Abstract
Indonesia is one of the nations that is more prone to earthquakes due to its location at the intersection of the Indo-Australian, Eurasian, and Pacific plates. This study aims to find out the vulnerability and final score of the Faculty of Islamic Economics and Business of Islamic State Prof. KH. Saifuddin Zuhri University used the RVS method based on FEMA P-154, where this method is one of the earliest methods used to evaluate the vulnerability of a building, and has a final value limit of 2. If the final score is more than 2, then the building under review has a low vulnerability to earthquakes and vice versa. This building is one of the mid-rise buildings in Purwokerto which was established in 2019. Based on RVS analysis, the final score was 3.6 for the category of concrete moment-resisting frames (C1) and 1.4 for the category of concrete frames with unreinforced masonry infill walls (C3). Thus, the results showed this 6-story building has a vulnerability to earthquakes with a high category of a high probability of damage to level 3 and a very high probability of level 2 damage.

Abstract
The confinement ratio of spun piles manufactured in Indonesia has been a matter of concern since it does not meet the applicable requirements. Additional steel jacketing retrofitting was used to cope with the problem as well as improve the strength of spun pile to pile cap connection. A numerical study was performed to study the effect of steel jacketing on a spun pile with concrete infill reinforcement. Furthermore, a parametric study was conducted to study the effect of steel jacketing length to spun pile behaviour. Pushover analysis using the Opensees software will be performed with a monotonic loading approach. The results were compared in terms of load – displacement curve, shear and bending capacity, and displacement ductility. It is found that the presence of steel jacketing provides a better behaviour and significantly increases the ductility of specimens. The study also found that a minimum length 1.5D of steel jacketing retrofitting was necessary for better results and remain easily repairable for future concerns.

Abstract
Run-up tsunamis have the ability to pick up debris along their path. More severe damage may result from the debris and their force of impact. Therefore, it is important to analyse the potential for debris in a tsunami-prone area. This study examines the threat of tsunami debris in Cilacap City, especially the source of debris from temporary or non-permanent buildings along the coast of Cilacap City. A site assessment was conducted to observe the existence of non-permanent buildings along with their number and characteristic. The results of the study show that the infrastructure of Cilacap City faces a serious threat from tsunami debris which is source from non-permanent buildings. The material transported by the tsunami run-up to cause debris was maximum 465 tons found in area around Pasir Emas Street cause potential debris for one-meter perpendicular to tsunami run-up direction 503 kg and generate tsunami impact force 28,284.3 N. In addition, the fishing port, Pendem fort and Pertamina oil refinery are also potentially affected by tsunami debris because each location has a significant number of non-permanent buildings.
Hydraulic gradient analysis on embankment dam foundation associated with internal erosion

Published: May 2023

Abstract
Internal erosion is susceptible to occur in conditions where there are cracks or pre-formed cavities at the interface between the dam foundation and embankment. The initiation of internal erosion is related to the critical gradient (Ic
) and hydraulic gradient (Ixy
) at a certain position. The addition of repair materials in foundation improvement will change the total head, especially on the dam foundation, so the value of the hydraulic gradient will also change simultaneously from upstream to downstream. This study examines the value of the hydraulic gradient (Ixy
) at certain points on the dam foundation under the condition of foundation with and without improvement. Several scenarios were simulated using Geostudio Seep/W software to get an estimated value of the hydraulic gradient. The upstream blanket foundation improvement method increases the hydraulic gradient in the upstream zone when compared to the curtain grouting method, thereby increasing the potential for internal erosion in a related area. Increasing the depth of curtain grouting from 25 m to 35 m does not significantly reduce the value of the hydraulic gradient in the dam foundation. Research results can be used for analysis to improve design and construction, and as a reference for similar dams.

