Kesiapan infrastruktur data spasial sebagai upaya mitigasi banjir lahar di kali putih Kabupaten Magelang Jawa Tengah

Abstract

Availability of Spatial Data Infrastructure (SDI) has an important role in disaster management. The purpose of this research is to analyze the readiness of the Spatial Data Infrastructure (IDS) as an effort to mitigate the lava flood in Kali Putih, Magelang Regency, Central Java. The research method was carried out by interview, survey and secondary data collection and SWOT analysis. The results of the SWOT analysis, on the Strength-Opportunity matrix, conclude that the optimization of Spatial Data Infrastructure (IDS) and the Indonesian National Standard (SNI) in the field of Geospatial Information (IG). The Strenght-Threath analysis concludes the need to use quality spatial data for government agencies. Opportunity - Weakness analysis concludes that there is a need for Web GIS development and the need to improve the quality of GI and the quality of human resources in the field of GI. Threat-Weakness analysis resulted in a conclusion, namely the need to refer to the one map and one data policy as well as the ID and SDI field policies.

Mapping the Lava Flood Hazard Using the Flood Discharge Approach and 2D Hydrodynamic Modeling at the Rejali River, Mount Semeru

“…The impact caused by the cold lava flood (hereafter lava flood) induced building infrastructure damage and casualties (Purba et al, 2022). Therefore, mitigations are needed to anticipate the effect that may occur (Permatasari et al, 2021). One of the mitigation efforts is to develop a lava flood hazard map represented by the distribution of lava floods at specific periods and frequencies using modeling approaches (Kholiq, 2017).…”

Mapping Flood-Prone Areas Using GIS Through as Geo-Artificial Intelligence (Geo-Ai) Approach in Bengkulu City

“…Floods can have negative socio-economic impacts, loss of people and property, health-related problems, and ecosystem functions [10]. Public awareness about the importance of protecting the environment and behavior in disposing of waste properly are also important factors in preventing flooding [11]. Lack of awareness and environmentally unfriendly behaviors can cause drainage channels to clog and exacerbate flooding [12].…”
