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 impact of nickel mining activities on the religious life of the community in West Kabaena District, Bombana Regency. The research employed a qualitative method with a descriptive approach to obtain an in-depth understanding of the social and religious changes occurring within the community. Data were collected through interviews, observations, and documentation involving religious leaders, community leaders, youth representatives, and mining workers. The collected data were analyzed through data reduction, data display, and conclusion drawing. The findings indicate that nickel mining activities have not diminished the community’s understanding of environmental stewardship as a religious responsibility. However, increasing economic dependence on the mining sector has gradually reduced public concern for environmental preservation. In the religious sphere, mining activities have contributed positively by supporting the construction and improvement of worship facilities and religious programs. Nevertheless, work-related demands have reduced the participation of some community members in religious activities. Furthermore, mining activities have affected social solidarity within the community. Values such as brotherhood, mutual cooperation, and social care remain preserved, although changes in social interaction patterns and widening economic disparities have become increasingly apparent. The study concludes that nickel mining activities generate both positive and negative impacts on the religious life of the West Kabaena community. Therefore, balanced policies integrating economic development, environmental sustainability, and religious values are essential to promote sustainable community welfare and strengthen social harmony.

This study aimed to analyze the influence of workload and burnout on nurses’ sleep quality while controlling for age, gender, and education as potential confounding variables. A quantitative analytic study with a cross-sectional design was conducted among 156 nurses working in a private hospital in Depok City. Data were collected using a workload questionnaire, the Maslach Burnout Inventory (MBI), and the Pittsburgh Sleep Quality Index (PSQI). The data were analyzed using Chi-Square tests and multiple logistic regression. The findings showed that both workload and burnout had significant effects on sleep quality (p < 0.05), with burnout identified as the most dominant factor. Age and gender were also significantly associated with sleep quality, whereas education did not show a statistically significant effect. The regression model demonstrated excellent fit, indicated by a McFadden pseudo R² value of 0.908. These results suggest that occupational factors, particularly burnout, play an important role in determining nurses’ sleep quality. Therefore, effective stress reduction and workload management strategies are needed to support nurses’ well-being and improve sleep quality.

This study aims to examine the effectiveness of implementing forgiveness therapy in enhancing the personal growth of inmates at the Tangerang Class II-A Women’s Correctional Facility. The method used was a pre-experimental study with a one-group pretest-posttest design. Nine subjects aged 20-40 years were selected from 50 inmates based on low to moderate scores on the forgiveness scale and the psychological well-being scale. The intervention consisted of six sessions adapted from the forgiveness model developed by Enright and Fitzgibbons. Data analysis utilized a paired-sample t-test and the N-Gain formula. The results showed a significant increase in personal growth scores from the pretest (M = 7.00; SD = 1.225) to the posttest (M = 9.44; SD = 1.424), with t(8) = −8.315 and p < 0.001. An N-Gain value of 0.610 indicates moderate effectiveness. The follow-up measurement (M = 9.67; SD = 1.118) did not differ significantly from the post-test (p = 0.347), indicating the sustainability of the changes achieved. Forgiveness scores also increased from 65.33 (pre-test) to 86.67 (post-test) and 87.33 (follow-up), confirming the role of forgiveness as a psychological mechanism for personal growth. These findings support the integration of structured forgiveness therapy into correctional programs for women’s prisons.

The risk of accidents in the school environment is quite high, but the ability of the School Health Business Team (UKS) to handle emergencies is often still limited to theoretical knowledge without adequate practical skills. This study aims to analyze the influence of the Role Playing and Emergency Simulation (RANGGA) method on the improvement of the knowledge and skills of the UKS Team in junior high school. This study used a quasi-experiment design with a pre-post test with control group design. The research sample amounted to 60 respondents which were taken by purposive sampling technique. The intervention group was given RANGGA training, while the control group was given conventional education. The data were analyzed using the non-parametric Wilcoxon Signed Ranks Test because the data distribution was abnormal. In the intervention group, there was an increase in the average knowledge score from 88.7 to 97.9 and the skill score from 87.99 to 97.98. The results of the Wilcoxon test showed a significance value of p<0.001 for both variables in the intervention group, indicating a very strong influence of the RANGGA method. In contrast, although the control group experienced an improvement, the variation in scores remained higher and the improvement was not as significant as the intervention group. The RANGGA method is significantly effective in improving the emergency competence of the UKS Team through an experiential learning approach. It is recommended for school institutions to integrate simulation and role play methods in the UKS training curriculum to ensure optimal emergency response readiness.

