Abstrak

Abstrak Daphnia sp. adalah salah satu pakan alami yang diberikan sebagai pakan benih ikan air tawar. Penyediaan pakan alami pada kegiatan pembenihan ikan air tawar masih sangat kurang karena kebutuhan pakan alami sebagian besar masih dipenuhi dari menangkap di alam. Penggunaan limbah hasil produksi kopi memiliki kandungan bahan organik yang belum termanfaatkan diharapkan sebagai media kultur dapat memenuhi kebutuhan akan Daphnia sp. penelitian ini bertujuan untuk mengetahui pengaruh pemberian kulit kopi sebagai pengkaya dalam budidaya Daphnia. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL), dengan penambahan kulit kopi yang berbeda yaitu 3 gr/l, 5 gr/l, 7 gr/l dan 9 gr/l. Peningkatan populasi Daphnia sp. dianalisis ragam dengan selang kepercayaan 95 %. Hasil penelitian menunjukan bahwa rata-rata populasi Daphina sp. pada penambahan kulit kopi yang berbeda memberikan pengaruh yang berbeda nyata (P < 0.05) terhadap kelimpahan populasi Daphina sp. pada Media kultur dengan penambahan kulit kopi 3 gram/liter memberikan hasil paling baik terhadap kelimpahan populasi Ddaphina sp. dengan jumlah populasi tertinggi terjadi pada hari ke-9 sebanyak 1 500 ekor. Kata kunci : Kulit Kopi media kultur, pertumbuhan, populasi, dan Daphnia sp. Abstract Daphnia sp. is one of the live food used for freshwater fish feed. The supply of live food in freshwater fish hatchery activities is still lacking due to most live food needs are obtained in the wild. The use of coffee production wastes containing organic materials that has not been utilized as a nutrient source in Daphnia sp culture can be exocarp to meet the needs of Daphnia sp. This study aims to determine the effect of coffee exocarp to increase Daphnia sp. population. The method used is a Complete Randomized Design (CRD), with the addition of different coffee exocarp ie 3 g/l, 5 g/l, 7 g/l and 9 g/l. The increase of Daphnia sp. population were analyzed with 95% confidence interval range. The results showed that the average population on different coffee exocarp addition gave a significantly different effect (P <0.05) of population abundance Daphnia sp. in culture media with 3 g/l coffee exocarp addition gives the best results on population abundance Daphina sp. with a population peaked at day-9 as much as 1500 organisns. Key words: Daphnia sp, coffee exocarp culture media, growth and population.
