Abstract

Visual modeling softwares are numerously available based on both open source and proprietary. However, the softwares are not easy to use and tools available are so confusing for users. Therefore, the evaluation model is needed to choose the proper software. The purpose of this study is to create a model to evaluate the visual modeling software from the user interface and usability. Studied softwares are open source-based because they can be obtained easily for free. The softwares are Umleditor, Umlpad, Violet UML editor, ArgoUML, HE, StarUML, UMLet, Winbrello. This evaluation model is also able to evaluate other softwares. This evaluation uses DECIDE framework which is a guiding framework for evaluation. Evaluation approaches and techniques used are GOMS approach. The final results of this study is an evaluation model that provides software recommendations, namely UMLet 9.1 as well as one which has good usability, like effectiveness, safety, good utility, learnability, memorability, although for efficiency it gets the second place compared to DIA.

Abstract

Running the business process of labor supply is not easy since it involves several parties, and n supported by elements of the documents obtained from internal and external parties. PT XYZ as a company dealing with labor supply service to foreign countries has not had any competent information systems in supporting its business processes. Therefore, this research is expected to produce a draft of information system and database applications that can support the administrative activities of labor supply of the company. The research used both analysis and design methods. Analytical method includes survey of the current system done by observation, interviews, identification of the information needs of the survey results and identification of system requirements. The design method consists of designing a model system using UML notation, designing databases and user interfaces for supporting applications. The information system applications resulted in this research can be a competitive advantage in marketing their employment services and improve business processes of PT XYZ.

Abstract

The objective of this research is to develop a web-based-online-stock-simulation application applying Virtual Private Network (VPN) technology. The web-based application is prefered for user’s convenience and comfort since it does not require any software to be installed on the client side and is also accessable anywhere and anytime with internet connection availability. The application is developed by means of analysis and design towards the technology needed to establish the connectivity between servers through internet as well as database analysis and design. The data are real time derived from the Indonesia Stock Exchange (IDX) and forwarded through an official data vendor PT XYZ. Data from the IDX will be captured by a middleware application at PT XYZ and forwarded to www.kontan.co.id. This application has been tested and succesfully run by around 700 users. This tool is expected to provide a kind of education and motivation to beginner-level investors who want to be engaged with the stock-trading activities.

Abstract

Executive information system (EIS) has been widely used in enterprises and institutions to help the executives make decisions quickly and accurately for the organization's business needs. A research is conducted to create a marketing executive information system that can produce analytic reports and comparison reports for the executive of Benza Prima. For information search the fact finding techniques is utilized by conducting surveys directly to the company to study the company needs and the running procedures. The executive information system design uses Object Oriented Analysis and Design (OOAD) methodology. The research results in an executive information system that produces report in forms of pivot tables and charts to help the Benza Prima executives make decisions. The marketing executive information system design is expected to provide analytic information that can be used by the Benza Prima executive as an analytic tool in planning marketing strategies.

Abstract

Concerning the several pest attacks in Karawang, Cirebon, and Cianjur districts a mobile computing-based information system is built to accelerate the data flow and early warning information to the person in charge at Ministry of Agriculture. Based on interviews and surveys to the locations planted with rice, corn and soybeans some data of the breadth and intensity of pest attack is obtained, used as the basis design for the early warning data structure. The information systems development method refers to the systems development life cycle (SDLC): identification of needs data and information, analysis and system design, testing, implementation and evaluation system. The result is a mobile computing-based information system of pest control and crop disease early warning that can accelerate data and information transmission that the stakeholders in the Ministry of Agriculture can make decisions quickly and correctly.

Abstract

Konsep customer relationship telah berubah menjadi customer engagement, yang kini dikenal sebagai konsep Customer Relationship Management (CRM). Karakteristik CRM mengakomodir tiga hal: pemasaran, penjualan, dan layanan. Industri pendidikan memiliki karakteristik paling kuat pada layanan karena keterikatan pelanggan untuk waktu yang cukup lama pada institusi pendidikan. Kepuasan pelanggan akan memberikan rekomendasi positif kepada keluarga dan kerabatnya. Sebaliknya ketidakpuasan pelanggan akan membawa rekomendasi kurang baik. Dengan demikan, pelayanan pelanggan selama masih terikat dengan perusahaan sangat menentukan keberlangsungan bisnis perusahaan selanjutnya. Penelitian dilakukan menggunakan model EUCS (End User Computing System) dimana hipotesisnya diuji berdasarkan análisis korelasi dan análisis regresi serta menggunakan IPA (Importance Performance Analysis) untuk melihat hal-hal yang perlu ditingkatkan dengan menghitung gap analisisnya. Berdasarkan análisis korelasi, semua hipotesis H1 (ada hubungan) diterima dan berdasarkan análisis regresi, semua hipotesis H1 (berpengaruh) diterima. Dan berdasarkan IPA, tiga dari lima variabel perlu peningkatan sebagai prioritas pertama. Sementara untuk prioritas kedua semua variabel perlu ditingkatkan.

Abstract

Slope – deflection equation method is an analysis method to solve statically indeterminate structure. This method is a simple technique to analyze continuous beam, either prismatic or non prismatic. The technique for analyzing non prismatic beam is based on the prismatic beam concept, but with the introduce of some modification coefficient. These coefficients are available in some textbook discussing about structural analysis. This research has an objective to compare the analysis result of a continuous non prismatic beam, with slope – deflection equation method, and result from a structural analysis program (i.e. SAP 2000 v.11.00). The internal moment at the joints produced from this two method will be compared each other. The results show that there is a small difference resulted in internal moment, obtained from hand calculation with slope – deflection method and from software output. The differences resulted from this two techniques are 2 up to 6%. Based on this result it can be stated that slope-deflection method can be used to analyze statically indeterminate nonprismatic beam with some modification factors. The result obtained is nearly the same with one obtained from commercial softwares.

Abstract

Ground measurement helps illustrate a situation of land map to ease a civil engineer determining the center point of a building. From the situation map can determined the further works such as determining the point of building, land leveling, determining the point of the foundation and the volume of work for hoarding the land. A tool used for measurement activities is theodolite. Theodolite serves as a tool to determine the angle formed between the two points at the time of measurement. Drawing a situation map requires the results of the point measurement data. Theodolite is divided into two types, digital and manual. This study compares measurements results using both digital and manual theodolite performed at Kijang Campus, Binus University. From the comparison of data processing generated large differences in the coordinate system on the situation map with ranging from 1.31% to 322.67% on the abscissa axis and 0.39% to 41.83% on the ordinate axis.
