PT. Bukit Baiduri Energi (BBE) is a coal mining company that utilizes hauling roads as the main infrastructure for material transportation. This study focuses on a 1.7 km road segment selected as the object of technical evaluation. The objective of this research is to analyze the effect of road geometry improvements on hauling time efficiency and equipment productivity. The method employed includes direct field measurements and calculations of operational parameters such as travel time, cycle time, and productivity. The results indicate that improvements in road grade reduced travel time from 10.13 minutes to 9.86 minutes. This reduction was followed by a decrease in cycle time from 16.29 minutes to 16.22 minutes. In addition, productivity increased from 65.4 bcm/hour to 66.69 bcm/hour. Also, improvements in curve radius and superelevation were implemented on the hauling road. These improvements resulted in a further decrease in travel time from 9.86 minutes to 8.6 minutes. Consequently, the cycle time also decreased from 16.22 minutes to 16.18 minutes. The productivity of hauling equipment increased from 66.69 bcm/hour to 67.02 bcm/hour. Overall, the evaluation of road geometry provided a positive contribution to operational performance. The productivity of overburden removal increased from 65.4 bcm/hour to 67.02 bcm/hour, representing an improvement of 2.48%.

Hydrocephalus is defined as active distension of the brain’s ventricular system, resulting from inadequate flow of cerebrospinal fluid from its site of production to its site of absorption into the systemic circulation. Hydrocephalus can affect anyone at any age; pediatric hydrocephalus affects 1 in 1,000 live births and is the most common cause of brain surgery in young patients. Hydrocephalus is a pathological condition characterized by abnormal accumulation of cerebrospinal fluid (CSF) due to increased production, impaired flow, or reduced absorption. Ventricular enlargement occurs in response to increased CSF volume and can lead to structural damage to the brain parenchyma. This condition can be congenital or acquired. One key point in prenatal diagnosis is the differentiation between fetal hydrocephalus and non-hypertensive ventriculomegaly. The former qualifies for intrauterine treatment with good outcomes. However, the latter can result in either favorable or catastrophic outcomes due to a damaging etiology, as seen in viral infections such as Zika virus. For an accurate diagnosis, fetal MRI is performed to detect brain anomalies, in addition to fetal ultrasound (to detect common complications), karyotype testing, and TORCH testing (toxoplasma, rubella, cytomegalovirus, herpes simplex). Obstetric management of fetal hydrocephalus depends on the gestational age at diagnosis and the presence of other anomalies. Treatment options include termination of pregnancy before the fetus is viable, placement of a ventriculoamniotic shunt, cephalocentesis before delivery, and/or cesarean section.

Land rights disputes arising from overlapping land certificates remain a complex agrarian law issue frequently encountered in Indonesia. This phenomenon reflects weaknesses in the land administration system, particularly in data collection, land measurement, and certificate issuance. Such disputes create conflicts, legal uncertainty, and reduced public trust in the land registration system. In practice, these disputes are generally resolved through civil litigation procedures in the District Court. This study aims to comprehensively analyze civil procedural law in resolving land rights disputes involving overlapping certificates and to examine the evidentiary strength of land certificates in judicial proceedings. This research employs a normative legal method using statutory and conceptual approaches, supported by primary and secondary legal materials. The findings indicate that dispute resolution begins with the filing of a lawsuit, followed by mediation, court examination, and the evidentiary process as the most crucial stage in determining lawful ownership. Land certificates serve as strong evidence; however, they are not absolute, as they may be challenged if administrative or substantive legal defects are identified. Judges play a central role in assessing certificate validity by considering land history, physical possession, good faith, and compliance with legal procedures. Nevertheless, the effectiveness of dispute resolution still requires improvement through better land administration, enhanced data accuracy, and stronger institutional integration.

Typhoid fever during pregnancy can lead to complications such as uteroplacental infection, miscarriage, and vertical transmission, which causes neonatal typhoid. Typhoid fever is found worldwide and is highly prevalent in developing countries, particularly in tropical regions. It is estimated that there are 11–21 million cases per year and approximately 128,000–161,000 deaths per year; the majority of cases occur in Southeast Asia, South Asia, and Sub-Saharan Africa. Salmonella typhi is a gram-negative bacterium capable of intracellular survival. Symptoms in typhoid patients vary among different groups. While pregnant women with typhoid are more likely to exhibit coughing, non-pregnant patients more frequently report nausea/vomiting compared to pregnant patients. The effects of typhoid fever on pregnancy result from prolonged high fever and poor general health, which can lead to miscarriage, preterm labor, and intrauterine fetal death, especially if the infection occurs during the first or second trimester. Morbidity and mortality rates may be higher in pregnant women. Pregnancy itself does not affect the course of the disease. Prevention of typhoid fever involves adopting a clean and healthy lifestyle, as well as receiving the typhoid vaccine. Two effective vaccines are available for typhoid fever. The live-attenuated oral vaccine (Ty21a) requires four doses, administered 48 hours apart, without concurrent use of antibiotics or antimicrobial medications. Due to reduced gastrointestinal motility in early pregnancy and frequent nausea and vomiting associated with symptomatic gastroesophageal reflux requiring acid-reducing therapy, we do not recommend the Ty21a oral vaccine for pregnant patients.

