Penelitian ini bertujuan untuk mengetahui perubahan garis pantai di sepanjang pantai timur laut Kabupaten Aceh Besar dan Pidie pada tahun 2002 hingga 2014 dengan interval selama dua tahun. Penelitian ini dilaksanakan pada bulan Januari – Februari 2016 dimulai dari pinggir pantai Desa Krueng Cut, Aceh Besar sampai Kecamatan Kembang Tanjong, Pidie. Metode Penelitian memanfaatkan teknologi Sistem Informasi Geografis (SIG) dan penginderaan jauh, dengan mengambil data citra satelit Landsat 7 dan Landsat 8 yang diproses menggunakan ArcGIS 10.5. Hasil penelitian ini menunjukkan bahwa perubahan garis pantai yang terjadi sangat signifikan untuk perubahan abrasi maupun sedimentasi.Kata Kunci: Garis Pantai, Abrasi, Sedimentasi, Penginderaan Jauh, Sistem Informasi Geografis (SIG), ArcGIS 10.5.ABSTRACTThis study aims to determine the shoreline changes along the northeastern coast of Aceh Besar and Pidie districts in 2002 to 2014 at intervals of two years. This research was conducted in January - February 2016 starting from coastal village of Krueng Cut, Aceh Besar until Kecamatan Kembang Tanjong, Pidie. The research method utilizes Geographic Information System (GIS) and remote sensing technology, taking Landsat 7 and Landsat 8 satellite images processed using ArcGIS 10.5. The results of this study indicate that the shoreline changes that occur are very significant for abrasion and sedimentation changes.Keywords: Coastline, Abrasion, Sedimentation, Remote Sensing, Geographic Information System (GIS), ArcGIS 10.5.

Reef fish utilize coral reef ecosystems as a place to live, foraging, spawning and nurturing. This study aims to determine the abundance of species, diversity and biomass of reef fish found in the waters of Ujong Pancu, Aceh Besar district. This research was conducted in October 2017, there were 5 research location. Data was collected using the Underwater Visual Census (UVC) method. The result show that the highest abundance of reef fish was found in waters of Lhok Mata Ie with a value of 5311.71 Ind/ ha. While the lowest abundance of reef fish was found in Tuan Island waters with a value of 896.67 Ind/ ha. Overall diversity of Ujong Pancu waters reefs is included in the medium-high category. The highest average biomass of reef fish is found in the water of East Batee Island with a value of 100.69 Kg/ ha. While the lowest average biomass of reef fish is found in the waters of West Batee Island with a biomass value 23.87 Kg/ ha. Keywords : Abundance, biomass, diversity, reef fish, Ujong Pancu

We investigated the sediment properties and distribution in Balohan Bay, which is located in southern Weh Island, Aceh Province. The aim of this research was to clarify the sediment distribution mechanism in the Balohan Bay using a statistical approach. Samples were collected on January 2016 using coring method. Sediment grain-size distribution from 14 stations was obtained using wet sieve analysis. A large amount of fine sand and very fine sand were found in Balohan Bay, as a result of several tributaries discharged in those areas. The sediment distribution in eastern stations showed an indication as a coarser size and a poorer sorted area, as they were adjacent to the steep cliff.

ABSTRAKPenelitian ini bertujuan untuk mengetahui tutupan karang keras pada waktu sebelum (tahun 2015) saat (2016) dan sesudah pemutihan karang (2017) di Krueng Raya, Aceh Besar. Penelitian ini dilakukan pada bulan April 2017 di Krueng Raya, Aceh Besar. Pengambilan data dilakukan di 3 stasiun pengamatan menggunakan metode PIT (Point Intercept Transect) yang meliputi: Benteng Inong Balee, Ahmad Rhang Manyang, dan Lhok Mee. Hasil penelitian menunjukkan persentase rata - rata tutupan karang keras tahun 2015 sebesar 52,83% berkategori baik, tahun 2016 sebesar 32,43% berkategori sedang dan tahun pada tahun 2017 persentase tutupan karang keras menjadi 22,90% dan masuk ke dalam kategori rusak. Terdapat sebanyak 16 genus karang (2015), 18 genus karang (2016) dan 8 genus karang 8 (2017). Indeks Mortalitas (IM) tahun 2015 berkisar antara 0,02-0,20 (tingkat kematian karang yang rendah), tahun 2016 berkisar antara 0,13-0,49 (kematian karang rendah), tahun 2017 berkisar antara 0,63-0,79 (tingkat kematian karang tinggi). Hasil penelitian ini menunjukkan bahwa persentase tutupan karang keras mengalami penurunan hingga mencapai ±50% yang diakibatkan oleh pemutihan karang pada Perairan Krueng Raya Aceh Besar. ABSTRACTThe aim of this study was to determine hard coral cover at the time before (2015), during (2016) and after coral bleaching (2017) in Krueng Raya, Aceh besar. This study was conducted on April 2017 in Krueng Raya, Aceh Besar. Data collection was carried out at 3 observation stations using the PIT (Point Intercept Transect) method which included : Fort Inong Balee, Ahmad Rhang Manyang, and Lhok Mee. The results showed that the average percentage of hard coral cover in 2017 was 22.90% (bad category), it was lower than in 2016 32.43% (medium category) and in 2015 was 52.83% (good category). There were found 16 genera of coral (2015), 18 genera of coral (2016), and 8 genera of coral (2017). Mortality Index (MI) in 2015 ranged between 0.02-0.20 (low coral mortality rate), in 2016 ranged between 0.13-0.49 (low coral mortality rate), in 2017 ranged between 0.63-0.79 (high coral mortality rate). The results of this study indicate that the percentage of hard coral cover has decreased to reach 50% due to coral bleaching in the waters of Krueng Raya Aceh Besar.

Lingula sp. is one of the genera of the Brachiopoda phylum that lives in the intertidal zone or areas that are affected by tides. The purpose of this study was to determine the population structure of Lingula sp. through the approach of population structure, density, distribution patterns, length and weight relationship and with physical and chemical parameters in the waters of Alue Naga, Syiah Kuala District, Banda Aceh City. The method used in this research is a purposive random sampling method. The results show that the growth pattern of Lingula sp. is classified as negative allometric at three research sites in Alue Naga waters, based on the value of b 3. The density of Lingula sp. was the highest at site 1 with a total of 17.7 ind/m2. While the density of Lingula sp. was the lowest at site 3 with a total of 9.7 ind/m2. The distribution of Lingula sp. at the three sites were uniform, with morisita index (Id) values of 0.352, 0.257, and 0.208 for sites 1, 2, and 3 respectively. In addition, the environmental factors of the three research sites in Alue Naga waters are within the normal limits of life for Lingula sp.Keywords: Alue NagaLingula sp. Population structure
