Authors: Pratiwi Ade Yuniati , Afriyono Hari , Chairunnisa Nursiah , Krasna Wiku Adhiwicaksana , Nurwidayati Ratni , Fahreza Ahmad
Published: February 2025

This study investigates the performance of modified reinforced concrete (RC) beams with truss systems, specifically Pratt-truss and Warren-truss, compared to typical reinforcement systems through flexural strength tests. Aiming to enhance load-carrying capacity, the use of angle steel profiles in the truss systems to transform standard reinforcement bars was analyzed. The flexural strength evaluation involved eight specimens: two with conventional reinforcement, three with Pratt-truss, and three with Warren-truss, each measuring 15 x 15 x 120 cm. The focus was on initial stiffness, secant stiffness, and ductility. Results showed a notable performance increase with truss systems: a 7.5% rise in average initial stiffness, a 1.2% improvement in secant stiffness, and a 5.7% enhancement in displacement ductility, highlighting their potential for safer and more durable structures. The Pratt truss system exhibited the highest ductility, followed by the Warren truss and the standard system. Experimental observations indicated that the typical reinforcement system initially showed flexural cracks at the bottom of the beam, later followed by diagonal shear cracks, which intensified under load, causing concrete to crush in the compression zone. A similar pattern was observed in truss-reinforced beams, with initial flexural cracks at the beam’s bottom progressing under load, ultimately resulting in concrete crushing in the same area. Crack propagation in both systems involved the formation and expansion of cracks along the diagonal and vertical framework, indicating flexural cracks.

Published: February 2025

The study examined smart learning environments as a pathway to quality university education in Nigeria. The population of the study comprised all lecturers in the four government-owned universities in Bayelsa State. However, the researchers were unable to determine the precise number of lecturers at the time of this investigation due to data collection constraints. Based on the advice of Fox et al. (2007) and Meyer (1979), the researchers chose to adapt 384 samples from a population with an unconstrained range. The data used were collected through an online questionnaire; however, 296 lecturers responded by filling out the questionnaire. The findings reveal that smart learning tools such as projectors, internet facilities, computer-based test, mobile learning devices are readily available, while smart boards, video conferencing tools, digital cameras, and LMS are moderately available. On the contrary, virtual and augmented reality, smart classrooms, and gamification are not widely available, and the majority of the respondents are not familiar with them. There is an increased utilization of internet facilities, computer-based text, projectors, and mobile devices in the teaching processes, while other technologies such as LMS, smart boards, video conferencing tools, as well as virtual and augmented reality, gamification, and smart classes, are still emerging technologies. Lecturers have a positive perception of the utilization of smart learning technologies, noting that lack of adequate funds, lack of adequate electricity supply, and poor internet facilities were some of the major challenges in the utilization of SLE. Based on the findings, the researchers recommended, among others, that the universities should focus on improving the infrastructure, particularly reliable electricity supply and internet connectivity, and increase funding for the development of new smart learning systems, such as virtual reality, gamification, smart classrooms, etc.

Published: February 2025

In this investigation, the academic achievement of government pupils in secondary schools in Ibadan, Oyo State, was compared before and after they were exposed to teacher explanatory techniques and argumentation learning. The study looked at how well male and female government students retained material after using the Teacher Expository approach (TES) and Argumentation Learning Strategy (ALS), as well as how well they performed academically after using the argumentation learning approach. An experimental research design with a non-equivalent pretest-posttest control group was used. All 133 pupils from four senior secondary schools in Ibadan made up the study population, and they were chosen at random. While the control group B received instruction utilizing the teacher explanatory technique, the group performing the experiment A was introduced to the argument learning strategy. The gathered data was examined using the Government Performance Test (GPT). Prior to being exposed to the argumentation learning technique, academic performance did not significantly differ, according to the data. The academic achievement of pupils who received argumentation learning and instructor exposition tactics, however, differed significantly. There was a substantial difference in the retention of government concepts by students who were taught utilizing the argumentation technique. As a result, the study came to the conclusion that students who are exposed to argumentative learning strategies are more likely to remember the material than those who are exposed to explanatory.
Effectiveness of self- efficacy training skills on adolescents’ sexual risk- taking behavior in Oyo state, Nigeria