This article examines the re-actualization of teachers’ social competence within the digital learning ecosystem. The rapid development of technology has transformed conventional learning into digital-based environments, which significantly affect the patterns of interaction between teachers and students. This transformation often leads to reduced direct communication, emotional connection, and social engagement in the learning process. Therefore, this study aims to explore the importance of strengthening teachers’ social competence and to identify strategies for its re-actualization in digital learning contexts, particularly in early childhood education. This study uses a qualitative approach through a literature review by analyzing relevant journals, books, and scientific articles published in recent years. The findings indicate that teachers’ social competence remains a crucial factor in creating meaningful learning, even in virtual environments. Effective communication, empathy, and interactive engagement must be adapted to digital platforms. The study also highlights several strategies, such as integrating humanistic approaches, optimizing interactive media, and enhancing digital communication skills. These findings imply that strengthening teachers’ social competence is essential to support effective and holistic learning in the digital era.

Instagram social media addiction has become an increasingly common phenomenon among university students. Excessive use of Instagram can negatively affect mental, social, and academic well-being, and may increase the risk of social anxiety. Students who experience Instagram addiction tend to have reduced direct social interaction, and fear of negative evaluation from others, which are key factors contributing to social anxiety. This study aims to determine the relationship between Instagram social media addiction and social anxiety among students. This study used a quantitative approach with a cross-sectional design. The sample consisted of 105 respondents selected using purposive sampling. The instruments used were the Instagram Addiction Scale (TIAS) and the Social Anxiety Scale for Social Media Users (SAS-SMU). Data analysis was conducted using the Chi-Square test. The results showed that most respondents had a moderate level of Instagram addiction (56.2%) and a moderate level of social anxiety (68.6%). The Chi-Square test indicated a significant relationship between Instagram addiction and social anxiety, with a p-value < 0.001 (p < 0.05). There is a significant relationship between Instagram addiction and social anxiety among students. However, the relationship is not always linear, as higher levels of addiction do not necessarily correspond to higher levels of social anxiety.

The high volume of fishery waste often poses an environmental burden if not managed appropriately. Conversely, the circular economy concept offers sustainable solutions aligned with Maqasid Shariah principles in environmental preservation (Hifz al-Alam). This study aims to educate and implement the processing of fish waste into high-quality animal feed that meets halal standards (halalan thayyiban). This research employs a qualitative approach using the Asset-Based Community Development (ABCD) method. The stages include socializing the concept of Sharia circular economy, technical training on waste processing, and nutritional content testing of the feed. The findings indicate an 80% increase in community understanding regarding the economic value of waste. Technically, the fish waste processing successfully produced an alternative animal feed with high protein content, free from najis (impurity) through a purification process according to Islamic jurisprudence (fiqh). This education proves that the integration of circular economy and Sharia principles not only reduces environmental impact but also creates sustainable economic added value for local communities.

The study highlights the importance of spirituality as a foundational framework for shaping adolescents’ life orientation in the complex digital era, marked by pervasive distractions and fragmented meaning. Ignatian spirituality, emphasizing reflection and lived experience as loci of encounter with God, provides a contextual approach to help adolescents construct deeper existential meaning. The study aims to examine how reflective practices within this framework support students of SMK Katolik St. Mikael Surakarta in internalizing spiritual values and navigating digital challenges. Using a qualitative descriptive case study design, data were collected from 195 reflective writings of twelfth-grade students and reduced to 90 representative samples. The film Hacksaw Ridge was employed as a reflective stimulus to enhance affective and existential engagement. Data analysis was conducted using the four pillars of Jesuit education: Competence, Conscience, Compassion, and Commitment. The findings reveal that all reflections contain at least one element of the 4C framework integrated with Ignatian spirituality. Reflection serves not only as a medium of self-expression but also as a transformative process fostering moral awareness, social sensitivity, and commitment to action. It effectively enables students to process both personal and digital experiences into meaningful learning. The study affirms the strong relevance of integrating spirituality, reflection, and Ignatian pedagogy in contemporary education, contributing to the formation of reflective, value-oriented individuals committed to the common good.

