Abstract

Mangrove ecosystem is a place where all pollutants come from which carry various kinds of pollutants originating from the mainland. The sea is also a direct disposal site by human or industrial activities in an easy way, as we know that there is organic and inorganic waste. The purpose of this research is to identify the type of inorganic waste and calculate the amount of inorganic waste density in the mangrove ecosystem of Talawaan Bajo Village. The method used in this study is the transect line. The results showed that the dominant inorganic waste in the mangrove ecosystem of Talawaan Bajo Village was predominantly plastic waste with a total of 132 pot/900m2 (1.466 Pot/Ha) with a weight of 3131, 55gram/900m2 (34.795 g/ha). The results of this study will be a recommendation for the local government to make an appeal and socialization about the dangers of inorganic waste to the life of the ecosystem in the sea and education about the management of inorganic waste especially plastic types to the public properly. Keywords: Mangrove, Inorganic Waste, Talawaan Bajo  AbstrakEkosistem mangrove merupakan tempat bermuaranya seluruh bahan pencemar yang membawa berbagai macam bahan pencemar yang berasal dari daratan.

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

During rainy season, a various type of litter can enter the ocean through rivers. This is a significant contributor to the amount of marine litter in the waters. In order to access the type, composition, and density of the litter during rainy season, this study was conducted in Manado Bay, North Sulawesi. The observation was done on the litter stranded on the beach, and they were classified into two different size groups, macro (>2,5 cm)- and meso (0,5-2,5 cm)-sizes. Malalayang Beach and Bailang Beach were chosen for the location of the study. Litter type, composition, and density was evaluated according to National Marine Litter Monitoring Guide. The result showed that there were 7 types of macro-size and 6 types of meso-size marine litter in Malalayang Beach and it was dominated by glass and ceramic for both sizes. In Bailang Beach, 9 types of macro-size and 7 of meso-size were found, and it was dominated by plastics. It can be concluded that various type of marine litter present in Manado Bay, both macro- and meso- sizes, during the rainy season. The highest composition was the glass and ceramics type. However, the highest density was the plastic type.---Pada musim hujan, berbagai jenis sampah dari daratan masuk ke perairan pantai melalui sungai. Hal ini merupakan penyumbang signifikan bagi jumlah sampah laut di perairan. Untuk menilai jenis bahan, komposisi, dan kepadatan sampah laut pada musim hujan, penelitian ini dilakukan di Teluk Manado, Sulawesi Bagian Utara. Pengamatan dilakukan terhadap sampah laut yang terdampar di pantai (beach litter), berukuran makro (> 2,5 cm) dan meso (0,5-2,5 cm), di dua lokasi, yaitu Pantai Malalayang dan Pantai Bailang. Sampah laut dievaluasi menggunakan Pedoman Nasional tentang Pemantauan Sampah Pantai. Hasil penelitian menunjukkan, sampah laut jenis plastik, kaca & keramik, busa plastik, kertas & kardus, logam, karet, kayu, kain, dan bahan lainnya, baik berukuran makro maupun meso ditemukan di perairan. Di Pantai Bailang, komposisi sampah laut berukuran makro dan meso didominasi oleh jenis bahan plastik; tetapi, di Pantai Malalayang didominasi oleh jenis kaca & keramik. Demikian juga untuk kepadatan sampah laut di Pantai Bailang, jenis bahan plastik mendominasi, baik sampah berukuran makro maupun meso. Sedangkan di Pantai Malalayang, jenis kaca & keramik mendominasi kepadatan sampah laut pada semua ukuran. Selanjutnya, dapat disimpulkan, pada musim hujan, berbagai jenis bahan sampah laut berada di Teluk Manado, baik berukuran makro maupun meso. Komposisi terbesar untuk ukuran makro dan meso ialah jenis bahan kaca & keramik. Namun, kepadatan tertinggi untuk ukuran makro dan meso ialah sampah jenis bahan plastik.

Abstract

Microalgae are organisms that contain chlorophyll and other pigments so they can carry out photosynthesis. Microalgae are widespread in nature and can be found in any environment exposed to sunlight. Microalgae are micro-sized biota with a diameter of less than 2 µm. The benefits of microalgae for other living things, especially humans, are numerous, including as a source of food and ingredients in the manufacture of medicines. Dunaliella sp. is a group of green algae that contains protein, fat and carbohydrates as a good source of food. Growth rate and density of microalgae Dunaliella sp. and the effect of lead acetate with different concentrations was observed using a microscope, starting from the lag phase, the logarithmic phase, the stationary phase and the declination phase. Dunaliella sp. Experiencing an exponential phase in the observation before treatment, namely on the 9th day and then doing the treatment. Treatment with lead acetate with concentrations of 10 ppm, 50 ppm and 80 ppm is very influential in the growth of microalgae. The result is that lead acetate contains toxins that can kill microalgae cells in both low and high concentrations.Keywords: Microalgae, Dunaliella sp., Lead Acetate, Concentration

Abstract

Hard coral is one of the main components of this forming coral reef ecosystem. Bulutui waters have coral reef ecosystems that have a direct role as a source of livelihood for people around these waters. However, there are non-environmentally friendly human activities such as fishing using explosives or chemical solutions that cause coral reef damage. The aimed of this research was to find out the condition of hard coral’s percentage cover and to described the frequency of hard coral’s occurance therefore it’s could be representative data at this location. Coral data was collected by using PIT (Point Intercept Transect) method. The value of percentage cover of hard corals at Bulutui waters are 20.58% and the value is categorized damaged. The total frequency of hard coral’s occurance at station 1 are 66 and dominated by Coral Submassive (CS), at station 2 are 23 and dominated by Coral Massive (CM), at station 3 are 18 and dominated by Coral Foliose (CF) and then at station 4 are 140 and dominated by Coral Foliose (CF).Keywords: Percentage Cover, Scleractinia Coral, Bulutui Waters, PIT Methods.
