Abstract

The production of one ton of rice straw will produce 250 kg of dry hay (Isni, 2011). A sizeable amount, straw as one of the ingredients that are very effectively used as raw material for biogas. Straw into biogas conversion value reaches 250-350 liter / kg dry weight (Arati, 2009). For a perfect straw metabolism, staw should be cut first. Enumeration is done manually is less efficient because the enumeration is done by using a knife to cut hay will produce a piece of straw that are not uniform. Good hay cutting measure is about 2-5 cm. If the straw enumeration is done by machine, then it takes the feeder to the cutting machine tool that can feed the straw so that the resulting size of 2-5 cm. To make the necessary feeder, conveyor, DC motors, magnetic clutch and infrared sensors. Conveyor serves as a carrier of straw, DC motors as actuators, magnetic clutch as conveyor control and infrared sensor as a measure of pieces of straw. After testing, show that it works and works well.

Abstract

The creation of an intelligent biogas reactor made from rice straw is a long-term goal of this research. Biogas reactor is a breeding ground for methanogenesis bacteria in the process of methane gas formation (biogas) which can be used as fuel. The proliferation of these methanogenesis bacteria depends on the temperature, degree of acidity, humidity and volume of raw materials contained in the biogas reactor, if these parameters are out of threshold then the result of methane gas will be reduced or even the methanogenesis bacteria will die will lead to cessation of methane gas production. Increase the biogas gas pressure to be used as fuel of the test object in this case the petromak lamp.
