Abstrak. Pulau Bunta menjadi salah satu kawasan dengan kerusakan terparah pasca bencana tsunami, hingga merusak semua bangunan pemukiman warga, fasilitas seperti dermaga dan jalan, serta lahan perkebunan warga dan sebagian vegetasi hutan pesisir. Pasca tsunami lahan di Pulau Bunta yang terkena bencana perlahan dilakukan rehabilitasi kembali. Pemanfaatan lahan tersebut dipengaruhi oleh kondisi alamiah maupun kebijakan Pemerintah terkait dengan potensi yang ada, termasuk pemanfaatan lahan pada kawasan pulau-pulau kecil seperti halnya Pulau Bunta. Adapun perencanaan tata guna lahan pada kawasan pulau-pulau kecil diatur dalam Pasal 27 ayat (2) UU No. 27 Tahun 2007 tentang Pengelolaan Wilayah Pesisir dan Pulau-Pulau Kecil (Peraturan Pemerintah Republik Indonesia, 2010). Perubahan pada tata guna lahan Pulau Bunta dapat diamati dengan metode digitasi visual on screen terhadap peta Pulau Bunta tahun 2005 dan 2019. Hasil deskripsi digitasi peta Pulau Bunta tahun 2005 dan 2019 menunjukkan terdapat banyak perubahan dari kerusakan semua bangunan dan vegetasi pada tahun 2005 hingga terdapat rumah-rumah warga, kantor desa, beberapa fasilitas seperti balai, toilet umum, dermaga, bangunan pembangkit listrik tenaga surya (PLTS), serta vegetasi Pulau Bunta yang sudah banyak berkembang sesuai dengan formasi vegetasi pantai berpasir.Kata kunci: Pulau Bunta, Penggunaan lahan, Tsunami. Land Use Changes in 2005/2019 after the Tsunami on Case Study at Bunta IslandAbstract. Bunta Island became one of the areas with the most severe damage after the tsunami, to damage all residential buildings, facilities such as docks and roads, as well as residents' plantations and some coastal forest vegetation. After the tsunami the land on the affected island of Bunta was slowly rehabilitated. Land use is influenced by natural conditions and government policies related to existing potential, including land use in small island areas such as Bunta Island. The land use planning in the area of small islands is regulated in Article 27 paragraph (2) of Law no. 27 of 2007 concerning Management of Coastal Areas and Small Islands (Government Regulation of the Republic of Indonesia, 2010). Changes to the land use of Bunta Island can be observed by visual digitizing method on the map of Bunta Island in 2005 and 2019. The results of the digitization map of Bunta Island in 2005 and 2019 show that there are many changes from damage to all buildings and vegetation in 2005 until there are houses residents' houses, village offices, several facilities such as halls, public toilets, jetties, solar power building (PLTS), and vegetation of Bunta Island which has developed in accordance with the formation of sandy beach vegetation.

Abstrak. Garis pantai merupakan batas antara air laut dan daratan. Batas ini selalu berubah dengan sangat dinamis dan saling berintersaksi, perubahan secara sementara seperti adanya pasang surut maupun perubahan akibat abrasi dan akresi dalam kurun waktu yang lama. Perubahan garis pantai disebabkan oleh proses alami maupun aktivitas manusia dalam memanfaatkan kawasan pantai guna memenuhi kebutuhannya (Niya, et al., 2013). Adapun tujuan penelitian ini yaitu untuk mengetahui terjadinya perubahan garis pantai, lebar perubahan garis pantai dan faktor penyebabnya. Analisis perubahan garis pantai diawali dengan pengumpulan data skunder, yaitu data citra landsat 5, 7 dan 8. Kemudian dilanjutkan dengan analisis menggunakan tools Digital Shoreline Analysis System (DSAS). Hasil analisis menunjukan bahwa terjadi perubahan garis pantai dalam kurun waktu 20 tahun terakhir. Sebagian besar perubahan garis pantai mengalami abrasi dan hanya sebagian kecil yang mengalami akresi. Abrasi terjadi secara alami disebabkan oleh energi kinetik air laut sedangkan akresi terjadi di kawasan terbangun, yaitu pembangunan infrastruktur seperti di pelabuhan, dermaga dan kawasan-kawasan yang dibangun Seawall.Abstract. The coastline is the boundary between sea water and land. This boundary is always changing very dynamically and interacting with each other, temporary changes such as tides and changes due to abrasion and accretion over a long period of time. Changes in coastlines are caused by natural processes and human activities in utilizing coastal areas to meet their needs (Niya, et al., 2013). The purpose of this study is to determine the occurrence of shoreline changes, the width of shoreline changes and the factors causing it. The analysis of shoreline changes begins with the collection of secondary data, namely Landsat 5, 7 and 8 imagery. Then proceed with analysis using the Digital Shoreline Analysis System (DSAS) tools. The results of the analysis show that there has been a change in the coastline in the last 20 years. Most of the changes in the shoreline undergo abrasion and only a small part undergoes accretion. Abrasion occurs naturally due to the kinetic energy of seawater while accretion occurs in built-up areas, namely infrastructure development such as ports, docks and areas built by Seawall.

