This research aims to develop and evaluate the performance of a steam plant prototype designed as an alternative source of electrical energy to support the Vessel to Grid (V2G) concept. Utilization of backup energy on ships is becoming important as electricity demand increases and demands for a more sustainable electrical system. This system relies on ESP32 microcontroller technology as a control center that functions to monitor and control several key parameters, including steam pressure, combustion temperature, boiler water level, and the generated electrical voltage. The research method used is an experiment with a static and dynamic testing approach. Static testing is carried out to measure the performance of main components such as the boiler, turbine, and generator separately, while dynamic testing focuses on evaluating the overall system by involving the integration of sensors and supporting actuators. The test data is then analyzed quantitatively to determine the system's response to variations in steam pressure, temperature, and other operational conditions. The results show that the steam produced by the boiler is able to rotate the turbine, thereby driving the generator to produce electricity. The maximum voltage achieved is 25.7 volts at a steam pressure of 50 psi. The highest energy conversion efficiency was recorded at 4%, while the lowest efficiency was 0.9%. These findings demonstrate that, despite its relatively low efficiency, the prototype can function as an alternative energy source and emergency backup solution. Thus, this research provides an initial contribution to supporting the implementation of the V2G concept through the development of a small-scale steam plant-based energy conversion system.

Background: Stroke is a health condition that significantly impacts quality of life and causes physical and mental disability, as well as death, in both productive and elderly individuals. The loss of bodily functions in stroke patients can hinder productivity and reduce the fulfillment of ADL (Activities of Daily Living). Dependence in ADL is the inability to perform all or some activities and the need for assistance from others. The high incidence of stroke in patients and its role as a leading cause of disability makes it difficult for stroke patients to perform daily activities, causing mental and emotional disturbances, reducing productivity and quality of life. The loss of independence and mobility in stroke patients necessitates family support, as they play a crucial role in the care and rehabilitation of their loved ones. Objective: The purpose of this study was to determine the relationship between family support and the fulfillment of daily living (ADL) in stroke patients. Methods: This study employed a correlational analytic method with a cross-sectional approach. A purposive sampling technique was used for the sample, employing 89 respondents. Data analysis used the Spearman rank sum. Results: The Spearman rank sum analysis yielded a ρ value of 0.000, less than 0.05, and an r value of 0.827 (very strong). Therefore, it can be concluded that there is a very strong relationship between family support and the fulfillment of daily needs (ADL) in stroke patients at Sunan Kalijaga Regional General Hospital, Demak.

Hypertension is a condition characterized by an increase in blood pressure, defined as systolic values ≥ 140 mmHg or diastolic values ≥ 90 mmHg, and it remains one of the most common health problems experienced by the elderly. Non-pharmacological approaches such as low-impact aerobic exercise are recommended, as this type of exercise is performed at a low to moderate intensity for 20–50 minutes, three times a week. It has been shown to strengthen and maintain the functions of the heart, lungs, blood circulation, muscles, and joints, thereby contributing positively to the management of high blood pressure. This study aims to determine the effect of low-impact aerobic exercise on blood pressure among elderly patients with hypertension through the application of evidence-based practice. A quantitative case study approach was employed to gain a deeper understanding of changes in blood pressure following the intervention. Three elderly respondents diagnosed with hypertension were involved and instructed to perform low-impact aerobic exercise for three consecutive days. The results showed a decrease in blood pressure among all respondents, although the outcomes varied. The first respondent experienced changes from 140/80 mmHg to 130/70 mmHg and 130/90 mmHg, the second respondent from 150/90 mmHg to 160/80 mmHg and then 150/70 mmHg, and the third respondent from 150/80 mmHg to 110/70 mmHg and 130/70 mmHg. These findings indicate that low-impact aerobic exercise has a positive effect in reducing blood pressure, despite some variability between individuals. In conclusion, low-impact aerobic exercise is proven to help control blood pressure in hypertensive patients. This study highlights the importance of encouraging hypertensive individuals to adopt regular and independent low-impact aerobic exercise as a simple strategy to maintain stable blood pressure and improve overall quality of life.

The development of digital technology and the impact of the pandemic have shifted the learning paradigm in elementary schools from traditional face-to-face models to technology-based online systems.

