In the learning process, there are various important aspects that must be considered, especially by teachers as transmitters of knowledge. The success of learning depends heavily on the teacher's ability to manage the classroom to create a safe, comfortable, and enjoyable learning atmosphere. Therefore, teachers need to choose the right learning method so that learning objectives can be achieved effectively. One method that can be used is Outdoor Learning, which is learning outside the classroom that provides opportunities for students to develop talents and creativity more broadly through direct experience in the open air. Management of the learning environment is also a crucial factor in supporting learning success. Several things that need to be considered include understanding the nature and development of student intelligence, getting to know students individually, utilizing student behavior in organizing learning, and developing critical thinking, creativity, and problem-solving skills. In addition, teachers need to create an attractive classroom, utilize the environment as a learning resource, provide constructive feedback, and differentiate between students' physical and mental activities. The learning environment itself consists of indoor and outdoor environments. The indoor environment includes school facilities such as classrooms, libraries, laboratories, and auditoriums. Meanwhile, the outdoor environment includes places outside the school that can be used as learning resources, such as museums, mosques, monuments, and fields. Prospective teachers need to understand the importance of managing the learning environment and understand the various types and benefits of learning environments to support an effective learning process.

Breast cancer is one of the types of cancer that has the highest incidence in women, with an increasing incidence at a young age. The aim of the study was to identify factors associated with the incidence of breast cancer in women under 40 years of age at RSUD Arifin Achmad Riau Province. This study used a case control design with a retrospective approach with a sample of 76. The sampling technique used was consecutive sampling. Data analysis was done with chi-square test. The results showed that the majority of respondents had high school education (55.3%) in the case group and (57.9%) in the control group, the average age of the case group was 36.05 and the control group was 33.58, the age of menarche (68.4%) in the case group and (28.9%) in the control group, breastfeeding history (47.4%) in the case group and (15.8) in the control group, hormonal contraception (13.2%) in the case group and (10.5%) in the control group, family history (44.7%) in the case group and (2.6%) in the control group. Bivariate analysis showed there was an association between menarche age factor (P = 0.001, OR = 5.318), breastfeeding history factor (P = 0.007, OR = 4.800), family history factor (P = 0.000, OR = 29.952) with the incidence of breast cancer. There was no association between hormonal contraceptive factors and the incidence of breast cancer (P=1.000, OR=0.776). The study concluded that the factors associated with breast cancer in women under 40 years old are age of menarche, breastfeeding history and family history. It is expected for women under 40 years old to routinely perform SADARI (breast self-examination) to prevent and detect early occurrence of breast cancer.

Coffe is one of Indonesia’s leading commodities, known for its diverse flavors and aromas. Traditionally, coffee quality assessment is conducted manually through cupping tests performed by expert panelists. However, this method is subjective and requires considerable time and cost. This study aims to implement an Artificial Neural Network (ANN) using the backpropagation algorithm to classify coffee types based on sensory parameters such as flavor, aroma, acidity level, and body. Simulated data were generated from five common Indonesian coffee varieties: Arabica Gayo, Robusta Lampung, Arabica Toraja, Liberica Jambi, and Excelsa. The results show that the ANN-based classification system with a 4-8-1 architecture achieved an accuracy rate of 93% after 500 training epochs, with a final error value of 0.07. The implementation of this method provides an efficient and objective technological alternative to assist the coffee industry in maintaining product quality and automatically identifying coffee types.    

Carbonate rocks are one of the most important geological resources with a significant role in various industrial sectors, particularly as the main raw material in cement, lime, and construction industries. This study aims to review the characteristics, quality, and industrial potential of three major carbonate rock types—limestone, dolomite, and marble—based on relevant scientific literature. The research employed a literature review method using a qualitative-descriptive approach through analysis and synthesis of previous studies. Data were collected from scientific publications addressing the mineralogical, chemical, and physical aspects of carbonate rocks and their implications for industrial performance. The findings indicate that the quality of carbonate rocks is largely determined by mineral composition (calcite and dolomite), chemical purity (CaO and MgO), and the presence of impurities such as silica, alumina, and iron oxides. High-purity limestone rich in calcite is identified as the most efficient raw material for cement and lime industries due to its stable processing behavior and lower energy requirements. Conversely, dolomite with high magnesium content requires process adjustments to prevent excessive MgO formation during calcination. Marble, both in natural and waste powder form, shows promising potential as a supplementary material in sustainable cement production. Overall, this study emphasizes that understanding the mineralogical and chemical variations of carbonate rocks is essential for optimizing their processing strategies and promoting sustainable industrial utilization

