Bandung is a tourist city with a panoramic view of the surrounding mountains that attract tourists both from within and outside the city, even from abroad. The people of Bandung love to show off their city and its beautiful surroundings. However, the city of Bandung is well known for its traffic and air pollution. This is where cable cars come into play. A cable car is a form of transportation that does not use the road. This is a huge advantage, as it can help solve many problems caused by traffic congestion, pollution, and accidents. In this undergraduate thesis, the power requirements calculation for the cable car system through physics and fluid mechanics is due to the consideration of aerodynamic drag, potential energy and rolling friction loss. In addition, utilising Matlab to code the maximum tension for cable type and size selection through the help of numerical analysis. Also, computational simulation through the use of Solidworks will conduct the stress analysis to save time and minimise human error in the calculation. Design D, referenced from a hook design from Hanover, Germany, has the highest safety factor due to the curve design causing the stress to be distributed more evenly across its surface compared with other designs with sharp corners causing it to be greater prone to breakage. The optimum cross section for the hook is bowtie-shaped as the failure causing stress in a hook is bending stress, and a bowtieshaped tends to match the stress profile caused by bending stress. The ideal speed for the cable car system is four m/s with a passenger capacity of 10 people per cabin and a total power requirement of 70.80 kW for the Northern Bandung cable car system. Galvanised 6x19 steel wire rope with IWRC is selected for the cable type for its rust-resistant properties and balance between strength and flexibility.
