The method used to predict student achievement is the algorithm C4.5 decision tree method using several criteria based on the educational background of students before, they are the uan mathematical value, the uan Indonesian value, the uan English value, the majors in the school, and the average report cards in the school of origin. This system will be made based on the web to be more effective, fast and easy to use. This system will produce predictions of student achievement information on Informatics Engineering. © 2016 Institute of Advanced Engineering and Science. All rights reserved.

The paper attempts at reviewing a previous research entitled “Hybrid GR-SVM for prediction of surface roughness in abrasive water jet (AWJ) machining” and some problems were found in its reducing parameters process and prediction model. The authors presented a hybrid of grey relation analysis (GRA) and support vector machine (SVM) to estimate the roughness surface in a certain dataset of AWJ machining. Their proposed method may not work in real case of AWJ machining as it is claimed. This paper gives a counter model in order to illustrate these remarks. © 2016 Springer Science+Business Media Dordrecht

Debonding or decohesion along a fiber-matrix interface frequently becomes the main mode of failure of a composite structure. Hence, a methodology to evaluate the decohesion is of interest of many scientists and engineers. Unfortunately, many existing methods such as the micro-bond method, the fiber pull-out method, and the fiber push-out method are too restrictive in term of the specimen design and the rate of loading. In this work, we propose a methodology to characterize the decohesion at various loading rates and verify the method experimentally. © Owned by the authors, published by EDP Sciences, 2014.

These days people demand more from design for a valuable offer, a design that could understand them more. And this sort of things happen in fashion design too, people need more than just a fancy and extravagant clothes and it becomes a new challenge for fashion designer to explore the design and combine it with the need of the future market. The idea on focusing on function as added value in fashion design has already emerged since the early Modernism in the early 60's. In Modernism, the beauty of aesthetic formulated based on function and material/structure exploration considered to be the future of effective design. But as time goes by, Modernism was considered to be rigid, dull and cliché, their beauty esthetic regarded as inhuman and less personal. The market demand seemed to be shifted to something more personal and have a “soul” in design, which later answered by Post Modernism that bloom in late 70's until today. So the question of how Modernism approached design, which in the beginning was actually based on human needs, technology, effectiveness and function to offer, have failed the market? How Postmodern with personal touch that less effective can answer the need of soul for humanist design in the future? But in the end are both Modernism and Post Modernism really an opposite?. © 2015 American Scientific Publishers. All rights reserved.

This study is conducted to investigate the relationship between price fairness, customer satisfaction, loyalty, and price acceptance in Indonesia's low-cost carrier market. The study is using a combined method of a quantitative study with paper-based questionnaires and a qualitative study by means of a focus group discussion, to LCC customers in Jakarta. Convenience sampling collects 200 usable respondents. The data is analyzed using the regression method in SPSS. The empirical result shows that in the low cost carrier market, price fairness has an impact on customer satisfaction, loyalty, and price acceptance. Customer satisfaction affects price acceptance and loyalty positively. However, loyalty has shown no effect on price acceptance. This study suggests that customer satisfaction is the main factor to build price acceptance in the low-cost airlines industry. Some managerial implications relevant to the findings are provided. © 2015 American Scientific Publishers. All rights reserved.

The retail fashion industry is growing rapidly in Indonesia, currently dominated by international fashion brands, followed by local designers and local fashion brands. There is very tight competition in the industry. Indonesian’s local brands have to create collections with good brand images to be able to compete and attract Indonesian consumers. The consumers appreciate local products, which have good quality design, styles, fabrics and competitive prices with positive brand images that make them feel confident wearing them. To be able to compete with the international fashion brands, it is very important for a local fashion brand to fulfill those expectations. This paper was conducted by choosing one of the middle class local fashion brands in Jakarta, called Mint. Mint products have been sold in Indonesia since 2002, from 15 boutiques and more than 200 locations such as department stores. In 2007, Mint got a recognition certificate from Business Indonesia magazine as an ‘Indonesian Original Product’ (Produk Asli Indonesia 2007). Mint targets professional, urbane women between 20 and 35 years old. This paper is to determine factors of the decision of Mint’s customers in choosing the fashion brand, and if brand image as a local brand will influence the buying decision. This paper uses questionnaires, interviews, and observations as its research methodology. The results show that the factors influencing buying decisions for Mint are: good quality of products in many varieties; affordable price; and attractive designs. Brand image as a local brand is accepted in the consumer’s mind as long as the product fulfills their needs in quality. It is recommended for Mint to do regular research into buying factors since fashion keeps changing, and to maintain a good brand image as a local brand. Findings are also applicable for new fashion brands, created by entrepreneurs before they start their businesses in fashion retail in Indonesia. © 2015 American Scientific Publishers.

Understanding the behavior of tourists has been an important topic of research for decades in tourism studies. A systematic study on the behavior of tourists visit to Indonesia, specifically the reason choosing this destination for vacation and also type of participated activities seek by different tourist groups, is lacking. Therefore, this study is undertaken to fill the gap by profiling the tourists and associating them with different tourism activities. A self-administrated questionnaire was distributed to tourists in Jakarta International airport and some tourist areas around Jakarta. Statistical analysis such as factor analysis, multiple linear regressions and descriptive analysis were employed in order to analyze the data. Results indicated the push factors behind choosing Indonesia for vacation and also different participated activities among tourists from different geographical origins. The findings of this study should be considered by tourism marketers and stakeholders while developing marketing strategies. Results also will have significant practical applications and theoretical implications. © 2015, ASERS Publishing House. All right reserved.

Inverse Problems in Science and Engineering | Year: 2015

There are cases in engineering applications where the involved impact forces are impractical or difficult to be directly measured. In such cases, the impact forces may inversely be reconstructed on the basis of the associated-induced elastic responses. However, the inverse impact force reconstruction is an ill-posed problem. So far, various methods have been proposed. Many require complex mathematical treatments; thus, they are impractical for experimental engineers. In this article, we adopt the Wiener filter method and introduce a regularization technique so that the method can provide an optimum solution which balances the aspects of the minimum noise and the minimum residual. The proposed method is evaluated using three examples of the impact problems. The evaluation reveals that the regularized Wiener filter method is less sensitive to the regularization parameter unlike many of the existing methods. Therefore, the method is more suitable for practical applications. © 2015 Taylor & Francis

This paper presents the modeling and simulation of offshore wind power platform for oil and gas companies. Wind energy has become the fastest growing renewable energy in the world and major gains in terms of energy generation are achievable when turbines are moved offshore. The objective of this project is to propose new design of an offshore wind power platform. Offshore wind turbine (OWT) is composed of three main structures comprising the rotor/blades, the tower nacelle, and the supporting structure. The modeling analysis was focused on the nacelle and supporting structure. The completed final design was analyzed using finite element modeling tool ANSYS to obtain the structure's response towards loading conditions and to ensure it complies with guidelines laid out by classification authority Det Norske Veritas. As a result, a new model of the offshore wind power platform for 5 MW Baseline NREL turbine was proposed. © 2015 Taufik Roni Sahroni.

Residents’ perception of tourism development has received increasing interest from tourism industry managers. Although the number of tourists visiting Indonesia is increasing, the fact about educational tourism and its effect on residents’ perception has not been explored. The objective of this study is to understand the implication of educational tourism in relation to local residents. A qualitative approach was conducted with some local residents. The study revealed those local residents’ both negative and positive aspects of educational tourism. In practice, this research will have benefit for the Indonesian government, the host university and for the local residents in the area. © 2010 – 2017.
