Abstract

Microplastic pollution has become a serious issue worldwide. Once it enters the environment, microplastics could accumulate in the water column and sediment. This study aimed to analyze the occurrence of microplastics in the beach sediments along the western coast of Situbondo, East Java. Sediment samples were collected in the strandline areas from seven different beaches that received the high impact of human activities. In the laboratory, sediment samples were oven-dried and weighed, density separation was performed using NaCl solution, degradation of organic matter was conducted using H2O2 30% and microplastic particles were identified using a microscope. In total, 1041 microplastic particles were retrieved from 21 sediment samples consisting of fiber (50 %), fragment (37 %), microbeads (11 %), and film (2 %). Microplastics found in this study consists of blue color (49 %), red (26 %), white (11 %), brown (7 %), and other colors such as yellow, black, green, and transparent with a percentage between 1?3 %. Microplastics with a size of < 300 µm dominate the result of this study. Microplastic abundances were found in the range of 204.52?492.50 particles/kg sediment sample. In each sampling location, the types of microplastic were found in a different pattern. Fiber and fragments were found in all sampling sites, while film and microbeads were found only in specific sites. This study showed that several factors, such as plastic sources and hydro-oceanography parameters, influenced the occurrence of microplastics in the sampling sites. In order to address microplastic pollution in the marine environment, plastic waste management strategies are required.Keywords: Fishing port, Mangrove, Marine Pollution, Plastics, Tourism

Abstract

Penyakit Minamata adalah kondisi yang disebabkan oleh keracunan merkuri akibat pencemaran lingkungan, yang pertama kali teridentifikasi di Kota Minamata, Jepang, pada tahun 1956. Artikel ini dituliskan dengan tujuan untuk menjelaskan proses perubahan merkuri anorganik menjadi metil merkuri (merkuri organik), menjelaskan proses bioakumulasi dan biomagnifikasi metil merkuri pada biota dan manusia serta dampaknya terhadap kesehatan ekosistem dan manusia. Metode yang digunakan adalah kualitatif deskriptif dengan studi literatur untuk mengumpulkan data relevan dari berbagai sumber. Berdasarkan analisis pustaka yang telah dilakukan menunjukkan bahwa limbah industri yang mengandung merkuri anorganik dapat berubah menjadi metil merkuri yang lebih berbahaya, mengakibatkan akumulasi dalam rantai makanan, terutama pada ikan yang dikonsumsi oleh masyarakat. Rekomendasi yang dihasilkan adalah perlunya pengelolaan lingkungan yang lebih baik dan kesadaran masyarakat untuk mencegah terulangnya tragedi  Minamata di masa depan.

Abstract

Sampah laut merupakan residu yang dihasilkan dari kegiatan manusia yang dapat terakumulasi di pesisir. Sampah laut, terutama kategori plastik memiliki sifat persisten yang sulit diurai di lingkungan, sehingga dapat membahayakan. Penelitian ini bertujuan untuk mengkaji komposisi dan distribusi spasial sampah laut di pesisir Pantai Drop Off dan Pantai Batu Niti, Bali pada bulan Juni dan Agustus 2023. Pengambilan sampah laut dilakukan menggunakan transek 5 x 5 m, yang selanjutnya dianalisis berdasarkan jenis, ukuran, dan kelimpahannya. Sampah laut kategori plastik lebih lanjut dianalisis menggunakan Plastic Abundance Index (PAI). Berdasarkan kelimpahannya, sampah laut yang ditemukan di Pantai Batu Niti sedikit lebih rendah (1,1 ± 0,8 item/m²) dibandingkan di Pantai Drop Off (2,4 ± 1,3 item/m²). Sementara itu, berdasarkan ukurannya sampah laut yang ditemukan di Pantai Batu Niti lebih bervariasi, sedangkan di Pantai Drop Off sampah dengan ukuran 10 cm – 1 m ditemukan lebih mendominasi (49,81%) dibandingkan ukuran lainnya. Pada kedua pantai, jenis plastik ditemukan jauh lebih banyak dibandingkan jenis sampah lainnya, yaitu 87,9% di Pantai Batu Niti dan 67,6% di Pantai Drop Off. Hasil perhitungan Plastic Abudance Index (PAI) menunjukkan bahwa pencemaran plastik di Pantai Batu Niti (13 ± 7,9) dan Pantai Drop Off (17,5 ± 9,5) termasuk kategori sangat tinggi yang diduga karena aktivitas antropogenik berupa kegiatan wisatawan serta konektivitas perairan dengan wilayah permukiman terhadap kegiatan perikanan. Temuan ini menekankan perlunya strategi pengelolaan limbah yang lebih baik, terutama di kawasan wisata dan permukiman pesisir, untuk mengurangi pencemaran plastik.

