      Abstract
      MIRANDIKA IDRIS. Identifikasi Keanekaragaman Zooplankton di Ekosistem Danau Laut dan Perairan Sekitar Distrik Misool, Kabupaten Raja Ampat. Dibimbing oleh ENDANG SUNARWATI SRIMARIANA dan DEA FAUZIA LESTARI. Danau laut adalah suatu badan air yang terisolasi oleh daratan dan memiliki konektivitas dengan laut melalui jalur bawah tanah. Penelitian zooplankton telah banyak dilakukan di Perairan Indonesia tetapi belum banyak dilakukan di ekosistem danau laut. Penelitian ini penting dilakukan mengingat peran zooplankton sebagai bioindikator suatu lingkungan. Penelitian ini bertujuan mengidentifikasi spesies dan menganalisis struktur komunitas zooplankton pada ekosistem Danau laut Misool, Raja Ampat, Papua Barat Daya. Pengambilan sampel dilakukan di 7 ekosistem danau laut pada 2-10 Mei 2023. Dilakukan dengan metode horizontal towing. Berdasarkan hasil penelitian ditemukan 23 genera zooplankton. Nauplius merupakan organisme paling banyak ditemukan dengan presentase sebesar 54.3% dari keseluruhan stasiun pengamatan. Struktur komunitas zooplankton pada lokasi kajian antara lain, indeks keanekaragaman berkisar antara 0.52-2.11, indeks keseragaman berkisar antara 0.48-0.97, dan indeks dominansi berkisar antara 0.16- 0.74 dengan adanya dominasi tingkat sedang oleh Nauplius pada lokasi dalam Danau Tipkapas. Kata kunci: zooplankton, danau laut, Misool Raja Ampat, Nauplius
       
      MIRANDIKA IDRIS Zooplankton Diversity Identification in the Marine Lake Ecosystem and Surrounding Waters of Misool District, Raja Ampat Regency. Supervised by ENDANG SUNARWATI SRIMARIANA and DEA FAUZIA LESTARI. A marine lake is a landlocked body of water with a subterranean connection to the ocean.. Many zooplankton studies have been conducted in Indonesian waters but not many have been conducted in the marine lake ecosystem. This research is important considering the role of zooplankton as bioindicators of an environment. This study aimed to identify species and analyze the community structure of zooplankton in the marine lake ecosystem of Misool, Raja Ampat, Southwest Papua. Data were collected in 7 marine lake ecosystems on May 2-10, 2023. Horizontal towing method was used. Based on the results of the study, 23 genera of zooplankton were found. Nauplius, Oithona, and Acartia were the most common organisms found with a percentage of 54.3%. The zooplankton community structure in the study area showed diversity indices ranging from 0.52 to 2.11, evenness indices ranging from 0.48 to 0.97, and dominance indices ranging from 0.16 to 0.74, with moderate dominance by Nauplius observed in the inner area of Tipkapas Lake Keywords: zooplankton, marine lake, Misool Raja Ampat, Nauplius
