Abstract

Pembangunan dan peningkatan konstruksi jalan di Aceh Barat dikerjakan oleh Dinas Pekerjaan Umum dan Penataan Ruang Kabupaten Aceh Barat, salah satunya yaitu Jalan Alue Keumuneng yang berlokasi di Kecamatan Woyla. Penelitian ini bertujuan untuk mengidentifikasi dan menentukan lintasan kritis proyek Peningkatan Jalan Alue Keumuneng dan menghindari keterlambatan dan penundaan waktu pekerjaan. Metode Pengolahan dan analisis data dilakukan dengan metode CPM (critical path method) untuk mengetahui lintasan kritis dengan menggunakan software Microsoft Project 2013 untuk memudahkan proyek konstruksi. Hasil penelitian menunjukan kegiatan mobilisasi, penyiapan badan jalan, timbunan pilihan dari sumber galian, lapis pondasi agregat kelas A, lapis pondasi agregat kelas B, lapis resap pengikat-aspal emulsi, laston lapis antara (AC-BC), bahan anti pengelupasan, keselamatan dan kesehatan kerja dan demobilisasi berada pada jalur lintasan kritis, penundaan pada pekerjaan lintasan kritis dapat mempengaruhi penundaan dan keterlambatan keseluruhan proyek. Kata kunci: CPM, network diagram, Alue Keumuneng, Aceh Barat

Abstract

Admixture is an additional ingredient in concrete that is added when mixing concrete takes place in the hope of changing the properties of concrete to make it more suitable for a particular job. In this study, the material used was Sikacrete W with a percentage of 0%, 13% and 16% by weight of cement. The specimens used were cylinders (15 x 30) cm of 12 specimens for each FAS. FAS variations in this study included 0.35, 0.40 and 0.50 with a test age of 28 days. The results of this study, for FAS 0.35 the average concrete compressive strength for STATPLA was 280.24 kg/cm2, STATPDA was 110.38 kg/cm2, SDATPDA (13%) was 244.00 kg/cm2 and SDATPDA (16%) was 256.89 kg/cm2. FAS 0.40 average concrete compressive strength for STATPLA is 272.09 kg/cm2, STATPDA is 94.37 kg/cm2, SDATPDA (13%) was 237.18 kg/cm2 and SDATPDA (16%) was 249.18 kg/cm2. FAS 0.50 average concrete compressive strength for STATPLA was 238.83 kg/cm2, STATPDA was 74.05 kg/cm2, SDATPDA (13%) was 192.22 kg/cm2 and SDATPDA (16%) was 202.23 kg/cm2. These results indicate that there is an influence on FAS variations in concrete casting in brackish water with the addition of admixture.