Abstract

Microplastic (MP) pollution is a growing environmental concern due to its persistence in aquatic ecosystems. Among MPs, large microplastics (1–5 mm) originate from the degradation of larger plastic debris and pose ecological risks. However, research on their accumulation in mangrove sediments remains limited. This study investigates the characteristics, abundance, and spatial distribution of large microplastics in the Wonorejo Mangrove Tourism Area, Surabaya, which receives plastic waste transported by the Wonorejo River. Surface sediment samples were collected from three stations, followed by drying, sieving, visual inspection, and Fourier Transform Infrared (FTIR) spectroscopy for polymer identification. The results indicate that film-type microplastics were the most abundant (72%), followed by fragments (23%) and pellets (5%). Transparent microplastics (38%) were the dominant color, followed by blue (26%). The highest microplastic concentration was recorded at Station 2 (130.7 ± 73.5 particles/kg), while Station 1 had the lowest (2.7 ± 2.7 particles/kg). Despite these variations, statistical analysis showed no significant differences in microplastic distribution among stations, suggesting a relatively homogeneous spatial pattern across the study area. FTIR analysis identified two dominant polymers: polypropylene (PP) and polyethylene (PE), commonly used in consumer and industrial products. The predominance of film-type microplastics and transparent coloration suggests that the primary sources of contamination are plastic bags and food packaging waste transported by river currents. These findings underscore the role of mangrove ecosystems as critical retention zones for plastic pollution, highlighting the urgent need for improved waste management strategies to mitigate microplastic accumulation in coastal environments.

Abstract

This study attempted to analyze the distribution and contamination status of heavy metals (Cu, Fe and Zn) along western coast of Bali Strait in Banyuwangi, East Java. Bali Strait is one of the many straits in Indonesia with high fisheries activities that could potentially contributed to high heavy metal pollution. There were five sampling areas from the north to south: Pantai Watu Dodol, Pantai Kalipuro, Ketapang Port, Pantai Boom and Muncar as the fish landing area. Heavy metal pollution in these locations comes from many different activities such as tourism, fish capture and fish industry and also domestic activities. Contamination factor (CF), geo-accumulation index (Igeo) and enrichment factor (EF) of each heavy metal were calculated to obtain contamination status of the research area. The concentrations of Fe were observed the highest (1.5-129.9 mg/kg) followed by Zn (13.2-23.5 mg/kg) and Cu (2.2-7.8 mg/kg). The distribution of Cu, Fe and Zn showed variability among the sampling locations in which high concentrations of Cu and Zn were higher in Ketapang Port, whereas high concentration of Fe was high in almost all sampling locations. According to the pollution index, contamination factors of Cu, Fe and Zn were low (CF < 1 and Igeo < 1). However, high index of EF (> 50) showed high influence of the anthropogenic activities to the contribution of the metals to the environment. This could also because of the high background value used in the calculation of the index due to the difficulties in finding background value from the sampling areas.Keywords: heavy metals, pollution index, contamination factor, geo-accumulation index, Bali Strait

