Abstract

This study aims to analyze the improvement in energy efficiency of air conditioning (AC) systems after repairs and routine maintenance. The use of unmaintained AC units leads to an increase in energy consumption, which results in higher operational costs. This research measures the changes in electrical power consumption and cooling capacity at two locations: the village office and a residential house. The results show a 25% reduction in power consumption at both locations after the repairs were made, as well as an 8.6% improvement in cooling capacity at the village office and a 13.6% improvement at the residential house. The study also identifies factors that affect energy efficiency, such as refrigerant leaks and component cleanliness. The findings of this study are expected to provide insights into the importance of maintenance and repairs for AC systems to enhance energy efficiency

Abstract

The use of various technologies in vocational high schools in response to the need for graduates to have digital and English skills have changed English instruction even more. This study attempts to analyze the issues and the possibilities that both educators and learners face as they use digital technologies in English teaching. This study is limited to five English teachers in vocational high schools in West Sulawesi, Indonesia. This case study employed qualitative methodology through in-depth interviews and ATLAS.ti 24 software was used for data analysis. Findings showed that the teachers face several issues including the lack of technology, poor and unreliable internet, limited assistance, and different amounts of digital skills students have. Nevertheless, the study also showed that teachers' use of different digital technologies and more varied methods of teaching English motivated students to become involved and participate in English learning more than they have in the past. In addition to this, more skilled teachers are better able to adapt their material to fit vocational contexts and therefore increase relevancy to students’ future workplace outcomes, as this study has shown. The study adds to the knowledge base by showing that the successful application of digital technologies in vocational English education is not only a question of existing digital technologies and infrastructure, but also of ongoing professional digital pedagogical training and educational organizational support. The authors of the study are suggesting that digital infrastructures are available, that there are ongoing training efforts, and that there is a balanced provision of digital tools and resources for educators. These steps are required to take full advantage of digital technologies for teaching and learning English in vocational secondary education.
