Published: July 2024

The viaduct is an important infrastructure for urban sustainable development, but it will inevitably pass through a coal mining subsidence area in coal resource-based cities, which poses a threat to the construction and operation of the viaduct. However, there is a lack of research on long time-series monitoring and assessing the safety of elevated bridges above subsidence areas, both domestically and internationally. In this study, a resource-based city viaduct in Shandong, China, was selected as the research object, utilizing SBAS-InSAR technology for deformation monitoring during bridge construction and post-opening phases. The viaduct based on the goaf was analyzed by the key settlement subsection. Before completing construction (March 2019 to December 2020), research revealed that the cumulative maximum deformation in the bridge area was 44mm and the maximum uplift was 22 mm, with overall stability in the underlying subsidence area. After completion (January 2021 to July 2023), the cumulative maximum deformation value in the elevated bridge area was 10mm and the maximum uplift was 6 mm, indicating minimal fluctuations over three years, maintaining overall stability. This stable condition ensures the safety of construction and operation of regional elevated bridges. These findings not only support the safe operation of bridges in underlying subsidence areas but also provide a new approach to sustainable areas globally, especially in coal resource-based urban areas.

While SARS-CoV-2 has transitioned to an endemic phase, infections caused by newly emerged variants continue to result in severe, and sometimes fatal, outcomes or lead to long-term COVID-19 symptoms. Vulnerable populations, such as PLWH, face an elevated risk of severe illness. Emerging variants of SARS-CoV-2, including numerous Omicron subvariants, are increasingly associated with breakthrough infections. Adapting mRNA vaccines to these new variants may offer improved protection against Omicron for vulnerable individuals. In this study, we examined humoral and cellular immune responses before and after administering adapted booster vaccinations to PLWH, alongside a control group of healthy individuals. Four weeks following booster vaccination, both groups exhibited a significant increase in neutralizing antibodies and cellular immune responses. Notably, there was no significant difference in humoral immune response between PLWH and the healthy controls. Immune responses declined rapidly in both groups three months post vaccination. However, PLWH still showed significantly increased neutralizing antibody titers even after three months. These findings demonstrate the efficacy of the adapted vaccination regimen. The results suggest that regular booster immunizations may be necessary to sustain protective immunity.
The Influence of Brand Greenwashing on EV Purchase Intention: The Moderating Role of Consumer Innovativeness and Peer Brand Attitude
Authors: Liao Yuting , Wu Liang
Published: July 2024

In the context of new energy Electric Vehicles (EVs), certain car manufacturers engage in deceptive behaviors known as “greenwashing”, including activities such as “subsidy cheating”, “exaggerating carbon reduction claims”, and “selective disclosure of environmental information”. These behaviors have a negative impact on industry progress. While previous studies suggest that consumers’ perceptions of greenwashing towards individual brands extend to the industry as a whole and influence their overall purchase intentions, there remains a gap in understanding how these behaviors specifically affect consumers’ willingness to purchase EVs. To address this gap and enrich the literature on the relationship between greenwashing and consumer choice, this study uses ABC attitude theory and experimental methods to investigate the impact of greenwashing in the EV sector on consumers’ vehicle preferences in three experiments. The results show that consumers’ perceptions of greenwashing in one EV brand negatively influence their purchase intentions towards other brands, mediated by a general skepticism towards environmental claims in the industry. In addition, consumers’ innovativeness and attitudes towards other brands play a negative moderating role in this relationship. The research findings provide comprehensive insights into the complex impact of brand greenwashing on consumer behavior within the EV industry.