Due to its effect on the caliber of generations to come, iron deficiency anemia in teenage females is one of Indonesia's most pressing reproductive health concerns. Adolescents' awareness to autonomously adopt preventative actions is shaped mostly by their knowledge. The purpose of this research is to determine whether there is a correlation between the prevalence of anemia among teenage females in Boyolali Regency and their degree of education. Using a cross-sectional design, this study employs quantitative correlational analytic methods. An accidental sampling approach was used to obtain a sample size of 80 respondents from the population of seventh grade female pupils. A digital POCT device was utilized to quantify the incidence of anemia variables based on hemoglobin (Hb) levels, while a structured questionnaire instrument was employed to gather data for knowledge variables. The Chi-Square test was used to assess the bivariate data analysis. According to the univariate analysis, 62.5% of the participants (50 respondents) had a decent level of knowledge, and 73.8% of the participants (59 respondents) did not suffer from anemia (Hb > 12 g/dL). With a p-value of 0.000 (p < 0.05), the results of the bivariate test were generated. Anemia is more common among female students at MTs Al Ihsan Doglo who have a higher degree of expertise, according to this study. School districts should keep an eye on students' iron pill use and improve their nutrition education programs.

Diesel engines are widely used in the transportation and industrial sectors due to their high thermal efficiency and good operational durability. However, increased fuel consumption due to inefficiency of the injection system remains a common problem. Injector characteristics, particularly nozzle diameter and injection pressure, are important factors that affect the quality of fuel atomization, air-fuel mixing, and combustion efficiency. An inappropriate combination of parameters can cause suboptimal combustion and increase fuel consumption. This study aims to analyze the effect of variations in nozzle diameter and injection pressure on fuel consumption efficiency in diesel engines. The method used is an experiment with variations in nozzle diameter of 0.150 mm, 0.152 mm, and 0.154 mm and injection pressures of 400 bar, 420 bar, and 440 bar. Tests were conducted at engine speeds of 500 rpm, 1000 rpm, and 1500 rpm with a fuel consumption measurement time of one minute for each parameter combination. Fuel consumption was measured using the volumetric method and analyzed through the fuel volumetric flow rate, fuel mass flow rate, Brake Power (BP), and Brake Specific Fuel Consumption (BSFC). The results showed that the combination of a nozzle diameter of 0.150 mm and an injection pressure of 400 bar produced the lowest BSFC value, thus providing the best fuel consumption efficiency. Meanwhile, the combination of a nozzle diameter of 0.152 mm and an injection pressure of 420 bar showed the closest condition to optimal because it was able to provide a balance between atomization quality and the amount of fuel injected, resulting in efficient and stable combustion. Thus, the efficiency of a diesel engine is influenced by the balance of nozzle size and injection pressure, not solely by the lowest fuel consumption.

ASTM A36 steel has relatively low hardness and corrosion resistance, making surface treatment necessary to improve its material properties. This study aims to determine the effect of temperature and holding time variations in the pack carburizing process on the hardness, corrosion rate, and microstructure of ASTM A36 steel.

Hardness testing was conducted using the Rockwell B scale (HRB) method, corrosion rate testing was performed according to the ASTM G31 method, and microstructural observations were carried out using Scanning Electron Microscopy (SEM). The results showed that increasing the temperature and holding time improved the hardness and corrosion resistance of ASTM A36 steel. The highest hardness value was obtained at a temperature of 950°C with a holding time of 60 minutes, reaching 114.1 HRB. Microstructural analysis revealed the formation of a martensitic phase on the specimen surface after the carburizing process.

