Abstract

The implementation of construction work is sometimes not according to the predetermined plan, such as an increase in implementation time which results in the project being late, if there are signs of a delay in a work an alternative can be done immediately to speed up the time so that the project can be carried out as previously planned. The research carried out aims to analyze the optimum time and cost of the Grand Heaven Jakarta Funeral Home Elevator Extension Structure Development project after acceleration. This research implements the method through increasing the number of working hours and employees known as time cost trade off analysis or analysis of the exchange of time and costs. The procedure is through reducing the duration of work that has been planned previously which occupies the critical path section with the aim of obtaining benefits both in terms of cost and project time. This is intended to speed up the project completion time.

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.
