Authors: Purwanto Edi , Irawan Agustinus Purna 
Published: April 2024

Abstract
This paper aims to comprehensively investigate the multifaceted factors influencing consumers’ willingness to purchase electric vehicles (EVs), providing a deeper understanding of the drivers behind EV adoption. The study draws on various scholarly sources to examine the intricate relationships among multiple determinants, including environmental concern, performance expectations, effort expectancy, charging point networks, charging time, price, operational costs, incentives, and attitude toward EVs. These factors are analyzed within a conceptual framework, highlighting the pivotal role of attitude as a mediating variable. The review reveals that environmental concern, driven by awareness of the ecological impact of conventional vehicles, motivates individuals to opt for EVs as a more sustainable mode of transportation. Performance expectations, such as energy efficiency and emission reduction, significantly influence consumer preferences. Effort expectancy, indicating the ease of using EV technology, plays a critical role in adoption decisions. Charging infrastructure, both availability and accessibility, is a crucial facilitator of EV adoption, emphasizing the importance of robust charging networks. Concerns about charging time underscore the need for faster and more convenient recharging methods. Price remains a barrier, with high initial costs, although operational cost advantages make EVs economically appealing. Depending on the region, government incentives have varying effectiveness in reducing financial barriers to EV adoption. Attitude toward EVs, acting as a mediating variable, highlights the importance of positive perceptions in shaping consumer intentions. This study offers a comprehensive review of the interplay of factors influencing EV adoption, providing a holistic view of consumer decision-making in the EV market. It emphasizes the need for further empirical research to validate and extend the proposed model. It offers valuable insights for policymakers, manufacturers, and researchers in promoting sustainable transportation solutions and accelerating EV adoption in response to environmental concerns.

Abstract
The Victory International Futures office is running on foreign exchange. It is located in East Java, Indonesia, in Malang. The furniture in this office has an HPL finish, which is typically dark and has a brown cotton color. The light source’s reflections will be lessened as a result. The southeast-facing Victory International Futures building has good lighting. However, the lighting may be improved due to the limited artificial lighting offered in some areas and the absence of windows, which prevents daytime sunshine from reaching its full potential. Using windows where none are present results in an improper exchange of air coming in and going out. This study intends to ascertain the effects on workers caused by the influence of office air circulation and light intensity. This study’s technique, a case study, requires that we visit the office right away. Data gathering methods included surveys, interviews, and using the Light Metre program to gauge light intensity. According to the test results, the typical room has more light than it needs at night. Through smart lighting, this research proposes designs to enhance the quality of conference room interiors, particularly lighting design. A standard light distribution of 73,9 lux is achieved by simulating one type of lamp already present in the space using the Light Metre application.

Authors: Mulyodarsono Natalia Devi Ayu Restuti , Kristopo Hari 
Published: April 2024

Abstract
The safety of street food vendors in Southeast Asian countries is of concern as many do not follow basic food safety principles. The water used to wash cutlery that is not hygienic may cause foodborne illnesses. Therefore, the general aim of this study was to summarize the water hygiene of street vendors in Southeast Asia. PRISMA guidelines were used to find suitable sources for this systematic review. Relevant studies are retrieved from several databases, such as Science Direct, PubMed, SAGE, EBSCOhost, Taylor and Francis, and Scopus. The keywords used to identify the relevant studies were water, water quality, hygiene, sanitation, street vendor, and food safety. The initial search in the databases yielded 80 articles. After the screening process based on the criteria of the article, only 9 articles were used in the final systematic review. The results showed that the water hygiene system in street vendors in Southeast Asia is still relatively unhygienic because most still use bucket water (non-tap water), which can contaminate food and lead to foodborne illness.

