Abstract

Keberadaan fitoplankton diduga berdampak besar terhadap keberhasilan budidaya lobster terutama di fase pertumbuhan benih bening (puerulus) menjadi juvenil. Lobster pasir (Panulirus homarus) merupakan salah satu spesies spiny lobster yang paling banyak dibudidayakan di Indonesia khususnya di Teluk Ekas, Lombok.  Tujuan penelitian ini adalah untuk mendata jenis, kelimpahan, indeks keanekaragaman (H’), dan  spesies fitoplankton yang potensial sebagai harmful algal blooms (HABs), pada kedalaman penempatan wadah pemeliharaan puerulus lobster di Teluk Ekas pada fase bulan yang berbeda. Sampel fitoplankton diperoleh dari tiga kedalaman penempatan puerulus (0,5 m, 1 m, 1,5 m), ketika fase bulan gelap dan terang pada bulan Juni-Juli 2021. Hasil penelitian menunjukkan tercatat total 53 jenis fitoplankton yang terbagi ke dalam lima kelas yakni Bacillariophyceae (13), Coscinodiscophyceae (10),  Cyanophyceae (1), Dinophyceae (9), dan Mediophyceae (20). Tujuh genus fitoplankton tergolong dalam harmful species (Chaetoceros sp., Dinophysis sp., Nitzschia sp., Skeletonema sp. Trichodesmium sp., Tripos sp. dan Protoperidinium sp.). Fase bulan gelap memiliki kelimpahan fitoplankton yang lebih tinggi dibandingkan bulan terang pada tiap kedalaman laut pengambilan sampel. Fitoplankton paling berlimpah pada lapisan permukaan air laut dan menurun seiring penambahan kedalaman dengan H’ yang bervariasi dan fluktuatif. Analisis kesamaan memperlihatkan bahwa kedalaman 1 m memiliki persen kesamaan yang tinggi dengan kedalaman 1,5 m.

Abstract

Increased greenhouse gas emissions have led to climate change. Indonesia plans to reduce greenhouse gas emissions by 140 million tons of CO₂-equivalent (CO₂e) by 2030. One strategy for achieving this goal is to conserve mangrove habitats. However, unsustainable activities continue to jeopardize the survival of these mangroves. The purpose of this study was to investigate the community structure and sediment carbon content of mangrove ecosystems in Sembilang National Park. Data was obtained at three stations using 100-m transects extending inland from the seashore or riverbank. The sediment carbon analysis was carried out utilizing the Loss on Ignition (LOI) method. Excoecaria agallocha had the highest Importance Value Index (IVI) at the Sungai Barong station, followed by Rhizophora apiculata in the Sungai Sanjang and Birik stations. The mangrove ecosystems at the study sites were characterized as moderately dense. The investigation revealed that the carbon store in mangrove sediments was 1294.14 t/ha, with an average of 431.38 t/ha. Mangrove ecosystems must be managed and protected to ensure that they continue to provide ecological and economic advantages.

Abstract

The coastal waters of Eretan located in the north of Indramayu Regency are used as fishing grounds by local fishermen. The condition of water input, especially from the surrounding river waters, namely the Cimanuk River, Cipunagara River, and Perawan River, is thought to affect the condition of coastal waters. This study aims to analyze the trophic level based on water quality conditions. Data collection on the quality of the aquatic environment was carried out in three locations with purposive sampling considerations, namely the Cipunagara estuary, the Perawan estuary, and the Cimanuk estuary. Sampling was carried out in two different seasons, namely the dry season and the rainy season. The method used in the analysis is the TRIX Index based on nutrients, phosphate, chlorophyll-α, and DO saturation. Meanwhile, water quality parameters at each location were analyzed using principal component analysis (PCA). The results of the study showed that the main water quality parameters tended to differ in each season. The trophic level at the three locations had values between 4.99 and 8.59, so they had mesotrophic to hypertrophic status. This shows that coastal water conditions need to be managed so that water conditions are more stable.
