Abstract

The objectives of the present study was to determine the best age of the zygote for gynogenesis of seurukan fish (Osteochilus vittatus) using heat shock treatment. The completely randomized design was utilized in this study. Five levels of zygote age were tested, namely: 3 minutes, 5 minutes, 7 minutes, 9 minutes and 11 minutes after fertilization and one control treatment (without heat shock). The zygotes were shocked at the temperature of 38oC for 60 seconds and every treatment was done at three replications. The ANOVA test showed that the zygote age gave the significant effect on the triploidy level and growth performance of the seurukan fish (P0.05). The highest percentage of the triploid  fish were found at zygote age of 3 minutes, but this value was not different significantly with 5 min, 7 min and 9 min. The highest weight gain  was found at zygote age of 3 minutes, but this value was not different significantly with 5 min, 7 min and 9 min. In addition, the highest of length gain was also recorded at zygote at zygote age of 3 minutes, but this value was not different significantly with 5 minutes of the zygote (P0.05). It is concluded that the best zygote age of the seurukan fish for gynogenesis using heat shock treatment was 3 minutes after fertilization.Penelitian ini bertujuan untuk mendapatkan umur zigot terbaik untuk proses ginogenesis ikan seurukan (Osteochilus vittatus) dengan menggunakan kejutan suhu panas. Metode yang digunakan adalah eksperimen dengan model Rancangan Acak Lengkap faktor tunggal dengan enam taraf perlakuan, masing-masing perlakuan dengan tiga kali ulangan. Kejutan suhu yang diberikan yaitu 38oC dengan lama kejutan 60 detik, dengan perlakuan yaitu: kontrol (tanpa perlakuan kejutan panas), umur zigot 3 menit setelah pembuahan, umur zigot 7 menit setelah pembuahan, umur zigot 9 menit setelah pembuahan dan 11 menit setelah pembuahan. Uji ANOVA menunjukkan bahwa pemberian kejutan suhu panas pada umur zigot yang berbeda berpengaruh nyata terhadap triploidy dan pertumbuhan ikan seurukan (P0,05). Persentase ikan triploid tertinggi dijumpai pada perlakuan 3 menit setelah pembuahan, nilai tidak berbeda nyata dengan perlakuan 5 menit, 7 menit dan 9 menit. Pertambahan bobot tertinggi dijumpai pada umur zigot 3 menit setelah pembuahan, nilai ini tidak berbeda nyata dengan perlakuan 5 menit, 7 menit dan 9 menit. Pertambahan panjang tertinggi dijumpai pada perlakuan 3 menit setelah pembuahan, nilai ini tidak berbeda nyata dengan perlakuan 5 menit (P0,05). Berdasarkan hasil tersebut dapat disimpulkan bahwa umur zigot yang berbeda berpengaruh terhadap triploidy, dan umur zigot terbaik adalah 3 menit setelah pembuahan

Abstract

ABSTRACTThis research was aimed to determine and study the abundance of benthic foraminifera on coral reef ecosystem and mangrove in the Coastal Waters of Lamreh, Aceh Besar. This research was conducted from April to May 2016 using purposive sampling method. Samples of foraminifera benthic were collected using a corer (paralon pipe). 229 individuals of foraminifera benthic belonging to 29 spesies was found. The most abundant species found in coral reef area was Spiroloculina sp. (339,70 ind/m2 or 14,17%) and Spriloculina hyalina (305,73 ind/m2 or 13,64%), while in mangrove area was Calcarina calcar  with the abundance value of 356,69 ind/m2 or 20,59%. In this area the sediment was dominated by sandy sediment. Probably, It was due to the strong current and wave in the coastal waters of lamreh which inhibit the desposition of fine sediment. Keywords: Abundance, coral reefs, foraminifera, mangrove,  Coastal, sediments ABSTRAKPenelitian ini bertujuan untuk menentukan dan mengkaji kelimpahan foraminifera bentik pada ekosistem terumbu karang dan mangrove di Perairan Pantai Lamreh Aceh Besar. Penelitian ini dilaksanakan pada bulan April sampai Mei 2016 dengan metode purposive sampling, dimana pengambilan sampel foraminifera bentik menggunakan corer (pipa paralon). Hasil penelitian foraminifera bentik ditemukan sebanyak 29 spesies dengan total individu sebanyak 229 individu. Pada kawasan terumbu karang spesies tertinggi ditemukan pada spesies Spiroloculina sp. dengan kelimpahan 339,70 ind/m2 (15,75%) dan Spriloculina hyalina 305,73 ind/m2 (14,17%), sedangkan pada ekosistem mangrove spesies tertinggi ditemukan pada spesies Calcarina calcar dengan kelimpahan 356,69 ind/m2 (20,59%), Pada kawasan ini, sedimen yang dihasilkan dominan pasiran. Hal diduga karena di kawasan perairan Pantai Lamreh memiliki arus dan gelombang yang kuat sehingga menghambat terjadinya pengendapan sedimen yang berukuran halus. Kata kunci: Kelimpahan, Foraminifera, Sedimen, Terumbu karang, Mangrove, Pantai Lamreh.

