Wind energy is a resource that is abundant, environmentally friendly, and renewable, therefore it has the potential to be developed. Savonius vertical axis type is suitable for application in low wind speed conditions. The Savonius wind turbine has good self-starting so that it is able to rotate the rotor even though the wind speed is low, besides that the torque it produces is relatively high. This study aims to determine how differences in OR affect the performance of Savonius turbines with an aspect ratio (AR) of 2. The experimental method was applied in this research to investigate the characteristic Cp of the model using the wind tunnel with different overlap ratios of 0.1, 0.15, 0.2, 0.25, and 0.3. The wind turbine model that has been made using a 3D printing process made of PLA + material. The results obtained in each OR test are the maximum Cp value for the variation OR 0.1, which is 0.121, OR 0.15, the maximum Cp value obtained is 0.213, OR 0.2, the maximum Cp value is 0.245, OR 0.25, the maximum Cp value is 0.224 and OR 0.3, the maximum Cp value is 0.210. Based on the five overlap variations, the maximum Cp ratio is obtained at OR = 0.2, namely Cp = 0.245 and TSR = 0.7. The OR value of 0.2 is able to maximize turbine power and minimize negative torque because the flow through the overlap area can maximally direct wind power to the maximum backward blade.

A stove is a tool used by the community to cook. The fuel used by the stove is LPG gas or kerosene, LPG gas. The scarcity of kerosene has occurred starting from a few years ago. At that time to get kerosene the people had to pay very expensive and even had to be willing to do a very long queue to get a few liters of kerosene. To anticipate this, we should think of alternative energy as a substitute for kerosene. This activity aims to provide a solution in overcoming the problem of pollution of rice husk waste as an environmentally friendly alternative energy through the manufacture of husk stoves to save fuel oil and gas KKN activities are held on 28 June to 8 August until September 2018. Number of students involved is 24 people. The form of activities carried out in the form of counseling, demonstration and training in making husk stoves by utilizing rice husks was carried out by Unand lecturers and KKN PPM Unand students by involving the community in Nagari Kinali Pasaman Barat. From this activity, the community was very enthusiastic and able to make husk stoves and process rice husk waste into the fuel of the husk stove. Besides that, husk stoves can be used by the community to cook in overcoming scarcity of kerosene as well as the utilization of rice husk waste as fuel. The stove is designed to burn rice husks using a limited amount of air for combustion which produces a blue luminous fire, which is almost similar to an LPG stove. From this activity, it is expected that the community can optimize the use of husk stoves in their daily lives to save costs and overcome the scarcity and high cost of LPG and kerosene as well as overcome environmental pollution from husk waste.
