Abstract

This paper presents a hybrid system that consists of a pSOFC (proton conducting SOFC) stack, a micro gas turbine (MGT), a combustor, a compressor, a heat exchanger, and an external steam reformer. This simulation is based on thermodynamic analysis and is developed using Matlab/Simulink/Thermolib software and validated using published data from the literature. Furthermore, three cases, cases 1, 2, and 3, are analyzed, and the best case, case 2, is installed with anode and cathode recycling, to increase system performance. According to the results, case 2 exhibits the highest system efficiency (72%) due to high hydrogen production, and the installation of anode and cathode recycling further increases system efficiency up to 79%.

Abstract

Steam reforming is a method for producing hydrogen gas as a solution for renewable energy generation. One source of hydrogen in a steam reformer is propane gas. The advantage of propane gas is the ease of transportation and storage. The production of hydrogen gas in a steam reformer is certainly influenced by supporting factors such as the temperature of the reformer. In this study, propane steam reforming was simulated in 3D with COMSOL Multiphysics 5.3ª software with bed reformer temperatures varying from 600, 650, 700, 700, 750, 800 and 850 oC with steam to carbon (S/C) ratio 3. The results show that increasing the temperature causes the density of the reformer to decrease, which in turn results in increased gas velocity. In addition, an increase in temperature in the bed reformer increases propane conversion to 87.8% and produces about 40% hydrogen at 850 oC.

Abstract

Remote areas in Indonesia rely on diesel power plants with high costs, environmental impacts, and limited electricity access. Battery-based solar power offers a sustainable solution for 24-hour electricity while supporting digital economic growth. This study analyzes the combined capacity of PLTD and PLTS in providing continuous power in Sigapokna Village, Mentawai Islands. This study used comparative analysis methods, which compares conditions before and after PLTS operation. Results show that integration of 45 kW PLTD and 30 kWp PLTS increases customer operating hours from 7 hours to 10 hours per day, and planned PLTS expansion up to 170.8 kWp has potential to extend operating hours to 14 hours, even up to 24 hours with 319 kWp capacity. However, this capacity increase also impacts increased fuel oil consumption (BBM), demanding better energy efficiency strategies. These findings not only contribute to technical aspects of energy provision but also have significant implications for creative economy development and digital business in remote areas. Sustainable electricity access opens opportunities for Micro, Small, and Medium Enterprises (MSMEs) to utilize digital platforms, e-commerce, and digital financial services, while encouraging the birth of new digital-based energy business models (digital green business model) through Internet of Things (IoT) utilization, smart metering, and energy consumption data analysis. Thus, 24-hour electricity provision based on renewable energy not only improves community quality of life but also becomes a catalyst for digital economic transformation and social inclusion in Indonesia's 3T regions.

Abstract

This study presents empirical evidence on the condition of entrepreneurship education from universities in ASEAN countries facing the ASEAN Economic Community (AEC). Survey data was obtained from 174 lecturers in five ASEAN countries and was analysed using a normality test with PP-plot and a linearity test. The urge of this study is to integrate the managerial and marketing skills in the entrepreneurship education curriculum in higher education in the face of a rapidly changing global business condition. The government must ensure that higher education institution (HEI) in the country creates a business ecosystem in the internal campus environment or encourages students to seek a business ecosystem outside the HEI and creates mentors from lecturers to accompany these students. Theoretically, this study has expanded the theory of entrepreneurship education, competitive intelligence, and readiness to change in the context of ASEAN institutions. In practice, this study helps in preparing an entrepreneurship education agenda for both leaders and educators who influence entrepreneurship education to become more effective, so that their students can apply their entrepreneurship skills after they graduate.
