The results show that Ayam Napinadar has a unique characteristic in the use of andaliman and blood (gota) as its distinctive flavor. Traditionally, the cooking process involves grilling over firewood to produce a characteristic smoky aroma, although it has now shifted to more practical methods without altering the original recipe. From a cultural perspective, Ayam Napinadar holds symbolic meaning as an expression of prayers, blessings, and joy in various Batak traditional ceremonies. However, there are challenges in its preservation, such as the declining participation of younger generations in traditional activities and the increasing influence of modern foods. In conclusion, Ayam Napinadar functions not only as food but also as a medium for preserving cultural values and ethnic identity. This study provides benefits as a basis for developing gastronomic tourism and strategies for preserving traditional cuisine through education, collaboration, and the use of modern promotional media.

Generators are one of the important auxiliary aircraft needed on ships for power generation. During the operation of a diesel generator, continuous rotation occurs resulting in friction and erosion of the moving parts. The supporting factor for the smooth running of a diesel engine is a lubrication system that is supported by good lubricating oil quality, besides that it also needs to be supported by an adequate and good cooling system. The use of lubricants is one of the most important factors to ensure the performance of diesel engines. The lubricant is in charge of maintaining the condition of the engine so that it remains stable. This study aims to analyze the effect of using lubricating oil beyond the operating hours limit on engine heat. Furthermore, it also discusses steps to ensure diesel engine temperatures remain normal. This research was carried out during the practice of sailing on a ship for approximately one year. This study uses a descriptive quantitative research method. The primary data obtained directly utilizes observation methods, and documentation. Secondary data was obtained from existing articles and journals. The data analysis techniques used are descriptive analysis and inferential analysis. The results of this study show that the working hours of lubricating oil use have a significant influence on the increase in the temperature of diesel generator engines as evidenced by hypothesis tests on two engine units, namely AE1 and AE2. In the AE1 unit, a t-value of 18.467 with a significance of 0.000 was obtained, while in AE2 the t-value was 14.289 with a significance of 0.000. The significance value in both units is less than 0.05 so it can be concluded that the working hours of lubricated oil have a significant influence on the temperature of the genarato diesel engine on the ship.

Population growth and socio-economic activities increase traffic volume, affecting the performance of the Raden Kusno – A. Djaelani – Sujarwo signalized intersection. This study aims to analyze the intersection’s current performance, estimate its condition over the next five years, and formulate alternative treatment strategies. The research data include geometric characteristics, signal timing, vehicle speed, and traffic volume obtained from CCTV recording over a three-day observation period from moning to evening, as well as population and vehicle data for projection. The intersection performance was analyzed using the PKJI 2023 approach and VISSIM simulation. Under current conditions, the intersection operates at LOS E with delays of 45,12 seconds (PKJI 2023) dan 60,56 seconds (VISSIM). In the five-year projection, delays increase to 48,97 seconds with LOS E (PKJI 2023) and 131,29 seconds with LOS F (VISSIM). Modifying the signal from four to three phases with a 70-second cycle improves the current condition to LOS C, with delays of 24,50 seconds (PKJI 2023) and 29,43 seconds (VISSIM). For the five-year projection, adding a continuous left-turn lane results in LOS D with 27,04 seconds (PKJI 2023) and LOS C with 32,01 seconds (VISSIM).

Human resource management (HRM) plays a crucial role in improving the quality of da’wah programs in mosques. This study aims to analyze the implementation of HRM in managing da’wah programs at Masjid Raya Pematang Siantar, as well as to identify obstacles and solutions to improve the effectiveness of da’wah activities. The research used a qualitative approach with interview, observation, and documentation techniques. Informants consisted of mosque administrators, preachers (da’i), and active congregants. The results showed that HRM in the da’wah programs already has a fairly clear organizational structure, but several aspects still need improvement. The recruitment of preachers is still conducted informally without clear competency standards, and there are no specialized training programs for preachers. Congregational participation also remains fluctuating. Another weakness is the minimal use of technology in disseminating da’wah information, as promotion is still carried out conventionally without optimizing digital platforms. In addition, limited funding and the lack of professional management personnel are major challenges. Solutions that can be implemented include improving preacher recruitment and training systems, utilizing technology in da’wah dissemination, and optimizing financial management through effective fundraising strategies. With better HRM implementation, da’wah programs at Masjid Raya Pematang Siantar are expected to operate more professionally and provide broader positive impacts on society

This study aims to analyze the symbolic meaning of the mangulosi tradition in Toba Batak traditional wedding ceremonies using Roland Barthes’ semiotic theory. This research employs a descriptive qualitative method, with data collected from visual media such as YouTube and TikTok, supported by informants familiar with Toba Batak culture. The findings reveal that meaning in the mangulosi tradition is constructed through three levels of signification: denotation, connotation, and myth. At the denotative level, mangulosi is understood as the act of giving ulos in a wedding ceremony. At the connotative level, ulos and the ritual process convey symbolic meanings such as blessings, protection, harmony, and the strengthening of social and kinship relationships. At the myth level, the tradition reinforces the cultural ideology that marriage is considered legitimate when it receives recognition and blessings from family and customary authorities. Quantitatively, the findings show that artifacts are dominated by visual connotative meanings (40%), while ritual actions emphasize non-verbal (30%) and verbal (20%) meanings. Therefore, the mangulosi tradition is not only a ceremonial practice but also a medium for preserving cultural identity and social values within the Toba Batak community.

