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.

As a country located among three major tectonic plate confluences, namely the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate, Indonesia is an earthquake-prone area. Information about the earthquake occurrences is distributed by the BMKG through social media, websites and television. However, it is undeniable that there are still people who do not have televisions or smartphones. Therefore, earthquake warning systems began to be widely developed. Furthermore, sensors for earthquake vibration detection have an important role in earthquake warning systems. So in this article, the author has conducted a literature study and analysis of the sensors commonly used in earthquake detection systems. This study aimed to present sensor recommendations to be used as earthquake sensors. The result of the literature study, that the author had done, is the selection of sensors is customized to the needs and budget of the project. A description of the sensor recommendations for each project has also been included in this article.

The Impact

The complexity of geographical conditions and regional morphology of Padang City have caused it to be at high risk of multi-hazard. Padang City is located near the meeting point of the Indo-Australian Plate and the Eurasian Plate, and also on the Sumatra Fault line (Semangko Fault). Therefore, strong infrastructures are needed in order to minimize the impact of the risk of multi-hazard. This study is conducted to measure the resilience of Padang City’s infrastructures toward multi-hazard and provide recommendations to improve the resilience of Padang City’s infrastructures toward Multi-hazard. This study was conducted with qualitative methods and presented quantitatively in the form of diagrams. The measurement is carried out based on the concept of city toughness measurements made by UNISDR known as the "Scorecard". This study only focuses on essential 8 about "Increase Infrastructure Resilience" and essential 10 about "Expedite Recovery and Build Back Better". From this study, it can be concluded that the resilience of Padang City infrastructures is still relatively low so several recommendations that are expected will increase the resilience of Padang City’s infrastructures are proposed, that are; in-depth assessment, data collection and supervision monitoring of infrastructures, important assets, and protective infrastructure.

High Level

The Indonesian region has a high level of earthquake vulnerability when compared to other countries. This is because Indonesia's position is at the confluence of three large tectonic plates namely the Eurasian plate, the Indo-Australian plate, and the Pacific plate. The high level of earthquake susceptibility is evidenced by significant earthquake data from 2005 to 2009, which recorded 26 significant earthquakes over a period of 4.8 to 8.6 on the Richter scale. The earthquake also caused impacts including casualties, injuries, damage to houses and destruction of houses.The earthquake event grouping system is a system that functions to classify earthquake events based on two main parameters, namely earthquake strength parameters and earthquake impact parameters. The two parameters are grouped separately, so that the grouping process produces two kinds of grouping results. The stages of this system start from preprocessing data to eliminate noise, then take grouping parameters from the user in the form of the number of clusters, minimum error values, and the maximum iteration limit. Grouping is done using fuzzy c-means method. The grouping results are then displayed in table form and in the form of coordinates in Google Maps.The grouping of earthquake events has been tested by comparing the results of grouping systems with the results of manual grouping. Testing is done by inputting a number of different maximum iterations. Based on the test results it was found that the greater the maximum iteration value will affect the accuracy of grouping.

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.

The purpose of implementing community service is to encourage active participation of mosque takmirs in Bangunharjo Village, Sewon District, Bantul Regency to strengthen their role in handling tectonic earthquakes, especially mitigation. For this reason, activities are directed at enriching knowledge and technology about reducing the impact of earthquakes on the community in a sustainable manner by mosque leaders and administrators so that their role can be effective in mitigation activities. The appropriate participatory approach is an option in carrying out debriefing to motivate mosque administrators to be fully involved in mitigation activities as well as readiness to act and coordinate when an earthquake occurs. Important notes from the community that can be followed up are, among others, the need for assistance is very real, especially from information and technology in handling earthquake problems and strengthening socialization in the form of a curriculum that is more permanent and easy to implement in mosques, especially for children studying in TPA and congregation recitation. This segmentation is expected to be the success of disaster mitigation programs, especially those relating to earthquake mitigation issues related to the religious sector.