Abstract
This research was conducted to reinforce the sheet pile located on the embankment of the Ciliwung Lama river – Inspection Road (RSCM) in Central Jakarta. The road is beside the riverbanks of the collapsed river for 40 m and the position of the sheet pile that slopes towards the river. Based on field observations and analysis of the stability of the slopes carried out, the road’s collapse was not due to the unstableness of the embankment but due to the inability of the sheet pile to receive lateral soil pressure. The research method used Plaxis 2D Software to analyze the reinforcement applied to the sheet pile in withstanding lateral soil pressure. The planned reinforcement of the sheet pile uses a Strauss pile with a sling and ground anchor. In retrofitting, using a Strauss pile, a diameter of 0.4 meters, a length of 9 meters, and a sling with a diameter of D32 with a distance between slings of 2.5 meters. Ground Anchor retrofitting is planned to be 27 m long, 159 mm in diameter, and 88 mm in body grout. Compared to the Safety Factor that occurs between the Strauss pile with the sling and the ground anchor, the safety factor of the Strauss pile with the sling is greater. The Strauss pile’s safety factor was obtained by 1.75, while the ground anchor safety factor was 1.55 without considering the earthquake load.
Understanding of flow liquefaction in Lolu Village based on seismic refraction tomography method
Authors: Andika P P , Tohari A , Yudistira T , Soebowo E , Arifin J 
Published: May 2023

Abstract
A big earthquake may induce flow liquefaction phenomena in lowland areas made up of sedimentary deposits. To understand the factors controlling such a hazard, it is necessary to have knowledge of the sub-surface geological conditions of the liquified area. This paper presents the results of a series of seismic refraction measurements in Lolu Village where flow liquefaction occurred during the 2018 Palu-Donggala earthquake. The results of seismic refraction tomography indicate the presence of horst-graben structures, probably associated with the localized pull-apart basin. The results of this study suggest that the sub-surface geological structure is also a governing factor for the occurrence of flow liquefaction phenomena in an area with a complex fault system.

Published: May 2023

AbstractIn hydro-meteorological studies, precipitation is an important parameter that is utilized in irrigation system design and management, as well as agricultural planning. Under the effects of climate change, precipitation is predicted to alter, which will have an impact on sustainable development. Using rainfall data for the Indravathi subbasin, Godavari basin, from 1998 to 2016, the spatial variability and temporal trend of precipitation were examined over the region, which has a humid tropical climate. Using non-parametric tests like Mann-Kendall (MK) and Sen’s slope approach, analysis for trend detection was conducted. The test data were loaded into ArcGIS software, which then performed monthly, seasonal, and annual analyses of the spatial and temporal trends of rainfall. According to an analysis of the monthly rainfall trends, February had the largest spatiotemporal declining trend in rainfall, while September had the highest spatiotemporal increasing trend. An analysis of seasonal rainfall data revealed a considerable increase in the tendency for summer rainfall over nearly 80% of the basin. Data on annual precipitation revealed an increase in annual precipitation for the basin’s central eastern sections. The findings of this research may help the decision makers and stakeholders make the most efficient use of hydrological resources by providing insight on the effects of climate change and climatic changes on precipitation patterns in the Indravathi subbasin.

Abstract
An extreme occurrence within the earth’s system that causes human fatalities, injuries, and property destruction is referred to as a “disaster” from a social perspective. Disaster management is one of the most critical topics around the world. Many countries are getting affected because of its high magnitude impact on economy and loss of life. The Karnataka government must always be on guard and ready to meet problems due to the frequent natural disasters like landslides, floods, droughts, and human-induced dangers. In order to lessen the effect of disasters on the community, the Government of Karnataka has built enhanced institutional structures for disaster risk reduction. The main aim of the review paper of this, is to create awareness about the situations occurring due to any form of disasters and to develop preparedness in younger generation to face disaster situations.
The pattern of material supply chain in post-disaster reconstruction: a case study in Indonesia’s disaster-prone area

Published: May 2023

Abstract
The government, the community, or non-governmental organisations can all participate in the reconstruction process after a disaster. The management of material procurement and logistics may entail participation from several stakeholders. It may be crucial to a project’s success in reconstruction. A reliable supply chain is required to guarantee an appropriate building supply. The supply chain for building materials significantly impacts the course and results of reconstruction after a disaster. This study intends to map the post-disaster restoration process’s formation of the construction supply chain pattern. In order to detect potential issues and disturbances that could contribute to the failure of the post-disaster restoration process, the supply chain pattern for building materials is being mapped. The path of the supply chain for construction materials is undoubtedly significantly impacted by post-disaster environmental circumstances. Because it can impact project prices and timelines, the choice of building material suppliers is crucial in construction supply chain management. During the reconstruction process in disaster-affected areas, this research used qualitative approaches by conducting surveys and questionnaires to gather data and facts.

