Chronic liver disease is a significant health problem and places a significant burden on healthcare services. Deaths from complications of chronic liver disease (cirrhosis and cancer) account for approximately 3.5% of all deaths worldwide each year. Hepatocellular carcinoma (HCC) is a primary liver tumor, accounting for 90% of all liver tumors. Due to limitations in liver transplantation, liver resection is considered the treatment of choice for HCC patients with a single tumor and sufficient liver function reserve. Liver resection and transplantation are the only curative treatment options available for HCC patients. Surgical procedures require anesthesia. General anesthesia is the preferred method for liver tumor resection. There are five main classes of anesthetic agents: intravenous (IV) anesthetics, inhalational anesthetics, IV sedatives, synthetic opioids, and neuromuscular blocking agents. Estimated health risks depend on the extent or severity of liver disease, the nature and timing of surgery, the type of anesthesia, and other comorbidities.

In this study, a device was designed and implemented to control the water pH and nutrient density (concentration) in a hydroponic system using the Mamdani method of fuzzy logic, thus maintaining nutrient solution parameters within an optimal range for plant growth. This system relies on three input values ​​obtained from a water pH sensor, a nutrient TDS sensor, and a flow meter. These three sensors are used to control four peristaltic motors, each of which functions to increase and decrease the pH and nutrient levels in the solution. The speed of the peristaltic pump motor, when the water pH is set at 6.5 and the nutrient concentration is set at 700 ppm, is influenced by the difference between the sensor reading and the set point. The greater the difference, the higher the peristaltic pump motor speed. Conversely, the smaller the difference between the sensor reading and the set point, the lower the peristaltic pump motor speed. Furthermore, the amount of water flowing through the pipe also influences the peristaltic pump motor speed.

This study critically examines the emerging phenomenon of celebrity preachers as a significant form of religious commodification within the realm of digital da’wah. The rapid proliferation of social media has fundamentally transformed how religious messages are disseminated, with platforms like YouTube, Instagram, and TikTok becoming primary channels. Utilizing a quantitative methodology that combines comprehensive literature studies with online questionnaires distributed to social media users, this research investigates public perceptions regarding digital da’wah practices and high-profile preachers. The findings reveal a commodification process characterized by three key aspects: the tailoring of content to suit market preferences, the shift of audiences into active consumers, and the strategic construction of public images by preachers to sustain popularity. While respondents value the accessibility of digital da’wah, they strongly emphasize the necessity of ethical boundaries to preserve its spiritual essence. Consequently, digital da’wah requires sincerity, scholarly integrity, and moral responsibility to remain an authentic medium for Islamic teachings.

This study aims to analyze various obstacles in Social Sciences (IPS) learning related to global issues that are increasingly influenced by technological advances, through literature study methods. Social studies has a strategic role in shaping students' understanding of social, economic, cultural, and political aspects, as well as fostering global awareness in the digital era. However, the effectiveness of social studies learning still faces a number of obstacles, especially low student interest because the material is considered boring, too theoretical, and less interesting than digital entertainment. In addition, less interactive learning methods, limited facilities, unconducive classroom environment, and lack of parental support also worsen the quality of learning. Through a comprehensive literature review, this study identifies several relevant learning strategies to overcome these constraints, including ProjectBased Learning, technology integration, and contextual approaches. These three strategies allow students to learn actively, critically, and collaboratively by relating social studies materials to global issues and real phenomena. This research provides theoretical contributions to the development of social studies learning models that are adaptive to technological developments, as well as practical benefits for teachers, schools, and policymakers in creating social studies learning that is more interesting, meaningful, and relevant to the global challenges of the 21st century.

This study aims to analyze the quality control of car tire production at Company X using the Statistical Process Control (SPC) method. The data used in this research are secondary data obtained from GitHub, consisting of weekly production and defect data observed over one year with a total of 52 observations. The analysis was carried out using descriptive statistics, histograms, P-charts, and cause-and-effect (Ishikawa) diagrams. The histogram results indicate that the distribution of defects is right-skewed, showing that most defects occur at a moderate level, although several extreme values are present. The initial P-chart analysis revealed several points below the lower control limit, indicating the presence of special cause variation and suggesting that the production process was not fully stable. After removing out-of-control data and recalculating the control limits, the revised P-chart showed that all data points were within the control limits, indicating that the production process was statistically under control. Furthermore, the Ishikawa diagram identified potential causes of defects related to human factors, machines, methods, materials, and the working environment. Overall, the results demonstrate that SPC is an effective tool for monitoring production stability and providing a systematic basis for improving quality consistency in car tire manufacturing processes.

The increasing consumption of packaged food products in Indonesia reflects modern lifestyle changes but simultaneously raises public health concerns related to high calorie, sugar, and fat intake. Nutritional information presented on food labels consists of multiple interrelated variables, making it difficult to identify dominant nutritional factors that characterize packaged food products. This study aims to apply Principal Component Analysis (PCA) to reduce the dimensionality of nutritional data and to map the nutritional characteristics of packaged food products in Indonesia. The research employs a quantitative exploratory approach using secondary data obtained from nutrition facts labels of 1,651 packaged food products. Seven nutritional variables were initially analyzed, namely total energy, protein, total fat, total carbohydrates, sugar, sodium, and dietary fiber. Data preprocessing included data cleaning, Z-score standardization, and iterative variable selection based on the Kaiser-Meyer-Olkin (KMO) measure and Bartlett’s Test of Sphericity to ensure sampling adequacy and sufficient correlation among variables. Variables with low sampling adequacy and perfect multicollinearity were eliminated, resulting in five variables retained for the final PCA model. Principal components were extracted using the eigenvalue greater than one criterion and confirmed through a scree plot, followed by Varimax rotation to enhance interpretability. The results indicate the formation of two principal components explaining approximately 69.7% of the total variance. The first component represents energy density and macronutrient richness, while the second component reflects carbohydrate-related characteristics, particularly the contrasting pattern between sugar and dietary fiber. Biplot visualization further illustrates product distribution based on these components. The findings demonstrate that PCA effectively simplifies complex nutritional information and provides a clear nutritional mapping of packaged food products, offering practical insights for consumers, producers, and policymakers in supporting healthier food choices in Indonesia.
