The physical work environment in the Aerosol Production Department of PT XYZ experienced problems related to excessive room temperatures reaching 37.3°C and chemical odor pollution caused by vapor recirculation from the coating oven process. These conditions potentially reduced operator comfort and concentration. This study aimed to analyze the effectiveness of the Kaizen approach through the Plan-Do-Check-Act (PDCA) cycle in controlling production room temperature and improving air quality. A quantitative descriptive method with an Action Research approach was employed. Problem identification and root cause analysis were conducted using the 7 QC Tools, particularly the Pareto Diagram and Fishbone Diagram. Improvement actions included the installation of turbine ventilators, aluminum foil roof insulation, and a 3-meter vertical exhaust ducting system. The results showed that the average room temperature decreased from 34.6°C to 27.4°C, representing a reduction of 7.2°C, while the peak daytime temperature decreased by 8.7°C and met the established threshold limit value. In addition, chemical odor pollution was completely eliminated. Therefore, the Kaizen-PDCA approach proved effective in improving the physical work environment sustainably.

This study aims to analyze the effect of homework load and extended study hours on students’ learning stress levels. The background of this research is based on increasing academic demands that may affect students’ psychological conditions. This study employs a qualitative approach with data collected through observation and interviews. The results indicate that excessive homework load and prolonged study duration significantly contribute to higher levels of learning stress. Students tend to experience physical and mental fatigue, decreased motivation, and difficulty managing time between study and rest. In addition, pressure to achieve high academic performance further exacerbates stress levels. Other factors such as lack of environmental support and less varied teaching methods also influence students’ stress. Furthermore, students often report feelings of anxiety and emotional exhaustion when academic tasks accumulate without adequate rest periods. This condition not only affects their psychological well-being but also reduces concentration and learning effectiveness in the classroom. Therefore, balanced learning load management, appropriate task distribution, and more effective and humanistic teaching strategies are needed to reduce learning stress and improve the quality of education. Schools and educators are encouraged to consider students’ cognitive capacity and mental health in designing assignments and study schedules to create a more supportive learning environment.

This study aims to analyze the internalization of Islamic developmental psychology values through the Qur'an memorization (Tahfidz Al-Qur'an) program in shaping the character of middle adolescents aged 13–17 years in the digital era at Al Hayya Orphanage Foundation, Depok. Adolescence is a transitional stage characterized by significant physical, emotional, social, and spiritual changes. In the digital era, adolescents face various challenges, such as social media addiction, cyberbullying, declining social interaction, and moral degradation, all of which may affect character development. Therefore, strengthening character education based on Islamic values has become increasingly important. This research employed a qualitative approach using a case study method to gain an in-depth understanding of the phenomenon under investigation. Data were collected through observation, in-depth interviews, and documentation involving orphanage caregivers, Tahfidz instructors, and students at Al Hayya Orphanage Foundation, Depok. The findings indicate that the Tahfidz program plays a positive role in character formation through habituation, role modeling, spiritual guidance, and a supportive religious environment. From the cognitive perspective, students demonstrated improvements in discipline, concentration, responsibility, and self-regulation. Emotionally, they became more patient, better able to control their emotions, and experienced inner peace through intensive engagement with the Qur'an. Socially, the program fostered attitudes of mutual assistance, respect, empathy, and stronger social relationships among students.This study reveals that the Tahfidz program serves not only as a means of memorizing the Qur'an but also as an effective medium for internalizing the values of Islamic developmental psychology and fostering Qur'anic character among adolescents in facing the challenges of the digital era.  

The purpose of this study was to analyze the implementation of Al-Qur’an and Hadith teaching at MAN 2 Karawang, including the challenges faced and approaches to resolving them.

Antibacterial activity was tested using the disc diffusion method on Mueller Hinton Agar media. Data were analyzed using the Kruskal-Wallis and Mann-Whitney tests. The results showed that water hyacinth extract inhibited the growth of Streptococcus mutans. The largest inhibition zone was observed at 50% concentration, while the smallest was found at 6.25% concentration. Kruskal-Wallis analysis showed significant differences among groups (p<0.05). In conclusion, water hyacinth (Eichhornia crassipes) extract has antibacterial activity against Streptococcus mutans.

