The Printed Circuit Board (PCB) industry increasingly relies on automation and digitalization to improve efficiency and accuracy in production and distribution processes. One common practice is the use of labels containing product information in the form of barcodes or QR codes, which allow automatic data input and reduce the risk of human error compared to manual writing. However, in current practices, these labels are only attached to PCBs after they have been placed inside casings. This creates a significant limitation, as access to the label information requires disassembling the casing whenever product verification, tracking, or troubleshooting is needed. Such a process not only consumes additional time and resources but also increases the risk of damaging the product. To overcome this challenge, this study proposes the development of a traceability system designed to accurately monitor the location, identity, and status of PCBs throughout the distribution process. The system was implemented as a web-based application capable of generating and printing product information labels in the form of barcodes and QR codes. Each label functions as a unique identifier, ensuring that every PCB can be distinctly tracked from production to final product assembly. All data associated with the labels is automatically stored in a centralized database, providing real-time accessibility, simplifying information management, and enabling faster decision-making in the event of quality control issues. System evaluation was carried out through rigorous testing, which showed a 100% success rate in generating, storing, and retrieving product information without errors. The findings indicate that the proposed traceability system is both effective and efficient, and it offers a practical solution for industries seeking to enhance supply chain visibility, improve product accountability, and reduce operational inefficiencies in PCB distribution and lifecycle management.

This interactive media combines elements of text, images, animation, and digital circuit simulations using CircuitVerse, so students can learn logic gate concepts visually and directly practice them virtually. This integration not only makes it easier for students to understand the theory but also trains problem-solving and critical thinking skills. The findings of this study indicate that interactive learning media based on Adobe Flash CS6 and CircuitVerse has great potential to increase learning motivation, student engagement, and conceptual understanding of logic gate material. This media is also relevant to support the implementation of the Independent Curriculum, which emphasizes project-based learning, independent learning, and complete competency mastery.  

This research is an evaluative study of the old urban area of Kesawan in Medan City, which has been part of the city’s revitalization efforts initiated by the Medan City Government. Kesawan possesses strong historical and colonial architectural character but has undergone functional and visual degradation due to uncontrolled modern urban development. One of the key issues identified is the presence of inactive urban spaces, disconnected from the public realm and lacking social meaning—phenomena recognized in urban theory as lost space. This concept serves as the foundation for evaluating the effectiveness of the revitalization program implemented since 2021. The study employs a qualitative approach using a single-case study method, focusing on Kesawan as a complex urban space. Data were collected through field observations, in-depth interviews with five categories of informants (building owners, visitors, security personnel, street vendors, and architects), and visual documentation. The analysis adopts the theoretical framework of Finding Lost Space by Roger Trancik (1986), which comprises three main approaches: Figure-Ground Theory, Linkage Theory, and Place Theory. These were further elaborated into six evaluative indicators: connectivity, continuity and circulation, enclosure, accessibility, visual orientation, and the meaning and perception of space by the public. The findings indicate that revitalization has brought significant visual improvements and physical enhancements, particularly along the main corridor of Jalan Ahmad Yani I–VII. However, many secondary streets and non-priority areas still exhibit characteristics of lost space, such as disconnected pedestrian paths, underutilized voids, weak spatial integration, and limited social engagement. These conditions suggest that the revitalization outcomes remain uneven and predominantly cosmetic in certain areas. The study recommends integrating spatial and social approaches in future urban revitalization policies to ensure that public space functions can be restored holistically, sustainably, and contextually in line with local identity.

