## 2 Materials and Methods  
The research employed a case study approach. The focus of the highlighted study was the central part of the Lembang Fault, which is located in the municipality of Western Bandung and the municipality of the city of Bandung. The analysis of CDR unit was the central part of the Lembang Fault area, which comprises of four districts in the districts of Parongpong, Cisarua, and Lembang of the municipality of Western Bandung, as well as the district of Sukasari of the municipality of the city of Bandung. To provide an overview of demographic and local economic characteristics of the case study area, the publications of the Statistics of Indonesia, or Badan Pusat Statistik (BPS) in Bahasa Indonesia, on the social and economic statistics of the four districts were utilized. For acquiring information concerning natural and built environment and land use/land cover, as well as their changes between 2019 and 2021, Level 2A Sentinel-2 satellite images, geometrically corrected by means of bottom-of-atmosphere (BOA) radiometric correction of reflectance, were employed. The satellite images were processed by means of a supervised classification method. See Figures 2-4 for details. Information concerning policy, regulations, and procedures on DRM were acquired from regulations at national, provincial, and local levels. Furthermore, two types of interviews were performed. First, to acquire information on risk knowledge particularly indigenous knowledge on risks, as well as CDR and DRM in general in the Lembang Fault area, a semi-structured interview was performed. Second, to obtain a deeper understanding concerning people's perception in the scope of other subcategories of CDR, face-to-face structured interviews were conducted with 108 heads of families living in 16 villages within four districts of the Lembang Fault area. The respondents directly provided their answers during the interviews. Additionally, the respondents were allowed to provide more than one answer for each question, while several respondents did not provide answers for few sensitive questions. All interviews were conducted between 31 May and 11 June 2021. See Figure 5 for the location of survey of this research. See also Table 1 for the characteristics of the respondents. The highlighted research also collected information on the Japanese experience on the development of CDR, whose information is a result of a long-term research on CDR. Figure 2: Land use/land cover of Lembang Fault in 2019. In 2019, the land use/land cover of the Lembang Fault area was dominated by forest (44.55%) and agricultural land (30.60%). Settlement areas coverage was 22.80%. Figure 4: Land use/land cover of the Lembang Fault area in 2021. The coverage of forest between 2020 and 2021 had drastically decreased 116,605 ha, while agricultural land coverage at the same period had increased 35,858 ha. In 2021, the coverage of agricultural land (421,646 ha) was already higher than it of forest (411,644 ha). Figure 3: Land use/land cover of Lembang Fault in 2020. Between 2019 and 2020, the coverage of forest had decreased 17,758 ha, while the coverage of settlement areas and agricultural land had increased as much as 18,647 ha and 10,670 ha, respectively. \begin{table}
