Abstract
Bus Transjakarata merupakan angkutan massal yang ber-
operasi pada sistem transportasi Bus Rapid Transit (BRT) di Kota
Jakarta, yang beroperasi pada rute dengan halte yang disediakan.
Banyaknya halte mengakibatkan bus sering melakukan pe-
ngereman. Dengan seringnya bus melakukan pengereman dan
didukung dengan massa bus yang besar, maka ada potensi energi
akibat perlambatan yang bisa disimpan (regenerative) untuk
digunakan lagi saat akselerasi. Jika hanya mengandalkan tenaga
dari engine untuk akselerasi, maka engine akan bekerja dengan
beban yang tinggi. Untuk mengurangi beban kerja engine saat
akselerasi, dapat dibantu menggunakan regenerative braking
melalui putaran flywheel.
Untuk dapat menganalisa regenerative braking pada Bus
Transjakarta maka digunakan beberapa parameter seperti data
teknis spesifikasi kendaraan, driving cycle, regulasi pe-ngereman
ECE (Economic Commission for Europe), gaya hambat kendaraan
dan FBD pengereman kendaraan. Parameter ini digunakan untuk
mengetahui peta distribusi pengereman kendaraan Bus Trans-
jakarta, porsi pengereman baik untuk regenerative braking mau-
pun mechanical braking serta mengetahui sebaran energi pengere-
man pada driving cycle terhadap peta distribusi pengereman
kendaraan tersebut.
Dari hasil analisa energi pengereman Bus Transjakarta,
didapatkan porsi regenerative braking roda depan sebesar 0.05g,
roda belakang sebesar 0.065g dan mechanical braking sebesar
0,04387g. Energi maksimum yang dihasilkan oleh regenerative
braking depan sebesar 963623J dan regenerative braking roda
belakang sebesar 1252710,5J. Dengan pertimbangan ketersediaan
ruang pada chasis Bus, maka flywheel yang digunakan memiliki
spesifikasi diroda depan : Dofw=0.4m, hfw=0,072m, mfw=68,58kg,
dengan putaran maksimum 11105,39rpm. Sedangkan spesifikasi
diroda belakang : Dofw=0.34m, hfw=0,131m, mfw=87,85kg, dengan
putaran maksimum 13065,165rpm. Untuk energi yang dapat
dipenuhi oleh regenerative braking sebesar 41,37% dari kebutu-
han energi total saat akselerasi
Transjakarta a mass transit system that operates at the
transport Bus Rapid Transit (BRT) in Jakarta, which operate on
routes with stops provided. The number of bus stops resulting in
frequent braking. With frequent bus braking and supported by a
large mass of the bus, then there is the potential energy that can be
saved as a result of deceleration (regenerative) to be used again
during acceleration. If only rely on power from the engine to the
acceleration, the engine will work with high load. To reduce the
workload of the engine during acceleration, can be assisted
through the use of regenerative braking flywheel rotation.
To analyze regenerative braking on TransJakarta bus then
used several parameters such as technical data specification
vehicles, driving cycle, braking regulation ECE (Economic
Commission for Europe), drag the vehicle and the vehicle braking
FBD. This parameter is used to determine a map of the distribution of the vehicle's braking Bus Busway, good braking portion
for regenerative braking and mechanical braking and know the
distribution of braking energy in the driving cycle to braking re-
gion of vehicle.
From the analysis of TransJakarta bus braking energy,
obtained regenerative braking portion of 0.05g front wheel, rear
wheel of 0.065g and mechanical braking of 0,04387g. Maximum
energy generated by front regenerative braking are 963623J and
rear regenerative braking are 1252710,5J. In consideration of the
availability of space on bus chassis, the flywheel is used has a
front wheel specifications:Dofw=0.4m,Hfw=0,072m, Mfw=68,58kg,
with maximum rotation 11105,39rpm. While the rear wheel
specifications : Dofw=0.34m, Hfw=0,131m, Mfw=87,85kg, with
maximum rotation 13065,165rpm. For energy can be met by
regenerative braking for 41.37% of the total energy during
acceleration.
