Abstract
The submarine boundary layer is a dynamically changing strip located near the seabed interface. The dynamic change process involves the resuspension and redeposition of sediments, which has an important impact on the transportation of seafloor sediments and the transport of offshore chemical substances. Based on the self-developed self-potential monitoring device, the stability of the device and the characteristics of the seabed and the bottom layer of the sea floor with different textures were tested through laboratory experiments. The results show that the self-developed self-potential monitoring probe has high corrosion resistance, good electrode stability, and guaranteed measurement accuracy. The self-potential measurement can clearly identify the position of the seabed interface, and can judge seabed sediments by positive and negative anomalies. Nature, the sandy seabed is negative anomaly (about -8 mv), the clayey seabed is positive anomaly (about 10 mv). The concentration of solid suspended particles in the seawater and the self-potential difference between the seawater and the seabed appear relatively good linear relationship, the smaller the difference, the greater the concentration of solid suspended particles. The re-deposited sediment changes its self-potential under the influence of material composition and pore structure, but this effect gradually decreases as the consolidation time increases. Therefore, the spontaneous potential measurement can better reflect the dynamic changes of the seafloor sediments, and effectively monitor the dynamic changes of the seafloor boundary layer. It provides a new method for the in-situ observation of the dynamic changes of the submarine boundary layer.

Published: November 2020

Abstract
This study uses the construction of the Shengli Bridge Station of Qingdao Metro Line 1 as the engineering support for in-depth research of the deformation and mechanical characteristics of the retaining structure of pile-support systems during deep foundation pit excavation under the complex geological conditions of soil–rock combination. This study adopts the finite element software modeling analysis method to simulate the excavation of the foundation pit and the 3D finite element numerical calculation method to calculate the deformation. The modified Mohr–Coulomb model is selected as the constitutive model, and the natural gravity of each layer of soil is considered. The calculated load includes the dead load of structure and soil. The boundary conditions of X, Y, and Z directions at the bottom are fixed constraints, and the top ground is a free boundary. The displacement of soil around the foundation pit and the stress and deformation of retaining piles and crown beams under different working conditions are studied. The deformation law and force mechanism of the supporting structure of the pile-support system are analyzed. The research results reveal the relationship between the synergy of pile-support system and soil deformation, serving as a reference for similar engineering constructions.

Abstract
Landslide geological hazards are widely distributed and frequently occur in China, especially in the western high mountains and valleys where the terrain is steep and the vegetation is dense and also a large number of hidden and large-scale landslide geological hazards. To solve the problems of the early identification of landslide, we took the high mountain valley area of the Shimian–Hanyuan section of Dadu River as the research object. To conduct an early identification study of landslide hazards in the research area, we used interferometry synthetic aperture radar (InSAR) technology and optical remote sensing technology. The results of our study show that by comparing the identification results of D-InSAR, PS-InSAR, and SBAS-InSAR, we can confirm that the identification effect of SBAS-InSAR technology on landslide geological hazards in mountain valley area is the best. The comparison of the interpretation results of optical remote sensing technology and InSAR technology shows that the optical remote sensing technology can identify the landslide with obvious signs of deformation, and the InSAR technology can identify the geological hazard of the deformation landslide. Furthermore, InSAR technology and optical remote sensing technology can be used synthetically to achieve the early identification of landslide geological hazards.

Authors: Wang Youcheng 
Published: November 2020

Abstract
In the context of deteriorating global environmental conditions, sustainable development has been recognized by more and more people. The concept of sustainability has also been incorporated into many business and consumer behaviors. Companies will use sustainable supply chains to balance three goals, economic, social and environment. Consumers will also adopt many green activities to implement the concept of sustainability. Therefore, the impact of sustainable supply chain on consumers and the impact of consumers’ green behaviors on supply chain are worth discussing and exploring. Exploring the impact of enterprise supply chain on consumers is conducive to enterprises’ better response to consumers. Consumers’ feedback to enterprises is also conducive to the development of new green products. It helps to better implement the concept of sustainable development and reduce environmental damage and resource consumption.
Built environment and parking pricing: Probability on changing mode choice in Bandung urban area
Authors: Afalia D N , Rachmat S Y 
Published: November 2020

