Abstract

AbstractPerairan Malang Selatan merupakan daerah yang potensial sebagai daerah penangkapan ikan. Keberadaan berbagai jenis ikan pelagis kecil terutama ikan planktivor secara langsung dipengaruhi oleh pertumbuhan fitoplankton dan zooplankton. Fitoplankton mempunyai peran penting sebagai dasar rantai makanan dalam ekosistem perairan, sedangkan zooplankton merupakan herbivor pemangsanya. Pertumbuhan fitoplankton dan zooplankton dipengaruhi oleh faktor oseanografinya. Penelitian ini bertujuan untuk mengetahui variasi komunitas plankton dan hubungannya dengan parameter oseanografinya, serta distribusi spasial plankton di daerah penangkapan ikan di Perairan Malang Selatan, Jawa Timur. Metode purposive sampling dengan teknik zigzag pada 10 titik sampling digunakan dalam pengambilan data pada penelitian ini. Sedwicgk rafter counting cell digunakan dalam metode penghitungan plankton. Sampel plankton diambil secara horizontal dan vertikal pada kedalaman 1 dan 15 m dengan jaring plankton bermata jaring 20 µm, sedangkan parameter oseanografi secara in situ diukur menggunakan aqua quality sensor tipe AAQ 1183 C. Hasil penelitian menunjukkan bahwa kelimpahan fitoplankton sebesar 49.764 sel/m3, didominasi oleh genus Chaetoceros. (Bacillariophyceae), dan kelimpahan zooplankton sebesar 894 ind/m3, didominasi oleh genus Nauplius. (Copepoda). Indeks keanekaragaman dan keseragaman fitoplankton dan zooplankton dapat dikategorikan sedang, berturut-turut sebesar 1,77–1,85 dan 1,70–1,77; 0,58–0,59 dan 0,77–0,79, sedangkan indeks dominansinya masuk dalam kategori rendah yaitu berturut-turut 0,27–0,28 dan 0,24–0,27. Analisis Principal Component Analysis (PCA) menunjukkan bahwa parameter oseanografi utama yang paling berpengaruh pada variasi komunitas plankton adalah turbiditas, klorofil-a, oksigen terlarut dan fosfat. Hasil uji T menunjukkan bahwa distribusi spasial kelimpahan fitoplankton dan zooplankton pada kedalaman 1 m dan 15 m berbeda nyata. Studi ini memberikan informasi penting tentang kelimpahan plankton dan faktor oseanografi yang berpengaruh di daerah penangkapan di Perairan Malang Selatan. Kata Kunci: komunitas plankton, parameter oseanografi, fishing ground, Perairan Malang Selatan AbstractThe South Malang water is a potential area as a fishing ground. The existence of various species of small pelagic fishes such as planktivores fishes are directly influenced by the growth of phytoplankton and zooplankton. Phytoplankton has an important role as the basis of the food chain in aquatic ecosystems, whereas zooplankton is its predator. The growth of phytoplankton and zooplankton is influenced by oceanography factors. This study aims to determine the variation of the plankton community and its relationship with oceanographic parameters, as well as the spatial distribution of plankton in the fishing ground at South Malang water. The purposive sampling method with zigzag technique at 10 sampling sites was used in data collection in this research. Sedwicgk rafter counting cells were used in plankton counting methods. The plankton samples were taken horizontally and vertically at depths of 1 and 15 m with a 20 μm planktonnet, while in situ oceanographic parameters were measured using aqua quality sensor AAQ type 1183 C. The results showed that phytoplankton abundance was 49.764 cells / m3, dominated by the genus Chaetoceros (Bacillariophyceae), and zooplankton abundance of 894 ind / m3, dominated by the genus Nauplius (Copepoda). The diversity index and uniformity index of phytoplankton and zooplankton could be categorized as the middle as 1.77-1.85 and 1.70-1.77; 0.58-0.59 and 0.77-0.79, respectively, while the dominance index was included in the low category that was 0.27-0.28 and 0.24-0,27, respectively. Principal Component Analysis (PCA) analysis showed that the most important major oceanographic parameters for plankton community variation were turbidity, chlorophyll-a, dissolved oxygen and phosphate. T test results show that the spatial distribution of phytoplankton abundance and zooplankton at depth of 1 m and 15 m are significantly different. This study provides important information on the plankton abundance and oceanography factors affected at fishing ground of South Malang water. Keywords: Plankton community, oceanography parameters, fishing ground, South Malang Water

