Abstract
Pelepasan emisi menjadi salah satu isu global dalam perkembangan industri beberapa tahun terakhir. Dengan demikian, efektifitas penggunaan sumber material yang berkelanjutan, dapat mempengaruhi parameter dan kuantitas pencemaran udara dari produksi bantalan beton tipe prestressed. Sehingga, analisis dari pemanfaatan sumber material bantalan beton, hingga nilai akhir daur hidup bantalan beton menjadi salah satu faktor kontribusi pelepasan nilai satuan emisi CO2/kg, SO2, dan NO2.Penelitian ini bertujuan untuk menganalisis stabilitas ekosistem dengan mempertimbangkan pencampuran fly ash sebagai bahan material alternatif. Pencampuran komposisi fly ash disimulasikan pada 3 skenario jenis percobaan diantaranya; 100% semen, 90% semen & 10% fly ash , dan 75% semen & 25% fly ash . Komposisi campuran agregat pada semen dan fly ash mampu dijadikan indikator kelayakan produksi bantalan jalan rel kereta api jika pencemaran udara mampu direduksi dengan baik. Pengaruh campuran beton dan fly ash dapat dianalisis dengan menggunakan perangkat lunak uji kelayakan emisi yaitu Simapro 9.0. Hasil analisis melalui tiga skenario yang diasumsikan, impact assessment human toxicity air, masing-masing skenario memiliki skor yaitu, skenario-1 sebesar 0,223 Pt , skenario-2 sebesar 0,221 Pt dan skenario-3 sebesar 0,222 Pt. Sehingga untuk analisis skenario yang tertinggi dihasilkan pada skenario-1. Penerapan penghijauan dan revegetasi di daerah pantai, sebagai investasi biomassa yang dapat menurunkan dampak lingkungan berupa pencemaran udara terhadap global warming.

The release of emissions has become one of the global issues in industrial development in recent years. Thus, the effectiveness of the use of sustainable material sources, can affect the parameters and quantity of air pollution from the production of prestressed type concrete bearings. Thus, the analysis of the utilization of concrete bearing material sources, to the end value of the life cycle of concrete bearings is one of the contributing factors to the release of CO2 / kg, SO2, and NO2 emission units.This study aims to analyze the stability of the ecosystem by considering mixing fly ash as an alternative material. The mixing of fly ash composition was simulated in 3 types of experiments scenarios including; 100% cement, 90% cement & 10% fly ash, and 75% cement & 25% fly ash. The composition of the aggregate mixture in cement and fly ash can be used as an indicator of the feasibility of production of railroad track bearings if air pollution is able to be reduced properly.The effect of the mixture of concrete and fly ash can be analyzed using the emission feasibility test software, namely Simapro 9.0. The results of the analysis through three scenarios are assumed, human toxicity impact assessment of water, each scenario has a score that is, scenario-1 of 0.223 Pt, scenario-2 of 0.221 Pt and scenario-3 of 0.222 Pt. So for the highest scenario analysis produced in scenario-1. Application of reforestation and revegetation in coastal areas, as an investment in biomass that can reduce environmental impacts in the form of air pollution on global warming.
