<![CDATA[The Ignition on a motorcycle is an electrical system that produces sparks in the combustion chamber. If there is a mass of ferromagnetic material moving closer to the sensor, then the pulser will generate an electric current. Greater the electric current it generates. With the working principle of such a pulser, it can be used as a rotation sensor and sent to the ignition coil to produce a higher voltage which will produce sparks at the end of the spark plug electrode. The perfection of the system affects the motor work system. A good CDI condition will make it easier to increase the RPM (Rotations Per Minute) and when the spark plugs are in good condition, the motorbike's performance is getting optimal. There can be a useful tool for analyzing the damage to the CDI and the spark on the spark plug by integrating the electronic system in the motor ignition system. An electronic circuit that connects the motorcycle's ignition system through the output of the pulser circuit signal, which triggers the CDI input instead of the pulse magnet. Because the CDI and motor spark plugs are one of the main components that play an important role in the performance of the combustion motor. So that the electrical system can work without using mechanics and can be used as a tool to be able to analyze CDI damage and motor spark plug performance because CDI and spark plugs are some of the main components that play an important role in combustion motor performance. The result is that the tool can test CDI and motor spark plugs efficiently after which it can conclude the damage and can distinguish the characteristics of the CDI and the motor plugs.]]>

<![CDATA[Epileps is a disorder of the contents of the nervous system of the human brain resulting in the presence of abnormal activity that is the excessive activity of neuron cells in the brain. In Indonesia there are more than 1,400,000 cases of Epilepsy each year with 70,000 additional cases each year. About 4050% occurs in children. A widely used method for assessing brain activity is through a sephalogram (EEG) Electrone signal. The Epilepsy classification system is built with extraction and identifikas stages. Wavelet exctraction is suitable for non-stationary signal analysis such as EEG signals. Wavelet tranformation can extract signal components only at the required frequency. So that it can also reduce the amount of data but without losing meaningful information. But to make it work and can be used on a system needs to be done classification in order to be able to distinguish between commands from each other. So it is used K-Nearest Neighbour (K-NN) classification method so that the signal that has been eliminated buzz can be directly entered into the classification to determine the correct wrongness of a data. In this study obtained the results of data accuracy value that K = 1 has the largest percent of 100% and the smallest percent is found in K = 7 and K = 11 namely 14.2% and 18.2% it is caused by the presence of classes that do not match the test data so as to reduce the percentage of accuracy in the K.]]>

<![CDATA[In the cultivation of rice, there is never a problem with the name pests. If not controlled, the pest attack will affect the productivity level of the plant. Pests that attack rice plants include leafhoppers and birds. Birds have a very large percentage rate in attacking rice plants, namely the bondol bird which is one of the grain-eating birds. This bird is a very troubling pest for rice farmers because it causes crop yields to drop dramatically. There are several ways to repel birds, usually farmers using the manual method by making a rice field and crackle which is then tied to a rope. When using this method, farmers have to wait for agricultural land for approximately one month. This is considered inefficient considering the farmer's job is not only to wait for the rice plant until harvesting. So that in this study, a tool that will be used to repel bird pests will be designed by using solar panels as a source of voltage with sound output using a frequency of 1.5 - 3 KHz.]]>

<![CDATA[Solar energy can be used by buildings. Parts of the building can convert solar thermal energy into electrical energy.The roof and walls are the parts of the building that receive the most sunlight. Therefore, the roof and walls of the building can supply electricity with the thermoelectric generator. The aim of this research is to get the maximum possible output power from the thermoelectric generator system. From the output power produced, it will be possible to find the feasibility of a thermoelectric generator to be used as an energy source for the roof and walls of the building model. The building model is designed simply where the roof and walls can be located a thermoelectric generator system, which consists of a heat sink, a thermoelectric circuit and a cooling system. The heat sink used is aluminum. The thermoelectric circuit consists of 15 sets which are assembled in a series connection arrangement. The cooling system used is active cooling, where water as the cooling fluid circulates continuously during the operation of the system. The thermoelectric hot side temperature is obtained from solar thermal radiation through a heat sink. Meanwhile, the temperature on the cold side of the thermoelectric is the result of the effect of the cooling system that is attached. The temperature difference between the hot and cold sides of the thermoelectric produces a system output in the form of electric voltage and electric current. This study obtain that the generator system on the roof with a temperature difference of 8.90 oC on the hot-cold side produces a power of 1.953 watts. While the generator system on the wall with a temperature difference between the hot-cold side of 1.80 oC produces a power of 0.030 watts.]]>
