Abstract

Abstract. Vegetation index values derived from the  Landsat-8 OLI images have been used widely to assess plant growth, especially in oil palm plantations. This study intends to estimate growth rates and establish the phenology of oil palm growth based on spectral reflection patterns. This study employed multitemporal Landsat-8 OLI images from 2013, 2014, 2017, 2020, and 2021 to visually interpret satellite imagery based on spatial and digital detection of object attributes. The phenology of oil palm growth is grouped into the Seed-0 Phase (0-1 Years), Seed Phase (1-3 Years), Young Phase (4-8 years), Teenage Phase (9-14 years), Mature Phase (15-20 years) and Old Phase ( 20 years). The results of the digital analysis of Landsat 8 OLI show that the spectral reflection pattern has almost the same shape at the same wavelength and varies in each phase of oil palm growth. The average NDVI vegetation index value shows a green peak in the teenage phase (0.908). The results of a simple linear regression averaging the NDVI vegetation index value with the average age data of each oil palm growth phase from the TBM-0 phase (0-1 year) to the old phase ( 20 years) yields a moderate relationship for the transformation of the vegetation index NDVI. The transformation of the NDVI vegetation index produces an R² with a value of 0.483 that the regression results formed above the adolescent phase (9-13 years) do not form a pattern

Abstract: One of the area of priority for the slum area handling is Sabang City, Aceh province. The Slum areas in Sabang that will be reviewed are the village of Cot Bak U. The villages have obtained the handling project by Ministry of Pubic Work, Department of Development of Settlement Area, Aceh Province, conducted by 2016 through the construction of roads and Environmental drainage. This study aims to evaluate this project. The Research methods are quantitative and comparative approaches by calculating the data towards these two criteria after treatment and compare it with baseline data. Based on the results of the research can be concluded that the slums handling project towards these 2 (two) criteria does not give major change to value level of slums. For Cot Bak U village the point turn to 29 of 31 with a difference of 2 points. The results of this research indicated that the handling still needs to be implemented towards both slum areas. Moreover also need to conduct periodic evaluation of the value towards the slum area which has been assigned to find out the changes that occur as well as involving local communities in the maintenance of the quality of the neighborhoods, so that the expected value will be increased.Abstrak: Salah satu daerah yang mendapatkan prioritas untuk penangan area kumuh adalah Kota Sabang, Provinsi Aceh. Kawasan kumuh di Kota Sabang yang akan ditinjau adalah desa Cot Bak. Desa ini telah mendapatkan penanganan kumuh oleh Kementerian PU Satker Pengembangan Kawasan Permukiman Provinsi Aceh yang dilakukan pada tahun 2016 melalui pembangunan Jalan Lingkungan dan Drainase Lingkungan. Penelitian ini bertujuan untuk mengevaluasi pembangunan jalan dan drainase lingkungan. Metode penelitian dilakukan secara kuantitatif dan komparatif yaitu melalui perhitungan data terhadap 2 (dua) kriteria setelah penanganan dan perbandingannya dengan data baseline. Berdasarkan hasil penelitian dapat diketahui bahwa penanganan kawasan kumuh terhadap 2 (dua) kriteria kekumuhan yang telah dilaksanakan di kedua kawasan kumuh tersebut tidak memberikan perubahan yang besar terhadap nilai kekumuhan yaitu untuk kawasan Cot Bak U sebelum penanganan sebesar 31 menjadi 29 dengan selisih sebesar 2 point. Hasil penelitian ini menunjukkan bahwa masih perlu dilakukannya penanganan terhadap kedua kawasan kumuh ini. Salain itu juga perlu dilakukan evaluasi nilai kekumuhan secara berkala terhadap kawasan kumuh yang telah ditetapkan untuk mengetahui perubahan yang terjadi serta melibatkan masyarakat setempat dalam pemeliharaan kualitas permukiman, sehingga diharapkan nilai kekumuhan yang ada tidak mengalami penurunan namun mengalami peningkatan.

