Wood, as a basic material for the furniture industry, creates waste problems in the form of wood sawdust. Wood sawdust is a material that can be utilized by processing it through a pyrolysis process to produce liquid smoke and charcoal. Charcoal resulting from sawdust pyrolysis of Azadirachta excelsa, Durio zibhetinus, Swietenia mahagoni, and Coffea sp. wood has different characteristics. Pyrolysis was carried out at 300–350 °C for 6 hours. Characterization was carried out using SEM-EDS and XRD. Based on the research, it is known that the character of the charcoal resulting from pyrolysis using XRD shows that the charcoal composition of each wood has similar characteristics, as indicated by the presence of a broad peak at 2 theta 25° indicating that the charcoal formed has an amorphous structure. In comparison, the 2 theta peaks of 17° and 29° respectively, indicate the presence of lignin and CaCO₃ in charcoal. The morphological structure of the charcoal surface based on the results of SEM analysis shows a similarity in morphology between Swietenia mahagoni and Coffea sp. Wood charcoal with small pore diameters and distances apart, as well as between Durio zibhetinus and Azadirachta excelsa wood charcoal, which resembles a honeycomb structure. The composition of charcoal resulting from pyrolysis shows that the largest component of charcoal is carbon with a percentage of 45.4-56%, calcium with a percentage of 10-15.2%, and oxygen with a percentage of 22.5-38.4%, with minor components in the form of aluminum, boron, silicon, and potassium.

The concept of social economy and its challenges in Latvia
Authors:   Latvia University of Life Sciences and Technologies, Licite-Kurbe Lasma
Published: February 2025

The social economy is a significant component of any economy, which generates economic and social benefits. In Latvia, however, there is no common understanding of the concept of a social economy and the economic actors. The aim is to examine the nature and challenges of the social economy concept in Latvia by giving insight into the historical evolution and nature of a social economy, challenges of defining a social economy and description of the actors of the social economy in Latvia. The study used monographic and descriptive methods, synthesis and deduction for information
gathering, logical systematization and classification, as well as statistical analysis to describe the actors of social economy in Latvia. To obtain in-depth information about concept of social economy in Latvia, expert interviews were conducted. The research specifies social economy actors in Latvia context: associations, foundations, cooperatives and social enterprises. Social economy is an important part of economy, yet it is not fully assessed. In 2023 in Latvia, 27305 organizations operated in the social economy, and their number tended to increase in recent years. Most of the
social economy actors (88%) represented associations. The social economy actors operate in different fields, yet the main ones were arts, entertainment and recreation (5144), real estate operations (3593) and agriculture, forestry and fishing (1108). However, the classification of associations and foundations by kind of activity does not provide accurate information, as many organizations have not indicated their field of activity or have specified “other services”.
Diaphragmatic ultrasound assessment of muscle recovery in patients undergoing general anesthesia: a systematic review and meta-analysis
Authors: Song Seung Eun , Yun So Hui
Published: February 2025

Recently, ultrasonography has been used to evaluate respiratory muscle function in intensive care units. Therefore, we aimed to determine whether this evaluation method applies even to patients recovering from general anesthesia. Randomized controlled trials on assessing diaphragmatic ultrasound undergoing general anesthesia were searched in PubMed/MEDLINE, the Cochrane Central Register of Controlled Trials, and Web of Science databases. Two reviewers will independently screen articles for eligibility and extract relevant data. The risk of bias was assessed using the Cochrane Handbook 5.1.0 for systematic reviews of interventions. Higgins' I2, the heterogeneity statistic Cochrane’s Q, and the corresponding P-values were calculated to measure the heterogeneity among the trials. We used R software (version 3.6.3; R Foundation for Statistical Computing, Vienna, Austria) for all analyses. Of the 165 studies searched, four were ultimately included. The evaluation of the diaphragm for respiratory and muscular recovery was comparable. The standardized mean difference was 1.33 (95% confidence interval, 1.11-1.56). This systematic review evaluates the effectiveness of diaphragmatic ultrasound in assessing respiratory muscle recovery in patients undergoing general anesthesia.
Neurosonology education for undergraduate medical students in South Korea
Authors: Kim Hong Jun , Choi Jay Chol
Published: February 2025

