PENGELOMPOKAN TITIK GEMPA DI PULAU SULAWESI MENGGUNAKAN ALGORITMA ST-DBSCAN (Spatio Temporal-Density Based Spatial Clustering Application with Noise)

Earthquake is a natural disaster which is quite serious in Indonesia, especially on Sulawesi Island. Earthquake is fearful because it can’t be predicted when it will come, where it will come, and how strong the vibration, that often causes fatal damage and casualties. In effort to minimize losses caused by earthquake, it is necessary to divide areas which are easily affected by earthquake. One of the methods that can be used in dividing the area is by using the clustering technique. This research by using a clustering method with the ST-DBSCAN (Spatial Temporal-Density Based Spatial Clustering Application with Noise) algorithm on dataset of earthquake points in Sulawesi Island in 2019. This method by using the spatial distance parameters (Eps1 = 0.45), the temporal distance parameters (Eps2 = 7), and minimum number of cluster members (MinPts = 4), resulting in a total of 60 clusters with 8 large clusters and 216 noises

Natural Disaster at the Closing of the Dutch Golden Age

By the early eighteenth century, the economic primacy, cultural efflorescence, and geopolitical power of the Dutch Republic appeared to be waning. The end of this Golden Age was also an era of natural disasters. Between the late seventeenth and the mid-eighteenth century, Dutch communities weathered numerous calamities, including river and coastal floods, cattle plagues, and an outbreak of strange mollusks that threatened the literal foundations of the Republic. Adam Sundberg demonstrates that these disasters emerged out of longstanding changes in environment and society. They were also fundamental to the Dutch experience and understanding of eighteenth-century decline. Disasters provoked widespread suffering, but they also opened opportunities to retool management strategies, expand the scale of response, and to reconsider the ultimate meaning of catastrophe. This book reveals a dynamic and often resilient picture of a society coping with calamity at odds with historical assessments of eighteenth-century stagnation.

Mood as medium: Reconstruction and the material speculations of “new heritage”

If the politics of aspirational construction appeal to the enchantment of infrastructure, reconstruction usually takes as given an environment of post-conflict, natural disaster, or the degradation of systems of preservation or resource management. If construction and conservation are taken as markers of continuity and political stability what does the urge to build again say about those who exert these ideas in advancement of a set of common goals? Shaped through multi-sited ethnography in Pakistan and the United Arab Emirates, this essay explores the mediation of mood and its material speculations. Concepts borrowed from both the preservation of the moving image and digital forms of heritage restoration provide ways of rethinking the place of reconstruction and coming to a new understanding of its sensual and atmospheric terrain.

Prenatal and Early Postnatal Exposure to A Natural Disaster and Attention-Deficit/Hyperactivity Disorder Symptoms in Indian Children

The aim of this study was to assess the relation between early exposure to stressful event and a level of Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms in children, based on outcomes from a natural experiment. It was hypothesized that children pre- and postnatally exposed to cyclone Aila have a higher level of ADHD symptoms compared to the controls, and the effect depends on timing of exposure. Indian children (8-11y) prenatally (N=336) and early postnatally (N=216) exposed to Aila were compared to non-exposed control group of their peers (N=285). ADHD symptoms were assessed using the Conner’s Teacher Rating Scale Revised. The main effect of exposure to the cyclone on total ADHD symptoms’ score, ADHD index, Hyperactivity and Oppositional symptoms was significant and independent of covariates. Both prenatally and postnatally exposed girls, and only postnatally exposed boys, showed significantly higher level of Oppositional symptoms compared to the controls. Cognitive problems/Inattention symptoms were increased in both prenatally and postnatally exposed boys, but not girls, compared to non-exposed children. The timing of programming the later behavior characteristics by stressful experiences due to natural disaster is not limited to fetal life but extends at least into infancy. Sex is a significant modulator of the early stress-ADHD symptoms association.

DAMPAK COVID-19 TERHADAP ABNORMAL RETURN DAN VOLUME PERDAGANGAN SAHAM

The COVID-19 pandemic is a non-natural disaster that has a huge impact around the world. This research is a quantitative research with event study method. The purpose of this research is to test the capital market reaction by looking at abnormal returns and trading volume activity before and after the COVID-19 non-natural disaster. The event day in this study was April 13rd, 2020 when the Presidential Decree was issued regarding the designation of COVID-19 as a national disaster. Using purposive sampling method, the sample of this study were 27 companies engaged in the hotel, restaurant, and tourism sub-sectors listed on the Indonesia Stock Exchange. The event period is 11 days, namely 5 days before the event, 1 day at the time of the event and 5 days after the event. Data analysis using t-test and wilxocon signed ranks test. The results of this study are: 1) there is no abnormal return during the event period, 2) there is no difference in the average abnormal return before and after the COVID-19 non-natural disaster event, 3) there is no difference in the average trading volume activity before and after the COVID-19 non-natural disaster event and after the COVID-19 non-natural disaster event. Keywords: Event Study, Abnormal Return, Trading Volume Activity, COVID-19.