Abstract. Mismanaged anthropogenic debris land-based has generated the waste entering the river runoff. It was documented that the ocean has been affected ecologically by the waste. Therefore, the data availability of riverine inorganic debris is crucial in implementing mitigation strategies. This study was a preliminary study to identify the inorganic debris floating on the Krueng Aceh River. This study aimed to obtain data of floating inorganic debris types and percentages found at the estuary of Krueng Aceh River that can be used as a reference in managing the riverine waste. It was conducted at the estuary of Krueng Aceh River, Banda Aceh, during March to April 2019. The samples were collected twice a week by installing 4 m x 2 m nets on both sides of the river for six hours. It was identified seven categories of inorganic debris were plastic, foamed plastic, metal, glass, rubber, paper and cardboard, and others. Plastic category as the most floated on Krueng Aceh River with the percentage of 77.8% consists of drinking water bottles and cups, bottle caps, cigarettes, cigarettes lighter, bubble wrap, plastic bags, plastic ropes, monofilament line, straws, and drink package rings. The amount of drinking water cups was dominantly trapped (32%) and identified as many as 28 brands. The plastic debris was assumed originating from anthropogenic activities, and mismanaged land-based garbages.It is concluded that the plastic category, especially drinking water cups, was the most floating on the Krueng Aceh River.Keywords: Mineral water bottles, floating plastic debris, Krueng Aceh River Abstrak. Sampah anorganik akibat aktivitas manusia yang tidak dikelola dengan baik telah menghasilkan limbah yang berada di aliran sungai. Sebagian dari sampah–sampah tersebut akan berakhir di lautan sehingga menimbulkan dampak negatif secara ekologi. Oleh karena itu, ketersediaan data sampah anorganik di aliran sungai diperlukan bagi pengelolaan sampah yang lebih baik. Penelitian tentang sampah anorganik di muara Sungai Krueng Aceh merupakan penelitian awal untuk menyediakan data jenis dan persentase sampah anorganik yang ditemukan di muara Sungai Krueng Aceh. Tujuan dari penelitian ini adalah mengidentifikasi jenis-jenis dan persentase sampah anorganik yang terapung di muara Sungai Krueng Aceh sehingga dapat menjadi acuan bagi pengelolaan sampah di aliran sungai. Penelitian ini dilakukan di muara Sungai Krueng Aceh, Kota Banda Aceh pada bulan Maret-April 2019. Pengumpulan sampel dilakukan dua kali dalam seminggu dengan memasang jaring 4 m x 2 m di kedua sisi sungai selama enam jam. Hasil identifikasi dikelompokkan ke dalam tujuh kategori sampah anorganik, yaitu kategori plastik, busa, kaca dan keramik, logam, kertas dan kardus, karet, serta kategori lainnya. Kategori plastik memiliki persentase terbesar dengan nilai 77,8% yang terdiri dari jenis bentuk botol dan gelas Air Minum Dalam Kemasan (AMDK), puntung rokok, pemantik, bubble wrap, kantong plastik, tutup botol, tali plastik, monofilament line, sedotan, dan cincin paket minuman. Persentase AMDK berbentuk gelas lebih tinggi daripada bentuk botol dengan 28 merek yang teridentifikasi. Sampah plastik tersebut diduga berasal dari aktivitas masyarakat di sepanjang Sungai Krueng Aceh dan akibat pengelolaan sampah yang belum baik sehingga sampah memasuki aliran sungai. Berdasarkan hasil penelitian dapat disimpulkan bahwa sampah plastik terutama sampah AMDK bentuk gelas ditemukan paling banyak mengapung di Sungai Krueng Aceh.Kata kunci: Air Minum Dalam Kemasan (AMDK), sampah plastik apung, Sungai Krueng Aceh