Particularly in Nigeria, parents, educators, and social workers are becoming increasingly concerned about adolescents' sexually risky behavior. In addition to analyzing the moderating effects of gender and socioeconomic position, this study looked into how self-efficacy training affected teenagers' sexual risk-taking behaviors. With 80 senior secondary school students, ages 14 to 19, from public schools in Oyo State, Nigeria, participating, a pre-test, post-test, randomized quasi-experimental design was used. These students were divided into experimental and control groups at random, and the experimental group was given self-efficacy training for eight weeks. The Adolescent Sexual Behavior Inventory was used to gather data, and Analysis of Covariance (ANCOVA) was used to evaluate the results. The findings showed that therapy, gender, and socioeconomic level had no discernible effects on taking risks with sexual behaviors. Likewise, there were no discernible interaction effects between gender, socioeconomic level, and treatment. The results imply that without addressing more extensive sociocultural factors, self-efficacy training might not be enough to reduce dangerous behaviors. In order to successfully lower teenagers' sexual risk-taking behaviors, the study suggests incorporating digital literacy, parental participation, and comprehensive sex education into intervention programs. To solve these issues, more research is advised to examine comprehensive and situation-specific approaches.

Evaluation of Traditional and Innovative Budget Approaches in Improving Resource Allocation Efficiency
Authors: Sunaryo Dwi , Yanti Nofarina Maulida , Amrulloh Rifqi , Lestari Tina
Published: February 2025

Purpose: This study evaluates the strengths and limitations of traditional and innovative budgeting approaches and their impact on resource allocation efficiency in public and private organizations. The research seeks to identify how hybrid budgeting systems can address the challenges of traditional methods while enhancing flexibility, accountability, and responsiveness in financial management.
Research Design and Methodology: A qualitative systematic literature review (SLR) was conducted to synthesize insights from relevant studies on traditional and innovative budgeting frameworks, including Performance-Based Budgeting (PBB) and Zero-Based Budgeting (ZBB). The research draws from peer-reviewed academic articles, case studies, and financial management reports to comprehensively understand budgeting practices across various organizational contexts.
Findings and Discussion: The findings reveal that traditional budgeting provides stability and control but lacks adaptability in dynamic environments due to its reliance on historical data and fixed expenditure categories. In contrast, innovative approaches such as PBB and ZBB enhance resource allocation efficiency by linking budgets to performance outcomes and encouraging critical evaluation of expenditures. However, these methods face challenges related to technological infrastructure, managerial readiness, and internal resistance. The discussion highlights the potential of hybrid systems that combine traditional approaches' stability with innovative methods' flexibility to create more adaptive financial management systems.
Implications: This study offers valuable insights for policymakers and practitioners by recommending adopting hybrid budgeting approaches supported by cloud-based financial systems and comprehensive training programs. By fostering a culture of accountability and transparency, organizations can enhance resource allocation, improve financial performance, and build resilience to economic and policy changes.
Digital Taxes on Global Tech Companies and Interstate Tensions in the Digital Economy
Authors: Nurwanah Andi
Published: February 2025

