Abstract

Marine debris is all material in the solids form that could not be found naturally (is a product of human activities) in the territorial waters (oceans, beaches) and could threat directly to the conditions and productivity of the territorial waters. Marine debris is defined by UNEP (2009) as solid material that is difficult to decompose, plant or processed results are discarded or left in marine and coastal environments. Marine debris consists of goods used by humans and deliberately disposed to the sea. Marine debris can be transported with ocean currents and winds from one place to another, even being able to travel long distances from the source. Common waste problems encountered in urban areas in Southeast Asian countries, as populations grew, followed by increased revenues potential garbage and various types of garbage produced. Marine debris classified as Meso and Macro trash with size > 5 mm to 1 m. Marine debris observation is carried out by modifying the method of coastline survey methods based on National Oceanic and Atmospheric Administration (2013). There are some important things to be prepared before doing the observation that was stranded in coastal areas such as the selection of observation locations, materials needed for observation and time observation. Based on the results of the research of marine debris samples obtained at the research site there are 2 characteristics of marine debris namely of macro flakes collected in twelve transect as much as 341 grains, while meso-debris contains as many as 94 goods. Also the debris with a category of micro-debris as many as 46 items with a total of 481 items and total weight total 1433.38 gr/m2.Keywords: Marine debris, Tongkaina, Talawaan Bajo Sampah laut atau marine debris adalah semua material berbentuk padatan yang tidak dijumpai secara alami (merupakan produk kegiatan manusia) di wilayah perairan (lautan, pantai) dan dapat memberikan ancaman secara langsung terhadap kondisi dan produktivitas wilayah perairan. Sampah laut, didefiniskan oleh UNEP (2009) sebagai bahan padat yang sulit terurai, hasil pabrik atau olahan yang dibuang atau dibiarkan di lingkungan laut dan pesisir. Sampah lautan dapat ditransport oleh arus laut dan angin dari satu tempat ke tempat lainnya, bahkan dapat menempuh jarak yang sangat jauh dari sumbernya. Permasalahan sampah umum dihadapi pada daerah perkotaan di negara Asia Tenggara, seiring meningkatnya jumlah penduduk, diikuti peningkatan pendapatan, sehingga mengakibatkan meningkatnya potensi timbulan sampah perkapita dan beragamnya jenis sampah yang dihasilkan (Nguyen & Schnitzer, 2009). Sampah laut ditelaah adalah yang tergolong sampah meso dan makro dengan ukuran > 5 mm sampai 1 m. Pengamatan sampah dilakukan dengan modifikasi metode shoreline survey methodology berdasarkan National Oceanic and Atmospheric Administration NOAA (2013). Ada beberapa hal yang penting untuk disiapkan sebelum melakukan pengamatan sampah yang terdampar di daerah pantai seperti pemilihan lokasi pengamatan, bahan yang di perlukan untuk pengamatan dan waktu pengamatan. Berdasarkan Hasil Penelitian sampel sampah laut yang diperoleh di lokasi penelitian terdapat 2 karakteristik sampah laut yaitu makro-debris yang dikumpulkan pada dua belas transek sebanyak 341 item, sedangkan meso-debris terdapat sebanyak 94 item, serta ditemukan juga sampah dengan kategori mikro-debris sebanyak 46 item dengan total keseluruhan 481 item dan berat total keseluruhan 1433,38 gr/m2. Kata Kunci: Sampah laut, Tongkaina, Talawaan Bajo

