Abstract

The coastal region is the transitional area between the terrestrial and marine environment that has a great change of experiencing pressure due to pollution. This matter can caused by the strong population of Indonesia, quite high tourist activities, sea transportations, and large infra structure development. Marine debris in particular plastic is a big problem, not only in Indonesia, but also around the world. Hence, Indonesia is considered to be the second largest plastic waste producer in the world. Marine debris is part of a broader problem regarding waste management. Solid waste management has become a challenge for public health. In this research, garbage observation was done by adapting the shoreline survey method based on the national oceanic and atmospheric administration (NOAA, 2013). The results of observations of the research found that the type of macro-debris and meso-debris collected in the transect of observations were 228 items with a total weight of 2062.32 grams. Plastics debris were found in most quantities followed by rubbers, glasses and metals. The main factor for the abundance of marine debris in the coastal area of Tateli dua village Mandolang subdistrict Minahasa regency was the household waste, indicating that land-based sources provide a key factor for plastic pollution on the coastal area.

AbstrakWilayah pesisir yang merupakan sumber daya potensial di Indonesia, adalah daerah peralihan antara daratan dan lautan. Sumber daya ini sangat besar yang didukung oleh adanya garis pantai sepanjang sekitar 81.000 km. Garis pantai yang panjang ini menyimpan potensi kekayaan sumber alam yang besar.Potensi itu diantaranya potensi non hayati dan hayati. Disamping potensi sumberdaya alam yang tersebar luas di pesisir Indonesia, potensi pencemaran terhadap lingkungan pesisir dan laut pun memiliki peluang yang cukup besar.Peluang ini dapat disebabkan oleh padatnya penduduk Indonesia, aktivitas wisata yang cukup tinggi termasuk transportasi, dan pembangunan yang besar.Sampah laut khususnya plastik merupakan masalah besar, bukan hanya di Indonesia, tetapi di seluruh dunia.Indonesia juga dianggap sebagai produsen sampah plastik ke laut terbesar kedua di dunia.Sampah laut merupakan bagian dari masalah yang lebih luas terkait pengelolaan sampah.Pengelolaan sampah padat telah menjadi tantangan kesehatan masyarakat.Pengamatan sampah dilakukan dengan adaptasi metode shoreline survey methodology berdasarkan National Oceanic and Atmospheric Administration(NOAA, 2013). Hasil pengamatan di lokasi penelitian di temukan jenis sampah makro-debris dan meso-debris yang dikumpulkan pada transek pengamatan sebanyak228 item dengan bobot total 2062,32 gram. Hasil penelitian menunjukkan bahwa plastik debris ditemukan dalam jumlah terbanyak diikuti oleh karet, kaca dan logam. Faktor utama penyebab kelimpahan sampah laut di Pantai Tumpaan Desa Tateli Dua, Kecamatan Mandolang, Kabupaten Minahasa adalah sampah aktivitas penduduk yang menunjukkan bahwa sumber-sumber berbasis lahan menyediakan input utama untuk polusi plastik di pantai tersebut.

Abstract

The long-term goal of this research is the management of vaname shrimp culture that is certified "Good Fish Cultivation" (GFC) based on environmentally friendly and sustainable technology so that its products can be accepted in domestic and foreign markets. The specific target is the implementation of phytoremediation technology in shrimp aquaculture at the Marine Field Station owned by FPIK UNSRAT which will be developed into the North Sulawesi Marine Education Center (NSMEC) area. The long-term goals and specific targets above will support the leading areas of maritime and maritime affairs in the Unsrat Research Master Plan. Analysis of water quality parameters and shrimp growth response using controlled-scale phytoremediation technology was carried out to see the remediation ability of Eucheuma denticulatum seaweed. Research method using phytoremediation technology application on white shrimp cultivation in the form of demonstration plots. The average growth in the plots provided with seaweed ranged from 8.3 g to 8.4 g. While the control that was not stocked with seaweed, the average weight growth was 6.6 g. This figure shows quite different values for different treatments. Water quality parameters such as DO, pH showed better water quality conditions in the plots spread with seaweed. This shows that Eucheuma denticulatum seaweed is capable of being a phytoremediator for the environment where the vannamei shrimp (Litopenaeus vannamei) is present. Seaweed Eucheuma denticulatum has the ability to absorb waste such as the faces of white shrimp (Litopenaeus vannamei). Keywords: phytoremediation, seaweed, vaname shrimp, East Likupang.

Abstract

Threats to the marine and coastal environment are increasing due to the increasing population and increasing exploitation of the population on the coast. If the garbage is thrown into the river or thrown directly into the sea, it will eventually result in a reduction in the beauty of the coastal area, the sea and the mangrove ecosystem. Inorganic waste with the type of plastic will not be separated from everyday life, due to the increasing number of people in the world. Therefore, the demand for and consumption of plastic-type materials is increasing and will continuously enter the land environment to the sea. Sampling is located at Tasik Ria Beach, Tombariri District, Minahasa Regency. The sampling time for marine debris in the mangrove ecosystem will be in August 2021. Inorganic waste sampling is carried out in the mangrove ecosystem by looking at the age of the month at the lowest low tide. Sampling used the line transect method or quadrant line transect and was carried out directly in the morning and it took one day until the tide started. Based on the research objectives, to identify inorganic marine debris found in the mangrove ecosystem of the Tasik Ria beach and analyze the total density of inorganic marine debris, both heavy and the amount laid on the mangrove ecosystem, research conducted at Tasik Ria Beach, Tombariri District, Minahasa Regency has obtained five types of waste. namely plastic, glass, metal, rubber and wood waste and their derivatives. Keywords: Coastal, Mangrove Ecosystem, Identification, Marine Debris, Tasik Ria Coast
