As we navigate the fast-paced era of urban expansion, the integration of machine learning (ML) and remote sensing (RS) has become a cornerstone in environmental management. This research, focusing on Silchar City, a non-attainment city under the National Clean Air Program (NCAP), leverages these advanced technologies to understand the urban microclimate and its implications on the health, resilience, and sustainability of the built environment. The rise in land surface temperature (LST) and changes in land use and land cover (LULC) have been identified as key contributors to thermal dynamics, particularly focusing on the development of urban heat islands (UHIs). The Urban Thermal Field Variance Index (UTFVI) can assess the influence of UHIs, which is considered a parameter for ecological quality assessment. This research examines the interlinkages among urban expansion, LST, and thermal dynamics in Silchar City due to a substantial rise in air temperature, poor air quality, and particu.....

Limonoid group belongs to triterpenoid that has undergone further oxidation accompanied by the loss of four carbon atoms to form a furan ring in the chain. This limonoid compound is often found in the Chisocheton genus. Limonoid compounds have been known as compounds with high structural variations and this makes limonoids have diverse and interesting activities, including cytotoxic and anticancer. In the course of our continuing study for limonoid constituents that have cytotoxic activity against cancer cell lines, methanol extract of stem bark from the Chisocheton pentandrus plant provides significant activity. The methanol extract was separated using various chromatographic techniques in the normal and reverse stationary phase to produce four azadirone-type limonoid compounds (1-4). The elucidation structure of 1-4 was determined using spectroscopic methods including, UV-Visible, IR, and 1D-NMR as well as optical rotation. All four known compounds were established as trichilenone ac.....

One of the skills needed in the 21st century is critical thinking skills that need to be developed for secondary school students. Currently, upper-secondary students’ critical thinking skills are still low. To overcome the problem, website-based E-module learning media was developed using a STEM approach with a Problem-Based Contextual Learning model with virtual experiments using PhET. The aim of developing this website-based E-Module media is to improve students’ thinking skills on thermochemistry learning materials. The development model is 4-D. Data collection in this study was gained from three schools representing schools in the high, medium, and low categories in Surakarta, Indonesia. In this research,216 students were involved as the subjects at the development module implementation stage. The results of expert validation of the material, language, and media modules are suitable for use with a score of 90.03% categorized as very good. In the feasibility test, the score was .....

Purpose This study investigates how Digital Game-based Learning (DGBL) impacts the development of product innovation skills among undergraduate students, comparing the performance of students across different disciplines—Applied Arts (AA) and Applied Sciences (AS). Methodology The study involved 80 undergraduate students: 40 students pursuing an AA degree and 40 pursuing an AS degree. The design of the innovation game incorporated cognitivist learning strategies based on Bloom’s taxonomy. Innovation skills were evaluated through an open-ended achievement test. Findings The study revealed that DGBL effectively enhances product innovation skills by integrating cognitive strategies, and Bloom’s Taxonomy into guided answers, and open-ended achievement tests. AS students excelled in problem identification and idea creation, while AA students emphasised psychological, emotional factors and visualisation representation. Significance The findings suggest promoting interdisciplinary colla.....

Objective: Sexual  education  for  children  is  crucial  as  it  aids  in  their  understanding  and appreciation of their bodies. This research aims to develop a Body Safety Module as a teaching tool  for  primary  school  students.  The  modules  were  analyzed  to  determineperception  of usability as well as their effectiveness. Methods:This study focuses on design and development research, adopting the five phases in the ADDIE model for the module development process. To evaluate the module’s effectiveness, 205  respondents  were  randomly  chosen  to  complete  a  questionnaire.  Furthermore,  an additional 71 pupils participated in pre-and post-effectiveness tests. This study examined three specific aspects of validity: content validity, questionnaire validity, and the effectiveness of pre and post-test. Results and conclusion:The module received extensive professional review and agreement, showing  a  93.73%  agreement  on  the  valid.....

Accuracy and speed are critical factors that influence tennis performance. Various studies have examined speed, but less attention has been given to understanding the probabilistic structure of errors (i.e., accuracy). Tennis, a racquet sport requiring high physical fitness during competition, emphasizes the importance of both ball accuracy and speed for success. This is especially true for young male competitive tennis players. This study aimed to analyze the ball accuracy and ball speed of running groundstrokes on a clay court. Sixteen males at national-level junior tennis were assessed (age: 15.50 ± 0.63 years; height: 178.44 ± 8.08 cm; body weight: 67.25 ± 7.72 kg; body mass index: 21.12 ± 1.93 kg/m2). All participants measured running groundstroke performances by hitting a ball to a target square and hitting it as fast as possible by using a ball machine that fed 10 balls at a velocity of 60 km/h, with a 2-minute break between trials. The running groundstroke variables measure.....

Background: Since the turn of the 21st century, research on an inquiry-based approach in science education has increasingly been geared towards the integration of technology, primarily focused on secondary and tertiary education. Thus far, no study has reviewed research on a technology-integrated, inquiry-based approach in the specific context of primary science education. Purpose & Method: This scoping review has two primary aims: to investigate the characteristics of the technological interventions used in previous research that employed an inquiry-based approach in science education and to examine the effects of this integrated approach on primary pupils’ learning in science. Fifteen articles from science education journals based on Scimago Journal Rank in the first quartile of 2020 and the Scopus database of the years 2017 to 2021 were extracted and reviewed using narrative and thematic analysis. Findings: The review navigates research that has focused on the development of inqui.....

Artificial intelligence (AI) has become a crucial element of modern technology, especially in the healthcare sector, which is apparent given the continuous development of large language models (LLMs), which are utilized in various domains, including medical beings. However, when it comes to using these LLMs for the medical domain, there’s a need for an evaluation platform to determine their suitability and drive future development efforts. Towards that end, this study aims to address this concern by developing a comprehensive Multi-Criteria Decision Making (MCDM) approach that is specifically designed to evaluate medical LLMs. The success of AI, particularly LLMs, in the healthcare domain, depends on their efficacy, safety, and ethical compliance. Therefore, it is essential to have a robust evaluation framework for their integration into medical contexts. This study proposes using the Fuzzy-Weighted Zero-InConsistency (FWZIC) method extended to p, q-quasirung orthopair fuzzy set (p, .....
