Authors: БЕЛАШ Татьяна Александровна , СМИРНОВА Любовь Николаевна , БУБИС Александр Александрович , ЗВЕЗДОВ Андрей Иванович
Published: December 2023

В настоящее время в практике сейсмостойкого строительства сложились определенные подходы к повышению и восстановлению сейсмостойкости эксплуатируемых зданий и сооружений, среди которых все более популярными становятся конструктивные решения в виде систем сейсмоизоляции и сейсмогашения. Системы сейсмоизоляции получили конкретное воплощение в ряде зданий на территории РФ. Однако для дальнейшей успешной реализации этих систем защиты следует учитывать определенные особенности их применения на основе уже сложившегося опыта строительства и эксплуатации. Отмечена необходимость проведения комплекса предварительных работ, включающих в себя оценку сейсмологической обстановки, состояния конструкций зданий и сооружений, их оснований, а также совокупности других факторов. В случае реализации усиления строительных объектов с помощью специальных средств сейсмозащиты следует тщательно разрабатывать проекты производства и организации работ на строительной площадке.

Authors: СТЕПАНОВА Валентина Фёдоровна , РОЗЕНТАЛЬ Николай Константинович , МОИСЕЕВА Надежда Анатольевна
Published: December 2023

Катодная электрохимическая защита металлических и железобетонных конструкций от подземной, надземной и морской коррозии используется на этапе ремонта сооружений и в процессе эксплуатации. Однако широкого применения в настоящее время этот метод не получил, во многом из-за недостаточного обоснования эффективности его использования. Цель работы - оценка целесообразности применения разработанного преобразователя для катодной защиты арматуры в железобетонных конструкциях. Проведены натурные испытания четырех железобетонных опор автомобильного моста, находящихся в области воздействия блуждающих токов (железнодорожные пути). Для лабораторных исследований были изготовлены бетонные образцы, армированные стальными стержнями. Испытания заключались в выдержке в коррозионной среде образцов, находящихся под катодной защитой и без нее. Доказано обеспечение поддержания защитного потенциала арматуры посредством разработанного преобразователя для катодной защиты. Выполненный экономический расчет на примере плиты перекрытия подземного паркинга здания показал целесообразность применения катодной защиты арматуры, как на стадии проектирования, так и на этапе ремонта.

SETIATI SURASTO DALAM PERJUANGAN BURUH PEREMPUAN PADA 1940AN-1960AN
Authors: WULANDARI AYU
Published: December 2023

This research discusses the views and roles of Setiati Surasto in improving the fate of women labour between the 1940s and 1960s. This study stems from companies’ or employers’ discrimination that always considers female labour as cheap labour from time to time. Women labour were seen as unskilled workers, feasibly exploited and not appreciated. Consequently, women labour experiences discrimination in various forms, ranging from wages to violations of their rights. This study used historical research methods in which newspapers and magazines were primary sources. The findings indicate that the inequality that they experience generates women’s agency and activism. Setiati Surasto was one of the activists who voiced her views on equality and welfare for women labour through writing and direct action. This research has filled the gaps in Indonesian historiography, especially by presenting the biography of a women’s labour activist during the early period of Indonesian independence.
PERNIKAHAN BUGIS-MELAYU DAN CIKAL BAKAL GELAR BARU KEBANGSAWANAN DI KERAJAAN JOHOR RIAU

Published: December 2023

Internal conflict in the struggle for power within the Kingdom of Johor in the 18th century involved the Bugis people in the area. The Upu Daeng Brothers earned the Yang Dipertuan Muda (YDM) in the Kingdom of Johor, married Malay nobles and the sultan's sister after they successfully conquered Raja Kecik. Accordingly, these situations led to the disappearance of Bugis person’s identity. In other words, Bugis descent who marry Malays no longer bear the name Daeng but Raja. The study employed historical research methods applying heuristics, source criticism, interpretation, and historiography, in which the data analysis was from the perspective of the cultural identity approach. This research revealed that the Bugis descent who lived and settled in the Johor Riau Kingdom since the 18th century were known as Bugis Malays. The new identity was due to the title 'raja,' bestowed upon the Bugis who married the Malays. The use of the new title began with the involvement of Bugis descendants in government and marriages between Bugis and Malay aristocrats.