Abstract

Variabilitas Suhu Permukaan Laut (SPL) dan sebaran klorofil-a di Perairan Muncar (Selat Bali) sangat mempengaruhi hasil tangkapan ikan yang didaratkan di Pelabuhan Perikanan Pantai (PPP) Muncar. Informasi mengenai hal ini penting untuk kajian pendugaan dinamika penangkapan ikan melalui penginderaan jauh. Penelitian ini bertujuan untuk mengetahui variabilitas parameter oseanografi pada tahun 2018 hingga 2022, serta dinamika penangkapan ikan di Perairan Selat Bali, khususnya di PPP Muncar. Data yang digunakan dalam penelitian ini meliputi SPL dan klorofil-a dari satelit Aqua-MODIS level 3 dan data produksi ikan dari PPP Muncar selama 5 tahun. Hasil analisis menunjukkan fluktuasi SPL dan konsentrasi klorofil-a dengan keterkaitan erat antara keduanya. Selama periode tersebut, dinamika penangkapan ikan menunjukkan peningkatan produksi ikan lemuru dan layang pada tahun 2019, meskipun terjadi penurunan produksi pada tahun 2022 akibat peningkatan SPL yang berdampak pada stok ikan. Analisis hubungan antara anomali SPL dan klorofil-a menunjukkan bahwa konsentrasi klorofil-a meningkat saat SPL menurun dengan korelasi -0.378. Fenomena penurunan SPL di perairan Selat Bali menyebabkan adanya peningkatan nilai klorofil-a di perairan yang juga mendukung peningkatan pada hasil produksi ikan. Sedangkan peningkatan SPL yang berkontribusi pada menurunnya hasil produksi ikan. Pemahaman mengenai keterkaitan antara SPL dan klorofil-a dapat digunakan salah satu pertimbangan dalam merumuskan strategi pengelolaan sumber daya ikan yang lebih berkelanjutan, guna meningkatkan produksi perikanan di wilayah tersebut di masa depan.   Sea Surface Temperature (SST) variability and chlorophyll-a distribution in the Muncar Waters (Bali Strait) have been demonstrated to significantly impact the catch of fish landed at Muncar Fishing Port. This information is crucial for the study of estimating fishing dynamics through remote sensing. The present study aims to ascertain the variability of oceanographic parameters from 2018 to 2022, as well as the dynamics of fishing in the Bali Strait Waters, with a particular focus on the Muncar Fishing Port.The study utilizes data from the Aqua-MODIS satellite level 3, which includes SPL and chlorophyll-a measurements, along with fish production data from PPP Muncar over a five-year period. The analysis revealed fluctuations in SST and chlorophyll-a concentrations, with a close relationship between the two parameters. During the observed period, fishing dynamics exhibited an increase in Bali Sardinella and Indian Scad production in 2019, followed by a decrease in 2022, attributed to an increase in SPL, which impacted fish stocks. The analysis revealed a negative correlation between SPL and chlorophyll-a anomalies, with chlorophyll-a concentrations increasing as SPL decreased, as indicated by a correlation coefficient of -0.378. The observed phenomenon of decreasing SPL in the waters of the Bali Strait is concomitant with an increase in chlorophyll-a concentration, thereby supporting an increase in fish production. Conversely, an increase in SPL is associated with a decrease in fish production. A comprehensive understanding of the intricate relationship between SPL and chlorophyll-a can inform the development of more sustainable fish resource management strategies, with the ultimate goal of enhancing fisheries production in the region.

