Abstract

Solar energy technology is one of the most rapidly advancing renewable energy solutions aimed at meeting electricity demands in a sustainable manner. This technology converts sunlight into electrical energy through two primary approaches: the photovoltaic (PV) system, which utilizes solar panels to directly transform sunlight into electricity, and the Concentrated Solar Power (CSP) system, which uses mirrors or lenses to concentrate solar heat for electricity generation. The main advantage of solar energy lies in its environmentally friendly nature, as it does not produce carbon emissions or harmful greenhouse gases. Moreover, solar energy is derived from the sun—a renewable and abundant source that will not deplete. Economically, solar technology offers long-term cost efficiency; after the initial installation, operational costs are relatively low and can significantly reduce or eliminate electricity bills. The versatility of solar applications is another key benefit, as it can be used for various needs, ranging from household systems to large-scale industrial projects. With these advantages, solar energy stands as a strategic alternative in supporting the transition toward a cleaner, more sustainable energy system and environmentally friendly, especially within the environment of Mpu Tantular University in Jakarta.

Abstract

Design change is a common risk in construction projects and can significantly impact the efficiency of time control and work quality. This study aims to evaluate the impact of design change risk on time and quality control in a flat construction project in Samarinda. The research method used is a case study with a quantitative and qualitative descriptive approach, through interviews with the project team and analysis of project documents such as shop drawings, implementation schedules, and work progress reports. The results show that design changes that occurred in structural and architectural work caused a delay of 32 days from the initial schedule (from 365 days to 397 days). In addition, a decrease in quality efficiency was found due to revisions to working drawings and adjustments to technical specifications in the field. This impact can be minimized through the implementation of more intensive design coordination between planning consultants, supervisors, and contractors before work begins. This study emphasizes the importance of implementing design change risk management to maintain time control and quality in construction projects.
