Conflict is an inevitable phenomenon in every organization, whether in business, education, or social contexts. If not managed properly, conflict has the potential to reduce performance; however, if handled constructively, it can become a source of innovation. Based on this issue, this study aims to answer the main question: how is conflict understood and managed according to recent literature findings? The method used is a literature review by searching for articles through several online databases using the keywords "organizational conflict," "conflict management," "types of conflict," and "resolution strategies." From an initial search result of 17 articles, after a screening process, 15 articles met the criteria for further analysis. The analysis results reveal three main themes. First, conflict in organizations can be categorized into several types, such as intrapersonal, interpersonal, intragroup, and intergroup conflicts. Second, the sources of conflict often stem from differences in interests, ineffective communication, and unequal distribution of resources. Third, conflict resolution strategies vary, including mediation, collaborative communication, compromise, deliberation, and approaches based on religious values.

This research aims to understand how the meaning of loss is constructed in the lyrics of the song “Cutting My Fingers Off” by Turnover, using Ferdinand de Saussure’s semiotic approach. The song was chosen as the object of study because it expresses the emotion of loss intensely through poetic and emotional lyrical symbols. According to Saussure’s theory, meaning is formed through the relationship between the signifier and the signified, where words in the lyrics function as signs that carry deep meaning. This study uses a descriptive qualitative method with interview, textual analysis techniques, supported by literature review and observation of listener Turnover’s “Cutting My Fingers Off”. The analysis involves breaking down each verse to identify signifiers and signifieds that shape the emotional meaning of loss. The findings show that the lyrics reflect not only physical loss but also psychological experiences such as alienation, regret, and severed emotional attachment. Symbols like “Cutting My Fingers Off” form a visual metaphor for deep emotional pain. This research concludes that music particularly lyrics is an effective medium of symbolic communication to convey personal experiences. “Cutting My Fingers Off” successfully constructs a complex meaning of loss that resonates personally with its listeners.

This success proves the effectiveness of mind mapping as a pedagogical tool for transforming ICT learning into a more active, visual, and structured experience.

Clean water is a fundamental necessity; however, many regions still struggle to access it due to contamination by suspended particles, organic matter, and harmful microorganisms. This activity aims to strengthen the practical competence of Biology Education students at Universitas Negeri Medan through training in making simple water filters. The training was conducted through demonstrations and simulations using turbid water from the Tembung River as a sample. The filter was constructed from readily available materials such as used plastic bottles, cotton, tissue, sand, small gravel, and palm fiber arranged in layers. The results showed that the filter effectively reduced water turbidity and enhanced students’ skills in clean water treatment technology. The training also encouraged students to develop 21st-century skills such as critical thinking, problem-solving, and collaboration, while preparing them as future educators capable of raising community awareness about the importance of maintaining water quality. Therefore, this training has the potential to be developed as an applicative environmental education model that contributes positively to clean water provision.

This study investigates the occurrence and functions of nonstandard language variation in Instagram headlines posted by @folkative, a popular digital media account known for its creative use of informal language. Despite the growing attention to social media discourse, little research has focused on how nonstandard forms operate in short, attention-grabbing digital headlines. Guided by Labov’s (1972) variationist sociolinguistic framework, this study employs a descriptive qualitative method complemented by simple quantification. The data consist of headlines uploaded by @folkative throughout September 2025. The analysis reveals four main types of nonstandard variation: code-mixing, nonstandard spelling, colloquial expressions, and lexical innovation. Among these, code-mixing appears most frequently (33.93%). The use of nonstandard language is not arbitrary but rather reflects deliberate stylistic and social choices. These variations serve several communicative and pragmatic functions, including attracting readers’ attention, conveying humor, saving space within limited character counts, expressing solidarity with followers, and constructing a modern, cosmopolitan online identity. The findings demonstrate that nonstandard language in Instagram headlines contributes to meaning-making and audience engagement, showing how Indonesian users creatively manipulate linguistic resources to suit digital communication norms.

Therefore, the results of this study, namely the Hanasui live feature on Shopee, show that Scarcity and Urgency play a role in consumer purchasing decisions.

