Abstract

The escalating household electricity consumption presents significant challenges for energy management and sustainability, with lighting systems accounting for 20-30% of total residential energy usage. The increase in household electricity consumption is a major concern in energy efficiency. One solution that is widely recommended is the use of energy-saving lamps such as Light Emitting Diode (LED). This study aims to comprehensively analyze the impact of LED lamp adoption on household electricity savings by comparing energy consumption, cost efficiency, and environmental benefits across different lighting technologies including incandescent, fluorescent, and LED lamps. This study aims to analyze the effect of LED lamp use on electricity savings in households. The research methodology employs an experimental quantitative approach involving five urban households, each utilizing 10 lighting units under controlled conditions. The study compares 60-watt incandescent lamps with 10-watt LED lamps over a 30-day period, with standardized usage patterns of 6 hours daily operation. Data collection includes power consumption measurements, electricity cost calculations based on prevailing tariffs (IDR 1,500 per kWh), and comparative analysis of long-term cost-benefit ratios including lamp lifespan and replacement frequencies. The results of the study showed that LED lamps were able to save energy up to 80% compared to incandescent lamps and 50% compared to fluorescent lamps. The implications of this research support the transition to LED lighting technology as an effective strategy for household energy management, contributing to reduced electricity bills, lower carbon emissions, and sustainable energy consumption patterns that benefit both individual households and national energy security objectives.

Abstract

The purpose of writing this journal is to analyze the role of the Quality Management System (QMS) in improving the effectiveness of academic information systems in higher education. Currently, academic information systems have become one of the key factors in supporting educational processes, ranging from student data management to academic administration; however, many institutions still encounter issues such as invalid data and slow processes. By implementing QMS, institutions are expected to apply quality standards that meet established requirements. In this study, a descriptive qualitative method was used with a narrative analysis technique, focusing on the application of ISO 9001 as the QMS standard. The results of the analysis indicate that consistent implementation of QMS can significantly improve the efficiency of academic information systems, both in terms of service speed and data accuracy. This analysis concludes that the integration of QMS, particularly ISO 9001-based systems, is an essential strategy for higher education institutions in establishing effective, efficient, and sustainable academic information systems.

Abstract

Synchronous generators are one of the most widely used electrical machines in power systems, especially in power plants. This abstract is based on the background that there are no practical tools specifically used for testing synchronous generators in laboratories, requiring supporting facilities in the form of practical media that can directly support theory and application. The objective of this final project is to design and build a Synchronous Generator Testing Trainer Kit that can be used to perform basic tests such as voltage, current, and frequency using a systematic method that is easy for users to operate. The results of the design show that the trainer kit functions well as a learning medium, as demonstrated by the synchronous generator's stable operation, clearly measurable electrical parameters, and a safe and easy-to-understand testing system, thereby supporting the practical process and understanding of the working concepts of synchronous generators. Based on the results of testing and use of the tool, it can be concluded that the designed synchronous generator testing trainer kit is capable of being a solution to the limitations of practical tools in the laboratory, as well as increasing students' understanding of the working principles and testing of synchronous generators in a practical and applicable manner.
