THE STUDY HOW TO ASSEMBLING SMD DEVICE INTEGRATED

Nowadays, the size of electronic components is not macro anymore, but already in micro size, even nano. In designing electronic device using surface mount device (SMD), a number of special components which has better characteristics is oftentimes required because of the demand which can not be tolerated. Hermetic SMD (airproof SMD) is a preference to fulfill the demand for design of small size, light weight, perfect thermal performance, free of switching waves, and also higher circuit efficiency.Keyword(s): assembling, SMD, thermal performance, effcient.Subject Description : B.7.Integrated Circuit | B.7.1.

THE SELLING SYSTEM OF PRODUCTION BY LOOKING CUSTOMER CHARACTER WITH DATA MINING METHODE (Case Study in PT Ultrajaya Milk Industry & Trading Company)

The advancement of computer technology influences many companies to use computer for data processing. Most of the activites in the company are product selling. Based-on the research at PT. Ultrajaya Milk Industry & Trading Company, their product selling activities are still using manual data processing and the computer usage within the company is not optimum yet. Thus, in this paper, system that can assist product selling activities, especially in providing information by making use of customer character, and swift report generator. The approach related to customer character employs data mining model, even though in this case, the existing database can not be categorized in the level of datawarehouse. Hence, modification of data mining approach has been done to match with the existing data.Keyword(s): Infomation system, Selling, Product.Subject Description : H.2. Database Management | H.2.8.

ENGINEERING ON-LINE LEARNING WITH CCTV LIVE-STREAMING WEB BASED OPEN SOURCE

Effectiveness media for learning activity is not enough only utilize the traditional media method, such as classical activity by using white board. Development of communication and computer technology can support long distance study by using network, server or web or by live interaction such as live streaming.Development of live-streaming in education activity is not only by using teleconference that need handshaking connection. Other model is by using web based CCTV live-streaming that use open source software. The web based model is more efficient then teleconference, the main reason does not need handshaking connection. The all web browser can be as client which can directly access multimedia document. Result of the research is an alternative learning on-line live-streaming model by utilize web server and open source.Key words: CCTV, learning activity, live-streaming, web.Subject Description : H.4.Information Systems Applications | H.4.3.

THE DESIGN, IMPLEMENTATION AND EVALUATION OF INFORMATION SYSTEM FOR ORACLE WORKFORCE DEVELOPMENT PROGRAM (OWDP) CLIENT USING OBJECT APPROACH

This research has purposes to developed OWDP information system based on web by using PHP as develop tool’s, to encourage the cource of ORACLE international certification by Gunadarma University until can be access by Internet, to reduce informations delay forparticipant candidates. For design used modelling language taht call UML (UnifedModelling Language). UML is architectur system that works in object oriented analysis design. In this research, using data from samplings that distributed to each participants in OWDP course.Keyword(s) : OWDP. ORACLE, UMLSubject Description: D.2.Software Enginee-ring | D.2.2.

STUDENT PERCEPTION ON BENEFIT AND SIMPLICITY VIRTUAL LABORATORY UTILIZATION OF OPERATIONAL RESEARCH

This research is intended to analyze the perception of the students towards the use of operations research virtual laboratory. Technology Acceptance Mode is used for the analysis of the process of information technology adoption. MPT comprises of three main variables, namely perceived usefulness, perceived easy of use and the actual intention to use. A sample size of 60 Gunadarma University students are taken, comprise of 30 students from the faculty of industrial technology and 30 students from the faculty of economics. The result revealed that the most of the respondents perceive that the operations research virtual laboratory can be used only as complementary of the face to face laboratory practice. The correlation matrix indicates high positive correlation between perceived usefulness and perceived easy of use. These two variables altogether demonstrate a highly positive correlation with the variable of the actual intention to use.Keywords : MPT, perceived usefulness, perceived easy of use, Operation Research V-LabSubject Description : G.3.Probability and Statistic | Correlation and regression analysis | ne

THE LATEST GEOGRAPHY INFORMATION SYSTEM (A REVIEW)

Geographic Information System (GIS) is a management tools in the form of information with the help of computers which related tightly to mapping system and analysis of any events taken place on earth. GIS is not only presenting data, but also merging the user interface, thematic information system and mapping system based-on structure and network of road traffic. Furthermore, it has the capability of analysis of specific geographic and information for a certain location. The existing problem with GIS is that the interoperabilty among applications and data. One of the solution is using Geographic Markup Language, proposed by W3C. In this paper, benefits, use, and recent approach to GIS will be explained.Keyword(s): GIS, Mapping, Location, Map.Subject Description : H.2.Database Management | H.2.8.Database Application | Spatial databases and GI

CONVERTING INFIX NOTATION TO POSTFIX NOTATION USING STACK APPLICATION IN DATA STRUCTURE

The use of stack becomes a common issue for memory address assignment, placement in data space, and other applications. As a part of data structure, stack application is also used for different needs, such as matching parentheses and conversion from Infix notation into Postfix. This paper was written to provide approach in the conversion process form Infix to Postfix in arithmetics.Keyword(s): Arithmetic, Infox notation, Postfix notation, Stack, Data structure.Subject Description : E.Data | E.1.Data Structures | Lists, stacks and quer

SPSS SOFTWARE AS A TOOL FOR ANALYZING RELATIONSHIPS BETWEEN LECTURE PERFORMANCE AND STUDENT SUCCESFULL (Case Study)

One of the key factor that influenced the fulfillment of resources is the performance of individual (employee) in an organization. For educational organization, human resources are related to educative workforce (lecturer) and non-educative workforce. One of the objectives of educational organization is the succesfulness of the teaching-learning process. SPSS, in this case, is used to facilitate analysis. The effectiveness of learning is indirectly influenced by the performance of lecturers. This research is conducted to find the relation between factors in lecturer performance and learning effectiveness as well as the strength of the relation. Indicator for learning effectiveness is measured by students marks. Factors in lecturer performance include motivation and competence in teaching, where motivation is measured from teaching method and attendance. Performance measurement of lecturers is assessed by the student using survey. Survey data are tested by using validity test and reliability test. Method of analysis used in this research is statistical correlation techniques with non parametric method using Spearman rank correlation. The results show that there is a small and positive correlation between lecturer’s performance and learning effectiveness. Possitive relation with small value shows that, indirectly, the higher the lecturer’s performance the better the student’s succesfulness and, conversly, the lower the lecturer’s performance the worse the student’s succesfulness in learning process.Kata Kunci : keberhasilan belajar, kinerja dosen, korelasi SPSSSubject Description : K.3.Computeres and Education | K.3.1.Computer Uses in Education | Collaborative Learnin
