Abstract

Damage to the dradah-kedungpring road is not only caused by the number (volume) of vehicles that exceeds the capacity of the road, but in it is also related to various factors namely human factors and natural factors. overload is a condition of vehicle axle load exceeding the standard load used on the assumption of a pavement design or the number of operational trajectories before the planned life is reached, or often referred to as premature damage. The highway rigid pavement planning method created by the Department of Public Works, namely the Bina Marga Method, has not yet been able to apply its planning standards. In its maximum implementation in the field, it has weaknesses that result in premature damage to the road before reaching the planned life. In this final project will produce a rigid Pavement Thickness Planning on Dradah - Kedungring Road Using the 2002 Bina Marga Method, the thickness produced is a pavement thickness calculation with the actual vehicle load for traffic data in the pavement thickness calculation using data from the traffic survey results which exists. In the research that has been carried out on the planning of the rigid pavement thickness of the Dradah-Kedungpring road, a thickness of 24 cm is expected to provide a good service life in accordance with the expected age of the plan.Keywords: Pavement, LHR, CBR, Vehicle Load Overloading.Kerusakan pada jalan dradah-kedungpring tidak hanya disebabkan oleh jumlah (volume) kendaraan yang melebihi kapasitas jalan, akan tetapi didalamnya juga terkait berbagai faktor yaitu faktor manusia  dan faktor alam. beban berlebih (overload) adalah suatu kondisi beban gandar kendaraan melebihi beban standar yang digunakan pada asumsi desain perkerasan jalan atau jumlah lintasan operasional sebelum umur rencana tercapai ,atau sering disebut dengan kerusakan dini. Metode perencanaan perkerasan kaku jalan raya yang dibuat oleh Depatermen Perkerjaan Umum yaitu Metode Bina Marga teryata belum bisa di terapkan standar perencanaannya, Dalam pelaksanaan di lapangan secaramaksimal sehingga memiliki kelemahan yang berakibat pada kerusakan dini pada jalan raya sebelum tercapainya umur rencana. Pada tugas Akhir ini akan Menghasilkan Perencanaan Tebal Perkerasan Kaku Pada Ruas Jalan Dradah - Kedungpring Menggunakan Metode Bina Marga 2002”, tebal yang di hasilkan merupakan perhitungan tebal perkerasan dengan beban actual kendaraan untuk data lalulintas dalam perhitungan tebal perkerasan telah mengunakan data dari hasil survey lalu lintas yang ada. Dalam penelitian yang telah dilakukan pada perencanaan tebal perkerasan kaku jalan Dradah- Kedungpring didapat tebal sebesar 24 cm diharapkan dapat memberikan masa layan yang baik sesuai dengan umur rencana yang di harapkan.Kata Kunci : Perkerasan, LHR, CBR, Beban Kendaraan Overloading.

Abstract

In improving technological progress, the use of concrete as a building is very popular in Indonesia. Because it can utilize materials that are easily obtained such as crushed stone, gravel, sand, cement and water at a relatively cheap price. On a daily use basis often found in housing construction project workers who use waste water (Sewer Water) for concrete processing. This of course requires a closer inspection of the quality of the concrete produced. The data analysis method begins with the investigation of cement materials, coarse and fine aggregates. Mixing concrete using clean water (PDAM) as a reference and waste water (Sewer Water) from the Unisla flat building. From the analysis that has been done, it is obtained the results of the compressive strength test of concrete at the age of 7, 14 and 28 days by mixing clean water of 13.68 MPa, 18.51 MPa, 21.04 MPa, while the results of the concrete compressive strength test at ages 7, 14 and 28 days by mixing Wastewater (Sewer Water) at 9.99 MPa, 13.35 MPa and 15.36 MPa. Keywords : Wastewater, Concrete, Compressive Strength Dalam meningkatkan kemajuan teknologi, pemakaian beton sebagai bangunan sangat popular di indonesia. Karena bisa memanfaatkan bahan yang mudah diperoleh seperti batu pecah, batu kerikil, pasir, semen dan air dengan harga yang relatif murah.Pada penggunaan sehari-hari sering dijumpai pada pekerja proyek pembangunan rumah tinggal yang menggunakan air limbah (Air Selokan) untuk pengerjaan pembetonan. Hal ini tentunya memerlukan pemeriksaan yang lebih teliti terhadap mutu beton yang dihasilkan. Metode analisa data dimulai dengan penyelidikan bahan semen, agregat kasar dan halus. Pencampuran beton menggunakan air bersih (PDAM) sebagai acuan dan air limbah (Air Selokan) dari gedung rusunawa Unisla. Dari analisa yang telah dilakukan didapat hasil pengujian kuat tekan beton pada umur 7, 14 dan 28 hari dengan pencampuran air bersih sebesar 13,68 Mpa, 18,51 Mpa, 21,04 Mpa,  sedangkan  hasil  pengujian  kuat tekan beton pada umur 7, 14  dan  28  hari  dengan pencampuran Air Limbah (Air Selokan) sebesar 9,99 MPa, 13,35 MPa, dan 15,36 MPa. Kata Kunci : Air Limbah, Beton, Kuat Tekan

Abstract

This study aims to know and analyze how strong the influence of additional water hyacinth fiber to the compressive strength of the K-200 paving block. The method used in this study is the experimental method, with the comparison of mix design referring to the comparison of concrete quality mixture K-200 (SNI 7394-2008). The result is K-200 paving block decreases its compressive strength after given the mixture of water hyacinth fiber. The percentage of the lowest decrease is in the 0,2 mixture of 55,69% and the highest decrease is in the mixture of 0,8 with the declining percentage of 82,39%.

Abstract

Based on the various properties of concrete, it is necessary to investigate the effect of mixing time of concrete mixture on the compressive strength of concrete. The length of stirring of the concrete mixture in question is the amount of time spent mixing the concrete in minutes. The experiment was performed using a concrete mixing machine with stirring times of 5, 10, 15, 20, 25, and 30 minutes. The method of data analysis begins with the investigation of cement, coarse and fine aggregates. The experiment was conducted at the laboratory of Lamongan Islamic University, using molen machine for mixing concrete and test specimens in test with concrete compressive strength test. From concrete compressive strength test, concrete compressive strength with rotation time for 5, 10, 15, 20, 25 and 30 minutes were 15,366 MPa, 17,021 MPa, 15,839 MPa, 15,603 MPa, 16,076 MPa, 15,603Mpa at age 28 days. Based on the test, the highest compressive strength of concrete was obtained on stirring for 10 minutes with a compressive strength of 17,021 Mpa or 16.872% of normal concrete.
