Mikroplastik di perairan berpotensi masuk ke tubuh biota laut seperti ikan melalui sistem rantai makanan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik mikroplastik dan menganalisis hubungan antara ukuran ikan dengan kelimpahan mikroplastik pada saluran pencernaan (usus dan lambung) ikan kembung (Rastrelliger sp.) yang didaratkan di PPS Belawan. Pengumpulan sampel ikan dilakukan pada Bulan April 2022 dengan membeli 30 ekor ikan hasil tangkapan nelayan. Analisis laboratorium diawali dengan mengukur panjang (cm) dan berat (gr) ikan, melakukan pembedahan saluran pencernaan, destruksi bahan organik dan identifikasi mikroplastik menggunakan mikroskop. Destruksi bahan organik dilakukan dengan menambahkan larutan H2O2 30% pada saluran pencernaan yang sebelumnya telah ditimbang berat keringnya dengan perbandingan 1:20, kemudian diinkubasi selama 24 jam. Tiga jenis mikroplastik ditemukan di seluruh sampel saluran pencernaan dengan dominansi jenis film (54 %), diikuti oleh fragmen (33 %) dan fiber (13 %). Diantara jenis mikroplastik, film merupakan jenis mikroplastik yang memiliki kelimpahan tertinggi yaitu 2,30±1,30 partikel/gr. Penelitian ini menemukan bahwa ukuran ikan memiliki hubungan yang rendah dengan kelimpahan mikroplastik pada saluran pencernaan ikan. Hal ini dapat dikaitkan dengan kebiasaan makan ikan, makanan ikan, ukuran mulut dan tingkat pencemaran perairan yang berbeda. Microplastic in the waters has the potential to enter the bodies of marine biota such as fish through the food chain system, either directly or indirectly. This study aims to identify the characteristics of microplastics and to analyse the relationship between fish size and the abundance of microplastics in the digestive tract of mackerel (Rastrelliger sp.) landed at Belawan Ocean Fishery Port. The collection of fish samples was carried out in April 2022 by purchasing 30 fish caught by fishermen. Laboratory analysis begins with measuring the length (cm) and weight (g) of the fish, performing digestive tract dissection, destroying organic matter and identifying microplastics using a microscope. Destruction of organic matter was carried out by adding a 30% H2O2 solution to the digestive tract which had previously been weighed dry weight with a ratio of 1:20, then incubated for 24 hours. Three types of microplastics were found in all samples of the digestive tract with the dominance of films (54%), followed by fragments (33%) and fiber (13%). Among the types of microplastics, film is the type of microplastic which has the highest abundance (2.30 ± 1.30 particles/gr). This study found that fish size has a low relationship with the abundance of microplastics in the digestive tract of fish. This can be attributed to the eating habits of fish, fish food, mouth size and different levels of water pollution.

Antibiotik merupakan obat yang berasal dari mikroorganisme dan digunakan untuk mengobati infeksi bakteri. Salah satu dari jenis antibiotik yaitu kloramfenikol. Kloramfenikol merupakan antibiotik berspektrum luas yang memiliki aktivitas melawan mikroorganisme patogen. Kloramfenikol banyak digunakan karena harganya yang relatif murah, saat ini penggunaan kloramfenikol telah dilarang sebagai antibiotik budidaya karena ketidaksadaran para pembudidaya dalam menggunakan antibiotik seperti kloramfenikol ternyata menimbulkan efek negatif. Berkaitan dengan hal tersebut, pemantauan residu antibiotik kloramfenikol dilakukan untuk menjamin keamanan pangan produk perikanan. Penelitian ini telah dilaksanakan di UPT. PMP2KP Surabaya, Jawa Timur yang dilaksanakan pada bulan Februari2022. Metode deteksi antibiotik pada sampel produk perikanan yang dugunakan adalah metode ELISA. Pengujian residu kloramfenikol menunjukkan semua sampel mengandung residu kloramfenikol dengan konsentrasi antara 0,005 - 0,020 ppb. Meskipun terdapat residu yang masih terdeteksi pada pengujiannya yang dilakukan, namun nilai tersebut masih di bawah batas maksimum yang ditetapkan pada SNI 01-6366-2000 tentang kandungan kloramfenikol pada produk perikanan sebesar 0,01 mg/kg. Nilai konsentrasi yang terdeteksi juga masih memungkinkan menjadi produk Eksport ke negara-negara Eropa dan Amreka. Di Negara seperti Uni Eropa (EU) dan Amerika Serikat (FDA) telah menetapkan batas maksimum residu kloramfenikol yang diijinkan tidak lebih dari sebesar 0,3 ppb. Sementara - Rusia menetapkan batas residu kloramfenikol sebesar 0,5 unit/g, dan China sebesar 0,5 g/kg. Mengacu pada standar tersebut, maka produk perikanan yang telah diuji pada penelitian ini masih memungkinkan menjadi komoditas ekspor. Antibiotics are drugs derived from microorganisms used to treat bacterial infections. One of the antibiotics is chloramphenicol. Chloramphenicol is a broad-spectrum antibiotic that has activity against pathogenic microorganisms. Chloramphenicol is widely used because the price is relatively cheap. Currently, the use of chloramphenicol has been banned as a cultured antibiotic because the farmers' ignorance of using antibiotics such as chloramphenicol turns out to have negative effects. Misuse of these antibiotics can result in chemical residues being left behind in cultivated meat products which can have an impact on the health of consumers. Food safety has become a global issue with various cases of poisoning and diseases due to chemicals found in fishery products. Therefore, several analyses or tests are needed to observe the quality and content of fishery products with qualified facilities. This research has been carried out at UPT. PMP2KP Surabaya, East Java, was held on January 17-18 February 2022. Tests for chloramphenicol residues showed that all samples contained chloramphenicol residues with concentrations between 0.005-0.020 ppb which was still below the maximum limit according to SNI 01-6366-2000 chloramphenicol content of 0.01 mg/kg. Countries such as the European Union (EU) and the United States (FDA) set a maximum limit for chloramphenicol residues of 0.3 ppb. The Russian state sets the limit for chloramphenicol residues at 0.5 units/g and China at 0.5 g/kg.

