“…Kondisi ini akhirnya mendorong massa batuan untuk bergerak dalam bentuk tanah longsor. Struktur geologi yang ada adalah bentuk respon dari kekuatan bumi sehingga tanah longsor menjadi peristiwa yang sering ditemukan di daerah yang memiliki morfologi berbukit atau pegunungan dengan material berupa tanah atau batu (Manyoe et al, 2020).…”

Administratively, the research area is located in Pohe Village, Hulonthalangi sub-district, Gorontalo City, Gorontalo Province. Astronomically, the research area is at coordinates 00030'16.10"- 00030'41.58" north latitude and 12302'36.10"- 12303'19.55" east longitude. The purpose of this study was to analyze the type of landslide based on the orientation of the geological structure of the Pohe area and the type of landslide based on the orientation of the geological structure of the Pohe area. The method used in this research is retrieval of field data, namely lithological data, geological structure data and slope data of the research area, then structural data processing using dips 6.0 software application and analyzed using stereographic projections. Based on the results of identification and stereographic analysis, it shows that in the research area there are 2 types of landslides, namely plane failure and toppling failure. The type of plane failure is found at stations 1.1, 1.2, 1.3, 1.4, and 1.6. While the type of landslide toppling failure is found at stations 1.5, 1.7, and 1.8.

“…Landslides generally occur triggered by high rainfall intensity (9). Geological structures in the form of joints and faults are also triggering factors that play a role in landslides (10). Landslides caused damage to public facilities, agricultural land, casualties and even paralyzed the economic activities of people affected by the disaster.…”

Landslides are disasters that often hit several areas in Banjarnegara Regency. The worst landslide incident which claimed many victims occurred on December 12, 2014, in Jemblung Hamlet, Sampang Village, Karangkobar District, which resulted in the settlement of one hamlet being buried. The high risk of landslides in the Karangkobar District necessitates adequate preparedness and capacity. The focus of the research was to determine (1) the level of student preparedness for landslides in Karangkobar District, (2) the level of student adaptive capacity for landslides in Karangkobar District, and (3) the relationship between preparedness and student adaptive capacity. The researchers used a quantitative descriptive method and collected data using questionnaires, observations, and secondary data on disaster events from the Central Regional Management Agency (BPBD) of Banjarnegara Regency. Four junior high schools in the Karangkobar District were studied. The findings showed that preparedness was homogeneous across the four schools. The level of preparedness was moderate, with an index of 71% - 75%. MTs Muhammadiyah Karangkobar was in the high category for adaptive capacity with 80.54%, and other schools were classified as medium. Preparedness correlated with adaptive capacity, with a significance value of 0.035 (<0.05). Keywords: disaster, preparedness, adaptive capacity, landslide

“…Administratively, Kabila Bone District, Bone Bolango Regency, Gorontalo Province, also include the Gorontalo fault regime area as shown in Figure 1. Developing geological structure pattern is influenced by three plates, namely the Banggai-Sula micro plate from the south, the Sangihe plate from the east and the Sulawesi sea plate from the north [1][2][3][4].…”

The research aimed to reconstruct the geological structure and tectonics based on fault, shear fracture and veins data of the Botutonuo and surrounding areas. This research was conducted with DEM interpretation method to determine the lineament pattern of rock offsets and the geological structure mapping method. Geological structure analysis was carried out by using kinematic analysis method of fault, fracture and veins data using the Win Tensor program to obtain the direction and type of stress forming it. Based on the results of the analysis, extensive stress and transtensive stress trendingN-S resulted direction of Normal Fault and Slip Fault (NE-SW). Extensional stress trending (NE-SW) is the result of reorientation stress trending (N-S) in the North Sulawesi arm which is accommodated by the Gorontalo Fault regime. Normal fault and slip fault are the 2nd order faults of the 1st order faults of Gorontalo faults.
