Most of the coastal areas of Aceh Besar are areas of accumulation of organic compounds, one of which is Organic Carbon (OC). The purpose of this study was to analyze the chemical content by looking vertically at the content of OC, soil pH and Calcium Carbonate (CaCO3) on the coast of Aceh Besar District. Analysis of the OC content using the Walkley and Black method, while to analyze the Calcium Carbonate (CaCO3) using the Titrimetric method. Especially for the analysis of soil pH, only use a pH meter. The results showed that each station had different levels of OC and carbonate. Generally, the presence of OC decreases with depth, while the carbonate content varies. Especially for soil pH, the pH is relative to the alkaline state for each depth. The range of OC content for all stations is 0.18 – 2.48%, Carbonate 5.36 – 13.27% and pH 6.37-8.73.Keywords:CoastalOrganic CarbonCarbonateSoil pH

The availability of accurate land data is useful in planning, policymaking, regional development, and preserving the environment. Banda Aceh is the center of education and development in Aceh, Indonesia, which is located in the coastal area. The tsunami has had a significant impact on development and settlements in Banda Aceh. Currently, settlements in Banda Aceh rapidly grow also the need for land and water resources. Therefore, mapping the potential for residential land in Banda Aceh is required. This study examines land suitability in Banda Aceh based on the FAO salinity criteria and spatial data analysis by remote sensing methods. Based on the results, it is known that Banda Aceh has land suitable for settlement of around 85% or 2975 hectares. These areas are generally located close to watersheds and receive sufficient freshwater input. Meanwhile, areas far from rivers and close to the coast have brackish salinity. This area is not suitable as a residential area. There are about three sub-districts in Banda Aceh which are not suitable for settlement.Keywords:KrigingRemote sensingSettlementSalinity mappingCoastalBanda Aceh

Abstrak. Ekosistem gambut Rawa Tripa merupakan salah satu ekosistem hutan rawa gambut yang ada di Indonesia. Rawa Tripa adalah kawasan gambut yang memiliki kedalaman gambut lebih dari 3 meter. Sesuai dengan SK Presiden No.32 tahun 1990 yang menyatakan bahwa, “hutan gambut dengan kedalaman lebih dari 3m merupakan daerah yang harus dikonservasi dan tidak diperbolehkan untuk dikonversi menjadi lahan pertanian”. Tetapi, peraturan ini tidak dapat menahan laju deforestasi oleh pemegang Hak Guna Usaha (HGU) kelapa sawit di kawasan Rawa Tripa yang terjadi sejak tahun 1995. Penelitian ini bertujuan untuk menganalisis laju deforestasi dan mengetahui perubahan tutupan hutan beserta luas deforestasi yang terjadi dalam kurun waktu 8 tahun mulai tahun 2013 sampai 2021 di kawasan Rawa Tripa. Penelitian ini dilakukan dengan teknik penginderaan jauh (remote sensing) menggunakan metode klasifikasi terbimbing (supervised classification) yaitu interactive supervised classification. Hasil penelitian dengan teknik penginderaan jauh diperoleh nilai perubahan tutupan lahan dari tahun 2013 sampai dengan 2021 di ekosistem gambut Rawa Tripa Provinsi Aceh yaitu luas tutupan lahan kategori hutan mengalami penurunan dari 9490,9 Ha menjadi 6065,3 Ha, luas tutupan lahan kategori perkebunan mengalami peningkatan dari 38192,6 Ha menjadi 41385,5 Ha, begitu juga luas tutupan lahan kategori lahan terbuka/ lahan terbangun yang mengalami peningkatan dari 12834,2 Ha menjadi 13258,2 Ha. Laju deforestasi yang terjadi dari tahun 2013 sampai dengan 2021 di ekosistem gambut Rawa Tripa Provinsi Aceh yaitu 428.2 Ha/ Tahun atau 3425,6 Ha. Penyebab deforestasi yang terjadi di kawasan ekosistem gambut Rawa Tripa Provinsi Aceh adalah alih fungsi lahan hutan gambut menjadi lahan perkebunan kelapa sawit yang dilakukan oleh pemegang HGU maupun oleh masyarakat setempat.Estimating The Deforestation Rate of The Tripa Peat Swamp Ecosystem Area with A Remote Sensing Data ApproachAbstract. The Tripa Swamp peat ecosystem is one of Indonesia's peat swamp forest ecosystems. Tripa Swamp is a peat area with a depth of more than 3 meters. Under Presidential Decree No.32 of 1990, "peat forests with a depth of more than 3m are areas that must be conserved and are not allowed to be converted into agricultural land". However, this regulation cannot withstand the rate of deforestation by oil palm rights holders in the Rawa Tripa area since 1995. This study aims to analyze the rate of deforestation and find out changes in forest cover along with the area of deforestation that occurred within 8 years from 2013 to 2021 in the Tripa Swamp area. This research was conducted with remote sensing techniques using the supervised classification method, namely interactive supervised classification. The results of research with remote sensing techniques obtained the value of land cover change from 2013 to 2021 in the Rawa Tripa peat ecosystem in Aceh Province, namely the area of land cover in the forest category decreased from 9490.9 Ha to 6065.3 Ha, the area of land cover in the plantation category increased from 38192.6 Ha to 41385.5 Ha, as well as the area of land cover in the open land / built-up land category which increased from 12834.2 Ha to 13258.2 Ha. The deforestation rate from 2013 to 2021 in the Peat ecosystem of Rawa Tripa, Aceh Province, was 428.2 Ha / Year or 3425.6 Ha. The cause of deforestation that occurs in the Rawa Tripa peat ecosystem area in Aceh Province is the conversion of peat forest land into oil palm plantations carried out by HGU holders and by local communities

