Abstract

Zooplankton merupakan organisme mikroskopik yang hidupnya mengapung dan sangat bergantung pada arus air. Kehadiran zooplankton dengan kelimpahan yang tinggi dapat digunakan sebagai petunjuk kondisi perairan di suatu wilayah tersebut berada dalam kondisi yang baik ataupun buruk. Penelitian ini bertujuan untuk mengetahui komposisi, kelimpahan, keanekaragaman zooplankton dan hubungan kelimpahan dan keanekaragaman zooplankton dengan faktor lingkungan perairan di Pulau Belitung. Pengambilan data dilakukan secara purposive sampling pada 12 stasiun penelitian. Data dianalisis secara deskriptif dan statistik dengan melakukan perhitungan kelimpahan dan indeks biologi serta uji multivariat Canonical Correspondence Analysis (CCA) dengan menggunakan software PAST statistical. Hasil penelitian menunjukkan terdapat 25 jenis zooplankton teridentifikasi. Komposisi dan kelimpahan zooplankton didominasi oleh jenis zooplankton Calanus sp., Candacia sp., Centropages sp., Acartia sp., dan Eucalanus sp. dengan kelimpahan tertinggi dimiliki oleh Calanus sp. dan kelimpahan terendah pada Scolecithricella sp. Indeks keanekaragaman menunjukkan kategori sedang, indeks keseragaman menunjukkan kategori tinggi dan dominansi rendah. Hubungan antara keanekaragaman zooplankton dengan faktor lingkungan perairan menunjukkan hubungan yang relatif lemah. Secara keseluruhan parameter perairan seperti arus, suhu, salinitas, pH, dan turbiditas berkolerasi dengan kelimpahan zooplankton yang memainkan peran penting dalam menentukan distribusi spesies zooplankton(*****)Zooplankton are microscopic organisms that drift with water currents and rely heavily on these currents for their movement and survival. The presence of zooplankton in high abundance can serve as an indicator of water quality, reflecting whether the conditions of a given aquatic environment are healthy or degraded. This study aimed to analyze the composition, abundance, and diversity of zooplankton, as well as their relationship with aquatic environmental factors on Belitung Island. This study uses descriptive statistical analysis with a survey method. Data were collected through purposive sampling at 12 research stations and analyzed using descriptive and statistical methods, including the calculation of abundance and biological indices, along with multivariate Canonical Correspondence Analysis (CCA) performed through PAST statistical software. The findings identified 25 zooplankton species in the study area. The composition and abundance were dominated by Calanus sp., Candacia sp., Centropages sp., Acartia sp., and Eucalanus sp., with Calanus sp. exhibiting the highest abundance, while Scolecithricella sp. showed the lowest abundance. The diversity index indicated a moderate category, the uniformity index reflected a high category, and the dominance index was low. The relationship between zooplankton diversity and environmental factors in the waters showed a relatively weak correlation. Overall, water parameters such as current, temperature, salinity, pH, and turbidity were correlated with zooplankton abundance, which plays an important role in determining the distribution of zooplankton species.