Purpose: This study examines the impact of Digital Services Taxes (DSTs) on multinational tech companies and explores the geopolitical tensions arising from fragmented digital tax policies. It aims to assess how DSTs influence corporate strategies and contribute to regulatory and economic challenges in the global digital economy.
Research Design and Methodology: A qualitative systematic literature review (SLR) was employed to analyze secondary data from peer-reviewed articles, policy documents, and international frameworks. The study integrates corporate strategy, international relations, and tax governance perspectives to understand DSTs' complexities comprehensively.
Findings and Discussion: The findings reveal that DSTs significantly affect investment allocation, operational efficiency, and pricing strategies of multinational tech firms. Increased compliance costs and risks of double taxation challenge profitability and global competitiveness. Geopolitical tensions between countries implementing DSTs and those opposing them highlight the need for collaborative international tax reforms. The OECD’s Two-Pillar Plan emerges as a critical framework to address regulatory fragmentation and foster fiscal equity. The discussion underscores the role of stakeholder theory in bridging conflicting interests among governments, corporations, and societies to create sustainable solutions for digital taxation.
Implications: This study highlights the importance of multilateral approaches to digital taxation and collaboration between policymakers and tech companies. Practical implications include developing transparent and inclusive tax frameworks that support innovation and global economic stability. For managers, adopting proactive compliance strategies and engaging in policy reforms are essential to navigate the challenges DSTs pose.
The asymptotic number of simple singular vector tuples of a cubical tensor
Authors:   Department of Mathematics, Dartmouth College, Hanover, New Hampshire USA, Pantone Jay
Published: February 2025

S. Ekhad and D. Zeilberger recently proved that the multivariate generating function for the number of simple singular vector tuples of a generic \(m_1 \times · · · \times m_d\) tensor has an elegant rational form involving elementary symmetric functions, and provided a partial conjecture for the asymptotic behavior of the cubical case \(m_1 = · · · = m_d\). We prove this conjecture and further identify completely the dominant asymptotic term, including the multiplicative constant. Finally, we use the method of differential approximants to conjecture that the subdominant connective constant effect observed by Ekhad and Zeilberger for a particular case in fact occurs more generally
Number of singletons in involutions of large size: a central range and large deviation analysis
Authors:   Département d’Informatique, Université Libre de Bruxelles, CP 212, Boulevard du Triomphe, B-1050, Bruxelles, Belgium, Louchard Guy
Published: February 2025

In this paper, we analyze the asymptotic number \( I(m,n) \) of involutions of large size \( n \) with \( m \) singletons. We consider a central region and a non-central region. In the range \( m = n - n^\alpha \), \( 0 < \alpha < 1 \), we analyze the dependence of \( I(m,n) \) on \( \alpha \). This paper fits within the framework of Analytic Combinatorics.
Diophantine equations for analytic functions
Authors:   Department of Mathematics, Federal University of Paraiba, Brazil &, Faculty of Graduate Studies,, Dalhousie University, Canada., Zadeh Safoura
Published: February 2025

We consider analogs of several classical diophantine equations, such as Fermat’s last theorem and Catalan’s conjecture, for certain classes of analytic functions. We give simple direct proofs avoiding use of deep theorems in complex analysis. As a byproduct of our results, we obtain new proofs for the corresponding results over polynomials.
Edge hub number in graphs

Let \( G \) be a graph, a subset \( S \subseteq E(G) \) is called an edge hub set of \( G \) if every pair of edges \( e, f \in E(G) \setminus S \) are connected by a path where all internal edges are from \( S \). The minimum cardinality of an edge hub set is called the edge hub number of \( G \), and is denoted by \( h_e(G) \). If \( G \) is a disconnected graph, then any edge hub set must contain all of the edges in all but one of the components, as well as an edge hub set in the remaining component. In this paper, the edge hub number for several classes of graphs is computed, and bounds in terms of other graph parameters are also determined.
Log-concavity of two sequences related to Cauchy numbers of two kinds
Authors:   Department of Mathematics, Shanghai University, Shanghai 200444, China., Liu Rui-Li , Zhao Feng-Zhen ,   Department of Mathematics, Shanghai University, Shanghai 200444, China.
Published: February 2025

For Cauchy numbers of the first kind \(\{a_n\}_{n \geq 0}\) and Cauchy numbers of the second kind \(\{b_n\}_{n \geq 0}\), we prove that two sequences \(\left\{ \sqrt[n]{|a_n|} \right\}_{n \geq 2}\) and \(\left\{ \sqrt[n]{b_n} \right\}_{n \geq 1}\) are log-concave. In addition, we show that two sequences \(\left\{ \frac{1}{\sqrt[n]{|a_n|}} \right\}_{n \geq 2}\) and \(\left\{ \frac{1}{\sqrt[n]{b_n}} \right\}_{n \geq 1}\) are log-balanced.
On mutually orthogonal certain graph squares

