The increasingly complex global energy problem drives the need for efficient, low-cost, and environmentally friendly energy storage systems. This study aims to analyze the power performance of two symmetric supercapacitor prototypes using Nitrogen-doped Graphene-Like Carbon (N-GLC) as the electrode material and 1 M  as the electrolyte, with different electrode substrates: aluminum and copper. Both prototypes were tested through charging and discharging processes using resistive loads of 470 ohms and 560 ohms for 5 minutes. The analyzed parameters include voltage, current, power, and output energy. The results show that the aluminum electrode achieved a higher maximum charging power of up to 18 mW; however, its energy discharge efficiency was very low at only 0.87%. In contrast, the copper electrode demonstrated a more balanced charging and discharging performance with an energy discharge efficiency of 19.4%. Analysis also indicates that the copper substrate maintains better voltage stability after 6 hours of storage compared to aluminum, which experienced significant degradation. Thus, the copper electrode is superior in maintaining the power and stability of a simple N-GLC-based symmetric supercapacitor system.

This research aims to design and develop a prototype wave power plant that utilizes the vertical motion of a buoy as a source of mechanical energy, which is then converted into electrical energy using a recoil starter mechanism. The system is designed to be installed at the stern of a prototype ship. The vertical movement of the buoy caused by ocean waves is transmitted to the recoil starter through a drive rope, producing a stable one-way rotational motion. This rotation is further transmitted to a gearbox to increase rotational speed before driving a DC generator. The electrical energy generated is stored in a 12 VDC battery, supported by a buck–booster converter to stabilize the output voltage. This study employs an experimental engineering approach to evaluate system performance based on empirical test data. The main components of the system include a buoy as a wave energy collector, a recoil starter as the initial rotating mechanism, a DC generator as the electrical energy producer, a buck–booster converter as a voltage regulator, a 12 VDC battery as an energy storage unit, and a monitoring system based on an ESP32 microcontroller integrated with a PZEM-017 sensor. Experimental results show that the recoil starter operates effectively in driving the generator under both no- load and buoy-loaded conditions. Increases in generator rotational speed are directly proportional to increases in output voltage and current. The PZEM-017 sensor demonstrates a high level of measurement accuracy, approaching 100% when compared with a multimeter. Overall, the proposed wave power generation system functions reliably and shows potential for further development as a small-scale alternative renewable energy source.

The increasing demand for electrical energy and the limited availability of fossil fuels have driven the development of renewable energy sources, including marine current energy, which remains underutilized in coastal and remote maritime regions. This study presents the design and realization of a small-scale marine current power generation prototype using a horizontal axis propeller turbine with a NACA S814 blade profile and analyzes the effect of turbine rotational speed on electrical power output. The system converts marine current kinetic energy into mechanical energy through turbine rotation and subsequently into DC electrical energy using a generator, which is stabilized by a Buck–Boost Converter and Maximum Power Point Tracking (MPPT) for charging a 12 VDC battery. Real-time monitoring of electrical and mechanical parameters is implemented using an Internet of Things (IoT)–based system comprising an ESP32 microcontroller, a PZEM-017 sensor, and an RPM sensor. Experimental results demonstrate a positive correlation between water flow rate, turbine rotational speed, and generator output voltage. The system begins operating at a minimum flow rate of 35.2 L/s at 56 RPM, producing 0.2 V, while optimal performance is achieved at 45.3 L/s and 516 RPM, generating up to 13.3 V. These results indicate that the proposed prototype is a viable alternative renewable energy source for marine applications.

This article examines pneumatological methods and spiritual practices across three Pentecostal seasons: Classical Pentecostalism, Charismatic, and Neo-Charismatic. It highlights the importance of these three movements within the framework of the development of the Pentecostal-Charismatic Church in Indonesia. This research begins with the observation that scholars continue to use the terms Pentecostal, Charismatic, and Neo-Charismatic overlappingly, despite their unique theological and practical emphases. This article presents a critical-comparative literature review on baptism in the Holy Spirit, speaking in tongues and spiritual gifts, forms of spirituality, interdenominational relations, theological risks, and ecclesiological implications. The research finds that Classical Pentecostalism emphasizes baptism in the Holy Spirit and speaking in tongues as the primary evidence, Charismatics extend Spirit-led activities toward cross-denominational renewal, while Neo-Charismatics place additional emphasis on power, miracles, healing, spiritual warfare, and success in life. The contribution proposed in this article is a theological typology that can be used for critical reading of Pentecostal-Charismatic practices in Indonesia while still appreciating the richness of the experience of the Spirit. This typology can help churches consider experience, Scripture, Christian character, and ecclesiastical institutional accountability in a more balanced way.