The methods used include field surveys, traffic data collection, design load analysis, and structural simulation using modeling software. The study results indicate that bridge type selection is not only determined by load capacity and cost efficiency, but must also consider sustainability, aesthetics, and the impact on the surrounding ecosystem. This study emphasizes the importance of integrating technical, social, and environmental aspects in bridge planning, so that the resulting design can provide a safe, efficient, and sustainable solution. Thus, bridge planning is not merely a technical process, but also a development strategy that supports connectivity and community welfare.

Type 2 diabetes mellitus (DM type 2) is a chronic metabolic disorder marked by elevated blood glucose due to insulin resistance and impaired insulin secretion. Its prevalence continues to rise worldwide, including in Indonesia. Psychological stress is known to worsen glycemic control by activating the sympathetic nervous system and increasing cortisol levels, which can cause fluctuations in blood glucose. This case report aims to describe the effect of combining Benson relaxation techniques with warm foot soaking on blood glucose regulation in a type 2 DM patient. The subject was Mrs. M, a 52-year-old woman diagnosed with type 2 DM. The intervention was conducted for seven consecutive days and consisted of daily Benson relaxation followed by warm foot soaking for 15–20 minutes. Blood glucose levels were measured before and after each session using a glucometer and analyzed descriptively. After seven days, the patient’s blood glucose level decreased from 248 mg/dL to 186 mg/dL. She also reported improved relaxation, better sleep quality, reduced anxiety, and decreased fatigue. These findings suggest that Benson relaxation helps activate the parasympathetic response and reduce stress hormones, while warm foot soaking supports improved circulation and metabolic processes. In conclusion, the combination of Benson relaxation and warm foot soaking is a simple, safe, and effective complementary therapy to support blood glucose regulation in type 2 DM patients. This intervention can be integrated into self-care routines and community nursing practice as part of evidence-based non-pharmacological management.

Epilepsy is one of the most common chronic neurological disorders in children. Long-term use of antiepileptic drugs carries the risk of Drug Related Problems (DRPs) such as drug interactions, inappropriate dosing, and untreated indications. This study aimed to identify the types and incidence of DRPs in pediatric epilepsy outpatients at Embung Fatimah General Hospital, Batam. This was a descriptive, non-experimental study with a retrospective design. Data were collected from pediatric medical records (<18 years) between January–December 2024, with a total of 45 patients. DRPs were identified using the American Society of Hospital Pharmacist (ASHP) classification. Of 45 patients, the majority were aged 1–5 years (38%) and female (53%). The most frequently used antiepileptic drug was sodium valproate (56.36%). Identification DRPs included drug interactions (63.16%), untreated indications (5.26%), and inappropriate drug selection (5.26%). No cases of overdose or failure to receive medication were found. The most dominant DRP in pediatric epilepsy patients was drug interactions, particularly between valproic acid and folic acid.