This paper gives some new results on mutually orthogonal graph squares (MOGS). These generalize mutually orthogonal Latin squares in an interesting way. As such, the topic is quite nice and should have broad appeal. MOGS have strong connections to core fields of finite algebra, cryptography, finite geometry, and design of experiments. We are concerned with the Kronecker product of mutually orthogonal graph squares to get new results of the mutually orthogonal certain graphs squares.
New insight into results of Ostrowksi and Lang on sums of remainders using Farey sequences
Authors:   Universität Magdeburg, IAN, Gebäude 02, Universitätsplatz 2, D-39106 Magdeburg, Germany, Kunik Matthias
Published: February 2025

The sums \( S(x, t) \) of the centered remainders \( kt - \lfloor kt \rfloor - 1/2 \) over \( k \leq x \) and corresponding Dirichlet series were studied by A. Ostrowski, E. Hecke, H. Behnke, and S. Lang for fixed real irrational numbers \( t \). Their work was originally inspired by Weyl's equidistribution results modulo 1 for sequences in number theory.

In a series of former papers, we obtained limit functions which describe scaling properties of the Farey sequence of order \( n \) for \( n \to \infty \) in the vicinity of any fixed fraction \( a/b \) and which are independent of \( a/b \). We extend this theory on the sums \( S(x, t) \) and also obtain a scaling behavior with a new limit function. This method leads to a refinement of results given by Ostrowski and Lang and establishes a new proof for the analytic continuation of related Dirichlet series. We will also present explicit relations to the theory of Farey sequences.

The hub-integrity of a graph is given by the minimum of \( |S| + m(G - S) \), where \( S \) is a hub set and \( m(G - S) \) is the maximum order of the components of \( G - S \). In this paper, the concept of hub edge-integrity is introduced as a new measure of the stability of a graph \( G \), and it is defined as \(HEI(G) = \min\{|S| + m(G - S)\},\) where \( S \) is an edge hub set and \( m(G - S) \) is the order of a maximum component of \( G - S \). Furthermore, an \( HEI \)-set of \( G \) is any set \( S \) for which this minimum is attained. Several properties and bounds on the \( HEI \) are presented, and the relationship between \( HEI \) and other parameters is investigated. The \( HEI \) of some classes of graphs is also computed.

Guibert and Linusson introduced the family of doubly alternating Baxter permutations, i.e., Baxter permutations \( \sigma \in S_n \), such that \( \sigma \) and \( \sigma^{-1} \) are alternating. They proved that the number of such permutations in \( S_{2n} \) and \( S_{2n+1} \) is the Catalan number \( C_n \). In this paper, we compute the expected limit shape of such permutations, following the approach by Miner and Pak.

The growing complexity of maritime operations demands deck officers with advanced competencies and a strong understanding of sustainability principles. This study addresses critical gaps in maritime vocational education by exploring the effectiveness of current training programs, the integration of sustainability, and the role of technology-driven approaches. While previous research has focused on technical skills aligned with STCW standards, limited attention has been paid to leadership, communication, and environmental education. The research sought to answer how maritime training can be enhanced to address these gaps. Using a systematic literature review and qualitative analysis of insights from maritime professionals, educators, and graduates, the study synthesized theoretical frameworks with real-world experiences. Data were collected through semi-structured interviews and questionnaires, analyzed using thematic coding, and triangulated with findings from the literature review. The results demonstrate strong technical training aligned with STCW standards but reveal fragmented sustainability integration and inadequate leadership preparation. Simulation-based training was identified as highly effective, though it requires support from mentorship and real-world experiences. The findings provide actionable recommendations for enhancing curricula, fostering industry-academic partnerships, and refining policies to better prepare deck officers for modern maritime challenges. This research offers a practical roadmap for transforming maritime education, ensuring safety, operational efficiency, and sustainability in global maritime operations.

