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.

Abstract

Pigeon peas(Cajanus cajan (L.)) are a type of legume with potential for development as a sustainable alternative source of plant-based protein. These beans have a relatively high protein content, approximately 27–28%. This study aims to analyze the effects of variations in lactic acid bacteria cultures and incubation methods on the production of yogurt made from local Pigeon peas beans. The study employed a Completely Randomized Design (CRD) to test variations in Lactic Acid Bacteria (LAB) cultures (comprising Greek yogurt culture and powdered culture) combined with three different incubation methods: incubation at room temperature, in a thermos, and in a modified incubator. Data were analyzed using a two-way Anova. The results showed that variations in LAB cultures had a significant effect on protein content, moisture content, fat content, viscosity, and pH. Meanwhile, the incubation method had a significant effect on protein content, moisture content, ash content, total lactic acid, fat content, viscosity, and pH. The best Pigeon peas bean yogurt was obtained from the powdered culture treatment using the incubation method with a modified incubator, yielding a protein content of 3.47%; ash content of 0.69%; total lactic acid of 0.66%; fat content of 1%; viscosity of 0.47 cP; pH of 3.82; and moisture content of 83.19%. The results of the organoleptic test showed that the criteria for color, aroma, and taste were met, while on average, the panelists strongly liked the texture of the yogurt.

Abstract

This study aims to determine the effect of the use of Learning Management System (LMS) and On The Job Training (OJT) on the professional competence of teachers in Bulukumba Regency, both partially and simultaneously. This study uses a quantitative approach with a survey method. Research data were obtained through distributing questionnaires to 18 respondents who are teachers in Bulukumba Regency. The data analysis technique used is multiple linear regression analysis which includes partial tests (t-test), simultaneous tests (F-test), and coefficient of determination with the help of a statistical data processing program. The results of the study indicate that partially the use of LMS has a significant effect on the professional competence of teachers, while the On The Job Training (OJT) variable also has a significant effect on the professional competence of teachers. Simultaneously, the use of LMS and the implementation of OJT have a significant effect on the professional competence of teachers. The Adjusted R Square value of 0.365 indicates that 36.5% of the variation in the professional competence of teachers can be explained by these two variables, while the rest is influenced by other factors outside the research model. Thus, the use of Learning Management System (LMS) and the implementation of On The Job Training (OJT) have a positive and significant effect on improving the professional competence of teachers in Bulukumba Regency.

Abstract

This study aims to analyze the electrical energy performance of the PLN UP3 Bangkinang Office Building through a partial energy audit and to determine the Energy Use Intensity (EUI) as an indicator of energy efficiency. The methodology includes collecting historical electricity consumption data for 2024–2025, inventorying lighting and air conditioning systems, measuring illumination levels (lux) and indoor temperature, and evaluating compliance with SNI 6196:2011, SNI 6197:2020, and Minister of Energy and Mineral Resources Regulation No. 3 of 2025. The results indicate that the EUI value of the PLN UP3 Bangkinang Office Building was 39.33 kWh/m²/year in 2024 and 40.28 kWh/m²/year in 2025, with an average of 39.81 kWh/m²/year. These values are below the benchmark of EUI < 70 kWh/m²/year, categorizing the building as highly efficient. The lighting system analysis shows that most rooms comply with the maximum lighting power density (W/m²) standard, except for the Cendana Meeting Room, which exceeds the limit. In terms of illumination level, several rooms do not meet the minimum lux standard and require optimization without significantly increasing power consumption. Meanwhile, the air conditioning system operates within a comfortable temperature range and is in good condition, contributing to stable overall energy consumption. Overall, the PLN UP3 Bangkinang Office Building demonstrates highly efficient energy performance, with opportunities for improvement in lighting distribution optimization and sustainable energy management practices to maintain a balance between energy efficiency and occupant comfort.

Abstract

The rapid expansion of digital platforms in Indonesia has reshaped its economy, with e-commerce transactions expected to reach IDR 487.01 trillion in 2024, positioning Indonesia as a major player in Southeast Asia's digital economy (Google, Temasek, & Bain, 2023). Despite the advancements, the platform economy has introduced significant inequalities between platform operators and consumers, leading to consumer exploitation through data manipulation, dynamic pricing algorithms, and unclear contract terms. These issues are further exacerbated by Indonesia’s existing legal framework, which struggles to address the challenges posed by digital transactions. This study critically evaluates Indonesia's consumer protection laws and identifies the gaps allowing these exploitative practices. It proposes a legal reconstruction model that focuses on ensuring transparency, fairness, and accountability in digital contracts. The study's key findings highlight the legal deficiencies in regulating platform monopolies, the need for clearer regulations on algorithmic pricing, and the underregulation of data privacy concerns. Recommendations for legal reform aim to enhance consumer protection, creating a more equitable digital economy.

Abstract

Consumer protection in trade transactions has become a critical issue in modern commerce, especially with the rise of digital transactions. Despite existing regulations, many consumers remain vulnerable to information asymmetry, exploitation, and injustice in trade. This article aims to critically evaluate the concept of justice in trade through the perspectives of human rights and public policy. The focus is on consumer protection in sale transactions, both in conventional trade and e-commerce, exploring how human rights principles and public policy can offer solutions to the injustices consumers face. This study employs a juridical-normative approach with a comparative analysis between Indonesian law and international human rights norms. Key legal frameworks such as the Indonesian Consumer Protection Law (No. 8/1999) and the Trade Law (No. 7/2014) are analyzed alongside the UN’s International Covenant on Economic, Social, and Cultural Rights (ICESCR). Primary data was collected through semi-structured interviews with 20 experts, e-commerce businesses, and consumers involved in digital trade transactions. Secondary data was derived from legal documents, consumer protection reports, and literature on Indonesian commercial law. The findings reveal that while Indonesia’s legal framework provides a foundation for consumer protection, its implementation remains inadequate, leaving consumers exposed to unfair practices in online transactions. The article suggests that consumer protection should not merely be a contractual formality but also a moral and ethical responsibility, ensuring consumers' rights to safety, fairness, and transparent transactions. From a human rights perspective, economic justice and social fairness are integral to consumer rights. The state has an obligation to ensure access to clear information, provide mechanisms for redress, and prevent exploitative practices in trade. Public policy must strengthen oversight, regulation, and consumer education in digital trade platforms, ensuring that they are transparent, fair, and provide accessible dispute resolution mechanisms. In conclusion, consumer protection in trade should be viewed not only through contractual agreements but also as part of economic justice, safeguarding consumers' rights to clear information, fair treatment, and the ability to seek compensation for harm. The state must play an active role in fostering a trade environment that aligns with human rights and effective public policy, creating a just and equitable marketplace.
