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.

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.

Abstract

Palm shell is a waste from palm oil production which is shaped like a shell with a hard layer character that aims to protect the palm kernels. The addition of palm shells to concrete is an innovation and breakthrough in the more productive use of palm oil waste. In this study, the percentage of addition of palm shells was used, among others, 0%, 7% and 14% by weight of cement with variations in the cement water factor (FAS) of 0.35, 0.45 and 0.50. The test object used was a cube (15 x 15 x 15) cm with a total of 9 test objects for each FAS with a test time of 28 days. The results of the concrete compressive strength test obtained data for FAS 0.35, the average compressive strength for BTCS was 348.15 kg/cm2, BDCSA (7%) was 363.07 kg/cm2 and BDCSB (14%) was 302.90 kg/cm2. FAS 0. 45 the average compressive strength for BTCS was 292.59 kg/cm2, BDCSA (7%) was 303.20 kg/cm2 and BDCSB (14%) was 249.27 kg/cm2. FAS 0.50 average compressive strength for BTCS was 273.09 kg/cm2, BDCSA (7%) was 271.53 kg/cm2 and BDCSB (14%) was 219.47 kg/cm2. The test results show that the average concrete compressive strength is influenced by the cement water factor (FAS) and the percentage of addition of palm shells in the concrete mix.
