Abstract

Regenerative breaking is an energy recovery mechanism from wasted energy during breaking process. In a conventional breaking process, the kinetic energy from the wheel is converted into heat due to friction of the break disc.  In regenerative breaking, the kinetic energy is converted into electric energy by a dynamo. This research aims to find amount of electric power, voltage and current that can be generated from regenerative breaking. By adding a prototype which contains dynamo of bicycle, rectifier and dc-dc converter, the generative braking can change kinetic energy into electrical energy. In this research, three types of front wheel disc, i.e. with hard insulation, soft insulation and without insulations had been used for the experiment.. It is found that the best result is obtained by using hard insulation. For motorcycle speed at 70 km/hours, voltage, current and power values are 12,8 Volt, 130 mA and 1664 mWatt. The advantages of the hard insulation are less friction,  less heat dissipation and  quieter.  Keywords : Regenerative braking, motorcycle, isolation, wheel, dynamo of bicycle.

Nowadays, the wind energy research for alternatif anergy has been progress. Wind energy can be found if the wind turbine is available. Based on rotation axis, wind turbin has been classified to Horizontal Axis Wind Turbine (HAWT) and Vertical Axis Wind Turbine (VAWT). This paper explains  simple HAWT prototype to 200 ohm resistor and LED at small scale wind speed. The blade material is acrilic. This material property is light, no easy broken, no corrosive and easy to find it. The blade model is flat plate section. Rotor diameter is 1 meter. The research was did at the beach. Permanent magnet synchronous generator is used to change wind energy to electric energy. The result shows that the generator increase linearly with wind speed. Measured wind speed was 1.9 m/s to 3.9 m/s. Average efficiency of HAWT prototype was 6.2% at delta connected load and 3.7% at wye connected load.

Abstract

False alarm in fire detection can cause a huge loss. False alarm is generated by unwanted signal of smoke detector such as outdoor smoke or smoking. Therefore, it is designed a system that can reduce false alarm. The purposed system is built based on three components, those are sensors, actuators and data communication. Sensors are smoke, flame and camera sensor. Smoke sensor is used as the first thing to sense a signal from the system that warns the system there is a fire. Flame sensor and camera are used to confirm that a signal of fire whether false alarm or not. Internet of Things (IoT) is applied to control the system. The result show that the system is applicable.

Abstract

The Vertical Axis Wind Turbines are very suitable for use in areas with very low wind speeds. This research makes a prototype of the Savonius wind turbine to produce electrical energy as an energy source to 2 x 3.7 Volt dry battery. The Savonius turbine has four blades made of PVC. The controller circuit consists of a Boost Converter circuit and an astable multivibrator. At a speed of 2.7 m/s, the wind turbine starts to rotate and produces a no-load voltage of 0.3 V. At a speed of 3.7 m/s a voltage of 2 V is generated and can charge the battery. By using an LED (Light Emitting Diode) in the controller circuit, the charged battery can be a source of voltage in the controller circuit and the LED indicator light can be lit.

Abstract

Increasing energy efficiency in the cement production process at PT Semen Padang is carried out by reusing exhaust gas to produce electricity using Waste heat recovery power generation (WHRPG) with a capacity of 8.5 MW. WHRPG is a technology for utilizing exhaust gas heat as a source of heat energy to heat feed water into steam by using a suspension preheater (SP) boiler and air quenching cooler (AQC) boiler. This study aims to calculate the power potential of the steam heat influenced by the steam temperature and the mass flow rate of the steam produced by the boiler, to calculate the efficiency of the boiler using the direct method by comparing the boiler output heat against the boiler input heat, to calculate the turbine efficiency based on the difference between the steam enthalpy enter the turbine against the steam enthalpy out of the turbine and the isotropic enthalpy of the steam out of the turbine and to calculate the power generated by WHRPG at PT Semen Padang. The results obtained in this study are the total potential power of steam heat is 19.778 MW, the boiler AQC efficiency is 70.30%, the boiler SP efficiency is 94.04% and the turbine efficiency is 78.64%. The electricity generated by PT Semen Padang's WHRPG is 3.70 MW.

Abstract

Microbial Fuel Cell (MFC) is one tool that uses microbes to produce electrical energy. The main components of MFC support are anodes, cathodes, and salt bridges. In this paper, the application of tropical fruit waste to MFC is presented. Tropical fruit waste used here are pineapples, oranges, bananas, watermelons, mangos, and papayas. The fruit waste is extracted and fermented to produce microbial. The microbial produces ions attached to the anode. Measurement of system current and voltage is carried out using a digital multimeter. In pineapple substrate MFC, Voc has a maximum of 485 mV, maximum current density is 163 mA/m2 and maximum power density of 11mW/m2. The orange substrate obtained Voc maximum of 805 mV, maximum current density of 661 mA/m2 and maximumpower density of 62 mW/m2. Voc banana substrate has a maximum of 312 mV, maximum current density of 118 mA/m2 and maximum power density of 5.9 mW/m2. The Voc watermelon substrate has a maximum of 451 mV, maximum current density of 306 mA/m2 and maximum power density of 18.6 mW/m2. Voc mango substrate has a maximum of  586 mV, maximum current density of 229 mA/m2 and maximum power density of 4.3  mW/m2. Voc papaya substrate is a maximum of 338 mV, maximum current density of 58 mA/m2 and maximum power density of 2.9 mW/m2. These results show the potential for renewable electricity sources.
