This article was written to explain the ability of Geography Education students to do horizontal evacuation to a tsunami safe zone in Padang City and a silent simulation as an alternative of horizontal evacuation. In this research, respondents were asked to do horizontal evacuation in 3 ways, that is walking, power walking and running. The measurement result data were analyzed and compared with the estimated arrival time of tsunami wave in three scenarios based on gender. The results of the research are 1) 47.76 % of respondents did not know the nearest tsunami safe zone from their places; 2) if the earthquake and tsunami scenarios 1 and 2 occurred, the recommended horizontal evacuation technique was running. Silent simulation is a horizontal evacuation simulation carried out independently by residents without waiting for the simulation schedule by the government or related institutions. Silent simulation can be done alone, with family, or with the closest neighbours and combined with daily activities such as marathons or jogging. Through this silent simulation practice, residents can find out the most appropriate evacuation method and the fastest evacuation route to the nearest tsunami safe zone from their respective homes.Keywords: silent simulation, geography education, tsunami safe zone, PadangArtikel ini ditulis untuk menjelaskan kemampuan mahasiswa Pendidikan Geografi dalam melakukan evakuasi horizontal ke zona aman tsunami di Kota Padang dan silent simulation sebagai alternatif evakuasi horizontal.

Tsunami Run Up

Historical record showed in 1977, tsunami attacked Lombok and caused extensive damages due to tectonic activity. Kuta Bay located in the southern area of Lombok has a high risk of earthquake and tsunami, thus mitigation plan on tsunami attack is very important. This study aimed to determine the arrival time, run-up height of tsunami and the coverage areas, so it could be used to determine the temporary shelter location (Tempat Evakuasi Sementara-TES). Simulation of the tsunami wave propagation used the TUNAMI modified (beta version) program with three scenarios of earthquake magnitude variation (Mw), namely 7.7, 8.1, 8.3, and 7.9 (based on the Sumba earthquake event in 1977). Field surveys, questionnaire distributions, and interviews were used in determining input parameters of Tsunami Evacuation Simulation (Simulasi Evakuasi Tsunami-SET) by using 2011 EVACUWARE 1.0 version. Tsunami wave propagation simulation showed the tsunami arrival time on Kuta Bay ranged between 21 - 38 minutes. Tsunami run-up height was about 1.01 - 8.71 meters along Kuta Bay, with the farthest distance of inundation was 860 meters from the seashore. The percentage of survivors based on SET results in scenario 1 and 2 for 20 minutes of evacuation time were respectively, 63.62% and 93.27%.

Purpose PT Garuda Indonesia (GIAA) Persero Tbk is the one only pride airline of Indonesian sovereignty. Although the bird achieved abundant international awards and certifications, the bird is dying and needs a remedy immediately. The frequent annual turnover of board executives did not make impact to the financial performance; this seems to be tip of the iceberg, peculiar with the number of restatement over the past decade. Therefore, this paper aims to address the issue through the function of five red flags model which known as Altman Z-score, Sprigate S-score, Grover G-score, Beneish M-score and Dechow F-score. Design/methodology/approach This is exploratory study of univariate analysis using financial distress and fraudulent financial statement approach, while the type of data is secondary taken from Indonesia Stock Exchange during 12 years observation from 2007 to 2018. Findings Altman, Springate and Grover produce strong indication of GIAA’s financial distress; all models score the same distress indication by 14 times. All distress models agreed that only 2011 and 2012 classify to the safe zone when GIAA performed the corporate actions. Beneish scores fraud indication by eight times. Dechow scores slightly higher by nine times. The number of fraud predictions in this research are in line with the number of restatement, which proves the assumption that restatement can be used as a signal of the financial statement fraud. When GIAA categorized in safe zone, both Beneish and Dechow score no to fraud, this indicates the fraud occurence during health period is lower. Research limitations/implications The motivation behind the financial statement fraud is not discuss through this research but from the primary theory of the fraud triangle. Financial distress possesses strong relationship with pressure factor; therefore, exit from financial crisis is one of the best solution to mitigate the financial statement fraud. Practical implications The average of Beneish score is −2,26, slightly above the manipulator threshold which is −2,22. This must be marked as an ample conjecture of GIAA’s fraud inclination and been a highlight for the auditor both internal and external when performing control testing, attestation and other assurance services. Social implications All models in this study can apply to any other corporate issues, especially for evaluating the government company who has loosen the public trust recently in Indonesia such as PT Asuransi Jiwasraya and PT Asabri. Moreover, the pandemic COVID-19 has brought the world to the new unprecedented risk, especially the economic turmoil which lead the possibilities of corporate distress and fraud. By applying these scores, public might have tools as pre-elemenary assessment to serve a decision where to put trust in a company. Originality/value This paper reveals a combination from various models of financial distress and financial statement fraud in order to generate the financial solutions named « DDCC » Debt Restructuring, Debt Conversion, Capex Management and Cost Cutting.

This study presents methods of transit signal priority without transit-only lanes for a transit-based emergency evacuation in a sudden-onset disaster. Arterial priority signal coordination is optimized when a traffic signal control system provides priority signals for transit vehicles along an evacuation route. Transit signal priority is determined by “transit vehicle arrival time estimation,” “queuing vehicle dissipation time estimation,” “traffic signal status estimation,” “transit signal optimization,” and “arterial traffic signal coordination for transit vehicle in evacuation route.” It takes advantage of the large capacities of transit vehicles, reduces the evacuation time, and evacuates as many evacuees as possible. The proposed methods were tested on a simulation platform with Paramics V6.0. To evaluate and compare the performance of transit signal priority, three scenarios were simulated in the simulator. The results indicate that the methods of this study can reduce the travel times of transit vehicles along an evacuation route by 13% and 10%, improve the standard deviation of travel time by 16% and 46%, and decrease the average person delay at a signalized intersection by 22% and 17% when the traffic flow saturation along an evacuation route is0.8<V/C≤1.0andV/C>1.0, respectively.

Geographical location of North Buton Regency which directly opposite the Banda Sea and placed in the reverse fault of Makassar Strait, Matano fault, Lawanoppo, and Kolaka, which are tsunami-prone areas due to earthquake and submarine landslide. These then caused the area has high disaster risk, because of the settlement that is located on the seashore. Therefore, a study to understand the preparedness level of community in North Buton Regency in confronting the tsunami disaster is needed; in order to be able to determine the mitigation steps, also the effective evacuation route and location to minimize the casualties caused by tsunami. Kulisusu Sub-district is a territory with a fairly long coastal area, wherein the population density is the highest in North Buton Regency, this then made the area has high disaster risk. This research used questionnaire instrument to discover the preparedness level of the community, and the numerical simulation method with multi-agent system in the tsunami evacuation simulation. The conducted simulation did not specify the evacuation route or path, yet the agents were allowed to move freely to the shelter. The simulation was conducted at day and night time. The result of the research pointed on matter of preparedness level of community, in which factor of preparedness of the community in facing the disaster is very important, by the means of establishing simulation drill, preparing the controller officers, and managing the comfort on the shelter, such as strategic location and good position, also creating a good early warning system so that more residents could be saved.
