Abstract

Anoi Itam Beach (AIB), located in the eastern part of  Weh Island, has the sediment characteristic of dark-sand color. Climatologically, the beach is influenced by two seasons, i.e., south-west (SW) monsoon and northeast (NE) monsoon. Sediment data are collected in the upper and lower littoral zones that are divided into six stations alongshore. Data were collected on October 2016 and April 2017, representing post (SW) monsoon and post-NE monsoon events. To examine the effect of seasonal, sediments statistics, e.g., mean, sorting, skewness, and kurtosis, have been calculated. AIB was characterized as well sorted to poorly sorted sediment. Sediments were identified as mesokurtic in October, varied to leptokurtic and platikurtic in upper littoral and lower littoral, respectively, in April. Grain size in both upper and lower littoral had increased from October to April. The impact on sediment sortation was minor due to the seasonal difference. Sediments in the upper littoral vary slightly skewed than lower littoral, which response to a more positively skewed during seasonal change from SW-monsoon to NE monsoon. The results suggested that lower littoral provide high variability of sediment characteristics depend on the season.

Abstract. The objective of this research was to find out the effectiveness of henna leaf extract (Lawsonia inermis L.) on A. hydrophila in vitro and its effect on the survival rate of Clarias gariepinus that infected by those bacterias in vivo. The research was conducted at chemistry laboratory of Teacher Training and Education Faculty, Syiah Kuala University and at Microbiology laboratory, Brackishwater aquaculture Department Center, Ujong Batee on Avril to September, 2015. The research involved in vitro test with the inhibition zone as measured parameter and in vivo test with the survival rate value as measured parameter. The treated concentrations were 1, 2, 3, 4 and 5% of extract. The result of in vitro test showed that henna leaf extract was effective against A. hydrophila with the inhibition zone for 1, 2, 3, 4, and 5% extract were 5.45; 5.7; 6.5; 7.5; and 9.6 mm, respectively. The result of ANOVA test showed that henna leaf extract has a significant effect on the survival rate of catfish (P0.05). The best survival rate was obtained at 4% of extract  concentration.  Keywords: Aeromonas hydrophila; henna leaf extract; catfishAbstrak. Penelitian ini bertujuan untuk mengetahui efektivitas ekstrak daun inai (Lawsonia inermis L.) terhadap A. hydrophila secara in vitro dan pengaruhnya secara in vivo terhadap kelangsungan hidup ikan lele sangkuriang (Clarias gariepinus) yang terinfeksi bakteri ini dengan cara perendaman. Penelitian ini dilakukan di Laboratorium kimia, FKIP Unsyiah dan Laboratorium Mikrobiologi Balai Budidaya Perikanan Air Payau (BBAP) Ujong Batee pada dari bulan April hingga bulan September 2015. Penelitian ini meliputi uji in vitro dengan parameter uji berupa zona hambat ekstrak terhadap bakteri dan uji in vivo dengan parameter uji berupa nilai kelangsungan hidup ikan lele sangkuriang pasca perlakuan dengan ekstrak. Konsentrasi perlakuan yang dilakukan adalah 1, 2, 3, 4, dan 5%. Hasil uji in vitro menunjukkan bahwa ekstrak daun inai (Lawsonia inermis L.) terbukti efektif terhadap Aeromonas hydrophila dengan nilai zona  hambat secara berturut-turut terhadap konsentrasi 1, 2, 3, 4 dan 5% adalah 5,45; 5,7; 6,5; 7,5; dan 9,6 mm. Hasil uji ANOVA menunjukkan bahwa ekstrak daun inai berpengaruh nyata (P0,05) terhadap kelangsungan hidup ikan lele sangkuriang. Tingkat kelangsungan hidup ikan terbaik diperoleh pada konsentrasi ekstrak 4%.Kata kunci : Aeromonas hydrophila; ekstrak daun inai; ikan lele sangkuriang

Abstract. The objective of this research was to determine the characteristics and mineral content of coastal sand from  Lhokmee, Beureunut, and Leungah Aceh Besar District. The sand analysis was conducted at Material Laboratory of Mathematics and Natural Sciences Faculty, Syiah Kuala University from March to April, 2014. Samples were collected using purpossive sampling method. The observed physical characteristics of this research were sand color, shape and particle size. The mineral content was analysed using X-Ray Diffraction (XRD) and Joint Committee for Powder Diffraction Standard (JCPDS) program. The result showed that Lhok Mee coastal sand was physically characterized as white, sub-angular rounded shape and 0.21 mm of size, while Beureunut coastal sand was light brown, rounded-well rounded shape and 0.19 mm of size, then Leungah coastal sand was black, angular-well rounded shape and 0.13 mm of size. Based on  mineral content showed that Lhok Mee, Beureunut, and Leungah coastal sand were dominated by SiO3, SO3 and Fe3O4, respectively. All identified minerals at all stations were classified as volcanic minerals of lithogenous sediment. Keywords: Beach sands; Color difference; Mineral content; Shape; Particle size.

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.