Abstract

This study aimed to examine the influences of the Indian Ocean Dipole (IOD) on rainfall in three districts in South Aceh. The analysis was undertaken using Dipole Mode Index (DMI) data and five years of rainfall (2016 to 2020) in West Labuhan Haji, Tapak Tuan, and Bakongan areas. This research employed a correlation analysis and the Principal Component Analysis, followed by Cluster Analysis to investigate the relationship between IOD and rainfall at the study location. The negative IOD occurred in 2016, and the positive IOD occurred in 2017, 2018, 2019, and 2020. The strongest positive DMI was in October 2019 (1.123˚C), while the strongest negative DMI was in July 2016 (0.661˚C). Generally, the sub-districts of West Labuhan Haji, Tapak Tuan, and Bakongan always have high rainfall. The highest rainfall in West Labuhan Haji was recorded in January 2017 (1014 mm/month), in Tapak Tuan in November 2017 (1073 mm/month), and in Bakongan in July 2020 (605 mm/month). The correlation between DMI and rainfall in the three locations shows different findings. Although it was very small, the IOD affected the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. In West Labuhan Haji, the highest correlation was in lag 1 (0.188); in Tapak Tuan, the highest correlation was in lag 2 (0.156), while in Bakongan, the highest correlation was in lag 2 (-0.191). The correlations in these three locations are considered weak. Thus, the IOD is not the main factor affecting the rainfall in West Labuhan Haji, Tapak Tuan, and Bakongan. As South Aceh is located in windward, the orographic effect may influence high rainfall in this region.Keywords:DMIRainfallPrincipal component AnalysisWest Labuhan HajiTapak TuanBakongan

Abstract

The objective of this study was to determine the mercury content in sediment in the waters of Aceh Jaya coastal. The research was carried out in the Estuary of Krueng Sabee, Panga, and Teunom River on October 2015. Samples were analyzed using the Atomic Absorption Spectrophotometer (AAS) at the Laboratory of Chemistry, Mathematics and Natural Sciences Faculty, Syiah Kuala University. It was found that the Hg content in sediment of Krueng Sabee, Panga, and Teunom were 0.76, 0.68, and 1.03 mg/kg, respectively. Hg metal content in the sediment at all stations remained below the threshold. Despite,  the correlation between Hg content and sediment size in this study was weak, but there was a tendency the finer sediment size the higher Hg content found in sediment. However, heavy metal from water was easier to be deposed and embedded in fine sediment.Tujuan dilakukannya penelitian ini adalah untuk mengetahui sebaran logam berat merkuri (Hg) yang terkandung pada substrat dasar di beberapa muara sungai Kabupaten Aceh Jaya. Pengambilan data dilakukan pada Bulan Oktober 2015 di Krueng Sabee, Krueng Panga, dan Krueng Teunom. Sampel substrat diambil berdasarkan metode coring menggunakan pipa paralon, Atomic Absorption Spectrophotometer (AAS) atau Spektrofotometer Serapan Atom digunakan untuk mendapatkan data kandungan logam berat Hg pada substrat, sementara metode ayak basah digunakan untuk mendapatkan data ukuran butiran. Kandungan merkuri (Hg) dalam substrat Krueng Sabee, Krueng Panga, dan Krueng Teunom masing-masing adalah 0,76; 0,68 dan 1,03 mg/kg. Terlihat kecenderungan substrat dengan butiran yang halus mengandung kadar merkuri yang lebih tinggi, dimana sifat merkuri yang mudah berikatan dengan zat organik mempermudah pengendapan pada bentuk butiran yang halus.