Choux pastry relies heavily on eggs to form its cavity structure and sensory characteristics. The use of duck eggs can improve physical quality due to their higher protein and fat content compared to chicken eggs. This study aims to analyze the differences in organoleptic quality between choux pastry with 100% chicken eggs and 25% duck egg substitution. The experimental quantitative study involved 50 panelists using a hedonic scale questionnaire and analyzed descriptively. The results showed that 25% duck egg substitution significantly improved texture firmness and provided a more savory taste. However, in terms of aroma, the sample with duck egg substitution scored lower due to a sharper fishy aroma. Although 25% duck egg substitution effectively improved the physical structure, it is recommended to add aromatic ingredients to reduce the distinctive duck egg aroma. These findings provide insights into the development of choux pastry with duck egg substitution to improve physical quality without sacrificing desired organoleptic characteristics.

Sign language recognition is one of the areas of image recognition and image processing technology that is developing rapidly in human-computer interaction. This technology really helps the deaf and speech impaired in communicating with non-disabled people. This research aims to examine the optimization of an object tracking system in sign language using the Gaussian Mixture Model (GMM) and Kalman Filter by including the Region of Interest (ROI). The proposed system consists of three main components, namely hand detection, object extraction, and classification. Hand detection is done using the Kalman Filter to track hand movements accurately. Next, Region of Interest (ROI) features, such as shape, direction and movement features, are extracted from the detected part of the hand. These features are fed into a Gaussian Mixture Model (GMM) classifier, which can recognize sign language based on the extracted features. With the combination of GMM and Kalman Filter in this research, it can increase accuracy in object tracking, reduce interference from the background, and ensure the tracking focus remains on important objects. The dataset used is in the form os SIBI alphabet symbols, namely A-Z with the amount of data for each class, namely 620 images. Based on the research result, model testing using GMM, Kalman Filter and ROI produces higher accuracy of 99%, while model testing using GMM and ROI produces accuracy of 90%.

Breast cancer has a high global incidence and is the most prevalent cancer among women. Chemotherapy is a primary treatment option, but it may cause various physical and psychological side effects that can reduce patients’ quality of life. This study aimed to describe the characteristics of breast cancer patients undergoing chemotherapy and examine the relationship between chemotherapy side effects and quality of life at the outpatient unit of Ciremai Hospital. A cross-sectional analytical observational design was applied, with 30 patients receiving chemotherapy between May and July as the sample. Data were collected from medical records and the Indonesian version of the WHOQOL-BREF questionnaire, then analyzed using Spearman rank correlation. Most patients were aged 40–60 years, had a senior high school education, were housewives, and were in the 2nd or 5th chemotherapy cycle. Frequently reported side effects included nausea, vomiting, decreased appetite, early satiety, dizziness, sleep disturbances, body pain, and alopecia, mostly categorized as moderate. Most patients had a relatively poor quality of life. The analysis indicated a strong positive correlation between chemotherapy side effects and patients’ quality of life, with a Spearman correlation coefficient of 0.604 (p = 0.000 < 0.05), demonstrating a significant and strong relationship.

 Background: Perineal pain due to episiotomy is a common complaint experienced by postpartum mothers and can affect patient comfort, mobility, and recovery. Nonpharmacological pain management is needed to help reduce discomfort with minimal risk of side effects. Objective: This study aimed to determine the effectiveness of applying cold compresses using ice packs in reducing perineal pain intensity in postpartum mothers with episiotomy. Methods: The study used a descriptive case study design in three vaginal postpartum patients with episiotomy who were treated in the postpartum ward. The intervention involved applying cold compresses using ice packs to the perineal area for 10–15 minutes, as per nursing procedures. Pain was measured using the Numeric Rating Scale (NRS) before and after the intervention. Findings: The results showed a decrease in pain intensity in all patients after the application of cold compresses. Patient P1 experienced a decrease in pain score from 5 to 4, patient P2 from 6 to 5, and patient P3 from 5 to 4, with an average decrease of 1 point. Implications: Cold compresses using ice packs have the potential to be an effective non-pharmacological nursing intervention to help reduce perineal pain and improve the comfort of postpartum mothers with episiotomies during the care period.

