Abstract

ABSTRACT The utilization of cattle rumen contents, cattle manure, and banana peel waste to produce biogas through anaerobic fermentation is an alternative method to reduce waste in the agricultural and livestock sectors. This study was conducted to determine the quality of each composition, where the compositions in this research included a mixture of cattle rumen contents and cattle manure in 50:50 ratio, a mixture of cattle rumen contents and banana peel waste in 50:50 ratio, and a composition with three materials fermented simultaneously in a 40:30:30 ratio. The study used a biodigester with a batch operating system and single-stage configuration, with the fermentation process occurring in the digester for 17 days. The analysis aimed to assess the quality of biogas produced from each composition, measuring biogas volume and methane gas concentration for each trial. The results indicated that the highest biogas volume was obtained from the substrate composition of cattle rumen contents and banana peel waste (ratio of 50:50), amounting to 325.5 ml, while the highest methane (CH4) content was found in the composition of cattle rumen contents and cattle manure at 18.80% with a carbon dioxide percentage of 23.06%. The best flame test resulted from the experiment consisting of cattle rumen contents and cattle manure. Keywords: Biodigester, cattle manure, cattle rumen contents, banana waste, methane, biogas volume

Abstract

Horizontal axis wind turbines will generate voltage if the turbine rotates due to wind gusts. The bigger the wind blows, the faster the turbine spins and the greater the voltage generated. The braking system is needed for wind turbine protection when it receives very large wind speeds. This system is built using PID control based on microcontroller with reference to the output voltage. There are 2 units resistor designed as voltage sensors to the wind turbine output voltage. In testing, the wind turbine is rotated using artificial wind which is generated through a blower measuring 1.3 x 1.3 x 0.3 m, with a maximum wind speed is 11 m/s. The sistem uses PID kontrol which is used to brake wind turbine rotation and regulate its output voltage. Determination of constant parameters for proportional constant (Kp), integral constant (Ki), and Derivative constant (Kd) were obtained for Kp = 0.139, Ki = 0.715, and Kd = 0.006 respectively. The output voltage of the wind turbine can reach 60 volts and then controlled up to 24 volts according to the battery voltage requirements. In the test results, the control system managed to regulate the wind turbine voltage at 24 volts with a steady state error of 6.62%
