<![CDATA[The Walet bird`s nests are believed to have some healing power for a number of diseases. Therefore, they are highly valued commercially, so that the drive to collect them are very strong from hazardous places such as caves,cliffs, steep shoves, dense forests, etc. Efforts to give artificial homes for the Walet birds are promising for business, espe-cially for the much lower workers safety risks and more stable best`s quantity produced. Some challenges have to be able to overcome resorting to the regulating power of a mi-crocontroller. First of all, to atract the birds, the design of would be home should be stu-died thoroughly, including its location away from the disturbing human activities. Second, the right indoor atmosphere condition should be guaranteed. A set of hardware can be developed to provide a monitoring system on the temperature, humidity as well as the illumination level of the room dedicated for the Walet. To maintain the right temperature and humidity, an automatic water sprayer unit is added during the dry days of the year. A programmable Walet sound reproducing equipment is vital to safe the farmer`s time to operate it manually.]]>

<![CDATA[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.]]>

<![CDATA[Analysis performed on web server logs have traditionally been widely used to see the web visitor activities such as determining the amount of access to web pages, anyone accessing the web user and the time to visit the web and visited URLs and more statistical analysis. But it is still very little information about the relationship between exis-ting data on the web, the sequence of requests made by a user or group of users who have access to a web site. To overcome these problems required a web mining tech-niques. Web mining is a technique to automatically discover and extract information on the web. This study used different techniques to sequential pattern Apriori algorithm to identify patterns of web site navigation. The the applications that have been made will show recapitulation of information about the number of visits per day, a search of browser used, details of visits that include IP addresses, proxy server, the location of the sequen-ce pattern visitor and web traffic. Web navigation patterns using Apriori is able to produce the sequence pattern of answering pages accessed by visitors. This pattern always varies depending on the minimum support are included. The higher MinSup, so little sequence variation pattern of visits and reverse the lower the value of the Minsup more and more variations of the sequence pattern of visits by users.]]>

<![CDATA[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.]]>