Abstract

AbstractPerairan Malang Selatan merupakan daerah yang potensial sebagai daerah penangkapan ikan. Keberadaan berbagai jenis ikan pelagis kecil terutama ikan planktivor secara langsung dipengaruhi oleh pertumbuhan fitoplankton dan zooplankton. Fitoplankton mempunyai peran penting sebagai dasar rantai makanan dalam ekosistem perairan, sedangkan zooplankton merupakan herbivor pemangsanya. Pertumbuhan fitoplankton dan zooplankton dipengaruhi oleh faktor oseanografinya. Penelitian ini bertujuan untuk mengetahui variasi komunitas plankton dan hubungannya dengan parameter oseanografinya, serta distribusi spasial plankton di daerah penangkapan ikan di Perairan Malang Selatan, Jawa Timur. Metode purposive sampling dengan teknik zigzag pada 10 titik sampling digunakan dalam pengambilan data pada penelitian ini. Sedwicgk rafter counting cell digunakan dalam metode penghitungan plankton. Sampel plankton diambil secara horizontal dan vertikal pada kedalaman 1 dan 15 m dengan jaring plankton bermata jaring 20 µm, sedangkan parameter oseanografi secara in situ diukur menggunakan aqua quality sensor tipe AAQ 1183 C. Hasil penelitian menunjukkan bahwa kelimpahan fitoplankton sebesar 49.764 sel/m3, didominasi oleh genus Chaetoceros. (Bacillariophyceae), dan kelimpahan zooplankton sebesar 894 ind/m3, didominasi oleh genus Nauplius. (Copepoda). Indeks keanekaragaman dan keseragaman fitoplankton dan zooplankton dapat dikategorikan sedang, berturut-turut sebesar 1,77–1,85 dan 1,70–1,77; 0,58–0,59 dan 0,77–0,79, sedangkan indeks dominansinya masuk dalam kategori rendah yaitu berturut-turut 0,27–0,28 dan 0,24–0,27. Analisis Principal Component Analysis (PCA) menunjukkan bahwa parameter oseanografi utama yang paling berpengaruh pada variasi komunitas plankton adalah turbiditas, klorofil-a, oksigen terlarut dan fosfat. Hasil uji T menunjukkan bahwa distribusi spasial kelimpahan fitoplankton dan zooplankton pada kedalaman 1 m dan 15 m berbeda nyata. Studi ini memberikan informasi penting tentang kelimpahan plankton dan faktor oseanografi yang berpengaruh di daerah penangkapan di Perairan Malang Selatan. Kata Kunci: komunitas plankton, parameter oseanografi, fishing ground, Perairan Malang Selatan AbstractThe South Malang water is a potential area as a fishing ground. The existence of various species of small pelagic fishes such as planktivores fishes are directly influenced by the growth of phytoplankton and zooplankton. Phytoplankton has an important role as the basis of the food chain in aquatic ecosystems, whereas zooplankton is its predator. The growth of phytoplankton and zooplankton is influenced by oceanography factors. This study aims to determine the variation of the plankton community and its relationship with oceanographic parameters, as well as the spatial distribution of plankton in the fishing ground at South Malang water. The purposive sampling method with zigzag technique at 10 sampling sites was used in data collection in this research. Sedwicgk rafter counting cells were used in plankton counting methods. The plankton samples were taken horizontally and vertically at depths of 1 and 15 m with a 20 μm planktonnet, while in situ oceanographic parameters were measured using aqua quality sensor AAQ type 1183 C. The results showed that phytoplankton abundance was 49.764 cells / m3, dominated by the genus Chaetoceros (Bacillariophyceae), and zooplankton abundance of 894 ind / m3, dominated by the genus Nauplius (Copepoda). The diversity index and uniformity index of phytoplankton and zooplankton could be categorized as the middle as 1.77-1.85 and 1.70-1.77; 0.58-0.59 and 0.77-0.79, respectively, while the dominance index was included in the low category that was 0.27-0.28 and 0.24-0,27, respectively. Principal Component Analysis (PCA) analysis showed that the most important major oceanographic parameters for plankton community variation were turbidity, chlorophyll-a, dissolved oxygen and phosphate. T test results show that the spatial distribution of phytoplankton abundance and zooplankton at depth of 1 m and 15 m are significantly different. This study provides important information on the plankton abundance and oceanography factors affected at fishing ground of South Malang water. Keywords: Plankton community, oceanography parameters, fishing ground, South Malang Water

