Abstract

Keterkaitan antara bangkitan perjalanan dan pertumbuhan penggunaan lahan merupakan suatu kajian yang tidak dapat terlepas dari eksistensi sistim transportasi secara menyeluruh. Sistem transportasi dan pengembangan lahan (land development) saling berkaitan satu sama lain, maka di dalam sistem transportasi, tujuan dari perencanaan adalah menyediakan fasilitas untuk pergerakan penumpang dan atau barang dari satu tempat ke tempat lain atau dari berbagai lokasi penggunaan lahan. Pengembangan lahan tidak akan terjadi tanpa adanya sistem transportasi, sedangkan sistem transportasi yang disediakan tidak bermanfaat apabila tidak melayani kepentingan ekonomi atau aktivitas pembangunan. Kajian yang mendalam mengenai analisis keduanya (transportasi dan penggunaan lahan) didasarkan data hasil pengukuran luas penggunaan lahan dan volume yang keluar dan masuk jalan tol Jakarta-Cikampek. Hasil analisa dari seluruh data yang diperoleh dari pengamatan di lapangan berupa fungsi linier dengan persamaan Y= 66, 895+0.323X2+12,660X4+2.061X5-0,779X6 untuk on ramp dan persamaan Y= 266,544+24,868X5-1,959X6+1,623X7 untuk off ramp

Abstract

Tingginya pengguna kendaraan pribadi menyebabkan kemacetan terutama di Daerah Khusus Ibukota Jakarta dari waktu ke waktu. Karenanya untuk melakukan perpindahan dari satu wilayah ke wilayah lain membutuhkan waktu lebih dalam melakukan perjalanan. Untuk mengurangi kemacetan pemerintah khususnya wilayah Jabodetabek sebisa mungkin memaksimalkan angkutan umum sebagai transortasi utama serta kesadaran masyarakat tentunya. KA Bandara merupakan moda transportasi umum di wilayah Jakarta-Tangerang yang termasuk moda baru untuk menuju Bandara Soekarno Hatta. Pertumbuhan penumpang KA Bandara pada empat bulan pada bulan Juli  hingga Oktober 2020 menunjukan peningkatan yang cukup signifikan. Pertumbuhan penumpang KA Bandara yang menunjukan data trend atau berjalan naik dapat mengindikasikan bahwa pada tahun berikutnya penumpang KA Bandara akan semakin meningkat. Bersamaan dengan meningkatnya pertumbuhan penumpang tersebut maka untuk kebutuhan perjalanan KA Bandara ikut bertambah. Peramalan dilakukan dengan model Trend Projection yaitu dengan membandingkan metode trend linear, exponential, dan trend parabolic. Untuk mengetahui kapasitas lintas pada lintas Manggarai – Bandara Soetta dilakukan perhitungan kapasitas lintas dengan menggunakan rumus kapasitas lintas versi Uned Supriyadi. Berdasarkan hasil analisis metode Linear dengan persamaan y = 4290,9x + 16561 , merupakan metode terbaik dengan nilai deviasi sebesar 7%, pada November 2020-Oktober 2021 jumlah penumpang sebanyak 739.385 penumpang. Perhitungan kebutuhan perjalanan pada KA Bandara dengan 40 perjalanan masih dapat memenuhi. Kapasitas Lintas eksisting lintas Manggarai-Bandara Soetta masih dapat memenuhi kebutuhan perjalanan, yaitu : Manggarai – Sudirman Baru 336 KA Sudirman Baru – Tanahabang 336 KA Tanahabang – Duri 403 KA Duri – Batuceper 201 KA Batuceper – Bandara Soetta 168 KA

Abstract

The area of DKI Jakarta has an area of ± 661.52 Km2, the City of DKI Jakarta is a swamp managed by 13 water channels that flow to the north of the island of Java, the development of water in DKI Jakarta is part of the way it is released into the sea by gravity and partly by the system. pump. Floods that occur every year in DKI Jakarta cannot be separated from the impact of the flow of water that crosses it. Very large waterways start in the southern part of DKI Jakarta, especially the Bogor area which has a height of more than 200 m above sea level and high rainfall, so DKI Jakarta is usually an area that collects water from its upstream river. The purpose of discussing this problem is to find out the amount of river flood discharge, find out whether the capacity of the river is able to accommodate flood discharge, find out how many pumps and how much pump capacity is needed in order to overcome flood discharge in the marina watershed. Thus, the conclusions obtained from the modeling results of the existing condition of the river's capacity are not able to accommodate flood discharge, therefore it is necessary to install a pump to cope with flooding in the DKI Jakarta Marina watershed using the Hec - Ras method.