Can PPP Contracts Improve the Performance of the National Road Sector?
Authors: Utarja Josep Bely
Published: July 2024

This article attempts to answer two questions. The first is whether Public-Private Partnership (PPP) contracts can be easily implemented for national road preservation projects. The second is how the PPP contracts can increase the value for money (VfM) of the national road preservation budget. The institutional environment of national road sector is discussed first in order to highlight the particular role of road preservation contracts between the Government and the business sectors in that environment. Then, the discussion continued with types of contracts that have been used in this sector, historically. At the time of this writing, PPP contract has not been used in this sector. To approach this matter the next discussion is about PPP and VfM definition in the current regulation as well as their features in literature. Based on this discussion, characteristics comparison of the available types of contract is developed, including how these types of contracts, especially KPBU contracts, can be used to achieve VfM. The following section presents a simple simulation method to assess VfM achievement based on comparison of present value cost of public service comparator and PPP. The simulation is used to understand how the variables that determine VfM interact with each other in determining the final result. Finally, the last section contains the conclusions on how PPP contracts can increase the VfM of national road preservation project. Value for Money can be achieved using PPP contract if risks transferred from the Government to business / private entity is significant enough so that the combination of both incentives and the entity’s capability can reduce the total cost of risks more than to compensate the difference between the entity’s cost of capital and the Government cost of capital. In this case, the scale of the project is also important, given the complexity of PPP contract resulted in relatively higher transaction costs compare to other types of contracts. This article does not discuss the design of performance-based incentive-oriented contract for national road preservation projects. In addition, the risks analysis done in the numerical simulation is simplified and, thus, requires further data collection for more detailed application. The externalities come from the construction phase to the operational and maintenance phase have not yet based on empirical evidence in this sector. This article also does not address issues on how to create level of competition in the procurement stage as well as in the operational stage that can promote value for money. Lastly, the risks discussed in the types of contracts only limited to supply risks. The use of PPP contracts to replace conventional procurement contracts will not automatically reduce primary balance deficit. Assessments and steps to ensure the achievement of value for money from the PPP contract must be done and planned in advance. This is the first article discussing value for money from PPP contract for Indonesian national road preservation projects.

Published: July 2024

Infrastruktur sosial sebagai bagian dari pembangunan fisik itu sendiri harus memberikan pelayanan sosial seperti sekolah, universitas, rumah sakit, penjara dan perumahan rakyat. Pelayanan ini juga tidak terbatas pada bentuk-bentuk tersebut, namun juga melingkupi infrastruktur sosial yang berdimensi fisik seperti fasilitas kesehatan, fasilitas rekreasi, keamanan dan pemadam kebakaran, pusat seni dan budaya dan fasilitas publik lainnya. Penelitian ini memfokuskan studi pada infrastruktur sosial yakni Anjungan Cerdas (Roadside Station) yang diadopsi dari Michinoeki Jepang. Hal ini dipandang tepat karena anjungan cerdas memberikan sejumlah fungsi sosial yang diamanatkan ke dalam infrastruktur fisik yang dibangun oleh pemerintah, dalam hal ini oleh Kementerian PUPR yang berlokasi di 2 lokasi yaitu Kabupaten Trenggalek dan Kabupaten Jembrana. Pengembangan skema pengelolaan anjungan cerdas dimaksudkan agar kesinambungan dalam fungsinya sebagai infrastruktur sosial memenuhi kebutuhan publik. Selanjutnya hal ini perlu mendapat perhatian khusus, karena pengelolaan infrastruktur yang selama ini senantiasa menggunakan anggaran pemerintah sering kali tidak optimal dalam memberikan pelayanan publik. Di sisi lain, pengembangan skema pembiayaan dengan melibatkan Badan Usaha merupakan salah satu solusi untuk pengelolaan infrastruktur yang lebih baik. Dalam penelitian ini, isu utama yang akan diangkat adalah skenario pembiayaan apa saja yang dapat dikembangkan untuk pengelolaan infrastruktur anjungan cerdas. Dari skema pengelolaan yang dihasilkan, ditetapkan bahwa pengelolaan anjungan cerdas dapat menggunakan skema pemanfaatan Barang Milik Negara (BMN), Badan Layanan Umum (BLU), dan Kerjasama Pemerintah dengan Badan Usaha (KPBU).
Reforming Public-Private Partnerships in Railway Services: Learning from the Jakarta Monorail Project Debacle
Authors: Arafia Diantha
Published: July 2024