Abstract

Mikroplastik merupakan bagian terkecil dari plastik yang berukuran 0,3 mm – >5 mm. Mikroplastik yang masuk ke lingkungan akan terakumulasi di perairan dan tidak mudah dihilangkan karena sifatnya yang persisten. Banyaknya kelimpahan mikroplastik sangat dipengaruhi oleh aktivitas dan sumber pencemarnya. Tujuan penelitian ini adalah untuk mengetahui kelimpahan dan jenis mikroplastik pada perairan di Banyuurip. Pengambilan sampel perairan dilakukan pada 5 lokasi yang memiliki aktivitas berbeda, yaitu tempat pelelangan ikan (TPI), mangrove, tambak, muara sungai, dan laut lepas. Pengambilan sampel perairan dilakukan sebanyak 3 kali pengulangan mengguakan plakton net dengan volume air tersaring sebanyak 15 L pada setiap stasiun. Idetifikasi mikroplastik menggunakan metode NOAA yang dibagi menjadi 4 tahapan, yaitu penyaringan sampel, pengeringan sampel, pemisahan zat organik dan identifikasi mikroplastik. Perbedaan kelimpahan jenis mikroplastik pada setiap lokasi dianalisis dengan mengukan ANOVA one way. Hasil kelimpahan total yang ditemukan sebesar 57,11 x 10² partikel/m³. Jenis mikroplastik yang ditemukan adalah fragment, fiber, dan film. Jenis mikroplastik yang paling banyak ditemukan pada perairan Banyuurip adalah jenis fragment. Hal ini dikarenakan sumber pencemaran mikroplastik jenis fragment lebih besar, yaitu berasal dari limbah rumah tangga dan kegiatan antropogenik. Kelimpahan jenis mikroplastik paling tinggi ditemukan pada mangrove sebesas 22,89 x 10² partikel/m³. Sementara itu, kelimpahan jenis mikroplastik pada lokasi tambak, muara sungai dan laut terbuka memiliki rentang nilai yang tidak jauh berbeda, yaitu 7,11– 8,89 x 10² partikel/m³. Hal ini diduga karena sampah lebih mudah terperangkap di akar-akar mangrove dan terakumulasi lebih banyak.

Abstract

Banyuurip is one of villages in Ujung Pangkah District, Gresik with high aquaculture activities of Perna viridis. Green mussels are highly produced in that area, however Banyuurip waters also has potential risk of heavy metals pollution. Therefore, this research was conducted to understand the concentrations of Fe and Zn in the sediments and in the Green Mussels. The heavy metals concentration will be used to analyze Bio Concentration Factor (BCF) and Human Health Risk Assessments (HHRA). A total about 45 P. viridis populations were collected from 3 sites in Banyuurip waters. In order to obtain a representative sample at each site, 15 populations of Green Mussels with similar shell lengths and bottom sediment were collected. Mussel’s tissue and bottom sediment were analyzed using AAS (AAnalyst700) to determine the concentrations of Fe and Zn. The concentrations of Fe were found almost similar with the concentrations of Zn in P. viridis within the range of Fe = 3.10 – 5.25 mg.kg-1 and Zn = 3.91 - 4.67 mg.kg-1. BCF (o-s) of Fe in P. viridis is lower than the BCF (o-s) of Zn, because the concentrations of Fe in the mussels were less than the concentrations in the sediments. According to the Target Hazard Quotients (THQ) values (THQ < 1), both heavy metals are not likely causing negative health effects for human during lifetime. However, Estimated Daily Intakes (EDI) values are above Provisional Tolerable Daily Intakes (PTDI) standard means it can cause negative effects due to daily consumption (EDI > PTDI).

Abstract

Sampah plastik merupakan sumber sekunder dari mikroplastik. Ukuran mikroplastik yang sangat kecil dapat menyerupai plankton dan mikroorganisme lainnya, sehingga berpotensi termakan oleh biota laut yang bersifat pasif seperti kerang. Mikroplastik yang terkandung dalam biota akan terakumulasi dan menyebabkan berbagai macam dampak. Penelitian ini dilakukan untuk menganalisa dan mengidentifikasi mikroplastik pada kerang Kijing (Pilsbryoconcha exilis) di Sungai Perancak, Bali. Analisa dan identifikasi dilakukan dengan 4 tahapan, yaitu preparasi sampel, perlakuan hidrogen peroksida, pemisahan massa jenis dan identifikasi mikroplastik secara visual. Hasil dari penelitian ini, ditemukan mikroplastik jenis fiber dan film pada sampel kerang. Mikroplastik jenis fiber paling banyak ditemukan pada sampel dibandingkan mikroplastik jenis film.Plastik waste is a secondary source of microplastics. The very small size of microplastics can resemble plankton and other microorganisms, so that they have the potential to be eaten by passive marine biota such as shellfish. Microplastics contained in biota will accumulate and cause various kinds of impacts. This research was conducted to analyze and identify microplastics in shellfish (Pilsbryoconcha exilis) in the Perancak River, Bali. Analysis and identification were carried out in 4 stages, namely sample preparation, hydrogen peroxide treatment, density separation and visual identification of microplastics. The results of this study, found microplastic types of fiber and film in the shell samples. Fiber type microplastics are mostly found in samples compared to film type microplastics.
