ANALISIS PENAMBAHAN ABU CANGKANG SAWIT PADA CAMPURAN LAPIS ASPAL BETON (LASTON)

Abstract

ABSTRAKLimbah adalah kotoran atau buangan yang merupakan komponen pencemaran yang terdiri dari zat atau bahan yang tidak mempunyai kegunaan lagi bagi masyarakat. Penambahan abu cangkang kelapa sawit pada campuran lapis aspal beton di penelitian ini merupakan salah satu upaya pemanfaatan limbah dari produksi minyak kelapa sawit (MKS) agar limbah yang dihasilkan seminimal mungkin hasil produksinta tanpa limbah. Tujuan adalah untuk mengetahui nilai kekuatan (stability) dan keawetan (durability) pada campuran lapis aspal beton (Laston). Hasil uji stabilitas (kekuatan) penambahan abu cangkang sawit rata-rata 5 % = 957,52 Kg, 10 % = 1.599,37 Kg, 20 % = 1.498,98 Kg, 30 % = 803,28 Kg dan 40 % = 888,40 Kg.. Nilai uji durabilitas (keawetan) penambahan abu cangkang sawit rata-rata 5 % = 71,84 %, 10 % = 74,44 %, 20 % = 107,12 %, 30 % = 77,18 % dan 40 % = 84,81 KgKata kunci: Abu Cangkang Sawit, Stabilitas, Durabilitas, Laston ABSTRACTWaste is dirt or waste which is a component of pollution consisting of substances or materials that no longer have any use for society. The addition of oil palm shell ash to the concrete asphalt layer mixture in this study is an effort to use waste from palm oil production (MKS) so that the resulting waste is as minimal as possible without waste. The aim is to determine the value of the strength (stability) and durability (durability) of the mixture of asphalt concrete (Laston). The results of the stability test (strength) of the addition of palm shell ash with an average of 5% = 957.52 Kg, 10% = 1,599.37 Kg, 20% = 1,498.98 Kg, 30% = 803.28 Kg and 40% = 888, 40 Kg.  The value of durability test (durability) for the addition of palm shell ash on average 5% = 71.84%, 10% = 74.44%, 20% = 107.12%, 30% = 77.18% and 40% = 84.81 KgKeywords: Palm Shell Ash, Stability, Durability, Laston