Published: April 2024

Abstract
Polyaniline graphite composites have been synthesized using chemical oxidative polymerization method. The graphite powder has been reused which is obtained by used batteries. XRD patterns of graphite show (002) peak and no impurity peaks. Different wt. % (5, 10, 15, 20) of graphite is used for synthesis of composites and studied their electrical conductivity. XRD patterns of composites show increasing intensity with an increasing graphite content. SEM images show plate-like morphology of graphite whereas granular-morphology for PANI. Composite samples show both plate-like morphology and granular morphology indicating that graphite is embedded in the polymer matrix. Electrical characteristics of composite samples have shown a systematic increase in conductivity with an increase in the graphite concentration. Conductive fillers within the polymer matrix can increase the overall conductivity. Higher filler content provides more conductive pathways for electrons, resulting in enhanced conductivity. The detailed studies of these results are discussed and presented in this paper.

Published: April 2024

Abstract
Conductive polymer nanocomposites, which combine the flexibility and conductivity of polymers with the unique properties of nanofillers, have generated interest in various fields such as energy storage, sensors, coatings, and corrosion protection. This study discusses the effect of Yttria-stabilized zirconium nanoparticles (YSZ NPs) on the morphology and electrical conductivity of poly(3,4-ethylenedioxythiophene): poly(4-styrenesulfonate) (PEDOT: PSS). Thin films of PEDOT: PSS and PEDOT: PSS: YSZ were fabricated using spin coating technique. FTIR and XRD characterizations confirmed the interaction between YSZ nanoparticles and the PEDOT: PSS matrix, leading to changes in chemical morphology and film crystallinity. The investigation of the current-voltage (I-V) relationship showed improved electrical conductivity in PEDOT: PSS films with the addition of YSZ nanoparticles, with respective conductivities of 0.028×10−6 S cm−1 and 0.0885×10−4 S cm−1 for pristine and YSZ-containing films. Additionally, the sensing properties of the PEDOT: PSS: YSZ film in detecting organic vapours were studied. These findings suggest that these conducting polymer nanocomposite thin films could potentially be used as electrolyte components in battery cells, supercapacitors, and fuel cells, as well as serve as sensors for certain organic vapours.

Published: April 2024

Abstract
The novel glasses were created using the melt quenching technique and the glass composition xTiO2-(50-x) CaO-50B2O3, where x=0, 1, 3, 5, 7, 9 in mol%, which was characterized by XRD spectra and confirmed the glass samples’ amorphous nature. Using the Archimedes principle, the density of the glasses was determined, and the associated molar volume was estimated. Density increases with increasing mol% TiO2, whereas molar volume decreases, as anticipated. The absorption spectra from the wavelength region of 200nm–1100nm were obtained using a UV-visible spectrometer. Tauc’s plot was used to evaluate the direct and indirect energy band gap, and the fluctuation of the energy band gap with mol% TiO2 has been discussed. The refractive index has also been estimated using energy band gap data. In the 400-4000 cm-1 range, the FT-IR functional groups were confirmed.

Authors: Mohammed Salman K , Zikriya Mohamed , Renuka C. G. 
Published: April 2024

Abstract
Zinc oxide (ZnO) thin films with magnesium (Mg) doping have demonstrated significant potential due to their wide band gap, which enables efficient absorption of ultraviolet (UV) radiation while maintaining transparency to visible light. Sol-gel spin coating methods were used to deposit Mg-doped ZnO thin films. The solution was made with methanol as the solvent, and the starting materials were magnesium acetate tetrahydrate and zinc acetate dihydrate. The integration of Mg content in deposited ZnO films was investigated for structural, morphological, and optical properties using an X-ray diffractometer (XRD), scanning electron microscope (SEM), energy dispersive X-ray analysis (EDAX), and UV-VIS spectrophotometer. Mg-doped ZnO films were produced on quartz substrates and post-annealed at 400°C. According to absorption coefficient calculations, the optical band gap of Mg-doped ZnO films is in the range of 5.4 eV which is ideal for a variety of applications in the field of optoelectronic devices.

