Senyawa kimia yang berasosiasi dengan sampah plastik di laut dapat terjadi karena bahan dari produk plastik itu sendiri atau kontaminan kimia yang berada di lautan dan terakumulasi pada plastik saat menjadi sampah laut. Senyawa kimia yang berasosiasi dengan sampah plastik di lautan adalah POPs, PAH, TPH. Kelompok senyawa tersebut umumnya menyebabkan pencemaran lingkungan dan masalah kesehatan seperti kanker, alergi serta iritasi, mutasi genetik dan merusak susunan saraf. Tujuan dari penelitian ini adalah mengidentifikasi komposisi senyawa organik volatil yang berasosiasi dengan makroplastik di pantai selatan, Kabupaten Malang serta mengetahui persentase dari senyawa kimianya dan mengetahui potensi dampak dari senyawa organik volatil yang berasosiasi dengan sampah laut. Pengambilan sampel penelitian dibuat menjadi enam stasiun di sepanjang Pesisir Kabupaten Malang. Sampah akan diambil menggunakan metode purposive sampling dan metode composite sampling. Sampel yang sudah dikumpulkan dipotong kecil lalu diekstraksi dengan metode maserasi menggunakan pelarut benzena dan setelah itu diidentifikasi menggunakan GC-MS. Hasil penelitian menunjukkan bahwa terdapat enam senyawa kimia yang dominan yaitu seperti trans -2-Chloro -3 - (1,1 - dimethylehyl) cyclohexanone (PAH); 3-Methyl-1,1-diphenyl-1,2-butanediol (POP); 4,4-Dimethyl-1-hydroxy-2-cyclopentene (POP); 7-Hydroxy-7-phenyl-3,9-diisopropyl-2,10-dioxadispiro (TPC); Benzenemethanol,.alpha.-phenyl-(CAS), Diphenylmethanol (PAH); Cyclohexanone,3-(3,3-dimethylbutyl) (CAS) (3,3Dimethylbuthyl) Cyclohe xanone (POP). Hampir semua senyawa kimia yang teridentifikasi berpengaruh buruk terhadap lingkungan. Senyawa-senyawa tersebut merupakan bahan baku dari pembuatan produk plastik, parfum, deterjen, solar, alat kosmetik, serta bahan kimia farmasi. Chemical compounds associated with plastic waste in the sea can occur due to materials from the plastic product itself or chemical contaminants that are in the ocean and accumulate in plastic when it becomes marine waste. Chemical compounds associated with plastic waste in the ocean are POPs, PAH, and TPH. These groups of compound generally cause environmental pollution and health problems such as cancer, allergies and irritation, genetic mutations and damage to the nervous system. The aim of this study was to identify the composition of volatile organic compounds associated with macroplastics in South Coastal of Malang, as well as to determine the percentage of chemical compounds and determine the potential impact of volatile organic compounds associated with marine debris. The plastic samples were collected from six stations in the coastal of Malang Regency. Plastic wastes were collected using the purposive sampling method and composite sampling method. The samples that had been collected were cut into small pieces and then extracted using the maceration method using benzene solvent and then identified using GC-MS. The results showed that there were six dominant chemical compounds, namely trans - 2 - Chloro - 3 - (1,1 - dimethylehyl) cyclohexanone (PAH); 3-Methyl-1,1-diphenyl-1,2-butanediol (POP); 4,4-Dimethyl-1-hydroxy-2-cyclopentene (POP); 7-Hydroxy-7-phenyl-3,9-diisopropyl-2,10-dioxadispiro (TPC); Benzenemethanol,.alpha.-phenyl-(CAS) Diphenylmethanol (PAH); Cyclohexanone,3-(3,3-dimethylbutyl)-(CAS) (3,3Dimethylbuthyl) Cyclohexanone (POP). Almost all chemical compounds which had been identified showed negative effects in the environment. These compounds are raw materials for the manufacture of plastic products, perfume, detergent, diesel, cosmetic equipment, and pharmaceutical chemicals.

