<![CDATA[Vocational students are confronted by intricate demands once they graduate. Despite the considerable need for vocational graduates in the workforce, most students have a limited understanding of digital and vocational information. This study used a descriptive quantitative method to determine the influence of digital and vocational information literacy on students' learning outcomes in three vocational schools in the Sragen Regency. Cluster Random Sampling was used to select a sample of 111 students. Data on digital and vocational information literacy were collected using a questionnaire, while those on the learning outcomes were obtained from the student's grades. The results showed that digital literacy influences vocational students' learning outcomes with a significance of 0.000 < 0.05. Vocational information literacy influences the students' learning outcomes with a significance of 0.000 < 0.05. Furthermore, digital and vocational information literacy simultaneously influence the students' learning outcomes with a significance of 0.000 < 0.05. These results indicate the necessity to familiarize and increase the students' literacy skills to improve learning outcomes. The results indicated that digital and vocational literacy partially and collectively influenced learning outcomes by 48.2%. Therefore, classroom instruction needs to be structured around learning models that actively stimulate the development of digital and vocational literacy skills, preparing students for workplace competitions. Consequently, teachers should consistently implement learning strategies that create a meaningful connection between the school environment and the realities of the professional world.]]>

<![CDATA[Like many countries, an increase in population and economic growth has made Indonesia’s energy demands significantly raise. By 2050, Indonesia hopes to have 31% of its energy supply met by tapping on renewable energy, like the wind which can yield up to 16.7% of the power. However, the development of wind energy in Indonesia is still low. One underlying reason is the average speed of wind in Indonesia quite low, making it very difficult to produce energy on a large scale. Many of Indonesia’s current wind energy systems installed in remote locations, often as part of a development or research project in stand-alone or hybrid systems. These partly caused by a lack of confidence in wind power and not being sure of where could be the best locations for wind plants. This paper studies the status of wind energy in Indonesia, the challenges that it faces and future policies.]]>

<![CDATA[Indonesia possesses significant geothermal energy potential, accounting for approximately 40% of the world's total reserves. However, its utilization in power generation is still constrained by system efficiency limitations. This study aims to assess the thermal performance of the Dieng Unit 1 Geothermal Power Plant (GPP), which currently operates with a 55 MW single-flash system, and evaluate performance improvements through the integration of a double-flash configuration. A numerical simulation was conducted using the Engineering Equation Solver (EES) software, based on actual operational data from January to February 2025. The results indicate that the implementation of the double-flash system enhances energy efficiency from 71.87% to 84.1%, and exergy efficiency from 43.17% to 49.11%. Net power output increased by 7,560 kW by re-utilizing brine from the high-pressure separator. The study further investigates the effects of pressure variation in the Low Pressure Separator (LPS) and turbine efficiency on power output, identifying 1.6 bar as the optimal pressure for maximizing exergy input. These findings confirm that the double-flash system effectively reduces energy losses and significantly improves the plant’s thermodynamic performance. This research provides valuable insights for optimizing geothermal power systems, offering strategic solutions for sustainable energy development in high-potential regions like Indonesia.]]>

<![CDATA[The study in Aerodynamics has shifted from large theoretical curriculum into authentic learning experiences in response to the industry requirement. In addition, the development of computational methods has revolutionized the design cycle in aerodynamics. This work describes an integrated approach in an undergraduate Aerodynamics course using the Kolb’s Learning cycle. Experiential learning is incorporated in the class to provide more opportunities for students to understand the theoretical concept through experiencing the applications and impact of the concept in real life. The Finite Element Method (FEM) which is widely used in analyzing many engineering problems was integrated into the Aerodynamics theory and application to visualize changes of parameter in the design phase. The main learning objective of the developed learning module is to apply appropriate aerodynamics models to predict the forces on and performance of a vehicle design. The module is assessed by instructor before being applied for the students in the classroom. It is considered to be an effective method for learning when lectures and computation works are integrated in a meaningful manner. This development research is expected to be able to produce graduates who are competent in the field of design.]]>

<![CDATA[This paper presents a comprehensive literature review of recent advances in DC–DC converter technologies for hydrogen fuel cell power conditioning, with particular emphasis on proton exchange membrane fuel cells (PEMFCs) used in electric vehicle and stationary energy systems. Covering 29 peer-reviewed studies, the review examines progress in converter topologies, control methodologies, and performance optimization. The analysis highlights interleaved boost converters combined with advanced control strategies—such as linear quadratic regulator (LQR) control, fractional-order PID control, and sliding mode control—as the current state-of-the-art, achieving efficiencies above 95% while substantially reducing input current ripple and improving transient response. Emerging research trends include high-gain impedance-network converters enabling wide input voltage ranges, isolated and bidirectional converter architectures that support hybrid energy storage integration, and intelligent optimization-based control approaches incorporating particle swarm optimization (PSO) and model predictive control (MPC). The review further identifies key trade-offs in efficiency, power density, voltage gain capability, and dynamic behavior across converter designs, providing a structured foundation for future development of high-performance fuel cell power conditioning systems.]]>