Why Do Communities Recover Differently after Socio-Natural Disasters? Pathways to Comprehensive Success of Recovery Projects Based on Bam’s (Iran) Neighborhoods’ Perspective

Although recent studies have provided explanations for the causes of success and failure in recovery projects following socio-natural disasters, there is a need for a concise understanding of how different combinations of factors may contribute to recovery failure or success. In this study, to examine the community recovery pathways after the 2003 Bam earthquake, we conducted a fuzzy-set qualitative comparative analysis of 11 neighborhoods in Bam city and Baravat (the neighborhoods represent the division of the areas damaged by the earthquake, as presented by local government). The success of socio-natural disaster recovery projects is presented in three pathways in which the absence or presence of public engagement had a significant influence on the results. The results indicate that a recovery project should respond to the needs of the project within the continuous lifecycle of the project. Additionally, on the one hand, public participation and prompt rescue operations have a significant effect on project success. On the other hand, neglecting the needs of people and the area’s climate in housing design have led to project failure. It is expected that the findings from this study can be used to develop strategies for empowering people in recovery projects and to develop housing guidelines that respect residents’ needs while focusing on on-time and sufficient rescue processes. However, care should be taken when applying the present findings in practice, because every socio-natural disaster is unique and requires careful consideration of complex sets of features.

Registered nurses: can our supply meet the demand during a disaster?

Background Death and destructions are often reported during natural disasters; yet little is known about how hospitals operate during disasters and if there are sufficient resources available for hospitals to provide ongoing care during these catastrophic events. The purpose of this study was to determine if the State of New Jersey had a supply of registered nurses (RNs) that was sufficient to meet the needs of hospitalized patients during a natural disaster – Hurricane Sandy. Methods Secondary data were used to forecast the demand and supply of New Jersey RNs during Hurricane Sandy. Data sources from November 2011 and 2012 included the State Inpatient Databases (SID), American Hospital Association (AHA) Annual Survey on hospital characteristics and staffing data from New Jersey Department of Health. Three models were used to estimate the RN shortage for each hospital, which was the difference between the demand and supply of RN full-time equivalents. Results Data were available on 66 New Jersey hospitals, more than half of which experienced a shortage of RNs during Hurricane Sandy. For hospitals with a RN shortage in ICUs, a 20% increase in observed RN supply was needed to meet the demand; and a 10% increase in observed RN supply was necessary to meet the demand for hospitals with a RN shortage in non-ICUs. Conclusion Findings from this study suggest that many hospitals in New Jersey had a shortage of RNs during Hurricane Sandy. Efforts are needed to improve the availability of nurse resources during a natural disaster.

How Indonesian People in the Past Deal with Disaster Mitigation? An archaeological perspective

Bencana alam adalah bagian dari riwayat bangsa kita sejak masa prasejarah. Meskipun bencana alam merupakan hal yang tidak terpisahkan dari kehidupan masyarakat Indonesia, namun disadari masih kurang kesadaran dan kesiapan terhadap kondisi ini. Hal tersebut ditunjukkan dengan tingginya angka kerugian material dan non material dalam setiap kejadian bencana. Keadaan ini disebabkan oleh belum optimalnya pelaksanaan penanggulangan bencana di Indonesia, khususnya dalam mitigasi bencana. Untuk merumuskan konsepsi baru penanggulangan bencana, masyarakat saat ini harus belajar menghadapi bencana alam dari manusia di masa lalu. Nilai dan kearifan lokal masih relevan hingga saat ini karena kita hidup di nusantara yang sama. Sebagai ilmu yang mempelajari budaya manusia yang telah punah, arkeologi dapat membantu menjelaskan sejarah bencana di suatu wilayah dan dampaknya terhadap kehidupan manusia di masa lalu. Dengan menggunakan pendekatan studi kepustakaan, tulisan ini bertujuan untuk mendeskripsikan aksi mitigasi bencana yang dilakukan oleh leluhur bangsa Indonesia sebagai acuan mitigasi bencana di zaman modern ini. Setidaknya ada dua sorotan nilai yang masih relevan. Pertama, pembinaan mental dan karakter masyarakat yang tinggal di daerah rawan bencana, dan kedua pembangunan fisik mengenai sifat bencana di masing-masing daerah. A natural disaster is part of our nation’s journey from the prehistoric era. Even though natural disaster is an inseparable matter with Indonesian people’s lives, but there is still a lack of awareness and readiness due to this issue. The high number sees it as material and non-material losses in every disaster event. This situation is caused by non-optimally disaster management implementation in Indonesia, especially in disaster mitigation. To formulate the new conception of disaster management, modern people should learn how to deal with natural disasters from ancient people. Values and local wisdom are still relevant today since we live in the same archipelago. As a science that studies extinct human culture, archaeology can help explain the history of disasters in a region and its impact on human life in the past. Using the literature study approach, this paper aims to describe disaster mitigation actions implemented by Indonesia’s ancestors as a reference to disaster mitigation in modern times. At least there are two highlights of values that are still relevant. First is the mental and character building of people who live in a disaster-prone area, and second is the physical development regarding the nature of disaster in each region.
