Abstract

This research was conducted to test the comparison of compressive strength of concrete using Tonasa cement and Conch cement. Remembering that cement is the most important material in making concrete. So many people use Portland cement in making concrete. The aim of this research is to determine the compressive strength of concrete that is good for use in construction work. In this research, Tonasa cement and Conch cement were used to determine the compressive strength of concrete at the age of 3 days and 7 days in the Ambon State Polytechnic laboratory, civil engineering department. With 12 cylindrical test objects with a diameter of 15 cm and a height of 30 cm. The method used in this research is an experimental method, to investigate the relationship between the compressive strength of compression testing machine concrete and the hammer test number test. the result showed that the  average compressive strength is : Tonasa cement was 41.52 Mpa for cylindrical concrete, 500.23  for cube concrete at 3 days old and 28.16 MPa for cylindrical concrete, 339.32  for cube concrete at 7 days and Conch cement of 38.92 Mpa for cylindrical concrete, 468.97  for cube concrete at 3 years of age. days, and 26.86 MPa for cylindrical concrete, 323.58  for cube concrete at the age of 7 days.

Abstract

This condition causes the asphalt mixture to be unable to be overlaid on the road work site because the temperature of the mixture is below the overlay and compaction temperature. According to the provisions of the asphalt mixture that has experienced a decrease in temperature can no loger be used. But the reality that happens a lot in the field is that sanding is still done and followed by the next stage, namely compaction. Therefore, it is necessary to conduct research on the effect of heating on the concrete asphalt layer mixture, namely hot rolled sheet-Base (HRS-Base). The method used, the effect of AC-WC asphalt mixture temperature on the specific gravity of road work is . From yhe results of the marshall analysis, the value of marshall parameters that meet the requirements is in the range of asphalt content 4.50-5.80 so that the optimum asphalt content is obtained at the middle value of the limit range above is 5.12%. Comparison of asphalt temperature to field temperature and lab asphalt temperature. The asphalt temperature in the lab is 5.5% asphalt content and the asphalt temperature used in the lab is 160°C, 150°C, 140°C, 130°C, while the asphalt content used in the field is 5.0% asphalt content and the asphalt temperature used in the field is 125°C, 135°C, 140°C, 145°C. Further research needs to be carried out in the form of marshall soaking tests with the intention of measuring the durability of the binding/adhesion of asphalt mixtures to the influence of temperature.

Abstract

Penelitian ini membahas penyusunan Rencana Anggaran Biaya (RAB) dan jadwal pelaksanaan pekerjaan pada ruas Jalan Philip Latumahina, Kota Ambon. Tujuan penelitian ini adalah untuk mengetahui estimasi biaya proyek serta menyusun jadwal pelaksanaan pekerjaan secara sistematis sebagai acuan perencanaan. Metode yang digunakan adalah deskriptif kuantitatif dengan memanfaatkan data primer dan sekunder, berupa hasil observasi lapangan serta dokumen proyek. Penyusunan RAB dilakukan berdasarkan analisis harga satuan pekerjaan dengan mempertimbangkan volume pekerjaan, tenaga kerja, material, dan peralatan. Sementara itu, jadwal pelaksanaan disusun menggunakan metode bar chart (Gantt chart) untuk menggambarkan urutan dan durasi kegiatan. Hasil penelitian menunjukkan bahwa estimasi RAB memberikan gambaran kebutuhan anggaran yang realistis dan dapat digunakan sebagai dasar dalam perencanaan serta pengendalian biaya proyek. Jadwal pelaksanaan menunjukkan durasi total pekerjaan sekitar 26 hari dengan tahapan kegiatan yang tersusun secara logis. Dengan demikian, integrasi antara perencanaan biaya dan penjadwalan dapat meningkatkan efisiensi dan pengelolaan proyek, serta dapat dijadikan sebagai referensi awal untuk proyek konstruksi jalan sejenis di masa mendatang.

Abstract

Arung Samudra Bahari, Nim 1319174057 “the effect of resin as an addition to Asphalt concrete - binder course (AC-BC) mixture on marshall characteristics”. Thesis, Road and Bridge Construction Engineering Study Program, Department of Civil Engineering, Polteknik Negri Ambon. This thesis is under the guidance of David Daniel Marthin Huwae. S T., MT. and Penina T. Istiah, S Pd., M. Si. In the resin tree there is sap which contains essential oils and there is also resinol acid which has sticky, hard, and also melts easily. The resin will harden and then melt again depending on certain temperature changes. The effect of adding rosin sap to the asphalt mixture proves that the characteristics of asphalt are not much different from proving asphalt in general, but the results obtained on asphalt combined with rosin sap have increased elastic power which still maintains the unity of its shape due to high pressure. The use of resin can make asphalt mixtures more able to withstand road damage due to changes in weather and climate, the purpose of this study is to analyze the characteristics of Asphalt Concrete - Binder Course (AC-BC) levels in the presence of added resin and analyze the comparison between the addition and without the addition of resin to the Asphalt Concrete-Binder Course (AC-BC) mixture on marshall characteristics using 2% and 3% resin levels. As carried out in the Laboratory of the Maluku Ambon Road Implementation Center with reference to the requirements published by the Directorate General of Highways at KAO. The data collection method used in this study is the collection of primary data obtained based on several test objects from various treatment conditions tested in the laboratory such as marshall test results which include density, VIM (void this mix), VMA (void this mineral aggregate), VFA (void filled with asphalt), stability, flow (melting), and MQ (marshall quotient). And secondary data obtained from literature studies. The overall test results that meet the requirements in the 3% resin mixture with 5%, 5.5%, 6% asphalt content meet the specification requirements that have been listed with the 2018 bina marga specifications. So it can be concluded that the greater the presentation of resin content, the higher the quality value.

Abstract

The Piru-Loun road section of West Seram Regency has a road width of 6m and a road length of 9.35km. The road damage that occurred was 4.35km long starting from STA 5+000 - 9+350. The damage that occurs is that the surface experiences deformation, grain release, cracks, and even holes, the potholes in the road have reached the pavement foundation layer and some even have visible subgrade layers. Technically, road damage indicates a condition where the road is structurally and functionally no longer able to provide optimal services for traffic activities. The aim of this research is to determine the damage and condition of the road, compare the thickness of the flexible pavement overlay and plan the budget (RAB). Damage analysis uses the Bina Marga method and in planning the thickness of the added layer (Overlay), the 1993 Aashto method and the 2017 Road Pavement Design Manual method, which are planning methods for determining the thickness of Indonesian standard pavement layers, the differences between the two flexible pavement methods (Flexible Pavement) will be shows which method is more efficient in application at the damage location. The results of the damage analysis show a priority order value of 5, included in the periodic maintenance program. The result of the added layer thickness using the 2017 Road Pavement Design Manual method was 2.5 cm and the 1993 Aashto method was 5.4 cm. The results of the analysis of the Cost Budget Plan for an added layer thickness of 5.4 cm amounted to IDR 973,858,542.62
