Abstract

Fisheries activity in Lampung Bay which has been very active in recent years is the cultivation of green mussels (P. viridis) for consumption. Located in Teluk Betung Timur sub-district, this is considered appropriate because of the environmental parameters that support the life of P. viridis. The location of P. viridis cultivation is not far from coastal settlements (±500-600 m from settlements). Anthropogenic activities of coastal residents as well as the use of plastic materials in the cultivation are concerned to be the source of microplastic contamination that found in P. viridis. This study aims to determine the presence and characteristics of microplastics in P. viridis as well as to compare the abundance of microplastics in the gills and digestive organs. Taking 30 P. viridis by purposive sampling with homogeneous size. The samples were analyzed by microplastics in chemical oceanography and biology micro Laboratory, FPIK, IPB University. P. viridis tissue was destructed by using 10% KOH solution at a ratio of 1:3 (m/v) at 60 °C for 24 hours and then filtered using a 1.6 µm Whatman GF/A filter paper. Abundance of microplastics in whole soft tissue were 0.53±0.7 mgl/g. The gill organs were found to be more microplastic than the digestive organs (p<0.05). The fragments microplastic is most commonly found in intact tissues and digestive organs, while fiber is mostly found in the gills of P. viridis. Blue color and size <100 µm were most commonly found in intact tissues, gills and digestive organs of P. viridis.  Kegiatan perikanan di Teluk Lampung yang sangat aktif dalam beberapa tahun ini yaitu kultivasi kerang hijau (P. viridis) konsumsi. Berlokasi di kecamatan Teluk Betung Timur, hal ini dinilai tepat karena parameter lingkungan yang menunjang kehidupan P. viridis. Lokasi pembesaran P. viridis tidak jauh dari pemukiman penduduk pesisir (±500-600 m dari pemukiman). Kegiatan antropogenik penduduk pesisir juga penggunaan material plastik pada sistem pembesaran dikhawatirkan dapat menjadi sumber cemaran mikroplastik yang terdapat pada P. viridis. Penelitian ini bertujuan untuk mengetahui keberadaan dan karakteristik mikroplastik pada P. viridis juga membandingkan kelimpahan mikroplastik pada insang dan organ pencernaan. Pengambilan 30 P. viridis secara purposive sampling dengan ukuran homogen. Analisis mikroplastik dilakukan di laboratorium oseanografi kimia dan biologi mikro, FPIK, Universitas Pertanian Bogor. Destruksi jaringan P. viridis dengan menggunakan larutan KOH 10% perbandingan 1:3 (m/v) pada suhu 60 °C selama 24 jam lalu difiltrasi menggunakan filter paper whatman GF/A 1,6 µm. Mikroplastik tubuh kerang utuh yaitu 0,53±0,7 mgl/g. Organ insang lebih banyak ditemukan mikroplastik dibandingkan organ pencernaan (p<0,05). Bentuk fragmen paling banyak ditemukan di jaringan utuh dan organ pencernaan, sedangkan fiber banyak ditemukan di insang P. viridis. Warna biru dan ukuran <100 µm paling banyak ditemukan di jaringan utuh, insang maupun organ pencernaan P. viridis.