This study was conducted to systematically explore the influence of the level of ease of transactions and the quality of e-commerce services on the process of determining consumer purchasing decisions in Batam City. The research framework was built with a descriptive-oriented quantitative approach through the involvement of 100 respondents who actively utilize digital transaction services, which were determined using a purposive sampling technique based on the Lemeshow formulation to ensure the adequacy and representativeness of the sample. Empirical data were collected through a structured questionnaire and then processed using statistical analysis stages that included testing the validity and reliability of the instrument, evaluation of classical assumptions, multiple linear regression modeling, and verification of hypotheses through t-tests and F-tests. The results of data processing revealed that the variable of ease of transactions contributed 18.8% to purchasing decisions, while service quality contributed an influence of 63.5%. The coefficient of determination (R²) reaching 73.3% indicates that both independent variables simultaneously have substantial explanatory power towards variations in consumer purchasing behavior. Both partial and simultaneous testing confirmed a significant influence, thus confirming that simplifying transaction mechanisms and strengthening digital service quality are strategic determinants in driving e-commerce consumer purchasing decisions in Batam City.

The shaft is a crucial component in mechanical systems because it serves to transfer power and rotational motion throughout the machine. This research aims to assess the structural strength and operational performance of shafts used in a tire shredding machine through numerical simulation methods in order to achieve a safe and efficient design. The study involved several stages, including the development of shaft geometry models, the determination of boundary conditions, load application, mesh generation, and stress analysis using the finite element method. Two shaft configurations were examined: a 59 mm diameter shaft made from AISI 1045 steel and a 49 mm diameter shaft manufactured from ASTM A36 steel. The simulation results indicate that the 59 mm shaft experiences a Von Mises stress of 8.9 × 10⁻⁵ MPa, with a maximum displacement of 0 mm and a safety factor of 15. Similarly, the 49 mm shaft shows a Von Mises stress of 8.4 × 10⁻⁵ MPa, no measurable displacement, and a safety factor of 15. These findings confirm that both shaft designs are capable of safely withstanding the applied working loads. In addition, cutting system tests revealed that a 24-tooth blade achieved an efficiency of 26.9%, while a 40-tooth blade reached only 22.3%, indicating that the 24-tooth configuration provides better performance.

Agrarian conflict is a common issue in development processes, particularly when changes in land ownership or control involve various interests. This study aims to analyze the dynamics of agrarian conflict in the coastal area of ​​Atapupu Beach, Jenilu Village, Kakuluk Mesak District, Belu Regency, triggered by the land acquisition process by the Defense University (UNHAN). The study used a qualitative approach with a case study method to understand the social conditions developing in the community. Data were obtained through in-depth interviews, field observations, and documentation. The results indicate that the conflict arose due to changes in community access to coastal areas previously used for economic activity. The presence of UNHAN has restricted community activities in the Fish Auction Place (TPI) area, previously a center for fishing activities. This situation has given rise to social tensions between the community and the area management. This study emphasizes that coastal area management needs to consider local community interests through a dialogical and participatory approach to minimize agrarian conflict.

This study aims to elaborate on the determinants of consumer purchasing decisions by emphasizing the role of social media, trust levels, and product quality in the Blibli e-commerce ecosystem in Batam City. The applied methodological framework is based on a descriptive quantitative approach involving 204 respondents with active transaction track records, selected through a purposive sampling technique based on the Jacob Cohen formula to ensure proportionality and validity of sample representation. Empirical data were collected through a structured questionnaire, then processed using comprehensive statistical analysis stages that include instrument validity and reliability testing, classical assumption evaluation, multiple linear regression modeling, and hypothesis testing through partial (t) and simultaneous (F) tests. The analysis results revealed that social media intensity contributed 14.1% to purchasing decisions, trust influenced 36.0%, while product quality influenced 40.4%. The coefficient of determination (R²) value of 86.4% indicates that the three exogenous variables simultaneously have substantial explanatory power towards variations in purchasing decisions. The t-test and F-test findings consistently confirm the significant influence of both individual and collective factors, thus confirming that strengthening digital presence, platform credibility, and consistent product quality are strategic foundations in guiding the preferences and purchasing intentions of Blibli consumers in Batam City.

