Simulation of two-dimensional currents to the depth and suspended sediment concentration in Aceh Besar Waters

Aceh Besar Waters are geographically located at 5.3° - 5.7°N and 95.1° - 95.6°E which border Indian Ocean, Andaman Sea, and Malacca Strait in the West, North, and East, respectively. The purpose of this study was to simulate the circulation of current and suspended sediment transport driven by southwest and northeast monsoon. Model discretization cover 0.5 x 0.5 arcminutes (925 x 925 m) of spatial resolution with time interval of 9 seconds. The parameters of the model are wind friction Cd = 1.285x10−3, bottom friction r = 0.0025, lateral eddy viscosity = 2500 m2/s. The primary data of estuary suspended sediment concentrations were collected in the coastal waters of Lhok Nga, Ulee Lheue, Lampulo, Alue Naga and Krueng Raya as input for the suspended sediment distribution model. The results of the study show that during southwest monsoon, the current in the western part of Aceh Besar Waters move northward and during northeast monsoon in the western and eastern part of the region, the current move toward south and west. Thus, the distribution of suspended sediments follows the direction of the current, where sediment concentrations are reduced when they are away from the coast.

Ichthyofauna of Aceh River, Aceh Province, Indonesia

Information on fish fauna in Aceh Besar District, Aceh Province, Indonesia is scared; hence, the objectives of the present study was to documented and to the analysis of the fish fauna in Aceh Besar District, Indonesia. The sampling was conducted from May 2016 to February 2017 at seven sampling locations around Aceh Besar District (Inong River, Seulimum River, Kreumireu River, Jreu River, Daroy River, and Naeuk River) and Banda Aceh City (the Aceh River Mouth at Lampulo and Alue Naga). The fish samples were caught using several fishing gears such as; casting nets, gillnets, handnet, and fish trap. The fish samples were taxonomically identification using Kottelat et al. (1993) and Nelson (1994). The results showed that a total of 250 individual of fishes belongs to 44 species, 34 genera and 25 families were recorded during the study. Oreochromis niloticus the alien species was widely distributed in Aceh Besar and Banda Aceh waters followed by Gerres filamentosus, Channa sariata and Puntius brevis.

The analysis of d90 and d50 sediment grain size in Alue Naga estuary, Banda Aceh City

The study of d50 and d90 sediment grain size in the Alue Naga estuary of Banda Aceh City, which was taken in December-March 2017 was completed. The purpose of the study is to determine the size of d50 and d90 sediment diameters and how it was dispersed along the estuarial area. The study used 15 stations sampling which was determined by purposive random sampling. The results of 15 sediment samples were then analyzed at the Marine Science Laboratory using a multilevel sieve method and evaluated using the Wentworth sieve analysis method. The results of the analysis showed that the largest particle size of d50 was 1.44 mm at station 14, and the biggest particle size of d90 of 3.5 mm was also obtained at station 14. The results attained were due to the dynamics of the ocean currents and the flow of the river interacting at station 14. This could happen because during the high tide, the dominant flow is coming from the sea, it causes a large size of d90 grained size sediment while during the low tide the dominant flow is from upstream of river so that the size of 50% sediment is also dominant.

Eco-friendly fishing gears based on code of conduct for responsible fisheries in the city of Banda Aceh, Indonesia

The aims of study was determine the fishing equipment that has the highest level of ecological friendliness. The study was conducted in March to May 2014 at Lampulo Fishing Port (PPS) and Alue Naga Fish Landing (TPI), Aceh Province, Indonesia. Descriptive method was used with the 175 fishermen as respondent divided into three categories, namely Purse Seine fishermen, Trammel Net, and Gill Net Fishermen. Data were etrieval using questionnaires and analyzed using descriptive analysis. The results of the study were described in graphical form, frequency and percentage (%). The results showed that the highest level of ecological friendliness fihing gear was gill net.

PERBEDAAN RENTANG WAKTU PERILAKU HARIAN KUNTUL KECIL (Egretta garzetta) DI KAWASAN MANGROVE ALUE NAGA KOTA BANDA ACEH

The study was conducted in May 2016, the purpose of this research to determine the difference of Egretta garzetta’s daily frequency, male and female behavior in mangrove area Alue Naga, Banda Aceh city. The method used in this study is focal animal sampling method to recording the daily behavior. Data processed using the qualitative and quantitative analysis. Analysis of the frequency of daily activity, carried out with the daily percentage. The results showed that daily behavior of Egretta garzetta include: feeding activity, perching activity, voice activity, moving activity, grooming activity, resting activity and flying activity. The highest time activity is females, that is perching and resting activity with each averaging for 70 minutes / day (28%) and 80 min / day (32%), and the lowest time span males and females is voice activity in average 1 min / day (0.4%). The conclusions derived from this research are: (1) There are 7 daily activities of Egretta garzetta in study location, include: feeding activity, perching activity, voice activity, moving activity, grooming activity, resting activity and flying activity. (2) The highest time activity is females, that is perching and resting activity.

19. Identification of Ectoparasites in the Mud Crab (Scylla serrata) from Alue Naga Coastal Waters Banda Aceh

This study aimsed to determine the type of ectoparasites on crab (Scylla serrata) in the water of Alue Naga Banda Aceh. The samples of this study were 10 heads of mud crabs were taken from the Alue Naga waters Banda Aceh and taken to the Laboratory of Parasitology. Veterinary Medicine Faculty of Syiah Kuala University Banda Aceh to identify the take ectoparasites on mud crab (Scylla serrata) by observing the outer body of the organism, then noted bleeding, wounds or swelling and pay attention to the type of organism that is attached to the body of mud crab, then dredge the outer parts of the body like the carapace, foot path, foot pool and gills were take it and then tweezers and then putting the object glass that has been provided and observed with a microscope with 100 times magnification and see what kind of ectoparasites that have been found and then compare with the identification key. From the results of this study concluded that ectoparasites which infects mud crab (Scylla serrata) in the waters of Alue Naga Banda Aceh come from genus Chilodonella sp. Whichare predilections in the gills with a prevalence rate of 10%.

Identification and Distribution of Species Culicoides spp. (Diptera: Ceratopogonidae) of Broiler in Banda Aceh

A research has been done to identify the distribution of Culicoides species in Banda Aceh. Culicoides samples were collected by using modified Center for Disease Control (CDC) Miniatur Light Trap. All Culicoides samples has choice a small measured, were identified morfologically. The result showed that the number species Culicoides has caught in Ulee Kareng are: C. huffi, C. arakawae and C. shultzei, whereas in Alue Naga are C. huffi and C. shultzei. The distribution of species Culicoides in Ulee Kareng are: C. huffi has 22, C. arakawae 13 and C. shultzei 11. The average distribution of Culicoides in Alue Naga are C. huffi has 11 and C. shultzei has 4 .