This study assessed the status of neurosonology education for undergraduate medical students in South Korea. An online survey was conducted between September 1 and October 31, 2022, among neurology faculty members at 40 medical schools. The survey consisted of 15 questions on existing neurosonology education and the willingness to integrate it into the undergraduate curriculum. Descriptive analyses were performed using the frequency and percentage distributions. The survey achieved an 80% response rate from 32 participating institutions. Among these, nine (28.1%) included neurosonology lectures in pre-clerkship neurology courses and 15 (46.9%) incorporated them into the neurology clerkship. However, 66.7% of the institutions offering neurosonology allocated less than 1 hour to education, and only 13% of the training involved hands-on courses. The rest relied on live demonstrations and lectures. Of the 17 institutions that did not provide neurosonology education during clerkship, 13 expressed willingness to introduce it in the future. No significant differences were found between institutions that offered neurosonology education and those that did not in terms of student numbers, neurology faculty size, years of establishment, or region. In conclusion, only half of medical schools in South Korea offer neurosonology education, and their programs are limited in time, content, and teaching methods. Expanding neurosonology education requires collaboration among experts in neurosonology, medical education, and other related fields.
Experimental investigation to improve the performance of the PV module using graphene hydrophobic nano coating coupled with top water cooling
Authors: Myilswamy Karthik , Kumaresan Kannan
Published: February 2025

This research aims to enhance the efficiency of polycrystalline silicon solar
photovoltaic panels by addressing the dual challenges of dust accumulation
and temperature variations. The study investigates the effects of applying a
hydrophobic graphene nano-coating on the top surface of the panels to
prevent dust buildup, coupled with a top water-cooling system to regulate
panel temperature. Outdoor experiments were conducted in Coimbatore, India,
from 8:00 am to 4:00 pm under sunny conditions for 40 days. A total of eight
identical photovoltaic panels were tested with various configurations, and
performance parameters such as glass temperature, tedlar temperature, output
power, solar radiation, ambient temperature, and wind speed were recorded.
Experimental results show that the graphene nano-coating reduces panel
temperature by 9.36% compared to the dusty panel and 3.8% compared to the
uncoated, manually cleaned panel by day 40. The nano-coating alone increased
power output and efficiency by 4.16% and 3.3%, respectively, compared to the
uncoated, no-cooling panel. Additionally, the nano-coated, top water-cooled
panels showed improvements of 16.87% in output power and 13.22% in
efficiency compared to the uncoated, no-cooling panel, and 3.11% in power
and 2.82% in efficiency compared to the uncoated, water-cooled panels. These
results demonstrate that the combined application of graphene nano-coating
and water cooling effectively enhances the performance and longevity of
photovoltaic modules by reducing dust accumulation and regulating
temperature.

Authors: Vaskovic Srdjan , Peric Milica , Gvero Petar , Komatina Mirko , Jugovic Milan
Published: February 2025

This study proposes optimal supply chain models for agricultural biomass,
focusing on straw and corn stalks. Four bioenergy chains-corn stalk pellets,
corn stalk chips, straw bales, and straw pellets-were evaluated using
multicriteria decision-making (MCDM) tools and life cycle assessment (LCA).
Key criteria included energy efficiency, investment costs, fuel production
costs, and environmental impacts such as greenhouse gas emissions,
acidification, eutrophication, and particulate matter formation. Results
indicate that straw bales (L3) and corn stalk chips (L2) offer the most
sustainable options, with straw bales demonstrating superior energy
efficiency and lower environmental impacts. The VIKOR method, combined with
the Entropy Weight Method (EWM), identified straw bales as the optimal
supply chain under various weighting scenarios. These findings provide
actionable insights for sustainable bioenergy development and policy
formulation.
Experimental analysis of CI engine performances and emissions operating with synthetic fuel extracted from industrial oil
Authors: Mimoun Sofiane , Bencherif Mohamed , Larbes Nasreddine , Leftas Tewfik , Kaced Amel
Published: February 2025