Abstract

Based on data from the OECD's Global Plastic Outlook (2022), marine debris in the world has reached 350 million tons, which dominates plastic waste. Indonesia is the second country after Tingkok which produces the most marine debris. Based on the results of the National Waste Management Information System data from the Ministry of Environment and Forestry (Ministry of Environment and Forestry) it shows that Indonesia produces 34.85 million tonnes of landfilled waste. Of the total, 12.13 million tonnes of waste per year is not managed in 2022. The President of the Republic of Indonesia, Mr. Joko Widodo, is very concerned and committed to the waste problem and has a target to reduce marine plastic waste by 70% by 2025 in order to achieve the target set by the President of the Republic of Indonesia. Therefore, research on marine debris in coastal areas and small islands in Indonesia is very important information to research. This research was conducted in Wangi-Wangi Waters, Wakatobi Regency on 12-15 September 2023. The aim was to determine the type, abundance and weight of marine debris and its relationship with coral cover in Wangi-Wangi Waters. The marine debris sampling method is based on two characteristics, namely the intertidal zone (sandy beach) using the shoreline survey methodology and the subtidal zone (coral reef ecosystem) using the Belt Transect method (KLHK, 2020). ). Marine debris macro criteria range from (>2.5 cm - <1 m) Based on research results, the dominant abundance of macro marine debris was found to be 187 items/m2 of plastic, followed by wood and its derivatives 162 items/m2, glass 17 items/m2, cloth and its derivatives 12 items/m2 , fiber 12 items/m2, and rubber 8 items/m2. The total weight of macro marine debris in the intertidal zone is 574.10 grams/m2 and the subtidal zone is 178.7 grams/m2. Data on live coral cover ranges from 54.33% to 73.07%, good criteria. The relationship between the abundance of macro marine debris and coral cover has an inverse relationship, the higher the live coral cover, the lower the abundance of macro marine debris in that area. Berdasarkan data OECD’s Global Plastic Outlook (2022) marine debris di dunia telah mencapai sebesar 350 juta ton yang mendominasi sampah plastik. Indonesia menjadi negara peringkat kedua setelah tingkok penghasil marine debris terbanyak. Berdasrakan hasil data sistem informasi pengelolaan sampah Nasional dari KLHK (Kementrian Lingkungan Hidup dan Kehutanan) menunjukan bahwa Indonesia  mengahsilkan 34.85 juta ton timbunan sampah dari total tersebut 12.13 juta tonsampah per tahun sampah tidak di kelola pada tahun (2022). Presiden RI Bapak Joko widodo sangat konsen dan berkomitmen dengan permasalahan sampah dan memiliki target untuk menurunkan sampah plastik laut sebanyak 70% pada tahun 2025 dalam rangka mencapai target yang telah ditetapkan oleh presiden RI. Oleh karena itu maka penelitian marine debris di wilayah pesisir dan pulau-pulau kecil Indonesia merupakan suatu informasi sangat penting untuk diteliti. Penelitian ini dilakukan di Perairan Wangi-Wangi, Kabupaten Wakatobi pada 12-15 September 2023. Bertujuan untuk mengetahui jenis, kelimpahan,dan berat marine debris serta hubungannya dengan tutupan terumbu karang di Perairan Wangi-Wangi. Metode pengambilan sampel marine debris berdasarkan dua karakteristik yaitu zona intertidal (pantai berpasir) menggunakan metode survei garis pantai (shoreline survey methodology)dan zona subtidal (ekosistem terumbu karang) menggunakan metode Belt Transect atau transek sabuk (KLHK, 2020. Kriteria makro marine debris berkisar (>2.5 cm - <1.0 m)  Berdasarkan hasil penelitian kelimpahan macro marine debris yang dominan ditemukan yaitu jenis plastik sebanyak 187 item/m2, diikuti kayu dan turunannya 162 item/m2, kaca 17 item/m2, kain dan turunannya 12 item/m2, fiber 12 item/m2, dan karet 8 item/m2. Berat total macro marine debris pada zona intertidal sebesar 574.10 gram/m2 dan zona subtidal sebesar 178.7 gram/m2. Data tutupan karang hidup berkisar 54.33%-7307% kriteria baik. Hubungan kelimpahan macro marine debris dengan tutupan karang memliki hubungan yang berbanding terbalik, semakin tinggi tutupan karang hidup maka semakin rendah maka kelimpahan macro marine debris pada area tersebut.

Abstract

Mangroves are the dominant ecosystem in coastal areas and estuaries and one of the most productive ecosystems in the world. Mangroves are an essential component in a complex food chain and have the potential for the life of various marine and terrestrial biotas, microorganisms, and macroorganisms. The decomposition of mangrove leaf litter by fungal bacteria produces nutrient source that is beneficial for fish, shrimps, and crabs. This study discusses the production and decomposition rate of mangrove leaf litter in the mangrove ecosystem of Muara Pagatan, South Kalimantan. With transect and litter trap methods, litter production during the observation ranged from 218.51 - 858.28 g/m2/45day. Of the four types of mangroves found, the highest litter production was found in Rhizophora mucronata mangrove species at 858.28 g/m2/45day, followed by Bruguiera gymnorrhiza species at 268.52 g/m2/45day, and the lowest litter production was Avicennia marina mangrove species at 222.9 g/m2/45day and Sonneratia alba at 218.51 g/m2/45day. The remaining dry weight during observation ranged from 1.06 g - 2.46 g. In sum, the highest litter productivition and decomposition rate was found in Rhizophora species and litter was not completely decomposed after 45 days.

Abstract

Monitoring and assessing the items stranded on shorelines is a crucial step in addressing the threat posed by marine debris to our ocean. The objective of this study is to examine the occurrence and categorize marine debris that accumulates on the beach and mangrove area of Pulau Rambut Wildlife Reserve from the transitional season 2 to the rainy season. The abundance of marine debris is significant in transitional season 2. There is no significant difference between different seasons. The dominant form of debris among all macrodebris categories during transitional season 2 was plastic, accounting for 46.38% of the total. Single-use plastics like styrofoam, shoes, sandals, gloves, plastic wrap, and plastic sachets were found to be the most common types of large-scale plastic debris, comprising 60% of total macroplastic debris. The debris found on Rambut Island is believed to originate from debris carried by rivers that flow into Jakarta Bay. The presence of seasonal winds, currents, waves, and tides further contribute to the accumulation of debris in this area.
