Abstract

Lokop is one of the villages in Serbajadi District, East Aceh Regency, Aceh Province. The village has a watershed named the river Lokop. This river is located in the Leuser Ecosystem Area which is inhabited by various aquatic biota, especially fish, with the level of diversity and distribution patterns that need to be studied and analyzed conoftened. This study used the purposive sampling method, with the parameters being the level of diversity and distribution patterns of fish in the Lokop river. Data collection was carried out at 5 observation stations based on the typology of river habitat, each station was divided into three substations representing parts of the basin, river bank and river basin approximately 50 m apart. Fish sampling is carried out at each station using a plot of 10 x 10 m2. The number of plots at each station is 9 plots with a total of 45 plots. The results showed that the diversity index (H') value of fish in the Lokop river was 2.39 in the moderate category and the distribution pattern of fish in the Lokop river has a uniform pattern and clusters. Out of a total of 17 species obtained, 8 species (47%) were clustred, 8 species (47%) were uniformly distributed and 1 species (6%) could not be analyzed because only one individual was found.Keywords:FishRiverDiversityDistribution

Abstract

The Banggai cardinalfish Pterapogon kauderni is the Indonesian national marine ornamental fish mascot, and an object of national and international conservation concern. The endemic population of this species is limited to the Banggai Archipelago in Central Sulawesi, Indonesia and a few nearby islands in North Maluku. In addition, introduced populations have become established, mainly along ornamental fish trade routes. The National Action Plan for Banggai Cardinalfish Conservation (NAP-BCFC) calls for monitoring and management of all P. kauderni populations. A survey of the Luwuk introduced P. kauderni population was carried out in October 2021.   Data were collected at three sites with established P. kauderni populations: the ferry harbour, public harbour (Teluk Lalong) and a recreational area on the nearby coast (Kilo 5). P. kauderni were recorded by microhabitat association and size class (recruits, juveniles, adults). Data collected were compared with data from previous surveys where available. With the exception of one group in a sea anemone at Kilo 5, all P. kauderni were associated with Diadema sea urchins (D. setosum at all sites; D. savignyi at Kilo 5). At Kilo 5 P. kauderni the population structure indicates the possible capture of market-sized juveniles. Overall abundance was also lower compared to the polluted but unfished harbours. The proportion of recruits was significantly negatively correlated with the ratio of adult P. kauderni to Diadema urchins. The results will inform regional legislation currently in preparation to support sustainable management of P. kauderni populations, habitat and microhabitat in Central Sulawesi, as well as contributing to NAP-BCFC targets.Keywords:Banggai cardinalfishEndangered speciesDiademaMicrohabitat,MonitoringOrnamental fisheryLocal regulation

Abstract

Echinoderm community was studied at the Mandalika Beach which is the main habitat of nyale worms in the southern coast of Lombok Island, from July to September 2017. The aim of study was to describe community structure of Echinoderm fauna and population structure of predominant species. Data on species richness and its abundance were collected using transect-quadrate methods. Five transects were laid haphazardly seaward that may represent the whole reef flat with about 200 m length and 100 m wide.  On every 10 meter along the transect length a 5x1 m2 quadrate was made, that overall there were 44 quadrates. The results showed that only eight species of Echinoderms found in the quadrate samples, i.e. sea urchin Echinometra mathaei (Echinoidea), and brittle stars, Ophiocoma scolopendrina, O. echinata, O. erinaceus, Ophiomastix annulosa and Ophioderma sp. (Ophiuroidea). Two other Echinoidea were also found outside the quadrates, i.e. Echinothrix calamaris and Diadema setosum. Simpson diversity index (D) was 1,243, eveness index (E) was 4,023, Shanon-Winner diversity index (H) was 0,430 and equatibility index (J) was 0,267. Sea urchin E. mathaei was the most predominant population (89,38% of total composition) with average abundance 11,87±22,37 individual m2. Brittle star O. scolopendrina come the second predominant population (7,31%) with average abundance 0,86±2,43 individual m2. The other four brittle stars had very low proportion (2%) and low abundance ( 0,20  individual m2). Population stucture showed that these two populations mostly consisted of reproductive members. Ecological interactions of these two predominant Echinoderms should be studied in more detail on interactions among of the Echinoderms and nyale worms. Keywords: Ophiocoma, Echinometra, Nyale, Lombok Tengah, population structure ABSTRAKPenelitian komunitas Echinodermata dilakukan di Pantai Mandalika yang menjadi habitat utama cacing nyale, pada bulan Juli-September 2017. Penelitian ini bertujuan mendeskripsikan struktur komunitas Echinodermata dan struktur populasi spesies yang dominan. Data kekayaan spesies dan kelimpahan diambil dengan metode transek kuadrat. Lima transek diletakkan tersebar ke arah laut pada pantai yang panjangnya sekitar 200 m dan lebar 100 m tersebut. Setiap titik 10 meter pada transek dibuat kuadrat ukuran 5 m2, dengan jumlah kuadrat sampel seluruhnya 44 kuadrat. Hasil penelitian menunjukkan bahwa komunitas Echinodermata mempunyai kekayaan spesies yang rendah di Pantai Mandalika. Organisme Echinodermata yang dijumpai hanya 8 (delapan) spesies, yaitu landak laut Echinometra mathaei (Echinoidea), serta lima jenis bintang mengular, Ophiocoma scolopendrina, O. echinata, O. erinaceus, Ophiomastix annulosa dan Ophioderma sp. (Ophiuroidea). Di luar kuadrat tercatat dua jenis landak laut lainnya, yaitu Echinothrix calamaris dan Diadema setosum, dengan kelimpahan yang sangat rendah. Indeks-indeks komunitas pada umumnya rendah. Indeks diversitas Simpson (D) 1,243, indeks keseragaman (E) 4,023, indeks keanekaragaman spesies Shanon-Winner (H) 0,430 dan indeks kesetaraan (J) 0,267. Landak laut E. mathaei sangat dominan (89,38%) dengan kelimpahan rata-rata 11,87±22,37 individu m-2 di dalam komposisi komunitas Echinodermata. Bintang mengular O. scolopendrina menempati urutan dominansi kedua (7,31%) dengan kelimpahan rata-rata 0,86±2,43 individu m-2, sedangkan empat bintang mengular lainnya mempunyai proporsi kurang dari 2% dan kelimpahan rata-rata kurang dari 0,20  individu m-2. Struktur populasi E. mathaei dan O. scolopendrina menunjukkan bahwa sebagian besar anggota populasi mempunyai ukuran reproduktif. Kehadiran hewan Echinodermata tersebut di habitat cacing nyale (Eunicidae, Polychaeta) menuntut penelitian lanjutan tentang peran ekologis dari masing-masing hewan Echinodermata dan interaksinya dengan cacing nyale.Kata kunci: Ophiocoma, Echinometra, Nyale, Lombok Tengah, Struktur populasi

