This paper presents the numerical analysis using finite element modelling to observe the stability of embedded and surficial strip footings at the edge of the slope top. This study aims to develop the bearing capacity estimation for strip footing constructed at the top of the slope. Several variations in footing depth, dimension, slope inclination, and internal friction angle exist. Some important outputs are presented, including bearing capacity analysis, a global factor of safety (FS), and a displacement contour. Furthermore, the multivariate adaptive regression spline (MARS) is analysed to determine the model to predict the bearing capacity of strip footing. The results showed that a deeper strip footing depth has a larger bearing capacity and FS. The result also showed that based on MARS analysis, the equation considered four parameters could be implemented to predict bearing capacity analysis of strip footing at the edge of the slope top. In general, this study could contribute to developing a strip footing design for a specific case.
Landslides are an example of severe natural disasters that occur worldwide and generate many harmful effects that can affect the stability and development of society. A better-quality susceptibility mapping technique for the landslide risk is crucial for mitigating landslides. However, the use of assemblages of multivariate statistical methods is still uncommon in Indonesia, particularly in the Kepahiang Regency of Bengkulu Province. Therefore, the objective of this study was to provide an improved framework for creating landslide susceptibility map (LSM) using multivariate statistical methods, i.e., the analytical hierarchy process (AHP) method, the simple additive weighting (SAW) method and the frequency ratio (FR) method. In this study, we established a landslide inventory considering 15 causative factors using the area under the curve (AUC) validation method and another evaluation technique. The performance of each causative factor was evaluated using multicollinearity and Pearson correlation analysis with regression-based ranking. The LSM results showed that the most susceptible areas were located in the districts of Kabawetan, Kepahiang, and Tebat Karai. The high landslide risk in these areas could be attributed to the slope conditions in mountainous regions, which are characterized by high annual rainfall and seismic activity. The AUC training values of the AHP, SAW, and FR methods were 0.866, 0.838, and 0.812, respectively. Then, on the validation dataset, the AHP method yielded the highest AUC value (0.863), followed by the SAW (0.833) and FR (0.807) methods. Moreover, the AHP method provided a higher accuracy value, which suggests that the AHP method is more suitable than the other methods. Therefore, our research indicated that all algorithm methods generate a positive impact and greatly improve landslide susceptibility evaluation, especially for the preparation of landslide damage assessments in this study area. Finally, the method proposed in this study could improve the feasibility of LSM and provide support for Indonesian government decision-makers in arranging hazard mitigation measures in the Kepahiang Regency, Indonesia.
Societal Impact Statement Rafflesia is the genus that contains the world's largest flowers. Despite their global appeal, most of the 42 known species are now at risk of extinction. Urgent action is needed to protect these remarkable flowers. A combined approach to conservation is recommended, including a greater level of habitat protection and support for local community action groups. Rafflesia is a suitable new icon for conservation in the Asian tropics. Summary The genus Rafflesia , which includes the world's largest flowers, has aroused curiosity among scientists for centuries and features prominently in local culture across Southeast Asia. The plant has long been used in ethnobotanical medicine and, more recently, as a source of revenue from ecotourism. But despite its acclaim, Rafflesia remains poorly understood in many respects. Taxonomy is disputed, new species are described each year, and the plant has proven recalcitrant to cultivation. This has hindered conservation, and most of the 42 known species are now severely threatened, yet only one is listed by the International Union for Conservation of Nature (IUCN). We estimate that 60% of Rafflesia species face a severe risk of extinction (equivalent to Critically Endangered [CR]). Moreover, we predict that at least 67% of known habitats fall outside protected areas, exacerbating their vulnerability. Alarmingly, recent observations suggest taxa are still being eradicated before they are even known to science. We present recent scientific discoveries and probable extinctions and highlight case studies of conservation success, with a focus on the role of local people. We propose a multi‐pronged conservation approach combining strengthened taxonomy, ex situ propagation, ecotourism, and an extension of protected areas. We suggest action devolved to local communities and awareness campaigns linked to social media networks will be crucial outside of protected jurisdictions. Finally, we propose to establish Rafflesia as a new icon for plant conservation in the Asian tropics. A combined approach might just save some of the world's most remarkable flowers, most of which are now on the brink of being lost.
In the new Normal era which is filled with uncertainty and ambiguity termed Volatility, Uncertainty, Complex, and Ambiguity, leaders of public organizations are faced with various contradictory conditions (paradoxes) especially to prepare the organization and its employees to change to become more effective and efficient in serving the community. For this reason, a paradoxical leadership style is needed that uses the integration of paradoxical things to meet the needs of the organization and the needs of employees simultaneously. In addition, public organizations are also required to learn to be ambidextrous, that is, to be able to exploit all potentials and resources 'currently' at once. simultaneously exploring and adapting to changing 'future' conditions. The readiness of employees to change is also an important factor to deal with change. In the end, it is hoped that organizational performance can improve and be more adaptive to change.

