Abstract

Jalan Tol Cisumdawu merupakan salah satu proyek strategis nasional yang menghubungkan daerah Cileunyi-Sumedang dan Cirebon daerah Dawuan. Pada Jalan Akses Rancakalong Sta. 0+675 – 0+775 yang merupakan rangkaian pembangunan jalan tol Cisumdawu, berada pada tata guna lahan palawija dan dalam arah memanjang jalan lokasi ini merupakan daerah cekungan. Namun merujuk pada gambar desain konstruksi pada Sta. 0+675 – 0+700 merupakan daerah timbunan cukup tinggi dan tanpa perkuatan. Penelitian dilakukan untuk mengetahui stabilitas desain timbunan berdasarkan faktor keamanan dari timbunan menggunakan metode elemen hingga. Hasil yang didapatkan pada penelitian ini didapatkan pada kaki timbunan sebelah kiri diperkuat dengan kombinasi bored pile dengan dinding beton kantilever sedangkan pada kaki timbunan sebelah kanan diperkuat dengan kombinasi bored pile dengan gabion. Dengan perkuatan timbunan tersebut didapatkan nilai faktor keamanan timbunan sebesar 1.38.

Abstract

Prof. KH Anwar Musaddad is located in the Garut City area, West Java Province, which is a connecting road between Banyuresmi District and Tanjung Kamuning District. Due to the large amount of damage on Jalan Prof. KH. Anwar Musaddad who set the goals for this research. The purpose of this research is to identify soil characteristics, analyze and classify soil types. The research method used is a quantitative experimental method. Tests carried out are by testing in the field and laboratory. Testing in the field, namely by sondir test and laboratory testing includes physical and mechanical properties of the soil. Testing of the physical properties of the soil includes water content, specific gravity, Atterberg limits and sieving analysis. As for testing the mechanical properties of the soil, it includes direct shear strength testing. The results obtained from this study indicate the type of soil in Jalan Pro. KH. Anwar Musaddad is a sandy soil with the USCS classification in the SP and SC groups, while the AASHTO classification is in the A-3 and A-2-7 groups.

Abstract

In the current development of concrete innovation technology, there are also expensive materials that are cheap as concrete additives for the efficiency of the cost of making concrete. cheap and can be used as concrete innovation. The purpose of adding palm fiber fiber is to improve the quality of concrete, both compressive strength and split tensile strength. The method used in this study was experimentation by adding palm fiber to the SCC concrete mixture with variations of 2%, 4% and 6%. As for the addition of chemical substances, the superplasticizer admixture aims to make it easier for SCC concrete to achieve a slump flow value that meets the requirements. After testing, the highest compressive strength test specimen is BC 1 2% palm fiber worth 19.38 MPa and for the lowest compressive strength test is BC 2 6% palm fiber worth 5.46 MPa. And for the split tensile strength test the highest is BC 4 2% palm fiber worth 9.47 MPa and for the lowest split tensile strength test is BC 3 6% palm fiber worth 5.82 MPa.

Abstract

Self-compacting concrete (SCC) is self-flowing concrete that can be printed on formwork with very little or no compaction. One of them is by adding admixture superplasticizer. The purpose of this research is to determine the effect of superplasticizer admixture with various variations on flexural strength. The method used in this research is the experiment of adding superplasticizer admixture to the concrete mixture with variations of 3%, 4% and 5%. The sample was made of 3 test objects in the form of blocks with dimensions of 15 cm x 20 cm x 100 cm for a design value of 15 MPa. Based on the results of the flexural strength test of concrete beams after 28 days of flexural strength testing, the highest yield was obtained in the second sample of 4% mixture with a maximum P load of 32.2 KN after converting to 18.22 MPa. Whereas for the 1st sample it was a 3% mixture with a maximum P load of 22 KN after converting to 12.44 MPa and for the 3rd sample it was a 5% mixture with a maximum P load of 22.9 KN after converting it to 12.95 MPa. 3. It was found that the average of the 3 samples was 14.54 MPa, a little more to exceed the target of 15 MPa.
