    Abstract

    ABSTRACT Dominikus Victorius Bate, Risk Analysis And Mitigation of Landslide In Cibal District, Manggarai Regency, East Nusa Tenggara. Thesis. Supervisor I : Puguh Karyanto, S.Si, M.Si, Ph.D. Supervisor II : Dr. Moh. Gamal Rindarjono, M.Si. Program Study of PKLH , Faculty of Teacher Training and Education Sebelas Maret University Surakarta. The research aims to determine (1) the level of landslide danger, (2) landslide vulnerability, (3) landslide risk, and (4) mitigation to reduce the risk of landslide in Cibal District of Manggarai Regency in Nusa Tenggara Timur. The method in this research is survey method. The Population used is landuse in Cibal District. Collecting Sampling technique uses the way of sample saturation, the technique is the number of samples taken equal to the number of population. Data collecting techniques uses observation and documentation study. Data analysis techniques to determine the danger level by scoring, while to determine the level of susceptibility by crosstab. Landslide risk analysis uses crosstab by linking the danger and landslide susceptibility, while disaster mitigation is based on the risk of landslides. The results shows that there are three classes of landslide danger. They are low, medium, and high. (1) Low landslide danger is found in 20 land units covering 1.112,31 ha or 10,21%, the level of medium landslides is in 55 land units covering 4.593,79 ha or 42,18%, while the level of landslides is high. there are 56 units of land area of ​​5.183,86 ha or 47,61%. (2) Low landslide is found in nine villages, the medium susceptibility of landslides is found in seven villages, while the susceptibility of high landslides is only found in one village. In Cibal District, Manggarai Regency, It has three classes of landslide risks. They are low, medium, and high. (3) Low landslide risk is found in 70 land units with an area of ​​3.904,72 ha or 35,86%, the risk of medium landslides is in 120 land units with an area of ​​6.802,24 ha or 62,46%, and the risk of high landslides is found in 18 land units with an area of ​​183,01 ha or 1,68%. (4) For landslide mitigation direction in this study only selected for locations that have a moderate and high risk of landslides. Direction for decreasing landslide danger include vegetative prevention, civil engineering and social engineering. Key Words : Landslide, Danger, Susceptibility, Risk, Migitation.
