Abstract

This study presents the analysis of thermodynamic behavior and energy efficiency of a vapor compression refrigeration system with two types of condensers: air-cooled (ACC) and water-cooled (WCC). The main objective is to assess the system performance by comparing the Coefficient of Performance (COP) and Energy Efficiency Ratio (EER) under both condenser configurations. During a 12-hour test period, data on refrigerant pressure, temperature, and electrical energy consumption were collected and analyzed. The results show that the WCC system outperforms the ACC system, showing a 5.7% increase in heat rejection and a 4.2% increase in cooling capacity. In addition, the WCC system exhibits a lower compressor duty cycle and consumes less electrical energy, resulting in a higher total EER of 5.658 compared to ACC of 1.945. These findings suggest that integrating a water-cooled condenser into a refrigeration system can significantly improve energy efficiency and reduce operating costs, making it a viable option for commercial applications in tropical regions.

Abstract

The Indonesian Government releases the Law 6/2014 on Village. Since then, there are lively discussions about its implementation. In its 7th years of implementation, this paper intends to analyse on how and to what extent the implementation of the Village Law has determined village development in Indonesia. This paper is based on case study approach, which is conducted in seven selected villages in East Java Province. Data is collected by series of interviews with village heads, member of village council, women and youth representatives. This paper presents that there are three main popular sectors of village development in Indonesia namely institutional reform, local economic development and applied technology. On this, the paper argues that applied technology is less problematic than the other two. Institutional reform and local economic development are two sector that many problems (social and political) are identified. This relates to existing social-political structures of traditional Javanese village as well as problem of capacity.

Abstract

The Sustainable Development Goals (SDGs), established by the United Nations in 2015, are a comprehensive global framework that addresses social, economic, and environmental challenges through sustainable development. This study examines the role of universities, specifically focusing on the Department of Mechanical Engineering at Universitas Muhammadiyah Magelang (UNIMMA), in contributing to the SDGs. The study utilized data from Elsevier’s SciVal to analyze the department’s contribution to the SDGs through scientific publications in the Scopus database. A total of 97 out of 156 articles published by nine researchers from the department were found to contribute to various SDGs, with a significant focus on Goals 7 (affordable and clean energy), 17 (partnerships for the goals), 9 (industry, innovation, and infrastructure), and 12 (responsible consumption and production). The study highlights the department’s collaborative efforts and alignment with global sustainability goals. In addition, VOSviewer was used to map the research collaboration network within the department, revealing strong contributions to energy efficiency, sustainable technologies, and climate action. However, the department's research shows limited contribution to social SDGs such as poverty alleviation and gender equality. By mapping the university’s contributions to the SDGs, this study helps faculty members identify opportunities for targeted research collaborations, address gaps in SDG contributions, and enhance partnerships with researchers from other institutions, thus broadening the university’s impact on global sustainable development goals.

Abstract

A plethora of studies has examined EFL learners attitudes towards and perceptions of English pronunciation, yet little has been discussed about the influence of religious backgrounds on ones pronunciation abilities, especially in the Thai context. This study aims to extend the research area by studying Buddhist and Muslim EFL learners attitudes and perspectives about their English pronunciation abilities in Thailand. Using a mixed-method design, it collected survey data from 60 undergraduate students (50% Buddhist, 50% Muslim) at a university in south Thailand. An English pronunciation test was conducted to gather data on the students English pronunciation performances. The quantitative findings revealed that Buddhist and Muslim Thai EFL learners possessed moderate levels of attitudes towards their English pronunciation and perceived indirect influences of their religion on their English pronunciation. Although the learners attitudes and perceptions were connected, they were not significant predictors of their actual English pronunciation. Religion and gender had no direct impact on the learners attitudes; however, their frequent religious practices have led to the awareness that students from some religious backgrounds can have an advantage in pronouncing some English sounds, letters, or words over their friends with a different religion. The results of this research also suggest that there is much more to be learned about the effects and contributions of religious backgrounds on learners English pronunciation among learners.