Abstract Earthquake is one of the most frequent disasters in Indonesia. This is due to the location of Indonesia which is located between 3 active plates, namely the Pacific Plate, the Indo-Australian Plate and the Eurasian Plate. While from 2018 to date the biggest and worst earthquake in the Lombok Earthquake that occurred with magnitude reached 7 on the Richter Scale and hammer earthquakes with magnitude 7.4 on the Richter Scale. One of the frequent failures caused by the earthquake is the soft store. Soft story mainly occurs in office buildings, hotels or apartments which generally have a lobby or area that is intentionally made without walls / dividers, either on the ground floor or the upper floors so that inter-floor fuss will be different. In designing and modeling structures, buildings are generally designed with open frame type port without walls. The height of the column can also cause a difference between different floors. This study will compare between the wallless portal model with a higher level at the bottom of the building, the middle of the building and the top of the building, where a high level with smaller stiffness has the potential to be soft (soft story). In this study using ETABS 9.7.2 program with spectrum response dynamic load based on the 2017 earthquake map. Results The structure period of the results of the analysis with the program in the crack cross section condition was obtained at 2.01 seconds. The shape mode for the three PPKBB, PKBT and PKBA building types has met the requirements where in shape 1 and 2 building models are translating towards the x or y axis while in shape 3 mode they are twisted. The required mass participation ratio value is reached at the 90% percentage reached at the 8th shape mode for the PKBB and PKBT buildings. While for PKBA it is reached in the 5th shape mode. Deviation values ​​for the three types of building PKBB, PKBT and PKBA are still within the permit limit. Keywords: earthquake, soft storey, spectrum response

ABSTRAKTumbukan miring Lempeng Eurasia dengan Lempeng Indo-Australia membentuk zona subduksi di bagian barat Pulau Sumatra dan sejumlah segmen sesar di darat Pulau Sumatra. Zona subduksi dan segmen sesar yang terbentuk aktif bergerak sehingga sering menimbulkan gempa bumi di wilayah tersebut. Semenjak diberlakukannya Sistem Referensi Geospasial Indonesia 2013 (SRGI 2013) sebagai referensi tunggal dalam aktivitas pemetaan di Indonesia, maka perubahan posisi kerangka referensi koordinat sebagai fungsi waktu akibat dinamika bumi perlu diperhitungkan. Dengan terjadinya dua gempabumi yang berurutan pada tanggal 6 Maret 2007 di wilayah Danau Singkarak Sumatra Barat, akan menimbulkan deformasi koseismik yang dapat mempengaruhi SRGI2013. Dalam penelitian ini dilakukan analisis untuk menentukan model koseismik gempabumi Sianok yang paling sesuai dan sejauh mana dampaknya pada SRGI 2013. Berdasarkan hasil analisis terhadap nilai residual hasil validasi dengan koseismik pada 11 titik pengamatan GPS dapat disimpulkan bahwa model koseismik dari gempabumi Sianok adalah model koseismik menggunakan data parameter gempa dari Global CMT dengan residual misfit 47.5 mm. Secara umum, pola kosesimik gempabumi Sianok mendeskripsikan mekanisme gempabumi sesar geser. Nilai kosesimik terbesar terjadi pada titik KACA dan K108, yaitu 135,43 mm dan 84,74 mm. Besarnya koseismik gempabumi Sianok tidak berpengaruh terhadap peta dengan skala 1: 1000, akan tetapi akan mempengaruhi nilai koordinat Jaring Kontrol Geodesi (JKG) yang berada di sekitar daerah gempa, sehingga perlu adanya pemutakhiran koordinat dari JKG.Kata kunci: Gempabumi Sianok, GPS, Deformasi Koseismik, SRGI2013. ABSTRACTThe oblique movement of Eurasian Plate towards Indo-Australian Plate create subduction zone in the western part of Sumatra Island and some faults on the mainland of Sumatra. These subduction zone and faults actively produce some earthquakes. Since we used the Geospatial Reference System of Indonesia 2013 (SRGI 2013) as one reference on mapping activities in Indonesia, coordinate changes as a function of time caused by earthquake cycle need to be calculated. There are two earthquakes that had been occurred on March 6, 2007 in Singkarak Lake area which affected the SRGI 2013. We analyzed the data to estimate the coseismic model of Sianok earthquake and the impact to the SRGI 2013. The residual from the coseismic model by including 11 GPS displacements shows that the coseismic model of Sianok earthquake is a model that used earthquake parameters from Global CMT with the misfit of 47.5 mm. Overall, this coseismic pattern shows the shear mechanism. The largest displacements are on KACA and K108 sites, that are 135.43 mm and 84.74 mm respectively. The coseimic of Sianok earthquake does not affect a map with scale of 1:1000, but affect the Geodetic Control Network in this area. From this analysis, we conclude that we need to update our Geodetic Control Network.Keywords: Sianok Earthquake, GPS, Coseismic Deformation, SRGI2013.

