Abstract

Inefficiencies in construction projects, aside from being caused by poor planning and control, are also attributed to delays in material delivery, especially for critical materials. One of the main causes of these delivery delays is suboptimal supply chain management. Therefore, it is essential to evaluate supply chain performance to identify and address these issues. Supply chain performance evaluation can utilize the SCOR 12.0 model, which has been widely applied in the manufacturing industry. A case study was conducted on the Semarang–Demak Toll Road Project Package 2, focusing on two key materials: precast full slabs and ready-mix concrete. The evaluation of supply chain performance employed the SCOR 12.0 model, which covers dimensions of reliability, responsiveness, agility, costs, and assets, as well as best practices implemented within the project. The research used a qualitative methodology, collecting data through questionnaires designed to assess supply chain performance indicators based on the SCOR 12.0 model, adapted for the construction context, and conducting interviews with project stakeholders and suppliers. The findings from the questionnaires and interviews were used to validate key performance indicators (KPIs), which were then scored on a Likert scale with five levels (5 = excellent, 4 = good, 3 = average, 2 = poor, 1 = very poor). The results of the supply chain performance assessment showed a score of 3.53 (good) for precast full slabs and a score of 3.8 (good) for ready-mix concrete.

Abstract

Single-use plastic consumption was so high that it led to a buildup of plastic waste, threatening the sustainability of ecosystems and marine life. Much of this plastic waste originated from environmentally unfriendly products, which had become an increasingly pressing social issue. This study investigated the impact of green product attributes, perceived price, and environmental awareness on consumers' purchase intentions for green products. Data were collected through a survey of 250 randomly selected respondents and analysed using descriptive statistics, validity and reliability tests, and Partial Least Squares Structural Equation Modelling (PLS-SEM) to assess both measurement and structural relationships. Validity tests were conducted using product-moment correlation analysis, and reliability was measured using Cronbach's alpha coefficient. Hypothesis testing was carried out with the help of PLS-SEM software. The results showed that Attitude Toward Green Brand and Price & Value Perception positively and significantly influenced Green Purchase Intention, with regression coefficients of 0.232 and 0.198, respectively. However, environmental awareness did not significantly influence GPI, with a p-value coefficient of -0.052. This research provided important insights for developing green product marketing strategies, emphasising the importance of strengthening product attributes and perceived value to increase consumer purchase intentions. Theoretically, the findings extended the understanding of consumer behaviour in green marketing by confirming that perceived product value mediated the relationship between environmental concern and purchase intention, thereby enriching existing models of sustainable consumption.
