Abstract

Wosi is a sub-district located in Manokwari Regency and is a part of the Wosi River Alisan Area (DAS) which has vulnerability to forest cover due to the conversion of settlements and trade centers. Based on this, it is necessary to mitigate the flood disaster structure or carry out flood risk management. One of the government's efforts or policies in flood risk management in Wosi Village is to restore the function of the Wosi watershed through relocation. The Willingness to Pay (WTP) and Willingness to Accept (WTA) approaches related to relocation problems can estimate the WTP and WTA values so that they can optimize the form of policies in reducing flood risk. The results of the analysis show that first, Willingness to Pay flood disaster management through relocation is significantly influenced by education level, income, number of dependents, length of stay and area of residence. Willing to accept a compensation fund of approximately Rp. 32,000,000 to Rp. 506.666,666 and Total WTA is around 1,096,000,000. WTP funds that are willing to be paid are Rp. 82,655,533 (Average WTP) and Rp. 2,479,666,000 (Total value of WTP). The amount of Willingness to Accept is smaller than Willingness to Pay, proving that the paired comparison method can reduce the WTA-WTP gap. In addition, the community's understanding of flood risk reduction in the Wosi watershed is still not optimal, so that the efforts of all parties, especially the local government, in carrying out various policies, plans, and programs that can contribute to risk reduction.

Abstract

This study determined the management of disaster risk reduction in Wamesa Village, South Manokwari District, West Papua Province, and evaluated the level of vulnerability, capacity, and risk of the tsunami catastrophe threat. This research is a quantitative and qualitative research that uses analytical descriptive methods that describe the context of vulnerability and capacity in the research location. The primary data were collected through interviews with community development cadres of Wamesa village as well as documentation (mapping) of social, economic, physical and environmental data at the research location referring to the technical research guidelines for tsunami disaster risk study. Secondary data to see potential threats as well as vulnerability and capacity level assessments were obtained from the relevant agencies. The results found that the level of vulnerability and capacity of the Wamesa village community to the tsunami disaster was categorized as high with a vulnerability and capacity index values were 2.21 and 2.54, respectively. Wamesa village, in general, is at intermediate risk of a tsunami disaster, with a total of 0.92 ha of the hamlet's land area being at low risk, 46.13 ha being at moderate risk, and 2.91 ha being at high risk. The management of disaster risk reduction in Wamesa village needs to be strengthened by integrating risk assessment and disaster mitigation activities into village planning and budgeting so it can be sustainable and contributes to reducing vulnerability and increasing the capacity of the Wamesa village against the threat of a tsunami disaster.
