Abstract

Budidaya udang secara intensif telah menimbulkan beberapa permasalahan lingkungan salah satunya menimbulkan pencemaran. Bahan pencemar tersebut berasal dari biotik dan abiotik. Bahan pencemar biotik seperti parasit, bakteri dan virus, sedangkan bahan pencemar abiotik seperti nitrat dan fosfat. Tata letak tambak di Kecamatan Pontang tidak teratur dan pengelolaan airnya tidak sesuai standar budidaya ikan yang baik/biosecurity. Hal ini berpotensi bahan pencemar akan menyebar dari satu tambak ke tambak lainnya. Kondisi tersebut berkaitan dengan potensi bakteri, tingkat saprobitas dan status lingkungan di tambak tersebut. Tujuan peneltian ini adalah untuk menganalisa potensi bakteri, tingkat saprobitas dan status lingkungan. Pengambilan sampel dengan metode purposive sampling. Sampel diambil pada 10 stasiun pada tambak udang intensif, tambak tradisional bandeng, saluran air dan sungai. Hasil penelitian menunjukkan bahwa kelimpahan bakteri heterotrof dibawah 106 dan bakteri patogen (Vibrio) dibawah 104 CFU/ml. Jenis bakteri yang ditemukan adalah Vibrio, Pseudomonas, Pasteurella dan Acinotobacter. Tingkat saprobitas menunjukkan perairan tercemar ringan sampai berat. Status lingkungan berdasarkan potensi bakteri, saprobitas dan kualitas air menunjukkan kondisi layak/sesuai untuk usaha perikanan budidaya dengan adanya faktor pembatas yang berpengaruh terhadap produktivitas.

Intensive shrimp farming has caused several environmental problems, one of which is pollution. These pollutants come from biotic and abiotic sources. Examples of biotic contaminants such as parasites, bacteria, and viruses. While abiotic pollutants such as nitrates and phosphates. Irregular layout and water management is are not according to a good aquaculture/biosecurity standards in Pontang Subdistrict, which can spread pollutants. These conditions affect the potential of bacteria, saprobity and environmental status. This research aimed to analyze the potential of bacteria, saprobity level, and environmental status. Sampling by purposive sampling method. Samples were taken at 10 stations in intensive shrimp ponds, traditional milkfish ponds, waterways, and rivers. The results showed that the abundance of heterotrophic bacteria was below 106 CFU/ml and pathogenic bacteria (Vibrio) was below 104 CFU/ml. The types of bacteria found were Vibrio, Pseudomonas, Pasteurella, and Acinetobacter. The level of saprobity indicates lightly to heavily polluted waters. The environmental status based on the potential of bacteria, saprobity and water quality shows the condition is feasible/suitable for aquaculture business with the presence of limiting factors that affect productivity.