Hasil rata-rata pengujian kandungan logam berat tertinggi terdapat pada sampel sedimen (Pb) yaitu sebesar 12,30 mg/kg dan terendah (Cd) sebesar 0,0171 mg/kg. Pada sampel air tertinggi pada (As) sebesar 0,0158 mg/kg dan terendah (Pb dan Cd) yaitu tidak terdeteksi. Pada ikan kerapu cantang logam berat tertinggi pada (As) sebesar 0,7515 mg/kg dan terendah pada (Cd) 0,0014 mg/kg. Sedangkan hasil pengujian pada indeks EF nilai tertinggi terukur pada logam berat Kadmium (42,75), nilai tertinggi Igeo, CF dan BCF secara berturut-turut adalah pada logam berat Arsen (1,06 ; 3,12 ; 49,88). Lamongan is a district that plays an important role in supporting the economy so that various kinds of industries are built and maximized to meet the needs of the community. The increase in population density causes an increase in consumption rates which is accompanied by industrial development, thereby making room for polluting materials. One of the pollutants that has a long-term negative impact is heavy metals. In this study, the giant hybrid grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus) was used as the object of research. The purpose of this study was to determine the content of heavy metals Pb, Cd and As and to determine the pollution index and accumulation status of Cantang grouper, water and sediment in traditional ponds in Brondong, Lamongan, East Java. The research method used is observational and descriptive as a type of research design and the data analysis used is quantitative with calculations on the EF, Igeo, CF and BCF indexes. Samples of Cantang grouper and water will be tested for heavy metal content at the Integrated Service Unit Laboratory for Quality Testing and Development of Marine and Fishery Products (UPT PMPPKP) Surabaya, while the sediment will be tested for Angler Chemical at the Laboratory in Surabaya. The results of the average test for the highest heavy metal content were found in the sediment sample (Pb) which was 12.30 mg/kg and the lowest (Cd) was 0.0171 mg/kg. In the water sample, the highest (As) was 0.0158 mg/kg and the lowest (Pb and Cd) were not detected. In hybrid giant grouper, the highest heavy metal was at (As) of 0.7515 mg/kg and the lowest was at (Cd) of 0.0014 mg/kg. While, in the test results on the EF index, the highest value was measured for heavy metal Cadmium (42.75), and the highest values for Igeo, CF, and BCF, respectively, were heavy metal Arsenic (1.06; 3.12; 49.88).

Mikroplastik adalah jenis sampah plastik yang memiliki ukuran partikel lebih kecil dari 5 mm. Dengan ukuran yang sangat kecil dapat menyebabkan mikroplastik tidak dapat terdegradasi dengan sempurna. Hal tersebut menjadikan mikroplastik sebagai polutan terhadap lingkungan baik di darat dan laut dalam jangka waktu yang panjang. Tujuan penelitian ini yaitu untuk identifikasi jenis mikroplastik dan kelimpahan mikroplastik di sedimen Pulau Perak, Jakarta Indonesia. Penelitian menggunakan metode purposive sampling. Pengambilan sampel sedimen menggunakan empat stasiun yaitu wilayah utara, timur, barat, dan selatan Pulau Perak. Hasil identifikasi mikroplastik ditemukan tiga jenis mikroplastik, yaitu fiber, film, dan fragmen. Jenis mikroplastik yang ditemukan berjumlah 311 partikel. Kelimpahan mikroplastik di sedimen yaitu 5.380 partikel/gram. Kelimpahan jenis mikroplastik paling tinggi ditemukan di stasiun timur sebesar 1.480 partikel/gram. Sedangkan kelimpahan mikroplastik di stasiun utara 1.440 partikel/gram, stasiun selatan 1.260 partikel/gram, dan stasiun barat 1.200 partikel/gram. Microplastics are a type of plastic waste that has a particle size smaller than 5 mm. The very small size can cause microplastics to not be completely degraded. This becomes microplastic as a contaminant polluting the environment both on land and sea over a long period of time. The aim of this research is to identify the types of microplastics and the abundance of microplastics in the sediments of Perak Island, Seribu Islands, Jakarta. Sediment sampling used four stations, namely the north, east, west and south of Perak Island. The results of microplastic identification found three types of microplastics, fiber, film and fragments. The types of microplastics found totaled 311 particles. The abundance of microplastics in the sediment was 5,380 particles/gram. The highest abundance of microplastics was found at the east station at 1,480 particles/gram. Meanwhile, the abundance of microplastics at the north station was 1,440 particles/gram, at the south station was 1,260 particles/gram, and at the west station was 1,200 particles/gram.