This study aims to analyze the legal regulation of joint ventures in Indonesia as a form of Foreign Direct Investment (FDI) implemented through Limited Liability Companies based on Law Number 25 of 2007 concerning Investment, Law Number 40 of 2007 concerning Limited Liability Companies, and the Indonesian Civil Code. The research employs a normative legal method with a library research approach to examine legal provisions and concepts related to cooperation between foreign investors and domestic parties. The findings indicate the existence of structural imbalances between the parties, where foreign investors possess advantages in capital, technology, business experience, and access to information, resulting in asymmetrical bargaining power. This condition may lead to domination in decision-making, information gaps, and potential exploitation of domestic parties. Furthermore, existing legal protection is considered insufficient to fully implement the principle of equitable bargaining. Therefore, this study proposes a normative reconstruction through the application of principles of balance of power, good faith, transparency, and proportionality in joint venture agreements. The study also recommends preventive supervision through mandatory due diligence by the Financial Services Authority and the Investment Coordinating Board, including the standardization of contractual clauses and disclosure obligations, in order to create fair, sustainable joint venture relationships that protect national interests.

Syndicated credit serves as a response for banks in extending loans as an alternative financing mechanism when constrained by the legal lending limit. Syndicated loans have a distinctive characteristic, namely the requirement for collective decision-making among creditors to reach a resolution. Consequently, collateral execution is often delayed or not carried out optimally to recover bank receivables, resulting in participating banks bearing losses for a relatively long period. This research employs a normative juridical approach with descriptive-analytical research specifications using qualitative methods based on relevant legal norms and theories. The results show that the legal relationship between the bank agent and the syndicated creditors constitutes an agency relationship, namely a special power of attorney as regulated under the Civil Code. The Bank Agent, consisting of the Facility Agent, Security Agent, and Escrow Agent, acts according to their respective duties for the benefit of the syndicate within the scope of authority agreed upon in the credit agreement. The resolution of non-performing loans in syndicated credit schemes should be carried out by referring to credit rescue and settlement mechanisms as regulated in the OJK Regulation concerning the Asset Quality Assessment of Commercial Banks through the prudential principle. The legal liability of the Bank Agent or Security Agent arises only when it can be proven that the agent has acted beyond the authority granted to it.

The development of Pantai Indah Kapuk 2 (PIK 2) presents serious issues, including eviction, the loss of traditional livelihoods, and the marginalization of local communities within a modernization agenda that disregards social justice and sustainability. This research questions the extent to which the dominant modernization bias influences the socio-economic conditions of the surrounding community, as well as how public participation practices are implemented in the planning and execution of the project. The PIK 2 project has led to social inequality, the deprivation of rights, and environmental degradation, illustrating a pattern of systemic exploitation of coastal communities through the economic and political power of development elites. The dominant development theory framework proposed by Melkote and Steeves is used to examine modernization bias, supplemented by Islamic concepts such as mustadh’afin and ghasab to strengthen the social justice perspective. In this study, the author employs a qualitative case study approach, utilizing in-depth interviews, field observations, and documentation involving affected residents, community leaders, and policymakers. The results of the analysis indicate very low levels of public participation, instances of intimidation during land acquisition, and a significant loss of access to employment and basic facilities for the community. The conclusion of this research emphasizes the need for policy reform to ensure that development is more transparent, participatory, and equitable, in order to protect the rights of local communities from dominant and exploitative development patterns.

Environmental damage caused by human activities has become an increasingly pressing global issue. Poetry as a literary work has the power to represent ecological problems symbolically and critically. This study aims to describe the representation of the impact of the environmental crisis in Taufiq Ismail's poems, namely "Menengajah Ke Atas, Merenungi Ozone yang Tak terlihat" and "Membaca Tanda-Tanda." The analysis is based on Greg Garrard's ecocritical study. This study uses a qualitative method with content analysis techniques. There are two stages of analysis, namely the literal and symbolic meaning of the poems, then an ecocritical interpretation is carried out based on Garrard's categories which include pollution, wilderness, apocalypse, dwelling, animals, and earth. The results of the study indicate that both poems represent the impact of the environmental crisis through health problems due to pollution and radiation, damage to water and forest ecosystems, climate change, threats to human living space, and the decline in biodiversity. The research findings also show that the most dominant categories are pollution and apocalypse, which confirms that the environmental crisis in Taufiq Ismail's poems is the result of human behavior that ignores nature. Thus, Taufiq Ismail's poems not only function as aesthetic works, but also as cultural criticism and moral warnings for humanity.

