Abstract

Aquatic ecosystems are very important for biodiversity and play a crucial role for the environment as well as for humans. Phytoplankton, the primary producers in this system, significantly contribute to oxygen production and CO2 absorption, making them crucial for global climate regulation. However, climate change marked by rising temperatures and unpredictable weather patterns has negatively impacted the abundance and distribution of phytoplankton, thereby threatening marine biodiversity and the stability of ecosystems. This study focuses on analyzing the impact of climate change on the abundance of phytoplankton in the oceans and identifying strategies to address it, through literature review. The research results indicate a significant decline in phytoplankton abundance, influenced by significant temperature changes from year to year. Effective mitigation strategies, including efforts to reduce greenhouse gases, protect biodiversity, and educate the public, are essential for preserving aquatic ecosystems. This research emphasizes the need for immediate and sustained action to protect marine biodiversity and ensure ecological balance.

Abstract

ABSTRAK Penyakit Acute Hepatopancreatic Necrosis Disease (AHPND) merupakan salah satu ancaman utama dalam budidaya udang yang disebabkan oleh Vibrio parahaemolyticus pembawa plasmid toksin PirAB. Upaya pengendalian konvensional berbasis antibiotik telah memunculkan permasalahan resistensi antimikroba dan kerusakan mikrobiota usus. Artikel ini merupakan tinjauan pustaka yang bertujuan untuk mengevaluasi potensi mikroorganisme, khususnya genus Bacillus, sebagai agen biokontrol alternatif dalam mengendalikan AHPND. Berbagai riset yang dipublikasikan dalam sepuluh tahun terakhir dianalisis secara kritis untuk menilai efektivitas, mekanisme kerja, dan tantangan aplikatif probiotik mikroorganisme terhadap AHPND. Hasil analisis menunjukkan bahwa beberapa strain Bacillus, seperti B. subtilis, B. licheniformis, dan B. velezensis, mampu menekan infeksi AHPND secara signifikan melalui produksi senyawa antibakteri dan stimulasi imun udang. Artikel ini juga mengungkap adanya ketidakkonsistenan metodologis dalam pengujian efektivitas probiotik dan pentingnya harmonisasi eksperimen untuk pengembangan probiotik skala industri. Kajian ini memberikan perspektif ilmiah berbasis bukti mengenai peran mikroorganisme dalam akuakultur berkelanjutan bebas antibiotik. Kata kunci: AHPND, Bacillus, biokontrol, probiotik, Vibrio parahaemolyticus