Published: May 2023

Abstract
Cost estimation is an important element in a project. In the early stages of a project, information for estimates tends to be less accurate. Therefore, a cost estimation model is needed that can explain most of the projects based on the lack of information. The estimation method used is the Cost Significant Model. The aim is to determine the accuracy of the Strauss Mast Retaining Wall Work cost estimation model against the actual project cost. Data was collected using the sampling method, and 5 (five) similar project packages were obtained from 2019-2021. Produce 2 (two) Significant Cost Items that have cumulative costs (80%), namely Strauss Pile Work (X3) of 32% and Pile Work (X4) of 48%. Then it is analyzed to produce a regression equation formula using the SPSS application, and the equation is Y = 5696.59+5.270 X3-1,389X4 with a Cost Model Factor of 1.11. Estimated accuracy ranges from -7.3% to +8.4%. With an average of +0%. The accuracy rate is in class 1 of the International AACE classification, which has a lower limit of -3% to -10% and an upper limit of +3% to 15%. The estimation model is feasible to use to check the bid estimate.

Published: May 2023

Abstract
Housing reconstruction is a significant determinant of the post-disaster recovery process and one of the most complex challenges, especially in developing countries. Post-disaster housing reconstruction sometimes results in poor environmental quality, delayed construction completion, low performance, and wasteful materials. Previous research has shown the success of the lean application in construction projects as well as in reconstruction projects. Its means that post-disaster housing reconstruction can also apply lean principles and techniques. This study aims to identify and analyze lean theories and techniques that can be implemented to overcome, minimize or resolve problems in Indonesia’s post-disaster housing reconstruction stage to obtain a lean model (Lean Housing Reconstruction). This study is the initial stage of developing a lean implementation model in post-disaster housing reconstruction. A systematic literature review (SLR) was conducted to obtain lean principles and techniques for post-disaster housing reconstruction. The results of the SLR obtained five lean construction techniques that can be used for housing reconstruction, including Lean Six Sigma, Last Planner System, 5S (Sort, Straight, Shine, Standardize, and Sustain), Value Stream Mapping, and Pull Scheduling.

Abstract
These days, metal matrix composites (MMCs) are frequently investigated by incorporating the proper reinforcement particles. In order to enhance various properties of the manufactured MMCs, reinforcement particles are embedded into the base metal. In the present investigation, A356 MMCs reinforced with 5 wt% of zirconium silicate (ZrSiO4) particles have been prepared and tested for the friction and wear behaviour. Utilizing the stir-casting technique, the composites were produced; and the test specimens have been prepared with ASTM G99 standards. Three significant process variables have been considered for performing the wear test such as normal load, sliding velocity and sliding distance. The Taguchi’s L9 orthogonal array design has been used to plan the experimental design for the wear test. Main Effect Plots (MEPs) have been drawn for the coefficient of friction (COF) and wear rate values obtained during the test for different combinations of selected input variables, and analyzed. To determine the optimal input variable combinations that lead to lower COF and wear rate, Grey-Fuzzy Reasoning Grade Analysis (GFRGA) has been used. For the taken into account input conditions and the recorded output responses, an artificial neural network (ANN) model has been created. The surfaces of the worn out samples have been tested with the aid of the micrographs taken by a Scanning Electron Microscope (SEM).
Peer or Parent: The Role of Adolescent Children of Local Authority Foster Carers
Authors: Pratchett Rebecca C 
Published: May 2023

Abstract
When I was sixteen years old, my parents became local authority foster carers. There is no legal recognition of the role that older children play in the care of younger foster siblings. We are not recognised as carers and yet are often involved in providing care and supervision of younger siblings. There are recorded benefits to being a foster sibling, but there are also challenges that come with the role. Within this reflective narrative piece, I seek to trigger a discussion within the field around the role that young adults play in the fostering process. I use my own experience to raise key issues around the safeguarding of not only young people who are looked after but also those whose parents choose to foster. In doing so I aim to open debate around the responsibilities of practitioners to recognise and adequately prepare young adults for the role they will play in a fostering household.
Expectation violations produce error signals in mouse V1