Public-Private Partnerships (PPPs) offer a promising strategy for accelerating railway infrastructure development, yet they entail significant risks if not executed correctly. Indonesia has adopted PPPs since the 1990s, but their impact on railway services remains underexplored. This paper suggests improvements to Indonesia’s railway PPP mechanism to improve effectiveness, efficiency, and service deliverability. It argues that the effectiveness of railway PPPs is hindered by the public sector’s limited capacity and weak regulatory and institutional frameworks. The research employs a case study of the Jakarta Monorail project, terminated in 2015 after 11 years of problematic development. The research methods include literature reviews and a comparative analysis of the case with two prominent railway PPPs in other developing countries: the Bangkok Transit System in Thailand and the Delhi Mass Rapid Transit System Phase I in India. The findings lead to two key recommendations for the government: reorganizing the roles and coordination processes of key PPP agencies and establishing a continuous capacity-building scheme for PPP stakeholders. These recommendations may create a more supportive environment for PPPs, thereby increasing the likelihood of successful railway PPP implementation in Indonesia.

Authors: Mohd Azmi Siti Izamaiera , Mohd Saman Alias , Ramly Ramzyzan
Published: July 2024

The injection molding process involves heating a thermoplastic polymer above its melting point and injecting it into a mold. The polymer then cools and solidifies to form the final part. The process consists of four stages: clamping, injection, cooling, and ejection. Among these stages, cooling plays a crucial role as it requires an efficient cooling system to transfer heat from the mold at a consistent rate, ensuring high-quality final products. This project specifically focuses on investigating the impact of different cooling media used in the cooling system for the mold. The aim is to compare the effectiveness of various cooling media on the cooling performance of the injection-molded product. Different types of coolants, including water, oil, or other solution mixtures, have been considered for their ability to reduce or regulate the temperature of the system. CAD modeling was prepared for the case study, along with a pre-designed conformal cooling channel and gating system. After conducting the simulation analysis, water emerged as the most effective coolant, demonstrating superior results compared to other coolant options. The results also highlight the feasibility of using alternative coolants that offer comparable cooling performance.

Authors: Abdul Rashid Nur Firdaus , Mohd Sabri Nurin Qistina
Published: July 2024

Heavy metals from human activities, such as industrial emissions and mining waste, contribute to environmental, nutritional, and health issues. Catharanthus roseus, a phytoremediation plant, was tested to determine the levels of heavy metals in soil and plants. The experiment involved preparing various amounts of heavy metals by combining four elements: Cadmium (Cd), Copper (Cu), Lead (Pb), and Zinc (Zn). Four treatment groups were tested, each with varying levels of heavy metal contamination. The initial group (T0) served as the positive control, while the next four groups (T1-T4) were subjected to escalating levels of heavy metals. T1 was given a 200ml solution containing 0.9 (Cd) + 4.0 (Cu) + 0.18 (Pb) + 6.9 (Zn). T2 was given a 200ml solution containing 11.90 (Cd) +19.80 (Cu) +36.00 (Pb) + 54.3 (Zn). T3 was given a 200ml solution containing 23.80 (Cd) + 39.60 (Cu) + 72.00 (Pb) + 108.6 (Zn). T4 was given a 200ml solution containing of 23.80 (Cd) + 39.60 (Cu) + 72.00 (Pb) + 108.6 (Zn). The dataset included measurements of soil pH, heavy metal concentrations, plant height, and shoot and root length. The results showed that the T3 solution, consisting of 23.80 (Cd) + 39.60 (Cu) + 72.00 (Pb) + 108.6 (Zn), had the most favourable plant growth performance based on soil and plant concentrations. This suggests that immediate action is needed to ensure safe food availability.

