Samigaluh Subdistrict in Kulon Progo Regency, Yogyakarta, is prone to landslides. The objective of this study is to determine the subsurface lithology in the land movement zone. The research was conducted using the Schlumberger configuration geoelectric method. Measurements were carried out deploying six lines with line lengths ranging from 100 to 150 m. The results identified a vertical distribution of subsurface rock resistivity values to a depth of 74.05 m with a value of 0.06-13749.51 Ωm. The lithology consists of soil (14.18-361.23 Ωm), clay (0.06-42.73 Ωm), sandstone (0.35-123.44 Ωm), conglomerate (1372.7-10168.66 Ωm), and andesite 13749.51 Ωm. Damage to buildings and roads were found around the formation boundary where the damage is located in the Kebobutak formation.

consumption of instant noodles from Korea, namely Samyang noodles, which is a country with a non-Muslim majority population, there are issues circulating regarding the halalness of Samyang noodle products which are considered to contain pork oil. This research aims to examine how the halal label factor influences buyer preferences, especially in the Kerinci area. The author uses quantitative research with a descriptive approach. In the research used as primary data were answers to questionnaires submitted to the people of Kerinci Regency. Meanwhile, secondary data is in the form of library literature, notes or historical reports that have been compiled in archives (documentary data) such as the Purchase Decision for Samyang Noodles in Generation Z, and processed using certain statistical methods. The scope of this research focuses more on variables that influence purchasing decision preferences. on imported food products. The influencing variables are halal labeling, income and product price. The results of this research are that the halal label variable has a significant effect on the decision to choose because the t-count value of ttable or 3.652, 199495 and the resulting significance is 0.001 - 0.05. So this means that the halal label variable has a significant effect on the decision to choose. "The halal label variable has a positive influence on the decision to choose teenagers from Kerinci Regency" is accepted. Meanwhile, the price variable does not have a significant effect on the decision to choose because the value of tcount or 1.718 1.99495 and the resulting significance is 0.90 0.05. So this means that the price variable does not have a significant effect on choosing decisions. "The price variable does not have a positive influence on the decision to choose teenagers from Kerinci Regency" and the percentage of influence between variables X1 and X2 on variable Y is 19.2%

The landslide in Kalongan Village affected an area of 5 hectares and has the potential to experience further landslides. Landslides can occur with triggers of external factors such as earthquakes. The Peak Ground Acceleration (PGA) parameter can represent the impacts that occur on the surface in the form of earthquake intensity (MMI). Kalongan Village is 25.5km from the epicenter of the Ambarawa earthquake on 27 May 2023. This study aims to modeling the PGA microzonation and the intensity of the Ambarawa earthquake in the avalanche zone in Kalongan Village. The PGA model is based on measurements of 72 microtremor data in the avalanche zone using the Kanai method. Parameters of the Ambarawa earthquake with a magnitude of 2.5 and a depth of 5 km. The results of PGA modeling in the avalanche zone varied between 1.0-7.1 gal or I-II MMI values. The results of the PGA modeling show that aftershocks can occur if the strength of the Ambarawa earthquake reaches M=4 or 7.1-50.8 gal. The strength of the earthquake is equivalent to the intensity of II-V MMI.