This research examines the aesthetic value of the selendang (sash or shawl) worn by the sindhen (female singer) in wayang kulit purwa (Javanese shadow puppet) performances, and the shift in its meaning amidst the current of digitalization. The selendang, as an element of attire, functions not only as an aesthetic complement but is also laden with philosophical and symbolic meaning in Javanese culture. Traditionally, the selendang worn by a sindhen possesses aesthetic value that emanates from the choice of motifs, colors, and the way it is worn, reflecting elegance, social status, and spiritual depth. In performances, the selendang also serves as a dance prop that enhances movement and strengthens the sindhen's expression. The era of digitalization brings new challenges and opportunities for traditional performing arts, including wayang kulit purwa. This study employs a qualitative approach with literature review and observation of both live and digitally broadcasted wayang kulit performances. The results indicate that in the current digital era, a shift has occurred in several aesthetic aspects of the sindhen's selendang. There is a trend towards using more diverse and modern materials and motifs, sometimes adapting techniques like digital printing to create more visually appealing on-screen presentations. Nevertheless, the core values of the selendang as a symbol of refined character and artistic beauty are maintained, and even further explored to cater to a broader and more modern audience. The digitalization of the performance stage also influences the sindhen's interaction, where the selendang is sometimes used more dynamically

Marketing activities of limited liability companies (LLC) in Indonesia are not merely business strategies but also legal activities that entail juridical consequences. The increasingly complex dynamics of modern marketing, including digital marketing, e-commerce, and the utilization of consumer personal data, demonstrate that marketing activities cannot be separated from business law regulations, whether related to consumer protection, fair competition, electronic information, or personal data protection. Marketing by LLC in Indonesia is regulated by various laws aimed at creating fair, transparent transactions while avoiding practices that could harm consumers. From a business law perspective, marketing in Indonesia, especially within limited liability companies, plays a crucial role in maintaining the smooth operation of businesses that benefit not only the company but also the wider society, including consumers. Marketing activities by LLC must consistently adhere to the principles of law, including consumer protection and the obligation to ensure transparency in every promotional activity or advertisement. This study employs a normative juridical method with both statutory and conceptual approaches. The analysis is conducted qualitatively through systematic and teleological legal interpretation, supported by secondary legal materials such as academic literature and recent scholarly articles on business law and marketing. The findings reveal that marketing activities of limited liability companies are closely intertwined with business law, as all contracts, promotions, and marketing strategies constitute legal acts that must adhere to the principles of honesty, transparency, and fair competition. Revenue growth through effective marketing can only be achieved sustainably if it is designed in accordance with the principles of good corporate governance and legal compliance. Thus, marketing in the perspective of business law functions not only as a commercial tool but also as an instrument for creating legitimate, ethical, and equitable value for both the company and society.

Health problems in older adults, particularly oral function disorders, often lead to serious complications such as chewing difficulties, which disrupt adequate nutritional intake and may trigger broader health issues including malnutrition, aspiration pneumonia, and a decline in overall quality of life. One intervention that has been introduced to address these challenges is the PATAKARA exercise, a simple oral rehabilitation technique designed to strengthen oral and facial muscles. This study aimed to analyze the effect of PATAKARA exercise on the oral function of older adults at Roujin Home Seseragi No Sato Zao, Japan. The research employed a quasi-experimental approach with a One Group Pretest-Post Test Design. The study population consisted of 75 older adults, with 40 participants selected through purposive sampling. Data were collected using the Oral Health Impact Profile-14 (OHIP-14) questionnaire and analyzed with the Wilcoxon test. Findings showed that most participants were in the advanced elderly category (≥80 years), predominantly female, and had a secondary education background. Prior to the intervention, the majority exhibited moderate oral function, while after the exercise, most participants demonstrated improved oral function categorized as good. Statistical analysis revealed a significant effect of the PATAKARA exercise on oral function (p = 0.000). The results suggest that PATAKARA exercise effectively enhances oral muscle strength, including the lips, tongue, pharynx, and larynx, thereby improving chewing, swallowing, and speech functions. This exercise can be recommended as a practical, non-invasive, and low-cost intervention to support oral health and overall well-being among older adults.

This study aims to reveal the representation of adolescents’ emotional crisis in the music video 0X1=LOVESONG (I Know I Love You) by the South Korean boy group TOMORROW X TOGETHER. Using Roland Barthes’ semiotic approach, the research analyzes the denotative, connotative, and mythical meanings of the visual elements presented in the music video. The main focus is on how emotional crises such as loneliness, instability, alienation, and inner escape are represented through visual symbols such as a dark and messy room, a burning car, and a character standing alone in an open field. The research employed a qualitative descriptive method with a critical paradigm, analyzing eight key scenes in the music video that most strongly depict emotional struggles. The scenes were selected based on their symbolic intensity and relevance to adolescent psychological issues. Data analysis was conducted by interpreting visual signs through Barthes’ concepts of denotation, connotation, and myth. The findings reveal that the music video symbolically narrates the psychological struggles of adolescents who are not only physically isolated but also emotionally detached. The visual symbols construct new meanings that represent the social reality of modern youth, burdened by environmental pressures, societal expectations, and the quest for self-identity. Through the myths it creates, the music video functions not only as a medium of entertainment but also as a reflection and critique of adolescents’ psychological vulnerability. Thus, this study contributes to the understanding of emotional representation in popular media, particularly in audio-visual forms such as music videos, while enriching perspectives on how media constructs the narrative of adolescent emotional crises.