An exhaust pipe is a tubular device used to channel combustion gases from a vehicle’s engine into the environment. In addition to this primary function, the exhaust also serves to reduce the noise level produced by engine combustion. The component of the exhaust system that significantly affects torque, brake mean effective pressure (BMEP), and noise level is the silencer. This study aims to compare the torque, BMEP, and noise levels produced by variations in the length and construction dimensions of elliptical filter designs in the silencer. The silencers used in this research have lengths of 280 mm, 300 mm, and 260 mm, with short ellipse filter diameters of 25 mm and long ellipse filter diameters of 30 mm, 40 mm, and 50 mm. The research employs an experimental quantitative method, and the data were analyzed using one-way Analysis of Variance (ANOVA). The experiment was conducted in a Mechanical Engineering workshop using a Yamaha R15 V3 155cc injection motorcycle (2021), a Super Dyno 50L dyno test, and a sound level meter, from February to April 2024. The engine speeds tested were 1500, 2500, 3500, 4500, 5500, and 6500 rpm. The results show that the variation of ellipse dimensions 25 mm × 50 mm × 260 mm produced a maximum torque of 12.77 N·m at 4500 rpm, a maximum BMEP of 1021 kPa at 4500 rpm, and a noise level of 80.3 dB. The variation 25 mm × 40 mm × 300 mm produced a maximum torque of 12.88 N·m, a BMEP of 1042 kPa, and a noise level of 75.60 dB, while the variation 25 mm × 30 mm × 280 mm produced a maximum torque of 12.67 N·m, a BMEP of 1013 kPa, and a noise level of 75.63 dB.

Real Analysis is a fundamental course in mathematics education characterized by its deductive and axiomatic structure, which requires logical, systematic, and conceptual understanding. However, many studies have shown that students often face difficulties in grasping abstract concepts and constructing mathematical proofs deductively. Lestari (2015) found that most students were only able to conduct proofs inductively, while their deductive proof skills remained low due to weak prerequisite knowledge and lack of formal reasoning practice. Meanwhile, Darmadi, Sanusi, and Rifai (2024) explained that students’ difficulties in understanding formal definitions and the structure of real numbers indicate the need for a learning approach that emphasizes conceptual comprehension. This article employs a literature review approach to analyze the application of conceptual approaches in helping beginners understand Real Analysis. The results show that a conceptual approach enhances students’ understanding of the meaning behind mathematical symbols and procedures, helps them build connections among concepts such as limits, continuity, and the real number system, and gradually develops their deductive reasoning skills. Therefore, applying a conceptual approach in Real Analysis learning is an essential strategy to help students achieve deep, logical, and meaningful understanding.

In German language courses at universities, students must learn four skills: reading, writing, listening, and speaking. To master these four skills, students must have a good command of vocabulary, as this is the foundation needed to master the German language. This software does not require programming code, so users can easily add graphics and sounds to the game. Without vocabulary, skills such as reading, writing, speaking, and listening cannot be performed. This study aims to create a Construct 2 application that can be used by college students to increase their A1 level German vocabulary. The data for this study is A1 level German vocabulary with the theme “Guten Appetit,” and another source of data is the book “Netzwerk neu A1 Kursbuch” published by Ernst Klett Sprachen GmbH in 2019. This research will be conducted in the foreign language laboratory at UNIMED. The application will be tested by subject matter experts and learning media experts. This research will be published in a nationally indexed journal.

This research aims to examine how betrayal is represented in the film The Last Supper (2025). The study employs a qualitative approach using John Fiske’s semiotic theory, which focuses on three levels of codes: reality, representation, and ideology. Data were collected through visual observation of the film’s scenes and analyzed to identify signs and underlying meanings within the actions of the characters. The findings reveal a total of nine betrayal scenes, segmented into 52 image shots that were analyzed in depth. These scenes primarily depict the betrayals committed by Judas Iscariot and Peter against Jesus Christ. The analysis shows that betrayal is not merely presented as a dramatic motif but is constructed as an ideological representation that reflects power relations, social pressure, and human moral dilemmas. The film serves as a cultural text that constructs meaning through visual symbols, gestures, expressions, and dialogue. As such, it can be interpreted as a form of social criticism against systems of power that influence individual behavior. Therefore, the film functions not only as entertainment but also as a discursive space that voices fundamental human issues.

Conflict is an inevitable phenomenon in organizations and educational institutions, and if not managed properly can have a negative impact on performance, effectiveness, and interpersonal relationships. However, conflict also has the potential to be a catalyst for improvement if managed appropriately. Therefore, it is important to systematically examine the stages of conflict, their impacts, and relevant management strategies. This study aims to answer the following questions: (1) How are the stages of conflict identified in various organizational and educational contexts? (2) What are the impacts of conflict on organizations? and (3) What management strategies are most effectively implemented? The method used was a literature review by searching articles through national and international databases using the keywords stages of conflict, conflict management, and education. Of the 73 initial articles, 18 primary articles were selected for thematic analysis. The analysis revealed three main findings: (1) conflict generally develops through stages of latency, escalation, and overt manifestation; (2) conflict negatively impacts performance if left unchecked, but can be constructive if managed; and (3) effective conflict management strategies are contextual, combining structural, interpersonal, and cultural-religious value approaches. In conclusion, this literature highlights the need for adaptive conflict management to maintain organizational stability. Further research is suggested to explore integrative models of conflict management based on local values and educational practices.

