This study aims to analyze the effect of cutting parameters on surface roughness in the turning process of AISI 1045 steel. The investigated parameters include cutting speed, feed rate, and depth of cut. A quantitative approach was employed using multiple linear regression analysis with SPSS software. The dataset consisted of 30 simulated experimental observations with varying cutting parameter conditions. Prior to regression analysis, classical assumption tests including normality, multicollinearity, and heteroscedasticity tests were conducted to ensure the validity of the model. The results indicated that all assumptions were satisfied. The findings reveal that simultaneously, all independent variables have a significant effect on surface roughness with a coefficient of determination of 82.1%. Partially, Feed rate and cutting speed significantly influence surface roughness, while depth of cut does not show a significant effect. Feed rate is identified as the most dominant variable affecting surface roughness, where an increase in Feed rate leads to higher roughness values. In contrast, increasing cutting speed tends to reduce surface roughness. This study highlights the importance of controlling cutting parameters, particularly Feed rate and cutting speed, to improve machining quality. The results provide practical implications for manufacturing industries in optimizing machining parameters to achieve better surface quality and process efficiency.

This study aimsmto examineiin depthvthe perspective of information technology law and human rights on the phenomenon of political buzzers on social media within the context of digital development in the era of globalization. This research is motivated by the rapid advancement of information technology, which has brought significant changes in various aspects of society, including the political sphere that increasingly utilizes social media as a means of communication and information dissemination. The phenomenon of political buzzers has become a controversial issue, particularly during election periods, as it is often associated with the spread of inaccurate information, defamation, hate speech, and the manipulation of public opinion that may harm society and disrupt social stability. This study employs a normative legal research method using statutory and conceptual approaches. The results indicate that political buzzers generally operate under the justification of freedom of expression as part of human rights. However, such freedom is not absolute and must be limited to prevent violations of others' rights and to maintain public order. In this regard, information technology law in Indonesia, particularly through regulations governing digital activities, plays an important role in controlling deviant buzzer practices. Nevertheless, the absence of specific regulations explicitly governing political buzzers has resulted in less optimal law enforcement. Therefore, strengthening regulations and increasing public awareness in the wise use of social media are necessary to create a healthy, responsible, and sustainable digital ecosystem.

Anxiety disorders are common mental health problems among adolescents, particularly high school students who face academic demands, social pressure, and emotional changes. Family support, sleep quality, and academic stress are considered factors related to students’ anxiety levels. This study aimed to examine the relationship between family support, sleep quality, academic stress, and anxiety disorders among students of SMAN 1 Sumbawa Besar. An analytical study with a cross-sectional design was conducted involving 114 students selected through stratified random sampling. Data were collected using the Perceived Social Support–Family (PSS-Fa), Pittsburgh Sleep Quality Index (PSQI), Educational Stress Scale for Adolescence (ESSA), and Depression Anxiety Stress Scale (DASS-42). Bivariate analysis was performed using the chi-square test, while multivariate analysis employed binary logistic regression. Bivariate results indicated significant associations between family support, sleep quality, academic stress, and anxiety disorders (p < 0.05). However, multivariate analysis revealed that only family support and sleep quality were significantly associated with anxiety disorders, while academic stress was not significant after controlling for other variables. These findings suggest that anxiety prevention efforts should prioritize strengthening family support and improving sleep quality, alongside academic stress management within the school environment.

Air quality in the Special Capital Region of Jakarta has shown a concerning decline in recent years, largely due to high emissions from motor vehicles as the main source of pollution in urban areas. The Provincial Government of DKI Jakarta issued Governor Regulation Number 66 of 2020 concerning Exhaust Emission Testing for Motor Vehicles as a public policy instrument aimed at controlling air pollution. This study aims to analyze the implementation of the regulation from a public policy perspective and to identify supporting and inhibiting factors in its execution. The research employs a normative juridical method with statutory and conceptual approaches, supported by qualitative analysis of policy documents and reports on the implementation of emission testing. The results reveal that the implementation of the regulation has not been optimal due to limited emission testing infrastructure, low levels of public awareness and socialization, and inconsistent enforcement of administrative sanctions. Nevertheless, there are opportunities to improve policy effectiveness through strengthened inter-agency coordination, digitalization of monitoring systems, and increased environmental literacy among the public. Therefore, the success of emission control policy implementation is highly dependent on resource support, regulatory consistency, and community awareness, necessitating a comprehensive and continuous multi-stakeholder improvement strategy and stronger commitment.

This study was conducted at PT. Asmin Bara Bronang, Sepan Uring Village, Kapuas Tengah District, Kapuas Regency, Central Kalimantan Province, with the aim of analyzing the productivity and influencing factors of the PC 300 excavator in coal getting activities to support the achievement of production targets. The objective of this research is to analyze the actual productivity and the factors affecting it in Sector 7 coal getting operations. The research method used field observation with a quantitative descriptive analysis approach. The results show that the productivity of the PC 300 excavator ranges from 127.12 to 224.29 tons/hour, with an average of 173.98 tons/hour. In several conditions, the productivity is still below the company’s target of 180 tons/hour. The analysis indicates that productivity is influenced by material conditions, particularly the Hardgrove Grindability Index (HGI) value of 47, which reflects relatively harder material with coarser particle size, and a moisture content of 22.71%, causing the material to be sticky and cohesive, thereby affecting the bucket filling process. In addition, operational factors such as bottom loading patterns, limited number of tailgate dump trucks, and suboptimal selection of dump truck types also contribute to productivity performance.  Based on the findings, it can be concluded that the productivity of the PC 300 excavator has not consistently met the company’s target. Therefore, improvement efforts are required, including the implementation of top loading methods, increasing the number of tailgate dump trucks, optimizing the selection of hauling equipment, and controlling material conditions that affect the digging process.    

Hypertension is a non-communicable disease often referred to as a silent killer because it generally does not present noticeable symptoms. Several risk factors contribute to the development of hypertension, including high body mass index (BMI) and low levels of physical activity. However, data regarding the association between BMI, physical activity, and hypertension at Pakuan Baru Public Health Center, Jambi City, remain limited. Therefore, this study aimed to determine the relationship between body mass index and physical activity with hypertension among adults at Pakuan Baru Public Health Center, Jambi City. This study employed a quantitative approach with a cross-sectional design. The research was conducted at Pakuan Baru Public Health Center, Jambi City, from November 19 to December 6, 2025. The study population consisted of all adult patients with hypertension at Pakuan Baru Public Health Center, totaling 2,797 individuals. A sample of 93 respondents was selected using an accidental sampling technique. Data were collected using observation sheets through measurements of height and weight to calculate BMI, as well as the Global Physical Activity Questionnaire (GPAQ). Data analysis was performed using univariate and bivariate analyses with the chi-square statistical test. The univariate analysis showed that 27 respondents (29.0%) were classified as severely obese, 42 respondents (45.2%) had a low level of physical activity, and 28 respondents (30.1%) were categorized as having stage 2 hypertension at Pakuan Baru Public Health Center, Jambi City. The bivariate analysis revealed a significant relationship between body mass index and physical activity with blood pressure among patients with hypertension (p = 0.000). It is expected that healthcare providers at Pakuan Baru Public Health Center will continue to provide education regarding the importance of controlling body mass index and engaging in regular physical activity, as these factors contribute to increased blood pressure among patients with hypertension.
