Abstract


Abstrak

Pertumbuhan sektor konstruksi akan mampu menarik pertumbuhan sektor pendukung serta mendorong pertumbuhan sektor pembangunan yang lain, namun sektor konstruksi turut berkontribusi dalam konsumsi energi serta menghasilkan emisi gas rumah kaca (GRK), salah satu kegiatan konstruksi yang diperkirakan mengkonsumsi energi dan menghasilkan emisi gas rumah kaca cukup besar adalah konstruksi jalan, dalam hal ini dilaksanakan suatu analisis konsumsi energi dan emisi gas rumah kaca pada pekerjaan konstruksi jalan Cisumdawu dengan perkerasan kaku pada STA 10+700 hingga STA 11+500 meliputi pekerjaan subgrade (galian dan timbunan), pekerjaan lapisan subbase, serta pekerjaan perkerasan kaku dengan menggunakan pendekatan life cycle assessment. Dari hasil analisis diperoleh pekerjaan perkerasan kaku berkontribusi 78.78%, sedangkan pekerjaan subbase berkontribusi 17.04% dan pekerjaan subgrade berkontribusi 4.18%. Sementara itu secara keseluruhan material berkontribusi sebesar 92.80%, kegiatan transportasi berkontribusi 1.97% dan kegiatan Konstruksi berkontribusi 5.23% dari total besaran dampak lingkungan yang dihasilkan dari konstruksi jalan tersebut.

Abstract

The growth of the construction sector will be able to attract growth in the supporting sectors and encourage the growth of other development sectors, but the construction sector also contributes to energy consumption and produces greenhouse gas (GHG) emissions, one of the construction activities that are estimated to consume energy and produce greenhouse gas emissions is a road construction, in which case an analysis of energy consumption and greenhouse gas emissions at Cisumdawu road construction with rigid pavements at STA 10 + 700 to STA 11 + 500 includes subgrade (excavation and piling) using life cycle assessment approach. From the analysis results obtained rigid pavement contributed 78.78%, while subbase work contributed 17.04% and subgrade contributed 4.18%. Meanwhile, overall materials contributed 92.80%, while transportation activities contributed 1.97% and Construction activities contributed 5.23% of the total environmental impacts resulting from the road construction.