This paper deals with an experimental analysis of performance and emissions
of a single cylinder, air cooled, direct injection, compression ignition
engine using synthetic fuel extracted from Tilia B233 refrigerator
lubricating oil and waste cooking oil biodiesel. Biodiesel and synthetic
fuel are produced by transesterification process using methanol and
potassium hydroxide. Physical properties as well as liquid density, liquid
viscosity, total acidity number and flash point are measured. Physical
properties and their blends are compared with conventional diesel fuel
properties. A first insight to the results indicates that, unlike biodiesel,
synthetic fuel which is distinguished by their its low acidity, which
enables its storage. In addition, their viscosity is quite high and require
the use of synthetic fuel blends with diesel fuel. A careful investigation
according to current limitations and standards leads us to a direct engine
test with a maximum blending rate of 50%. Thus, blends are achieved by
mixing 15%, 30% and 45% of biodiesels with a complementary amount of
commercial diesel fuel. The experimental results are obtained on single
cylinder diesel engine operating at 1600 rpm for a wide range of loads.
Brake specific fuel consumption, specific NOx and CO emissions are compared
for each blend with those obtained by conventional diesel fuel.
Influence of volumetric radiation properties on natural convection in the low mach number approximation
Authors: Rachedi Nesrine , Guellal Messaoud , Bouafia Madiha
Published: February 2025

The study aims to investigate the dynamics of fluid flow and thermal energy
exchange within a 2D differentially heated cavity using the low Mach number
approximation. Specifically, it seeks to investigate the occurrences related
to natural convection and thermal radiation in a medium that exhibits
absorption, emission, and scattering properties and exposed to a significant
temperature difference. This methodology is applied within the framework of
the low Mach number model of the Navier-Stokes equation. The interaction of
momentum, energy, and radiation transfer equations within the cavity is
addressed through an iterative approach that combines discrete-ordinates and
finite volume methods enhanced by the SIMPLER algorithm. The obtained
findings show that the LMN model overestimates radiative transfer, with
higher radiative power in the absorbing-emitting case. Transparent media (?
= 5) result in the highest heat transfer, while lower opacity favors the
absorbing-diffusing medium. Flow intensity increases with albedo, and
isotherms deform due to strong fluid dynamics. At high opacity, heat
transfer is greater in transparent media, with lower velocities in more
diffusing media.
Influence of multiple factors on calcined coal kaolin and numerical simulation of rotary kiln
Authors: Wang Jiale , Kao Hongtao
Published: February 2025

Coal kaolin, as an important industrial raw material, is used in the
production of artificial Molochite sand whose application is of great
potential for high-end castings due to its ability to significantly reduce
the cost of mineral sand and improve the quality of sand mold. In this
paper, the key factors in the calcination of coal kaolin were systematically
analyzed with a three-factor, four-level orthogonal test, and the test
factors were rotary kiln temperature, particle size, and residence time of
materials. The optimal calcination parameters determined by range analysis
were a temperature of 1500?C coal kaolin, a particle size of 4mm-8mm, and
residence time of 1.5 hours. Analysis of variance showed that temperature
had the most significant effect on the calcination effect, followed by coal
kaolin particle size. In contrast, the effect of residence time of materials
was relatively small. The test showed that the basic needs of producing 60%
mullite, the standard percentage, could be met at 1100?C. In order to verify
the required coal feed and temperature distribution in the actual rotary
kiln, a rotary kiln model was established by numerical simulation technology
to simulate the actual conditions. The results showed that the rotary kiln
has an average temperature of 1159?C and a maximum temperature of 1428?C when
the coal consumption is 1.5 kg/s, which meets the temperature requirements
for 60% mullite.
Influence of feed flow rate and feed concentration on the ammonia absorption refrigeration system
Authors: Hu Yu , Sun Xiaolin , Wang Jinfeng , Zhang Jianguo , Zhou Zhigang
Published: February 2025