Pseudo-nitzschia spp. merupakan suatu jenis diatom kosmopolitan yang berpotensi menyebabkan Harmful Algal Blooms (HABs) yang menghasilkan toksin asam domoat, penyebab sindrom amnesic shellfish poisoning (ASP). Penelitian bertujuan untuk mengetahui faktor-faktor lingkungan yang mempengaruhi kelimpahan Pseudo-nitzschia spp. di Perairan Teluk Hurun selama periode Agustus 2020 hingga Juli 2021. Sampling air dan fitoplankton dilakukan di tiga stasiun pengamatan, analisis dilakukan menggunakan metode regresi linier Backward. Hasil regresi menunjukkan bahwa nitrit, nitrat dan amonia secara signifikan berpengaruh terhadap kelimpahan Pseudo-nitzschia spp. dengan nilai p-value berturut-turut adalah 0,000 untuk variabel nitrit, 0,030 untuk variabel nitrat dan 0,015 untuk variabel amonia. Hasil penelitian menunjukkan bahwa terdapat hubungan positif antara konsentrasi nitrit, nitrat dan amonia dengan kelimpahan Pseudo-nitzschia spp. Hal ini mengindikasikan bahwa peningkatan zat hara dapat memicu pertumbuhan alga berbahaya. Hal ini menekankan perlunya dilakukan langkah-langkah strategis untuk mengelola eutrofikasi dan dampak perubahan iklim untuk mengurangi risiko kejadian HABs di Perairan Teluk Hurun. Pseudo-nitzschia spp. is a cosmopolitan diatom species that has the potential to cause Harmful Algal Blooms (HABs) which produces domoic acid toxin, the cause of amnesic shellfish poisoning syndrome (ASP). The study aims to determine the environmental factors that affect the abundance of Pseudo-nitzschia in Hurun Bay Waters during the period August 2020 to July 2021. Water and phytoplankton sampling was conducted from three observation stations, the analysis was conducted using the Backward linear regression method. The regression results showed that nitrite, nitrate and ammonia significantly influenced the abundance of Pseudo-nizschia spp. with p-values of 0.000 for the nitrite variable, 0.030 for the nitrate variable and 0.015 for the ammonia variable, respectively. The results showed that there was a positive relationship between nitrite, nitrate and ammonia concentrations and the abundance of Pseudo-nitzschia spp. This indicates that an increase in nutrients can trigger harmful algal growth. This emphasizes the need for strategic measures to manage eutrophication and climate change impacts to reduce the risk of HABs occurrence in Hurun Bay Waters.

