Abstract

Jalan yang berfungsi ganda sebagai parkir on street menyebabkan terjadinya pengu­rangan lebar efektif jalan. Keberadaan parkir di badan jalan di sekitar fasilitas putaran balik (U-turn) dapat menimbulkan konflik berupa kemacetan karena kendaraan yang melakukan putaran balik terganggu oleh adanya parkir di badan jalan. Penelitian ini bertujuan untuk mengetahui kinerja ruas jalan Affandi, Yogyakarta akibat adanya parkir di badan jalan pada lokasi U-turn dan memberikan solusi untuk meningkatkan kinerja ruas jalan akibat hal tersebut. Data primer didapatkan dari survei perhitungan kendaraan, kecepatan, geometri, dan driving behaviour. Analisis kinerja berdasarkan data primer, Manual Kapasitas Jalan Indonesia tahun 1997 (KemenPUPR) dan di modelkan dengan VISSIM. Hasilnya, kecepatan kendaraan rata-rata pada kondisi eksisting sebesar 25,44 km/jam, tingkat pelayanan E, dan derajat kejenuhan 0,81. Alternatif solusinya yaitu pemberlakuan larangan parkir pada area putaran balik dan beberapa meter sesudah dan sebelumnya. Hasil pemodelan VISSIM menunjukan, semakin jauh  larangan parkir dari lokasi u-turn, maka kinerja jalan semakin meningkat.

Abstract

The occurrence of changes in time and costs due to design changes and the addition of new work items affect the time and cost of implementing construction work. The addition of work items was also found in the construction of building A of the new school unit of SMPN 47 Padang. This is the impetus for conducting a time and cost analysis due to changes in building design and analyzing the index value of time and cost performance using the case study method and qualitative descriptive analysis. In the initial stage, identification of additional work items was carried out, then continued with an analysis of the time and cost using the Earned Value Analysis method. The results of data processing obtained the addition of new work items such as the board of directors, tree removal work, additional floors in buildings A and B so that they had an impact on the time and cost of implementation with an increase of 9.49%. Using the Earned value method, the SPI value was obtained with an average value of 0.798 and the CPI with an average value of 0.595. There was an additional implementation time of 25 calendar days and an additional implementation cost of Rp 1,016,937,031.14, - or an increase of 9.46%. The value and for SPI with an average value of 0.798 (<1) which indicates that the project is experiencing delays from the planned schedule, for CPI with an average value of 0.595 (<1) which indicates that the project's costs are greater than the budget.
