Abstract

The integration of energy conversion technologies in hygiene systems plays a crucial role in enhancing energy efficiency and reducing overall power consumption. This study explores various approaches to optimizing energy conversion within hygiene applications, including heat recovery systems, biogas utilization, and solar energy integration. The findings indicate that the use of exhaust heat recovery in HVAC systems can reduce energy consumption by up to 25%, while biogas from organic waste can lower fossil fuel dependence by 30%. Additionally, the integration of solar energy in sterilization processes has been shown to increase efficiency by 40% in industrial settings. Moreover, the study highlights that combining multiple energy conversion technologies results in greater energy savings compared to standalone implementations. A system integrating heat recovery and solar energy, for instance, demonstrated a 50% reduction in energy consumption within industrial sanitation applications. Despite these advantages, challenges such as high initial investment costs and limited regulatory support hinder widespread adoption. The research emphasizes the need for an optimization-based approach that considers technical, economic, and regulatory aspects to maximize efficiency and sustainability. By addressing these factors, industries can enhance hygiene system performance while reducing operational costs and environmental impact. Future research should focus on developing specific optimization models for various industrial and medical sectors and assessing the long-term implications of implementing these technologies at scale.

Abstract

The development of small-scale renewable energy manufacturing in developing countries significantly contributes to sustainable energy access and local economic independence. However, this manufacturing sector poses occupational health and safety (OHS) risks that are often overlooked, particularly regarding chemical exposure, technical dust, and informal working conditions. This article presents a systematic literature review to identify these risks from a public health perspective and assess the social, economic, and regulatory factors influencing working conditions. Findings reveal that OHS aspects are frequently neglected in small-scale renewable energy technology development, potentially leading to long-term health impacts, especially for women and young workers in the informal sector. The article recommends developing contextualized OHS guidelines, safety training programs, and healthy workspace design as mitigation strategies. A cross-sectoral approach involving government, academia, and industry stakeholders is essential to ensure safe and sustainable renewable energy manufacturing.

Abstract

Highlighting the importance of fundamental motor skills encompassing balance, locomotor, and manipulative abilities in the physical development of elementary school children. This study aims to ascertain and provide a better understanding of holistic fundamental motor skills, aiding in identifying children needing continuous intervention. This quantitative descriptive study employs a cross-sectional approach involving 310 respondents of elementary school students aged 7 to 9 years old. The research instrument comprises an assessment rubric with performance observations encompassing eleven types of fundamental motor skills. Ideal mean formula and ideal standard deviation are utilized to analyze data regarding the proficiency levels of each motor skill category. Additionally, an Independent Sample t-test is employed to ascertain the data differences among elementary school students based on gender. The research findings indicate that the elementary school students' fundamental motor skills have an average performance assessment mean of 32.14 (36.12%), with the majority falling into the "good" category. The average performance score of male students is higher than that of female students, with a mean of 30.32 and a standard deviation of 3.590, while the average performance score of female students is 28.48, with a standard deviation of 3.208. They explain the variation in motor skills among elementary school students aged 7 to 9. Most students exhibit proficient skills, although some fall into the unsatisfactory motor skill category. On average, male students demonstrate higher motor skills compared to female students.

Abstract

Smoking is a known risk factor for impaired lung function, even among physically active individuals. The harmful substances contained in cigarettes are known to disrupt lung function and damage lung tissue, which, over time, can reduce vital lung capacity. On the other hand, regular physical activity has been proven to enhance lung capacity. However, there is still a lack of research specifically comparing the vital lung capacity between physically active male smokers and non-smokers. This study aimed to determine the differences in vital lung capacity between physically active male smokers and non-smokers. The study involved 50 male university students aged 20–23 who regularly exercised twice weekly. Subjects were divided into 25 smokers and 25 non-smokers with similar morphological characteristics. Vital lung capacity was measured using a digital spirometer connected to a computer. The results showed that the non-smoker group had a significantly larger vital lung capacity than the smoker group, with an average difference of 0.41 liters (p<0.05). These findings indicate that although both groups were physically active, smoking habits still negatively impacted vital lung capacity. Although the difference may not be fatal from a physiological standpoint, it can potentially affect sports performance, particularly in disciplines that rely heavily on respiratory capacity, such as aerobic-based sports and freediving.

Abstract

Indonesia has tropical climate characteristics, so it requires a cooling device where the utilization can be used as a room cooler and storage. Cooling machines generally use refrigerant working fluid in the compressor, refrigerant is a gas that is not environmentally friendly. So it is necessary to conduct alternative studies, that can replace refrigerant gas and simplify dimensions, weight, and convenience. This study was conducted to analyze the effect of applying a power supply on the performance of thermoelectric coolers. The experimental method applied 2 types of power supplies for thermoelectric Peltier coolers in cooling the mini cooler box space, then the 1400 ml capacity cooling room was given a varying volume of drinks. Analysis of the effect of using a power supply on the cooling performance of the mini cooler box on the thermoelectric Peltier system obtained the results that the time to reach the ambient temperature takes different times. The greater the load put into the box, the longer it takes to cool the drinking water. The greater the power supply ampere specifications, the better it is in accelerating the cooling rate but the power required is greater such as the application of the type of power supply with the type 20A.

Abstract

Background: Game-based learning (GBL) is widely used in physical education to enhance student motivation and fundamental motor skills (FMS). However, evidence from elementary school contexts, particularly using quasi-experimental designs with intact classes, remains limited.  Objectives: This study examined the effects of a 12-week game-based learning intervention on motivation and fundamental motor skills among elementary school students. Methods: A quasi-experimental one-group pretest–posttest design was employed involving 34 elementary school students selected through purposive sampling. The 12-week intervention consisted of weekly 105-minute sessions of dexterity-based game learning. Motivation was measured using a validated questionnaire, while fundamental motor skills were assessed through an age-appropriate motor skills test. Data were analyzed using descriptive statistics, normality and homogeneity tests, and paired-sample t-tests, with Cohen’s d calculated to estimate effect size. Finding/Results: The experimental group demonstrated significant increases in motivation and FMS from the pre-test to the post-test (p < 0.05). Although the effect size was small to medium, the observed increases reflect short-term positive changes following the intervention. Conclusion: The 12-week GBL intervention effectively enhanced motivation and FMS among elementary school students. While the findings support the use of GBL in physical education, the absence of a control group and potential class-level confounders limit causal interpretation. Future studies should employ randomized or controlled designs and include broader measures of engagement and motor competence.
