Abstract

The potential raw materials for biogas formation through anaerobic treatments available on the campus of Andalas University (Unand) in Padang are the cafeteria’s food waste and cow feces. This study was aimed to look at the effect of cow feces in the formation of biogas from food waste that used a floating drum digester which was conditioned twice. Retention time was 20 days and the pH of packing material was conditioned by adding limestone. The ratio variation of packing materials composition such as food waste and cow feces were 100:0 (control digester), 75:25 (test 1 digester with a C/N ratio 30) and 50:50 (test 2 digester with a C/N ratio 25). The results showed that cumulative volume of biogas in control digester was 0.927 liters with methane gas estimated 591.885 mg/L and did not light when burned. The cumulative volume of biogas in test 1 digester was 13.715 liters with methane gas estimated was 15502.61 mg/L with the reddish color of blue flame. The cumulative volume of biogas in test 2 digester was 10.18 liters with concentration of methane gas was estimated 23297.59 mg/L and with blue color flame.ABSTRAKBahan baku potensial pembentukan biogas melalui pengolahan anaerobik yang tersedia di Kampus Universitas Andalas (Unand) Padang yakni sampah makanan kantin dan feses sapi.

Abstract

The biggest energy source used today is still predominantly derived from fossil fuels, which is known fossil energy resources are non-renewable so that over time will run out. Therefore, the nowadays conditions should utilize energy sources that are renewable. One of the renewable energy sources that are environmentally friendly and are easy to come is wind energy, which its utilization uses wind turbines. Wind turbines can be used for generating electricity so that it can overcome one of the problems of energy for the fishermen in Padang. Padang has a low to medium wind speeds, so that the suitable wind turbine is Savonius turbine type. The research was done by creating a model of Vertical Axis Wind Turbines (TASV) Savonius type with 2 stages of blades made of aluminum material.  Each rotor is having 50 cm diameter and 80 cm height. Parameter studies that measured are wind speed, rotor rotational speed, turbine force, voltage and current in the generator. Meanwhile, the observation is held on Air Tawar Padang, West Sumatra. From the performance of the Savonius wind turbine in this research is got  5.9 m/s maximum wind speed, 225,8 rpm maximum turbine rotation, 4.7%  the highest Cp and 2 watts the highest power and can catch 160.2 watts the wind power.
