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.

Abstract

This research aims to analyze and design the layout of production areas based on Lean-Green (L&G) Thinking in Micro, Small and Medium Enterprises (MSMEs) Scale Companies. By focusing on operational efficiency and sustainable production processes, this research can help MSMEs increase their competitiveness in an increasingly competitive market. To support this goal, researchers used the Systematic Layout Planning (SLP) method combined with the Promodel 6.0 simulation tool. The SLP method helps in evaluating the current MSME layout system and identifying areas that can be made more efficient by considering the criteria of distance, time and electrical energy consumption. Meanwhile, simulation techniques are used to help formulate appropriate lean-green strategies to increase process efficiency and minimize environmental impacts. Evaluation of the company's current layout resulted in an increase in operational efficiency of 1.55%, a reduction in inventory of 83%, and a reduction in electricity consumption of 26%. This research recommendation includes concrete steps to improve the layout of production areas that support MSMEs to become agents of change that combine operational efficiency with environmental responsibility.

Abstract

Lean and Green is well-known as an emerging paradigm in the industry to increase competitiveness with minimal environmental impact. A small and medium-sized cosmetics company in the Depok area has implemented programs based on lean and green concepts in stages since 2019. Currently, the company does not have sufficient skills and knowledge to carry out independent evaluations. The company also does not yet have a holistic and structured reference evaluation model. This research aims to assist decision-makers in SMIs in comprehensively evaluating the implementation of lean and green concepts. Researchers use the Context, Input, Process, Product (CIPP) model in the evaluation concept design with the in-depth interview (IDI) technique. The results of the study show six indicators that need improvement. Researchers propose two improvement activities that can ensure the sustainability of the lean and green program in the long term.

Abstract

Jakarta, Indonesia's bustling capital, is grappling with escalating air pollution levels attributed to a confluence of socio-economic and infrastructural factors. This study employs Vensim modelling to project PM2.5 pollution trends through 2040, analysing the dynamic interplay among major contributors: increased vehicular emissions, industrial activities, public transportation deficiencies, and waste management inefficiencies. Materials and Methods: The method that will be used in this air pollution analysis is to integrate empirical data spanning three years to construct a predictive model underpinned by a robust causal loop diagram that elucidates the relationships between system variables and air quality. The results of this paper indicate a projected 50% increase in PM2.5 levels by 2040 if current trends persist, with vehicular emissions being the predominant contributor, accounting for 67.4% of the increase. This underscores the critical need for stringent emissions standards and comprehensive enhancements to public transportation infrastructure. The study's simulations suggest that without significant policy interventions, air quality will continue to deteriorate, posing severe public health risks. Discussion points emphasise the model's implications for environmental policy, advocating for targeted measures to curb vehicular emissions and promote sustainable urban planning. Comparisons with existing literature highlight the study's contribution to understanding localised pollution dynamics, providing a granular analysis that aligns with global research trends. This paper aims to call for immediate action to implement rigorous environmental policies and infrastructure improvements to mitigate air pollution effectively. These strategies include enforcing stricter emissions standards, expanding public transportation networks, and integrating sustainable technologies across transportation and industrial sectors. This research not only maps a trajectory of Jakarta's air quality but also frames a policy response model that could guide similar urban centres globally facing air pollution challenges.