Abstract

AbstractIncreased sea surface temperatures due to global warming that occurred from the early to mid 2016 caused of coral bleaching in several locations in TWP Gili Matra. Observations of coral bleaching  obtained from coral colonies compotition affected by bleaching (50%), white (18%), death (1%) and was not affected (31%). These implications resulting decline in coral cover but not significant (F (1,013) = 0.333, p > 0.05) from 23,43% ± 2,61 SE in 2012 to 18,48% ± 4,14 SE in 2016 and a significant decrease (P (58,06) = 3,8e-06) recruitment of coral (coral Juvenil) from 6,66 ind.m-1 ± 1,04 SE in 2012 to 1,41 ind.m-1 ± 0,16 SE in 2016. the other impact is a significant reduction (P(20.84) = 0,00053, p <0,001) the abundance of reef fish from 28.733,26 ind.ha-1 ± 3.757,89 SE in 2012 to 11.431,18 ind.ha-1 ± 702,53 SE in 2016 and a decline in the biomass of reef fish but not significant (F (0,58) = 0,46, P> 0.05) from 506,56 kg.ha-1 ± 99,05 SE in 2012 to 438,41 kg.ha-1 ± 45,69 SE in 2016. The decline of coral recruitment resulted in the recovery of the affected areas bleaching becomes slow because of the juvenile new coral mostly dead. The second impact of bleaching is an abundance of fish decrease, indicating that is available only fish big size (adult) and very less of small fishes, including juvenile. Keywords: global warming, coral bleaching, coral cover, reef fishes AbstrakPeningkatan suhu permukaan laut akibat pemanasan global yang terjadi dari awal hingga pertengahan tahun 2016 memberikan dampak pemutihan karang di beberapa lokasi di TWP Gili Matra. Hasil pengamatan pemutihan karang didapatkan komposisi dari koloni karang yang terkena pemutihan (50%), pucat (18%), mati (1%) dan tidak terdampak 31%.  Implikasi ini mengakibatkan turunnya tutupan karang namun tidak signifikan (P(1.013)=0.333,p> 0,05) dari 23,43% ± 2,61 SE di tahun 2012 menjadi 18,48 % ± 4,14 SE di tahun 2016 serta penurunan signifikan (P(58,06) = 3,8e-06)rekruitmen karang (Juvenil karang) dari 6,66 ind.m-1 ± 1,04 SE di tahun 2012 menjadi 1,41 ind.m-1 ± 0,16 SE di tahun 2016. Dampak lainnya yaitu penurunan signifikan (P(20,84)=0,00053,p<0,001) kelimpahan ikan karang  dari 28.733,26 ind.ha-1 ± 3.757,89 SE di tahun 2012 menjadi 11.431,18 ind.ha-1 ± 702,53 SE di tahun 2016  serta penurunan biomassa ikan karang namun tidak signifikan (P(0,58)=0,46 ,P> 0,05) dari 506,56 kg.ha-1 ± 99,05 SE di tahun 2012 menjadi 438,41 kg.ha-1  ± 45,69 SE di tahun 2016. Hasil penelitian menunjukkan dampak bleaching menyebabkan sedikitnya rekrutmen karang yang mengakibatkan proses recovery area terdampak menjadi lambat dikarenakan juvenil karang baru sebagian besar mati. Dampak kedua dari bleaching ini yaitu kelimpahan ikan yang turun signifikan, hal ini mengindikasikan yang tersedia hanya ikan-ikan ukuran besar (dewasa) dan sedikitnya ikan-ikan kecil termasuk juvenile yang ditemukan.Kata kunci: pemanasan global, pemutihan karang, tutupan karang, ikan karang
