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

This research reviewed the effect of induction voltage resulting of the electromagnetic induction from the thunderbolt attack to the electronic equipment especially if the induction effect to the component has a high sensitivity rate that was IC CMOS component. In this study the experiments done in the laboratory of High Voltage Technique where the impulse voltage as a simulation to the thunderbolt external voltage surge for the Electronic circuit. Experiment I the distance component of the test article to the test point was 5 cm with the impulse voltage of 99.3 kV, induction voltage 158.41 V, Experiment II with the distance of 7.5 cm, the impulse voltage 88.3 kV so the induction voltage 105.62 V IC, in the experiment III the distance of the test article was 10 cm from the test point. The impulse voltage 88.3 kV and the induction voltage was 79.2 V, In the experiment IV the component distance was 15 cm. the impulse voltage 88.3 kV and the induction voltage as big as 52.74 V.From each experiment IC make damage, where distance component from each experiment settled more distant so component no make damage. From the measurement and calculation yields then the induction voltage resulted will damage the IC component conformed to the yield presented by Hasse in the table 2.1 where the component CMOS 70-100V. Where the study results proved that the electromagnetic induction from indirect thunderbolt attach can result an interference and damage to the electronic component tested, as the distance between the component and the ball gap to the impulse tension was very influential in determining of damaged mechanism of IC in self.
