State speeches in international forums are a strategic arena for the practice of diplomacy and leadership image management. This study analyzes President Prabowo Subianto's rhetorical style in his speech at the 80th UN General Assembly on September 23, 2025. Using Aristotelian theory, namely ethos, pathos, and logos, to understand how rhetoric functions in strengthening political legitimacy, humanitarian solidarity, and international policy arguments. Using a qualitative-descriptive approach, this study examines transcripts of official speeches and identifies quotations that represent each persuasive mode. The analysis shows that Prabowo builds ethos through historical references, concrete actions of Indonesia such as the contribution of peacekeeping troops, and pathos is depicted through narratives of suffering, calls for solidarity, and an emphasis on the future of the younger generation; while logos is demonstrated through the presentation of data, policy plans such as the net-zero target, technical solutions such as sea walls, and systematic cause-and-effect arguments. This combination of ethos, pathos, and logos confirms that the speech was not simply a policy statement but also a rhetorical diplomatic tool that strengthened Indonesia's image as a constructive global actor. These findings contribute to the study of leadership communication and diplomatic rhetoric, particularly in the context of developing countries seeking to enhance the role of multilateralism and soft power.

This study aims to conduct an in-depth analysis comparing the legal mechanisms of constitutional amendment in Indonesia and South Africa. The research employs a normative juridical method with a comparative law approach. Primary data is sourced from the authoritative texts of the 1945 Constitution of the Republic of Indonesia (UUD 1945) and the Constitution of the Republic of South Africa, 1996. Data analysis is conducted qualitatively using content analysis techniques on provisions related to constitutional amendments in both supreme legal documents. The research findings reveal fundamental differences in the constitutional amendment paradigms of both countries. First, Indonesia adopts a rigid amendment system implemented by the People's Consultative Assembly (MPR) with very strict quorum and approval requirements. Second, South Africa adopts a more flexible and differentiated system, where Parliament acts as the constituent authority, with varying approval levels depending on the substance of the amended provisions ranging from simple majority to two-thirds, and even involving the Provincial Council for certain matters. Third, despite different approaches, both countries affirm the principle of constitutional supremacy. These mechanistic differences reflect Indonesia's strategic choice to prioritize consensus and constitutional stability, while South Africa emphasizes constitutional adaptability and responsiveness to socio-political developments.

Waste candlenut shells are one type of biomass that has significant potential to be developed as an alternative energy source, particularly in the form of briquettes. Candlenut shells, which are typically discarded as agricultural waste, contain combustible material that can be transformed into solid fuel. However, the traditional briquette molding process is still done manually, which is time-consuming, inefficient, and often results in inconsistent briquette shapes and density. This study aims to design and develop a briquette molding machine specifically for processing candlenut shell waste, with the goal of improving both production efficiency and the quality of the briquettes produced. The research methodology includes several stages: mechanical design, selection of appropriate materials, fabrication of machine components, assembly, and performance testing of the machine. The resulting machine utilizes a screw conveyor compression system powered by a 5.5 HP petrol engine. It features a cylindrical mold with a 40 mm diameter to shape the briquettes uniformly. During the performance test, the machine demonstrated a maximum production capacity of 14.3 kg per hour, with an average processing time of 24 minutes and a briquette yield reaching up to 85%. The findings indicate that the machine can significantly streamline the briquette production process while maintaining product consistency and quality. This briquette molding machine is particularly suitable for household and small-scale industries aiming to utilize renewable energy sources and reduce dependency on fossil fuels. The use of this machine also supports environmental sustainability by converting agricultural waste into a usable energy product.

This design is expected to improve energy efficiency while reducing the operational costs of water heaters on ships. The research methodology includes system design, hardware assembly, and performance testing, both static and dynamic. Testing was conducted to evaluate temperature stability and energy efficiency in system conditions with and without the use of paraffin wax. The results showed that paraffin wax improved water temperature stability while reducing the frequency of heater activation. In a 24-hour test, the system without paraffin wax recorded a heater operating time of 15 hours, consuming 8.85 kWh of electricity and costing Rp11,965.20. In contrast, the Paraffin Wax system only requires 10 hours of heater operation, consumes 5.90 kWh, and costs Rp7,976.80. This demonstrates energy savings of 2.95 kWh and a cost efficiency of up to 58%. Therefore, the ESP32-based water heater automation system and heat storage using Paraffin Wax are proven to be more energy-efficient, cost-effective, and have the potential to be an innovative and environmentally friendly solution for ship operational needs.

