Abstract

This study aims to test the hypothetical model that describes the correlation between motorcycling behavior and four latent variables assumed to make up bikers in action. A survey of 350 motorcyclists through purposive sampling was done by employing a research instrument. Validity and reliability test of research instrument were conducted by calculating the Cronbachs Alpha. Whereas, the hypothesis model test was conducted using statistical technique of Structural Equation Modeling (SEM) through Lisrel 8.72 software. CFI, Chi-square, and RMSEA are fit indexes used to test the suitability of the hypothesis model with field data (model fit). Structural Equation Modeling (SEM) and Confirmatory Factor Analysis (CFA) were used to evaluate the reliability and structural validity of the instrument used. Besides, they were used to test the hypothesis that a positive relationship between the observed variables and the four latent variables, as well as a positive relationship between the four latent variables and motorcycling behavior construct.

Abstract

This research aimed to investigate the importance of take-out food packaging attributes, using conjoint analysis approach among consumers of take-out food products in Jakarta, Indonesia. The conjoint results indicated that perception about packaging materials (such as paper, plastic, and polystyrene foam) took the most important role in overall consumer perception. The clustering results showed that there were strong segmentations for take-out food packaging material considered most important by consumers. Some consumers were mostly oriented to the colour of packaging, while some concerned on packaging shape and packaging information. Segmentation variables based on packaging response could provide very useful information to maximize image of products through the package’s impact

Abstract

Global trade and the abolition of trade barriers lead to the proliferation of imported food products such as various types of fast food products (RTE: ready-to-eat food) sold by convenience stores mainly scattered in Jakarta. The question is what causes consumers choose certain convenience store to buy RTE Product and not choose another outlet category. To understand consumer perceptions, it is necessary to develop an instrument for measuring consumer perceptions of the option to purchase RTE Product at convenience stores. Variables used in this research are the perception and knowledge of the public/consumers against food safety, store attributes, service, and product attributes. The instrument used in this study is a questionnaire with a scalemeasuring1-5 to see the relationship between variables, we used the method of Structural Equation Modeling (SEM). The sample used in this study was 223 respondents that were divided into five areas in Jakarta, namely Central Jakarta, West Jakarta, South Jakarta, East Jakarta, and North Jakarta. The final outcome of the instrument development process was 25 observed variables, consisting of 4 indicators, which valid and reliable, with T-values for each observed variable is above 2,58, and Construct Reliability values range between 0,76 to 0,853.

Abstract

Increasing competition requires companies both large and small, to be more productive and innovative, therefore, companies need to be supported by an effective performance measurement system. In this research, the implementation of a balanced scorecard in SMEs engaged in the management of a restaurant, for a chance to be more superior and to compete amid the rapid development of the restaurant sector. Strategic map based on four perspective of Balanced Scorecard was defined, completed with agreement of strategic objective and measurement. This implementation give evidence that even with many limitations on SMEs, they have developed balanced scorecard, with adjustment based on condition for strategic objective performance indicator, so this performance measurement evaluation process is applicable and able to achieve the main objective, to provide information for continuous improvement process.