Type 2 diabetes mellitus is a chronic metabolic disease characterized by hyperglycemia due to impaired insulin secretion, insulin resistance, or a combination of both. HbA1c levels are used as an indicator of long-term glycemic control in patients with type 2 diabetes mellitus. Insulin therapy is one of the treatment options given to help achieve glycemic control targets. The purpose of this study was to determine the difference in HbA1c levels of type 2 diabetes mellitus patients with insulin and non-insulin therapy at PKU Muhammadiyah Gamping Hospital. This research method used a descriptive study with a cross-sectional approach. The subjects in this study were 80 type 2 diabetes mellitus patients who had used insulin and non-insulin therapy for less than 1 year, using Purposive Sampling techniques and data analysis using SPSS with Chi-Square and Mann-Whitney tests. This study has obtained ethical approval from PKU Muhammadiyah Gamping Hospital. This study shows that the characteristics of gender and age of type 2 DM patients with insulin and non-insulin therapy are dominated by women at 60.0% and 43.3%, while elderly patients at 60.0% and 53.3%. Of the 50 patients using insulin, 45 patients (90.0%) had controlled HbA1c and 5 patients (10.0%) were uncontrolled. Meanwhile, all non-insulin patients, 30 patients (100%), had uncontrolled HbA1c. Based on this study, there is a significant difference in HbA1c levels between type 2 diabetes mellitus patients with insulin and non-insulin therapy with a p-value <0.001. Patients using insulin therapy tend to have better glycemic control than patients not using insulin therapy.

Collaboration between classroom teachers and Islamic Religious Education (PAI) teachers constitutes an essential strategy for instilling religious moderation values in elementary schools. This study aims to: (1) describe the forms of collaboration developed between classroom teachers and PAI teachers; (2) assess the effectiveness of such collaboration in inculcating religious moderation values; (3) identify changes in students' attitudes as tangible outcomes of collaboration; and (4) analyze supporting and inhibiting factors of collaboration at SDN 3 Wanamekar. A descriptive qualitative approach was applied using field study methods. Data were gathered through in-depth interviews, participatory observation, and document review. Data analysis followed the interactive model of Miles, Huberman, and Saldana, encompassing data condensation, data display, and conclusion drawing. Data credibility was ensured through source triangulation and technique triangulation. Findings indicate that collaboration occurs in two primary forms: reactive collaboration as a spontaneous response to students' intolerant behavior, and planned collaboration involving curriculum coordination, partial co-teaching, and joint evaluation. Collaboration was assessed as sufficiently effective yet suboptimal due to time constraints and excessive administrative burdens. Positive changes in students' tolerance and inclusive attitudes were identified as concrete outcomes. Supporting factors include favorable interpersonal communication, principal support, and moderation value integration in the Merdeka Curriculum. Main inhibiting factors are time limitations, administrative burdens, shallow conceptual understanding of religious moderation, and the absence of a standardized collaboration model. The study recommends establishing structured collaboration schedules and religious moderation training programs for all teachers.

The development of social media has significantly changed human communication patterns. On the one hand, digital media provides a space for freedom of expression, but on the other hand, it has also given rise to digital judgmental cultural phenomena such as Cancel culture and cyberbullying. These phenomena often give rise to verbal violence, public humiliation, and massive social exclusion in cyberspace. This article aims to analyze the phenomena of Cancel culture and cyberbullying from a Christian ethical perspective. The research method used is a literature review with a theological-ethical approach. The results of the study indicate that the digital judgmental culture contradicts the principles of love, respect for human dignity as the Imago Dei, and Christian communication ethics taught in the Bible. Christian ethics views every individual as having value before God, so the practices of humiliation, digital bullying, and public judgment are unjustifiable. The church and believers are called to present constructive, loving, communication in the digital space.

D Dowry (mahar) is an obligation of a groom to his bride in Islamic marriage, symbolizing respect and responsibility. In the Buton community, mahar also develops as a customary tradition known as boka, which carries both symbolic and socio-cultural meanings. This study aims to analyze the concept of mahar according to the Shafi’i school of law and its implementation in Taduasa Village, South Buton Regency. This research uses a qualitative method with data collection techniques including interviews, documentation, and literature review. The findings show that mahar is viewed as a symbol of respect for women and is determined based on lineage and social status. According to the Shafi’i school, such practices are permissible as long as they are based on mutual agreement and do not burden the groom. However, excessively high dowry amounts in some cases may hinder marriage. This study concludes that the mahar tradition in Taduasa Village remains consistent with Shafi’i principles but should be adjusted to the Islamic values of ease and public welfare.