Abstract
Bandung as an urban area in the centre of Metropolitan Bandung Raya and the centre of various activities generate high movement of trips, especially the movement from commuters. The more trips use motorized vehicles, the more people need parking lots. In consequences, the massive movement using private vehicle and the use of on-street parking causes congestion in Bandung Urban Area because of the increasing of road capacity. Previous research proved that one factor to reduce private vehicle user mode choice behaviour is by having a strong strategy in parking. Hence the parking pricing is one of the most effective parking strategies in influencing driver behaviour. The binary logit regression model is used to identify the behaviours of private vehicle users and to investigate the probability of private vehicle drivers shifting to mass transportation particularly for commuter’s trip. This paper surveyed 200 commuters through revealed and stated preference in Bandung Centre Area. The best model is the model with the highest significance number shown from the Neglekerke R square number. The response keeps using private vehicle and parking in the existing area has the highest significance number which is 0,59. The model from the response is Ln P/1-P = 4.356 -1,550 (X1.1)- 1,279 (X1.2) – 0,01 (X2). The variables in this model are a medium compact area (X1.1), a compact area (X1.2) and parking pricing strategy (X.2). The result can assist decision-makers on all levels to wisely allocate resources to public transportation improvement, and optimization of parking pricing strategy, especially in Bandung Urban Area.

Published: November 2020

Abstract
The development of Indonesian Urban Metro Railway Project has been accelerated in the last decade, concerning on a massive infrastructure investment across the regions. The project requires a smart, sustainable, and reliable system of railway slab track to be adopted considering its life cycle cost and the challenging triple constraints (cost, quality, and time). In general, a slab track system is suitable for the required criteria. Despite the complexity for implementing this system, its ability to withstand a variety of Indonesian’s extreme weather (e.g. heavy rain leads to flooding) and geohazards are likely to be considered in comparison with the conventional ballasted track. Moreover, a maintenance aspect is also entailed in the decision-making process. There are two potential types of this system to be utilised; the difference is devoted to the placement of the anti-vibration system which can be mounted in underneath pc sleepers (type 1) or in rail fastening systems (type 2). However, the costs which are mainly allocated to installation and maintenance can be affected by performance uncertainty associated with these systems. Hence, this paper proposes an approach that can be used to address uncertainty and assist decision-makers for selecting and implementing the proper slab system,

Abstract
Today the world faces the fact that 10 million tonnes of waste, primarily plastic waste, pas through the river. This global issue has become a serious problem that can be resolved with location-based that utilizes remote sensing technology, following recent developments of technology. This study aims to estimate the weight of potential plastic waste at the estuary before it enters the ocean and becomes marine debris. Several parameters are developed based on three main aspects, which are environment as graded by LULC, social aspect as provided by population density using building data, and economic aspect as provided by nightlight from NOAA’s VIIRS. The estimation used raster-based digital numbers processing, by using estimated data and providing weight. As a result, it shows that most of the metropolitan cities such as Jakarta contribute almost 507 tonne of plastic waste per day. For other cities, its generation is directly proportional to the increase in population. This study could become a consideration to synthesize policies, with the fact that massive population density impacts the increasing of the plastic waste generation.
Strategic thinking to improve sanitation in Kampung Pelangi 200, Bandung City: in comparison with Kampung Jodipan-Ksatrian, Malang City
Authors: Fatimah W M , Sarli P W , Soewondo P , Zakiyya N M 
Published: November 2020

