Abstract

As the population increases, the amount of plastic waste, especially styrofoam, is also increasing. Styrofoam waste that is not disposed of and accumulates will have a negative impact on health and the environment. On the other hand, the utilization of styrofoam waste as an additional material for building materials is still very minimal. Therefore, this research aims to overcome environmental problems by utilizing styrofoam waste in making paving blocks as an alternative building material. This research uses a quantitative method to determine the quality of paving blocks produced from a mixture of styrofoam and silica fumes. The research process begins with paving blocks containing 10% styrofoam from the total sand, with variations in particle size that pass the mesh sieve of 1mm, 4mm, and 10mm. Styrofoam acts as a partial replacement for coarse and fine aggregates. In addition, silica fume was added as much as 10% of the total cement to partially replace the adhesive material. The results showed that the addition of styrofoam waste with a diameter of 1mm, 4mm, and 10mm mesh passes in paving blocks produced compressive strength values of 18.00 MPa, 29.17 MPa, and 32.34 MPa, respectively, as well as water absorption values of 6%, 4.9%, and 3.6%. The larger styrofoam shredding diameter (10mm mesh) produced the highest compressive strength value (32.34 MPa) and the lowest water absorption (3.6%), meeting SNI 03-0692-1996 and quality classification B for parking lots. The best composition is the addition of styrofoam by 10% of sand and silica fume by 10% of cement, with 10mm mesh shredding diameter. The styrofoam shredding diameter proved to have a significant effect on increasing the compressive strength and decreasing the water absorption of paving blocks. This research is expected to provide a practical solution in reducing styrofoam waste by using it as a building material, while producing paving block products that meet quality standards.

Abstract

Carbon dioxide (CO₂) emissions from the energy sector are a major contributor to global warming, thus becoming a serious challenge in achieving sustainable development. Most industrial areas in Indonesia still rely on electricity supply from natural gas-fired Steam Power Plants (PLTU) which contribute to carbon emissions. Based on these problems, this study aims to: (1) evaluate the existing conditions of the integration of Solar Power Plants (PLTS) with Private Power Generation systems, (2) calculate the potential CO₂ emission reduction from the use of PLTS, and (3) analyze the Economic Value of Carbon (NEK) based on national policies. The method used refers to the 2006 Intergovernmental Panel on Climate Change (IPCC) guidelines with a Tier 2 approach, as well as NEK calculations based on the Regulation of the Minister of Energy and Mineral Resources (Permen ESDM) No. 16 of 2022. The results of the study show that the current PLTS integration uses an On-Grid system with a capacity of 30% of the connected capacity. This condition causes the emission reduction achieved to be still limited due to regulatory restrictions. To achieve optimal emission reductions, a transition to an off-grid system is necessary. The economic value of carbon from solar power plant utilization shows a surplus of IDR 812,463,000 per year. Further research is recommended to examine hybrid system scenarios, long-term economic analysis, and the impact of carbon incentive policies on accelerating renewable energy adoption in the industrial sector.
