Abstract

Klaten Regency is one of the areas affected by the 2006 Yogyakarta earthquake disaster. Several sub-districts experienced the impact of this disaster, including Wedi Sub-District, Gantiwarno Sub-District, and Prambanan Sub-District. The earthquake caused casualties and damage in Klaten Regency. An earthquake disaster is a disaster that can occur at any time, so there is a need for community preparedness in facing disasters by knowing community resilience. This research aims to measure the community resilience index of the three sub-districts in facing earthquake disasters. This research was conducted on 359 respondents, namely 144 respondents in Wedi Sub-District, 103 respondents in Gantiwarno Sub-District, and 112 respondents in Prambanan Sub-District. Respondents filled out the questionnaire by looking at 4 (four) aspects, namely social aspects, economic aspects, institutional or institutional aspects and physical aspects. Data analysis uses the Guttman scale and there are 5 (five) categories of resilience index levels, namely very low, low, moderate, high, very high. The calculation results show that the Wedi Sub-District resilience index value is 1.18; Gantiwarno Sub-District was 1.16; Prambanan Sub-District is 1.11 and the three sub-districts are in the moderate category.

Abstract

Tunnels are important infrastructures, but faults and internal water pressure can reduce their seismic performance. These risks are relevant in seismic regions including Indonesia. Although finite element methods are used to analyze tunnel behavior, models with continuous linings overestimate stresses, while the influence of segmental joints remains underexplored. This study investigates the seismic response of the Bener Dam diversion tunnel, Central Java, Indonesia, which crosses an inactive fault and uses segmental lining, using nonlinear time-history finite element analysis. Three scenarios were analyzed: presence versus absence of a fault, empty versus water-filled conditions, and continuous versus jointed linings. The results indicated that fault-crossing tunnels are most vulnerable to horizontal slip, especially under pulse-like earthquakes, with strains concentrated near faults. Water minimally affects deformation but increases internal stress, while segmental joints elevate peak strain yet localize damage. These findings highlighted the need to consider fault, water, and joint effects in seismic tunnel design.