This study presents a modal analysis of Pertamina EP Cepu’s closed drain pump 510-P9002, which operates in the condensate–water treatment unit of the Jambaran Tiung Biru field. Field vibration measurements conducted in August 2024 indicated a fundamental frequency of 25 Hz, corresponding to 1×RPM of the driving motor, with maximum amplitudes reaching 13.46 mm/s. Such excessive vibration poses risks of mechanical damage, reduced equipment service life, and potential operational failure. To address this issue, finite element analysis (FEA) was employed to examine the dynamic response of the pump, determine its natural frequencies, and identify possible resonance conditions. A CAD model of the pump–vessel assembly was developed, meshed, and analyzed under actual boundary conditions. The results showed several natural frequencies ranging between 23.16 and 26.65 Hz, which are close to the excitation frequency, suggesting a very high likelihood of resonance. Various structural modifications were then evaluated, including a half casing and two types of full casings. Among these, the full casing B design provided additional stiffness in the motor support area; however, none of the modifications effectively reduced vibration within the internal components. Based on these findings, the study recommends the implementation of a dynamic vibration absorber (DVA) tuned to the excitation frequency, along with the redesign of structural components to shift natural frequencies away from operating excitation. These solutions are expected to improve operational stability, extend equipment lifespan, and enhance overall system reliability. The outcomes of this research provide important insights for managing vibration issues in pump systems operating under similar conditions, particularly in the oil and gas industry where continuous, stable operation is critical.

This approach was chosen so that participants not only gain theoretical knowledge but also practical skills that can be immediately applied. Evaluation was carried out through observing reading ability, courage to ask questions, and active participation in group exercises. The results of the activity showed a significant improvement in the participants' Qur'an reading skills, both in terms of letter pronunciation, application of Tajweed rules, and fluency in reading holy verses. The participants' enthusiasm was evident in their eagerness to participate in all sessions, their sincerity in practicing, and their active interaction during the learning process. Furthermore, this activity also fostered new motivation for participants to continue improving their reading quality independently and create a conducive learning environment in the Islamic study groups. Thus, this training proves that the right learning strategy, supported by high motivation from participants, can have a positive and sustainable impact on improving the quality of Quran reading. It is hoped that this type of program can be replicated in other Islamic study groups so that its benefits are even broader for the community.

Limited sanitation facilities among street vendors, particularly those selling meatballs, chicken noodles, and porridge, often pose a problem that impacts food safety. One common practice is repeatedly washing bowls and spoons with just a bucket of water, followed by drying the utensils with a cloth. This contaminated water can transmit pathogenic microorganisms that cause foodborne illnesses, increasing the risk of health problems for consumers. This problem requires a practical solution that street vendors can implement, taking into account limited space, mobility, and operational costs. This community service activity used a pre-experimental design method with a simple technological engineering approach to improve the sanitation of tableware. The innovation developed was a portable bowl washer made from used mineral water gallons, modified to be mobile, efficient, and water-efficient. The manufacturing process included design, assembly, testing, and evaluation with street vendors. Success was measured by observing the level of cleanliness of the tableware before and after use, as well as assessing the level of satisfaction and ease of use by the vendors. The results showed that the implementation of this portable sanitation device increased the effectiveness of tableware washing, reduced the repeated use of dirty water, and minimized the risk of cross-contamination. Partnering vendors stated that the device is practical, lightweight, and doesn't disrupt their sales activities. They hope this innovation will be replicated by other vendors and that local governments will consider implementing it as a standard for mobile food sanitation. This effort will not only improve the hygiene of eating utensils but also contribute to preventing foodborne illnesses in the community.

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.