This study explores the practice of participatory communication and creative production implemented by the Anggrek Waste Bank along the Ciliwung River as an educational strategy for flood disaster mitigation. The research aims to understand how community-based waste management initiatives can serve as platforms for environmental learning and social empowerment. Using a qualitative approach with a case study method, this study investigates social dynamics, interaction patterns, and meanings constructed by residents through collaborative waste management and creative production activities. Data were collected through observation, in-depth interviews, and documentation. The findings reveal that participatory communication is manifested not only in formal education, counseling, or campaigns, but also in everyday interactions, creative workshops, and collective community work. Creative products such as recycled crafts, soap made from used cooking oil, and eco enzymes function as symbolic communication media that persuasively convey ecological messages while providing tangible economic benefits. These practices foster a sense of ecological responsibility, strengthen social solidarity, and enhance community resilience to flooding. This study concludes that participatory communication integrated with creative production serves as an effective model for promoting sustainable behavior and community-based flood mitigation in urban environments.

This study aims to analyze junior high school students’ mathematical reasoning abilities in terms of their levels of learning independence. The research employed a descriptive qualitative approach involving three ninth-grade students from UPT SMP Negeri 5 Gresik, each representing high, medium, and low levels of learning independence. Data were collected through a self-regulated learning questionnaire, a mathematical reasoning test based on the topic of Systems of Linear Equations in Two Variables (SPLDV), and semi-structured interviews. Data analysis followed Miles and Huberman’s interactive model, consisting of data reduction, data display, and conclusion drawing. The results revealed that students with high learning independence demonstrated strong reasoning skills across all seven indicators of mathematical reasoning (representing statements, making conjectures, performing manipulations, constructing proofs, drawing conclusions, verifying arguments, and identifying patterns). Students with medium learning independence fulfilled only some indicators, while those with low learning independence could only make simple conjectures without systematic reasoning. These findings highlight that learning independence plays a crucial role in developing mathematical reasoning, as it enables students to regulate their thinking processes, evaluate solutions, and correct errors. Teachers are encouraged to integrate learning strategies that foster self-regulation—such as the CORE and Flipped Classroom models—to enhance students’ mathematical reasoning skills.

In the digital era, YouTube has become a powerful platform for sharing knowledge, shaping perspectives, and encouraging critical engagement. This study explores how multimodal elements—verbal, visual, and audio—construct meaning in the educational video “Kalau Kamu Mau Punya Critical Thinking, Jangan Skip Obrolan Ini!” from the Suara Berkelas channel. Using a qualitative case study approach, the research interprets how these modes work together to support critical thinking. Data were collected through video observation, transcription, and documentation of multimodal features, then analyzed thematically using Kress and van Leeuwen’s multimodal framework and Facione’s critical thinking model. The findings show that the verbal mode structures logical arguments and rhetorical appeals, the visual mode emphasizes meaning through gestures, expressions, and text overlays, while the audio mode builds emotional engagement through tone, pauses, and background music. Together, these modes create a coherent and persuasive discourse that not only informs but also invites viewers to reflect critically. The study contributes theoretically to the understanding of multimodality in digital education and practically provides insights for educators and content creators to design more interactive, reflective, and engaging educational content.

This research explores the dual impact of Artificial Intelligence (AI) on the academic writing experiences of English Literature students learning English as a Foreign Language (EFL). AI tools like ChatGPT, Grammarly, and QuillBot are commonly used for grammar correction and sentence construction. These tools are integrated into students' writing processes, providing valuable assistance in refining their written work. However, their psychological effects, particularly in terms of emotional and ethical implications, have not been sufficiently explored in previous research. This study employed a qualitative phenomenological approach, utilizing Interpretative Phenomenological Analysis (IPA), to examine the experiences of ten final-year EFL students who actively use AI tools for academic writing. Through semi-structured interviews, the research identified three major themes: reduced technical stress, heightened dependency on AI tools, and ethical concerns about authorship. The findings suggest that while AI tools act as cognitive scaffolds, aiding students by improving fluency and reducing the burden of technical writing tasks, they also introduce psychological challenges. These challenges include increased dependency on the tools and concerns about the authenticity of their work, raising questions about academic integrity and self-efficacy. This study sheds light on the complex relationship between AI as an assistive technology and its potential to cause writing anxiety and dependency. By emphasizing both the positive and negative psychological impacts of AI, the study contributes to the growing body of literature on AI in education. It calls for the development of pedagogical frameworks that balance AI literacy, emotional resilience, and ethical considerations to ensure responsible and effective use of AI in academic contexts.