Financial inclusion remains a critical priority in poverty alleviation efforts (Bongomin, et al., 2018). G20, APEC, AFI, OECD, and ASEAN forums have recognized financial inclusion as an essential strategy to reduce income disparities and improve social welfare (www.kemenkeu.go.id). When people have access to financial services, they can manage their economic life more efficiently and are less vulnerable to financial shocks (Demirguc-Kunt, et.al.,2015). The level of financial inclusion in Indonesia has improved to 85.1% based on the 2022 National Survey of Financial Literacy and Inclusion, a 7.1% increase from 2019. However, the financial inclusion index is not evenly distributed across every province, indicating a lack of financial literacy and awareness in certain regions (Dixit and Ghosh, 2013). Financial literacy is critical to building a financially inclusive society as it provides individuals with financial skills and knowledge to make effective financial decisions (Mindra and Moya, 2017). It allows individuals to plan their finances effectively and make rational financial decisions (Kurihara, 2013). Unfortunately, only 49.6% of the Indonesian population has sufficient financial literacy, according to the 2022 national survey.

This study takes a different approach than previous research, namely the cognitive and affective attribute models. This model has been empirically tested in terms of online repurchase intentions (Fang et al., 2016), tourist destination image (Garay, 2019), and funder intentions to support crowdfunding projects (Liang et al., 2019). Cognitive and affective attribute models are dynamic and parsimonious, with cognitive and affective attributes determined by situational conditions rather than absolute determination. These situational characteristics differentiate the cognitive and affective attribute models from other models such as the technology acceptance model and the unified theory of acceptance and use of technology. This study determined the perception of usability as a cognitive attribute and how people think about a telemedicine app's visual appearance and reputation as an affective attribute. Previous research on cognitive and affective models in the context of telemedicine is still scarce. As a result, this research is novel and contributes to the advancement of marketing science, particularly consumer behaviour in telemedicine applications. This study also makes a few suggestions for businesspeople who offer telemedicine services on how to make them more accepted, known, and trusted by the public. Keywords: Telemedicine, Perceived Usability, Visual Appearance, Reputation, Trust
E-commerce companies such as Tokopedia during the Covid-19 outbreak are vying to provide the best service for consumers. For example, they try to provide free shipping promos,discount, give away, quizzes with prizes and so on, they even still use this strategy until now entering the Post-Covid-19 Pandemic period.However, in providing promotional offers to attract consumers to visit e-commerce This is not a major factor in determining whether consumers will buy the products or service offered, because many other similar platforms also do the same thing and maybe it will be even more tempting for consumer. Therefore, it will be better for e-commerce to focus more on providing satisfaction that can lead to purchasing decisions and make them loyal (Tobagus, 2018). Providing quality service to satisfy consumers is what all e-commerce aims for, because if the consumer is satisfied with the product purchased and the service obtained it will bring profit to the e-commerce and can survive in today's increasingly fierce competition. So, it is hoped that in the future it will provide profound contributions and benefits related to influence Overall E-service Quality to Online Customer Satisfaction on the Tokopedia marketplace which was researched and reviewed after the Covid-19 Pandemic. From the results of this research later, it is expected to emerge new indicators which will open the researcher's discourse regarding variables of E-service quality and Online Customer Satisfaction on online shopping platforms. Researchers estimate that there will be demands for different service standards when shopping using Tokopedia E-commerce before the Pandemic and after the Covid-19 Pandemic.

Tourism has faced several major health crises in recent decades, in addition to the COVID-19 pandemic. Several researchers have investigated how the crisis affected the tourism industry. Health crises such as severe acute respiratory syndrome (SARS) have been regarded as a temporary tourism crisis, having a significant impact on China's and ASEAN's tourism industries (Tran et al., 2020). Aside from SARS, avian influenza has had a significant impact on tourist arrivals in Asia (Kuo et al., 2009). Hand, foot, and mouth disease (HFMD) has also been shown in studies to have a negative impact on tourism demand in the European region (Blake et al., 2003). Previous research has focused on dengue fever, Ebola, yellow fever, and malaria outbreaks, with an emphasis on the negative impact on tourist arrivals in affected countries (Novelli et al., 2018; Oduber et al., 2014; Rossello et al., 2017). During this health crisis, changes in tourist behaviour are expected to decrease. Because the COVID-19 pandemic is still in its early stages, there is a need to investigate how travellers behave in response to the pandemic and how it will affect their travel behaviour. Based on these considerations, this study seeks to investigate tourist behaviour following the Covid-19 pandemic and its implications for future travel intentions. In predicting personal behaviour principles, this study employs Ajzen's TPB (1985) concept. The TPB was founded on the theory of rational action (TRA) and included additional predictors such as perceived behavioural control and subjective attitudes and norms. As a result, attitudes, subjective norms, and perceived behavioural control are well-established predictors of behavioural intention. Because TPB has been widely used in fields such as psychology, marketing, and tourism, to name a few, other researchers have attempted to incorporate risk predictors into models in order to increase their explanatory power (Han et al., 2010).