Abstract
There are 4.5 billion people in the world who do not have access to safely managed sanitation. As an informal area, basic access to sanitation is also limited as available options for sanitation infrastructure provision is hampered by financial limitations. In 2016, students of Universitas Muhammadiyah Malang conducted a project funded by PT Indana in Jodipan, Malang to provide visual improvement to slum areas by painting the houses with striking colors. Jodipan inhabitants’ attitude and perception toward sanitation has changed over time as now their village has become a tourist destination. Meanwhile in 2018, a project funded by Sanlex was conducted in Bandung to attract more tourists by painting houses in Kampung Pelangi 200 to improve the physical appearance of the village. Kampung Pelangi 200 needs to obtain economic value from the project to provide safely managed sanitation. A cohort study is used to compare characteristics and confirm a suspected association between cause and effect to the desired condition. Factors to be considered include 1) Internal factors, particularly geographical characteristics, and location of the village, as well as local culture and social relationship in between village residents. 2) External factors, particularly the involvement of stakeholders and the weather of the city.
Exploration of creative industry networks: the case of Binongjati knitting community
Authors: Aritenang A F , Iskandar Z S , Safitri P 
Published: November 2020

AbstractThe creative economy is a term used to describe industrial activities that are traditional and innovative. Each creative economic activity in Indonesia has its own uniqueness, and in these activities skills, knowledge, and creativity are transferred through local and national links. The paper argues that the characteristics of similar artists are very different between the two types of industries. This paper aims to examine the business networks developed in the context of creative and informal economy in the production and sale of goods of creative kampongs in Bandung. The case study is the Binongjati, a historical creative kampong that specializes in the production of knitting crafts and related fashion products. This study was conducted by interviewing the key persons in Binongjati and distributing questionnaires to business owners. The study found that business networks in the Binongjati creative kampong are spatially wide and economically established. However, based on the production process, industries significantly relied on their production input to local suppliers. Thus, the industry is fragile to any disruption to the local economy in Bandung. However, there are at least two policy implications that need to be considered: the importance to capture local knowledge and innovation and the creative industry policy that should focus to expand the market by enhancing business network analysis and business database of both supplier and customer.

Published: November 2020

AbstractThe Pasar Lama Area of Serang City is one of the strategic areas of Serang City, based on the Serang City Regional Spatial Plan (RTRW) for 2010-2030. But unfortunately, the existing condition of the area is not conducive, because there are many shop stalls and abandoned buildings, and traditional markets that are not well-ordered. This study aims to compile the design of buildings and areas in the Pasar Lama Area of Serang City with the concept of a new normal life that is responsive to the COVID-19 pandemic, so that the quality of the area increases by its designation as a strategic area of the city, and is expected to become a pilot building that is responsive to a pandemic. This research is important because there have not been many building designs that are responsive to the COVID-19 pandemic, especially in traditional markets, even though the market is a vulnerable location to the COVID-19 transmission cluster. The research method uses descriptive qualitative methods, with data collection techniques through observation, interviews, and study of literature. The redesign of the building focused on the Serang Plaza block IV building which was a former cinema building that was redesigned into a clean market (ground floor and 1st floor) and small business and creative industries gallery, mini cinema, and co-working space (2nd floor). The redesigned part of the area is the pedestrian and the ex-slaughterhouse area, which is a typical culinary centre of the City of Serang, with an open system that rotates morning and evening. The recommendation that needs to be done is to explore a collaborative building management scheme and the area, and before starting construction, it is necessary to examine the condition of the existing strength of the building to be redesigned, so that it can be determined to be rebuilt or only partially.

