Abstract

The foundation is part of the lower structure that functions to transmit the superstructure load to the soil base which is strong enough to support it and is usually dominated by the allowable settlement limit, in order to avoid danger to the superstructure. This study aims to analyze the bearing capacity and settlement of driven pile using analytical methods and Finite Element Method using Plaxis software. This study compares variations settlement and axial bearing capacity of piles with 300 mm, 400 mm, and 500 mm diameter. Based on the results obtained, the bearing capacity of the driven pile with plaxis is 20.25 – 26.63% higher than the calculation using the Schmertmann method. In terms of settlement, the results obtained are 3.37 mm for the D 300 mm, 3.29 mm for the D 400 mm, and 3.21 mm for the D 500 mm. All three settlement are still within safe limits.

Abstract

This research aims to identify opportunities for modal selection between Feeder Train and Bandung Local KRD as a continuation mode for KCJB passengers from Padalarang Station to Bandung City. This research is aimed at prospective passengers of the Highspeed Railway Jakarta-Bandung (KCJB) who will later choose between the Feeder Train and the Greater Bandung Local KRD as the next mode of travel from Padalarang Station to Bandung City. The survey was carried out by distributing questionnaires online to 384 respondents and processed using the binomial logit method. It was found that based on the analysis results in BIOGEME 3.2.11, the probability attributes of cost, travel time and waiting time between trains/headway for both modes were obtained, the probability for choosing the KA Feeder is greater if the utility value is large and vice versa, the probability of selecting the KA Feeder is smaller if the utility value is small. The highest probability value for choosing the Feeder Train is 94% in scenario number 4, whereas in this scenario the probability value for the Greater Bandung Local KRD is the smallest, namely only 6%, therefore the Feeder Train Mode is a mode that has greater opportunities for the Jakarta Fast Train Bandung as an advanced mode of travel from Padalarang Station.

Abstract

Indonesia adalah negara kepulauan yang besar dengan total 13.466 pulau. Dengan begitu, setiap kepulauan di Indonesia memiliki garis pantai di setiap daerah atau pulau. Salah satu pantai yang berada di Kota Batam adalah Pantai Bahagia. Berdasarkan pengamatan, diketahui bahwa pantai ini mengalami masalah akresi pantai. Peristiwa ini dapat mempengaruhi lalu lintas ferry di dekat area pantai. Selain itu, pantai ini juga tidak memiliki struktur pengaman pantai. Hal ini menyebabkan pantai ini terancam oleh bahaya abrasi dan ombak di masa depan. Tujuan dari penelitian ini adalah untuk merancang struktur perlindungan pantai berdasarkan data relevan yang diperoleh. Struktur perlindungan pantai yang dirancang akan mencegah abrasi pantai yang terjadi semakin parah. Metode penelitian ini adalah metodologi kuantitatif, dan beberapa analisis data dilakukan seperti pembentukan angin mawar, metode admiralty untuk analisis pasang surut, analisis perubahan garis pantai dan model sistem titik untuk pemilihan struktur pantai. Hasil perhitungan dalam perancangan struktur Jetty adalah tinggi bangunan dermaga 4.574 m ~ 5 m dengan berat lapisan batuan adalah 97,08 kg. Lebar puncaknya adalah 4 m dengan lapisan pelindung selebar 3.845 m. Gaiter dibuat dengan lebar 1,69 m dan tingginya 5 m. Rencana anggaran yang diperlukan untuk membangun struktur adalah Rp2.332.200.000,-. Hasil penelitian ini dapat diterapkan di wilayah pesisir lain di Indonesia.