Published: April 2024

Abstract
In this work, we describe the preparation of the TiO2 (P25) / Graphitic Carbon Nitride composite and the degradation of pollutants using this composite with persulphate activation. The materials are characterized by XRD, FTIR analysis, etc. XRD analysis confirms the presence of TiO2 anatase and GCN and the characteristic functional groups of both TiO2 and GCN are determined with the help of FTIR. The degradation of crystal violet and Rhodamine B in binary mixtures over this synthesized catalyst is easier than individual catalysts separately. The degradation efficiency of crystal violet over TiO2/GCN composite is 1.5 times higher than GCN and 3 times higher than TiO2 alone and the degradation efficiency of Rhodamine B over TiO2/GCN composite is 1.1 times higher than GCN and 2.4 times higher than TiO2 alone. In flat band analysis, a Z-Scheme catalyst is formed between TiO2 and GCN. The electron transfer between the bands of TiO2 and GCN occurs because of proper band alignment between these materials.

Published: April 2024

Abstract
Crystal structure, magnetic, and electrical resistivity behaviour of Co2FeGe Heusler alloy films deposited at different sputtering parameters have been studied using X-ray diffraction, VSM, and standard four-probe techniques. Though the expected structure was L21, X-ray diffraction studies indicate the A
2-type disordered structure. All films exhibited soft ferromagnetic characteristics having a coercive field of 5-65 Oe and a high ferromagnetic ordering temperature (More than 700 K). The electrical resistivity of the films deposited on the Si substrates was influenced by the substrate temperatures. Out of the different scattering mechanisms present in the low and high-temperature regimes, the two-magnon scattering effect is dominant in all the films. The scattering mechanisms are the same in all films irrespective of the substrate temperature. The optimum sputter deposition parameters that yields good quality Co2FeGe Heusler alloy thin films were found to be 50 W power, 5 mTorr pressure, and 400 °C substrate temperature.

Published: April 2024

Abstract
This study investigates the performance of two types of multi-encapsulated electrode (MEE) plasma actuators, compared to typical dielectric barrier discharge (DBD) plasma actuators, in quiescent air. The objective is to determine whether the multiple encapsulated structure can enhance the performance of the plasma actuator. In the present paper, flow characteristics are investigated by using particle image velocimetry (PIV) and Schlieren visualisation. In addition, the distribution of body force over the gas volume based on the Navier–Stokes equations is calculated from velocity measurements. The obtained results demonstrate that the starting vortex behavior is influenced by electrode arrangement. Specifically, it can be observed that when the first encapsulated electrode is positioned closer to the exposed electrode, then a significantly higher induced velocity can be obtained compared to the baseline condition. In fact, the induced velocity can be increased by up to 1.5 times under this optimize configuration. These results highlight the importance of electrode arrangement in the plasma actuator design. Based on body force estimation, MEE plasma actuators exhibit a significantly higher momentum transfer, particularly in the wall normal direction. The investigation on the mechanical efficiency also reveals that the optimized configuration proposed in the present study can significantly enhance the efficiency. In fact, a four-fold increase in maximum efficiency compared to the typical configuration is observed. These results suggest that the proposed configuration could be considered a promising solution for improving the mechanical efficiency of plasma actuators.

Abstract
The human gastrointestinal tract is colonised by a multifaceted and dynamic population of microorganisms consisting of trillions of microbes called the gut microbiota. Through extensive research using animal models and human studies, the significant contributions of gut microbiota to immune and metabolic balance, protection against pathogens, and even neurobehavioural traits have been established. Members of the genus Bifidobacterium are the first bacteria to colonise the intestinal tract in infants, and now it has been proven that they play a positive role in enhancing the host immunity, nutrient absorption, reducing and treating gastrointestinal infections, as well as improving conditions such as diarrhea, constipation, and eczema. Bacterial nanotechnology is a rapidly growing research area with great potential for improvement and the discovery of innovations in new applications of bacteria such as Bifidobacterium. In this review, we provide an up-to-date summary of the relations of nanotechnology with Bifidobacterium in various fields, including bacterial synthesis of nanoparticles, encapsulation of bacteria, bacterial toxicity of nanomaterial, application in the field of cancer targeting, and also the treatment of other diseases such as Alzheimer’s and IBD.
The influences of Ag nanoparticles on voids growth and solderability about Sn3.0Ag0.5Cu/Cu solder joint

