Abstract
Mobil perkotaan merupakan salah satu jenis transportasi yang diproduksi untuk memenuhi kebutuhan mobilitas masyarakat di dalam kota maupun jarak jauh dengan waktu tempuh relatif lama. Terdapat berbagai kondisi yang dapat mempengaruhi tingkat kenyamanan berkendara bagi pengemudi, salah satunya penambahan jumlah penumpang. Penambahan jumlah penumpang menyebabkan perubahan posisi center of gravity yang berpengaruh pada respon dinamis dan transient kendaraan.
Dalam penelitian ini, dilakukan simulasi melalui pemodelan sistem satu kendaraan Mobil Kijang Innova Zenix HEV Q Hybrid Modellista sebagai objek penelitian. Tahap awal dalam penelitian, dilakukan perhitungan posisi center of gravity secara horizontal dan vertikal dengan menghitung gaya reaksi yang terjadi pada ban depan dan belakang. Posisi center of gravity setiap variasi jumlah penumpang digunakan sebagai parameter pengujian dalam simulasi menggunakan MATLAB. Sebagai input simulasi, digunakan dua profil jalan yaitu sinusoidal sebagai representasi jalan perkotaan dan impuls berupa bump berderet.
Hasil perhitungan dan simulasi menunjukan bahwa penambahan jumlah penumpang Mobil Kijang Innova Zenix HEV Q Hybrid Modellista menyebabkan center of gravity bergeser ke belakang dan ke atas untuk menjaga keseimbangan mobil selama berkendara. Posisi center of gravity paling belakang berada sejauh 1,42 m dari ban depan dan 1,43 m dari ban belakang dengan total massa penumpang 525 kg. Semakin jauh jarak pengemudi dari center of gravity, momen torsi yang dihasilkan semakin besar sehingga menurunkan kenyamanan pengemudi selama berkendara. Dengan input jalan sinusoidal, nilai RMS percepatan paling tinggi pengemudi yaitu 0,177 m/s^2 pada kecepatan 80 km/jam sehingga pengemudi hanya dapat bertahan selama 16 jam sesuai standar ISO 2631. Dengan input jalan impuls, terjadi peningkatan peak value pengemudi. Peak value percepatan tertinggi pengemudi adalah 0,122 m/s^2 dan perpindahan sebesar 0,00709 m.

A city car is one type of transportation that is produced to fulfill the mobility needs of people in the city and for long distances with relatively long travel times. There are various conditions that affect the level of driving comfort for the driver, including the number of passengers. Adding passengers causes a change in the position of the center of gravity, affecting the vehicle's dynamic and transient responses.
This study employs simulation through the modeling of a full-vehicle system of the Kijang Innova Zenix HEV Q Hybrid Modellista as the object of research. The initial stages of the research, calculating the horizontal and vertical center of gravity positions by determining the reaction forces acting on the front and rear tires. The center of gravity positions for varying passenger loads used as test parameters in simulations using MATLAB. Two road profiles are utilized as simulation inputs: sinusoidal, representing urban roads, and impulse, in the form of a series of bumps.
The analysis of simulation data reveal that increasing the passenger load in a Kijang Innova Zenix HEV Q Hybrid Modellista shifts the center of gravity rearward and upward to maintain vehicle balance while driving. With a maximum passenger mass of 525 kg, the center of gravity was located 1.42 m from the front axle and 1.43 m from the rear axle. This shift affects the driver's distance from the center of gravity, leading to increased torque moment generation and potentially affecting driver comfort. With sinusoidal road input, the driver experienced a maximum RMS acceleration of 0.177 m/s at 80 km/hour. Based on ISO 2631 standards the driver can withstand the ride for only 16 hours. With impulse road input, peak acceleration values increased, reaching a maximum of 0.122 m/s² with a corresponding displacement of 0.00709 m.
