Abstract

Land cover will change due to population pressure, resource use, and human interest in space. Measuring the land area is important to determine how much-converted land is positive and negative. The vegetation on land was determined by how densely the plants were spread out. This study is conducted in Palabuhanratu, Sukabumi Regency. Aims to test and compare how accurate EVI and SAVI are at seeing vegetation density. The images used are from Landsat 8 in 2018 and 2022. Calibration is performed using high-resolution images, followed by field surveys with 98 points from polygon sampling. The average accuracy of the results from EVI is 49%, while the average accuracy of the results from SAVI is 45%. So, we can say that the EVI or SAVI based-input gives a similar result on observing the vegetation density in Palabuhanratu.

Abstract

A landslide is a disaster that often occurs in Indonesia, especially in morphology that has rough topography. This disaster is caused by faults, natural factors such as rainfall, topography, soil type, rock type, and human activity factors such as changes in land covered by a land cover or other factors related to landslide triggers. This research is located in the northern part of the Cianjur residency, this area is located between active volcanic mountains which have a distribution of sedimentary rocks and volcanic rocks, which are included in the Bandung physiographic zone, and have the new Cugenang fault. The unit of analysis is districts, which consist of 10 sub-districts. The purpose of this study was to analyze the landslide hazard distribution in the northern part of the Cianjur regency. The study used a sptial approach by using the weight overlay method for all parameters that have previously been analyzed and interpolated. The results of this study are very high Susceptibility covering 0.06%, high Susceptibility 47.49%, moderate Susceptibility 52%, and low Susceptibility 0.01%. The most vulnerable area is Sukaresmi, and the sub-district with moderate Susceptibility is Cikalong Kulon, while the low and high Susceptibility is relatively scattered in all areas with a small percentage. Based on the parameters analyzed, it means that rainfall and slope are the dominant driving factors in landslide Susceptibility in the northern part of the Cianjur regency because they have a large weight. This study provides a classification related to landslide susceptibility mapping in the northern part of Cianjur.
