Abstract

The use of a Hybrid Electrical Energy Storage System (HESS) using a battery and supercapacitor in regenerative braking system on BANGKITS E-Trail prototype has the potential to offer greater power density and cycle life. The aim of the study was to maximize the recovery of energy during braking using the system, while improving the performance of E-Trail BANGKITS. The proposed regenerative braking system based on HESS was designed and fabricated while considering energy recovery capacity, and maximum electsamarical load. After fabrication, the system was tested for its efficiency, in energy recovery and to drive the vehicle using recovered energy. The tests were conducted in two steps, which are stationary, and dynamic tests, using a variation of motor and vehicle speed. The results of the tests showed in regenerative mode, system can recover up to 4410 J of energy with 41% efficiency with ascending trend as motor speed increases, while in drive mode, system can successfully drive the vehicle at 1430W power draw, and 14.8s of discharge time. In vehicle performance test, system was capable of generating braking force of 427.92N at 36% braking contribution. System can also extend the driving range of the vehicle by 2.4% of test route distance.

Abstract

Pinisi tourist ship is one of the tourist ship designs made to increase the interest of tourists to come to Taka Bonerate National Park. This tourist destination presents excellent maritime beauty, especially its coral reefs. Just like ships in general, pinisi also requires a supply of electricity, especially for use in lighting on board. This research aims to analyze the need for lighting power on board, by carrying out the concept of a tourist ship, the lighting system is also made like in a hotel with the aim of pampering tourists. In planning, the lighting system is made into two conditions, namely conditions during sleep and normal conditions. The type of lamp used is an LED lamp which is proven to be better than other types of lamps. The method used is the zonal cavity method or usually called the lumen method. The advantage of this method is that the power of the lights used in the room will be just right according to the needs of the room, neither more nor less, so it won't interfere with your eyesight because the lights don't feel dim or too bright. The results obtained were the following values for each Junction Lighting (JL), bottom deck (JL1) obtained a value of 0.419 kW, main deck (JL2) obtained a value of 1.058 kW, upper deck (JL3) obtained a value of 0.893 kW. The calculation value for the Junction Emergency (JE) was also obtained at 0.506 kW.

Abstract

In this work, we model temperature evolution inside a batch type rotary dryer by using the bond-graph method. The evolution model proposed here is mainly developed to predict dried material temperature inside the dryer during drying process. We implement the model in the 20-SIM bond-graph simulator (Controllab Products, the Netherlands) which shows realistic behaviors of the dried material temperature evolution with different combustion scenarios and rotation speeds.

Abstract

Aerodynamic forces affect the stability of a car when moving, especially when turning. This study conducted a CFD analysis of the influence of wings on the student formula car when turning. The addition of front and rear wings to the formula car increases drag, downforce, and side forces. Except for an airplane that is landing, large drag forces are always avoided, as well as side forces that can interfere with vehicle stability. Interestingly, in contrast to drag and downforce, the coefficient of side forces tends to decrease as cornering speed increases. The increase in downforce or negative lift in this formula car is more dominant and significant than that in the others, and it is very beneficial in increasing wheel grip and traction on the car’s stability when turning