Mikroplastik memiliki potensi tinggi untuk tersebar merata di perairan dan terakumulasi pada organisme perairan termasuk ikan. Saluran pencernaan dan organ insang merupakan bagian ikan yang seringkali terkontaminasi oleh mikroplastik. Penelitian ini bertujuan untuk menganalisis komposisi mikroplastik pada ikan Clupea harengus, Euthynnus affinis, dan Restrelliger brachysoma dengan lokasi yang berbeda diantaranya Pondok Dadap Sendang Biru, Pacitan, dan Mayangan Probolinggo. Analisis dilakukan dengan identifikasi organ dan saluran pencernaan pada ketiga spesies ikan. Komposisi mikroplastik pada sampel organ ikan dianalisis dengan menghancurkan bahan organik melalui perendaman sampel pada laruta H2O2 30% dan larutan Fe (II) 0,05 M selama 24 Jam. Analisis dilanjutkan dengan penyaringan sampel menggunakan kertas Whatman dan identifikasi menggunakan mikroskop (Olympus CX33). Diantara jenis mikroplastik, fiber dan fragmen merupakan jenis mikroplastik yang paling banyak ditemukan pada ikan Clupea harengus, Euthynnus affinis, dan Restrelliger brachysoma dibandingkan dengan jenis film. Kelimpahan total mikroplastik ditemukan lebih tinggi pada organ dibandingkan pada saluran pencernaan. Terdapat perbedaan jumlah kelimpahan mikroplastik pada ketiga spesies. Spesies Clupea harengus memiliki kelimpahan mikroplastik tertinggi dibandingkan dengan spesies lainnya. Hal ini dipengaruhi oleh kondisi ikan yang tidak dapat membedakan antara mikroplastik dan plankton sebagai mangsanya. Kebiasaan makan ikan dengan menyaring air di sekitarnya membuat ikan rentan mendapatkan plankton yang terkontaminasi mikroplastik. Microplastics have a high potential to be evenly distributed in waters and accumulate in aquatic organisms including fish. The digestive tract and gill organs are parts of fish that are often contaminated by microplastics. This study aims to analyze the composition of microplastics in fish Clupea harengus, Euthynnus affinis, and Restrelliger brachysoma with different locations including Pondok Dadap Sendang Biru, Pacitan, and Mayangan Probolinggo. The analysis was conducted by organ identification in the three fish species. The composition of microplastics in fish organ samples was analyzed by destroying organic matter through immersion of samples in 30% H2O2 solution and 0.05 M Fe (II) solution for 24 hours. The analysis was continued by filtering the samples with Whatman paper and identifying them with a microscope (Olympus CX33). Among the types of microplastics, fibers and fragments were the most common types of microplastics found in Clupea harengus, Euthynnus affinis, and Restrelliger brachysoma compared to film types. The total abundance of microplastics was found to be higher in organs than in the digestive tract. There were differences in the abundance of microplastics among the three species. Clupea harengus species had the highest abundance of microplastics compared to other species. This is influenced by the condition of the fish, which cannot choose between microplastics and plankton as prey. Fish feeding habits by filtering the surrounding water make fish vulnerable to plankton contaminated with microplastics.

Ikan kembung (Rastrelliger kanagurta) dan ikan lemuru (Sardinella lemuru) merupakan dua spesies ikan yang umum ditangkap di PPP Mayangan Probolinggo dan memiliki peluang yang tinggi untuk terkontaminasi oleh mikroplastik. Sampel ikan diambil secara acak dan diukur morfometrik (panjang dan berat tubuh) sebagai informasi biologis pendukung dan validasi untuk penggunaan uji perbedaan morfometrik dari kedua jenis ikan terhadap data kelimpahan mikroplastiknya. Analisis kelimpahan mikroplastik pada kedua jenis ikan dilakukan dengan mengidentifikasi dan membandingkan kelimpahan partikel antara kedua jenis ikan berdasarkan jaringan/organ ikan, tipe partikel, ukuran partikel, serta warna partikel. Bahan organik dihancurkan menggunakan metode destruksi H2O2 30% dengan perbandingan 1:20. Analisis FTIR digunakan untuk mengetahui jenis polimer dari mikroplastik. Hasil menunjukkan terdapat kelimpahan sebanyak 52,20 ± 22,81 partikel/individu pada ikan kembung dan 61,20 ± 10,48 partikel/individu pada ikan lemuru. Analisis statistik menunjukkan tidak adanya perbedaan kelimpahan partikel yang signifikan berdasarkan asal organ/jaringan maupun tipe, ukuran, dan warna partikel. Dapat disimpulkan bahwa partikel mikroplastik yang dikonsumsi oleh kedua jenis ikan