This study was motivated by students’ low conceptual understanding of temperature, heat, and thermal expansion at SMP Negeri 28 Batanghari, where learning achievement remained below 50%. Instruction predominantly used PowerPoint-based media, resulting in passive learning and limited contextual engagement. This study aimed to develop web-based interactive multimedia (GlidesApps) integrated with Cepak Kapung ethnoscience that is valid, practical, and effective in improving seventh-grade students’ conceptual understanding. The study employed a Research and Development (R&D) approach using a development model consisting of five stages: analysis, design, development, implementation, and evaluation. The resulting product, named LokaSains, is a web-based learning application accessible via smartphone, laptop, or computer without installation. It presents learning content on temperature, heat, and thermal expansion integrated with the ethnoscience of Cepak Kapung, a traditional cake from Batanghari Regency. Content expert validation obtained a score of 91.07% (very valid), while media expert validation reached 87.50% (very feasible) after two revisions. Teacher practicality assessment produced 98.33% (very practical), and student responses in small-group and large-group trials reached 94% and 90.35%, respectively (very good). During implementation with 28 seventh-grade students, the mean pretest score increased from 46.07 to 76.79 in the posttest. A paired samples t-test produced t = −13.053 with Sig. (2-tailed) = 0.000 < 0.05, indicating a significant difference in conceptual understanding before and after using the multimedia. The N-Gain score of 0.57 indicated moderate effectiveness in improving learning outcomes. Accordingly, the LokaSains interactive multimedia is considered valid, highly practical, and effective for teaching temperature, heat, and thermal expansion at junior high school level.

This research deconstructs the manipulative architecture in the propaganda trilogy of the Japanese Army in 1942, namely Nippon Tjahaja Asia, Nippon Pelindoeng Asia, and Nippon Leader Asia, which have often been reduced to mere political euphemisms. With a descriptive-qualitative design, this study integrates Malcolm Coulthard and Alison Johnson's parameter-based Forensic Linguistics as the grand theory, as well as the three-dimensional model of Norman Fairclough's Critical Discourse Analysis (AWK) as an operational analysis instrument. The results of the analysis show that lexical manipulation through the messianic triptych "Light, Protector, Leader" and the use of assertive clauses without copula are engineered to produce false consciousness. Forensic Linguistic Parameters confirm the existence of a planned mens rea (malicious intent) from Sendenbu, with an extreme disparity between commissive speech in the form of a promise of protection and military actus reus in the form of romusha slavery and logistical seizure. This condition fulfills the elements of mass deception. Furthermore, the doctrinal repetition of the slogan is a form of linguistic coercion that exploits power asymmetry to castrate the people's critical reasoning. In conclusion, the invasion of Japanese fascism in Indonesia did not only take place through military equations, but also through a cognitive dictatorship based on language fabrication. This study is relevant as a historical mirror for detecting the anatomy of structural lies in the contemporary post-truth era.

This study examines Egypt's security dilemma in the Bab el-Mandeb Strait in response to the escalation of Houthi attacks on global maritime trade routes. Since late 2023, Houthi attacks on commercial ships in the Red Sea have disrupted major sea trade lanes, posing a direct strategic threat to Egypt, which relies heavily on Suez Canal revenues as a primary source of national income. This research employs a qualitative approach with a descriptive-analytical method, using secondary data from academic journals, international policy reports, and credible news sources. The analysis is grounded in Security Dilemma theory and the concept of Maritime Security within the framework of International Relations. Findings show that Egypt faces a complex strategic dilemma: on one hand, it must safeguard its economic interests through stable Suez Canal operations; on the other, direct military intervention against the Houthis risks political backlash from Arab public opinion and entanglement in Yemen's civil war. Egypt's response has therefore been calibrated, prioritizing diplomatic channels and multilateral coalition participation over unilateral military action. This research contributes a novelty by specifically mapping Egypt's strategic constraints in the Red Sea as a middle power caught between great power competition and regional non-state actor threats.

