Reviewing the willingness of the community to implement absorption wells and biopore in disaster mitigation management of Semarang City

Abstract

Semarang city is growing larger, with a population of more than 1.5 million. As one of Indonesia's important cities, Semarang faces water management and disaster problems. The city faces various problems such as groundwater scarcity, land subsidence, flood, and drought. In order to maintain the ecological function of Semarang, water management by applying rainwater management through rainwater harvesting and by making absorption and biopore wells have become necessary. Community as a subject needs to be involved in this effort, but this effort is often less successful in Indonesia. This study aims to evaluate the willingness and constraints of the community to apply absorption wells and biopores to maintain the ecological urban areas' functions. This study utilizes remote sensing data to identify community groups and questionnaires to assess community willingness. The primary methods are spatial analysis and non-parametric statistical techniques based on questionnaires. Social variables involve aspects of community attitudes, gender, education, and income. Landscape variables involve aspects of altitude and type of settlement. At the same time, this study's results show that the community's willingness is very diverse in every social group and different landscape.
