Analisis Beban Pencemaran Tambak Udang di Sekitar Sungai Kembung Kecamatan Bantan Bengkalis

Abstract

Research on pollution load of shrimp ponds around Sungai Kembung in Bengkalis Island Riau Province cultivate shrimp with intensive cultivation technology. Feeding that is not appropriate for size can contribute nitrate and phosphate levels to nature that can trigger eutrophication. The purpose of this research is to analyze the pollution load BOD5, DO, NO3 - dan PO4-3 at Sungai Kembung. The results showed that pollutant concentrations in the River Kembung had crossed the threshold according to KepMen LH No 51/Men-KLH/2004 which is destined for marine biota. The pollution load BOD5 shows that Statiun 2 is the highest station receiving pollution loads equal to 16.094 tons/month. Nitrate pollution load on the Station 2 is the highest station to receive pollution load is equal to 39 tons/month. The pollution load of phosphate indicates that the Station 2 is the highest station to receive pollution load that is equal to 38 tons/month. The pollution load of DO indicates that the smallest contamination load (the most polluted) is on the Station 1 equal to 278 tons/month.

The Performance of Microalgae (Nannochloropsis sp., Tetraselmis sp. and Dunaliella sp.) on White Shrimp (Litopenaeus vannamei) Wastewater Cultivation Media

“…Such organic material rot will accumulate at the base of the water and affect the quality of the aquatic environment so that the water change is needed in the pond (Chen et al, 2018). The process of changing the water in the pond is done by disposal through the top of the pond, the result is also called the wastewater shrimp (Harianja et al, 2018). Water change activities in the pond impact the environment and ecosystem surrounding the form of organic material content, so that management is needed to keep the cultivation activities ongoing and sustainable (Saiya and Katoppo, 2015).…”

Analisis Dampak Tambak Udang pada Ekosistem Laut di Kebumen

“…Kandungan yang terdapat pada limbah berupa zat organik yang mempunyai karakteristik mudah menguap dan membutuhkan waktu yang cukup lama untuk dapat diuraikan. Limbah tersebut berpengaruh pada kehidupan makhluk hidup yang ada di lingkungan sekitar (Harianja et al, 2018). Sisa pakan yang tidak dimanfaatkan oleh udang juga menjadi penyumbang bahan pencemar.…”

The Effect of Vaname Shrimp Pond Waste Disposal (Litopenaeus van-namei) on The Environment and Environmental Law Perspective: a Literatur Review

“…Meningkatnya usaha tambak udang di beberapa wilayah diakibatkan tingginya minat masyarakat untuk mengkonsumsi udang. Hal yang menjadi permasalahan ialah limbah dari sisa pakan dan kotoran udang yang dibuang langsung ke perairan tanpa dilakukan pengolahan terlebih dahulu (Harianja et al, 2018). Permasalahan ini dipicu dengan produksi udang yang tinggi sehingga pakan yang digunakan tentu juga banyak.…”
