Microplastic pollution poses a threat to the life of aquatic organisms. Accumulated microplastics in the digestive tracts of these organisms can hinder growth, affect reproduction, and cause internal organ damage. This research aims to determine the abundance and forms of microplastics in water, sediment, gills, and digestive tracts of Nile Tilapia (Oreochromis niloticus) in Situ Rawa Besar, Depok. Water and sediment samples were collected from three sampling stations in the lake. Five Nile Tilapia samples were taken from each station. Gill and digestive tract samples were digested using 65% nitric acid (HNO3) solution. Twenty liters of water were collected and filtered using a plankton net. Sediment samples were dried in an oven, with 25 grams used for analysis. A saturated NaCl solution was employed to separate microplastics from impurities. One milliliter of the sample was dropped onto a Sedgewick Rafter Chamber, then observed and counted based on microplastic forms under a microscope. The research results in July 2022 indicated that microplastic abundance ranged from 15.00 to 23.33 particles L-1 in water, 20,330.00 to 45,330.00 particles kg-1 in sediment, 182.67 to 593.33 particles ind-1 in gills, and 596.00 to 701.33 particles ind-1 in the digestive tract. These abundances were lower than those in September 2023, ranging from 24.33 to 34.67 particles L-1 in water, 31,000.00 to 65,670.00 particles kg-1 in sediment, 317.33 to 744.00 particles ind-1 in gills, and 844.00 to 1,120.00 particles ind-1 in the digestive tract. The most dominant form of microplastics was fragments in water, Nile Tilapia, and sediment. This research indicates an increase in the quantity of microplastics in Situ Rawa Besar over time, supported by factors such as population growth, increased plastic waste, anthropogenic activities, and rainfall."

Penelitian ini bertujuan untuk menentukan kandungan logam berat seng (Zn) dan timbal (Pb) pada sedimen dan ikan mujair (Oreochromis mossambicus), serta mengetahui nilai Bioconcentration Factor (BCF) logam berat seng dan timbal pada ikan mujair di tambak Blanakan, Subang, Jawa Barat. Pengambilan sampel dilakukan menggunakan metode purposive sampling pada tiga stasiun dengan titik inlet, midlet, dan outlet. Sampel sedimen diambil sebanyak 500 gram pada setiap titik dari ketiga stasiun, sedangkan ikan mujair diambil sebanyak 5 individu dari setiap stasiun. Preparasi sampel dilakukan dengan cara sampel sedimen dikeringkan ke dalam oven, sedangkan ikan mujair dibedah untuk didapatkan sampel daging. Analisis kandungan logam berat seng menggunakan metode Atomic Absorption Spectrophotometry (AAS), sedangkan logam timbal menggunakan metode Inductively Coupled Plasma (ICP). Berdasarkan hasil analisis, kandungan logam berat seng pada sedimen berkisar 15,21 – 43,94 ppm, sedangkan logam timbal berkisar 5,04 – 7,88 ppm. Kandungan logam berat seng pada ikan mujair berkisar 3,33 – 8,21 ppm, sedangkan logam timbal tidak terdeteksi. Nilai BCF logam seng pada ikan mujair berkisar 0,132 – 0,311 (deconcentrator). Nilai BCF logam timbal pada ikan mujair tidak dapat ditentukan.

The Blanakan ponds area, Subang, West Java, is a place for aquaculture where various anthropogenic activities have influenced the vicinity. Mozambique tilapia is one of the aquaculture commodities at Blanakan ponds, which is widely consumed and traded. This study aims to determine the content of heavy metals zinc (Zn) and lead (Pb) in sediments and mozambique tilapia (Oreochromis mossambicus), and to determine the value of the Bioconcentration Factor (BCF) of heavy metals zinc and lead in mozambique tilapia at Blanakan ponds, Subang, West Java. Sampling was carried out using the purposive sampling method at three stations with inlet, midlet, and outlet points. Sediment samples were taken as much as 500 grams at each point from the three stations, while 5 individuals of mozambique tilapia were taken from each station. Sample preparation was carried out by drying the sediment samples in an oven, while the mozambique tilapia were dissected to obtain meat samples. Analysis of the heavy metal content of zinc used the Atomic Absorption Spectrophotometry (AAS) method, while lead metal used the Inductively Coupled Plasma (ICP) method. Based on the analysis results, the heavy metal content of zinc in the sediment ranged from 15,21 – 43,94 ppm, while lead metal ranged from 5,04 – 7,88 ppm. The heavy metal content of zinc in mozambique tilapia ranged from 3,33 – 8,21 ppm, while lead metal was not detected. The BCF value of zinc metal in mozambique tilapia ranged from 0,132 – 0,311 (deconcentrator). The BCF value of lead metal in mozambique tilapia cannot be determined."

