Abstrak.Infiltrasi adalah aliran air secara vertikal ke dalam tanah melalui permukaan tanah. Kapasitas infiltrasi adalah kemampuan tanah dalam merembeskan banyaknya air ke dalam tanah. Kapasitas infiltrasi tanah yang rendah, akan menyebabkan sebagian besar curah hujan yang jatuh pada suatu daerah akan menjadi genangan di permukaan tanah dan mengalir menjadi aliran permukaan hingga hanya sebagian kecil yang masuk ke dalam tanah yang menjadi simpanan air tanah. Efeknya pada musim penghujan kemungkinan terjadi banjir dan pada musim kemarau akan terjadi kekeringan. Sebaliknya kapasitas infiltrasi tanah yang tinggi juga akan merugikan karena dapat menurunkan produktivitas lahan pertanian karena dapat menyebabkan meningkatnya proses pencucian unsur hara tanah. Penelitian ini bertujuan untuk mengetahui pengaruh karakteistik sifat fisika tanah tehadap kapasitas infiltrasi di Kecamatan Syiah Kuala Kota Banda Aceh. Penelitian ini dilakukan di Kecamatan Syiah Kuala, Kota Banda Aceh dengan melakukan pengamatan langsung di lapangan. Hasil penelitian menunjukkan bahwa kapasitas infiltrasi yaitu berada pada kriteria lambat (0,1-0,5), agak lambat (0,5-2,0) dan sangat lambat (0,1) cm/menitPhysical Characteritics of Soil Towards Infiltration Capacity In Syiah Kuala District Banda Aceh.Abstract. Infiltration is a stream vertically into the sewers through the surface. The capacity for infiltration is the ability of the soil to rejuvenate an amount of water into the ground. This low land infiltration capacity will cause most of the rainfall that falls on an area to become a surface puddle and flow into surface streams so that only a small section of soil is deposited in a reservoir of groundwater. The effect in the rainy season is likely to occur and the dry season there will be drought. In countrast the high earth infiltration capacity will also be detrimental as lowering agricultural productivity because it can cause an increase in the land washing process. This study aims to know the influence of characteristic properties of soil physics on the infiltration capacity in syiah kuala, banda aceh. This study was conducted in the east ridge of syiah kuala, banda aceh by making direct observation in the field and its continuing with the lab analysis. Research show that the infiltration capacity will be on slow criteria (0,1-0,5), a little slow (0,5-2,0), and very slow (0,1) cm/min.

This study aims to determine the rate of erosion with a variety of cover crops and rainfall intensity using a rainfall simulator. This research is expected to provide information on the measurement of erosion rates with a variety of ground cover plants and rain intensity using a rainfall simulator, and can provide information on good ground cover plants for erosion prevention. This research was conducted on soil without ground cover plants, mini elephant grass cover plants and Japanese grass cover plants. This study used variations in rain intensity, namely the first intensity was 81.00 mm/hour with the classification of light rain, the second intensity was 305.8 mm/hour with the classification of moderate rain and the third intensity was 611.5 mm/hour with the classification of heavy rain. Soil sampling in the field in this study used erosion plots. Measurement of erosion rate and rain intensity in the laboratory in this study used a rainfall simulator. The results of measuring the highest erosion rate in this study were found in soil without cover crops with a slope of 55% and a rain intensity of 611.5 mm/hour with an amount of erosion of 50.00 tonnes/ha which is classified as low. While the lowest amount of erosion was found in mini elephant cover crops with a slope of 11% and a rain intensity of 81.0 mm/hour with an amount of 5.10 tonnes/ha which is classified as very low. The results of measuring the erosion rate of ground cover plants that are effective for erosion prevention are mini elephant grass. This is because mini elephant grass has thicker leaves and has a density compared to Japanese grass.

Bamboo chips, palm shells, and rice husks waste are environmental pollutants, but have the potential to be processed by pyrolysis to become biochar. Biochar is organic products rich in carbon, high in micro pores and very suitable for amending degraded (damaged) lands. Quality of biohar to be used as a soil amendment is highly dependent on is the raw material (feedstocks) to make biochar itself. The research objective was to find out the most suitable type of biochar to be used as a soil amendment for ex-mining land, so that the growth and production of plants can be optimum. The research has been carried out in the experimental station of the Syiah Kuala University Banda Aceh from August to December 2019 using soil from ex-excavated coal mines of PT. Mifa in West Aceh, Aceh Province. The plant parameters studied were morphological parameters of plant roots (length, weight, specific root length and ratio of roots to plant shoot), nutrient uptake of N, P, and K planted on ex-mine excavated soil. The study was designed using a non-factorial randomized block design consisting of two observation treatment factors, namely the type of biochar treatment (bamboo, palm shell, rice husk) and the dose of biochar (0, 10, 20 ton ha-1), and repeated 3 times. The observations that were observed included the components of root morphology and nutrient uptake of N, P and K plants. Biochar characteristics were analyzed using a Scanning Electron Microscope (SEM). Chemical-physical analyses of soil and plants were based on the procedure issued by the Soil Research Institute, Bogor. The effect among treatments was carried out by a variance analyses test (ANOVA) and if there was an effect, the honestly difference test (Tuckey-HSD) was continued at the level of 0.05. The results showed that the type of biochar had a significant effect on root morphology and nutrient uptake of N, P and K plants. Application biochar of rice husk with the amount of 20 tons ha-1 showed the best treatment for all the parameters studied, this is because nitrogen content in rice husk biochar contribute to growing corn crop. This study also found that bamboo biochar and palm shells gave a negative response when the amount of administration was increased to 20 tonnes ha-1 except for rice husk biochar.

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