This study aims to describe the form and function of negation elements in the syntactic structure of Chairil Anwar's poetry anthology. The research method is descriptive qualitative with linguistic approach. The data sources are poetry texts by Chairil Anwar consisting of nine titles of Chairil Anwar's poems: Aku, Diponegoro, Karawang-Bekasi, Derai-Derai Cemara, Senja di Pelabuhan Kecil, Cintaku Jauh di Pulau, Hampa, Tak Sepadan and Siap Sedia. The data was collected using the documentation method, namely reading and scrutinizing the poetry texts to identify sentences that contain negation elements. The data found were then recorded and classified based on the form and location of the negation element in the syntactic structure of the sentence. Data analysis was conducted through several stages, namely: 1) identifying negation elements (all word/phrase elements containing negation elements in the poem); 2) classifying negation forms based on their types such as not, not, none, yet or don't; 3) analyzing syntactic structure (how the negation element functions in the syntactic structure, whether in predicate, subject, object or adverb; 4) interpreting the meaning and semantic and stylistic functions of negation elements in the context of the whole poem. To maintain data validity, this research uses theoretical triangulation by referring to various linguistic references (especially syntax and semantics) as well as previous studies on Chairil Anwar's poetry. In addition, data validation is done through cross-checking between readers on the results of identification and analysis. The results show that the element of negation plays a central role in shaping the syntactic structure, meaning and ideological and emotional character of his poetry. 

This study provides an in-depth examination of the emergence of servitude rights (hak servituut) arising from procedural errors in land parcel division, which result in landlocked plots without road access. Servitude rights, as regulated in Article 674 of the Indonesian Civil Code and reinforced by the Conversion Provision of Article I point 6 of the Basic Agrarian Law (UUPA), constitute a legal burden imposed on one parcel of land for the benefit of another, thereby ensuring that landlocked owners gain reasonable access. Although the UUPA serves as the national agrarian framework, the servitude concept remains highly relevant and functions as a crucial legal instrument to safeguard the rights of affected landowners. This research employs a normative juridical approach, integrating statutory and conceptual analyses to explore the consistency between legal theory and practice. The findings demonstrate that parcel division conducted without considering the social function of land, as mandated by Article 6 of the UUPA, can trigger access disputes that adversely affect community interests. Dispute resolution may proceed through litigation or non-litigation channels, with mediation emerging as the more effective and efficient option for maintaining harmonious relations between parties. Article 667 of the Civil Code provides a clear legal basis for landlocked property owners to obtain access while obligating them to pay fair compensation to the burdened land. Based on these findings, the study recommends strict adherence to lawful land division procedures and the development of detailed technical guidelines on servitude compensation to prevent future disputes and to strengthen legal certainty for all stakeholders.

Floods are the most frequent natural disasters and cause material and non-material losses. One of the problems faced is the lack of early warning when floods occur. This problem can be overcome with a flood early warning system. This paper discusses the solution to this problem, namely by designing and implementing a real-time flood early warning system using IoT-based Internet of Things (IoT) technology ESP32 MQTT and APK Kodular. The objective of this research, compared to previous studies, shows a gap in the methods used. While previous studies used an IoT-based flood warning system that sends data via SMS or an HTTP server, this study applies real-time monitoring with the MQTT protocol, which allows sending water level data with low latency to the Kodular application for faster and more responsive warnings. The method used is to connect hardware with IoT where ESP32 is a client that sends data to MQTT and will display it in the Kodular APK. This flood early warning system consists of: ultrasonic sensors, ESP32, MQTT cloud, OLED, buzzer, LED, and APK on the phone to receive notifications through a mobile application created using Kodular. This IoT-based system is installed in the Kudu Regency river and can monitor water levels in real-time. Based on a predetermined threshold, the system can activate the LED indicator or buzzer and send an early warning message to the user via the APK on the phone. Test results show that this system functions effectively in providing flood warnings with an accuracy of 1-2 cm and in a timely manner, making it suitable for community-based flood monitoring solutions