Published: April 2024

Abstract
Although Sn3.0Ag0.5Cu solder (SAC305) has higher reliability, there are a large number of harmful voids in solder joints. Larger voids can reduce thermal conductivity of solder joints. However, as a microstructure growth inhibitor, the influences of Ag nanoparticles on voids growth are not clear at present. Herein, we prove that Ag nanoparticles can increase SAC305 solderability, but promote voids growth. Ag nanoparticles and SAC305 solder paste were mixed by mechanical stirring for 0.5 h. Next, SAC305-xAgP (x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5 wt%) was obtained. The results indicated that solder solderability was improved increasingly with Ag nanoparticles addition. The lower the amount of nanoparticles added, the greater the final loss. After being aged at 100 °C for 150 h, the voids stopped growing. Due to the violent reaction between Ag nanoparticles and flux, the final voids growth rate became faster, and the average voids size changed from 14.34% to 24.91%.
Behaviour of sewage sludge based lightweight aggregate in geopolymer concrete

Published: April 2024

Abstract
The global challenge of sewage sludge disposal has encouraged innovative solutions aimed at reducing environmental impact while simultaneously addressing the growing demand for sustainable construction materials. This study aimed to develop treated raw sewage sludge-based lightweight aggregates with strength comparable to commercially available aggregates. Two methods, namely cold bonding and sintering, were employed for the formation of aggregates. The sintering method produced well-formed and hard aggregates, while the cold bonded aggregates exhibited weakness and disintegrated under the slightest pressure. The optimal mix for quality aggregates was found to be 10%–20% sewage sludge, 70%–80% fly ash, and 10% lime using the sintering method. In the sintering method, an increase in sewage sludge content resulted in the reduction of bulk density and specific gravity by 13% and 4% respectively due to the high organic content in sewage sludge, volatile gas release, and porous structure formation. When 10% to 20% sewage sludge content was added, water absorption of the aggregates also increased by approximately 2%. Physical properties such as individual pellet strength. aggregate crushing value reduced by 18%, 20% respectively and the aggregate impact value increased by about 9%. These aggregates were then used to produce lightweight geopolymer concrete, which exceeded the design strength by 7% for the aggregate containing 20% sewage sludge and demonstrated excellent physical properties. The use of waste-based aggregates offers advantages including savings in cost, sustainability, resource conservation, waste reduction, and reduced environmental impact, making them a valuable alternative to natural crushed stone aggregates in specific applications.

Published: April 2024

Abstract
A biodegradable polymer electrolyte comprising poly (caprolactone) (PCL) and guar gum (GG) doped with lithium perchlorate (LiClO4) was investigated for its application in supercapacitors. The films’ thermal properties, surface morphology, and tensile strength were determined to understand the interaction between the blend system and the salt. Scanning electron microscopic images showed a network of GG channels across the polymer matrix. A unique combo of THF/water as solvent was used for this study as they bring out relaxation in GG segments and compatibility between GG and PCL. The blend polymer electrolyte (BPE) was characterized using conductivity, dielectric, and biodegradation studies. Supercapacitors were fabricated, and electrochemical studies were performed. The optimized BPE was used to fabricate supercapacitors, producing a specific capacitance of 125 F g−1. The time constant was measured at 0.8 s, and a consistent cyclic pattern was observed during galvanostatic charge/discharge studies with 96% Coulombic efficiency. This novel amalgamation of polymeric films holds immense promise for supercapacitor applications.
