Application of the clarke-wright algorithm in determining tsunami disaster evacuation route in Purworejo district

Abstract The potentials for tsunami in Indonesia are spread over many areas, one of which is Purworejo. Purworejo has a high tsunami potential because it is located on the Indo-Australian plate. In Central Java, Purworejo occupies the 3rd position in the tsunami-prone area. Therefore, a route is needed to evacuate the population to mitigate the tsunami. This research focuses on two sub-districts, namely Ngombol and Purwodadi. The problems in this paper are: (1) Which points can be used as evacuation sites (2) How to model tsunami evacuation routes with graphs (3) What are the optimal evacuation routes. The method used to find the evacuation route is the VRP with time window. The algorithm used is Clarke Wright algorithm. The optimal evacuation route is obtained if all points are evacuated with minimal time and distance. From nine final evacuation points, only 4 points that fulfill criteria for the shortest distance and can be accessed by vehicles. There are eight final routes with minimum time of 42 minutes. Each of depots B3 and C2 has 3 routes. Whereas each of depots C4 and C5 has 1 route.

Evacuation Route

Southern part of Bali, especially the regency of Badung, in addition to having natural beauty and popular tourist attraction, it has a high potential for disaster. The fact is the coastline of Bali in the south is prone to tsunami because Bali is located close to the colliding zone between the Indo-Australian plate and the Eurasia plate, which presents the main source of local tsunami that could hit the island of Bali. This research undertakes the design and development of a Geographic Information System (GIS) that can provide information and socialization of potential tsunami impact areas and safe gathering places for coastal tourism area in Badung regency. This application is built web-based by using Google Maps API v3. In this Geographic Information System, users can identify potential tsunami impact areas, obtain information on evacuation methods in the event of a tsunami disaster and can find the nearest safe gathering places to do evacuation. By utilizing geolocation and direction services from Google Maps API v3, simulation of the nearest evacuation route has been successfully built. Evacuation is done by considering two possible evacuation sites. The first possibility is to evacuate to the nearest vertical high building, and the second evacuation site is away from the danger zone (red zone) and towards the safe zone (yellow zone or outside the yellow zone).

For flood risk assessment, it is necessary to quantify the uncertainty of spatiotemporal changes in floods by analyzing space and time simultaneously. This study designed and tested a methodology for the designation of evacuation routes that takes into account spatial and temporal inundation and tested the methodology by applying it to a flood-prone area of Seoul, Korea. For flood prediction, the non-linear auto-regressive with exogenous inputs neural network was utilized, and the geographic information system was utilized to classify evacuations by walking hazard level as well as to designate evacuation routes. The results of this study show that the artificial neural network can be used to shorten the flood prediction process. The results demonstrate that adaptability and safety have to be ensured in a flood by planning the evacuation route in a flexible manner based on the occurrence of, and change in, evacuation possibilities according to walking hazard regions.

The City

Facility of directions to the evacuation places in the city of Bengkulu is very minimal, so that people are very difficult to find an efficient route to the evacuation places. The problem is how to determine the evacuation route/gathering point. Indonesia is prone to earthquakes because logically, the Indonesian archipelago is at the confluence of three tectonic plates: the Eurasian plate, the Australian plate and the Pacific plate. In the event of an earthquake and tsunami disaster, if disaster preparedness is not prepared, it will cause damage to buildings, offices and can result in fatalities such as the events in Nangro Aceh Darussalam. Therefore, we need a system that can help overcome this disaster management. The system that can be made is the Information System for Determining Earthquake and Tsunami Evacuation Paths in the city of Bengkulu Using Android. By using Android, it will be easier for people to imitate an evacuation route or place during an earthquake and tsunami.

ABSTRACTThe tsunami often hitthe southern coast of Java several times, where Parangtritis located in that area. This is due to the meeting of Indo-Australian plate with the Eurasian plate in the south of Java that results in a major tectonic tsunami source. Tsunami waves from this region takes 50 to 100 minutes to reach the beach. Considering the short span of time to self-rescue, than its necessary to concieve a map of vulnerability to the tsunami region to plan evacuation routes and tsunami temporary evacuation place (TES) tsunami incoastal village of Parangtritis. The material used as an object to study in this research is the vulnerability of the tsunami, tsunami runoff based on the runup height, the proposed evacuation routes and tsunami temporary evacuation place (TES) as. The result,village in Parangtritis is a tsunami prone areas with vast percentage of the tsunami-prone areas at 66.45%. When the tsunami run up reach 16m the affected area was 788.07 Ha. There are three proposed evacuation route through the Parangtritis roads, Depok roads and Depok-Parangtritis roads. There are 12 proposed temporary evacuation place which spread in the village Parangtritis. Keywords: Inundation, Plate, Runup

The Impact

A natural disaster is a natural event that has a major impact on the human population. One of the natural events that became the focus of this PKM activity was an earthquake. Earthquakes are natural events in the form of vibrations or wavy movements on the earth's crust caused by internal forces. Earthquakes caused by shifting of the ground are called tectonic earthquakes and earthquakes caused by volcanoes are called volcanic earthquakes. Indonesia is an earthquake-prone area because it is located on three plates, namely the Eurasian Plate, the Pacific Plate, and the Indo-Australian Plate. Only in western, central and southern Kalimantan, the source of the earthquake was not found. To reduce the impact of risk during an earthquake, it is necessary to carry out an earthquake mitigation to the community in areas prone to earthquakes. Earthquake mitigation that will be carried out in this PKM activity is in the form of counseling through online webinars to prevent physical contact or crowds, related to the Covid19 pandemic. As a result, from the questions asked by participants, there is still a lack of understanding of the dangers of changing the function of the building or the building's use limit based on the design load and the condition of the building after the earthquake. So for the next PKM, it is recommended to make general information guidelines such as examples of photos or pictures about the condition of buildings that need to be reviewed for repairs or are no longer suitable for use after being hit by an earthquake.Bencana alam adalah suatu peristiwa alam yang mengakibatkan dampak besar bagi populasi manusia. Salah satu peristiwa alam yang menjadi fokus dalam kegiatan PKM ini adalah gempa bumi. Gempa bumi merupakan fenomena alam berupa getaran atau gerakan bergelombang pada lempeng bumi yang disebabkan oleh tenaga yang berasaldari dalam bumi. Gempa yang disebabkan oleh pergeseran tanah dinamakan gempa tektonik dan gempa yang disebabkan oleh gunung berapi dinamakan gempa vulkanik. Indonesia merupakan daerah rawan gempa karena terletak di atas tiga lempeng yakni Lempeng Eurasia, Lempeng Pasifik, dan Lempeng Indo-Australia. Hanya di Kalimantan bagian barat, tengah, dan selatan, sumber gempa bumi tidak ditemukan. Untuk mengurangi dampak resiko pada saat gempa perlu dilakukan suatu mitigasi gempa kepada masyarakat di daerah yang rawan terjadi gempa bumi. Mitigasi gempa yang akan dilakukan dalam kegiatan PKM ini berupa penyuluhan melalui webinar secara online untuk mencegah kontak fisik atau kerumunan, berhubungan dengan pandemi Covid19. Hasilnya, dari pertanyaan yang diajukan peserta, masih kurang pemahaman bahaya dari mengubah fungsi guna bangunan atau batas guna bangunan berdasarkan beban desain dan kondisi bangunan setelah gempa. Maka untuk PKM selanjutnya, disarankan membuat panduan informasi secara umum seperti contoh foto atau gambar tentang kondisi bangunan yang perlu ditinjau untuk perbaikan atau tidak layak guna lagi setelah terkena gempa.