Abstract

Grapsus sp crab has a greenish black body color and also known as stone crab. Crabs in the genus Grapsus sp have a swift movement, long legs, they do not have swimming legs and have small reddish purple or purple-orange color, claws on the body of this crab indicated the presence of pigments such as carotenoid pigments. Carotenoid pigments are one form of secondary metabolites which consist of carotene and xanthophyll groups. Carotenoid pigments are present in yellow, orange or orange red which are also found in crabs. Separation of carotenoid pigments can be done using the TLC method, High Performance Liquid Chromatography (HPLC) and Column Chromatography (CC). The purpose of this study was to determine the type of carotenoid pigment from male Grapsus sp crab extract using the Column Chromatography separation method. From the results of this study, the carotenoid pigment content in the 1,2 and 3 carapace was 46,85 μg, 39 µg, and 33,14 µg. The carotenoid pigment concentrations in carapace extracts 1,2 and 3 are 25,38 µg/g, 23,4 µg/g and 5,11 µg/g. From the results of the separation using the column chromatography method, the type of carotenoid pigment identified from the carapace extract of Grapsus sp male is β-Carotene, Ekinenon, Astaxantine, Kantaxantine and Astacen.Keywords: Grapsus sp, Carotenoid, Column ChromatographyKepiting Grapsus sp memiliki warna tubuh hitam kehijauan dan dikenal dengan nama kepiting batu. Kepiting dalam genus Grapsus sp memiliki gerakkan yang cekatan, mempunyai kaki yang panjang, tidak memiliki kaki renang dan memiliki capit berukuran kecil yang berwarna ungu kemerahan atau ungu-oranye warna pada tubuh kepiting ini mengindikasikan adanya kandungan pigmen seperti pigmen karotenoid. Pigmen karotenoid merupakan salah satu bentuk metabolit sekunder yang yang terdiri dari golongan karoten dan xantofil. Pigmen karotenoid  hadir dalam warna kuning, oranye, atau merah oranye, yang juga ditemukan pada kepiting. Pemisahan pigmen karotenoid dapat dilakukan dengan menggunakan metode KLT, Kromatografi Cair Kinerja Tinggi (KCKT) dan Kromatografi Kolom (KK). Tujuan dari penelitian ini adalah untuk mengetahui jenis pigmen karotenoid dari ekstrak kepiting Grapsus sp Jantan dengan menggunakan metode pemisahan Kromatografi Kolom. Dari hasil penelitian ini, didapatkan kandungan pigmen karotenoid pada karapas 1,2 dan 3 adalah 46,85 µg 39 µg, dan 33,14 µg. Konsentrasi pigmen karotenoid pada ekstrak karapas 1,2 dan 3 adalah 25,38 µg/g, 23,4 µg/g dan 5,11 µg/g. Hasil pemisahan menggunakan metode pemisahan kromatografi kolom didapatkan ekstrak karapas kepiting Grapsus sp jantan memiliki jenis pigmen β-Karoten, Ekinenon, Astaxantin, Kantaxantin dan Astasen.Kata kunci: Grapsus sp, Karotenoid, Kromatografi Kolom,

Abstract

Based on the material content, waste is grouped into two types, namely organic waste (waste derived from animal, plant and human parts) and inorganic waste (waste derived from materials such as metal, glass, styrofoam, plastic and rubber). Inorganic waste is one of the coastal pollution problems, yet information about inorganic waste in mangrove ecosystem was relatively low, especially at Lesah Village, Tagulandang Sub district, Sitaro Regency. This study aims to determine the distribution of inorganic waste by type and to analyze the characteristic of inorganic waste based on the amount of size and weight found. The method used in this research is the line transects method at 3 different stations. The results showed that the types of marine debris that found were plastic, rubber, metal, and glass waste and there were 2 characteristics, namely mega-debris and macro-debris. Of the various types of debris obtained, plastic is the most commonly found, 161 items/23.329m2 (69.099 Items/ha) with a total weight of 1357.75 gram/ha and a total size of 1938.93 cm/ha. Followed by rubber debris as many as 5 items/23.329m2 (2.146 items/ha) with a total weight of 159.309 gram/ha and a total size of 59.871 cm/ha. Then, glass debris as many as 4 items/23.329m2 (1.717 items/ha) with a total weight of 402,159 grams/ha a total size of 31.030 cm/ha. Whereas, metal debris is the lowest value found as many as 3 item/23.329m2 (1.288 items/ha) with a total weight of 67.622 gram/ha and a total size of 19.528 cm/ha.Keywords: Inorganic waste, Mangrove Ecosystem, Desa Lesah