Cutaneous fungal infections caused by Malassezia furfur remain a significant health concern in tropical regions, highlighting the need for safe and effective alternative therapies. Moringa oleifera L. leaves are reported to contain various secondary metabolites, including flavonoids, tannins, and saponins, which exhibit potential antifungal activity. This study aimed to develop a topical suspension formulation of Moringa oleifera leaf extract and to evaluate the effect of varying extract concentrations on the physical characteristics of the preparation. An experimental method was employed using four formulations: F0 as the control, and F1, F2, and F3 containing 9%, 10%, and 11% extract, respectively. Evaluation parameters included organoleptic properties, homogeneity, pH, viscosity, and adhesiveness, as well as stability testing using a cycling test method for 12 days. The results demonstrated that all formulations exhibited good organoleptic characteristics, homogeneity, and viscosity. The pH values remained within the acceptable range for skin preparations, although slight fluctuations were observed during storage. Adhesiveness also showed variations across several testing cycles. Overall, the formulations met acceptable physical quality criteria and demonstrated potential for further development as topical suspensions; however, formulation optimization is still required to enhance stability during storage.

Background: Acne vulgaris is one of the most common skin problems and is closely associated with the activity of Propionibacterium acnes. Long-term use of antibiotics may lead to bacterial resistance; therefore, alternative antibacterial agents derived from natural products are needed. White rice (Oryza sativa L.) is known to contain bioactive compounds such as flavonoids, alkaloids, terpenoids, tannins, and saponins, which potentially exhibit antibacterial activity. Objective: This study aimed to evaluate the antibacterial activity of ethanol extract of white rice against the growth of Propionibacterium acnes. Methods: This research was conducted as a laboratory experimental study using a post-test only control group design. The ethanol extract of white rice was prepared by maceration using 70% ethanol. Antibacterial activity was evaluated using the disc diffusion method with extract concentrations of 100%, 50%, 25%, 12.5%, and 6.25%. Clindamycin was used as a positive control, while sterile distilled water served as a negative control. The parameter observed was the diameter of the inhibition zone. Result: The results of phytochemical screening showed that the ethanol extract of white rice (Oryza sativa L.) contains flavonoids, alkaloids, and terpenoids. Antibacterial activity test showed that the ethanol extract of white rice at concentrations of 100%, 50%, and 25% was able to inhibit the growth of Propionibacterium acnes by forming an inhibition zone, while at concentrations of 12.5% and 6.25% no inhibition zone was formed. The highest inhibition zone diameter was found at a concentration of 100%. The ethanol extract of white rice at concentrations of 100% (7.65 mm), 50% (6.77 mm), and 25% (6.15 mm) was able to inhibit the growth of Propionibacterium acnes, and was classified as having moderate inhibition. In contrast, at concentrations of 12.5% and 6.25%, the ethanol extract of white rice did not show any inhibitory activity detected in vitro using the disc diffusion method. The results of statistical analysis showed a p value <0.001, which means there was a significant difference in the diameter of the inhibition zone between the treatment groups. Conclusion: In conclusion, the ethanol extract of white rice exhibits antibacterial activity against Propionibacterium acnes in a concentration-dependent manner; however, its inhibitory effect remains lower than that of clindamycin.

Antimicrobial resistance is a persistent threat to hospital care, particularly when empirical therapy relies on broad-spectrum antibiotics without continuous evaluation of local use and susceptibility patterns. This literature review aimed to synthesize evidence from four Indonesian hospital-based studies regarding antibiotic utilization, rationality assessment, and bacterial resistance profiles. A structured narrative review was conducted using four selected articles provided by the author. Data were extracted for study design, setting, population, antibiotic evaluation method, dominant antibiotic classes, rationality indicators, resistance profile, and stewardship implications. The four studies were descriptive and hospital-based, using retrospective records, concurrent observation, ATC/DDD with DU 90%, qualitative rationality criteria, and antibiogram data. The synthesis showed a consistent concentration of antibiotic use in broad-spectrum groups, especially third-generation cephalosporins, penicillins, quinolones, and macrolides. In a Bandung public hospital, total antibiotic consumption reached 95,719.01 DDD, with penicillins, cephalosporins, quinolones, macrolides, and sulfonamides included in the DU 90% segment. In intensive care, ceftriaxone was the most frequently used antibiotic and most rationality indicators were appropriate, although clinically significant drug interactions were still identified. In pediatric acute respiratory infection inpatients, cefotaxime and ceftriaxone dominated empirical therapy. Resistance mapping in Denpasar highlighted relevant Gram-positive and Gram-negative pathogens and recommended antibiotics according to susceptibility levels. Overall, the reviewed evidence supports an integrated antimicrobial stewardship model combining ATC/DDD-DU 90% surveillance, qualitative rationality evaluation, antibiogram-based empirical guidance, and periodic feedback to prescribers.

