Abstract

The fulfillment of drinking water needs in Pangkalan Kuras District comes from ground water, bottled water, and river water, of which quality and quantity are not guaranteed according to PERMENKES No. 492/2010. condition of the quality of the quantity of drinking water for the people of Pangkalan Kuras District. The largest source of drinking water used by the community is well water with a percentage of 54.4%, bottled water 45.15%, and the least used is river water by 0.41%. The groundwater in Pangkalan Kuras District is still affected by peat soils, so that the groundwater feels brackish, colored and smells of mud, therefore it needs much deeper drilling to get clean water. While the bottled water used is good for consumption, the quantity and continuity have not been fulfilled because the population density is not evenly distributed in Pangkalan Kuras District. Meanwhile, river water is not of good quality if it is directly used as a source of drinking water.Keyword: Pangkalan Kuras, Drinking Water, Ground Water, Bottled Water, River Water

Abstract

Asphalt mixture for highway pavement consists of aggregate, filler, and asphalt. Materials commonly used as fillers are cement, sand, lime, and rock ash. These materials have limited availability, are relatively expensive, and are nonrenewable materials. One of the alternatives to the filler is oil palm bunch ash which is a waste of the palm oil processing industry and is a renewable natural resource. The purpose of this study was to determine the effect of peat water on the characteristic value of the Marshall AC-WC mixture with oil palm bunch ash as filler. This study used the asphalt content used in the determination of KAO of 5.5%, 6%, 6.5%, 7%, and 7.5%. While the variations filler used were 0%, 2%, 4%, 6%, and 8%. This research was conducted under the General Specifications of Bina Marga 2018. The results of this study show that the AC-WC layer mixture when immersed in peat water has an increased KAO value in the range of 6.08% 7.30%, for variations of filler 6% and 8%. not obtained because the characteristic parameters Marshall do not meet the specifications and the value of stability and durability has decreased. The filler 4%with immersion time of 0.5 hours gave the highest stability value of 919.93 kg, while the lowest yield was obtained at filler 0% with 24 hours soaking time of 513.80 kg. For Variations of filler 0%, 2%, and 4% with soaking time of up to 3 hours, the IKS value is more than 90% so that it meets the specifications. Keywords: Palm Bunch Ash, Filler, Peat Water, AC-WC
