Kakap River Estuary plays an essential role in the life organisms, but it is vulnerable to environmental changes and pollution caused by human activities. This study aims to assess the presence of plankton species, their abundance and diversity as aquatic ecological bio-indicators in Kakap River Estuary. Plankton and water samples were taken for three months, with a frequency of one sample per month, viz. in March, April and June 2020 from four sampling stations in Kakap River Estuary, West Kalimantan. A total of 34 species of plankton were observed from all sampling sites, and identified to belong to 18 classes. Chlorophyceae had the highest relative abundance among the phytoplanktons (40.10%), followed by Bacillariophyceae (21.86%) and Cyanophyceae (19.28%). Oscillatoria sp. and Hydrodictyon sp. were the most dominant phytoplankton species. There were 8 classes of zooplankton identified from all sampling stations throughout the research period. Hexanauplia had the highest relative abundance among the zooplanktons (36.56%) followed by Euglenophyceae (24.37%). The plankton diversity index (H ′) values ranged between 2.33 -3.11. The plankton evenness index value ranged from 0.79 to 0.89 which indicates high plankton evenness at all samping stations, and this is supported by a low dominance index value at all stations ranging from 0.06-0.16. Station 1 had high Shannon-Wienner diversity index score, while for station 2, 3, 4, their scores were in the moderate level. Overall. the diversity index of the plankton from all sampling sites indicated that the quality of the water had no pollution to light pollution level.Keywords:PhytoplanktonZooplanktonWater quality

Potensi perikanan budidaya ikan air tawar di desa Sambora, kecamatan Toho, kabupaten Mempawah cukup besar terlebih potensi tersebut didukung dengan adanya Balai Budidaya Ikan Sentral Anjongan yang dapat menopang ketersediaan benih bagi mitra kegiatan PkM ini yaitu pembudidaya ikan air tawar di Desa Sambora. Meskipun potensi budidaya ikan air tawar cukup tinggi, namun ketersediaan pakan belum maksimal dengan harga yang masih cukup tinggi. Terkait dengan permasalahan yang dihadapi kelompok mitra, solusi untuk mengatasi permasalahan tersebut adalah dengan melakukan introduksi pakan ikan alami. Kegiatan introduksi ini mencakup peningkatan pengetahuan dan keterampilan terkait pengetahuan berbagai jenis pakan alami yang dapat digunakan sebagai pakan tambahan. Hasil dari kegiatan ini adalah terjadi peningkatan informasi yang berkaitan dengan penggunaan pakan alami sebagai substituent pakan buatan, sebesar 81,8%. Kegiatan sosialisasi dan praktik yang disampaikan cukup mudah untuk diterima dan diduplikasi oleh peserta. Hal ini terlihat dari hanya sejumlah 18,1% peserta yang masih belum tertarik untuk menduplikasi kegiatan ini, dengan alasan keterbatasan alat dan bahan (terutama indukan Daphnia). Sementara itu, 27,3% akan mencoba menduplikasi kegiatan ini, namun peserta masih belum percaya diri dengan hasil yang akan didapatkan. Sedangkan 54,6% lainnya akan mencoba menduplikasi kegiatan ini, dengan tingkat percaya diri yang tinggi dan tingkat keberhasilan yang akan diperoleh juga tinggi. Hasil kegiatan dipandang cukup penting oleh mitra dalam menopang kegiatan budidaya yang telah berjalan di desa Sambora