Every nation, including Indonesia, has a problem with population growth. A high birth rate is the consequence of an expanding population, which causes childhood malnutrition. Family planning is an attempt to regulate the quantity and spacing of children. The AKDR is the recommended method of contraception. Indonesia's AKDR coverage is still inadequate. Because the husband is the head of the household, his support is crucial since he has the power to decide whether or not to use contraception. At the Ibu Community Health Center, this research aims to explore the connection between husband support and a lack of interest in using IUD contraception among couples of reproductive age. With 25 individuals in the study group, a cross-sectional research design with total sampling methodologies was employed. A survey was used as the research method, and the data was subjected to Chi-Square analysis with SPSS. The chi-square statistical test produced a P-value (asymp. Sig 2-tailed) of 0.000 < 0.05, indicating that there is a correlation between husband support and a low desire among couples of reproductive age to utilize IUD contraception. Consequently, since H0 was disproved and H1 was proven, it can be inferred that there is a link between husband support and couples of childbearing age having a low interest in using IUD contraception.

This article critically examines the training program document for mentors of First Communion candidates at St. Paul Pringgolayan Parish as an institutional religious text. The study employs Peter L. Berger’s theory of the social construction of reality and Michel Foucault’s discourse analysis of power as its analytical framework. Using a qualitative interpretive method, the research conducts an in-depth textual analysis of the document’s narrative structure, normative language, actor relations, and mechanisms of legitimation. The findings reveal that the text is not merely a plan and report of pastoral activities; it also functions as an institutional apparatus that reproduces religious reality while shaping subjects of faith through pedagogical, ritual, and administrative systems. This article argues that pastoral documents can be understood as pastoral social technologies that operate through language to structure religious experience, regulate the distribution of authority, and instill norms of faith practice. These findings contribute to the sociology of religion by demonstrating how faith formation practices at the local level constitute a concrete locus of interaction between the construction of religious meaning and the operation of discursive power.

Digital transformation has brought fundamental changes to the structure and dynamics of modern industrial economics. Technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and big data not only modify production and distribution processes but also revolutionize marketing strategies and patterns of industrial competition. This study is motivated by the need to understand how digital marketing transformation influences the development of competitive advantage through changes in digital market structure from an industrial economics perspective. In this context, digital marketing functions as a strategic instrument that integrates technology, data, and consumer behavior into market mechanisms. The analysis shows that digitalization creates a network-based market structure characterized by the concentration of economic power in major digital platforms and dominance in data control. This structure affects the intensity of competition, the direction of innovation, and patterns of industry differentiation. Digital marketing transformation enhances efficiency, expands market access, and lowers entry barriers for new players, yet it also creates competitive imbalances due to the dominance of large platforms.Through a digital Structure–Conduct–Performance (SCP) approach, the study finds that market structure acts as an intermediary variable that channels the impact of digitalization on competitive advantage. Digitalization significantly promotes industrial efficiency, innovation, and profitability. Proposed strategic solutions include strengthening digital literacy, developing adaptive regulations, and fostering cross-sector collaboration to create an inclusive, competitive, and sustainable digital industrial ecosystem

A single paragraph, maximum 250 words. Abstract content must contain (1) an overview of the object of research, (2) problems, and research objectives, (3) proposed methods, (4) main findings and results and synthesis of main ideas, and (5) conclusions. In recent years, the Iran–United States conflict has not only unfolded within the geopolitical arena but has also been intensively constructed through international media framing that shapes how global audiences understand this reality. In the context of the digital information overflow, media no longer function merely as conveyors of facts; rather, they act as agents that construct meaning, evoke emotions, and shape the social perceptions of audiences. This study aims to analyze how international media framing constructs representations of the Iran–United States conflict and how audiences interpret such discourse within their social experiences. This research adopts a qualitative approach with a Critical Discourse Analysis (CDA) design. Data were collected through document analysis of 25 news articles from both Western and non-Western media, as well as exploratory interviews with nine participants from academic backgrounds. Data analysis was conducted using a thematic approach based on Norman Fairclough’s three-dimensional model. The findings reveal three main patterns: the construction of threat through media language, moral polarization that produces a dichotomy of “us versus them,” and the negotiation of meaning by audiences, which is reflective and not always linear. These findings indicate that audiences are not entirely passive; rather, they actively interpret and, at times, question media framing. Theoretically, this study extends Critical Discourse Analysis by incorporating the dimension of audience experience into the discursive process. Practically, it underscores the importance of critical media literacy in navigating the complexity of global information and opens avenues for further exploration of the relationship between discourse, power, and social experience.
