Abstract

Child growth is an important indicator in assessing the health status and quality of human resources. One factor that influences child growth is adequate nutritional intake. This study aims to determine the effect of nutritional intake on child growth based on the Height-for-Age Z-Score (HAZ) value in Suka Sari District. The study used a quantitative method with an associative approach. The sample population and the study consisted of 67 children determined using a saturated sampling technique. Data were collected through a nutritional intake questionnaire and height-for-age measurements to obtain HAZ values according to World Health Organization (WHO) standards. Data analysis was performed using IBM SPSS Statistics through validity tests, reliability tests, normality tests, simple linear regression analysis, correlation coefficients, coefficients of determination, and hypothesis testing. The results showed that the research instrument was valid and reliable and the data were normally distributed. Regression analysis showed that nutritional intake had a positive and significant effect on child growth based on HAZ values. The correlation coefficient of 0.988 indicates a very strong relationship, while the coefficient of determination of 97.6% indicates that variations in child growth based on HAZ values can be explained by nutritional intake, while 2.40% is influenced by other factors outside the study. Thus, improving the quality of nutritional intake plays a crucial role in supporting optimal child growth.

Abstract

Excessive online gaming causes sleep deprivation and disrupts health, as addicted individuals often sacrifice rest to continue playing. This study aimed to determine the relationship between online game addiction and sleep disorders in school-aged children. This quantitative correlational study utilized a cross-sectional design with a sample of 148 respondents selected via stratified random sampling. Univariate analysis showed that nearly half of the respondents experienced severe online game addiction (49.32%), while a majority suffered from sleep disorders (60.14%). Bivariate analysis revealed a statistically significant positive correlation between online game addiction and sleep disorders (rs = 0.27, p = 0.001). These findings indicate that higher levels of online game addiction are significantly associated with sleep disorders among school-aged children. Therefore, students should manage their screen time, particularly before bedtime, to prevent sleep disturbances.

Abstract

Students' low awareness of environmental conditions and the lack of learning activities that connect concepts with real-world contexts present key challenges in strengthening environmental literacy in elementary schools. This study aims to develop and test the effectiveness of Canva-based interactive videos in supporting students' environmental literacy. The study utilized the ADDIE development model, involving fifth-grade students as the research subjects. Data were collected through tests, questionnaires, observations, and expert validations, and subsequently analyzed using quantitative descriptive techniques. The results indicated that the developed media achieved a valid category (76.44%) and a highly practical category (97.90%). The improvement in environmental literacy was observed in the cognitive aspect with an N-Gain score of 0.93 (high category), as well as in the affective (99.00%) and behavioral (100.00%) aspects, both falling into the excellent category. The uniqueness of this research lies in the implementation of the media within a local region facing challenges of environmental degradation and low ecological awareness, making the integration of local contexts a key factor in enhancing meaningful learning. Thus, contextually designed Canva-based interactive videos are proven effective in supporting the enhancement of environmental literacy among elementary school students

Abstract

This study was motivated by the need for adaptive and personalized learning support for eighth-grade Informatics students at SMPN 1 Pasaman. This study aimed to examine the effectiveness of an AI chatbot as an interactive tutor in improving personalized learning and Informatics learning outcomes, both partially and simultaneously. A quantitative approach with a quasi-experimental method and a Non-Equivalent Control Group Design was employed. The sample consisted of 63 eighth-grade students, with 31 students in the experimental class receiving AI chatbot integration and 32 students in the control class receiving conventional CBL-based instruction. Data were collected through questionnaires and cognitive tests and analyzed using Multivariate Analysis of Covariance (MANCOVA) to control for pretest scores. The results showed significant partial effects on personalized learning (F = 47.879; p = 0.000), with the experimental group achieving a posttest mean of 66.03, an increase of 19.45 points. A significant partial effect was also found on cognitive learning outcomes (F = 6.248; p = 0.015), with a posttest mean of 81.29, an increase of 27.10 points. Simultaneously, AI chatbot use significantly affected both variables (Wilks’ Lambda = 0.476; F = 31.967; p = 0.000), with an effect contribution of 52.42%. These findings indicate that AI chatbots can serve as interactive tutors that provide adaptive cognitive scaffolding according to individual learning needs

