Thus, sustainability should be implemented in achieving a sustainable campus. Evaluating the implementation of sustainable campus become a need to achieve a higher performance. This paper develops a structural model for sustainable campus assessment conducted to a case of Andalas University. It begins with identification of KPIs of sustainable campus assessment through literature study. Interpretive Structural modeling (ISM) method is applied to determine the interrelationships amongst the categories of KPIs. The results indicated setting and infrastructure, energy and climate change, waste, and water as the basic categories, while transportation and education appears to be the leading categories.

The development of entrepreneurship and technology-based business start-up trends is one solution to these problems. Universitas Andalas organizes The Entrepreneur Lecture Series regularly in the form of knowledge sharing by business persons and entrepreneurs to support those trends. A study to investigate the effectiveness of knowledge sharing conducted through the Entrepreneur Lecture Series in improving engineering students' technopreneur capabilities and individual innovation behavior. Data collected through a survey of engineering, agricultural, and information technology students. Analysis carried out with SEM-PLS, while the mediating effect of individual innovation behavior tested using the Sobel Test. The test results show that knowledge sharing conducted through the Entrepreneur Lecture Series has a positive influence on improving the technopreneur capabilities of engineering, agricultural technology, and information technology students. However, the effect is still relatively weak. Efforts are needed to improve the effectiveness of knowledge sharing. Further testing is required to determine the effect of knowledge sharing through the Entrepreneur Lecture Series on individual innovation behavior.

For the system to work, a damage indicator that describes the structural integrity level should be established and monitored. The damage indicator is usually derived from structural responses. Many quantities have been proposed for damage indicator including natural frequency, mode shape, curvature, strain energy, and t-, F-, and z-statistics. In this paper, we propose a new damage indicator in the time and frequency domains derived from the Euler-Bernoulli beam theory. We evaluate the method by using data obtained from a numerical simulation of a cracked beam. The beam deformation is nonlinear due to the contact between the crack faces during vibration. The proposed damage index is estimated in the domains for various observation points on the beam. Besides, the existence of the crack is also predicted by the widely used traditional method based on the change of the natural frequency and mode shape. A comparison is made between the present method and the existing ones. We conclude the present proposal is more sensitive to detect the crack.

The main reason of this tool design was due to the worker’s complain of feeling pain during the feeding process. Evaluation was performed based on Nordic Body Map questionnaire result, physiological workload, and NIOSH lifting equation calculation. The observed work ranged from the feed filling in the basket until all feeds were distributed. The results showed that the %CVL was in the range of 18%-30% and the energy consumption of workers was in the range of 1.24-3.00 Kcal/minute. Thus, physiologically, the work activities carried out by the feed workers were categorized as very light workload. Meanwhile, evaluation using Lifting Index (LI) methods in the process of feeding showed the LI value ranged from 0.9-1, therefore this activity is safe to perform manually.

An evaluation is essential to achieve a successful closed-loop supply chain. This study aims to evaluate the closed-loop supply chain performance in the bottled water industry using a fuzzy rule-based system. A case study is conducted to PT X, a bottled water company in West Sumatra. The results show the overall closed-loop supply chain performance of PT X is at a fair level. Nine measures in the forward chain are at a good level. In contrast, one measure (i.e., product characteristics) is classified into a poor level. Based on the results, the company needs to conduct improvements related to product characteristics. In terms of the reverse chain, two measures (i.e., material features and supplier commitment) are at a fair level, while four measures are at a good level. The company has to pay more attention to material features and supplier co...

Port performance is measured by eight indicators, while the supply chain connectivity measured by seven indicators, and national economic growth measured by the Gross Domestic Product (GDP) constructs. Linear regression analysis is used to identify the relationships developed based on three hypotheses. The study c...

An evaluation is essential to achieve a successful closed-loop supply chain. This study aims to evaluate the closed-loop supply chain performance in the bottled water industry using a fuzzy rule-based system. A case study is conducted to PT X, a bottled water company in West Sumatra. The results show the overall closed-loop supply chain performance of PT X is at a fair level. Nine measures in the forward chain are at a good level. In contrast, one measure (i.e., product characteristics) is classified into a poor level. Based on the results, the company needs to conduct improvements related to product characteristics. In terms of the reverse chain, two measures (i.e., material features and supplier commitment) are at a fair level, while four measures are at a good level. The company has to pay more attention to material features and supplier co...

This made the industrial world's development in work competition, not linear and even created new jobs. Digital talent and innovation are needed to face the world of work. This study discusses the construct effect between digital talent, individual innovation behavior, and Skills Revolution Industry 4.0, and the effect of Skills Revolution Industry 4.0) as a mediator to digital talent constructs' relationship. Data collection is obtained directly (face to face). Samples were previously clustered by sampling technique. Questionnaires use the Likert Scale. Then, the data gotten were processed by SEM-PLS with Software 3.8.2. The result showed that digital talent has a positive effect on individual innovation behavior. This meant that skill of revolution industry 4.0 as a construct mediator was successful. The stronger digital talent influences, the ...
