Abstract

This research was conducted in Bulutui Village, West Likupang District, related to theproblems raised how is the solubility of Dissolved Oxygen (DO) and the pH of sediment-insertedwater at mangrove locations, and on the coast, then this research aims to find out how the solubility ofoxygen (DO), and acidity (pH) of sediment-inserted water in mangrove ecosystems and on the coastin Bulutui Village, West Likupang District. Based on the results of measurements that have beencarried out in Bulutui Village, West Likupang District, it was found that the value of the dissolvedoxygen content at the mangrove location was in the range of 0.36 – 1.98 ppm, with an average of0.98 ppm, the pH value ranged from 6.16 – 6.89 with an average value of 6.04. In coastal locations,the dissolved oxygen content ranges from 1.26 to 2.87 ppm, with an average of 2.09 ppm, the pHvalue ranges from 6.78 to 8.90, with an average value of 8.34. The statistical t test showed that therewas a difference between the dissolved oxygen values in the sedimentary water in the mangrovesand the coast, as well as the acidity (pH).

Berdasarkan hasilpengukuran yang telah dilakukan di Desa Bulutui Kecamatan Likupang Barat ditemukan nilai darikandungan oksigen terlarut pada lokasi mangrove adalah berkisar 0,36 – 1,98 ppm, dengan rataratanya 0,98 ppm, nilai pH berkisar 6,16 – 6,89 dengan nilai rata rata 6,04. Pada Lokasi pesisirdengan kandungan oksigen terlarut berkisar 1,26 – 2,87 ppm, dengan rata rata 2,09 ppm nilai pHberkisar 6,78 – 8,90, dengan nilai rata – rata 8,34. Uji statistika t test menunjukkan adanyaperbedaan antara nilai oksigen terlarut pada air sisipan sedimen di mangrove, dan pesisir, demikianjuga keasaman (pH).

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 ABSTRAK Ancaman terhadap lingkungan laut dan pesisir semakin meningkat diakibatkan oleh bertambahnya jumlah penduduk dan bertambah pula eksploitasi penduduk di pesisir. Apabilah sampah tersebut dibuang ke sungai maupun dibuang langsung ke laut yang akhirnya berakibat berkurangnya keindahan wilayah pesisir, laut maupun pada ekosistem mangrove. Sampah anorganik dengan jenis plastik tidak akan terlepas dengan kehidupan sehari-hari, dikarenakan bertambahnya jumlah penduduk di dunia. Maka dari itu permintaan maupun kunsumsi bahan dengan berjenis plastik semakin meningkat dan akan secara terus-menerus masuk ke lingkungan daratan sampai ke laut. Pengambilan sampel terletak di Pantai Tasik Ria Kecamatan Tombariri Kabupaten Minahasa. Waktu pengambilan sampel sampah laut pada ekosistem mangrove dilaksanakan pada bulan Agustus 2021. Pengambilan sampel sampah anorganik di lakukan pada ekosistem mangrove dengan melihat umur bulan pada saat kondisi surut terendah. Pengambilan sampel menggunakan metode line transek atau transek garis kuadran dan dilakukan secara langsung di pagi hari dengan membutuhkan waktu selama satu hari sampai pada saat air mulai pasang. Berdasarkan tujuan penelitian mengidentifikasi sampah laut anorganik yang terdapat di ekosistem mangrove pantai tasik ria dan menganalisa jumlah kepadatan sampah laut anorganik baik itu berat maupun jumlah yang tergampar pada ekosistem mangrove penelitian yang di lakukan di Pantai Tasik Ria Kecamatan Tombariri Kabupaten Minahasa telah di dapatkan lima jenis sampah yaitu sampah jenis plastik, kaca, logam, karet serta kayu dan turunannya.

Abstract

Manado shore is one of the water areas in North Sulawesi that has potential in coastal tourism. This is proved through the presence of tourists who want to enjoy the underwater beauty by diving either by snorkeling or by scuba. This study aimed to determine the density and composition of seabed waste in the waters of Manado shore. Sampling was carried out at 2 stations, the first station was in the estuary area of the Malalayang River and the second station was in the waters of the Megamas Manado area. The sampling method was carried out using the belt transect method by conducting SCUBA dives with a sampling area of 100 meters long and 2 meters wide. The identification results obtained 7 types of macro-sized marine debris which were classified into 17 types, while meso- sized garbage found 6 types of marine debris which were classified into 11 types. The composition for macro-sized waste is dominated by the type of plastic material (PL code; composition of 31%; weight of 7,990.025 g) while up to meso is dominated by the type of glass & ceramic material, (GC; 39%; 120.5 g). Macro and meso size marine debris density at the Manado Beach location, for macro size is dominated by the type of plastic material (PL code; 1.9 items/m2), while the meso size is dominated by the type of plastic material (PL; 1.42 items/m2). m2). Keywords: Meso Trash Composition, Density, Seabed ABSTRAK Pantai Manado merupakan salah satu wilayah perairan yang ada di Sulawesi Utara yang memiliki potensi dalam kepariwisataan pantai. Hal ini dibuktikan dengan hadirnya para wisatawan yang ingin menikmati keindahan bawah laut dengan menyelam baik dengan snorkeling maupun dengan SCUBA. Tujuan penelitian ini untuk mengetahui jumlah kepadatan dan komposisi sampah dasar laut di perairan Pantai Manado. Pengambilan sampel dilakukan pada 2 stasiun, stasiun yang pertama berada pada daerah estuari muara Sungai Malalayang dan stasiun kedua berada pada daerah perairan kawasan Megamas Manado. Metode pengambilan sampel dilakukan dengan metode belt transek dengan cara melakukan penyelaman SCUBA dengan luasan pengambilan sampel panjang 100 meter dan lebar 2 meter. Hasil identifikasi didapatkan 7 jenis sampah laut berukuran makro yang diklasifikasi kedalam 17 jenis, sedangkan sampah berukuran meso ditemukan 6 jenis sampah laut yang diklasifikasi kedalam 11 jenis. Komposisi untuk sampah ukuran makro didominasi jenis bahan plastik (kode PL; komposisi sebesar 31 %; berat sebesar 7.990,025 g) sedangkan sampai meso didominasi jenis bahan kaca & keramik, (GC; 39 %; 120,5 g). Kepadatan sampah laut ukuran makro dan meso di lokasi Pantai Manado, untuk ukuran makro didominasi oleh jenis bahan plastik (kode PL; sebanyak 1,9 item/m2), sedangkan ukuran meso didominasi oleh jenis bahan plastik (PL; sebanyak 1,42 item/m2).
