Abstract

Tanah dasar pada proyek pembangunan jalur ganda kereta api di KM 437+300 sampai KM 438+500 Gombong, Kebumen merupakan tanah lunak (N-SPT < 15) sehingga memerlukan upaya perbaikan tanah untuk menghindari terjadinya penurunan tanah melebihi penurunan tanah yang diijinkan, yaitu sebesar 20cm. Dalam penelitian ini direncanakan upaya perbaikan tanah dasar menggunakan Prefabricated Vertical Drain (PVD) untuk mempercepat proses pemampatan tanah akibat beban tanah timbunan badan jalan rel, beban konstruksi jalan rel, dan beban kereta api yang melintas. Hasil analisis pemampatan menunjukkan bahwa tanah dasar akan mengalami penurunan tanah sebesar 0,524m. Waktu konsolidasi alami yang dibutuhkan untuk mencapai derajat konsolidasi 90% adalah selama 268,9 tahun. Sedangkan, waktu konsolidasi untuk mencapai derajat konsolidasi 90% menggunakan PVD berjarak 0,8 m dengan pola segitiga dan segiempat adalah selama 15 minggu dan 18 minggu. Penanaman PVD pada kedua pola tersebut adalah sedalam 24 m

Abstract

The subgrade in the railway double track development project in KM 437 + 300 to KM 438 + 500 Gombong, Kebumen is soft land (N-SPT <15) so that it requires efforts to improve the land to avoid land subsidence exceeding the allowable land subsidence, which is equal to 20cm In this research, an effort to repair subgrade uses Prefabricated Vertical Drain (PVD) to accelerate the process of soil congestion due to the load of the railroad pile, the burden of railroad construction, and the burden of the passing railroad. Compression analysis results show that the subgrade will experience a land subsidence of 0.524m. The natural consolidation time needed to achieve a 90% degree of consolidation is 268.9 years. Meanwhile, the time of consolidation to reach a degree of consolidation of 90% using PVD spaced 0.8 m with a triangle and quadrilateral pattern is for 15 weeks and 18 weeks. Planting PVD in both patterns is as deep as 24 m

Abstract

Starting December 1, 2019, the Adi Soemarmo Solo Airport Train operates on the route Solo Balapan Station-Adi Soemarmo Airport, with a distance of 12.9 kilometers, and an average travel time of 20 minutes. The mobility of the movements can lead to the mode selection process. Mode selection is one of the models used in planning public transport transportation. The results of the calculation of the probability of displacement for the variable age and occupation of the respondent are variables that have a significant effect. After the final analysis was carried out with categorization for each variable age and occupation, the categories for each age (2) were obtained, namely 21-30 years old and age (3), namely 31-40 years old. For each category of significant work variables, namely the work of 1 student, the occupation of 3 BUMN, and the occupation of 4 private employees. The results of the probability calculation show that the older the respondent is, the probability has decreased as a person gets older, they will tend to prefer to use private vehicles because they are easier to move, safer, and faster than those who are younger and prefer to use public transportation. for mobility because it is more affordable and cheaper. Likewise with work, students / students have a higher probability than private and BUMN employees because their mobility intensity is not as frequent as private employees or BUMN.