Abstract

Abstract:Spatial planning of Langsa City is still required in order to realize clean city, neat and beautiful. Spatial planning can also improve performance of drainage channels so that flood and inundation do not occur. Gampong Teungoh village and Gampong Baru village is an area of development and entrance Langsa City from the east, that still occur floods and inundation of up to 0.3-0.5 m so that performance improvement of drainage channels is required. Drainage channel performance is good if the dimensions of channels enough to drain rainwater runoff.  Drainage performance was evaluated before and after spatial planning is done by comparing discharge or capacity of channel with discharge of flood design of rainwater runoff. Spatial planning is done by providing a green space area of 10 % of the land area of residential parcels, maintain the function of public green space that has been there, and make a parking lot out of the water absorptive material. After spatial planning is done, runoff coefficient decreased from 0.45-084 to 0.4-0.75 so that discharge of flood design of rainwater runoff also decreased. This is causes channel performance previously not good to be good. Then decreasing of this discharge also caused available of remaining land due to channel dimensions that smaller than before. In this remaining land was used as a green line that can reduce the value of the runoff coefficient and then reduce discharge of rainwater runoff, and ultimately may also impact the performance improvement of drainage channels.Keywords : spatial planning, performance, drainage channel, green space area, runoff coefficient, discharge storm water runoff.Abstrak:Penataan ruang Kota Langsa masih diperlukan demi mewujudkan kota yang bersih, rapi dan indah. Penataan ruang yang baik dapat juga meningkatkan kinerja saluran drainase sehingga banjir dan genangan tidak terjadi. Desa Gampong Teungoh dan Gampong Baru merupakan kawasan pengembangan dan kawasan entrance Kota Langsa dari arah Timur, yang . masih mengalami banjir dan genangan hingga mencapai 0,3-0,5 m sehingga diperlukan peningkatan kinerja saluran drainase agar banjir genangan tersebut tidak terjadi. Kinerja saluran drainase dikatakan baik jika dimensi saluran cukup untuk mengalirkan debit rencana limpasan air hujan. Kinerja saluran drainase dievaluasi sebelum dan sesudah penataan ruang dilakukan dengan membanding debit saluran dengan debit rencana. Penataan ruang dilakukan dengan menyediakan ruang terbuka hijau seluas 10% dari luas tanah persil rumah tinggal, tetap mempertahankan fungsi ruang terbuka hijau umum yang telah ada, dan membuat lahan parkir dari bahan serap air. Setelah penataan ruang, nilai koefisien aliran menurun dari 0,45-084 menjadi 0,4-0,75 sehingga debit rencana aliran limpasan air hujan juga menurun. Penurunan debit ini menyebabkan kinerja saluran yang sebelumnya tidak baik menjadi baik. Kemudian penurunan debit ini juga menyebabkan adanya sisa lahan akibat pengecilan dimensi saluran. Pada sisa lahan ini dijadikan jalur hijau yang dapat memperkecil nilai koefisien aliran dan kemudian memperkecil debit aliran limpasan air hujan, dan akhirnya dapat pula berdampak kepada peningkatan kinerja saluran drainase.

Abstract

Heavy metal pollution is one of the problems that often occurs in Indonesian coastal waters. Comparative methods of looking at heavy metal content in coastal sediments include a way to show similarities and differences between one or more articles by using certain criteria. Different comparison methods to see the heavy metal content in sediments include the AAS (Atomic Absorption Spectrophotometer) method, AAN (Netron Activation Analysis), Regression, and USEPA methods. Based on the comparison of 2 methods, namely: AAS and AAN methods, the most efficient in analyzing heavy metals in sediments in coastal areas is the Atomic Absorption Spectrophotometry (AAS) method compared to the Neutron Activation Analysis (AAS) method.Keywords:CoastalSedimentHeavy MetalSpectrophotometer

Abstract

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

Abstract

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