The Community Service Program (KKN) is an intracurricular activity that is mandatory for students as a form of community service. In this context, the KKN group R1 of Janabadra University Yogyakarta conducted a service activity in Banyurejo Village, Yogyakarta City, for six weeks. This activity carried the main theme of community empowerment in environmental management, with a primary focus on increasing awareness of the economic potential of waste through the implementation of an Environmental Workshop with the theme "Waste as Economic Potential: Creating an Independent and Clean Village." This workshop was the core agenda that involved the active participation of residents in discussing and practicing waste management that was wise, economically valuable, and environmentally friendly. To support this main activity, several supporting programs were also implemented, including: Ceria Class as a medium for environmental education for children, the establishment of a Waste Bank, joint exercise activities with residents, village clean-up actions, synergy with the PKK women's group, and educational seminars on the environment and health. All activities were designed with a community-based educational and participatory approach, to encourage direct community involvement in creating change. During the implementation period, this program showed positive results. There was an increase in public awareness of the importance of structured and sustainable waste management. Furthermore, residents have begun to demonstrate their initiative by establishing neighborhood-level waste banks, demonstrating their commitment to community-based waste management. Participation from various community elements, including children, housewives, and community leaders, is key to the success of this initiative. The success of the Janabadra University Community Service Program (KKN) group R1 is expected to serve as a model for other regions in designing and implementing community empowerment programs, particularly in the environmental sector.

Night shift workers in the modern retail sector, especially minimarkets such as Alfamart Makassar City, often face the risk of health problems due to changes in circadian rhythms, irregular diets, and lack of nutrition education. Work patterns that require them to be active at night have an impact on metabolic imbalances, sleep quality disorders, and unhealthy eating habits. Most workers tend to eat fast food that is high in calories, fat, and sugar, but low in fiber and micronutrients. This condition can increase the risk of fatigue, decreased immunity, and impaired concentration at work. This study aims to evaluate the effectiveness of nutritional nursing interventions in improving the diet and physical condition of night shift workers. The research approach used was descriptive with a case study method on 32 Alfamart workers who worked night shifts. The research was carried out for three days, namely on May 24-26, 2025. The interventions provided include nutrition education through brief counseling, monitoring of food and fluid intake, and assistance in developing a meal schedule that is in accordance with night work patterns. The results of the study showed a significant improvement in nutritional behavior. After the intervention, 84% of participants started implementing a healthy diet with a frequency of twice per shift, 93% increased their water consumption as recommended, and 72% felt refreshed and did not get tired easily while working. In addition, as many as 78% of participants showed high compliance with the nutritional recommendations given. These findings prove that nutritional nursing interventions have an important role in the promotion of occupational health. Proper nutrition education not only increases workers' awareness of the importance of a healthy diet, but also has an impact on increasing the productivity and welfare of night shift workers. Therefore, nutrition promotion programs should be part of the management policies of retail companies to maintain employee health.

Air circulation and natural lighting are among the key aspects influencing the comfort of room usage, particularly in dormitory buildings inhabited by university students. This study aims to explore thermal comfort more deeply, focusing on air circulation and natural lighting within student dormitory rooms in the Riau Islands. A qualitative method was employed, collecting up-to-date data on the selected building. Building simulations using Computational Fluid Dynamics (CFD) and DIALux were conducted to analyze the speed of air circulation and the quality of natural lighting within the rooms. The results reveal that prior to evaluation, the dormitory rooms faced thermal issues related to poor air circulation and insufficient natural lighting. Wind speed was recorded at less than 2 m/s, and the incoming and outgoing airflow collided due to the presence of only one ventilation access. The evaluation using cross-ventilation through room openings showed a positive impact on indoor air circulation, increasing wind speeds to 2–4 m/s. The cross-ventilation concept also enhanced the discharge and exchange of indoor air, preventing air stagnation. In terms of natural lighting, the simulation showed that lighting intensity in several rooms was below the minimum standard of 250 lux, particularly in areas far from the window openings. After modifications to the window layout and the addition of secondary light-transmitting elements, the lighting level significantly improved to meet the recommended standard. These findings highlight the importance of incorporating both passive ventilation and natural lighting strategies in student dormitory designs. Improving these environmental aspects not only enhances thermal comfort but also supports the health, productivity, and well-being of the residents. This study contributes to the growing body of research on sustainable dormitory design and can be used as a reference for future architectural planning and policy improvements.