The absorption refrigeration system is a type of heat-driven system. The
working pairs used most commonly are the lithium bromide-water and the
ammonia-water pairs. Compared to the lithium bromide-water pair, the
ammonia-water pair can achieve lower evaporation temperature and has a wider
range of applications in industry. Feed flow rate and feed concentration are
key factors affecting the system's performance, which have significant
effects on the ammonia concentration and flow rate at the outlet of the
distillation tower, as well as the COP of the system. In this paper, the
relationship between feed concentration, feed flow rate, and system
performance is investigated by numerical simulation and experimental study.
The results show that increased feed concentration can effectively improve
the ammonia concentration at the outlet of the distillation tower. At the
same time, there is an optimal feed flow rate in the system, and when the
feed flow rate rises gradually to the optimal value, the COP of the system
also increases. When the feed flow rate exceeds the optimal value, the
ammonia concentration at the outlet of the distillation tower will be
rapidly reduced, as well as the COP of the system.
Numerical investigation of effect of fill ratio and inclination angle on a U-shaped elliptical gravity heat pipe thermal performance
Authors: Chen Yang , Chen Guofei , Xu Huijie , Zhou Jianqiu
Published: February 2025

As electronic devices become increasingly compact, effective thermal
management is crucial for performance. This study establishes a model of a
U-shaped elliptical gravity heat pipe with dual heating ends and a single
cooling end. Through computational fluid dynamics (CFD) simulations, the
impacts of filling ratio and inclination angle on the thermal transfer
capacity for the heat pipe were investigated. The results indicate that the
evaporator surface temperature and thermal resistance of the heat pipe
initially decrease and then increase with an increasing filling ratio.
Within the inclination range of 10? to 90?, the evaporator
surface temperature and thermal resistance gradually decrease. The optimal
filling ratio is found to be 65%, and the optimal inclination angle is 90?.
Furthermore, it was observed that higher heat input intensifies the effects
of filling ratio and inclination angle affecting heat
pipe thermal performance. These findings highlight the critical role of these
parameters in optimizing heat pipe performance under varying heat inputs.
Managing fuel consumption and emissions for hybrid electric vehicles through optimization of engine operation
Authors: Milicevic Stefan , Blagojevic Ivan
Published: February 2025

This paper presents a multi-objective optimization framework for improving
internal combustion engine performance in hybrid electric vehicles,
specifically targeting the minimization of fuel consumption and emissions
(CO, NOx, HC, PM). The proposed method integrates normalized objective
functions with weighted factors to develop a unified performance index,
facilitating the simultaneous optimization of multiple conflicting
objectives. Utilizing the NSGA-II algorithm, a diverse set of Pareto optimal
points is generated, each representing different trade-offs between the
objectives. The study?s results demonstrate significant improvements in
engine performance through the application of the unified ICE operation map,
showcasing a notable reduction in emissions with only a slight increase in
fuel consumption. The methodology was validated via MATLsimulations on
two case studies involving parallel and series hybrid electric vehicles,
employing a custom synthesized drive cycle for energy management strategy
evaluation. The unified map enabled real-time control and efficiency
improvements by balancing different emission parameters, thus optimizing ICE
operation across various conditions.
Absorption coefficientofco2and first-order approximation of radiative forcing
Authors: Ostrogorsky Aleksandar
Published: February 2025