The growth of investment in Indonesia is developing so quickly, as can be proven by the existence curve from the Investment Coordinating Board (BKPM) notes that both investment realization of Foreign Investment (PMA) and Domestic Investment (PMDN) from year to year during the 2015-2019 period continued to increase. This has an impact on the company so as to make intense competition between companies. Every company must develop its competitive advantage in order to survive and advance the company. One of the advantages that companies need to develop is the company's financial performance (Lokollo and Syafruddin, 2013). The ratio analysis used by the company in assessing the company's financial performance is the profitability ratio. Every company has two main goals, namely to maximize profits and maintain liquidity. The purpose of this study is to determine the effect dividend payout ratio, liquidity, firm size and use of debt to profitability (Case study of companies listed on LQ-45). This study wants to analyze the effectdividend payout ratio, liquidity, firm size and use of debt to profitability. An increase in dividend payout indicates the condition and prospects of the company are in good condition, so that it will increase the company's profitability. The higher the liquidity, the more funds the company needs to settle the company's maturing obligations, this of course will reduce the company's profitability. If the level of company size is high, funds are easy to obtain, then the company's operations are smooth and will increase the company's profitability. If the company uses debt as a source of financing to support operations, it will reduce profitability. Keywords: Dividend Payout Ratio, Liquidity, Firm Size, Use of Debt and Profitability.
Cimandiri Fault in West Java is one of the active faults in West Java, Indonesia. The activity of the fault could potentially result in damage to the surrounding areas. This paper presents a study of ground response analysis and the potential seismic damage to structures in sites surrounding the Cimandiri Fault. The site investigation data are collected. Furthermore, ground motion prediction is conducted. To estimate the potential damage, the potential seismic damage is performed. The spectral matching method determines artificial ground motion represented by the investigated sites. The seismic ground response analysis is conducted to observe ground motion parameters and soil response. The results show that the prediction of damage intensity level in the study area is about Scale VIII at maximum. The site amplification during seismic response is observed to vary from 1.4 to 2.7. The results also show that spectral acceleration design is still reliable in covering the effect of spectral acceleration amplification. However, the results also indicate that the trend of spectral acceleration shows that the amplification generally occurs at a medium-long period. It implies that the resonance effect may occur in medium-high-rise buildings.
The global COVID-19 pandemic has presented humanity with difficult and unforeseeable hurdles. Among these challenges is understanding how climate-related aspects impact the survival of the SARS-CoV-2 virus. This study aimed to investigate the relationship between environmental factors, such as temperature, humidity, and rainfall, and the spread of COVID-19 cases in different regions. A time-and-place-based ecological study design was adopted, integrating geographic information systems and statistical techniques. Statistical testing revealed a significant association between humidity (p-value = 0.000; r = -0.777) and rainfall (p-value = 0.001; r = -0.561) with COVID-19 instances. However, no statistically significant relationship was found between temperature variables and COVID-19 cases. Due to the impact of changing weather conditions, governments may become concerned about developing tailored preventive and control measures, considering the varying risk levels associated with different locations.

This paper presents an analysis of the identification of potential seismic damage in an area called Tanah Patah, Bengkulu City, Indonesia. This study is initiated by conducting site investigation and geophysical measurements. Ground motion prediction is conducted to estimate peak ground acceleration which is then used to estimate the damage intensity level during a large earthquake. A spectral matching method to generate ground motion at investigated sites is conducted. Seismic ground response analysis to observe ground response and soil behaviour is performed. The results show that peak ground acceleration in the study area is about 0.255–0.342 g during a large earthquake. IX is this area’s Modified Mercalli Intensity (MMI) level scale. Since sandy soils dominate the study area, several sites could be more vulnerable to undergoing liquefaction. The thickness of potentially liquefiable soils is about 8.6–12.8 m. The results could help local governments develop spatial plans in the study area.
