PEMBUATAN PETA SITUASI SKALA 1 : 500 LOKASI 1, DUSUN KALICANGAK DAN BABADAN, DESA BELUK, KECAMATAN BAYAT, KABUPATEN KLATEN, PROPINSI JAWA TENGAH

Job Training Activity (PKL) is an annual eventof geomatics courses that has to be followed by every student as the final evaluation, the basics knowledge usedin the Job Training Activity have been given duringthe lecture. Work performed in planimetris are mapping situation.Mapping the situationis a form of mapping which includes planimetric and contour measurement. Initial measurements of the mapping work is the making of the basicpoints of the mapping framework (TKDP) were fairly evenly in the area to be mapped using a total station theodolite measuring instrument and a carpenter's level. This TKDP will be abond of details that are the object of the elements that exist on the surface of the earth which will be illustrated in the map. The depiction of the map manuscript is described using Surpac software that is then used for testing the map, while themap depiction of the situation carried out using ArcGIS software. The end result of the activities of the Job TrainingActivity is a situation map scale of 1: 500 and printed on A1 size paper and can present spatial information in the region

Gully morphology, hillslope erosion, and precipitation characteristics in the Appalachian Valley and Ridge province, southeastern USA

This study investigates gully erosion on an east Tennessee hillslope in a humid subtropical climate. The study area is deeply gullied in Ultisols (Acrisol, according to the World Reference Base for Soil), with thirty years of undisturbed erosional history with no efforts to correct or halt the erosion. The objectives are (1) to examine how different gully morphologies (channel, sidewall, and interfluve) behave in response to precipitation-driven erosion, and (2) to identify an appropriate temporal scale at which precipitation-driven erosion can be measured to improve soil loss prediction. Precipitation parameters (total accumulation, duration, average intensity, maximum intensity) extracted from data collected at an on-site weather station were statistically correlated with erosion data. Erosion data were collected from erosion pins installed in four gully systems at 78 locations spanning three different morphological settings: interfluves, channels, and sidewalls. Kruskal-Wallis non-parametric tests and Mann-Whitney U-tests indicated that different morphological settings within the gully system responded differently to precipitation (p\u3c0.00). For channels and sidewalls, regression models relating erosion and precipitation parameters retained antecedent precipitation and precipitation accumulation or duration (R2=0.50, p\u3c0.00 for channels, R2=0.28, p\u3c0.00 for sidewalls) but precipitation intensity variables were not retained in the models. For interfluves, less than 20% of variability in erosion data could be explained by precipitation parameters. Precipitation duration and accumulation (including antecedent precipitation accumulation) were more important than precipitation intensity in initiating and propagating erosion in this geomorphic and climatic setting, but other factors including mass wasting and eolian erosion are likely contributors to erosion. High correlation coefficients between aggregate precipitation parameters and erosion indicate that a suitable temporal scale to relate precipitation to soil erosion is the synoptic time-scale. This scale captures natural precipitation cycles and corresponding measurable soil erosion