Published: May 2023

Abstract
Repeated exposure to visual sequences changes the form of evoked activity in the primary visual cortex (V1). Predictive coding theory provides a potential explanation for this, namely that plasticity shapes cortical circuits to encode spatiotemporal predictions and that subsequent responses are modulated by the degree to which actual inputs match these expectations. Here we use a recently developed statistical modeling technique called Model-Based Targeted Dimensionality Reduction (MbTDR) to study visually evoked dynamics in mouse V1 in the context of an experimental paradigm called “sequence learning.” We report that evoked spiking activity changed significantly with training, in a manner generally consistent with the predictive coding framework. Neural responses to expected stimuli were suppressed in a late window (100–150 ms) after stimulus onset following training, whereas responses to novel stimuli were not. Substituting a novel stimulus for a familiar one led to increases in firing that persisted for at least 300 ms. Omitting predictable stimuli in trained animals also led to increased firing at the expected time of stimulus onset. Finally, we show that spiking data can be used to accurately decode time within the sequence. Our findings are consistent with the idea that plasticity in early visual circuits is involved in coding spatiotemporal information.
Revised structure model of norovirus-binding fucoidan from Undaria pinnatifida: oligofucose chains branch off from a β6-galactane
Authors: Hanisch Franz-Georg 
Published: May 2023

Abstract
Fucoidans are discussed as antiviral agents, and fucoidan from Undaria pinnatifida (UpF), in particular has gained interest as potential food additive in antinoroviral strategies. As the competitive blocking activity of antinoroviral agents increases with the valency of terminal nonreducing fucose on the competitor, an effective processing of fucoidans to inhibitory oligosaccharides will depend on basic structural features of the polysaccharide. We demonstrate increased antiviral binding activity of processed low-mass UpF generated by hydrothermal degradation contrasting with decreased efficacy of low-mass fucoidan from Fucus vesiculosus. As this finding is in conflict with current structural models of UpF, we undertook a re-investigation of the glycan backbone in UpF. Applying solvolytical desulfation combined with enzymatic cleavage of low-mass fucoidan by endo-β6-galactanase and terminal labeling of oligosaccharides by deutero-reduction and bis-5-phenyl-3-methyl-1-pyrazolone (PMP) substitution, evidence from mass spectrometry and methylation linkage analysis of the oligosaccharides indicates that fucoses and galactoses in the glycan backbone are organized in homomeric blocks, where oligo-fucoses branch off from a galactane-type core: Fuc(1-3Fuc)n1-3[Gal(1-6Gal)n1-6]Gal(1-6Gal)n.
The association between social functioning and health literacy among rural Southeastern African Americans with hypertension

Abstract
African Americans living in low socioeconomic circumstances are at high risk of poor health outcomes; this is particularly true for those with hypertension. Many African Americans with chronic hypertension living in the rural impoverished Southeastern USA have low health literacy and are socially isolated. These factors are known to have a negative impact on health outcomes, but it is possible that social support may overcome some of the effect of low health literacy. Since little has been reported about this association, we examined the association between social functioning and health literacy in a rural African American population in the Southeast USA. We used baseline data from participants in the Southeastern Collaboration to Improve Blood Pressure Control, a pragmatic trial that recruited rural African Americans with persistently uncontrolled hypertension and collected survey data. Overall, 33.5% of the 1221 person sample reported social isolation, 26.0% reported low instrumental support, 36.0% reported low emotional support, and 63.4% had inadequate health literacy. All three domains of low social functioning were significantly associated with low health literacy, and this effect was robust to multivariable adjustment for sociodemographics and cognitive functioning for social isolation (adjusted odds ratio 1.62, 95% confidence intervals 1.20–2.20). In conclusion, the majority of this sample living in the NC and AL Black Belt had high social functioning but inadequate health literacy. Tests of interventions to improve social support, especially social isolation, may be warranted to overcome low health literacy in this high-risk rural population.
