Abstract

Dinoflagellate merupakan salah satu kelas dari fitoplankton dan terbagi menjadi dua kelompok, yaitu dinoflagellate autotroph dan heterotroph.bertujuan untuk menganalisis struktur komunitas fitoplankton khususnya dari kelas dinoflagellata, yaitu dalam hal jumlah jenis, dan kelimpahan dinoflagellata di perairan Tarakan Kelurahan Juata laut Kota Tarakan. Jenis Dinoflagellata yang di temui pada perairan juata ada 7 jenis, yaitu dinoflagellate, yaitu: Ceratium spp., Noctiluca sp., Protoperidinium spp., Prorocentrum spp., Gymnodinium sp., Gonyaulax sp., dan Dinophysis sp. Nilai Indeks keanekaragaman, keseragaman dan dominansi dinoflagellata masing-masing berkisar antara 0.06 - 1.53, keseragaman 0.09 – 0.80  dan dominansi  0,23 - 0,95. Nilai indeks keanekaragaman tertinggi terdapat di Stasiun 3 sebesar 1,63 dan keanekaragaman terendah terdapat di Stasiun 5 sebesar 0,07, nilai indeks keseragaman tertinggi terdapat di Stasiun 3 sebesar 0,90 dan indeks keragaman terendah terdapat di Stasiun 5 sebesar 0,10, sedangkan indeks dominansi tertinggi terdapat di Stasiun 3 sebesar 0,97 dan indeks dominansi terendah terdapat di stasiun 9 sebesar 0,23Parameter kualitas air masih menunjukan nilai optimum dengan suhu berkisar 27-30 0C, kecerahan 53 – 63 cm, salinitas 16 -2 4 ppt dan Ph 7,2 – 7,4. Konsentrasi klorofil a, b dan c optimum pada waktu pagi hingga siang dengan pengambilan sampel pukul 08.00 – 12.00 dengan nilai klorofil a 0,3447 µg.L-1, klorofil b 0,2081 µg.L-1dan klorofil c 0,03

Abstract

Tarakan City is a city that has potential natural resources to be developed. One of the areas in the town of Tarakan is Tanjung Pasir, where the residents live in the coastal area. This study aims to determine the quality of the waters of the dune by using the plankton community structure as a water bioindicator. As a research object, Plankton communities in Tanjung Pasir waters include abundance, diversity index, uniformity index, and dominance index. This study uses a quantitative descriptive method with the research location being carried out at two points, namely Station I in the mangrove area and Station II close to residential areas. Sampling was conducted every two days, 15 times out in the field. The types of phytoplankton found in five classes, namely Bacillariophyceae, Coscinodiscophyceae, Cyanophyceae, Mediophyceae, and Dinophycea lessons and zooplankton from Crustacea class at Station I and Station II. Station I and Station II were from classes. The most abundant types of phytoplankton are found in Bacillariophyceae and Dinophyceae because these two classes dominate all kinds of phytoplankton worldwide. The abundance value of phytoplankton at; Station I was 354 cells/l; at Station II, it was 202 cells/l. The abundance of zooplankton at; Station I was 40 ind/l, and at Station, II was 38 ind/l. The diversity index at the two stations is in the medium category, with the uniformity index being in the high uniformity category and the dominance index at each low. Based on the value of the plankton community structure, Tanjung Pasir waters are classified as lightly polluted. Environmental factors of Tanjung Pasir waters in Tarakan city include the physical and chemical characteristics of Station I and Station II, which are still suitable for the life of aquatic organisms.