Bener Meriah Regency is one of the Arabica coffee producing areas in Aceh Province. Arabica coffee can generally grow optimally at altitudes above 800 m above sea level. The average productivity of Arabica coffee in Bener Meriah Regency is not optimal, which ranges from 600-800 kg/ha/year. The research aims to determine the relationship between land characteristics and Arabica coffee production. The method used in this study was a field survey to obtain data on land characteristics in Bener Meriah Regency. The observation site was determined based on the SST formed by overlaying a map of soil type, altitude, slope and map of existing coffee plantations in Bener Meriah Regency. Land suitability for Arabica coffee was obtained by comparing land characteristic data obtained in the field with the requirements for growing Arabica coffee belonging to Pujianto (1991). Arabica coffee production data was obtained by means of production estimation, namely counting the number of red spindles on the sample coffee plants. To obtain data on the relationship between land characteristics and production, multiple linear regression analysis was performed. The results showed that the Arabica coffee land suitability classes in Bener Meriah Regency were S3 (suitable marginal) with limiting factors for lack of nutrients such as C-Organic, P-available and N-total and steep slopes. The average Arabica coffee production is 828.85 kg/ha of net beans. The results of the multiple linear regression analysis between land characteristics and production showed a very strong value of 0.857.

Arbuscular Mycorrhizal Fungi (AMF) is a type of fungus that is capable of mutualistic symbiosis with plant roots. The presence of AMF can increase the availability of nutrients in the soil, especially the element P, expand the nutrient uptake area with the help of mycelium, plant resistance to disease and drought, and be able to produce growth hormones. These fungi can form a symbiotic relationship and increase the growth and productivity of coffee plants. This research aims to multiply AMF spores collected from the rhizosphere of Arabica coffee plants in Bener Meriah Regency using corn as a host plant. This research uses a descriptive method. Propagation of AMF spores collected from the rhizosphere of Arabica coffee plants using a single propagation method using zeolite media and corn host plants. Counting of AMF spores resulting from multiplication and observing AMF colonization on plant roots was carried out after the corn plants were stressed. Observation of the number of spores was carried out using the wet filtration isolation method and centrifugation technique (Brundrett et al., 1996). Observation of the percentage of AMF colonization on corn plant roots using the root staining method. Data analysis was carried out descriptively. The research results showed that from 44 AMF spores originating from the rhizosphere of Arabica coffee in Bener Meriah Regency, 111 AMF spores were obtained from propagation with a colonization percentage ranging from 0 – 81%. The largest number of spores were 11 spores resulting from multiplication originating from M44 spores, while the highest percentage of root colonization (81%) with very high criteria contained host roots colonized by M1 spores. A total of 12 AMF spores colonized the host roots with high to very high criteria. The research results showed that AMF spores from the rhizosphere of Arabica coffee in Bener Meriah Regency which were propagated by pot culture on zeolite media and corn as the host plant were relatively low with the percentage of root colonization varying from none to very high