Abstract

Evidence about students’ science achievement can inform course improvement, but descriptive scores should not be interpreted as direct evidence of the effectiveness of learning-management practices. This study profiles basic science achievement among 80 Early Childhood Teacher Education students at Universitas Negeri Manado and uses the profile as an input to a theory-informed evidence-to-management translation framework. A descriptive quantitative cross-sectional design was employed using archived total scores from the Basic Science Concepts course assessment (0–100). Analysis focused on the mean, median, mode, standard deviation, range, and 95% confidence interval. The cohort mean was 77.88 (SD = 3.23), the median and mode were 78, the scores ranged from 71 to 89, and the 95% confidence interval was 77.16–78.59. The narrow observed dispersion indicates a clustered cohort-level score profile, but total scores do not identify domain-specific strengths, misconceptions, or causes of achievement. Accordingly, the management implications are explicitly theory-informed rather than empirical effects. The study proposes an evidence-to-management translation framework that separates what the observed scores directly support from literature-based actions for planning, organization, implementation, learning resources, and monitoring-evaluation. Because complete psychometric documentation and item-level response data were unavailable for re-analysis, findings are restricted to the observed achievement profile and no causal claim is made about science learning management.

Abstract

This study assessed pharmaceutical tablet-manufacturing risk before and after a coordinated process-improvement programme using Failure Mode and Effects Analysis (FMEA). It focused on identifying and ranking failure modes, comparing their Risk Priority Numbers (RPNs), and quantifying residual risk reduction for the AL-MAG 1050 mg tablet line at Alben Healthcare Industries Limited, Nigeria. A retrospective before-and-after industrial risk-evaluation design examined 100 production-batch and quality records from 2022 to 2024. Eight baseline FMEA entries were screened, with four matched failure modes retained: capping, lamination, moisture drift and tool wear. The intervention tightened granule-moisture, blending-time, compression-speed and compression-force windows alongside revised Standard Operating Procedures, process monitoring and tooling controls. Risk reduction was evaluated descriptively using paired RPNs, absolute change, percentage reduction and residual ranking. Capping (50.10%) and lamination (23.57%) dominated the baseline defect burden. Post-intervention RPNs decreased from 280 to 120, 240 to 110, 210 to 95 and 190 to 90, respectively. Reductions ranged from 52.63% to 57.14%, while the aggregate descriptive RPN index declined by 54.89%, from 920 to 415. Despite these improvements, the ranking remained unchanged, with capping retaining the highest residual priority. The findings support continued risk-based surveillance of compression-related failure mechanisms

Abstract

In spite of campaigns by global public health organisations on exclusive breastfeeding for optimal infant survival and development, adolescent mothers often encounter significant socio-demographic, physical and psycho-social challenges that hinder exclusive breastfeeding practices. Academic work and the responsibility for children's care come in conflict in institutional environments such as health technology colleges, and the investigation of socio-demographic determinants among student-mothers becomes an important and critical issue in this context. In this study, Socio-demographic factors associated with exclusive breastfeeding (EBF) among teenage mothers in Anambra State College of Health Technology Obosi, Anambra State, Nigeria were examined. A descriptive cross sectional survey design was used in this study, and 100 teenage mothers aged 16 to 19 years were selected across six departments of study, using multistage sampling technique. A structured questionnaire—validated and well known, called the Sociodemographic Factors Associated with the Practice of Exclusive Breastfeeding Questionnaire (SDFAPEBQ)—was used to collect data and presented high reliability (r=0.82). The descriptive statistics method was used for analysis in SPSS version 27. The results showed that 61.0% of respondents as EBF for six months. The following factors were significantly associated with the higher prevalence of EBF: older age of the teens (18-19 years: 66.7%), the academic level (ND II: 70.4%), marital status (married: 80.6%), and wanting to study only, without any other economic activities (67.7%), multiparity (78.9%). Community Health had the most representation among the departments (28.0%). Overall, a relatively high rate of EBF compliance was observed, which is probably attributed to academic exposure, but socio-demographic factors significantly affected EBF. Targeted institutional and psycho-social support for younger, single and working first-time student-mums should be made a priority in interventions to maintain EBF.

