent to increase the male sex ratio.