AbstractImproved understanding of the molecular mechanisms underlying ascending equine placentitis holds the potential for the development of new diagnostic tools and therapies to forestall placentitis-induced preterm labor. The current study characterized the equine placental transcriptome (chorioallantois [CA] and endometrium [EN]) during placentitis (placentitis group, n = 6) in comparison to gestationally-matched controls (control group, n = 6). Transcriptome analysis identified 2953 and 805 differentially expressed genes in CA and EN during placentitis, respectively. Upstream regulator analysis revealed the central role of toll-like receptors (TLRs) in triggering the inflammatory signaling, and consequent immune-cell chemotaxis. Placentitis was associated with the upregulation of matrix metalloproteinase (MMP1, MMP2, and MMP9) and apoptosis-related genes such as caspases (CASP3, CASP4, and CASP7) in CA. Also, placentitis was associated with downregulation of transcripts coding for proteins essential for placental steroidogenesis (SRD5A1 and AKR1C1), progestin signaling (PGRMC1 and PXR) angiogenesis (VEGFA, VEGFR2, and VEGFR3), and nutrient transport (GLUT12 and SLC1A4), as well as upregulation of hypoxia-related genes (HIF1A and EGLN3), which could explain placental insufficiency during placentitis. Placentitis was also associated with aberrant expression of several placenta-regulatory genes, such as PLAC8, PAPPA, LGALS1, ABCG2, GCM1, and TEPP, which could negatively affect placental functions. In conclusion, our findings revealed for the first time the key regulators and mechanisms underlying placental inflammation, separation, and insufficiency during equine placentitis, which might lead to the development of efficacious therapies or diagnostic aids by targeting the key molecular pathways.
Can one use Earth’s magnetic axial dipole field intensity to predict reversals?
Authors: Gwirtz K , Morzfeld M , Fournier A , Hulot G 
Published: November 2020

SUMMARY
We study predictions of reversals of Earth’s axial magnetic dipole field that are based solely on the dipole’s intensity. The prediction strategy is, roughly, that once the dipole intensity drops below a threshold, then the field will continue to decrease and a reversal (or a major excursion) will occur. We first present a rigorous definition of an intensity threshold-based prediction strategy and then describe a mathematical and numerical framework to investigate its validity and robustness in view of the data being limited. We apply threshold-based predictions to a hierarchy of numerical models, ranging from simple scalar models to 3-D geodynamos. We find that the skill of threshold-based predictions varies across the model hierarchy. The differences in skill can be explained by differences in how reversals occur: if the field decreases towards a reversal slowly (in a sense made precise in this paper), the skill is high, and if the field decreases quickly, the skill is low. Such a property could be used as an additional criterion to identify which models qualify as Earth-like. Applying threshold-based predictions to Virtual Axial Dipole Moment palaeomagnetic reconstructions (PADM2M and Sint-2000) covering the last two million years, reveals a moderate skill of threshold-based predictions for Earth’s dynamo. Besides all of their limitations, threshold-based predictions suggests that no reversal is to be expected within the next 10 kyr. Most importantly, however, we show that considering an intensity threshold for identifying upcoming reversals is intrinsically limited by the dynamic behaviour of Earth’s magnetic field.
Detailed space–time variations of the seismic response of the shallow crust to small earthquakes from analysis of dense array data
Authors: Bonilla Luis Fabian , Ben-Zion Yehuda 
Published: November 2020

SUMMARYWe compute high-resolution space–time variations of subsurface seismic properties from autocorrelation functions (ACF’s) of noise and local earthquakes, recorded by the Sage Brush Flat dense array deployed around the Clark branch of the San Jacinto fault. The resolved temporal changes are referred to as apparent velocity changes because they reflect both nonlinear response and variations of material properties such as cracking and damage. Apparent velocity changes are estimated at four frequency bands (10–15, 10–20, 15–30 and 20–40 Hz) for two local earthquake data sets. In one analysis, ACF’s from P- and S-wave windows of 31 small events with magnitudes below 3.1 are used to compute the apparent velocity variations with respect to the mean ACF of each phase, and we also use the mean ACF of noise data as reference to estimate the changes. In a further analysis, the temporal evolution of properties is computed using moving time windows in continuous waveform over one-hour long data with noise and earthquake signals. The apparent velocity changes and recovery times are frequency dependent and present a strong spatial variability across the array. The resolved changes are larger and recovery time shorter with data associated with higher frequencies. At frequencies larger than 15 Hz, and using the mean ACF of noise data as a reference, the apparent average velocity changes across the array during the passage of the P and S waves from the small local events are 2.5 per cent and 6 per cent, respectively. The apparent velocity changes decrease by one order of magnitude when the earthquake data are used as a reference. The relatively large changes in response to very low ground motion have important implications on nonlinear processes involving degradation and healing of the subsurface material during common earthquake shaking.