Microplastics are extremely small plastic particles that have become a major concern in public health and environmental studies. This literature review aims to discuss the sources of microplastics, their routes of exposure to the human body, their distribution in organs, and their potential health impacts. The method used was a literature review of scientific articles and reports published from 2021 onward, retrieved from Google Scholar, PubMed, ScienceDirect, and official websites of organizations such as the WHO, OECD, and the World Bank. The review findings show that microplastics originate from plastic waste, synthetic clothing, cosmetics, vehicle tires, and food packaging. These particles have been detected in blood, lungs, the placenta, feces, and various human tissues, indicating that human exposure is widespread. However, evidence from human studies is still limited, so cause-and-effect relationships cannot yet be confirmed with certainty. Based on these findings, further research is needed to better understand the long-term health effects of microplastics. In addition, efforts to reduce single-use plastics, improve waste management systems, and increase public education are essential to reduce exposure and prevent future health risks.

This study explores the acceptance of the Free Nutritious Meal Program (MBG) at SD Inpres Gere through William of Ockham's negative rights framework, focusing on freedom from external interference. As a positive rights policy (the right to services), the MBG has the potential to conflict with the principles of individual subjective rights (negative rights). Ockham emphasized that every individual has a personal sovereignty that must be free from interference from external authorities. Using qualitative research methods through literature studies and interviews, this article analyzes the risk of standardizing consumption that can reduce individual autonomy in determining their private needs. The analysis shows that although the MBG has a noble aim to fulfill the right to life, its implementation risks becoming a form of state paternalism that harms citizens' negative freedoms if not accompanied by strict limits on power. This paper concludes that to align with Ockham's principle of individual subjective rights, the MBG program must continue to respect the private space and diversity of individual choices without creating dependency that erodes the sovereignty of legal subjects.

This study aims to analyze the influence of red tape on public satisfaction with public services in Indonesia. The research focuses on the definition of red tape, the characteristics of administrative procedures in public services, the level of public satisfaction, the influence of red tape on public satisfaction, and the factors influencing the relationship between red tape and public satisfaction. This study used a library research method with a qualitative descriptive approach. Data were obtained through collecting various literature sources such as books, scientific journals, articles, and previous research results relevant to the research topic. The results indicate that red tape is a long, complicated, and excessive bureaucratic procedure that hinders the effectiveness of public services. Furthermore, the results indicate that the quality of human resources, service transparency, bureaucratic culture, and the use of information technology are factors influencing the relationship between red tape and public satisfaction. Digitalization of public services and bureaucratic reform are important solutions to reduce red tape and improve the quality of public services in Indonesia. Thus, it can be concluded that red tape has a significant influence on the level of public satisfaction with public services. Therefore, the government needs to simplify administrative procedures and improve service quality to create effective, efficient, and community-oriented public services.

This study examines young people’s perceptions of the Free Nutritious Meal Program (Makan Bergizi Gratis/MBG) and its impact on public trust in the government. The MBG program is one of the Indonesian government’s strategic policies aimed at improving nutritional quality, particularly for students, while supporting social welfare and human resource development toward Indonesia Emas 2045. In the digital era, social media plays a significant role in shaping public opinion, especially among Generation Z, who actively consume and disseminate information through online platforms. This research employed a qualitative descriptive approach with in-depth interviews, social media observations, and documentation studies as data collection techniques. The participants consisted of young people aged 18–25 years in Bandar Lampung selected through purposive sampling. The findings indicate that most informants perceive the MBG program positively because it is considered relevant to community needs, particularly in improving children’s nutrition and supporting economically vulnerable groups. However, public trust in the government remains conditional due to concerns regarding transparency, uneven distribution, food quality, and program supervision. The study also reveals that young people distinguish between support for the program itself and trust in the government as an institution. Positive perceptions of the program can increase political trust, but implementation weaknesses may reduce confidence in government performance. Therefore, transparency, consistency, and effective public communication are essential factors in strengthening public trust and ensuring the sustainability of the MBG program.

Contemporary Javanese music, particularly Campursari, blends traditional gamelan instruments with modern genres such as pop, dangdut, and keroncong. This hybrid style has gained popularity among Millennials and Generation Z, who often perceive it as familiar, calming, and emotionally comforting. This study examines whether listening to contemporary Javanese music influences the sleep quality of Generation Z in Yogyakarta. A quantitative research approach was employed using a survey distributed through Google Forms to 50 participants aged 19–26 years. The questionnaire measured listening frequency, emotional responses to the music, and perceived sleep quality using a Likert scale. The collected data were analyzed using SPSS with descriptive statistics, including the Kolmogorov–Smirnov normality test, linear regression, and tests for heteroscedasticity and multicollinearity. The results indicate a positive relationship between listening to contemporary Javanese music and improved sleep quality. The familiar and emotionally soothing characteristics of Campursari appear to help listeners relax and reduce stress before sleep. These findings suggest that culturally rooted music may serve as a simple, non-pharmacological approach to supporting better sleep and emotional well-being among young adults..
