Abstract

The amount of plastic waste, especially disposable plastic bottle waste (PET), needs to be utilized. plastic bottle waste is a flexible material that can be used as an alternative additive to the pavement mixture so as to reduce the production of PET disposable bottle waste. So this research needs to be done to find out its utilization. The purpose of this research is to analyze Polyethylen Terephtalate (PET) plastic bottle waste can be used as an additive and analyze the amount of Polyethylen Terephtalate (PET) bottles needed for Asphalt Concrete Wearing Course (AC-WC) pavement mixtures. The method used is an experimental method carried out in two stages. The first stage of Marshall testing without using plastic to find the Optimum Asphalt Content (KAO) with variations of 4%, 4.5%, 5%, 5.5%, 6%, 6.5%. The second stage of Marshall testing using the optimum asphalt content (KAO) obtained from stage one with additional variations of Polyethylen Terephtalate (PET) plastic bottle waste 1%, 2%, 3%, 4%, 5% to get the optimum PET content. The results of stage one Marshall testing obtained an optimum asphalt content of 5.675%, while Marshall in the second stage obtained an optimum PET content of 0.45% equivalent to 0.0026 gr and all types of Marshall parameters met the Bina Marga 2018 revision 2 specifications for mixing Asphalt Concrete Wearning Course (AC-WC). Each production of one ton of Asphalt Concrete Wearning Course (AC-WC) requires 204.3 bottles of Polyethylen Terephtalate (PET) plastic.The amount of plastic waste, especially disposable plastic bottle waste (PET), needs to be utilized. plastic bottle waste is a flexible material that can be used as an alternative additive to the pavement mixture so as to reduce the production of PET disposable bottle waste.

Abstract

This study aims to analyze the water quality status of the Buol River using the Pollution Index (IP) method. The location of the study area includes the Buol River, with a length of 60.3 km. There are 8 locations for sampling the Buol River water. Determining the location of river water sampling is done by the purposive sampling method. Location criteria are determined based on pollutant sources, namely agricultural waste, domestic waste, and industrial waste. Water quality parameters analyzed were temperature, TDS, TSS, pH, BOD, COD, DO, Nitrate, Nitrite, Ammonia, Chlorine, Sulfide, Phosphate, Surfactant, Fatty Oil, Phenol, and Total Coliform. The river water quality standard used is Republic of Indonesia Government Regulation Number 22 of 2021 Appendix VI. The analysis method for the water quality status of the Buol River is determined by the pollution index method. The results of the quality analysis of the Buol River on the parameters TSS, COD, Nitrite, Chlorine, Sulfide, and Phenol have exceeded the quality standards. The results of the analysis of the water quality status using the Pollution Index (IP) method obtained the Buol River water pollution index at sample point 2 was 3,94 (lightly polluted water quality status). The pollution index value at sample point 1 is 5.16 (moderately polluted). The pollution index value at sample point 3 is 5.24 (moderately polluted). The pollution index value at sample point 4 is 8.03 (moderately polluted). The pollution index value at sample point 5 is 7.36 (moderately polluted). The pollution index value at sample point 6 is 7.73 (moderately polluted). The pollution index value at sample point 7 is 7.40 (moderately polluted). The pollution index value at sample point 8 is 7.79 (moderately polluted).