This study discusses a student concentration detection system using Convolutional Neural Network (CNN) with the MobileNetV2 architecture. The dataset was adapted from Classroom Student Behaviors and mapped into four concentration categories: highly focused, focused, less focused, and unfocused. The system was tested with a 720p webcam and produced real-time detection data. The evaluation results show an overall accuracy of 75.85%, with the highest precision achieved in the focused class (0.9859) and the highest recall in the highly focused (0.9739) and unfocused (0.9811) classes. The confusion matrix indicates that the focused class was detected most consistently, while highly focused and unfocused classes were often misclassified as focused, resulting in lower precision. In real-time testing, the system operated at an average of 7 FPS and worked optimally when students faced the camera directly with sufficient lighting, but its performance decreased significantly at face angles greater than 45°. User evaluation shows that 75% of students rated the detection results as accurate/very accurate with an average satisfaction score of 3.6 out of 5, and 75% felt assisted in recognizing their concentration level. From the teachers’ perspective, most stated that the results were consistent with classroom observations, and all expressed willingness to reuse the system.

Food safety of fresh fish is an important concern because fish is highly perishable and may be misused with hazardous preservatives such as formalin. This study aimed to determine formalin content and analyze the relationship between length and weight of Nile tilapia (Oreochromis niloticus) and formalin levels in traditional markets of Gorontalo City. The study was conducted from January to February 2026 in five traditional markets, namely TPI Tenda, Moodu, Potanga, Andalas, and Sentral. Nile tilapia samples were analyzed using a formaldehyde test kit, and formalin levels were expressed in ppm. Total length and fish weight were measured, and the relationship between physical size and formalin content was analyzed using Pearson correlation. The results showed that all Nile tilapia samples tested positive for formalin, with concentrations ranging from 0.11 to 0.23 ppm. The highest formalin levels were found in TPI Tenda and Moodu, each at 0.23 ppm, while the lowest level was found in Sentral at 0.11 ppm. Fish length ranged from 19.43 to 25.61 cm, while fish weight ranged from 0.17 to 1.78 g. The correlations between length and formalin content and between weight and formalin content were both very strongly negative, with r = -0.97. These findings indicate that smaller fish tended to contain higher formalin levels. Market supervision, trader education, and formalin-free fish handling practices should be strengthened to protect consumer health.

Rapid developments in digital technology have had a significant impact on students’ lives, particularly in the use of social media and excessive consumption of digital content. The phenomenon known as Brain rot has become a growing concern because it can affect students’ concentration, learning motivation, and quality of thinking. This study aims to provide education regarding the impact of brain rot on students’ concentration and learning motivation in the digital era. The activities were carried out through counseling methods, interactive discussions, and mentoring for junior high school students. The materials presented included the definition of brain rot, the effects of excessive digital media use, the importance of learning time management, and strategies to improve learning focus. The results of the activity showed that students gained a better understanding of the negative impacts of uncontrolled digital media use. In addition, students began to realize the importance of limiting gadget use and increasing productive learning activities. This educational program also helped raise students’ awareness of the importance of maintaining mental health and cognitive abilities amid the rapid development of digital technology. Through this educational activity, students are expected to use technology wisely so that their concentration and learning motivation can improve optimally. Educational programs regarding brain rot need to be carried out continuously as part of strengthening digital literacy within the school environment.

Diabetes mellitus, as a persistent non-infectious metabolic pathology increasingly prominent in the global epidemiological spectrum, is fundamentally characterized by dysfunctional hyperglycemia rooted in primary disruptions of pancreatic insulin hormone synthesis or peripheral resistance to its biological action, thereby inducing dynamic imbalances in gluconeogenesis and glycolysis pathways; amid the hypothesis that body mass index (BMI) as a measure of central adiposity potentially mediates variability in serum glucose levels, this quantitative observational study with a cross-sectional design rigorously tests the causal relationship between BMI and fasting/random blood glucose concentrations in a cohort of 134 adult subjects with type 2 diabetes mellitus affiliated with primary care services at Puskesmas Bongo II, Boalemo Regency, through an inclusive total sampling recruitment strategy, precision anthropometric measurement instruments (height, weight, WHO BMI categorization), and laboratory-validated glucometric validation, with multivariate inferential processing based on the Chi-Square independence test at a Type I error rate of α=0.05 using the latest edition of the SPSS analytical suite; the demographic profile highlights female gender supremacy (90 individuals, 67.2%), the normoweight group (78 cases, 58.2%), concurrent with substantial glycemic elevation prevalence (78 subjects, 58.2%), but the crucial statistical output reveals a p-value of 0.831 (>0.05) that negates any probabilistically meaningful association, thus the substantive conclusion affirms the non-significance of the BMI-glucose relationship in this local context, while implying the dominance of alternative etiopathogenic factors such as hypercaloric macronutrient intake patterns, deficits in aerobic/anaerobic physical activity, non-adherence to multidisciplinary pharmacological protocols (e.g., metformin/oral hypoglycemics), and a comprehensive management paradigm integrating behavioral education, continuous monitoring, and personalized interventions to mitigate long-term cardiovascular risks across the diabetes mellitus spectrum.