CO2 is one of the two primary greenhouse gasses and the source of carbon
needed for photosynthesis and life on Earth. The spectral absorption
coefficient ?(?)[m-1] is a fundamental property of CO2.It is required for
modeling heat transfer at high temperature in furnaces, heat engines, wild
fire etc. and in the atmosphere at ~300 K. Using a FTIR spectrometer, infrared
absorbance A(?) spectra of CO2were measured with 0.5 cm-1resolution. All
measurements were conducted at 295 K. The spectra cover the wavelength range
2 ?m<?<18.2?m and the pressure range 0.04 atm<p<3atm. The spectra were used
to determine the spectral absorption coefficient ?(?) in the bands adjacent
to the peaks 2.7 ?m, 4.26?m and 15?m. The spectraofCO2in air are also
presented. A first-order approximation-model of the radiative forcing, ?q, is
presented. The FTIR spectra confirm that 400 ppm of CO2is sufficient to
saturate absorption in the central PQR region of the 15 ?m
band. Consequently, radiative forcing is controlled by the wings(edge)
regions of the 15 ?m band. 100 % increase inCO2concentration will cause
radiative forcing, ?q400ppm to 800ppm=2.79Wm-2,andtemperature increase ?T~
0.7K. Tenfold (1000 %)increase in CO2concentrationwill increase radiative
forcing by ~ 1.8x, so that ?q400ppm to 4000ppm=5.03 Wm-2and ?T~ 1.2 K.
Optimal control, construction, and analysis of λ-Bernstein Bézier surfaces for quasi-harmonic functional
Authors: Buttar Mariyam , Ahmad Daud
Published: February 2025

In this article, we investigate a novel construction scheme for ?-Bernstein
B?zier surfaces and illustrate it with biquadratic and bicubic cases to
demonstrate their geometric characteristics and their applications. The
primary objective is to investigate how the shape parameter ? improves
control over surface smoothness and facilitates an optimal solution in
surface design. We examine the geometric properties of these surfaces,
including mean and Gaussian curvature, shape operator coefficients, and
Gauss-Weingarten coefficients. We also analyze the extremal conditions for
?-Bernstein B?zier surfaces derived from the vanishing condition for the
gradient of the quasi-harmonic functional. Integral formulations based on
Bernstein polynomials enable precise computation of the vanishing gradient
condition, allowing us to determine the constraints on interior control
points in terms of known boundary control points. Graphical illustrations
validate the approach by providing a better understanding of the geometric
properties of these surfaces, including improved surface smoothness and
design flexibility. They effectively showcase the behavior of ?-Bernstein
polynomials and their corresponding surfaces. Computational results
demonstrate the effectiveness of this method for applications in computer
graphics, computational geometry, computer science, and engineering,
offering a robust framework for analyzing and generating optimal surfaces,
contributing to advancements across various scientific disciplines.

Authors: Hughes Allyson S. , Uddin Kashif , Krupar Meghan , VanDyke Erika , Stuckey-Peyrot Heather L.
Published: February 2025

People with type 1 diabetes are living longer and, by 2030, one-fifth of the U.S. population will be older adults ≥65 years of age. This qualitative study addressed the scarcity of research on the experiences of aging people with type 1 diabetes. Nineteen older adults (mean age 65.63 ± 6.27 years, mean duration of diabetes 36.97 ± 18.94 years) were interviewed about their disease management challenges and gaps in available resources. Identified themes included positive and negative changes over the life span resulting from 1) diabetes-related psychological health 2) hypoglycemia unawareness, and 3) health care barriers. Responses also suggested that a lack of support may lead to poorer health outcomes and greater diabetes distress. Additional research is needed to better understand these issues and to inform the creation or tailoring of public policies to support older adults with type 1 diabetes.
Microstructure characteristics and cavitation erosion resistance of Co-based coating fabricated via laser cladding
Authors: Zhang Jie , Xu Qing , Ding Qiang , Duan Jiawei , Xu Yajing , Ji Fengtao
Published: February 2025