Abstract

This study reports the development and multi-response optimisation of poly(vinyl chloride) (PVC) hybrid composites reinforced with coconut fibre and corncob ash for sustainable, low-load applications. Nine hybrid formulations, combining 3-10 wt.% coconut fibre and 3-10 wt.% corncob ash with a balance of PVC, were fabricated by compression moulding and evaluated for tensile strength, hardness, flexural strength and water absorption; the constituent materials and composites were further characterised by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM). FTIR confirmed a hydrophobic, carbon-chlorine-rich PVC backbone, a hydroxyl-rich lignocellulosic coconut fibre and a siliceous corncob ash, indicating a physically compatible but chemically dissimilar hybrid system. SEM micrographs linked dense, well-wetted microstructures to superior hardness and flexural performance, whereas fibre pull-out cavities and heterogeneous interfaces corresponded with reduced tensile strength and higher water uptake, while XRD confirmed persistent, quartz-dominated crystalline phases that intensified with ash loading. Reinforcement reduced tensile strength from 55.46 MPa (control) to between 19.27 and 36.89 MPa, but increased hardness (up to 34.54 HV, +76.2%) and flexural strength (up to 41.79 MPa, +216.1%) relative to neat PVC, while water absorption rose from 0.60% to a maximum of 1.90%. A mixture-design, desirability-function optimisation that simultaneously maximised flexural strength and hardness while minimising water absorption identified a global optimum of 88.40 wt.% PVC, 5.95 wt.% coconut fibre and 5.66 wt.% corncob ash, predicting 32.14 MPa flexural strength, 29.11 HV hardness and 1.36% water absorption (composite desirability = 0.560). Benchmarked against recent PVC- and polymer-based natural-filler composites, this balanced formulation is proposed for non-load-bearing interior cladding, demonstrating a scientifically defensible route for valorising agricultural residues within sustainable PVC composite design

Abstract

Secondary school students’ poor performance and low motivation in Biology remain persistent educational concerns that may be associated with psychological and motivational factors. Understanding the relationship between students’ self-efficacy and interest in Biology is therefore important for improving learning engagement and outcomes. This study investigated the relationship between self-efficacy and interest in Biology among Senior Secondary Two (SS2) students in public secondary schools in Anambra State, Nigeria. A correlational research design was adopted, involving 637 students selected from 18 public secondary schools through a multistage sampling procedure. Data were collected using two validated four-point rating scales measuring students’ self-efficacy and interest in Biology. The instruments demonstrated acceptable internal consistency, with Cronbach’s alpha coefficients of .810 for self-efficacy and .793 for interest. Measures of sampling adequacy (.910 and .878) and communalities (.918 and .845) further supported the suitability of the instruments. Data were analysed using descriptive statistics, Pearson correlation, multiple regression, and t-test at the .05 significance level. The findings revealed mean scores of 2.7950 for self-efficacy and 2.3507 for interest. A negligible positive correlation was found between students’ self-efficacy and interest in Biology (r = .009). Regression analysis further indicated that self-efficacy did not significantly predict students’ interest in Biology, F(1,635) = 0.051, p = .821. The study concludes that higher self-efficacy does not necessarily translate into greater interest in Biology. Therefore, Biology teachers should combine strategies that strengthen students’ self-efficacy with interactive and interest-enhancing pedagogical approaches to improve student engagement