Authors: Yusuf Nur Fadilah
Published: December 2023

The article provides a detailed account of the development of Tanjung Priok Port, from its establishment in 1883 to when it was equipped with a station in 1925. The port was built in response to the opening of the Suez Canal in Egypt, which significantly impacted the maritime development of Europe to the Far East, including the Dutch East Indies. The rapidly growing shipping activities, which relied on sea routes, could no longer be accommodated by the Sunda Kelapa Harbour. Consequently, the government decided to construct Tanjung Priok port. This study uses a historical method that includes heuristics, source criticism, interpretation, and historiography. The author discusses various aspects of Tanjung Priok Port, namely the construction process, the port's condition, development, and supporting elements. Additionally, the article covers the port activities before the formal institutional establishment of Tanjung Priok Port

Authors: Gerry Suryosukmono  , Bambang Sahono  , Muhammad Yasser Iqbal Daulay  , Ilsya Hayadi  , Chairil Afandy
Published: December 2023

This research aims to measure the role of toxic leadership which is reinforced by boss phubbing behavior as a moderating variable which negatively influences employee behavior and triggers the employee's desire to leave an organization. We use a sample from 305 employees of private companies and work for both industrial and service companies in Indonesia. The method was carried out by conducting a pre-test using Confirmatory Factor Analysis to determine validity and reliability. Furthermore, this research describes the respondent's profile and tested the hypotheses using the Structural Equation Modelling (SEM) method. The results showed that there was a significant, direct effect from the influence of toxic leadership on job stress, perceived leader integrity, and meaningful work. These three variables also had a significant effect on turnover intention. Moreover, boss phubbing also managed to moderate the relationship between toxic leadership and job stress, perceived leader integrity, and meaningful work. The research is unique because no empirical research before tries to examine the relationship between toxic leadership and Boss phubbing as a supporting element for the emergence of negative behavior for employees.
COMPARATIVE PERFORMANCE OF ARIMA, SARIMA AND GARCH MODELS IN MODELLING AND FORECASTING UNEMPLOYMENT AMONG ASEAN-5 COUNTRIES
Authors: Kuang Yong Ng  , Zalina Zainal  , Shamzaeffa Samsudin
Published: December 2023

Unemployment, especially after the COVID-19 pandemic, is a critical issue for any country as it has economic and social ramifications. Consequently, forecasting unemployment becomes an essential task as it can guide government policy. Time series data are frequently influenced by outliers (unexpected events), and some outliers may exist with extreme observation to reduce the forecasting effectiveness of robust estimators. This study compared the performance of Autoregressive Integrated Moving Average (ARIMA), Seasonal Autoregressive Integrated Moving Average (SARIMA) and Generalised Autoregressive Conditional Heteroscedasticity (GARCH) models in modelling and forecasting unemployment rates during the COVID-19 pandemic among the ASEAN-5 countries. These countries include Malaysia, Singapore, Thailand, the Philippines and Indonesia. The monthly unemployment data from January 2010 to December 2021 were applied for all cases, except Thailand, until December 2020. Each adequate model from both forecasting mechanisms underwent forecasting. Their performance was compared based on root mean squared error (RMSE), mean absolute error (MAE), Theil inequality coefficient and symmetric mean absolute percentage error (SMAPE). Static forecasting from the ARIMA and SARIMA models was found to perform better than the GARCH model in modelling and forecasting the unemployment rate among ASEAN-5 countries during the pandemic period.

Authors: Herning Indriastuti  , Robiansyah  , Hairul Anwar
Published: December 2023

Several people turned or changed to entrepreneurs and established start-ups during COVID-19. Limited access allows them to use the network competence and access market information to improve sales growth. Therefore, this research aims to contribute to a conceptual model of market information accessibility and successful collaboration innovation to ensure start-ups achieve superior sales growth. The analysis results with SEM-AMOS using the normality test resulted in 192 start-ups in Indonesia from the initial data of 280. The results showed that the level of suitability (significant) meets all the requirements and supports the hypothesis. However, market information accessibility and successful collaboration innovation play an important role in mediating the relationship between network competence and sales growth. This research contributes to the body of knowledge in the development of relational marketing theory. Moreover, start-ups’ actors need fast adaptation because their business lasts longer by seeking access to information and collaboration innovation.
IMPACT OF DERIVATIVE WARRANTS INTRODUCTION ON THAILAND STOCK MARKET VOLATILITY
Authors: Woradee Jongadsayakul
Published: December 2023

