Abstract

Kajian beban emisi telah dilaksanakan di lingkungan Institut Teknologi Kalimantan (ITK) dalam kurun waktu satu hari. Perhitungan beban emisi CO, NOx, PM10, SO2, HC dihitung menggunakan metode TIER 2, yaitu dengan cara menghitung perjalanan rerata kendaraan, atau Vehicle Kilometer Traveled (VKT) dan kemudian dikalikan dengan faktor emisi masing-masing jenis pencemar untuk tiap jenis kendaraan berbeda. Sedangkan untuk pencemar CO2 menggunakan metode perhitungan jumlah konsumsi bahan bakar dikalikan dengan faktor emisi. Setelah perhitungan didapatkan bahwa jenis kendaraan yang mendominasi adalah sepeda motor. Emisi terbesar terjadi pada pukul 09.30-10.30 yaitu pada jam peralihan perkuliahan sesi 1 dan sesi 2, yang dapat diidentifikasi sebagai jam sibuk. Emisi pencemar terbesar adalah CO2 yaitu sebesar 248.31 Kg/hari diikuti oleh CO sebesar 41.53 Kg/hari. Pencemar udara yang paling sedikit diemisikan adalah SO2 yaitu hanya sebesar 0.028 Kg/hari. Pencemar lainnya yaitu NOx sebesar 0.986 Kg/hari dan PM10 sebesar 0.656 Kg/hari. Dominasi emisi sepeda motor terlihat jelas pada pencemar CO, HC dan CO2, sedangkan pada pencemar lainnya, mobil bensin maupun solar juga berperan dalam mengemisikan pencemar tersebut.

Abstract

PLTU Teluk Balikpapan with a 2 x 110 MW capacity generated fly ash and bottom ash as its waste. The waste was treated by backfilling on open land or called a landfill. The landfill was not effective because it required a large area to accommodate the waste. This research aimed to analyze waste treatment's environmental impact and identify the best scenario from three fly ash and bottom ash treatment options. The first scenario was the existing treatment that used landfill, the second was utilization into paving blocks, and the third was utilization into compost. The method in this research used Life Cycle Assessment (LCA) method. The LCA stages referred to ISO 14040 of 2006 which consists of objectives and scope, inventory analysis, impact analysis, and interpretation. The results of the analysis of the contribution of impacts on the environment with Scenario 1 obtained three impacts with the highest value, namely natural land transformation with a value of 15.8 then climate change with a value of 9.5, and particulate matter formation with a value of 6.8. Furthermore, the calculation shows that the best scenario for fly ash and bottom ash waste treatment was scenario 3: processing into compost.
