Abstak. Kekeringan terjadi akibat dari distribusi hujan yang hujan yang tidak merata. Kekeringan menyebabkan kerugian baik dalam bidang pertanian maupun non pertanian. Kekeringan menempati peringkat kedua bencana yang paling sering terjadi di Aceh. Salah satu metode yang dapat digunakan dalam menganalisa dan merepresentasikan tingkat kekeringan suatu wilayah adalah metode indeks kekeringan SPI (Standardized Precipitation Index). Penelitian ini bertujuan untuk mengetahui sebaran kekeringan di wilayah pesisir Timur Aceh. Data curah hujan diperoleh dari empat stasiun penakar hujan yaitu: Stasiun Meteorologi Malikussaleh, Pos Hujan Idi Rayeuk, Pos Hujan Langsa Barat dan Pos Hujan Bandar Pusaka. Penilaian indeks SPI dilakukan dengan menganalisis data curah hujan bulanan pada pos hujan kajian, analisis dilakukan pada periode 30 tahun yaitu dari tahun 1991 sampai 2020. Hasil analisis indeks kekeringan SPI di wilayah pesisir Timur Aceh menunjukkan adanya terjadi kekeringan dengan kondisi yang bervariasi, mulai dari kondisi kering, sangat kering dan amat sangat kering. Kondisi kekeringan pada tahun 2015, 2018, 2019 dan 2020 merupakan tahun terparah terjadinya kekeringan di lokasi kajian. Sebelum tahun 2015 kekeringan terparah terjadi dalam kurun waktu 3-4 tahun sekali, namun setelah tahun 2018 kekeringan terparah terjadi dalam kurun waktu setahun sekali, sehingga dapat diketahui ada kemungkinan terjadi kekeringan kembali di wilayah pesisir Timur Aceh di masa yang akan datang.Drought Distribution Assessment in East Coast of Aceh Using Standardized Precipitation Index (SPI) and Geographical Information System (GIS) MethodsAbstract. Drought occurs as a result of the uneven distribution of rain. Drought causes losses in both agriculture and non-agriculture. Drought is the second most frequent disaster in Aceh. One method that can be used to analyze and represent the level of drought in an area is the SPI (Standardized Precipitation Index) drought index method. This study aims to determine the distribution of drought on the East coast of Aceh. Rainfall data were obtained from four rain gauge stations, namely: Malikussaleh Meteorological Station, Idi Rayeuk Rain Post, Langsa Barat Rain Post, and Bandar Pusaka Rain Post. The SPI index assessment was carried out by analyzing monthly rainfall data at the study rain post, the analysis was carried out over 30 years, namely from 1991 to 2020. The results of the SPI drought index analysis in the East coast of Aceh showed that there was a drought with varying conditions, ranging from moderate drought, severe drought, and extreme drought. Drought conditions in 2015, 2018, 2019, and 2020 were the worst years of drought in the study location. Before 2015 the worst drought occurred every 3-4 years, but after 2018 the worst drought occurred once a year, so it can be seen that there is a possibility of another drought on the East coast of Aceh in the future.

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

The use of Geographic Information Systems (GIS) to generate digital data that provides information on the characteristics of an area and describes changes in land cover that can be used in a more effective and efficient sustainable manner. This study aims to analyze the mangrove land cover of the north coast of Aceh Besar over the last three decades, namely 2000, 2010, and 2020 in the Baitussalam sub-district, Mesjid Raya sub-district and Seulimeum sub-district. The research was conducted from June 2022 to September 2022 at the GIS Laboratory, Faculty of Marine and Fisheries, Syiah Kuala University. The research was conducted using a Geographic Information System (GIS) that utilizes high-resolution satellite imagery from Google Earth Pro. Mangrove land was digitized visually on screen, then data processing was carried out, and spatially analyzed. The results of the analysis of changes in mangrove land cover in the research area show that the Baitussalam and Mesjid Raya sub-districts had a decreasing trend of mangove land between 2000 and 2010 and subsequently there was an increase in mangrove land cover from 2010 to 2020. Meanwhile, Seulimeum sub-district experienced a decreasing trend of land cover in 2000 until 2020. The decline in the trend of mangroves in various places is caused by the growth of the population using mangrove land as residential area. While the increase in mangove land cover was due to the success of reforestation and pond land conversion. The results conclude that the mangrove land cover on the north coast of Aceh Besar is relatively stable with an increasing trend of growth.Keywords:Land coverMangroveHigh resolution googleHistorical imageryGoogle earth proDigitize

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.