AbstractMost of Indonesia area is an earthquake- prone region. This is caused by the confluence of three major plates world that are subduction. Indo-Australian Plate colliding with the Eurasian plate off the coast of Sumatra, Java and Nusa Tenggara, while the Pacific plate in northern Guinea and North Maluku. In the vicinity of the meeting location this plate collision energy accumulated in the form of earthquake. The quake destroyed much of the multi-storey buildings that do not have adequate strength. Therefore , the higher the building, the greater the effects of the earthquake were received by the building. One way to acquire resistance to earthquake response was to add rigidity to a building. How to obtain the stiffness of a building is to install bracing for high-rise buildings. The purpose of this analysis was conducted to determine usage behavior particularly bracing displacement. The Results of this analysis showed a reduction in horizontal deviation of the building due to the addition of frame bracing. The difference in the percentage of horizontal deviation without bresing building and building using bresing X is 82.519%. While the difference in the percentage of horizontal deviation without order bresing building and building using bresing V is 64.904%.Keywords: pushover analysis , bracing, displacement,earthquake AbstrakSebagian besar wilayah Indonesia merupakan wilayah rawan gempa. Hal ini disebabkan oleh pertemuan tiga lempeng utama dunia yang bersifat subdaksi. Lempeng Indo- Australia bertabrakan dengan lempeng Eurasia di lepas pantai Sumatra, Jawa dan Nusa Tenggara, sedangkan lempeng Pasific di utara Irian dan Maluku Utara. Di sekitar lokasi pertemuan lempeng ini akumulasi energi tabrakan terkumpul sehingga lepas berupa gempa bumi. Gempa banyak menghancurkan bangunan- bangunan bertingkat yang tidak mempunyai kekuatan yang memadai. Oleh karena itu, semakin tinggi bangunan maka semakin besar pula efek gempa yang diterima oleh bangunan tersebut. Salah satu cara untuk memperoleh ketahanan terhadap respon gempa adalah menambah kekakuan pada suatu bangunan. Cara memperoleh kekakuan suatu bangunan adalah dengan memasang pengekang (bracing) untuk bangunan tinggi. Tujuan dari analisa ini dilakukan untuk mengetahui perilaku pemakaian bracing khususnya displacement. Hasil dari analisa ini menunjukkan terjadinya pengurangan simpangan horizontal gedung karena adanya penambahan rangka bracing. Selisih presentase simpangan horizontal gedung tanpa bresing dan gedung dengan menggunakan bresing X adalah 82,519%. Sedangkan selisih presentase simpangan horizontal gedung tanpa rangka bresing dan gedung dengan menggunakan bresing V adalah 64,904%.Kata kunci: analisa pushover , bracing, displacement, gempa

Geologically, Indonesia is located at the confluence of three of the world's main plates, namely the Indo-Australian Plate, the Eurasian Plate, and the Pacific Plate, which often cause disasters, for example drought. Central Lombok Regency is one of the regencies in West Nusa Tenggara, with these two seasons, most often hit by drought disasters, considering that the rainfall in Central Lombok is very small. So that disaster education and preparedness are needed for residents. This article uses qualitative research methods. The results of the study show that climate field schools have an important role in disaster education. Climate field school is a form of education for farmers that is very useful especially in understanding the weather and climate combined with new agricultural techniques that will allow farmers to plant different crops at different times of the year. Meanwhile, for preparedness, it is carried out through several programs in the form of urging and asking farmers to be disciplined in carrying out cropping patterns according to the zoning in which they are located (rice-padi-palawija or padi-palawija-palawija), mapping of land related to cropping patterns, planting rice parity that requires little water, namely the Situpagendit variety, and urges farmers to insure their rice plants, which is Rp. 36.000/ Ha for one planting season at PT. JASINDI.   Keywords: Indonesia's geological location, disaster, disaster education.

  Indonesia is one of the countries in the world that is vulnerable to various natural disasters. Indonesia is located at the confluence of three main plates of the earth, the Eurasian Plate, the Indo-Australian Plate and the Pacific Plate. One of the disasters that occurred in Indonesia was an earthquake, Yogyakarta is an area prone to experiencing earthquakes more precisely in Bantul district. In 2006 the earthquake in Yogyakarta claimed more than 6500 lives and property losses. The main factor in the emergence of many victims due to disasters is due to lack of knowledge about the disaster and lack of preparedness in anticipating the disaster. The purpose of this study was to measure the preparedness of the head of the family for earthquake disasters in the Piyungan and Pleret sub-districts of Bantul Regency. This type of research is in the form of quantitative descriptive by describing data that has been collected without intending to make conclusions that do not apply to the public. The number of samples is 192 head of family. Sampling of research using acidental sampling for the selection of male head of family respondents. The instruments used were LIPI and UNESCO in 2006. The results of research on the level of disaster preparedness in the majority Piyungan sub-district in the ready category (65-79) were 94 respondents (97.9%), while the Pleret sub-district included in the ready category (65-79) 90 respondents (93.8%). Suggestions from this research are to improve disaster preparedness by conducting training and simulations from the government, BPBD or involving health education institutions.