Abstract

The introduction of agencification in state universities, marked by the provision of varying degrees of autonomy, aims to improve service quality and operational efficiency. This study investigates the efficiency of state universities through the lens of agencification, i.e., the use of semi-autonomous or autonomous agencies to deliver public services. The Analytical Hierarchy Process is employed to identify and prioritize key criteria influencing university performance. Drawing on semi-structured interviews and focus group discussions with university managers, policymakers, and academics, we reveal twelve critical factors that contribute to efficiency. The findings reveal an urgent need for innovation across leadership, human resource management, information technology, strategic planning, and governance. The findings highlight the role of visionary leadership, effective human resource management, and stringent internal controls as the dominant criteria. We explore the challenges faced by state universities, including the complexities of autonomy models and bureaucratic constraints. The results imply that while university autonomy can enhance operational efficiency, it must be balanced with accountability mechanisms to prevent disparities. This research contributes to the efficiency scholarship by explaining actionable insights for policymakers and university managers to improve service quality in contemporary governance frameworks.

Abstract

Previous research has validated teachers' positive attitudes toward incorporating digital technology into general English classes, but little research has been undertaken in vocational universities, where English is classified as English for Specific Purposes. As a response, this study explored vocational university teachers’ perceptions of integrating digital technology in teaching English by considering years of teaching experience. Framed by a mixed-method research design with surveys and interviews, it engaged 120 vocational university teachers in Indonesia. Quantitative data were examined using descriptive statistics, paired-sample t-tests, and one-way ANOVA, while thematic analysis was applied to qualitative data. The analysis showed that 66.5% teachers perceived advantageously toward digital technology integration in the teaching of English to vocational university students. The findings disclosed that most participants perceived digital technology integration positively in terms of helping teachers teach English, increasing teachers’ creativity, assisting students in learning English, and supporting teachers’ professional development. Yet, 25% of the participants stated they were neutral, while 8.5% disagreed with the majority. It might be caused by challenges that still arose during technology integration in EFL classes. Further, there were no significant differences in statistical analysis comparing the teachers’ perception based on teaching experience. Several suggestions for teachers, vocational institutions, and educational policymakers were presented to shed light on vocational teachers’ professional development, which could improve the vocational education system.

Abstract

Education plays a very important and strategic role in shaping human resources that are productive, innovative, and have personalities under cultural values. In addition to providing cognitive, affective, and psychomotor values to every citizen, education is also used as a tool to transform values that are expected to be beneficial in the life of society, nation, and state [5]. Gender bias is favoring one gender in social life or public policy. Gender bias in education is an educational reality that favors one particular gender, which causes gender inequality. Various forms of gender inequality that occur in various fields of community life are also represented in the world of education. Educational processes and institutions are seen as playing a major role in socializing and preserving the values and perspectives that underlie the emergence of various gender inequalities in society. The concept of education often appears in literary works. One form of literature that contains about education is drama. Drama is a record of everyday events that are projected onto the stage. In line with that [1] mention that Learning in drama is process-oriented, a state of change that occurs in time and space, which happens within double frames of reality and fiction. Drama learning is process-oriented, with changes in time and space, which frame real and fantasy events. Drama is no different from other literary works, such as novels or short stories. It contains certain issues that the author wants to convey to the reader or audience. The object will be studied by the researchers is Nano Riantiarno's Sampek Engtay, a feminist drama or a drama that talks about women. This drama is very thick with the nuances of feminist criticism, namely the marginalization of education. This research is a qualitative descriptive study. In this research, qualitative information is described carefully and analytically. The description includes forms of criticism of the unfair treatment received by women in the field of education. The approach used in this research is feminism. This approach is used in order to interpret the deep meaning of the literary works studied in relation to people's lives. This is taken based on the assumption that basically literary works are the embodiment of people's lives. Thus the interpretation of the meaning in this literary work is a manifestation of that society.
