Abstract

The aim of this research is to find the influence of ignition timing to emission of 4 stroke motorcycle. The emission is affected by several things such as octane number, combustion process, air consumed. Emission will affect to the green house gas and finally will produce global warming. In addition, the available of fuel will decrease year after year so we must use it effectively. To know the influence of ignition timing to emission, then, this research was done by experimental method to find data. The timing ignition was chosen in 10o, 15oand 20o. For each timing ignition the engine would be rotated from 3000 rpm to 6000 rpm, then the data of emission would be measured by measurement apparatus. From this research, it could be found that ignition timing in 10o had combustion process better relatively than others. It was proven by emission produced by this timing ignition’s combustion process.

Abstract

Stratigraphic analizes for samples from the Sentolo Formation is marl and carbo-naceous sandstone on Gunung Gede and Gunung Kinjeng, were examined for foramini-feral occurence. About fourty eight species of microplanktonic and twenty seven species of microbenthonic were identified. They have been studied previously in this three family Globigerinidae, Globorotalidae, Hantkenidae. This family clasificasied from one super fa-mily Globigerinacea. The analizes species of microplanktonic fosils have been correlated with N-9 Gunung Gede samples, and Gunung Kinjeng samples N12-N14 (Middle Mio-sen). The microbenthonic fosils have been identified that which depositional environment of the Sentolo Formation was Upper Bathyal.

Abstract

The mixture of etanol and gasoline which is called bioetanol could be an alternatif for fuel. An etanol could be made of cassava. This article discusses a further development of ethanol production and its blend with gasoline and its characterization as a fuel. The experimental work was devided into three steps, i.e. material preparation, fermentation, and finally distillation at 80, 95 and 110 0C. The destillitation resulted a 95% ethanol and the conversion of carbohydrate to ethanol was about 93- 98%. The analysis results of the blend of gasoline and ethanol such as kynematic viscosity 100 oF at temperatures of 40 and 60 oC was 8,645 cSt dan 8,151 cSt respectively and the specific grafity at temperatures of 40 and 60 oC 0,7472 dan 0,743 respectively. The flame test of the blending of gasoline: ethanol volume of 9:1 and the 100 % gasoline results showed that the flame of bioethanol (9 :1) was about 39-40 second which was 4-6 second longer than the 100 % gasoline that the flame was about 34-35 second.

Abstract

Technometric is one of technology component contribution measurement method that consists of technoware, humanware, inforware and orgaware technology (ES-CAFE). The usage of AHP (Analytic Hierarchy Proces) method has weaknesses in measuring the assumption of cluster criteria independency and other decision elements. This research analyzed the possibility of ANP (Analytic Network Process) implementation in technometric method for handling dependency relation among the technology components. ANP Method is AHP development method using feedback approach and decision components that are arranged in network shape not in linear hierarchy, so it is able to count interdependency relation between the technology component and elements in industrial system more completely. For testing the validation of a ceramic industrial object that will be used as an object of technology intensity measurement. The research result shows that measured technology component or almost all of the elements inside make multi direction relation, means there is an interdependency relation between the component and the elements. This technology coefficient contribution for industry is 0.81, with technoware component contribution 0.86, humanware 0.88, orgaware 0.8, and inforware 0.69.

Abstract

This manuscript presents the experimental results of leakage current waveform properties which produced on the new-clean porcelain and epoxy resin insulators due to various voltage, temperature, humidity and pressure parameters. The measurements have been done in the hermetically sealed chamber where the parameters could be regulated and monitored or recorded simultaneously. The examined leakage current parameters were wave amplitude, phase angle or power factor, first to thirteenth odd harmonics and THD. The analysis was done with some multivariate statistical tools, such as correlation matrix, pca and scree plot. The results indicated that leakage current amplitude and phase angle were influenced by humidity, indicated by correlation coefficients as 0.56 and -0.88 respectively on new-clean porcelain insulator. Otherwise, on the new-clean epoxy resin insulator, leakage current magnitude influenced to the phase angle as -0.75. These were supported by principal component analysis. Based on the scree plots, the extracted of information quality were higher than 80%.