Published: July 2024

Zinc oxide (ZnO) nanostructures have gained popularity in sensor technology due to their unique properties and facile device integration. However, the intrinsic optical and electrical properties of ZnO are suboptimal for direct industrial applications, necessitating enhancements through doping. This study investigates the impact of niobium (Nb) doping concentrations on the physical, optical, and electrical characteristics of ZnO nanostructures. FESEM analyses indicate successful deposition of ZnO on silicon nanoparticles substrates, with nanostructure sizes peaking at 88 nm and 115 nm for 6% and 8% Nb dopant concentrations, respectively. XRD results suggest that the structural integrity of the nanostructures is maintained up to a 10% doping level, with an optimal concentration at 6%. UV-Vis spectroscopy shows a shift in the absorption peak into the visible range and a decrease in maximum reflectivity from 47.5990% at 2% doping to 40.9205% at 6% doping, indicating enhanced light absorption suitable for optoelectronic applications. Electrical measurements reveal that a 6% Nb dopant concentration yields the lowest resistivity and highest conductivity among the tested samples. These findings underscore the potential of Nb-doped ZnO nanostructures in improving the performance of optoelectronic devices through tailored doping strategies.

Authors: Ismail Norliana , Zakaria Siti Radiaton Adawiyah , Samsudin Salfarina
Published: July 2024

The issue of land subdivision conflicts, specifically "lot lidi," remains unresolved. To date, the rights of “lot lidi” purchasers are not safeguarded under the National Land Code (NLC) due to the failure to register buyers' names in the documents of title. This study aims to devise a method for registering buyers' names in the documents of title from a land law perspective. The objective is to identify existing land laws that can address the proprietorhip issues of “lot lidi”. The scope of this study focuses on resolving “lot lidi” issues through current land laws that can be implemented by the Land Office and State Authorities. Additionally, the study specifically addresses “lot lidi”, which are alienated lands categorized as agricultural and illegally subdivided through unapproved sketches for residential plots. The research also examines the sale of “lot lidi” outside the framework of NLC, which prevents the registration of buyers' names in the documents of title due to legal prohibitions on such transactions. This qualitative study employs literature review and semi-structured interviews with respondents from land administration, legal officers, legal practitioners, and academics. The findings reveal ten (10) provisions within the NLC that can be referenced to develop a method for resolving “lot lidi” proprietorship. The study's results yield two (2) main outcomes: first, a detailed breakdown of provisions based on three (3) stages—application, approval, and registration; second, specific attributes within each stage that are organized to be easily understood. Ultimately, the existing provisions for resolving “lot lidi’ and their details can be extracted to guide stakeholders in developing solutions for “lot lidi” proprietorhip issues.

Published: July 2024

A diverse array of religious practices was introduced to the community, giving rise to a multitude of Islamic spiritual practices and mysticism, including sufism and order-related branches referred to as tariqa. This subject generates confusion among members of the community concerning the authenticity of the teachings. The aim of this research is to analyse the constituent elements that comprise the tenets of sufism and tariqa in order to clarify the societal implications of these observances. The qualitative methodology utilised in this study consists of focus group discussions. The participants were selected through a process involving esteemed committees of scholars from diverse fields within Islamic Studies. The primary method of data acquisition utilised in this study was semi-structured interviews. The panellists were given the opportunity to respond to any inquiries that arose in relation to this research. The results indicate that the presence of various religious orders, or Tariqa, in Malaysia is a substantial contributor to community confusion concerning sufism and tariqa as a whole. Sufism and Tariqa are similarly established to ensure that their respective structures are passed down from generation to generation, thus protecting their respective functions. Tariqa and sufism agendas continue to be permitted under specific recent policies. However, this study suggests that both governmental and non-governmental organisations ought to develop an awareness campaign concerning the concept of Sharia-compliant spiritual practices. Sharia compliance refers to the observance of Islamic regulations and laws.

