Institusional role in analysis of installation of Tsunami Natural Disaster Detection Equipment using Analytical Hierarchy Process (AHP) and Cost Benefit Analysis Methods

Abstract

The problem of natural disasters, such as tsunamis, tends to increase from year to year, mainly due to Indonesia's location in the Pacific Ring of Fire (Ring of Fire) and exacerbated by the lack of tools that can inform early for people if a geological disaster will occur and the lack of early warning for geological disasters installed according to local needs. The tsunami disaster will have a harmful and destructive impact on an area where the community suffers a significant material loss. Therefore, this study aims to determine the priority weight of each region in installing early warning tools to minimize the risk of geological disasters in Indonesia using the AHP (Analytical Hierarchy Process) and Cost-Benefit Analysis methods. This type of research is descriptive exploratory research, using qualitative data analysis methods—classifying regional criteria in Indonesia to determine the installation zone for early detection of natural disasters. The weighting and assessment are carried out on regional factors. Early detection tools for natural disasters are determined using the Analytical Hierarchy Process (AHP) method, which provides subjective calculations based on the hierarchical structure of regional components, namely Dense Settlements, Business Activities, Strategic Buildings Conservation Areas. The subjective calculation is combined with sub-criteria components from the area in coastal settlements, urban settlements, significant business activities, small business activities, important strategic buildings, historical strategic buildings, water conservation areas, and wildlife conservation areas. They support data taken directly through questionnaires and secondary data as comparison data. The data and results of AHP calculations are presented in the form of a parameter table based on the factor component of the regional component. The results of the analysis show that the detectors are divided into four types, namely CBT, Buy, Gauge, and ISDL

Vibration and Displacement Monitoring of Surface and Rock Strata in Geological Hazards Based on Mixed Technologies

“…System Architecture. At present, in the process of geological disaster prevention and control, the combination of Internet of Things technology, sensor technology, automa-tion technology [13][14][15][16], and other means to respond has become an important part of geological disaster monitoring and prevention work. In order to realize the remote automatic monitoring of geological disasters on the surface and rock strata, a set of automatic monitoring system was built, which mainly consists of sensors, wireless transmission, data processing, monitoring, and alarm.…”

Technology content assessment for Indonesia-cable based tsunameter development strategy using technometrics model

“…There have been 69 tsunamis with a validity status of "definite tsunami" and 55 tsunamis with a validity status of "probable tsunami" in Indonesia from 416 to 2018 for the Assessment and Application of Technology or BPPT received a mandate to support the operation of INA-TEWS to assist the community and other government institutions [5]. Therefore, in 2019, the BPPT Center of Technology for Electronics (CTE) built and developed INA-CBT, part of INA-TEWS [6].…”

“…Strategi Pemulihan Sektor Pertanian Pasca Gempa Bumi di Kabupaten Cianjur Pendahuluan Indonesia terletak di kawasan the ring of fire sehingga menjadi salah satu negara yang sering mengalami beragam bencana alam (Manurung et al 2022;Nurjanah dan Apriliani 2021). BNPB (2022) melaporkan per 26 November 2022 telah terjadi 3.116 bencana alam di Indonesia.…”
