Abstract

Palm kernel shell (PKS), a major by-product of the palm oil industry, has emerged as a promising sustainable feedstock for solid biofuel briquettes. This study presents a systematic review of PKS briquettes, emphasizing their thermal properties, briquetting technologies, pretreatment methods, environmental and economic impacts, and future prospects. A PRISMA-based methodology was applied to ensure transparent identification, screening, and synthesis of relevant peer-reviewed studies on PKS briquette production and performance. The review indicates that PKS briquettes generally possess high calorific value, substantial fixed carbon content, and competitive combustion performance compared with other biomass fuels. Advances in densification techniques and pretreatment processes have improved fuel quality, durability, and energy efficiency. Despite these strengths, several research gaps persist. Standardized data on thermal conductivity and heat transfer remain limited, and comparative assessments with conventional fuels such as coal and firewood are insufficient. Moreover, inconsistencies in experimental conditions hinder cross-study evaluation, while emissions characteristics and large-scale industrial feasibility are underreported. By consolidating current findings and identifying critical knowledge gaps, this review offers a structured foundation for future research and informed policymaking, supporting the integration of PKS briquettes into sustainable energy and circular economy strategies in palm oil–producing regions.

Abstract

Despite the expanding application of Augmented Reality (AR) in educational settings, rigorous empirical investigations into its efficacy for enhancing reading comprehension among English as a Foreign Language (EFL) learners remain limited, particularly in the Indonesian higher education context. This study employed a quasi-experimental mixed-methods design to examine the impact of Assemblr EDU, an AR-based instructional application, on the reading comprehension performance of 104 undergraduate EFL learners at the B1 proficiency level. Utilizing the Dialang reading assessment and one-way analysis of covariance (ANCOVA), the quantitative findings revealed a statistically significant difference in posttest scores between the experimental group (M = 15.61) and the control group (M = 12.43), with a large effect size (partial η² = .919, p < .001), thereby affirming the pedagogical advantage of AR integration in reading instruction. Semi-structured interviews were conducted with six experienced EFL lecturers to contextualize the quantitative results further. Thematic analysis indicated that AR-supported instruction enhanced student motivation, vocabulary acquisition, and comprehension through multimodal interaction. However, technological constraints and limited access to digital resources were noted as implementation barriers. The study provides robust evidence supporting the efficacy of AR in improving EFL reading outcomes. It underscores the need for systemic support, including infrastructure readiness and targeted teacher training, to optimize its integration. These findings contribute to the theoretical and practical discourse on technology-enhanced language learning and offer implications for the design of future AR-based pedagogical interventions in EFL contexts.
