Abstract

Access to quality education remains a challenge in developing nations, including Indonesia. Augmented reality (AR) has emerged as a promising tool to address this gap. This review aimed to examine AR applications in education from 2001 to 2024, focusing on their impact on learning outcomes and accessibility. The study analyzed 171 articles selected through a systematic search in databases like scopus and IEEE explore. Key aspects reviewed include AR tools, applications, evaluation methods, and target demographics. Findings highlight ARs effectiveness in STEM education, vocational training, and cultural learning through features like 3D visualizations, interactive simulations, and animations, enhancing engagement and skill acquisition. AR aligns with sustainable development goals 4 (quality education), 9 (industry, innovation, and infrastructure), and 10 (reduced inequality) by improving access to education and reducing inequalities. However, challenges such as inadequate teacher training, limited infrastructure, and the need for localized content hinder broader implementation. The review concludes that AR tools should address pedagogical and contextual needs for optimal impact. Recommendations include expanding teacher training, improving access to technology, and developing culturally relevant content. Future research should explore scalable, long-term AR solutions to enhance global education

Abstract

The problem that often occurs during the learning process is that students feel bored and do not focus on the material taught by the teacher. Hence, students are not active during the discussion process, and these problems result in low student learning outcomes. In this case, the teacher seeks to arouse student interest and motivate students to be more enthusiastic about learning using the Lectora Inspire application-based learning media. This type of research was research and development (R&D) using the 4D model consisting of 4 stages: define, design, develop, and disseminate. The define stage was carried out by analyzing to obtain information in the field. The design was done by making an e-module design; the development stage is developing e-modules using Lectora Inspire and conducting assessments and trials. The final stage was dissemination, namely disseminating e-modules. After being validated, the research results showed that modules based on Lectora inspire applications in the colloid system course were declared feasible after being validated by material experts, media experts, teacher responses, and student responses. Assessment of material and media experts with an average percentage of 90.41% with the appropriate/valid category, the percentage of teacher responses was 84.76% with very high criteria, and the percentage of student responses was 83.54% with very high criteria. Based on the results of the n-gain score of 0.62 with a moderate category, the Lectora inspire-based e-module effectively improves learning outcomes. It can be concluded that the electronic module based on the inspirational Lectora application as an interactive learning medium effectively improves student learning at school.

Abstract

Latent fingerprint visualization is a critical technique in modern forensic science that requires effective and environmentally sustainable coloring agents. This study reports synthesizing and characterizing a novel dyeing agent based on Cochineal insect extract combined with silica derived from salak (Salacca zalacca) bunch waste. It evaluates its application in fingerprint visualization. Cochineal extract was obtained via stepwise heating in a polar solvent, while silica was synthesized through carbonization, demineralization, destruction, and neutralization. The SiO–Cochineal nanoparticles were prepared using a stepwise thermal immobilization method, resulting in covalent bonding between the pigment and silica matrix. Structural and functional group characterization using FTIR confirmed the presence of Si–O–Si, O–H, and C=O groups, indicating successful integration. Application tests on latent fingerprints demonstrated that the composite powders produced sharp and distinct ridge patterns, particularly on non-porous substrates such as glass and optical discs. These findings suggest that SiO-Cochineal-based powders are effective for forensic applications and represent a promising green alternative for latent fingerprint visualization.

Abstract

The uniqueness and permanence of patterns make fingerprints one of the most significant forensic tools for individual identification. The issue is that conventional fingerprint powders, frequently used today, pose serious health and environmental risks due to their use of toxic chemicals. This novel study utilizes sustainable and innovative techniques to investigate the effectiveness of beetroot fruit extract for latent fingerprint visualization. Zinc oxide (ZnO) nanopowders were synthesized using a green synthesis method, having beet fruit extract as an aqueous solvent. For applications on porous and non-porous surfaces, the fabricated ZnO was characterized using Fourier Transform Infrared (FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray (EDX) analysis up to October 2023. Thirty samples were provided to perform latent fingerprint analysis. The results show that ZnO nanopowders synthesized using beet fruit extract could provide safe, non-destructive, and efficient visualization of the latent fingerprints. Of the six fingerprint patterns examined, the most common was the Plain Whorls pattern, which represented 47% of prints identified. These results highlight beet fruit extract's natural potential and efficacy as a contrast agent for imaging latent fingerprints. This clean approach can provide a novel alternative for forensic biology, characterized by low toxicity, sustainability, and high efficacy, which can lead to a safe forensic practice.

Abstract

Fingerprints are a reliable means of forensic identification because ridge patterns are unique and permanent. Conventional fingerprint powders, however, may contain hazardous ingredients that pose health and environmental risks. This study synthesized zinc oxide (ZnO) nanoparticles via a green route using durian peel (Durio zibethinus) extract and evaluated their potential as an eco-friendly latent fingerprint developer. ZnO nanoparticles were characterized by FTIR to identify functional groups, SEM to examine morphology and particle size, and EDX to verify elemental composition. The biosynthesized ZnO showed semi-spherical to granular particles with sizes of 40–90 nm and no severe agglomeration. FTIR indicated hydroxyl and carbonyl groups from durian peel biomolecules, suggesting their role as reducing and stabilizing agents. EDX confirmed dominant Zn (72.5%) and O (15.2%) signals, supporting high purity ZnO formation. Latent fingerprint development was tested using prints from 40 respondents on porous surfaces (black cardboard and oil paper) and nonporous surfaces (microscope slide, aluminum foil, and compact disc). The ZnO nanopowder produced clear ridge patterns and higher contrast on nonporous substrates, while conventional powders tended to leave residues and may require less safe reagents. These results indicate that durian peel derived ZnO nanoparticles are a promising, economical, and environmentally friendly alternative for latent fingerprint visualization and provide added value for agricultural waste utilization in forensic applications.
