Engine knocking and misfire cause a negative effect on the engine power and the exhaust emissions such as HC, CO and NOx. They also cause permanent damages to the three way catalyst (TWC) system. And a heavy knock can cause severe damages to the engine itself, which gives more reason why it must be detected and corrected. This study introduces a new system concept for detecting combustion misfire and knocking using breakdown voltage (BDV) characteristics between spark plug electrodes. This system detects and evaluates the degree of combustion by measuring the breakdown voltage which predicts that the breakdown voltage depends on the pressure and the temperature.

In this paper, Mobile Agent (MA) and a number of intrusion detection system described. Considering the shortcoming of the current intrusion detection system, a new system called the intrusion detection system based on MA was described. Using the autonomy of MA, Intrusion Detection System based on MA avoids single-point failure, and robusts the system. As a result, the security of network has been increased.

Performa sepeda motor dipengaruhi oleh banyak faktor, diantaranya adalah penggantian beberapa part pada sepeda motor. Salah satu bagian yang banyak untuk dimodifikasi adalah busi yang dipercaya dapat meningkatkan performa. Bahan bakar yang digunakan juga dapat mempengaruhi performa. Tujuan dari penelitian ini adalah untuk melihat pengaruh penggunaan variasi busi terhadap torsi, daya dan emisi gas buang. Metode yang digunakan adalah menggunakan analisis uji statistik one way anova untuk dapat melihat pengaruh dari variasi busi yang dilakukan. Dari hasil perhitungan softwere analisis statistik one way anova dapat disimpulkan bahwa variasi busi tidak berpengaruh secara signifikan terhadap torsi karena F value < F crit (0,031 < 5,143253). Variasi busi tidak berpengaruh secara signifikan terhadap daya karena F value < F crit (0,003 < 5,143253). Variasi busi tidak berpengaruh secara signifikan terhadap HC karena F value < F crit (3,48 < 5,143253). Variasi busi tidak berpengaruh secara signifikan terhadap CO karena F value < F crit (4,97 < 5,143253). Variasi busi tidak berpengaruh secara signifikan terhadap , karena F value < F crit (1,207 < 5,143253). Variasi busi berpengaruh secara signifikan terhadap , karena F value > F crit (5,528 > 5,143253). Motorcycle performance is influenced by many factors, including the replacement of several parts on a motorcycle. One of the many parts to modify is the spark plug which is believed to improve performance. The fuel used can also affect performance. The purpose of this study was to see the effect of using variations of spark plugs on torque, power and exhaust emissions. The method used is to use one way ANOVA statistical test analysis to be able to see the effect of the variation of the spark plugs performed. From the results of software calculations one way ANOVA statistical analysis, it can be concluded that the variation of spark plugs does not significantly influence torque because F value < F crit (0.031 < 5.143253). The variation of the spark plugs did not significantly influence the power because the F value < F crit (0.003 < 5.143253). Variation of spark plugs did not significantly influence HC because F value < F crit (3.48 < 5.143253). Spark plug variation does not significantly influence CO because F value <  F crit (4.97 < 5.143253). Spark plug variation does not significantly influence , because F value <  F crit (1.207 < 5.143253). Spark plug variations significantly influence , because F value > F crit (5,528 > 5,143253).

Abstract In-cylinder pressure of an internal combustion engine is considered to be a major source of information about combustion process. It is a generally accepted method to obtain an in-cylinder pressure signal using a pressure sensor (transducer). A different method of approach is presented in this study. The information about the in-cylinder pressure can be obtained by measuring breakdown voltage across the spark-plug gap. The density of gas inside the combustion chamber effect on the breakdown voltage of the spark plug, which is derived by the application of a high bias voltage (30kV) to the sparkplug gap continuously. The correlation between maximum breakdown voltage position and peak pressure position is established by this principle. So it is possible to detect the peak pressure position by measuring the breakdown voltage of the spark plug. The analyzing method of the breakdown voltage signal is also presented.
