Those Indian Ocean beaches that are in the southern sides of the Island of Java are prone to tsunami disaster. However, there were no systematic and scientific study to make analysis of the tsunami disaster mitigation to those tourism beaches. Therefore, a series of policies with comprehensive rescue strategies and efforts to minimize the risk of the tsunami disaster is required. The purpose of this study was to determine places of tsunami evacuation for the tourism beaches in Gunungkidul Regency based on P646 of FEMA (Federal Emergency Management Agency) and compare them with the result of the determine places of tsunami evacuation conducted by BPBD (Local Disaster Management Authority) of Gunungkidul Regency, Yogyakarta. This purpose also includes the want of the authors to implement the method of this study to be the policy of tsunami mitigation for similar tourism beaches in the Special Territory of Yogyakarta as well as similar beaches in Indonesia. This study uses quantitative method with descriptive analysis technique that is analyzing the paths and places of tsunami evacuation based on P646 of FEMA. Given location elevation is the basic ingredient of the analysis, and therefore, elevation data, tsunami arrival time, projected number of visitors to support the analysis need to be gathered. The analysis of the evacuation areas is required to determine the evacuation places that are safe points in the evacuation process. An elevation of a safe point elevation can be a point that is beyond the reach of tsunami waves or safe areas within the tsunami pool areas. The results of this study are the height of the gathering point / safe point 25 meters above sea level to be the basis for saving themselves, if connected with the speed of walking (weak condition), then the arrival time / arrival time of the tsunami is not more than 0.5 hours. This is still within limits in accordance with the Federal Emergency Management Agency (FEMA P-646, 2008), the location of the gathering point / tsunami evacuation safe point can be used as the first rescue of tsunami victims by considering the arrival time of the tsunami. On the other hand, BPBD accommodate tsunami victims using public facilities even though they are far away and heed the arrival time of the tsunami.Keywords: beach, elevation, evacuation, gunungkidul, tsunami ABSTRAKJumlah pengunjung maksimal objek wisata pantai di Kabupaten Gunungkidul antara Tahun 2014-2017 sejumlah 23.728 jiwa per bulan, sehingga jika terjadi tsunami potensi korban sangat besar, maka untuk meminimalkan korban jiwa saat terjadi tsunami diperlukan suatu kebijakan untuk pengurangan risiko terhadap bencana tersebut dengan strategi penyelamatan yang komprehensif dan upayanya menyediakan Sistem Peringatan Dini Tsunami.

Rejowinangun Tourism Village is a village with a lot of potential and began to be developed as an ecotourism area, but still has many problems, both from the environmental aspects, management aspects, to aspects of human resources, so that tourism activities in the region have not developed. Therefore, a study is needed to analyze the potentials of community-based ecotourism development in Rejowinangun Tourism Village, and to achieve these objectives, an analysis is conducted on all aspects, namely analysis on aspects of tourist objects and attractions,social aspects, management aspects, up to aspects of organizing community empowerment. In collecting data, the method used is community participatory. In this method the community is the central focus and the ultimate goal of the activity, citizen participation will increase citizens' self-esteem and the ability to be able to participate in the mission concerning the community and village.

Various attempts have been made to reduce the height of the puddle, when mixing the fresh concrete in a frame work of sub-structure elements, e.g. the foot-plate foundation. The puddles in the foundry area potentially affect the composition of the mortar especially in water-cement ratio (wcr). This caused a decrease of compressive strength (f’c) of the concrete then causing the quality decreaseof the concrete. This research used two types of mixed concreteconditions: dry and waterlogged condition. The water cement ratioshould be changed when mixing concrete had been performed in waterlogged condition. One determinedcontrol sample was based on a normal concrete mixture with characteristic strength (f'c) = 25 MPa.

The concrete sampleswere tested using a concrete compressor universal test machine (UTM) than comparedto hammer and Ultra Pulse Velocity (UPV) test.Based on the results of the study, the quality of mixed concrete in waterlogged conditions was much lower than the compressive strength design. The percentage reduction in compressed strength of mixed concrete under water submerged conditions ranged from 30.82% to 32.63% to normal concrete compressive strength.
