    APAKAH BIAWAK AIR (Varanus salvator macromaculatus Deraniyagala, 1944) KARNIVOR?
    (wahyu sari yeni, 2019-07-22) Sholeh, Muhammad; Setyawatiningsih, Sri Catur
    Water monitor lizards are generally carnivores, but in a recent study of stomach water monitor lizards were found fragments of coconut meat. Therefore, it is necessary to describe the evidence of other water monitor lizards as carnivores. Observation of water monitor lizard digestive anatomy (tooth type, presence of caecum and ratio length of intestines to Snout Venth Length), and position of endoparasites in the digestive organs of water monitor lizards. The purpose of this observation was to prove water monitor lizards as carnivores. Water monitor lizards have pleurodont type canines that stick to the side of the jaw. In the water monitor lizard intestine, no caecum is found. Ratio length intestinus to SVL is less than 1. Endoparasites, in the form of nematode and cestoda worms, are found only in the stomach of water monitor lizards. Based on this observation water monitor lizards are classified as carnivores

    Aspek Reproduksi Ikan Gabus Cina (Channa Lucius C.V) Di Tasik Bungsu, Perairan Sungai Bukit Batu, Riau
    (2018-08-21) Setyawatiningsih, Sri Catur; Yusfiati, Yusfiati
    Sungai Bukit Batu terdapat dalam Cagar Biosfer Giam Siak Kecil-Bukit Batu (GSK–BB). Cagar Biosfer GSK-BB terletak di tiga kabupaten masing-masing Bengkalis, Siak dan Kota Dumai (Pemerintah Kota Dumai 2009). Perairan sungai Bukit Batu tergolong ekosistem floodplain river atau sungai rawa banjiran. Ekosistem sungai rawa banjiran merupakan ekosistem yang kompleks terdiri dari sungai, anak sungai, dan danau banjiran yang masing-masing mempunyai fungsi tertentu untuk kelangsungan hidup ikan di habitat tersebut (Welcomme 1979). Salah satu ikan yang terdapat di sana adalah ikan gabus Cina (Channa lucius) (Anonim 2007). C. lucius merupakan salah satu jenis ikan liar yang secara alami ditemukan di tasik Bungsu, perairan sungai Bukit Batu Riau, yang bernilai ekonomis karena dapat dikonsumsi dan dijadikan ikan hias. Pada saat ini kuantitas C. lucius telah menjadi tersedia di pasar lokal, dimana stoknya berasal dari alam. Jika kondisi tersebut dibiarkan dapat berakibat mengancam kelestarian ikan tersebut. Disamping itu, hingga saat ini belum ada informasi tentang aspek reproduksi C. lucius di sana. Oleh karena itu perlu dilakukan penelitan tentang aspek reproduksi C. lucius di tasik Bungsu, perairan sungai Bukit Batu, Riau. berdasarkan perbandingan seksualitas, tingkat kematangan gonad, indeks kematangan gonad, fekunditas dan sebaran diameter telur