The Stock Exchange of Thailand (SET) first launched derivative warrants on SET50 index (SET50 DWs) on April 17, 2014. They are currently the most active DWs on the SET. This research uses the GARCH family models augmented with dummy variable to analyze the effect of SET50 DWs on stock market volatility. The sample data consist of daily returns of SET50 index from the period October 30, 2012 to December 30, 2019. The empirical results indicate that the coming into market of SET50 DWs reduces stock market volatility. The GARCH (1,1) TARCH (1,1), and EGARCH (1,1) models are not radically different from each other in their output. However, the asymmetric TARCH (1,1) model is found to provide the best fit in modelling volatility. The SET50 index shows the existence of leverage effect, where negative shocks have a greater impact on the volatility than positive shocks. Introducing SET50 DWs lowers the price volatility of SET50 index so investor having a portfolio investment with a correlation to the performance of SET50 index should adjust hedge ratio appropriately to manage investment risk. There is also a suggestion for policy makers to support the launch of DWs to lower the volatility in underlying spot market resulting in improved efficiency.
ISLAMIC BANKS IN AFRICA: THE RISK OF SHARIA NON-COMPLIANCE AND FINANCIAL PERFROMANCE
Authors: Aishatu Usman Muhammad  , Murni Yusoff
Published: December 2023

The establishment of Islamic banks is solely based on Sharia standards, which, if not followed, will have dire consequences of Sharia non-compliance, making IBs comparable to conventional banks. Sharia non-compliance can damage investor trust and income. Although Sharia is the primary distinction between IBs and CBs, Sharia non-compliance must be scrutinized to avoid non -compliance issues. The risk of Sharia non-compliance and the performance of Islamic banks in Africa are investigated in this research, covering the years 2015 through 2019. The research studied 27 Islamic banking institutions from 11 African countries. The Sharia non-compliance risk was evaluated using the size and competence of the Sharia committee. In addition, GDP, bank age and size were used as control variables. Data were analyzed using simple regression with EViews. The result shows that Sharia Committee Size positively correlates with African Islamic bank performance. The research also shows that the expertise of the Sharia Committee in Sharia positively affects Islamic bank performance. Banks with larger Sharia committees perform better, the studies revealed. All banks have a large number of Sharia specialists in their committees, indicating that having them is vital for establishing and smoothly running an Islamic bank.

Authors: Nguyen Thi Minh Chau  , Vo Xuan Vinh
Published: December 2023

This paper is accomplished to assess the influence of global economic policy uncertainty and globalization on the stability of the banking system in Asian countries. Although the stabilization of the banking system is a subject of great interest to many researchers, there has yet to be research that simultaneously evaluates the influence of these two factors on its stability. simultaneously evaluates the influence of these two factors on its stability. Based on data from Asian countries and the two-step systematic GMM regression method, the research results show that economic policy uncertainty and globalization erode the banking sectors' stability in Asia. Additionally, the study provides evidence that a country's banking system with a high globalization index will be strengthened in an environment of policy uncertainty. Moreover, financial, economic, and political globalization can reverse the influence of global economic policy uncertainty on the banking system's stability. These findings hold significant policy implications for governments, policymakers, and banking managers.

Published: December 2023

The first two males’ mortality in Malaysia due to COVID-19 announced by the authority on March 13, 2020. The fatalities became the major headlines on the media. Although many people discussed ‘actively’ about COVID-19, however conversations about deaths or funerals of victims from COVID-19 are quite ‘passive’ during the initial stage of the pandemic. When death occurs, biomedical examiners must examine death causation, mechanism and manners of death because COVID-19-related deaths are contagious. As a results, corpses are managed by authorised personnel with no or limited intervention from family or community members. These social responses to deaths from COVID-19 are paradox as funerals are traditionally communities’ responsibility. Due to surging cases of COVID-19, drastic measures are taken by the government globally to prevent the spread of COVID-19 and for social, economy and environment sustainability. This study aims to examine COVID-19 mortality patterns and its socio-cultural dimensions in Sarawak. Data are collected in the duration of 18 months from official sources and from participant observation. Data are analysed in several aspects including age, gender and co-morbidity. The findings show that mortality rates among males are significant higher compared to females. Most casualties occurred among age groups: 70-79, 60-69 and 50-59. The majority of cases have co-morbidity.
Space of Belonging: Engaging the State in Borneo
Authors: Langub Jayl
Published: December 2023

