Abstract
The city of Cilegon in Banten Province, Indonesia is selected as a site of this study. The city locates in the western edge of Java Islands and is known as one of the most famous and significant heavy industrial zones in Indonesia. Cilegon is potentially exposed both to natural and industrial hazards so that we can consider it as a suitable place for studying NATECH (NAtural-Hazard triggered TECHnological disasters) disaster situations. The Indonesian government indicates the presence of seismic gap in the Sunda Strait and the associated tsunami risk. Large-scale facilities of chemical, petrochemical, oil and gas industries stand in coastal areas in Cilegon. The industry and its surrounding communities can be affected by combination of the natural and industrial disasters. In Cilegon, we aim at strengthening capacity of the education section in the Cilegon city government and the school principals and teachers. Our preliminary implementation and survey reveal that knowledge and understanding of teachers are very limited. We will combine existing research findings from both of industrial accidents and tsunami, and develop educational materials.

AbstractPrevious literature on natech (Natural hazard-triggered TECHnological) disasters argue prevailing difficulties in establishing collective response and sharing common knowledge amongst different and a variety of stakeholders. We aim to describe such challenges using a case study and examine the relationship amongst the actors. Our case study focused on the 2018 Mt. Anak Krakatau eruption and the tsunami triggered by it. In this disaster, one of the largest industrial zones in Indonesia was partially affected. Our study largely explains the results based on some series of discussions with private companies and representatives of the residents collected in 2019 (from February to July). We also referred to the publicly available information, which relevant agencies in the Government of Indonesia issued. Although there were no physical damages in the factories and no causalities, staff in many facilities were worried about the situation and the surrounding residents were also scared how things would be going. The residents were not able to behave in collectively organized manner, because they faced with a lack of the synthesized and coordinated information and instructions. The residents were fully aware of the risk of natech disaster, but such awareness was not necessarily connected with reasonable risk perception and organized behaviours. Relevant organizations complied with their own protocols, but it did not necessarily bring better consequences. The meteorological agency disseminated information in their limited capacity. The volcano monitoring agency paid the limited focus on the volcano and its adjacent sea area. The national and local disaster management agencies tried to integrate technical information, but it took time. The companies carefully gathered information, but their priorities initially went to their internal response, including taking care of the families of their employees. These findings indicate that efforts were done in the right course separately and it is hard to achieve harmonized response under great uncertainty during a crisis.

Published: January 2021

Abstract
This research aims to know-how education, media information, event frequency and type of event affect the community’s understanding of disaster mitigation. Primary data has collected from the survey which was conducted in 2011 in Banda Aceh, around six years after the tsunami disaster December 26 2004. This survey did when the sustainability reconstruction program for tsunami post-disaster had been implementing in Aceh in the range of April 16, 2009, to December 31 2012, after its emergency response and reconstruction programs ended on April 16 2009. The research method used is a verification survey with 223 respondents as a sample. The Questionnaire is analyzed using multiple linear regression to test the hypothesis. Qualitative analysis enriches this survey by collecting and evaluating the related documents. Overall, all variables have an influence of 68% on the community’s understanding of disaster mitigation. The media information affects the community’s understanding of disaster mitigation significantly, while the education, event frequency, and type of event do not affect the community’s understanding of disaster mitigation significantly. The originality lies in the integration model of causality theories from the previous ones and uses multiple linear regression to test the model. The limitation is in the number of variables and the object. This fact implies enriching knowledge in the social sciences and as a basis for further new research models of disaster management. It also implies practical people who implement related variables.

Authors: Aidar N. , Farlian T. 
Published: January 2021

Abstract
This study discusses the migration patterns of low-income women in the city of Banda Aceh after the December 26, 2004 tsunami and the factors that affected them. Primary and secondary data were used to determine the factors behind migration. Secondary data were obtained from the Central Statistics Agency, the Population and Civil Registry Office of Banda Aceh City, Baitul Mal Banda Aceh. Primary data were obtained from respondents representing three sample districts, namely Syiah Kuala sub-district, Baiturrahman sub-district and KutaAlam sub-district. All of the respondents were women who made the transition to Banda Aceh after the tsunami and are now permanent residents of the city of Banda Aceh. About 60 women were interviewed using a pre-prepared questionnaire. The data obtained were then analyzed using descriptive analysis based on the Snowball sampling method and simple statistics. The results of the study describe the main reasons that women migrated to the city of Banda Aceh after the tsunami, with 64 percent considering employment and job opportunities, 49.1 migrated because of their husband demands, 72 sought better housing prospects, and 3.3 percent sought to avoid locations impacted by the tsunami. This research demonstrates the need for governmental policies regarding increasing employment opportunities for women so they do not become an economic burden to the city of Banda Aceh.

