Abstract

This investigation means to decide the impact on the development of goldfish seeds when taken care of pellets, to decide the impact on the development of goldfish seeds when taken care of with Lemna, and to decide the impact on the development of goldfish seeds when taken care of with a blend of pellets and Lemna. The exploration was directed from March - June 2020, at the Fish Seed Center, Bahorok District, Dusun VI, Timbang Jaya Village. Taking care of treatment A (100% pellets without giving lemna), Treatment B (75% pellets and 25% lemna), Treatment C (25% pellets and 75% lemna), Treatment D (half pellet feed and half lemna), Treatment E (100% lemna without pellets). The outcomes showed that the mix of pellet and lemna feed with a proportion of half pellets and half lemna significantly affected outright development, supreme weight, every day development rate, feed transformation rate, endurance rate, and water nature of goldfish (Cyprinus carpio).

Abstract

Araceae merupakan salah satu famili tumbuhan yang mengandung talas yang bercirikan memiliki batang lembab dan bunga kompleks yang tersusun atas spathe yang menutupi tongkolnya (spadix). Tujuan dari penelitian ini adalah untuk mengidentifikasi berbagai jenis tumbuhan Araceae yang terdapat di Hutan Sibayak II Sumatera Utara, serta indeks keanekaragaman tumbuhan Araceae dan keunggulan yang ditawarkan tumbuhan tersebut. Penelitian ini menggunakan pendekatan kuadran dan setiap plot berukuran 5 x 5 meter. Hasil penelitian menunjukkan bahwa jenis tumbuhan Araceae yang ditemukan terdiri dari 17 jenis yaitu: Homolomena pendula (Blume) Bakh.f., Anadendrum microstachyum (de Vriese Miq.) Backer Alderw., Rhapihidophora korthalshii Schott, Epipremnum pinnatum (L.) Engl., Rhapihidophora montana (Blume) Schott, Colacasia esculenta (L.) Schott, Amydrium humile Schott, Homolomena humilis (Jack) Hook.f., Scindapsus hederaceus Miq., Schismatoglottis trivittata Hallier, Arisaema filiforme (Reinw.) Blume, Schismatoglottis calyptra (Roxb.) Zoll. Moritzi, Alocasia macrorrhizoz (L.) G.DON, Schismatoglottis wallichii Hook.f., Xanthosoma robustum Schott, Alocasia longiloba Miq., Amorphophallus beccarii Engl., Meskipun tumbuhan anggota famili Araceae ini dimanfaatkan sebagai tanaman hias, komponen pangan, dan tanaman obat, namun keanekaragaman famili Araceae di Kawasan Hutan Sibayak II termasuk dalam kategori sedang. Hal ini menunjukkan bahwa anggota famili tumbuhan Araceae bersifat tangguh. Hal ini menunjukkan bahwa ekosistem beroperasi dalam kondisi yang agak seimbang. Indeks keanekaragaman tumbuhan pada famili Araceae sebesar 2,37.