Sedangkan nilai konsentrasi logam berat Cr total pada sampel air didapatkan kisaran 0,16-0,32 ppm. Berdasarkan konsentrasi tersebut, analisis jaringan insang G. affinis ditemukan jenis kerusakan berupa edema, hiperplasia dan fusi lamela. Hasil analisis parameter kualitas air, ditemukan nilai parameter suhu dan BOD berada di atas nilai baku mutu yang sudah ditentukan. Kesimpulan dari hasil penelitian menunjukkan bahwa Sungai kresek mengalami pencemaran logam berat Cu dan Cr total sehingga menyebabkan kerusakan jaringan insang G. affinis. Inputs influence changes in the quality of the waters of the Kresek River in the form of industrial waste, domestic activities, or agricultural activities. The resulting waste was identified as Cu and Cr total heavy metal waste. The toxicological point of view states that Cu and total Cr can affect organ function in fish organisms. Continuous exposure to the heavy metals Cu and Cr in the gills causes bleeding and breakdown of the gill cells. Damage to fish gill tissue can be analyzed as a process of biomonitoring the health of the aquatic environment. The biomonitoring agent used in the analysis process is G. affinis. This study aims to investigate the damage to the gill tissue of G. affinis due to Cu and total Cr heavy metal contamination in the Kresek River. The research method used is a descriptive method with a survey approach. The analysis results showed that the heavy metal Cu concentration in the water samples was in the range of 0.13-0.24 ppm. Meanwhile, the total Cr heavy metal concentration value in water samples was found in the 0.16-0.32 ppm range. Based on these concentrations, analysis of the gill tissue of G. affinis found types of damage in the form of edema, hyperplasia, and lamella fusion. The results of the study of water quality parameters, it was found that the parameter values for temperature and BOD were above the predetermined quality standard values. The research results concluded that the Kresek River was polluted by heavy metals Cu and total Cr, which caused damage to the gill tissue of G. affinis.

Kematian massal ikan merupakan salah satu permasalahan utama yang dihadapi di Ranu Klakah. Hal ini diakibatkan oleh proses kompleks seperti akumulasi bahan organik baik pada dasar perairan maupun kolom air, serta fenomena up welling yang terjadi secara rutin setiap tahun di perairan tersebut. Pada tahap awal penumpukkan bahan organik di dasar perairan mengakibatkan pembentukan lapisan anaerobik yang makin besar dan senyawa beracun seperti H2S dan NH3. Tujuan dari penelitian ini adalah untuk menganalisis status kualitas air, dinamika kadar bahan organik yang disebabkan fenomena up welling, dan hubungan bahan organik dengan parameter kualitas air di Ranu Klakah. Analisis data yang digunakan untuk mengetahui hubungan kualitas air terhadap kelimpahan konsorsium mikroorganisme dengan menggunakan bentuk uji korelasi pearson. Parameter kualitas air yang diukur pada aspek fisika: warna, bau, rasa,temperatur, dan kecerahan/ cuaca, lalu aspek kimia yang diperiksa/diukur langsung di lapangan seperti pH, dissolved oxygen (DO), Biological Oxygen Demand (BOD) dan amonia. Hasil pengukuran parameter bahan organik di Ranu Klakah selama sebelum dan pada saat up welling sangat fluktuatif. Nilai Bahan Organik Ranu Klakah terendah terjadi saat sebelum up welling yaitu pada stasiun outlet dengan nilai bahan organik 3,03% nilai terendah pada saat up welling pada stasiun Inlet dengan nilai bahan organik 7,31%. Hasil analisis hubungan beberapa kualitas air dengan bahan organik pada Ranu Klakah yaitu berpengaruh nyata. Hasil pengukuran pada parameter kualitas air suhu yaitu antara 27°C – 28 °C, nilai pH pada perairan yaitu 7, DO pada perairan antara 11,8 mg/L – 13,3 mg/L, nilai BOD antara 1,8 mg/L – 3,1 mg/L, konsentrasi amonia pada perairan 0,15, konsentrasi nitrat yaitu 0 mg/l dan konsentrasi nitrit diantara 25-50 mg/l. The problem in Ranu Klakah is the mass death of fish caused by a complex process due to the accumulation of organic matter on the bottom of the water and the water column. This problem results from the phenomenon of upwelling that occurs routinely every year in these waters. In the early stages, due to the