Abstract
This paper discusses how survivors’ views in preserving dark heritage post-tsunami in Banda Aceh are. Little is known about survivors’ views in preserving the dark heritage and it is not clear what significance values are owned by the survivor in looking at sites that are suspected of being dark heritage in context post-tsunami. The research to date has tended to focus on perspective and preservation decisions from government, experts, and visitors rather than survivor views in the context of post-disaster heritage. This paper promotes survivors’ views in preserving dark heritage as a performance that transcends an emphasis on victim, toward framing a dark heritage construct that is productive and dynamic, a steward for post-tsunami disaster identities who have the significance values. The main question put in this research is: How “survivors’ views” in Banda Aceh together with its stigmatized image and identity can be interpreted in dark heritage post-tsunami disaster? This research is done from an interdisciplinary interpretative approach, using a combination of methods such as narrative and discourse analysis. The research shows survivors have an important role in preserving the dark heritage that productive and dynamic, together with culture and social practices where the mosque is considered as a component of heritage the most important to preserve. The current study is based on 50 peoples as key informant carried out on the July and August 2019, the findings suggest components such as the mosque, Ship PLTD Apung, ship above houses, mass grave, and social practices religious rituals be an important heritage for the community survivor as remembering. Survivor also said that dark heritage has a role practical in the region related to the rebuilding of sustainable urban heritage planning.

Authors: Li Mingzhong , Xue Jiaqi , Qi Minhui 
Published: January 2021

Abstract
Frac-packing has been widely used in the development of unconsolidated sandstone reservoirs because it can meet the needs of stimulation and sand control. In this work, the induced stress generated by the artificial fracture was taken into consideration to simulate the geo-structure of a frac-packing well. The fluid-structure coupling model was utilized to solve the reservoir stress distribution, and the critical equivalent plastic strain was introduced to determine whether the element was damaged. Using the proposed model, the comparison between gravel packing and frac-packing on the critical sanding velocity and sanding region distribution were carried out. Sensitivity analysis of parameters that may affect the sanding of frac-packing well, such as Young's modulus, fracture width and length were conducted as well. The simulation results showed that frac-packing is an effective sand control technique which can reduce the reservoir sanding significantly.

Published: January 2021

Abstract
In this paper, based on the deep foundation pit support of the reconstruction and expansion project of Jiqing expressway, the FLAC3D software is used to establish the numerical calculation model of the deformation support of deep foundation pit under the influence of traffic dynamic load. The numerical calculation results are consistent with the actual project monitoring results. By changing the key support parameters such as pile diameter and pile distance, pile length, the level of piles under different support schemes is analyzed. The results show that the ideal diameter of bored pile is 0.8-1.2m, the spacing is 1.1-1.3m, the length of pile is 23m-28m. The horizontal displacement of pile body and ground settlement decrease with the increase of length and diameter of support pile. Considering the safety of foundation pit and the reduction of project cost, the pile with length 23m and diameter 0.8m is chosen in the practical engineering.

Abstract
The bearing property of Drilling with pre-stressed concrete pile cased pile is closely related to the grouting effect on the pile side. Based on the 3D scanner, the characteristics of the grouting stone body was quickly obtained with large area and high resolution through high-speed laser scanning measurement technology and extrapolation multi-frequency phase-shift laser grating technology, and the following conclusion was drawn: the quantitative characterization method of grouting rock mass based on the 3D scanner is stable and reliable, its workload is small, data density is large, test process is accurate and fast, and it overcomes the shortcomings of traditional manual measurement; under the condition of same elevation, the thickness of grout decreases as the distance away from the coordinate origin increases, namely in the same horizontal plane, the farther the horizontal distance away from the grout outlet position, the smaller the grout thickness; the greater the elevation, as the horizontal distance away from the grout outlet increases, the larger the decrease rate of grout thickness, the faster the grout thickness decreases; when the horizontal distance away from the grout outlet position is constant, as the elevation increases, the grout thickness gradually decreases.

