Abstract
Tumbuhan air memiliki banyak peranan seperti sumber makanan bagi organisme akuatik, penahan arus, penangkap sedimen menganalisis hubungan kelimpahan biofilm pada tumbuhan air dengan parameter fisika-kimia perairan. Penelitian dilakukan dengan metode survei. Lokasi pada penelitian ini dibagi menjadi 4 yakni lokasi 1 dengan vegatasi tinggi seluas 23,2 m2, lokasi 2 dengan vegetasi sedang yakni seluas 13,4 m2, lokasi 3 dengan vegetasi jarang seluas 6,95 m2 hingga lokasi 4 dengan vegetasi rendah seluas 4,72 m2. Tumbuhan air diambil dari transek 1 m x 1 m pada setiap lokasi dan diambil sebanyak 3 sampel dari masing-masing jenis, kemudian didokumentasikan. Pengambilan sampel biofilm dilakukan dengan menimbang 50 gr dari setiap jenis tumbuhan air pada bagian yang masih terpengaruh oleh perairan baik dari akar batang dan daun. Tumbuhan air yang telah ditimbang, di masukkan dalam wadah 200 ml kemudian di tambahkan aquadest serta diberi lugol 1% dan formalin 4%. Parameter fisika dan kimia perairan yang diukur meliputi suhu, kecerahan, kecepatan arus, pH, oksigen terlarut, CO2, nitrat dan ortofosfat. Jenis-jenis tumbuhan air yang ditemukan yaitu eceng gondok, melati air, kiapu, kiambang, kumbuh, kremah air, perisai air dan rumput lampuyangan. Kelimpahan tumbuhan air Rawa Klampok pada 4 lokasi berkisar antara 2–22,33 ind/m2. Biofilm yang ditemukan dari substrat tumbuhan air sebanyak 82 jenis terdiri dari 4 divisi dan 6 filum, 3 divisi tersebut yakni Ochrophyta, Cyanophyta, Charophyta dan Chlorophyta, sedangkan untuk filum terbagi menjadi 6 yakni Amoebozoa, Arthropoda, Ciliophora, Euglenozoa, Protozoa dan Rotifera. Kelimpahan relatif biofilm berkisar antara 0,02–19,10% dengan kelimpahan tertinggi yakni kelompok tumbuhan divisi Ochrophyta (Melosira sp.) dan terendah adalah kelompok hewan filum Ciliata yaitu Vorticella sp. Indeks keanekaragaman biofilm berkisar antara 2.59–3.20 tergolong sedang hingga tinggi. Komunitas biofilm pada tumbuhan air dalam penelitian ini relatif sama (kesamaan 84%) kecuali biofilm pada tanaman kumbuh hanya mencapai 16% karena kumbuh hidup di tepi rawa tidak semua bagian tanamannya terendam perairan. Kesamaan biofilm di tanaman Kremah air hanya mencapai 33% karena tumbuh di habitat yang sama dengan kumbuh. Biofilm divisi Cyanophyta, Charophyta, Chlorophyta dan Ochrophyta sebagian besar berhubungan kuat dengan semua parameter kualitas air terutama CO2, kecerahan, nitrat dan ortofosfat kemudian filum Protozoa, Ciliophora, dan Amoebozoa memiliki kaitan kuat dengan suhu, pH, kecepatan arus dan DO. Filum Rotifera, Euglenozoa dan Arthropoda berkaitan erat dengan parameter DO, suhu, pH dan kecepatan arus. Berdasarkan penelitian yang sudah dilakukan maka saran yang dapat disampaikan yakni perlu adanya penyuluhan dan himbauan kepada masyarakat serta pelaku wisata supaya lebih bijak dalam memanfaatkan Rawa Klampok untuk aktivitas sehari-hari dan bagi pemerintah diharapan adanya kebijakan terkait pengelolaan lingkungan seperti adanya pengolahan sampah dan penggunaan pupuk alami di sekitar Rawa Klampok.
English Abstract
Aquatic plants have many roles, such as a food source for aquatic organisms, current arrestors, sediment catchers and as a substrate for attachment to epiphytic algae. The purpose of this study was to obtain aquatic plants species, analyze the community structure of periphyton found in these aquatic plants and analyze the relationship between the abundance of periphyton in aquatic plants and the physical and chemical parameters of the waters. The location in this study divided into 4 stations, location 1 with high vegetation covering an area of 23.2 m2, location 2 with medium vegetation covering an area of 13.4 m2, location 3 with sparse vegetation covering an area of 6.95 m2 to location 4 with low vegetation covering an area of 4.72 m2. Aquatic plants were taken from a 1m X 1m transect at each station. Aquatic plants were taken as many as 3 units of each type and then documented. Periphyton sampling was carried out by weighing 50 grams of each type of aquatic plant in the part that is still affected by water, both from the roots, stems and leaves. Furthermore, the aquatic plants that have been weighed, put in a 200 ml container then added distilled water and given 1% lugol and 4% formalin. Physical and chemical parameters of the waters measured included temperature, brightness, current velocity, pH, dissolved oxygen, CO2, nitrate and orthophosphate. The types of aquatic plants found were water hyacinth, water jasmine, water lettuce, water spangles, river bulrush, alligator weed, water shield and torpedo grass. The abundance of Rawa Klampok aquatic plants at 4 locations ranged from 2–22.33 ind/m2. There were 82 types of biofilms found from aquatic plant substrates consisting of 4 divisions and 6 phyla, the 3 divisions such as Ochrophyta, Cyanophyta, Charophyta and Chlorophyta, while the phyla were divided into 6 such as Amoebozoa, Arthropoda, Ciliophora, Euglenozoa, Protozoa and Rotifera. The relative abundance of biofilms ranged from 0.02–19.10% with the highest abundance being the plant group of the Ochrophyta division (Melosira sp.) and the lowest being the animal group of the ciliate phylum, Vorticella sp. The biofilm diversity index ranges from 2.59–3.20 which is classified as moderate to high. The biofilm community on aquatic plants in this study was relatively the same (84% similarity), except for the biofilm on river bulrush which only reached 16% because it lives on the edge of a swamp, not all parts of the plant are submerged in water. The biofilm similarity in the water alligator weed only reached 33% because it grows in the same habitat as the river bulrush. Most of the Cyanophyta, Charophyta, Chlorophyta and Ochrophyta division biofilms have a strong relationship with all water quality parameters, especially CO2, brightness, nitrate and orthophosphate then the Protozoa, Ciliophora and Amoebozoa phyla have a strong relationship with temperature, pH, current velocity and DO. Phylum Rotifera, Euglenozoa and Arthropoda are closely related to parameters of DO, temperature, pH and current velocity. Based on the research that has been done, the suggestions that can be conveyed are that there is a need for counseling and appeals to the public and tourism actors so that they are wiser in utilizing Rawa Klampok for their daily activities and for the government it is hoped that there will be policies related to environmental management such as waste management and the use of natural fertilizers around Rawa Klampok.