Abstrak. Garis pantai merupakan suatu titik pertemuan antara daratan dan lautan di pantai, yang mana garis pantai tersebut mengalami pergerakan sedimen akibat dari terjangan dan hempasan gelombang laut yang mengarah ke daratan yang membentuk gelombang pecah. Perubahan garis pantai yang diakibatkan oleh abrasi dan akresi bisa dipantau dengan menggunakan metode Visual on Screen. Adapun tujuan penelitian ini yaitu untuk memetakan perubahan garis pantai dengan metode Visual on Screen. Hasil analisis metode Visual on Screen menunjukan bahwa akresi tertinggi berada di Kecamatan Simpang Ulim sepanjang 320,53 m. Akresi yang terjadi disebabkan oleh sedimentasi Krueng Arakundo hingga munculnya tanah timbul disertai pertambahan mangrove.Kata kunci: Garis Pantai, Kabupaten Aceh Timur, Visual on Screen, Akresi.Abstract. The shoreline is a meeting point between land and sea on the coast where the shoreline experiences sediment movement due to the brunt and crash of ocean waves that lead to the land which forms breaking waves (Arief et al., 2011). Shoreline changes caused by abrasion and accretion can be monitored using the Visual on Screen method. This study aims to map changes in the shoreline using the Visual on Screen method. The Visual on Screen method analysis shows that the highest accretion is in Simpang Ulim District along 320,53 m. The sedimentation of Krueng Arakundo caused the accretion until the land appeared, accompanied by the addition of mangroves.Keywords: Shoreline, East Aceh District, Visual on Screen, Accretion

Salinity is the amount of salt contained or dissolved in water or soil. Salinity can cause the change of physical characteristics of soil, especially in coastal area, that affects human daily activities, including agriculture. Baitussalam District (Kecamatan Baitussalam) is one of the districts that was hit most devastatingly by the Indian Ocean Tsunami 2004 as well as has large population with potential agricultural prospect in Aceh Besar Region (Kabupaten Aceh Besar). This research aims to identify the soil salinity level in the Baitussalam District. The sampling technique uses descriptive methodology with scalable quantitative approach in the chosen sampling areas. 26 sampling spots have been chosen according to mathematical calculation. Quantitative method is used to analyze the result in this research. Furthermore, conductivity measurement is done through induction electromagnetic method, using Geonics EM38 and to identify the soil salinity level, analysis of soil texture is conducted in the laboratory. As the result, the electrical conductivity measurement shows varying values. The minimum conductivity value is 0,004 dS/m, taken at spot T 004 in Lam Ujong Village (Desa Lam Ujong). Whereas the maximum conductivity value reaches 10,31 dS/m, taken at spot T 003 in Labuy Village. The soil salinity in the 26 sampling spots in Baitussalam District demonstrates an average level, with a value of ECa 2-4 dS/m. The result of this research is expected to be a parameter to control and develop the activities, especially for agricultural activities, in the coastal area in Aceh Besar Region, and in Baitussalam district in particular.

This study aims to analyze land ownership in 2022, mainly in the area of Mesjid Raya District of Aceh Besar Regency. This study used a descriptive survey method. This study's results indicate that nine out of 4,208 Land Ownership Rights in the Mesjid Raya District (0.225%) have buildings on them. Therefore, the issuance of Land Ownership Certificates in Coastal Border Areas violates laws according to Government Regulation No. 16 of 2004 and Circular Letter No.4 SE-100.PG.01.01/II/2022 regarding Land Use Policy in Protected Areas. The nine types of Land Ownership Rights issued in the Coastal Border Areas are divided into four certificates of Ownership Rights and five certificates of Usage Rights, and they are located in several villages, such as two certificates in Neuheun, two certificates in Ladong, two certificates in Ruyung, one certificate in Meunasah Keudee and one certificate in Lamreh. The total area of the Ownership Rights Certificates issued in the Coastal Border Areas is 21,206 m2, and the total area of the Usage Rights Certificates is 145,302 m2.
