Abstract

ABSTRAKPengolahan tanah intensif yang bertujuan untuk membersihkan gulma dan menciptakan media tumbuh yang gembur pada lahan berlereng menyebabkan tertutupnya pori-pori tanah dan menghambat proses infiltrasi. Proses infiltrasi yang terhambat dapat memicu terjadinya erosi. Pemberian bahan organik (kompos) diharapkan untuk memperbesar kapasitas infiltrasi sehingga dapat mengurangi erosi. Penelitian ini bertujuan untuk mengetahui berapa besar erosi dan infiltrasi yang terjadi pada lahan hortikultura yang berlereng. Penelitian ini dilakukan di lapangan menggunakan metode petak kecil. Hasil penelitian rata-rata erosi yang terjadi pada lahan hortikultura berlereng pada petak teras guludan dengan kompos yaitu 6,54 ton/ha/tahun dan petak guludan tanpa kompos yaitu 4,45 ton/ha/thn. Rata-rata infiltrasi pada lahan hortikultura berlereng dengan perlakuan guludan tanpa kompos lebih tinggi (222552,01 mm/jam) dibandingkan dengan infiltrasi pada lahan hortikultura dengan perlakuan teras guludan dengan kompos (41464 mm/jam).Kata kunci : Erosi, Infiltrasi, Lereng

Abstract

AbstractThe objective this study was to predict erosion rate and erosion hazard level in DumogaSub-watershed. The study is expected to provide spatial information on erosion rateand erosion hazard level in Dumoga Sub-watershed, particularly for spatial planning as wellas soil and water conservation. Erosion was predicted employing USLE while spatial analysiswas conducted using Geographic Information Systems (ArcView 3.3). Rainfall data were collectedfrom three weather stations, erodibility values obtained by analyzing samples fromthree soil types, slope categories were determined using DEM (Digital Elevation Model), valuesof the landuse and soil conservation were determined by means of satellite image interpretationin and field survey as well. It was found that soil erosion ranged from 0.39 to16.800 tonnes /ha/year. The lowest erosion rate occurred on forest land and ricefield withhacingflatslope. The highest erosion rate was identified on farm land having very steep slope.Erosion hazard level varied from verylow to very severe. It is necessary to perform soil andwater conservation measured on the land experiencing severe to very severe erosion hazardas to reduce soil erosion.Keywords: Erosion, Geographic Information System, Watersheed

Abstract

sistem informasi geografis.ABSTRACThis study was conducted during one month (May 29, - June 29, 2014) andimplemented in the city of Manado. This study aims to analyze the flood prone areas in thecity of Manado in order to obtain the level of vulnerability and dissemination of informationin the form of a map by using a Geographic Information System. The study was conducted byusing descriptive method which consists of collecting data and map overlay. While theidentification of flood-prone areas using the method by Hematang (2011). Parametersmeasured were soil type, slope, land use and rainfall. The results of this study show the studyarea prone to flooding in the city of Manado has not vulnerable flood level (an area of603.34 ha), the vulnerability of being (an area of 5467.01 ha), are not susceptible (coveringan area of 6492.39 ha) and the rate is very susceptible (an area of 2180.11 ha) spread in 10districts namely Bunaken, Malalayang, Mapanget, Sario, Singkil, Paal Dua, Tikala,Tuminting, Wanea and Wenang.Key Word : mapping, flood, geographic information system

Abstract

ABSTRACTThe purpose of this study was to determine the land suitability for areca nut (Areca catechu) in Remu watershed, Sorong, West Papua Province. This research uses descriptive method comprising of survey and map overlay. This research was conducted in the field and the GIS laboratory, Faculty of Agriculture, University of Sam Ratulangi. The research was conducted during ± 4 months, namely from January to April 2015. It was revealed that within 5771.74 ha of suitable area, 2581.76 ha area was classified as the most suitable, 898.7 ha as fairly suitable, and 1730.57 ha as marginally suitable. In addition, 509.78 ha area was evaluated as presently not-suitable and 50.93 ha as permanently not suitable. Further study is required as to provide more specific site information on land suitability for areca nut in the study area.Keywords : GIS, land suitability, areca nut

Abstract

ABSTRACT The purpose of this study was to determine the level of nutrient availability, N P and K around corn plants. The results of this study found that the element of nitrogen in the soil around the roots showed relatively low. The element of phosphorus around the roots is moderate and the phosphorus in the soil around the mixed roots is moderate. The element of potassium around the roots is low to high and tanh around the roots are mixed, the potassium content is above the potassium deficiency.