Intraoperative hypotension, particularly during spinal anesthesia in cesarean sections or major surgeries, is a common complication that can adversely affect maternal hemodynamics and organ perfusion, including fetal circulation. Vasopressors such as norepinephrine, phenylephrine, and ephedrine are widely used to manage this condition. This study employed a scoping review, defined as a type of research synthesis aimed at mapping the literature on a specific topic or field, providing an opportunity to identify key concepts, research gaps, and types and sources of evidence to inform clinical practice, policy-making, and further research. A systematic search was conducted across 10 recent experimental and clinical studies evaluating the effectiveness and safety of vasopressors in adult patients, particularly ASA I–II parturients, during surgical procedures. The results indicate that norepinephrine tends to maintain blood pressure with a lower incidence of tachycardia compared to ephedrine, while phenylephrine effectively prevents systemic vascular resistance decline but may reduce heart rate and cardiac output in a dose-dependent manner. Effects on fetal cerebral perfusion and cerebral oxygenation were generally similar across vasopressors. No significant differences were observed in neonatal Apgar scores or maternal complications. In conclusion, norepinephrine and phenylephrine are effective alternatives for managing intraoperative hypotension, whereas ephedrine increases cardiac output but may elevate the risk of tachycardia. Selecting the appropriate vasopressor is crucial to ensure maternal and neonatal safety.

The purpose of this study is to assess the impact of halal brands, brand image, and price perceptions on the motivation and purchasing choices of Wardah consumers, as well as to identify the psychological and behavioral factors underlying the phenomenon of "The Wardah Effect" among Indonesian people. This study uses a descriptive quantitative approach supported by qualitative data. A total of 21 Wardah respondents aged 18 to 27 years old in Kudus were selected as respondents through purposive sampling techniques. Data was collected online using a questionnaire with a Likert scale and open-ended questions. The results showed that three main factors greatly influenced "The Wardah Effect", namely value (halal image and pride in local products), economic efficiency (affordable prices), and ease of access (easy to find). Most respondents felt proud of local products (81.0%), found the prices offered affordable (95.2% agreed), and thought that the products were easy to find (90.5%). Halal imagery is also the most influential component, which provides a sense of security and trust (76.2% fully agree). Promotions and advertisements had an impact on 80.9% of respondents. It was concluded that Wardah's purchase decision was based on three types of rationality, namely economic, cultural, and ideological, as well as social-digital, thus making Wardah a symbol of identity and social values for the younger generation.

Extraction is a crucial stage in obtaining bioactive compounds from natural materials that have potential as medicinal, cosmetic, or nutraceutical ingredients. Among the various extraction methods available, maceration remains one of the most widely used techniques due to its simplicity, cost-effectiveness, and ability to maintain the stability of active compounds. The maceration process involves soaking powdered plant material in a suitable solvent at room temperature for a certain period, accompanied by periodic stirring to facilitate the diffusion of active compounds into the solvent. This method is particularly effective for extracting polar and semi-polar compounds such as flavonoids, phenolics, and essential oils that are sensitive to heat. The review shows that the effectiveness of maceration is influenced by several key factors, including the type and concentration of solvent, particle size of the material, duration of soaking, and stirring frequency. The use of ethanol with higher concentrations generally yields greater extract recovery and higher levels of active compounds. In addition, maceration is considered environmentally friendly because it requires no excessive heating and can employ safe, natural solvents. Therefore, despite the development of advanced extraction technologies, maceration remains a relevant, practical, and efficient method for phytochemical extraction, especially in laboratory research and small-scale herbal industries.          

Café retrorika is one of the cafes located in Batu City, Malang, which adopts a green marketing concept with a unique aesthetic touch, combining the concepts of “Retro” and “Eco-friendly”, where almost all of the café’s furniture and decorations are made from recycled materials, such as old windows, used motorcycle tanks, gas cylinders and rims, which are transformed into high-art decorative elements. Awareness of the importance of sustainable business is growing, including in the culinary sector. Cafes and restaurants now compete not only in terms of taste and service but also in their commitment to environmentally friendly concepts. Moreover, today’s consumers are increasingly selective in choosing places to eat that support local products, use environmentally friendly materials, and strive to reduce plastic waste. This is one of the reasons for building cafes with different concepts, as done by the owner and founder of Retrorika café. This study uses a qualitative approach with a case study research type. Data collection techniques include participant observation, interviews and documentation. The result show that Retrorika café was built based on the personal idealism of its owner as a green movement activist, rather than market calculations. The café’s “Retro” identity serves as physical evidence of sustainability practice through the use of used furniture while also creating a nostalgic experience. Its marketing strategy focuses on education through the Re-dukaci program, Retrorika goes to Halokes and Sa-Si-Su as an effort to prove the authenticity of green practices and mitigate greenwashing. These results can be concluded that the founder’s passion shapes the Green Corporate Identity and becomes a source of sustainable competitive advantage that is difficult to imitate.

