Penelitian ini akan melihat pengaruh penerapan <em>carbon tax </em>khususnya pada industri konstruksi di negara-negara yang telah menerapkan sebelumnya dan melihat potensi penerapannya di Indonesia. Analisis SWOT digunakan  untuk mengetahui faktor-faktor internal maupun eksternal dalam penerapan kebijakan <em>carbon tax</em>. Hasil menunjukkan bahwa kebijakan <em>carbon tax</em> dapat mendukung program pemerintah sebelumnya yaitu Skema Karbon Nusantara yang dapat mendukung pendanaan penerapan program pemerintah seperti <em>green building</em> dan infrastruktur berkelanjutan khususnya pada proyek-proyek pemerintah.

This research aims to identify the effect of carbon tax implementation in the construction industry in several countries and analyze the potential for its application in Indonesia. The SWOT analysis was carried out to determine internal and external factors in the implementation of a carbon tax policy. The result shows that the policy can support the previous program by the Indonesian government, namely the Nusantara Carbon Scheme to promote the funding for other related programs such as green building and sustainable infrastructure. However, it should be noted that the policy may also have a negative impact on economics. Therefore, it is necessary to use tax revenue sources in achieving Indonesia's GHG emission reduction targets.</p><p class=\"11daftarpustaka\"> </p><p class=\"11daftarpustaka\">Keywords: <em>carbon tax, carbon emissions, carbon policy, CO₂ emissions, carbon construction</em></p><div id=\"","PeriodicalId":52898,"journal":{"name":"Teras Jurnal Jurnal Teknik Sipil","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41988306","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the domestic wastewaters in the city of Jakarta is treated with a centralized system and treated with a waste stabilization pond (WSP). Increasing the number of services and changing wastewater characteristics can affect WSP performance. The purpose of this study is to evaluate the performance of wastewater treatment with WSP in the city of Jakarta. The measurements were carried out at the inlet and outlet of the WSP system and based on the parameters of Biological Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), pH and Ammonia. Based on the standards set by the Indonesian government, all of these parameters have met the quality standards. Efficiency of removal of parameters BOD, COD, TSS, ammonia is 96.22% respectively; 88.66%, 96.19%, 98.62%. The pH of the processing is also in a neutral pH condition, namely 6.5-8.5.

On roads in the Aceh, you can find cow dung scattered on the road. Cow dung contains a lot of nutrients and a fairly high water content and can be suspected as a factor causing road pavement damage. One way to overcome the damage to the pavement is to modify the asphalt using added materials, namely polymers. The polymer used is Low-Density Polyethylene (LDPE) plastic waste as a substitute for asphalt.