The Penan argue that their rights and attachment to the land are more than the mere felling of trees to open up land areas for cultivation to create native customary rights land. Their relationship with the landscape have turned hilltops and depressions between two connecting hills into campsites, thus giving these spaces a sense of residence. Their relationship with their rivers and streams is reflected through the naming of these tributary systems, names that are imbued with rooted histories and events narrated over generations. This paper provides an overview on how the Penan constantly navigate the values governing their ever-changing landscapes brought by external forces. In doing so, it charts the history of Penan struggles with state policies, logging activities, and how they assert their rights to their landscape by engaging with not only the state but also environmental and human rights activists, international non-governmental organisations, and other local grassroots organisations. Engagements with these state and non-state institutions and organisations have enabled the Penan to articulate their identities and rights to their resources. Based on these engagements, this paper argues that the Penan rights and way of life is closely related to particular spaces in the landscape, their space of belonging.
Use Of TikTok Slang Among Malaysian Generation Z
Authors: Marzuki Ernisa , Mustapha Nurul Syafiqah
Published: December 2023

This study examines the usage of TikTok slang among Generation Z. The specific objectives are to 1) determine the perceived frequencies of usage; 2) identify the contexts during which TikTok slang are used; 3) determine how the slang are acquired; and 4) find out the reasons why the slang is used. The participants were 102 Generation Z participants aged 10-25 in Malaysia. An online questionnaire was used to collect data. The results showed that 52% of the participants frequently used TikTok slang in communication but 6.9% never used it. As for sources of acquiring slang, social media was the most influential. Friends are more important than family in spreading use of TikTok slang, mainly because TikTok slang is mostly used among young people rather than adults. Over half of the participants frequently used TikTok slang at school or at work but less during social gatherings, and the least during formal meetings. The main reason for the Generation Z participants to use TikTok slang is for fun (73.5%) but one-third of the participants used slang to be creative, show solidarity with ingroup and to be efficient in communication. The study suggests that TikTok slang has possibly spread from social media use into face-to-face communication in school and work settings.

Authors: Campbell Yvonne Michelle , Charles Fazira Bukas
Published: December 2023

This study explored code-mixing in selected English short stories from Sabah and Sarawak. It examined the types of code-mixing found in these short stories and the basis for these code-mixing. 20 short stories were selected from two anthologies, “Chronicles of KK” and “Short Stories from Sarawak: Death of a Longhouse & Other Stories”. This study applied a qualitative research method, and the data were analysed using Musyken’s (2000) and Hoffman’s (1991) theories. Two types of code-mixing were found in the short stories which are insertion, and alternation, with insertion being the most common type found, especially lexical items from Sabah and Sarawak’s local or indigenous languages. The study discovered that the reason these code-mixing was used was to talk about a particular topic, to clarify the speech content for interlocutor, to express group identity, to repeat something for clarification and as a form of interjection.

The stress background and rock fractures are essential factors affecting the stability of mines. In order to better understand the in situ stress background and rock fractures in the Guangdong Fankou Mine, we use ultrasonic borehole television scanning to measure rock fractures. The results indicate that rock fractures are intensively distributed at depths of −360 m to −450 m below the surface, suggesting the effect of intensive mining activities. The present maximum horizontal principal stress direction is NWW, which is consistent with the regional tectonic stress field direction. Systematic measurement of rock fractures is fundamental for further three-dimensional geological modeling and is significant for mining engineering.

Hydraulic fracturing is an essential technique for reservoir stimulation in the process of deep energy exploitation. Granite is composed of different rock-forming minerals and exhibits obvious heterogeneity at the mesoscale, which affects the strength and deformation characteristics of rocks and controls the damage and failure processes. Therefore, in this paper, based on the discrete element fluid-solid coupling algorithm and multiple parallel bond-grain based model (Multi Pb-GBM), a numerical model of a granite hydraulic fracturing test is established to study the evolution of hydraulic fractures in crystalline granite under different ground stress conditions. The main conclusions are as follows. The crack propagation of hydraulic fractures in granite is determined by the in situ stress state, crystal size, and mineral distribution, and the ground stress is the main controlling factor. The final fracture mode affects the maximum principal stress and shear stress, and the generation of cracks changes the distribution of the stress field. The hydraulic fracturing initiation pressure decreases with decreasing crystal size. The influence of the crystal size on the crack inclination angle is mainly reflected in local areas, and the general trend of the fissure dip angle distribution is along the direction of the maximum in situ stress. This study not only has important theoretical significance for clarifying the propagation mechanism of hydraulic fractures but also provides a theoretical basis for deep reservoir reconstruction and energy extraction.
Intelligent reconstruction for spatially irregular seismic data by combining compressed sensing with deep learning
Authors: Gong Xinyue , Chen Shengchang , Jin Chengmei
Published: December 2023