This research is motivated by the rampant circulation of repackaged products that have not been fully supervised. Therefore, it is necessary to analyze the legal protection provided to consumers and the effectiveness of the role of the Food and Drug Supervisory Agency (BPOM) in conducting supervision. The purpose of this study is to determine the legal protection provided to consumers of packaged food products and to determine the extent to which BPOM carries out its role as a supervisory agency in ensuring the safety of these products. This research uses a normative legal approach with a qualitative approach, through literature study and interviews as a complement. The results show that business actors are required to re-register repackaged products in accordance with food safety regulations. This is a preventive measure to ensure that products in circulation are safe for consumption and provide effective legal protection for consumers. The findings also indicate that BPOM supervision still needs strengthening, both in terms of regulations, resources, and community outreach.  

This paper examines how The Picture Dorian Gray by Oscar Wilde marks a critical turn in which he critiques late-Victorian upper-class privilege and moral immunity. While previous scholarship has predominantly analyzed the novel as a moral allegory or aesthetic treatise, this study employs cultural materialism as a theoretical framework to demonstrate how Wilde uses Dorian’s isolation of his portrait and subsequent hedonistic experimentation as symbolic representations of the aristocracy’s ability to shield him from moral and social consequences. Wilde’s text reveals how the English aristocracy could embody ideals of beauty and reap princely treatment while committing debauchery without reproach. Through Culler’s close reading method toward this novel, especially chapters eight and nine, this analysis reveals how Dorian’s act of hiding the portrait symbolizes social denial, while his obsessive aesthetic consumption reflects the practices of the leisure class. This shows that Wilde hints Dorian’s social circle accepts his sensual life simply because his appearance remains unmarred–a commentary on class privilege. By examining the specific textual elements and historical context of—especially—chapters eight and nine of this novel, this study contributes to the understanding of how Wilde’s novel serves as both a product of and commentary on the class structures and moral hypocrisy of late-Victorian England.

Bekasam is a traditional Indonesian fermented food produced through spontaneous fermentation involving microorganisms, particularly lactic acid bacteria (LAB). LAB plays a crucial role in the fermentation process by producing lactic acid, which lowers pH, inhibits pathogenic microbial growth, and enhances flavor and food safety. This study aimed to identify and characterize LAB isolated from fermented snakehead fish (Channa striata) based on Gram staining and colony morphology. The research began with bacterial isolation using NA Nutrient Agar, followed by macroscopic observation of colony characteristics including shape, edge, elevation, color, and size. Subsequently, Gram staining was performed to determine the cell wall structure and microscopic morphology of the bacteria. The results showed that the bacterial isolates from bekasam generally had circular colonies, white to cream in color, smooth surface, and were Gram-positive rod-shaped cells. In conclusion, bekasam from snakehead fish contains dominant lactic acid bacteria with distinctive colony morphology and Gram-positive characteristics, indicating potential as a natural starter culture for food fermentation.

Introduction Maternal Mortality Rate (MMR) is one of the indicators to determine the quality of maternal health services in Indonesia. Obstetric complications greatly affect MMR, including long first stage of labor. Moxa therapy is a traditional therapy that uses mugwort plants (artemisia vulgaris) to provide warmth to acupuncture points in the body. The goal is to stimulate energy circulation (QI) and blood. Method This study aims to determine the differences before and after intervention related to the duration of labor of inpartu mothers after giving mugwort moxa. This study is a pre-experimental study with a one group pretest-posttest study design conducted on inpartu mothers in the first stage. Results The calculated value obtained from the calculation using the T-test was 0.015, so the calculated t value <0.05 (0.15 <0.05) so it can be said that moxa therapy affects the duration of the first stage of labor. The conclusion of this study is that there is a significant relationship between mugwort moxa therapy and the duration of labor of inpartu mothers in the first stage of labor at the Malang Regional Health Facility. Mugwort moxa therapy tends to shorten the duration of the first stage of labor.

