In turn, this evidence-based information could be one of the essential feeders to policymakers and disaster managers on what disaster risk reduction programmes have a better chance of being accepted by the local players. One aspect is the perception of disaster risk occurrence either the disaster affects the development or otherwise.
Series of focus group discussions were conducted for data collection purposes, and the data was analyzed narratively. These local players were the authorities at the federal and state level, industry players, and academicians. Therefore, this paper presents how the local players perceive disaster risk in underground utility development. Even it is subjective it is vital to understand what risks people consider to be acceptable, especially the local players involved in the development works. It depends on how an individual or group of individuals see or assess the characteristics of a phenomenon. However, the risk of disasters is a matter of perception. The risk of development (or disaster) depends on the nature of the development itself and the potential disaster in the development area. The data obtained is expected to be used as supporting data for disaster potential-based regional planning. Furthermore, based on the results of the analysis of soil engineering assessments, tuff sediment as a surface layer that has experienced landslides has been identified as having susceptible lithological engineering properties because it has undergone quite intensive oxidation and weathering. The results of the geoelectric analysis indicate that there are three lithological layers in the study area namely tuff sediments with resistivity values and depths between (1-40 Ωm 0.4-4 m), clay sand (40-120 Ωm 2-4 m), and solid breccias with igneous rock components (>120 Ωm 2–22 m). The purpose of this study was to determine the arrangement of rocks that are in the landslide-prone zone in Panjang District using the geoelectric resistivity method and to analyze the soil engineering assessment obtained from the results of lithological analysis using X-Ray Diffraction (XRD). Based on previous research, this area has been recorded as having several historical points of landslides, but there is no mitigation/response specifically for this type of disaster.
One of the potential disasters in Bandar Lampung, especially in Panjang District is a mass movement/landslide. To support sustainable development in a city area, it is necessary to have a regional arrangement concept that considers all aspects, one of which is the potential disaster aspect. Bandar Lampung is a densely populated urban area consisting of land and water with several plateaus and mountains that stretch across this region. Data yang diperoleh ini diharapkan dapat dimanfaatkan sebagai data dukung penataan wilayah berbasis potensi bencana.ABSTRACT. Selanjutnya berdasarkan hasil analisis penilaian keteknikan tanah, sedimen tuf sebagai lapisan permukaan yang mengalami longsoran diidentifikasi memiliki sifat keteknikan litologi yang rentan karena telah mengalami oksidasi dan pelapukan yang cukup intensif. Hasil analisis dua lintasan geolistrik mengindikasikan adanya tiga lapisan litologi pada daerah penelitian, yaitu sedimen tuf dengan nilai resistivitas dan kedalaman antara (1-40 Ωm 0,4-4 m), zona kontak atau bidang gelincir (40-120 Ωm 2-4 m), dan breksi padu dengan komponen batuan beku (> 120 Ωm 2–22 m). Tujuan dari penelitian ini adalah untuk mengetahui susunan batuan yang berada pada zona rawan longsor Kecamatan Panjang menggunakan metode geolistrik resistivitas serta untuk mengetahui hasil penilaian keteknikan tanah yang diperoleh dari hasil analisis litologi menggunakan X-Ray Diffraction (XRD).
Berdasarkan penelitian sebelumnya, daerah ini terekam memiliki beberapa titik sejarah longsor tetapi belum ada mitigasi/penanggulangan yang diaplikasikan khusus untuk jenis bencana tersebut. Salah satu bencana yang berpotensi terjadi di Bandar Lampung, khususnya di Kecamatan Panjang, adalah gerakan massa/longsoran. Untuk mendukung pembangunan yang berkelanjutan di sebuah kawasan kota diperlukan konsep penataan wilayah yang mempertimbangkan segala aspek, salah satunya adalah aspek potensi bencana. Bandar Lampung merupakan wilayah perkotaan padat penduduk yang terdiri atas daratan dan perairan dengan beberapa dataran tinggi dan pegunungan yang terbentang di wilayah ini.
