Modeling wind speed variations is a very important requirement in determining energy potential to find out typical winds speed in an area. Data obtained from the average wind speed in Banda Aceh City of Aceh Province were correlated from NASA Data Access (Prediction of Worldwide Energy Resource) for 1 (one) year. Wind speed data is analyzed statistically to determine the potential of wind energy as a small scale power plant, which is grouped on an annual basis. Wind power distribution is obtained by the Rayleigh distribution function method, with the aim of predicting wind energy produced as a wealth study for designing small-scale wind turbine power plants. The calculation results show that by using the annual clustering Rayleigh function method, cumulative distribution and probability density functions will be obtained. The available power from the winds of the Banda Aceh region for 1.4 m2 turbines sweapt area with an average wind speed of 4.4 m/s produces an energy potential of around 237.9 kW-hrs per year. The Rayleigh function of this distribution uses estimated parameters, which are expected to provide a more accurate prediction of the average energy produced for a region. The annual variations in wind speed and power density functions described in this article are very useful to ensure that the generator is selected and determined appropriately, so that an optimal wind turbine power plant will be obtained.

Solar modules have current and voltage characteristics that are non-linear, so efforts must always be made to work at the maximum power point so that no energy is wasted. The characteristics of the solar module will change depending on the level of radiation and temperature which causes the output power of the solar module to fluctuate and become unstable. To reduce oscillations in the output power of the solar module, the Fuzzy Logic Control (FLC) method used using the boost converter. Several studies have been done to maximize the output power of solar panels, one of which is by using namely by using Maximum Power Point Tracking (MPPT). This study aims to obtain the maximum power point in a set of solar modules arranged in series and parallel through the performance of the FLC method. In tracking the maximum power point during normal operation, the fuzzy method works together with a boost converter. Fuzzy-based MPPT was tested on a solar module under several radiation and temperature conditions using Matlab / Simulink software. The Fuzzy design method shows better results compared to other methods. The results obtained show the advantages of the FLC method in terms settling time, power loss, and oscillation at the point of the operating system.

Panas matahari yang diserap oleh modul surya dapat menaikkan suhu modul surya dan menurunkan tegangan keluarannya. Oleh karena itu perlu usaha untuk menurunkan suhu modul surya agar kinerja modul surya agar tetap optimal. Pemasangan bahan heatsink digunakan untuk mendinginkan modul surya. Pemakaian heatsink mampu menurunkan suhu modul surya sebesar 45,9oC lebih besar daripada tanpa menggunakan heatsink 53,3oC sedangkan tegangan keluaran dari modul surya mampu ditingkatkan menjadi 20,03 volt. Dari hasil penelitian dapat disimpulkan bahwa pemakaian bahan heatsink lebih baik untuk menurunkan suhu modul surya daripada tanpa menggunakan heatsink.