Abstract. The issue of mercury pollution in Aceh waters, Indonesiadue to gold mining activities hasbeen a polemic in local media and Aceh Local Government and the communities have much concern on this case. The impact of mercury pollution in the Teunom and Tangse (Aceh)rivers was often assumed that it has similarity with Minamatapollution in Japan. This article intends to enlighten the characteristic mercury either as elements or compounds including methyl mercury which is highly toxic. Gold mining using elemental mercury is poorly soluble in water, the solubility is only 0.06 g per ton of mercury but the solubility can increase indark the sea-bed and ina lot of dissolved oxygen. Based on the properties of solubility, it is understood that the mercury levels in the Teunom and Tangse rivers still below the tolerance limit, but the gold mining activities still bringsthe risk of environmental damage especially inadequate supervision. Many researchers were trying to prove the natural conversionfrom mercury into methyl mercury (biomethylation) but they usedthe salt instead of the elemental mercury in their experiments. Methyl mercury is found in nature, but the process mercury conversion into methyl mercury compound is still controversial and it has not obtained adequate evidence for the natural alteration,therefore gold pollution which is due to releasing elemental mercury into environment might not be analogue to Minamata case.Keywords: Aceh; Methyl-mercury; Minamata; Mining; Gold Abstrak. Informasi pencemaran merkuri di perairan Aceh dan kaitannya dengan aktivitas pertambangan emas telah menjadi polemik sehingga menjadi perhatian Pemda Aceh dan Masyarakat. Dampak pencemaran merkuri di Sungai Teunom dan Tangse sering dianalogikan dengan kasus pencemaran merkuri di teluk Minamata, Jepang. Artikel ini bermaksud memberi pencerahan kharakteristik merkuri baik sebagai unsur maupun sebagai senyawa seperti metil merkuri yang sangat beracun. Penambangan emas menggunakan unsur merkuri yang sukar larut dalam air, kelarutannya hanya 0,06 g per ton unsur merkuri  namun kelarutannya dapat meningkat jika di dasar laut yang gelap dan banyak oksigen terlarut. Berdasarkan sifat kelarutannya, dapat dipahami bahwa kadar merkuri di Sungai Teunom masih di bawah batas toleransi, namun aktivitas penambangan emas tetap saja memiliki resiko kerusakan lingkungan apalagi jika tidak mendapat pengawasan yang memadai. Banyak peneliti berusaha membuktikan perubahan merkuri menjadi metil merkuri (biometilasi) tetapi mereka menggunakan garam merkuri dan bukan unsur merkuri dalam ekperimen mereka. Metil merkuri memang ditemukan di alam tetapi proses perubahan dari senyawa merkuri menjadi metil merkuri masih diperdebatkan dan belum diperoleh bukti yang kuat perubahan dari unsur merkuri menjadi metil merkuri dalam air sehingga di Peraian Aceh belum tentu tercemar metil merkuri sebagaimana kasus Minamata.Kata kunci: Aceh; metil-merkuri; minamata; penambangan; emas