build-up of organic matter on the bottom of the water, a more extensive anaerobic layer is formed, followed by toxic compounds such as H2S and NH3. This study aims to analyze the status of water quality and determine the dynamics of organic matter levels caused by the phenomenon of upwelling and the relationship of organic matter with water quality parameters in Ranu Klakah. Research analysis to determine the relationship of water quality to the abundance of microorganism consortiums using the Pearson correlation test form. Water quality parameters are measured in physical aspects: colour, smell, taste, temperature, and brightness/weather, then chemical aspects that are examined/measured directly in the field, such as pH, dissolved oxygen (DO), Biological Oxygen Demand (BOD) and ammonia. The results of measuring organic matter parameters in Ranu Klakah before and during upwelling fluctuate. Ranu Klakah Organic Material value: The lowest value before upwelling is at the outlet station, with an organic matter value of 3.03%. The lowest value at the upwelling at the Inlet station is with an organic matter value of 7.31%. The analysis results of the relationship between some water quality and organic matter in Ranu Klakah have a natural effect. The measurement results on temperature water quality parameters are between 27 °C – 28 °C, pH values in waters are 7, DO in waters between 11.8 mg / L - 13.3 mg / L, BOD values between 1.8 mg / L - 3.1 mg / L, ammonia concentrations in waters 0.15, nitrate concentrations are 0 mg / l and nitrite concentrations between 25-50 mg / l.

Alur Pelayaran Barat Surabaya (APBS) merupakan salah satu alur pelayaran penting di Indonesia letaknya ada di Selat Madura. Perairan dengan tingkat aktivitas kapal yang tinggi rentan terjadi tumpahan minyak dari aktivitas kapal maupun kecelakaan kapal. Salah satu upaya untuk mengetahui arah persebaran tumpahan minyak di perairan adalah dengan memodelkan tumpahan minyak menggunakan perangkat lunak, salah satunya adalah perangkat lunak MIKE Zero. Dari hasil pemodelan yang dilakukan, dapat dianalisis daerah mana saja yang terdampak jika terjadi tumpahan minyak di Perairan Selat Madura khususnya di APBS. Dari hasil pemodelan hidrodinamika, diketahui bahwa arus di wilayh APBS tergolong kecil dengan rata- rata arus pada setiap musim sebesar 0.06 m/s. Rata-rata arus tertinggi terdapat pada musim barat yaitu bulan Januari 2023. Dari hasil model tumpahan minyak selama 4 musim, Januari 2023 memiliki luasan tumpahan paling luas yaitu sebesar 847.089 m2 tepatnya pada 7 Januari 2023 atau 1 minggu pasca tumpahan dan dominan menyebar ke arah barat laut dan timur. Hasil simulasi menunjukkan bahwa pada keempat musim menunjukan bahwa tumpahan dominan bergerak ke barat laut dan tenggara dari titik tumpahan dan tidak ada yang mencapai ke pesisir dan hanya mencemari perairan saja. Pencemaran ini dapat menurunkan kualitas air dan dapat mengganggu kehidupan biota. West Surabaya Shipping Route which is one of the most important shipping channels in Indonesia is located in Madura Strait. Waters with high levels of ship activity are prone to oil spills from ship activity or ship accidents. One effort to determine the direction of the spread of oil spills in waters is to model oil spills using software, one of which is MIKE Zero software. From the results of the modeling, it can be analyzed which areas will be affected if an oil spill occurs in the waters of Madura Strait, especially in West Surabaya Shipping Channel. From the results of hydrodynamic modeling, it is known that the current in the West Surabaya Shipping Channel is relatively small with an average current in each season is 0.06 m/s. The highest average flow is in the west season, on January 2023. From the results of the oil spill model for 4 seasons, January 2023, has the largest spill area, 847,089 m2, precisely on January 7 2023 or 1 week after the spill and is dominant spread to the northwest and east. The simulation results show that in the four seasons, the dominant spill moves to the northwest and southeast from the spill point and none reaches the coast and only pollutes the waters. This pollution can reduce water quality and disrupt biota life.