Cinangka District has not yet implemented a system for separating organic and inorganic waste at the household or community level. Therefore, training on the production of organic fertilizer (POC) and compost using a composter is necessary. This activity was held on June 12, 2025, in Kamasan Village, Cinangka District. A follow-up to this fertilizer training was the creation of a tool to measure the NPK content of fertilizers, allowing for the determination of their appropriate use for specific crops. The results of this activity concluded that processing organic waste into organic fertilizer has the following benefits: 1) Reducing the accumulation of organic waste that can pollute the environment; 2) More economical, as it can reduce the cost of purchasing fertilizers and can even be a business opportunity for fertilizer production; 3) Optimal plantation yields are achieved by using organic fertilizers with the appropriate NPK content for the appropriate crop types

This study aims to analyze the influence of internal control systems and transparency on the accountability of village financial management. This type of research is quantitative and descriptive, using primary and secondary data. Data were collected using questionnaires and literature studies. The population was the Tanjung Datuk community and village officials, Siak Kecil sub-district, Bengkalis district, Riau. The sampling technique used was accidental sampling, with Yamane sample measurements, so the number of samples obtained was 237 people. The data analysis technique used multiple linear regressions with validity, reliability, classical assumptions and hypothesis testing using SPSS software. The results of this study indicate that the internal control system has a positive effect on the accountability of village financial management. However, transparency does not affect the accountability of village financial management. This study provides theoretical implications, especially in completing the theory regarding the influence of the internal control system on accountability and support for the theory of stewardship and legitimacy. This study can then be a reference for the village government in maintaining and improving the accountability of village financial management in implementing the internal control system.

The braking system is a crucial component in a vehicle, where its performance is highly influenced by the wheel's rotational speed and the geometry of the brake pad. This study aims to analyze the impact of wheel rotational speed and variations in pad geometry on the temperature of the brake pad. The braking process generates heat due to friction, which, if not properly managed, can reduce braking performance and accelerate brake pad wear. The experiment was conducted at four levels of wheel rotational speed: 1000 RPM, 1500 RPM, 2000 RPM, and 2500 RPM. The testing system was designed using a braking system simulator equipped with a speed sensor (LM393) and a temperature sensor (K-type thermocouple), which were connected to an Arduino microcontroller and displayed in real-time through a Graphical User Interface (GUI) in MATLAB. The test results indicated that both the geometric shape of the brake pads and the wheel rotation speed significantly affected the resulting temperature. Standard brake pads produced the highest temperature at a speed of 2500 RPM, reaching 63.33°C. In contrast, brake pads with holes offered the best performance by maintaining a lower temperature of only 43.00°C. Furthermore, an increase in wheel rotation speed led to a noticeable rise in temperature; for standard pads, the temperature increased from 36.67°C at 1000 RPM to 63.33°C at 2500 RPM. This demonstrates that RPM is a major factor in heat generation due to friction. The MATLAB GUI effectively visualized the relationship between RPM and temperature, facilitating the analysis and evaluation of the data.

This study aims to analyze the influence of profitability, liquidity, and leverage on firm value, both partially and simultaneously. The background of this study is based on the importance of firm value as an indicator of managerial performance and a factor that attracts investor attention. The approach used is quantitative with a causal-associative research type. The data used is secondary data obtained from the financial statements of 19 companies in the healthcare sector. Based on the analysis, the results indicate that profitability has a positive and significant effect on firm value, indicating that good financial performance can increase market perception of firm value. On the other hand, liquidity and leverage do not show a significant effect on firm value. This indicates that these two factors do not significantly influence market assessments of companies in the healthcare sector that are the object of this study. However, simultaneously, all three variables are proven to have a significant effect on firm value, indicating that although their partial effects are different, all three factors have a collective contribution in shaping firm value. From the results of this study, it can be concluded that profitability is the main factor that plays a role in increasing firm value, while liquidity and leverage require further attention in a more specific context.