Qiyas plays a crucial role in the formulation of Sharia law, being one of the primary sources of evidence used in the science of usul al-fiqh. Although usul al-fiqh, the science that discusses the process of deriving legal rulings, is a necessity for those involved in the issuance of legal rulings, it is observed that in the current context, the literature on usul al-fiqh has not received adequate attention, especially in the domain of Islamic finance. Therefore, one of the suitable sources of usul al-fiqh for resolving modern issues that were not addressed in ancient times is the source of qiyas. Qiyas is essential in determining the element of similarity from the perspective of the ‘illah (effective cause) of the law between an issue explicitly mentioned in the Sharia texts and a new issue. Furthermore, this source is accepted as evidence by the reputable scholars among the four Sunni schools of thought. This study aims to analyze the application of qiyas as evidence in contemporary Islamic financial practices. The study employs a qualitative approach, involving a literature review encompassing books, journals, and relevant circulars. The collected materials are analyzed using document analysis methods. The findings of the study indicate that several practices in Islamic finance are implemented based on the justification of qiyas. These practices include issues related to fiat currency, the requirement for a minimum amount of physical assets in sukuk, the zakat on jewelry (gold and silver), and the zakat on publicly listed company shares. Therefore, it can be concluded that qiyas plays an important role as a primary reference for contemporary issues in Islamic finance. It is recommended that current Islamic finance industry practitioners thoroughly understand the source of qiyas.

Second language (L2) postgraduate students are susceptible to experience second language writing anxiety (SLWA) in dissertation writing as they tend to find the writing process arduous. SLWA relates to the recurring negative and anxious feeling when students write which could influence their cognition, behaviour, and physical condition. This reflects the interrelationship between individual’s affect and cognitive process and the negative correlation between SLWA and writing performance reported in past studies. However, more evidence is needed to establish SLWA as an independent construct that could directly affect writing performance. Therefore, this study aimed to explore how SLWA influences L2 postgraduate students’ dissertation writing to have a clearer insight into the phenomenon. This investigation utilised a multiple-case study approach involving four local postgraduate students. Data was obtained through in-depth interviews, audio journals, and personal document analysis. The thematic analysis revealed the following themes: SLWA i) influences emotional states; ii) triggers emotion regulation; and iii) initiates and sustains a debilitative or facilitative psychological loop that influences students’ progress in dissertation writing. Thus, the study posits SLWA as a construct that can directly debilitate writing performance and L2 dissertation writing as having affective costs that makes emotion regulation an important mechanism to restore student’s psychological balance. To overcome SLWA’s influences on dissertation writing, it is recommended that supervisors and language teachers discourage perception of writing inability, recognize writing improvement, identify writing competence, suggest specific solutions to resolve writing issues, and avoid manipulating anxiety to provoke writing performance.

Background: The childhood obesity has led to a decrease in physical activity, which may have detrimental effects on overall well-being, including impairment in musculoskeletal flexibility. Joint flexibility, often known as range of motion, is and a component of muscular fitness that essential for performing daily tasks. Considering the major physiological changes that occurs during adolescence have substantial impact on long-term health, this study aimed to investigate the relationship between body mass index (BMI) and the flexibility of the trunk and hamstring muscles among school adolescents. Methods: A total of 143 school adolescents were recruited using a convenience sampling method. The participants’ body composition was measured using the BMI, while the flexibility of the trunk and hamstring muscles was evaluated using the fingertip-to-floor test and the sit-and-reach test, respectively. The Spearman’s correlation coefficient was utilised to examine the relationship between BMI and muscle flexibility. Results: Most of the participants (n = 64, 44.8%) were underweight, with a mean BMI of 20.2 ± 5.2 kg/m2. There were no significant correlations between BMI and muscle flexibility (trunk, p = 0.965; hamstring, p = 0.829). Additionally, there were significant differences between males and females in trunk flexibility (p = 0.04), but not in hamstring flexibility (p = 0.135). Conclusion: There was no association between BMI and muscle flexibility in this study However, male students demonstrate significantly greater trunk flexibility compared to their female peers.
