PENGARUH PENAMBAHAN LIMBAH SERABUT KELAPA PADA CAMPURAN (ASPHLAT TREATED BASE) ATB DITINJAU DARI NILAI PARAMETER MARSHALL TEST

Abstract

Increased activity of the oil palm plantation industry in Muara Wahau village, East Kutai Regency, East Kalimantan Province, which has resulted in piles of waste, one of which is palm oil fiber waste. This research carried out the utilization of oil palm fiber waste that has not been optimized with the aim of knowing the effect of adding palm fiber waste to the ATB foundation layer on the characteristic value of the Marshall Test and knowing the feasibility of palm oil fiber waste as an additive to the ATB mixture. The research was conducted by looking for the value of KAO with asphalt content variants of 4%, 4.5%, 5%, 5.5%, and 6% with each of the variations in asphalt content made by 5 specimens, and obtained KAO of 5.43%.The planning for hot mix again used KAO asphalt levels and the addition of palm oil waste with variations in levels of 1.5%, 3%, 4.5% and 6% for each grade made of 3 objects. From the results of the research, the added material for palm oil fiber waste mixed with ATB affects the characteristic value of Marshall significantly. From the results of testing the hypothesis Stability Fcount = 12.71, Flow Fcount = 5.47, VIM Fcount = 3344.49, VMA Fhitung = 3347.46, MQ Fcount = 65.89, VFA Fcount = 3582.70> Ftable = 3.478. And based on the research results, it is stated that palm oil fiber waste is not suitable for use as an added material, because the results of VIM and VFA have decreased which do not meet the requirements of the 2018 Highways Specifications.