This research aims to determine the analysis of service quality on customer satisfaction at the Tingkir Type A Terminal, Salatiga City. In this research, the objects taken were service users at the Tingkir Terminal. Data sources include primary and secondary data. The sample in this study was 100 service user respondents at Tingkir Terminal. Data collection was carried out using observation methods, literature studies, interviews, documentation and questionnaires. The data analysis technique is a multiple linear regression technique which is first tested through a questionnaire test (validity and reliability) and classical assumption tests (autocorrelation, heteroscedasticity, multicollinearity, normality). The results of the analysis using the statistical tools of the SPSS V.26 program obtained a multiple linear regression equation: Y = 2,637 + 0,170.X1 + 0,203.X2 + 0,180.X3 + 0,179.X4 + 0,171.X5 + μ. The results of the multiple linear regression equation show that the Tangible Variable (X1) has a tcount of 0.170 and a ttable of 1.66105, so H0 is rejected and Ha is accepted. The Reability variable (X2) has a tcount of 0.203 and a ttable of 1.66105, so H0 is rejected and Ha is accepted. The Responsive Variable (X3) has a tcount of 0.180 and a ttable of 1.66105, so H0 is rejected and Ha is accepted. The variable Emphaty (X4) has a tcount of 0.179 and a ttable of 1.66105, so H0 is rejected and Ha is accepted. The Assurance variable (X5) has a tcount of 0.171 and a ttable of 1.66105, so H0 is rejected and Ha is accepted. Based on the results of the study, conclusions can be drawn from multiple linear regression analysis and the distribution of respondents' answers regarding independent variables (Tangible, Reability, Responsive, Emphaty, Assurance) has an influence on the dependent variable (Customer Satisfaction).

Authors: Batubara Noor Azida , Yuliyana Dewi
Published: February 2025

Di era globalisasi dan modernisasi, krisis identitas agama menjadi tantangan yang dihadapi banyak individu dan komunitas, terutama di tengah arus informasi yang begitu cepat dan beragam. Fenomena ini sering kali memunculkan ekstremisme, eksklusivisme, atau justru sikap acuh tak acuh terhadap nilai-nilai keagamaan. Moderasi beragama hadir sebagai solusi untuk menyeimbangkan pemahaman keagamaan yang inklusif, toleran, dan menghargai keberagaman, tanpa menghilangkan esensi ajaran agama itu sendiri.
Artikel ini bertujuan untuk menganalisis pentingnya moderasi beragama dalam menghadapi tantangan krisis identitas agama, serta implikasinya terhadap penguatan hubungan antar kelompok agama di Indonesia. Penelitian ini menggunakan metode kualitatif dengan pendekatan deskriptif-analitis untuk mengeksplorasi moderasi beragama sebagai solusi dalam menghadapi krisis identitas agama. Teknik pengumpulan data dalam penelitian ini dilakukan melalui studi literatur dan wawancara. Teknik analisis data dalam penelitian ini menggunakan metode deskriptif-analitis, di mana data yang diperoleh melalui studi literatur dan wawancara dianalisis secara kualitatif.  Hasil penelitian menunjukkan bahwa moderasi beragama berperan penting dalam mengatasi krisis identitas agama dengan menanamkan pemahaman keagamaan yang inklusif, toleran, dan kontekstual. Krisis identitas agama sering kali dipicu oleh pemahaman yang ekstrem, baik dalam bentuk radikalisme maupun sekularisme yang berlebihan. Implikasi hasil penelitian ini menunjukkan bahwa moderasi beragama dapat dijadikan strategi efektif dalam menangani krisis identitas agama, baik dalam lingkup individu maupun sosial. Temuan ini menggarisbawahi pentingnya peran lembaga pendidikan, tokoh agama, dan kebijakan pemerintah dalam mengintegrasikan nilai-nilai moderasi dalam sistem pendidikan, dakwah, serta regulasi sosial. Selain itu, pemahaman yang lebih inklusif terhadap agama dapat memperkuat kohesi sosial dan mencegah konflik berbasis perbedaan keyakinan.

