ZONASI KERENTANAN LONGSOR DENGAN METODE ANALYTICAL HIERARCHY PROCESS (AHP) DI DAS JLANTAH HULU KABUPATEN KARANGANYAR TAHUN 2014

Abstract

ABSTRACT

This study is aimed to (1) know about the landslide zonation in Jlantah Upperland Karanganyar Regency 2014, (2) know the type of landslide in Jlantah Upperland Karanganyar Regency 2014, (3) know some mitigation steps for landlisdes phenomenons in Jlantah Upperland Karanganyar Regency 2014, (4) make an implementation On A Base Competencies For Analyzed Relationship Between Human and Environment As A Result Of Pedosfer and Lytosfer Dynamics at Main Principal on The Effect of Exogens For Humanity Process : For a Senior High School Grade X.
This study use descriptive method with landunit as the unit analysis and organized with survey on a fields. Landunit are part of the land with similar land characteristics of geology, soils, slope and land use. Overlaying of these characteristics produced The Landunit Map, consist of 28 landunits, which the main study populations. Sampling Techniques with purposive sampling. Data collecting in this study done by field observations, interviews, laboratory test and documentation anlysis. Data Analysis Techniques with a qualitatives analysis with Analytical Hierarrchy Process (AHP) to get the vulnerability of landslide zonation in Jlantah Upperland, analyzed landlslide types with field observations to make mitigation steps of landlside phenomenons with the type of landslided on Jlantah Upperland.
Based on data analysis, the conclusion of this research are : (1) Jlantah Upperland has 3 classes of vulnerabilities landslide, non vulnerable lanslide class, semi vulnerable landlside class and vulnerable landslide class, (2) Jlantah Upperland has 3 type of landslides, there was a translation landslide, debris avalances and earth flows, (3) The mitigation steps done by tehniqal ways and vegetational ways based on identified landslide types in Jlantah Upperland, (4) Final results of this research could use for Geographics Studies Media at Main Principal on The Effect of Exogens For Humanity Process : For a Senior High School Grade X.