Marine centrifugal pumps are important mechanical equipment widely used in ships, but they are often damaged due to cavitation. In this paper, a Co-based coating was prepared on the surface of a substrate via laser cladding technology. The microstructure characteristics and phase composition of the coating were analyzed by an optical microscope (OM), a scanning electron microscope (SEM), and an x-ray diffractometer. Ultrasonic vibration cavitation tests were used to test the cavitation erosion resistance of the coating in NaCl solutions with different concentrations (0, 2.5, and 3.5 wt. %).The experimental results showed that the coating is mainly composed of γ-Co, (Co,W)6C, and Cr23C6. After 12 h of cavitation testing in different concentrations of NaCl solution, the Co-based coating exhibited better anti-cavitation performance than the 316 stainless steel substrate. The corrosion rate of the Co-based coating was significantly lower than that of the 316 stainless steel substrate. In addition, the experimental results also showed that the higher the concentration of NaCl, the faster the weight loss rate of the Co-based coating and the more pronounced the degree of surface cavitation. Although a dense oxide protective layer is easily formed on the surface of the Co-based coating and effectively inhibits the further erosion of the corrosive medium, with the increase in the concentration of NaCl solution, the erosion by chloride ions is more likely to destroy the dense protective layer and formed cavitation holes.

Etiopatogenia de la fibrosis pulmonar idiopática. Una revisión bibliográfica actualizada
Authors:   Universidad Técnica de Machala Ecuador, Armijos Maldonado Jennifer Cleotilde
Published: February 2025

La fibrosis pulmonar idiopática (FPI) es una enfermedad pulmonar intersticial crónica caracterizada por la formación de tejido cicatricial en los pulmones, lo que conduce a una insuficiencia respiratoria progresiva. A pesar de los avances en su comprensión, la etiología sigue siendo desconocida, por lo cual, el objetivo de esta revisión es examinar y resumir la literatura científica más reciente sobre la etiopatogenia de la FPI.

Los estudios han identificado mutaciones en genes relacionados con la biología de los telómeros, las proteínas del surfactante y la reparación del daño celular, lo que sugiere una predisposición genética en algunos casos. Además, la exposición a agentes nocivos como el humo del tabaco, partículas inhaladas, la presencia de infecciones virales y comorbilidades como la enfermedad de reflujo gastroesofágico se ha asociado con un mayor riesgo.

La patogenia de la FPI implica una intrincada interacción entre el daño epitelial alveolar, la inflamación, la remodelación de la matriz extracelular y la alteración de vías de señalización celular. El daño repetitivo al epitelio alveolar conduce a una respuesta inflamatoria anormal, la activación de fibroblastos y la deposición excesiva de componentes de la matriz extracelular, lo que resulta en la formación de tejido fibrótico.

Published: February 2025

The sea dominates the East Flores Regency landscape, which has a sizable marine area and undoubtedly great potential for marine products. This study determines which marine commodities have the greatest development potential. 2016–2022 data on the volume of marine commodities production, the value of commodities, and confirmatory data gathered through in-person interviews with key stakeholders in the business are utilized. The foundations for a robust policy formulation are the contribution classification, static and dynamic location quotients, and location quotient classification, which are cross-referenced and elaborated by breaking down the constraints and constructing the development strategies for the commodities structured from the interviews. The study finds that skipjack, pearls, common dolphinfish, and long-jawed mackerel are the prospective commodities to be developed in the future. The development was hampered primarily by nature-related constraints, including sea weather, storms, and pandemics. The progress necessitates increased government support as well as durable, long-term targeted policies.