Panji Kahirupan Dance is a Cirebonese mask dance created by H. Taufik Hidayat, the founder of Sanggar Ki Bagus Rangin. This dance portrays the journey of human life, from pre-birth to adulthood, inspired by the changing characters (wanda) of the Cirebon mask tradition. This study aims to describe and analyze the symbolic meanings embedded in the Panji Kahirupan Dance. The research uses a qualitative method with a semiotic approach, allowing the researcher to explore both the denotative and connotative meanings of the symbolic elements in the dance. Data were collected through observation, interviews, and documentation, and validated using triangulation of techniques and sources. The data analysis involves data reduction to select relevant information, data presentation to synthesize findings, and conclusion drawing to interpret the symbolic meanings of each performance element. The costumes carry symbolic meanings through their colors: white represents the sanctity of life’s beginning, yellow symbolizes spirit, and red denotes ambition. The soft gamelan music contributes to a spiritual and contemplative atmosphere. The floor patterns, such as circles and straight lines, symbolize the life cycle and life’s purpose.

This study aims to analyze the impact of monetary policy on income inequality in Indonesia over a certain period of time. Monetary policy implemented by Bank Indonesia plays an important role in maintaining macroeconomic stability through instruments such as interest rates, inflation, and the amount of money in circulation. However, the implementation of this policy also has an impact on the distribution of community income. This study uses a quantitative approach with secondary data in the form of time series analyzed using econometric regression methods to measure the effect of monetary policy variables on the income inequality index (Gini Ratio). The results of the study show that variables such as the benchmark interest rate and inflation have a significant relationship to income inequality. When inflation increases, the purchasing power of the lower middle class decreases more sharply than the upper class, thus widening the gap in inequality. Conversely, controlling inflation through appropriate interest rates can help reduce economic disparities. This study provides important meaning for policy makers to pay more attention to the distribution aspect in determining monetary policy so that economic growth can be more inclusive and equitable.

Dextromethorphan (DXM) is a commonly used nonprescription cough suppressant that has gained field of science attention with its growing complex pharmacological effects and increased incidences of nonmedical use. This review is focused on pharmacokinetic, pharmacodynamics and CNS effects of DXM, especially on its action mechanism and the interaction with neural circuits and neurotransmitter systems. Although DXM has retained clinical utility as an antitussive, and has demonstrated potential as an off-label agent for neuropsychiatric disease, the recreational use of high doses can have harmful effects on the nervous system. At high doses DXM is capable of dissociation and hallucination similar to those induced by some opioids and NMDA antagonists, altering both mental status and cognition while being associated with neurotoxic effects. In this article, review and compare the similarities and differences between DXM and classic opioids in terms of their potential for abuse and their neurological effects. By case examples and existing epidemiological data, it also highlights the mounting abuse of DXM, most notably by children and young adults, posing a pressing public health challenge. Legislation on DXM is also described and differences in legislative response worldwide are highlighted. Finally, the article finishes by emphasizing the requirement for further studies involving other disciplines to detail the long-term neurological consequences of DXM abuse and to promote integrated public health interventions targeting education, prevention, and clinical treatment.

The increasing trend in skincare usage, particularly whitening products, has led many business actors to market their products extensively without regard for legal compliance. One notable issue is the circulation of blue-label skincare products, which should only be provided with a doctor's prescription. The research employs a normative juridical method with a qualitative approach, utilizing interviews and literature study. The findings reveal that legal protection for consumers in the use of blue-label skincare products remains suboptimal. These products often contain active ingredients such as corticosteroids or antibiotics, which should only be used under a doctor's prescription and supervision. However, in practice, many business actors continue to sell them freely via online marketplaces and social media platforms. This not only violates BPOM regulations and health laws but also poses a direct threat to consumer safety. Furthermore, business accountability is still lacking, as evidenced by the insufficient transparency regarding product content, usage instructions, and distribution permits.