cenderung memiliki karakteristik yang sama: bertipe fragmen atau fiber, berwarna hitam atau biru, dan berukuran berkisar 50-100 µm. Hasil FTIR menunjukkan partikel dengan tipe cotton fibre. Kontrol kualitas data mikroplastik dari sampel (tingkat kontaminasi udara 1,59 %) didapatkan dari blanko (kontrol negatif) dengan mempertimbangkan kelimpahan dan karakteristik mikroplastiknya. Mackerel (Rastrelliger kanagurta) and the Bali Sardinella (Sardinella lemuru) are two common fish species caught in the Mayangan Probolinggo Fishing Port (PPP) and are highly susceptible to microplastic contamination. Fish samples were picked randomly and their morphometric (body length and weight) were measured as supporting biological information and validation for the usage of difference testing of both species’ morphometrics to their microplastics abundance. Analysis of microplastic abundance in both fish species was conducted by identifying and comparing particle abundance between the two species based on fish tissues/organs, particle type, particle size, and particle colour. Organic material was destroyed using a 30% H2O2 destruction method with a ratio of 1:20. FTIR was performed to determine the polymer of microplastics. The results showed an abundance of 52.20 ± 22.81 particles/individual in mackerel and 61.20 ± 10.48 particles/individual in Bali Sardinella. Statistical analysis indicated no significant differences in particle abundance based on organ/tissue origin or particle type, size, and colour. It can be concluded that the microplastic particles consumed by both fish species tend to have similar characteristics: fragmented or fibrous type, black or blue colour, and a size of 50-100 µm. FTIR results indicated cotton fibre type particle. Quality control of the microplastic data from samples (air contamination level of 1,59%) was obtained from blank samples (negative control) with their abundance and characteristics taken into consideration.

Ekosistem mangrove adalah salah satu ekosistem di kawasan pesisir yang memiliki peran krusial bagi lingkungan. Pemantauan terhadap kondisi perairan mangrove sangat penting dilakukan guna menjaga keberlanjutannya. Salah satu bioindikator yang dapat digunakan untuk tujuan ini adalah diatom. Penelitian ini bertujuan untuk menganalisis komposisi diatom di berbagai habitat (akar, kolom air dan sedimen mangrove) dan memanfaatkan mikroorganisme ini sebagai agen bioindikator pencemaran di ekosistem mangrove Muara Bajulmati. Kegiatan penelitian dilaksanakan selama Maret hingga April 2024 di tiga stasiun pengambilan sampel. Data yang dikumpulkan meliputi komposisi diatom dan hasil pengukuran parameter kualitas air fisika dan kimia. Analisis data yang digunakan adalah indeks keanekaragaman, indeks keseragaman dan indeks dominansi. Hasil penelitian menunjukkan bahwa terdapat 15 – 17 genus yang teridentifikasi pada akar, kolom air, dan sedimen mangrove Muara Bajulmati. Kondisi perairan di lokasi penelitian juga mendukung pertumbuhan diatom secara optimal. Selain itu, berdasarkan nilai indeks biologi yang diperoleh, maka habitat kolom air dan stasiun pengambilan sampel pertama memiliki kondisi perairan yang terbaik di kawasan mangrove Muara Bajulmati. The mangrove ecosystem is one of the ecosystems in coastal areas that has a crucial role for the environment. Monitoring the condition of mangrove waters is very important to maintain their sustainability. One bioindicator that can be used for this purpose is diatoms. This research aims to analyze the composition of diatoms in various habitats (roots, water column and mangrove sediment) and utilize these microorganisms as a bioindicator agents for pollution in the Bajulmati estuary mangrove ecosystem. Research activities were carried out from March to April 2024 at three sampling stations. The data collected includes diatom composition and measurement results of physical and chemical water quality parameters. The data analysis used is the diversity index, uniformity index and dominance index. The research results showed that there were 15 - 17 genera identified in the roots, water column and sediments of the Bajulmati estuary mangroves. Water conditions at the research location also support optimal diatom growth. In addition, based on the biological index values obtained, the water column habitat and the first sampling station have the best water conditions in the Muara Bajulmati mangrove area.
