Abstract

Heavy metal pollution can disturb aquatic ecosystems and indicator of water quality. This study aims to determine the concentration of heavy metals (Pb, Cu, Cd, Zn) in water and sediments. This study was conducted in the waters of Serangan, South Denpasar District, Bali in June-August 2019. The research with each location taking 8 points of water and sediment sampling and measuring the quality of its waters. Water samples taken at the surface of the water as much as 330 ml and sediment samples taken as much as 500 grams. The method used is wet ashing preparation and analyzed by means of AAS (Atomic Absorbsion Spektrophotometri). The results of the average analysis of heavy metal concentrations in water are Pb 0 mg / L, Cd 0.438 mg / L, Cu 0 mg./L, and Zn 0.284 mg / L. The results of the analysis are compared with the standard quality value of sea water that the heavy metals Cd and Zn have exceeded the threshold. While the average concentration of heavy metals in sediments are Pb 17.444 mg / kg, Cd 18.093 mg / kg, Cu 113.981 mg / kg, and Zn 53.505 mg / kg. The concentration of Cd and Cu heavy metals exceeds the limits set by the ANZECC / ARMCANZ quality guidelines and the Canadian Council of Ministers of the Environment.

Abstract

The downstream area of Unda River Watershed located in Klungkung Regency has experienced succession due to the eruption of Mount Agung in 1963. The ecosystem in the downstream area of the Unda River also experienced anthropogenic succession due to human activities which affected the plant species that composing the vegetation. This study aims to observe the floristic composition of vegetation in the downstream area of the Unda River. The research was conducted by exploration method in three types of ecosystems: lowland forest, marshes, and beaches. The results show the floristic composition in the downstream of Unda River composed by 163 plant species, classified in 48 families and 128 genera. The major growth form is small herb (47 species), grass (35 species), and tree (31 species). Fabaceae is the plant family with the most abundant species, followed by Poaceae and Cyperaceae. Based on the research zones, the lowland forest has the highest number of plant species (120 species), while the beach zone has the lowest (82 species). The ecosystem stability in the downstream area of Unda River can be disturbed by the existence of invasive species, such as Eichhornia crassipes, Chromolaena odorata, Lantana camara, Ipomoea carnea, Vachellia farnesiana, and Typha angustifolia.

Abstract

Kerang merupakan salah satu sumberdaya laut di Pulau Serangan yang telah lama dimanfaatkan oleh masyarakat sebagai sumber bahan pangan bergizi dan bernilai ekonomis. Penelitian ini bertujuan untuk menganalisis kandungan logam berat timbal (Pb) pada kerang yang dimanfaatkan oleh masyarakat di kawasan perairan Serangan. Sampel kerang diperoleh dari hasil tangkapan masyarakat di tiga lokasi dan tempat pengumpul kerang. Metode yang digunakan adalah preparasi pengabuan basah dan dianalisis dengan alat ICPE (Inductedvely coupled plasma emission). Hasil penelitian menunjukkan kandungan logam berat timbal (Pb) pada kerang bernilai ekonomi (Marcia opima, Marcia hiantina, Perna sp.) yang ditangkap oleh nelayan melebihi ambang batas BPOM (2,093 - 2,571 mg/kg). Namun proses pendedahan dengan perendaman 24 jam menurunkan kandungan timbal (Pb) di bawah ambang batas (0,387 - 0,971 mg/kg).