"Tambak Blanakan merupakan kawasan budidaya perikanan yang berada di daerah pesisir Kabupaten Subang, Jawa Barat. Kawasan di sekitar tambak merupakan tempat padat aktivitas yang berpotensi menyebabkan kontaminasi logam berat masuk ke dalam perairan tambak. Logam berat yang masuk dapat memengaruhi organisme akuatik seperti ikan. Ikan mujair (Oreochromis mossambicus) merupakan salah satu ikan budidaya yang dikonsumsi oleh manusia. Penelitian ini bertujuan untuk menentukan kandungan logam berat kadmium (Cd) dan tembaga (Cu) pada sedimen dan ikan mujair Oreochromis mossambicus, serta menentukan nilai Bioconcentration Factor (BCF) logam Cd dan Cu pada ikan mujair di tambak Blanakan, Kabupaten Subang, Jawa Barat. Penentuan lokasi pengambilan sampel dengan metode purposive sampling pada tiga stasiun dengan tiga titik, yaitu inlet, midlet, dan outlet. Sampel sedimen diambil sebanyak 500 g pada setiap titik dari ketiga stasiun dan sampel ikan mujair diambil sebanyak 5 ekor pada tiap stasiun dengan berat berkisar antara 50–150 g. Sampel sedimen dikeringkan sebanyak 200 g dan sampel bagian daging ikan mujair diambil sebanyak 100 g/stasiun sebelum dianalisis kandungan logam berat. Logam berat kadmium pada sedimen dan ikan mujair dianalisis dengan Atomic Absorption Spectrophotometry (AAS) dan Inductively Coupled Plasma (ICP), sedangkan logam berat tembaga pada kedua sampel dianalisis dengan AAS. Hasil analisis kandungan logam tembaga pada sedimen rata-rata berkisar antara 5,54–8,31 ppm, sedangkan analisis logam tembaga pada ikan mujair rata-rata sebesar 2,05 ppm. Hasil analisis kandungan logam kadmium baik pada sedimen maupun ikan mujair tidak terdeteksi (not detected). Nilai BCF logam tembaga adalah BCF<1, menunjukkan bahwa ikan mujair di tambak Blanakan termasuk dalam kategori dekonsentrator.

Blanakan ponds is an aquaculture area located in the coastal area of Subang Regency, West Java. The area around the pond is a dense place of activity that has the potential to cause heavy metal contamination to enter the pond waters. Heavy metals that enter can affect aquatic organisms such as fish. Mozambique tilapia (Oreochromis mossambicus) is one of the cultivated fish that is consumed by humans. This study aims to determine the content of heavy metals cadmium (Cd) and copper (Cu) in sediment and Mozambique tilapia Oreochromis mossambicus, as well as determine the value of the Bioconcentration Factor (BCF) of Cd and Cu metals in Mozambique tilapia in Blanakan ponds, Subang Regency, West Java. Determination of the sampling location by purposive sampling method at three stations with three points, namely inlet, midlet, and outlet. Sediment samples were taken as much as 500 g at each point from the three stations and samples of Mozambique tilapia were taken as many as 5 fish at each station with a weight ranging from 50–150 g. Sediment samples were dried as much as 200 g and samples of Mozambique tilapia meat were taken as much as 100 g/station before being analyzed for heavy metal content. Cadmium heavy metal in sediment and Mozambique tilapia was analyzed by Atomic Absorption Spectrophotometry (AAS) and Inductively Coupled Plasma (ICP), while copper heavy metal in both samples was analyzed by AAS. The results of the analysis of copper metal content in sediments averaged between 5.54–8.31 ppm, while the analysis of copper metal in Mozambique tilapia averaged 2.05 ppm. The results of the analysis of the metal content of cadmium in both sediment and Mozambique tilapia were not detected. The BCF value of the copper metal is BCF <1, indicating that the Mozambique tilapia in the Blanakan ponds are included in the deconcentrator category."