The journal impact factor (JIF) is a measure that provides a ratio of citations to a journal in a given year to the citable items in the prior two years. The JIF has become a symbol and measure of a journal's prestige in the modern world of peer-reviewed publications. The difficulty and importance for a peer-reviewed journal to obtain an impact factor has been highlighted in numerous medical journals. Irving H. Sher and Eugene Garfield were the first to create the concept of the impact factor of a peer-reviewed journal. According to Eugene Garfield (2006), the JIF is based on two elements: the numerator, which is the number of citations in the current year to items published in the previous two years, and the denominator, which is the number of substantive articles and reviews published in the same two years. Scientists around the world may notice that as of 2024, the JIF is calculated not only by Clarivate, but also by exaly. Clarivate is known for being the company that calculates the JIF, using data from its Web of Science product family, that also includes services/applications such as Publons, etc. In this editorial, we will explain in more detail why the JIF is important both for the peer-reviewed journals published in Ukraine and for Ukrainian authors. Also, let's also explain how both the impact factor calculated by Web of Science and the impact factor calculated by exaly can be useful. The article presents the experience of the Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology in assigning it an impact factor calculated by the exaly. The advantages for Ukrainian authors of publishing articles in the journals with an impact factor are presented. According to the Order of the Ministry of Healthcare of Ukraine of February 22, 2019, No. 446, publication of an article or review in a journal with an impact factor allows an oral and maxillofacial surgeon to be awarded 20 or 30 continuing professional development (CPD) points. The CPD points obtained are necessary for doctors to the annual review of their personal educational portfolio with CPD points, certification, confirmation or obtaining a new doctor’s category. In summary, the peer-reviewed journal that has received an impact factor automatically becomes a kind of provider of CPD activities for healthcare professionals, for which CPD points are awarded.

This study explores the role of exaggeration in animation, focusing on its impact on believability and storytelling, particularly within Ping Pong The Animation (2014). Despite its longstanding use in animation, the significance of exaggeration still needs to be explored. By applying the 12 Principles of Animation and Laban Movement Analysis (LMA) theory, this research examines how exaggerated movements, in conjunction with LMA's Shape and Effort, enhance the narrative by intensifying characters' actions, expressions, and emotions during high-stakes ping pong matches. The deliberate exaggeration amplifies tension, excitement, and energy, making the sequences visually compelling and emotionally resonant. The methodology aims to provide animators with insights into creating believable movements in animation, even within fictional worlds. The findings suggest that exaggeration is a crucial tool for enhancing the appeal and authenticity of animated sequences, offering a valuable example for the animation industry. This research contributes to the understanding of exaggeration's role in animation and serves as a reference for future studies, highlighting the importance of effective movement in engaging audiences and creating immersive, artistic animations.

This study explores innovative strategies for preserving the rich cultural heritage of Malay traditional attire, with a particular emphasis on the Samping Songket, a garment deeply rooted in Malay identity and tradition. With younger generations exhibiting declining awareness and appreciation for this intricate cultural artifact, the research addresses the urgent need to bridge this gap through the integration of technology-driven educational tools. Central to this initiative is the development of Hikayat Putera Indra, a digital pop-up augmented reality (AR) book designed to revive interest by blending storytelling with hybrid animation techniques. This interactive book not only narrates the history and significance of Samping Songket but also provides step-by-step demonstrations of traditional tying methods, transforming passive learning into an immersive experience. By incorporating 2D and 3D animation alongside AR technology, the project creates a dynamic platform that appeals to children and teenagers aged 10 to 17, fostering curiosity and engagement with Malay heritage. The study adopts a mixed-methods approach, combining semi-structured interviews with cultural experts from PERNILAM to extract valuable insights into the symbolism and historical narratives of Samping Songket. Additionally, structured questionnaires targeting 25 youth respondents measure awareness levels and interest in learning traditional tying techniques. This comprehensive research design ensures a robust analysis, yielding triangulated data that highlights a significant gap in knowledge regarding traditional attire. Findings reveal that the use of AR significantly enhances understanding and engagement, offering an effective means to safeguard intangible cultural heritage. Both expert evaluations and youth feedback affirm the project's success in reigniting interest and appreciation for Malay traditional attire. Ultimately, Hikayat Putera Indra exemplifies how modern technology can serve as a vital tool for cultural preservation, fostering intergenerational connections and ensuring that the artistry of Samping Songket endures as a cherished legacy for future generations.
