Abstract

Number (PCN) sebesar 83 F/C/X/T. Saat ini Bandara Internasional I Gusti Ngurah Rai-Bali, melayani beberapa tipe pesawat udara, salah satunya adalah pesawat Boeing 777-300ER yang memiliki Aircraft Clasification Number (ACN) sebesar 86. Nilai ACN yang lebih besar dari PCN ditengarai sebagai salah satu penyebab terjadinya kerusakan dan menurunnya daya dukung runway. Kajian kondisi perkerasan eksisting dan perencanaan untuk meningkatkan nilai PCN runway diperlukan untuk dapat melayani operasional sejenis pesawat Boeing 777-300ER sampai 10 tahun ke depan. Data-data yang dikumpulkan sebagai parameter dan variabel dalam menentukan kondisi dan merencanakan perkerasan runway yaitu persentase jenis dan persentase kerusakan, tebal lapis perkerasan runway, Nilai California Bearing Ratio (CBR), karakteristik pesawat udara dan annual departure. Hasil analisa menggunakan software FAARFIELD dan COMFAA mendapatkan Pavement Classificasion Index (PCI) runway Bandara Internasional I Gusti Ngurah Rai-Bali adalah 65,83 termasuk kondisi cukup (fair). Kondisi ini mengindikasikan bahwa runway Bandara Internasional I Gusti Ngurah Rai-Bali dalam keadaan kelelahan (fatique). Hasil analisis juga mendapatkan, untuk meningkatkan daya dukung runway sehingga mampu melayani pesawat sejenis Boeing 777-300ER sampai 10 tahun ke depan (sampai Tahun 2030), diperlukan tebal lapis tambahan (overlay) 10,41 cm. Overlay senilai tersebut menjadikan Bandara Internasional I Gusti Ngurah Rai-Bali memiliki runway dengan PCN 121 F/C/X/T.

Abstract

The need for the use of concrete raw materials is increasing in line with the increase in the use of concrete in construction. The availability of concrete raw materials is dominated by the exploitation of natural resources, namely components of cement, sand and crushed stone or gravel. If the availability of this material is exploited in excess, it will have an impact on environmental damage. On the other hand, many stone crafts for decoration and building ornaments in Bali also utilize tabas stone which is also exploited from nature, where the processed rock leaves a lot of waste that is disposed of without any wise processing actions. Tabas stone waste management is expected to maximize the utilization of natural resources and also reduce environmental pollution caused by the disposal of tabas stone waste that is not managed properly. This research is expected to provide an alternative to maximize the use of tabas waste as a partial substitution of crushed stone or gravel as coarse aggregate in concrete mixtures. The porous structure of tabas stone and the high level of water absorption in the concrete mix can reduce the compressive strength of the concrete. Steps to reduce water absorption in tabas stone are carried out by maximally closing the pores using a polyester resin coating. The study was carried out by making normal concrete mixture objects according to SNI 03-2834-2000. The percentage of substitution of crushed stone with waste stone that is coated with polyester resin is 0%, 25%, 50%, 75%, 100% of the required weight of coarse aggregate. The compressive strength of the concrete will be tested at the age of 7 and 28 days using a cylindrical specimen measuring 150x300mm. Test results in the laboratory showed that the coating of tabas stone using polyester resin was able to reduce the level of water absorption from 9.96% to 3.24% or 67.5% compared to tabas stone that was not coated with polyester resin. The optimum compressive strength of coarse aggregate substitution using tabas was obtained at variations of 50% crushed stone 50% tabas stone at the age of 7 days and 28 days, respectively, reaching 15.06 MPa and 21.55 MPa.

Abstract

Making a bar bending schedule is one of the efforts to control the waste material of reinforcing steel, but in calculating the waste material manually it is still not optimal. In order to reduce the waste material, it is attempted to use software namely Cutting Optimization Pro (SCOP) which produces the output in the form of the most optimal pattern of cutting of reinforcing steel. The research object for the Villa Stilo Development Project was chosen because in the concrete structure work process there was quite a lot of steel material left over. The purpose of this study is to determine the needs and total costs, the percentage of waste and the waste cost of steel reinforcement. The method used is descriptive analytic, with the data used in the form of working drawings and budget plans. The need for steel is calculated using Bar Bending Schedule (BBS) method, for the waste of the material is analyzed using manual calculations (conventional) and compared using SCOP. The results of the analysis showed that the need for reinforcing steel in the Villa Stilo Development Project was 1,205 rods of Ø8 steel, 103 rods of Ø10 steel, 75 rods of D10 steel, 882 rods of D13 steel, 21 sheets of M7 wiremesh and 18 sheets of M10 wiremesh. With a total cost of steel needs of Rp. 225,937,460.00. The percentage of waste generated by using the conventional method is 9.43%, while using SCOP is 4.36%. For waste costs using the conventional method of Rp. 19,937,700, while using SCOP of Rp. 9,693,760.00 or the waste cost using the conventional method is 105.68% bigger than using SCOP.