This study aims to design a blanking die used for mass-producing mobile phone holders while prioritizing efficiency and dimensional accuracy. The die set developed includes key components such as the punch, die, stripper, guide post, and fastening bolts. The product produced has dimensions of 138 × 63 × 2 mm and uses ST 37 steel as the raw material. Based on calculations, the required blanking force is 129,000 kN, which is considered safe for the production process. The design also accounts for an optimal clearance of 0.083 mm and a die thickness of 35 mm to effectively withstand the working load. Simulations using stress analysis methods reveal that the von Mises stress distribution on both the punch and die remains below the elastic limit of SKD11 material. The maximum stress on the punch is recorded at 2.437 × 10⁵ N/m², while on the die it reaches 5.153 × 10⁵ N/m², both well below the yield strength of SKD11, which is 2.918 × 10⁸ N/m², indicating that these components operate safely without the risk of plastic deformation. To strengthen the construction, the stripper is designed with a thickness of 12 mm, and the addition of four SCM435 bolts is recommended to improve system stability. This die design is verified through manual calculations and Finite Element Analysis (FEA) to ensure its reliability. Overall, the findings of this study demonstrate that the designed blanking die can support mass production with high precision, optimal structural strength, and long-term durability.

So the specific objective of this community service is directed at constructing the management's understanding of entrepreneurial-based cooperative management which is derived to answer 3 (three) specific problems, namely: (1) what is meant by cooperative entrepreneurship towards prosperous members?; (2) why is cooperative entrepreneurship important for student cooperative managers towards prosperous members? and (3) how to internalize cooperative entrepreneurship in student cooperative managers towards prosperous members? The method used is Focus Group Discussion (FGD) with participants being the management of the Student Cooperative (Kopma) al-Kautsar UIN Sayyid Ali Rahmatullah Tulungagung. The results of the service show that Kopma members have the same insight in perceiving cooperative entrepreneurship, namely the entrepreneurial spirit of members. Entrepreneurial spirit is a member modality shown by the creativity and independence of members. Meanwhile, the strategy to internalize cooperative entrepreneurship is by translating cooperative values ​​reflected in a responsible attitude implemented in the form of an Annual Members Meeting (RAT).

The increasing demand for electrical energy and the issue of climate change are driving the utilization of renewable energy, one of which is through Solar Power Plants (PLTS). The Province of Bali targets the development of PLTS of 108.2 MW, equivalent to 8.62% of the total solar energy potential of 1,254 MW by 2025. However, land limitations pose an obstacle to the construction of large-scale PLTS. Floating solar power plant design can be a solution to this issue. By utilizing 4,955.32 m² of water surface at the Telaga Tunjung Dam, the Floating Solar Power Plant at Telaga Tunjung Dam has a potential capacity of 141.4 kWp, using 280 Trina Solar modules of type TSM-DEG18MC.20(II) (505 Wp) combined with one SG110CX inverter with a capacity of 110 kW. The annual electricity production of the floating solar power plant, based on Helioscope software, is 201.1 MWh. The economic feasibility parameters used in this study include initial investment cost, Profitability Index (PI), and Payback Period (PP). The analysis results show that the 141.4 kWp floating solar power plant project at Telaga Tunjung Dam has an initial investment value of IDR 1,248,764,582, a PI of 1.26, and a PP of 3.91 years. Therefore, this project is considered economically feasible and contributes positively to reducing CO₂ emissions.

This research is an empirical study that aims to examine the influence of a number of financial indicators on company value in the construction and building subsectors listed on the Indonesia Stock Exchange (IDX) during the 2019–2023 period. The indicators analyzed include profitability, free cash flow (FCF), and leverage. This study uses a purposive sampling approach involving 9 issuers and produces 45 observation data. The analysis method used is multiple linear regression to test the relationship between independent variables and company value as measured by Price to Book Value (PBV). The results of the study show that the performance of Return on Assets (ROA) as well as the Debt to Asset Ratio (DAR) and Debt to Equity Ratio (DER) ratios have a significant effect on increasing the company's value. In contrast, other indicators such as Net Profit Margin (NPM), Free Cash Flow (FCF), and Long-Term Debt to Equity Ratio (LTDtER) did not show a significant influence. These findings indicate that investors prioritize capital utilization efficiency and sound funding structures in assessing the value of a company, compared to free cash flow or net profit margins. This research provides important implications for company management and investors in formulating financial strategies that are oriented towards increasing the company's value in a sustainable manner.