The role of social media has been momentous in COVID-19 vaccine discussions. This study explores the impact of social media interactions on vaccination intention by employing the Stimulus-Organism-Behavior-Consequence theory. We empirically test the proposed framework by surveying 298 social media health group members from India. The study's findings reveal the positive influence of human-to-human interaction on social support and vaccine information exchange and human-to-information interaction on vaccine information exchange. Further, both social support and vaccine information exchange positively influence value co-creation, enhancing vaccination intention. We also test the moderating effect of perceived vaccine efficacy, which adds novelty to this study. This research may be a frontrunner to empirically study vaccination intention in the social media context, an emerging reality. This study's results have meaningful implications for scholars, healthcare practitioners, social media platforms, and governments promoting vaccination.

Pengaruh yang diberikan dua dari tiga variabel independen (electronic word of mouth dan citra destinasi) dalam penelitian ini tergolong rendah. Perlu dilakukan penelitian kembali yang memperhatikan motivasi orang berwisata di masa new normal ini.
Air Putih, Lebong Regency's geothermal field, is near gold mining. The relationship between the two can be illustrated in the type of rock alteration. The study aims to identify the rock alteration zone caused by the Air Putih, Lebong Regency geothermal system. It was described by the correlation of rocks' resistivity and chargebility values based on geoelectric measurement. Two tracks spread along the Air Putih tour, with a track length of 240 meters, were used to see variations in resistivity and chargeability values and the depth of geothermal potential due to deeper current penetration to determine the alteration zone in the study area. The results of field measurements are in the form of 2D models processed with Res2DinvX64 software. According to analysis, the subsurface rock lithology in the research area is relatively the same because the location of the two measurement lines is still close together; namely, there are wet valley rocks and alterated rock layers. Pores cause rock layers found in conductive areas in the rock filled with fluid or water at high temperatures. It is evidenced by the detection of manifestations on the surface in the form of warm soil, warm rocks, steamy soil, and small holes containing water grains. The higher the temperature and pressure, the lower the value of rock-specific resistance. At the Air Putih tourist area of Lebong Regency, it is found that it is a zone of prophylitic alteration containing several minerals of andesite lava, breccia, tuff, and soil.
Besides adenovirus, pneumonia can also be caused by bacteria. One of the most common bacteria causing the pneumonia is Klebsiella pneumoniae. Currently, treatment by antibiotics has been widely used. Nevertheless, the increasing failure of existing antibiotics because of antibiotic resistance resulted by bacterial pathogens has become a serious problem to human health. Hence, there is a need for a new antibacterial potential agent against K. pneumoniae as an alternative treatment to the pneumonia to prevent the risk of a severe pneumonia for both healthy people and those already infected with the pneumonia. This study, therefore, investigated the antibacterial activity of some selected plants (Pandanus tectorius, Nypa fruticans, Sonneratia alba, Phaleria macrocarpa, Hibiscus tiliaceus, and Pongamia pinnata) against K. pneumoniae. In this study, samples were extracted successively by cold maceration using hexane and methanol. Antibacterial activity was determined by well and disc diffusion methods. Each fraction was prepared by two-fold dilutions from 20 mg/mL to 0.156 mg/mL. All data were analyzed in triplicate replication and presented as mean values ± standard deviation. Results showed that all methanol fractions of selected plants had antibacterial activity against K. pneumoniae, and well-diffusion method showed better antibacterial results compared to the agar well-diffusion method. The strongest activity was obtained by methanol fraction of S. alba leaf, followed by P. pinnata leaf, Nypa fruticans bark, H. tiliaceus leaf, P. macrocarpa leaf, and P. tectorius leaf with the minimum inhibitory concentrations (MICs) value between 0.625 and 5.0 mg/mL. Phytochemical screening revealed that all methanol fractions were rich in flavonoid content, which could have contributed to their antibacterial activity.
This research is a study of cultural expressions (oral traditions) which aims to describe traditional expressions of the Pasemah Bengkulu ethnicity as a means of social control in society. The research method used is a descriptive ethnographic approach. The research data is in the form of traditional expressions of the Pasemah Bengkulu ethnic community which were obtained through observation and or recording from a number of informants intentionally or not. The research procedure follows the steps proposed by Spradley (1997). The results of the study are seen from the meaning, communication situations, speakers of the other party, and ways of expressing anger. Expression of anger is a means to express feelings of annoyance, disappointment, and dislike. Expressions of anger can be a means of therapy for speakers and interlocutors for the emotions they experience and are one of the cultural images of the Pasemah Bengkulu ethnic community. In addition, the expression of anger is also a form of social control for society as well as a recorder of taboo vocabulary.