Money laundering is a derivative crime that is frequently associated with corruption and has the potential to cause significant losses to state finances. Efforts to recover assets derived from criminal activities constitute an essential aspect of law enforcement aimed at restoring state losses and creating a deterrent effect for perpetrators. This study aims to analyze the authority of public prosecutors in the investigation of money laundering crimes as well as the mechanisms for state asset recovery based on the authority of the Indonesian Attorney General’s Office. The research method employed is normative juridical research using statutory and case approaches. The results of this study indicate that the Attorney General’s Office possesses clear and legally valid authority to conduct investigations into money laundering crimes as regulated under Law Number 8 of 2010 concerning the Prevention and Eradication of Money Laundering and the Law on the Attorney General’s Office. Prosecutors are authorized to trace, seize, confiscate, and recover assets derived from criminal acts without first proving the predicate offense. This study further emphasizes that although the authority of the Attorney General’s Office has been normatively regulated, in practice, state asset recovery continues to face various obstacles, both in substantive and procedural law, such as inconsistencies in statutory regulations and the suboptimal implementation of non-conviction-based asset forfeiture. Therefore, strengthening regulations and harmonizing legal policies are necessary to ensure that state asset recovery through the handling of money laundering crimes can be carried out more effectively and provide legal certainty.

This study aims to develop a storytelling-based learning media in the form of a YouTube video to support students’ understanding of narrative text based on their learning needs. This study employed a Research and Development (R&D) design using the ADDIE model, focusing on the stages of analysis and development. The data were collected through a questionnaire as part of the needs analysis to identify students’ responses toward listening and repetition activities, as well as the difficulties they face in understanding narrative texts. The results show that students generally respond positively to listening and repetition. However, they still experience difficulties in understanding the storyline and vocabulary. The findings also indicate that students need learning support in the form of audio, visual elements, and vocabulary assistance. Based on these findings, a learning product was developed in the form of a YouTube-based digital storytelling video entitled “Learn Narrative Text Through Fun Storytelling (Listen, Repeat & Retell)”. The video integrates storytelling, repetition, vocabulary explanation, and speaking practice to support students’ comprehension. Due to time limitations, this study was limited to the development of a prototype and has not yet included expert validation. Therefore, future research is recommended to conduct validation to evaluate the feasibility and effectiveness of the developed product.

As the foundation and official ideology of the Indonesian state, Pancasila plays a crucial role in guiding the management of national affairs and the overall conduct of state life. The core principles of Pancasila divinity, humanism, unity, democracy, and social justice reflect the character, identity, and collective values of the diverse Indonesian people. The purpose of this study is to examine in depth the function of Pancasila as a state ideology and the significance of implementing its principles in contemporary and evolving society. Through the exploration and analysis of various scholarly sources, including books, academic journals, and official state documents, this research employs a qualitative approach using a literature review method. The findings indicate that Pancasila functions not only as the nation’s way of life but also as the philosophical foundation of the state and a unifying ideology within Indonesia’s heterogeneous society. Furthermore, the preservation of national identity, the strengthening of social cohesion and peace, and the ability to face the challenges of industrialization and globalization are highly dependent on the successful internalization of Pancasila’s values. Therefore, to achieve sustainable and inclusive national development, consistent and continuous efforts are required to enhance understanding, appreciation, and implementation of Pancasila’s values across all levels of society.

This study explores how social media–driven green marketing shapes sustainable consumer behavior through a systematic literature review. As concerns about sustainability intensify alongside rapid digital engagement, social media has emerged as a crucial platform for communicating environmental initiatives and influencing consumer responses. Despite this relevance, existing studies remain fragmented across theoretical, contextual, and methodological perspectives, limiting a holistic understanding of the topic. Using the PRISMA approach, this research reviews 42 empirical articles sourced from the Scopus database and analyzes them through the TCCM (Theory–Context–Characteristics–Method) framework. The findings show that most studies rely on intention-based theories, particularly the Theory of Planned Behavior, although there is a growing shift toward integrating social, psychological, and technology-oriented approaches. From a contextual standpoint, the literature is largely concentrated in Asian regions and younger demographics, which restricts broader generalization. Furthermore, results indicate that social media–driven green marketing does not directly affect sustainable behavior but works through important psychological mediators such as trust, engagement, and perceived value. These factors significantly influence how consumers interpret and respond to environmental messages online. The effectiveness of such marketing strategies is also shaped by cultural and demographic differences, making context a critical factor. Methodologically, most studies employ cross-sectional surveys and structural equation modeling, limiting the ability to capture causal and dynamic relationships. Overall, this study provides a structured synthesis, highlights research gaps, and suggests future directions, including cross-cultural analysis, stronger theoretical integration, and more rigorous research designs.