Abstract
The acoustic emission (AE) monitoring technique, scanning electron microscope (SEM) system and uniaxial compression test were carried out to study the effect of pyrite-bearing filling joints on the mechanical properties of coal samples. The results show that the pyrite-bearing filling joints have adverse effect on strength, elastic modulus and peak strain of coal samples. Compared with the relatively complete samples, the post peak failure was ductile of samples with pyrite-bearing filling joints, the stress-strain curve was ladder-shaped after the peak and the AE energy of each drop appeared a peak. Many inclined and slender filling joints on the coal surface had a significant effect on the mechanical properties of the samples. Under the action of axial compression stress, the internal cracks of coal-rock with pyrite-bearing filling joints had enough time to expand and connect, and induced failure of surrounding structures, thus reducing the strengths of the samples. When fine pyrite-bearing filling joints on the coal surface, the distribution of macro-cracks were less, and SEM image showed that the fracture surface was relatively flat. While many inclined and slender filling joints on the coal surface, the sample failure accompanied by more macro-cracks, and SEM image showed that there were more holes and cracks on the fracture surface.
Gradient-Based Production Optimization in Reservoir Development

Published: January 2021

Abstract
One of the core contents of intelligent oilfield is to develop proved oil resources economically and effectively. The way to realize it is to make reservoir development in the optimal state in real time based on the existing production conditions. Water flooding is a commonly used technique after primary oil recovery. However, due to the influence of formation heterogeneity, the injected water breaks through the high permeability layer and traps the crude oil untouched. In order to solve such problems, a new optimal control model is proposed here, which aims to maximize the net present value of reservoir development and production. By solving the mathematical model of development and production, the input and output control parameters of reservoir are optimized in real time to obtain the optimal production scheme. This model is based on the reservoir numerical simulation and optimization theory. By solving the gradient of the control variables, multiple objective strategy schemes (such as the optimal one aiming at oil production, water production and economic benefits) can be optimized according to different needs to assist the oilfield production decision. On the basis of theoretical research, this model is used to optimize the calculation and analysis of reservoir examples, and the results show that the optimal production scheme is in line with the actual oilfield, which provides theoretical and technical support for the intelligent control of oilfield development.

Published: January 2021

Abstract
The Baoxingchang Cu-Mo deposit is an important deposit in the Jinshajiang-Red River alkali-rich porphyry area, Western Yunnan. Fluid inclusion petrography and inclusion microscopic thermometric analysis of quartz phenocrysts in non-mineralized porphyritic granite, lamprophyre quartz veins, molybdenite quartz veins, copper-pyrite-molybdenite quartz veins, and pyrite quartz veins show that the development in primary inclusion of quartz phenocrysts and quartz veins can include vapour-rich inclusions and liquid-rich inclusions. Fluid inclusions are characterised by their medium-high temperature and moderate salinity. However, the temperature and salinity of non-mineralised quartz fluid inclusions are higher than those of quartz fluid inclusions in the mineralisation stage. Captured pressure and mineralisation depth during mineralisation reveal that the copper-molybdenum deposit is formed in hypabyssal environment, which is consistent with porphyry metalloginic systems.

Authors: Yang Huohai , Liu Yuhang , Ren Shirui 
Published: January 2021

Abstract
Natural gas hydrate is an important clean energy in the future because of its high energy density, clean and pollution-free, large amount of resources and wide distribution. Coiled tubing horizontal well drilling can ensure reservoir drilling rate, increase reservoir drainage area, improve development efficiency, and solve the problem of conventional horizontal well drilling trajectory control caused by shallow hydrate reservoir. In the process of drilling horizontal wells with coiled tubing, the gas hydrate is decomposed into gaseous gas due to the change of temperature and pressure environment. The multiphase transient flow of gas in the wellbore will affect the wellbore temperature and pressure environment and cause well control risk. The calculation model of multiphase transient flow in deep water gas hydrate horizontal wells is established. The gas distribution and migration law in the wellbore are analysed. The variation of wellbore pressure and ground flow law are mastered. The theoretical basis and construction reference are provided for deep water gas hydrate continuous horizontal wells drilling.

Abstract
The Earthquake in 2005 has destroyed a large part of the Khyber Pakhtunkhwa Province (Pakistan) and Kashmir which has created questions regarding the adequacy of framed structures in order to resist strong motions, as due to this earthquake many buildings were damaged badly or were devastated. In order to evaluate the framed structure’s performance under future expected earthquakes, a non-linear static analysis i.e. Push over analysis has been carried out. So for achieving our objective of analysing the framed structure’s performance under seismic loading, a 4 storey’s framed structure was selected and analysed. From the results that were obtained from this study shows that the framed structures which are properly designed under gravity will perform in a safe zone under seismic loading. Certain response parameters predicted by each pushover analysis which were obtained from Gravity & Earthquake load patterns were analysed and compared with each other for differences. The observations made from the current study clearly showed that pushover analysis results depend on three factors i.e. 1-the load path, 2-structure properties and 3-features of the ground motion. The response parameters were estimated by applying the displacement of target at the control node. The accuracy of the predictions depends mainly on the approximations involved in the theory of the procedures, structural properties and features of ground motion.