Pendidikan Pancasila dan Kewarganegaraan (PPKn) memiliki peran yang penting dalam membentuk aspek kognitif dan afektif peserta didik di sekolah dasar. Namun, tantangan dalam pembelajaran PPKn seringkali muncul karena kurangnya penggunaan metode pembelajaran yang interaktif, sehingga pesera didik cenderung pasif dan kurang termotivasi dalam belajar. Kondisi ini berdampak pada rendahnya hasil belajar peserta didik dan lemahnya pengembangan sikap kerja sama peserta didik. Untuk memahami lebih mendalam terkait penelitian dalam peningkatan hasil belajar dan sikap kerja sama peserta didik pada mata pelajaran PPKn, sebuah kajian pustaka dibutuhkan. Penelitian ini bertujuan untuk mendeskripsikan implementasi model pembelajaran Think Pair Share (TPS) dalam meningkatkan hasil belajar dan sikap kerja sama pada mata pelajaran PPKn di sekolah dasar. Metode yang digunakan dalam penelitian ini adalah Systematic Literature Review (SLR) dengan model Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Data dikumpulkan melalui pencarian literatur dengan kriteria inklusi yang telah ditentukan pada database Google Scholar. Hasil kajian menunjukkan bahwa model pembelajaran TPS secara signifikan meningkatkan hasil belajar peserta didik dan sikap kerja sama. Dalam banyak penelitian, peserta didik menunjukkan peningkatan partisipasi aktif, keterampilan bekerja sama, dan pemahaman materi PPKn setelah diterapkannya TPS. Selain itu, peserta didik juga mampu berkomunikasi lebih baik dan menghargai pendapat teman-teman mereka selama proses pembelajaran melalui aktivitas diskusi berpasangan dan kelompok kecil. Kesimpulan dari kajian ini adalah model pembelajaran tipe Think Pair Share terbukti efektif dalam meningkatkan hasil belajar dan sikap kerja sama siswa. Sehingga model ini direkomendasikan sebagai metode pembelajaran kooperatif yang inovatif dan dapat diterapkan pada berbagai jenjang pendidikan, terutama pada mata pelajaran yang memerlukan interaksi sosial.

The funded pension system is characterized by an optimal investment policy, which should achieve adequate profitability with minimal risks. In this regard, different countries implement different approaches to managing pension assets. After the transition from a distributive pension system to a funded one in 2014, the Government of Armenia faced the same task. As part of the study, we compared the models of Armenia and the Dominican Republic. The latter, in turn, is notable for its high return on investment. Despite the fact that Armenian pension funds do not yet have the same profitability indicator due to the short period of operation of the new pension system, the policies of both countries are very similar in terms of investing in the national economy. This paper analyzes the approaches of the two countries and identifies the main risks and advantages of such models.

The primary role of border security personnel is to safeguard borders against illegal trans-border activities during peacetime and provide military support during wartime. Medical facilities are available to residents, offering direct oral care for minor procedures, with comprehensive dental treatments managed through empanelled clinics under a government insurance system. This study aimed to evaluate the oral health status, treatment needs, and prevalence of oral pre-malignant conditions among security forces personnel and their families at training centres in Delhi NCR. A multi-centric crosssectional study was conducted at three training centres. Permission was obtained from BSF headquarters for the oral health screening program. Oral health education topics included oral cancer screening, early detection, oral diseases, their prevention, and tobacco cessation. Brief explanations of dental procedures, such as pit and fissure sealants, dental caries restoration, and root canal treatments, were provided. Demonstrations of proper brushing techniques and oral hygiene maintenance measures were conducted. Participants were encouraged to discuss experiences and challenges, which were addressed by attending clinicians. Following the sessions, oral screenings identified oral diseases and premalignant lesions. Affected participants were informed about their condition and referred for treatment. Those using tobacco were counselled, provided with educational materials, and motivated to quit. The study concluded that the oral health status of BSF personnel was comparable to the general population, possibly due to the rigorous physical and medical fitness criteria required during recruitment.
