Abstract

Reduced graphene oxide (rGO) phase from coconut shell charcoal through heating using either a furnace or an artificial burner has been successfully formed. Heating was carried out through 2 temperature variations, namely 500 and 1000ᵒC, with a holding time of 5 hours. Heating through an artificial burner is carried out using used fuel oil equipped with a thermostat to measure the temperature. Phase identification was carried out using Xrays Diffraction Spectroscopy (XRD) testing with an angle of 2θ, namely 15-50ᵒ. The diffraction pattern shows that all samples have rGO phases with different intensity values. The higher the temperature, the greater the intensity value compared to the other samples. This intensity value indicates an increase in the sample's crystallinity due to an increase in temperature.

Abstract

This research conducted focused on the Grati Hospital Building, which is an effort to mitigate global warming by evaluating the building in terms of green building principles. This is because the building is newly constructed and located in an industrial area with a dense population, making it suitable for a case study. The aim is to evaluate the RSUD Grati Hospital building based on the Green Building concept by applying Greenship assessment simulations. This research is classified as quantitative research, focusing on direct observational methods with reference to the Greenship Rating Tools, specifically version 1.2 for newly constructed buildings. The simulation results of the evaluation conducted on the RSUD Grati Hospital building are as follows: (1) Land Use Efficiency scores 7 points, (2) Energy Efficiency and Conservation scores 8 points, (3) Water Conservation scores 10 points, (4) Material Resources and Cycle scores 8 points, (5) Indoor Health and Comfort scores 6 points, (6) Building Environmental Management scores 4 points. Based on the points obtained, the overall rating is Bronze, with a score of 43 points or 42.57%, ranking fourth out of four ranks available, thus qualifying the building as a green building. The distinctive feature of the RSUD Grati Hospital building in implementing green building principles lies in its electricity and water conservation efforts, as reflected in the Energy Efficiency and Water Conservation categories.