The presence of colloquial expressions in public signage commonly referred to ba- hasa gaul has increasingly become a linguistic hallmark in various tourism and recreational ar- eas in Indonesia. This study investigates the use of informal language on public signage at Pantai Kelan, Bali, and analyzes such linguistic choices that reflect social dynamics, youth identity, and evolving modes of communication in public space. Grounded in sociolinguistic perspectives, the research highlights the role of signage as not only a medium of information, but also a space for constructing shared meaning and fostering engagement through culturally resonant expressions. This qualitative research employed observational and documentation methods. It focused on twelve public signs installed at Pantai Kelan. Data were collected through field observations, photographic documentation, and subsequent transcription and analysis of the linguistic forms. The analysis fo- cused on identifying dominant lexical patterns, stylistic choices, and communicative functions of the language used. The signs were then interpreted with reference to their potential cultural, social, and interactional implications within the broader framework of linguistic landscape studies. The findings indicate that the use of bahasa gaul in signage serves multiple purposes: capturing atten- tion, expressing local identity, evoking humor, and connecting with a predominantly young and digital-native audience. Rather than being perceived as informal or inappropriate, such language use contributes to the effectiveness of public communication in specific contexts. The study con- tributes to the growing body of literature on language in public space and emphasizes the impor- tance of cultural relevance and sociolinguistic awareness in designing public signage that is both meaningful and impactful

Community service (PKM) is one of the pillars of the Tri Dharma of Higher Education, aimed at improving the quality of life of society through the transfer of knowledge and technology. This study focuses on the strategic role of PKM in addressing the low literacy levels in Indonesia, an issue that directly impacts social-economic welfare. Based on literature studies, this article analyzes the relationship between PKM, literacy, and welfare, as well as identifying effective implementation methods. The analysis results show that PKM is not only limited to formal education but must also be solution-oriented, participatory, and sustainable. Relevant PKM programs, such as the establishment of reading gardens, digital training for MSMEs, and financial education, have proven effective in enhancing community literacy. Improving literacy, including digital and financial literacy, is an essential tool for empowering communities to access information, develop skills, and make informed decisions. Digital literacy, for instance, opens access to vast information, while financial literacy helps communities manage their finances wisely, ultimately increasing their economic competitiveness. Through a participatory approach, PKM can also encourage communities to be more actively involved in decision-making processes related to their welfare. Through PKM programs, academics can bridge the knowledge and skills gap in society, contributing to the reduction of poverty and inequality. Thus, literacy not only functions to enhance individual capacity but also serves as a bridge to better welfare, covering economic, social, and health aspects. Solution-oriented and sustainable PKM programs can be the key to creating a more prosperous and independent society.

Leadership is not just about being a leader within an organization. It requires effective communication strategies and approaches. However, leadership changes when there are weaknesses in implementing communication methods with the team. Internal conflict, pressure from leaders, leadership style, and a leader's personality in facing challenges and problems are all factors. The purpose of this study is to deeply understand the relationship between leadership, emotional intelligence, and performance in an organizational context through a qualitative approach. The research method is derived from references in books and journals related to the topic under study. This study explores how leadership styles, interact with dimensions of emotional intelligence, including self-awareness, self-regulation, empathy, intrinsic motivation, and social skills, to influence individual and team performance. The study found that leaders with high emotional intelligence tend to implement an adaptive and inclusive leadership approach, create a conducive work climate, strengthen trust, and increase member engagement and productivity. The findings also reveal that emotional intelligence is not merely a supporting competency but also functions as a critical moderator of leadership effectiveness in achieving performance. This research provides theoretical contributions by enriching a holistic understanding of the psychosocial dynamics of leadership, as well as practical implications for the development of emotional intelligence-based leadership training programs through detailed quantitative and object-based research.

This study aims to analyze the effectiveness of zakat in reducing income inequality in Indonesia. The data used is secondary data from the National Amil Zakat Agency (BAZNAS) and the Central Statistics Agency (BPS) for the 2015–2024 period. The research method used multiple linear regression with the Ordinary Least Squares (OLS) approach. The results showed that the distribution of zakat had a significant positive effect on the Gini Index (β = 0.0013511; p = 0.002), while the Gross Domestic Product (GDP) per capita had a significant negative effect (β = –0.0000198; p = 0.000). An Adjusted R² value of 0.91 indicates that the model has a very strong ability to explain variations in income inequality. These findings show that although the collection and distribution of zakat has increased from year to year, its impact on reducing inequality has not been optimal. This can be caused by the limited amount of zakat funds collected compared to the real needs of the community and the distribution that is not fully on target. On the other hand, economic growth reflected in the increase in GDP per capita has proven to be still the dominant factor in reducing income inequality in Indonesia. The implications of this study emphasize the importance of optimizing zakat management so that it not only functions as a philanthropic instrument, but also as a sustainable economic instrument. BAZNAS and related institutions are expected to be able to strengthen the zakat distribution system through productive economic empowerment programs, so that zakat can make a real contribution in reducing inequality and supporting more inclusive development in Indonesia.
