Skripsi, Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Malang. Pembimbing : (I) Drs. Agus Dharmawan, M. Si., (II) Agung Witjoro, S. Pd., M. Kes. Kata Kunci : Ikan Lele Masamo (Clarias sp.), Pakan Alami (Fitoplankton), Sistem Bioflok, Padat Penebaran, Pertumbuhan biomassa, Kualitas Air. Produksi dalam budidaya ikan lele Masamo (Clarias sp.) sangat tergantung dengan ketersediaan pakan yang kualitas dan kuantitasnya sangat mempengaruhi hasil produksi. Sistem bioflok padat tebar dalam budidaya ikan lele Masamo merupakan salah satu alternatif dalam mengatasi permasalahan ketersediaan pakan. Penelitian ini bertujuan untuk mengetahui pertumbuhan biomassa ikan lele Masamo dalam budidaya sistem bioflok dengan padat penebaran 1000 ekor/m2 dan pengambilan sampel 7 hari sekali selama 42 hari sebanyak 50 ekor setiap kolam. Pengambilan data dilakukan dengan mengukur biomassa ikan lele Masamo, kerapatan pakan alami, dan kualitas air (suhu, oksigen terlarut, kekeruhan, dan derajat keasaman) Hasil Uji anava tunggal menunjukkan pertumbuhan biomassa ikan selama 5 minggu dengan pertumbuhan biomassa paling signifikan di minggu ke-5. Hasil Uji korelasi menunjukkan hubungan kerapatan pakan alami terhadap pertumbuhan biomassa ikan lele Masamo adalah negatif dengan pengertian peningkatan biomassa ikan lele Masamo diiringi dengan penurunan pakan alami. Hasil uji regresi menunjukkan bahwa kualitas air mempengaruhi pertumbuhan biomassa ikan lele Masamo, khususnya kekeruhan

This work makes use of observations from the LCOGT network, which includes three SUPAscopes owned by the University of St Andrews. The RoboNet programme is an LCOGT Key Project using time allocations from the University of St Andrews, LCOGT, and the University of Heidelberg together with time on the Liverpool Telescope through the Science and Technology Facilities Council (STFC), UK. This research has made use of the LCOGT Archive, which is operated by the California Institute of Technology, under contract with the Las Cumbres Observatory.We report the detection of a cold Neptune mplanet = 21 ± 2 M⊕ orbiting a 0.38 M⊙ M dwarf lying 2.5-3.3 kpc toward the Galactic center as part of a campaign combining ground-based and Spitzer observations to measure the Galactic distribution of planets. This is the first time that the complex real-time protocols described by Yee et al., which aim to maximize planet sensitivity while maintaining sample integrity, have been carried out in practice. Multiple survey and follow up teams successfully combined their efforts within the framework of these protocols to detect this planet. This is the second planet in the Spitzer Galactic distribution sample. Both are in the near to mid-disk and are clearly not in the Galactic bulge.Peer reviewe