The results of burger buns with high-fiber formulations were obtained from the ratio of wheat flour and mocaf flour at 50%:50% with a percentage of beet puree at 50%, this treatment has a fiber content of 11.47%, the water content of 26.10%, ash content 1.58%, fat content 4.33%, protein content 6.53%, carbohydrate content 61.45%, calories 310.89%, specific development volume 4.42%. Of flavor 3,38, color sensory test 3.73, chewiness 3.81, tenderness 3.11. Burger buns with raw materials of mocaf flour and the addition of beet puree as a source of fiber can be one of the practical foods that have good nutritional value for health.

This study aims to analyze product quality at PT. XYZ, particularly focusing on Defects by Dimension, using the Statistical Quality Control (SQC) method. Defect data were collected over the period from April 2024 to March 2025 and analyzed using seven SQC tools, namely the check sheet, histogram, Pareto Chart, Scatter Diagram, and p-Chart. The results indicate that Defects do not always increase in proportion to production volume, and the most dominant types of Defects are Dimensional and Hole Distance, accounting for 73.4% of the total Defects based on the Pareto Chart. The Scatter Diagram shows an upward trend in Defects as production increases up to a certain point, after which the Defect rate decreases as production continues to rise. The p-Chart indicates that the production process remains within statistical control limits, although several samples approach or slightly exceed the upper control limit. Overall, the quality control process is fairly well maintained; however, greater attention is needed to address dominant Defect types and variations near control limits to prevent larger process deviations.

Electronic Medical Records (EMR) are crucial for the quality of healthcare services, but compliance remains a challenge. This study analyzed factors influencing compliance among healthcare workers at a type B private hospital in North Jakarta using a quantitative cross-sectional design with 58 respondents through total sampling. Data were obtained through questionnaires related to individual factors (age, length of service, knowledge), psychological factors (attitude, motivation), and organizational factors (leadership, work design, rewards). The results showed that 72.4% of respondents were compliant. The chi-square test revealed a significant relationship between compliance and age (p=0.042), length of service (p=0.000), knowledge (p=0.001), attitude (p=0.017), motivation (p=0.002), leadership (p=0.046), and rewards (p=0.010), while work design was not significant (p>0.05). Multivariate analysis found age, length of service, knowledge, and leadership as the dominant factors. Healthcare workers with younger age, shorter tenure, good knowledge, positive attitudes, high motivation, good leadership, supportive work designs, and adequate reward systems tend to have higher compliance rates. Improving compliance in completing EMRs depends not only on individual factors but also requires organizational support through effective leadership and management systems. Recommended interventions include improving digital literacy, regular training, strengthening a work culture that emphasizes the importance of medical documentation, and implementing peer learning strategies among healthcare workers to accelerate adaptation and share best practices in completing EMRs.

Learning assessment is a crucial element in the educational process that aims to measure how well students understand the material taught. The tools chosen for measurement have a significant influence on the validity and accuracy of the assessment results. At MAN 2 Bantul, educators generally use two types of measurement tools, namely multiple-choice tests and essay tests. This study aims to assess the effectiveness of essay tests in comparison with multiple-choice tests in assessing student learning achievement at MAN 2 Bantul, using the direct interview method. This study was conducted to gain insight into the views of teachers and students regarding the effectiveness of both types of tests in the educational evaluation process. Data were collected through direct interviews with teachers and students who had experience in using both types of measurement tools. Data analysis was obtained using a descriptive qualitative approach to explore their views and experiences regarding the accuracy and appropriateness of tests in assessing learning outcomes. The findings from the interviews showed that multiple-choice tests were considered more effective and practical in measuring student learning outcomes because they used the JMD (Jogja Madrasah Digital) application, which immediately displayed the scores. However, the teachers also agreed that essay tests provided a more comprehensive analysis of learning outcomes because they encouraged students to think critically. This study recommends the implementation of a combination of both types of exams to make learning evaluation more efficient.