Children with intellectual disabilities experience limitations in intellectual functioning and adaptive abilities, which impact their independence in daily activities, including buttoning clothes. This skill requires fine motor coordination, concentration, and a proper understanding of task sequences. This case study aims to determine the effectiveness of button board play therapy in improving fine motor skills in children with intellectual disabilities. The method used was descriptive with a case study approach involving two children with moderate intellectual disabilities aged 8 and 9 years at SLB Bhakti Luhur Maumere. Data were collected through interviews, observations, and documentation. The intervention consisted of button board play therapy conducted for 6 days, with a duration of 15–30 minutes per day, implemented gradually and repeatedly. The results showed that before the intervention, both children were unable to button their clothes independently. After the intervention, there was an improvement in their ability, as the children began to button some buttons (2–3 buttons) with better motor coordination, although they still required assistance and supervision. In conclusion, button board play therapy is effective in gradually improving fine motor skills and independence in children with intellectual disabilities. It is recommended that the intervention be carried out consistently and involve parents to achieve optimal results.

The Free Nutritious Meal Program (MBG) is one of the government’s strategic policies aimed at improving students’ nutritional status and learning quality, particularly at the junior high school level.

The consumption of sugar-sweetened beverages (SSBs) in Indonesia continues to increase and is associated with the risk of obesity, diabetes, and cardiovascular diseases due to oxidative stress. Kombucha has potential as a functional antioxidant beverage; however, its use is still dominated by Camellia sinensis, limiting the utilization of local ingredients. Bilimbi leaves (Averrhoa bilimbi Linn.) have high antioxidant activity and potential as an alternative substrate. This study aimed to analyze the effect of fermentation time variations (4, 7, and 14 days) and sugar concentrations (10% and 15%) on the acceptability and antioxidant activity of bilimbi leaf kombucha, as well as to determine the best formulation. The study used a true experimental design with a Completely Randomized Design (CRD) involving six formulations (F1–F6) and one control (F0). Antioxidant activity was analyzed using the DPPH method. The results showed that fermentation time and sugar concentration significantly affected antioxidant activity.). The highest antioxidant activity was found in F2 (IC50 98.67 ppm, strong category). F2 was determined as the best formulation due to its  antioxidant activity. F2 has the potential to be developed as an alternative functional beverage to reduce SSB consumption. Further research is recommended to conduct stability testing and in vivo studies.

Irregular sleep patterns are a common issue experienced by university students and are often considered a normal part of academic life. However, such conditions can have negative effects on students’ learning concentration and cognitive function. Poor sleep patterns are generally influenced by various factors, including high academic workload, habitual late-night activities, poor time management, and excessive use of electronic devices at night. This study aims to examine the relationship between sleep patterns and students’ learning concentration, identify factors contributing to irregular sleep patterns, and analyze constraints as well as propose solutions to improve sleep quality in order to enhance learning concentration. The method used in this scientific paper is a literature review, which involves examining relevant scientific sources such as research journals and academic literature related to sleep patterns and students’ learning concentration. The results of the review indicate that students with poor sleep patterns tend to experience physical fatigue, decreased immune function, cognitive impairment, and difficulties in maintaining focus and concentration during the learning process. In the long term, these conditions have the potential to reduce academic achievement and learning motivation. Therefore, it can be concluded that effective time management, limiting the use of electronic devices before bedtime, creating a conducive sleep environment, and support from universities through health education play an important role in improving students’ sleep patterns. With regular and high-quality sleep, students’ learning concentration is expected to improve, allowing the learning process and academic achievement to proceed optimally.
