Abstract

Study in order to know feeding behavior of Asian Barb (Barbodes schwanenfeldii, Blkr) in Kampar river, Riau Province, was carried out in July and October 2003. Study was conducted by using field survey and Laboratory Analysis. Two sampling sites in Kampar River. Desa Pulau located at the upper part of Kampar river and Desa Danau Bingkuang located at the middle part of Kampar river were chosen based on stratification method. The research showed us, that the sequence of the feeding habit of the Asian Barb in Kampar river, in July and October 2013. Concist of fitoplankton the main food with the preponderance index value of 41,57%-48,37% The complementary food which consisf plants with prefonderance index value of 31,75%-37,99%, unidentified food with prefonderance index value of 2,09%-3,17%: the zooplankton with prefonderance index value of 0,49%-1,23% and nematode with prefonderance index value of 0,14%-0,65%. Based on the sequence of the feeding habit of the Asian Barb and tha correlation between the length of the body with ratio the length of the intestine and the length of the body Asian Barb, Asian Barb in Kampar river categorized as herbivorous fish. The environmental condition in the upper and the middle of Kampar river this can still support the growth of Asian Barb.  Keywords: Asian Barb (Barbodes schwanenfeldii, Blkr), Kampar river, Indeks of Profenderance Value

Abstract

Acraea terpsicore L. (Lepidoptera : Nymphalidae) merupakan salah satu jenis kupu-kupu yang memiliki sebaran terbanyak di Universitas Sriwijaya Indralaya, dan larvanya ditemukan dapat memakan tanaman inang Piriqueta racemosa (Passifloraceae). Tujuan penelitian ini untuk mengetahui lama hidup dan perilaku makan pada A. terpsicore pada tanaman P. racemosa. Penelitian ini dilaksanakan pada bulan Januari sampai dengan bulan Februari 2020 di Rumah Kupu-Kupu Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam Universitas Sriwijaya Indralaya, Sumatera Selatan. Penelitian lama hidup dan perilaku makan stadia pradewasa (larva) A. terpsicore pada tanaman inang P. racemosa dilakukan menggunakan metode deskriptif dan pengamatan perilaku makan menggunakan metode visual recording yang meliputi: deskripsi morfologi setiap stadia, lama waktu perkembangan setiap stadia, dan perilaku makan larva. Hasil penelitian lama hidup kupu-kupu A. terpsicore dari telur sampai ke imago berlangsung selama 34 – 44 hari dengan rata-rata 38,12 ± 2,34 hari, dengan angka kelulusan hidup sebesar 40%. Perilaku makan larva A. terpsicore pada tanaman inang P. racemosa sangat bervariasi antar

Abstract

The Mangrove Forest Nature Reserve East Coast (CAHBPT) in Jambi Province has functions, one of which is to improve water quality by absorbing dangerous heavy metals such as Pb and Cu which come from various human activities around the waters. This absorption can be done by using hyperaccumulator plants such as Rhizophora apiculata Blume. This study aims to determine the potential and mechanism of R. apiculata in the phytoremediation of heavy metals Pb and Cu in the CAHBPT area, Alang-Alang Village, Tanjung Jabung Timur Regency, Jambi Province. Sampling was carried out using the purposive sampling method at three stations. The calculation of the Bioconcentration Factor (BCF) aims to determine the potential of R. apiculata in phytoremediation Pb and Cu metals, as well as the calculation of the Translocation Factor (TF) to determine the phytoremediation mechanism of R. apiculata. The results of this research found that the accumulation of Pb and Cu metals in sediments ranged from 11.04-12.36 mg/kg and 7.93-9.08 mg/kg. The accumulation of Pb and Cu metals in the roots of R. apiculata ranges from 2.34-2.65 mg/kg and 1.56-2.93 mg/kg. The accumulation of Pb and Cu metals in the shoots of R. apiculata ranged from 2.77-3.16 mg/kg and 0.61-1.05 mg/kg. The phytoremediation potential of R. apiculata at the research site is included in the excluder category or plants still limit the accumulation of heavy metals entering the body (BCF<1). R. apiculata at the research site translocated Pb metal using a phytoextraction mechanism (TF>1) and Cu metal using a phytostabilization mechanism (TF<1).