Data reconstruction is the most essential step in seismic data processing. Although the compressed sensing (CS) theory breaks through the Nyquist sampling theorem, we previously proved that the CS-based reconstruction of spatially irregular seismic data could not fully meet the theoretical requirements, resulting in low reconstruction accuracy. Although deep learning (DL) has great potential in mining features from data and accelerating the process, it faces challenges in earth science such as limited labels and poor generalizability. To improve the generalizability of deep neural network (DNN) in reconstructing seismic data in the actual situation of limited labeling, this paper proposes a method called CSDNN that combines model-driven CS and data-driven DNN to reconstruct the spatially irregular seismic data. By physically constraining neural networks, this method increases the generalizability of the network and improves the insufficient reconstruction caused by the inability to sample randomly in the whole data definition domain. Experiments on the synthetic and field seismic data show that the CSDNN reconstruction method achieves better performance compared with the conventional CS method and DNN method, including those with low sampling rates, which verifies the feasibility, effectiveness and generalizability of this approach.
Research on prediction of slurry migration distance in aggregate stacking based on GA-PSO-BPNN algorithm
Authors: Su Peili , Yang Shu , Li Chong
Published: December 2023

After the water inrush accident in coal mine tunnels, early-stage pouring of aggregate forms a high-resistance, low-permeability aggregate stacking, transforming the pipeline flow into percolation. In the later stage, grouting is carried out into the interior of the aggregate stacking, effectively accumulating and solidifying the cement slurry. Among these, whether the slurry can migrate over long distances and fill the voids inside the aggregate stacking is the critical determinant of the success or failure of sealing. To quantitatively analyze the migration distance of slurry inside the aggregate stacking after grouting, a single-hole grouting test platform was established, and an orthogonal experiment was designed with grouting pressure, water cement ratio, and aggregate stacking porosity as influencing factors. Based on 25 sets of experimental measurements, four neural network prediction models suitable for studying the slurry migration distance within the aggregate stacking were constructed separately as back propagation neural network (BPNN), genetic algorithm (GA) combined BPNN, particle swarm optimization (PSO) combined BPNN, and GA-PSO combined BPNN. Evaluation criteria such as Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), Mean Square Error (MSE), Root Mean Square Error (RMSE), and the coefficient of determination (R2) were used for comparative analysis of the calculation errors and prediction accuracy of each model. From the perspective of neural network prediction results, the weight value of each influencing factor was analyzed, and the ranking was as follows: grouting pressure > aggregate particle size > water cement ratio, with grouting pressure being the primary controlling factor. The study demonstrates that the GA-PSO-BP model exhibits the best prediction performance, with an average relative error of only 1.59% and an R² of 0.998. This neural network model overcomes issues such as slow learning and getting stuck in tricky spots in BP neural networks. The prediction model shows high accuracy and stability, enabling more effective and accurate prediction of slurry migration distances, making it worthy of dissemination and application. This study can improve safety measures by reducing waste, expediting disaster management efforts, and minimizing environmental hazards associated with mining incidents.
An empirical study on the relationship between economic growth and forest carbon sink value based on PVAR model
Authors: Song Yukun
Published: December 2023

The dynamic relationship between the value of forest carbon exchange and economic growth has a significant impact on the sustainable development of China’s economy and society. Hence, the consequences cannot be ignored even when China enjoys a win-win situation concerning environment and development. This study examines the economic growth and forestry data from 1995 to 2020 (2021 data from the Statistical Yearbook of China Forestry and Grassland in February 2023 has not been released) to calculate the forest carbon sink (using the forest stock method), estimate the forest carbon sink price, and establish a panel vector autoregression model. Pulse response analysis and variance decomposition are also used to test the dynamic relationship between economic growth and forest carbon sink value. The study finding reveal that during the research period, economic growth promoted the development of forest carbon sinks; forest carbon sinks “suppressed” economic growth in the short term; and the inhibitory effect of forest carbon sinks is no longer significant. The possible innovations and contributions of this study are: 1) Expanding relevant research on the calculation of the value of forest carbon exchange, using the forest accumulation method to calculate the province’s forest carbon exchange, and using the production function of the number to estimate the price of forest carbon exchange. 2) Based on the requirements of the high-quality development stage of the economy, it can serve as a reference to formulate and improve policies for relevant departments (according to the empirical results), thereby helping the country achieve the “dual carbon” goal as soon as possible.
