Solar panels or solar cells are one of the renewable energy sources. Solar cells can convert sunlight into dc electrical energy. However, the main problem with solar cells is that the energy produced is not stable. The surface of the Solar cell board has a maximum temperature which affects the output of the solar cell. From this research, the writer will make the surface cooling of the solar cell board using a heatsink fan. The maximum surface temperature of the solar cell board reaches an average of 45 oC. If the temperature exceeds 45 oC it will reduce the output of the solar cell. In this study, the average temperature on the surface of the solar cell board, from 9 am to 3 pm was around 50.14oC and the average output of the solar cell reached 18.80 Volts. Meanwhile, the average temperature of the solar cell with the use of heatsink cooling is 36oC. The average output of the panel is 19.11 volts. Thus, by using a solar cell surface board cooling system using a heatsink, it has an average temperature decrease of 28.20% and an increase in output (Output) can be increased by 1.64% from the efficiency of the Solar cell which is only 12.1%.

The Generator Set consists of the Engine (Motor Propulsion) and also the Generator / Alternator, as previously explained. This engine uses fuel in the form of Diesel (Diesel Engine) or can also use Gasoline, while the Generator itself is a coil of wire made of copper consisting of a static coil or stator and is also equipped with a rotating coil or rotor. In the process of working, according to physics, the engine rotates the rotor in a generator which then causes a magnetic field in the coil section of the generator. Furthermore, this magnetic field will then interact with the rotor which will then rotate and will produce an electric current which is in accordance with Lorentz's law.

Indonesia's electricity demand is predicted to increase every year, this can cause Indonesia to become an energy importer in the coming year. These problems can be overcome by developing alternative energy, one of which is by utilizing waste vibration energy or pressure energy from the movement of motorized vehicles, cars and pedestrians and even wind gusts in the use of piezoelectric speed bumps. Piezoelectricity is an energy harvester. Piezoelectric with cantilever mechanism produces vibration and deflection repeatedly, causing an electric voltage. The piezoelectric speed bump designed in this study consists of a speed bump system that serves to receive input from motorized vehicle pressure, piezoelectric cantilever system as a component producing electrical energy and energy harvesting system as energy harvester from piezoelectric materials. One system module consists of a parallel piezoelectric circuit connected to the MB39C811 buck converter. This paper will discuss the mechanism of design analysis and modeling of a piezoelectric power generation system on a body bluff-based speed bump with a cantilever system for variations in motor vehicle speed by means of physical modeling. In the piezoelectric bump bluff body, it can be seen that the air flow when passing through the triangular cross section increases in speed so that the resulting vortex has a high speed. This is what causes high vibrations in the piezoelectric so that the maximum voltage and the average voltage have the highest values. The piezoelectric speed bump is capable of generating electric power with an input of 60 times that of a motor vehicle above 2.166mWh with an efficiency of 2.

Direct torque control(DTC) of the induction motor is inclined to a specified value of torque. The torque provided is a speed output regulator, therefore it is mandatory to continue tuning to adjust the Kp, Ki parameters. In conventional proportional-integral (PI) speed controllers, motor performance may differ over time which may lead to torque disturbance uncertainty, causing sluggishness of the flux response so the choice of PID parameters is important for DTC systems. In this paper we present a control technique using Particle Swarm Optimization (PSO) to improve the parameters (Kp, Ki) of the speed controller to reduce torque ripple, stator flux distortion ripple and fast response of rotor speed. Unlike conventional designs, this method is capable of achieving the desired control performance. The closed-loop speed control in DTC for induction motors uses the PSO technique thus providing a practical level of accuracy. The results show good features and strong exemplary in dynamic system response and reduction in motor torque and transients.

In increasing the electrical power capacity of the Wind Power Plant (PLTB) there are several ways, among others, by increasing the number of generators, but the drawback is that the cost is too expensive because they have to build new plants. Another way is to increase the output power efficiency of existing wind power plants. One way is to use Maximum Power Point Tracking (MPPT) technology which functions to increase the output power of the power plant when there is a change in wind speed. In this paper, this technology is in charge of regulating the generator output voltage through a DC-DC converter type Cuk Converter, where the switching technique uses PWM (Pulse Width Modulation) by adjusting the amount of duty cycle. Changes in the value of the duty cycle depending on the size of the wind speed, so that to adjust the value of the duty cycle and speed up the switching response of the PWM control, a modern algorithm called the Fuzzy Logic Controller (FLC) is used. The results showed that FLC-based MPPT technology could increase the percentage of PLTB output power efficiency from 45.5% to 87%.

The problem that is often caused by the palm oil industry is the disposal of liquid waste which causes air pollution due to the pungent smell from the waste pool. If it is thrown into the river it will pollute the river and if it is thrown into the ground then the soil will be contaminated. Then an analytical study was conducted so that the liquid waste can be processed by analyzing methane gas whose raw material is liquid waste that is processed anaerobically to fuel the Biogas Power Plant. One of the large plantation potentials obtained from Palm Oil Mills (PKS), which processes Palm Oil Fresh Fruit Bunches (FFB) into Crude Palm Oil (CPO), is biomass waste with a fairly large amount in the form of organic waste in the form of empty coconut bunches. palm oil (Tankos), shells and coir, and liquid waste (Palm Oil Mill Effluent/POME). POME has high energy potential, but in general it has not been used optimally. POME is decomposed in sewage ponds left to decompose naturally. Converting POME into biogas to be burned can produce energy while reducing the impact of climate change. This gas appears as a result of the anaerobic breakdown of organic compounds. Organic liquid waste generated during palm oil production is a major energy source that has not been widely utilized in Indonesia. Converting POME into biogas to be burned can produce energy while reducing the impact of climate change.
