The corner point singularity of surface cracks by finite element method (FEM) has become a numerical concern decades ago. The literature showed that the stress intensity factors (SIFs) at the corner points were often excluded. Further, most SIFs were reported for larger ratios of the crack depth over cylinder diameter. This paper presents the SIFs (Modes I, II and III) of a semi-elliptical surface crack at a solid round bar under torsion. The tetrahedral and hexahedral elements were used in the finite element modelling. The effects of the loading mode and the crack aspect ratio on the corner point singularity were discussed. The tetrahedral meshing was generally observed to be more suitable for modelling relatively small surface cracks, particularly in respect to the corner point singularity. For all loading modes, the SIFs away from the corner points of using the tetrahedral meshing were found to have fairly good agreement with those by dual boundary element method (DBEM).

Millennials are the generation that lived in the era of information technology revolution with the emergence of the internet and smart phones. Because of this experience, millennial has become an important element for human resources to meet industry 4.0. However, it is not clear how older leadership behaves on this generation and what impact they have on organizational performance. Thus, this paper focuses on investigating the effect of openness on millennial employee style on leadership effectiveness and its impact on 4.0 organizational performance. Survey is conducted on 224 millennial employees working in various companies in Indonesia. Data are analyzed using Smart-PLS 3.0 based on structural equation modeling (SEM). Our results showed that openness to millennial employee style had a positive effect on 4.0 organizational performance partially mediat-ed by 4.0 leadership effectiveness in industrial settings. These results confirm the role of millennial in shaping organizational performance and how managers need to implement appropriate measures to manage millennials and be open to various characteristics of this generation.

Research on marketing performance has been discussed by several previous researchers on institutions and industries. One of them is in the field of education. The purpose of this study is to analyze the effect of brand image toward marketing performance, brand image on trust and brand image toward marketing performance mediated by trust. In previous studies there have been many studies that measure marketing performance from internal or management perspective. On the other hand, this research discusses marketing performance that can be measured through the perspective of the student as consumer. This research studies the marketing performance of private higher education in the perspective of students in the Indonesian context. This research was conducted in DKI Jakarta. In this study it was found that there was not a significant influence on brand image toward marketing performance; brand image has a significant influence on trust and also trust towards marketing performance; but brand image has a significant influence toward marketing performance mediated by trust.

Gamification is an educational approach to motivate and influence students’ behaviors in learning with the intention of achieving learning outcomes. The primary objective of the study is to examine students’ intentions to become entrepreneurs as an impact of gamification model learning in Entrepreneurship or Business Plan courses in BINUS ONLINE Learning. Data collection was carried out for 400 students who took Entrepreneurship and Business Plan courses for 1 month using questionnaires. The data was then analyzed using multiple linear regression approach. The result shows that attitude towards behavior (ATB), perceived behavior control (PBS), and subjective norms partially give positive impacts and they are significant to entrepreneurial intentions. Perceived behavioral control (PBC) is the dominant factor in forming entrepreneurial intentions for students.

The major objective of this study is to analyze the effect of the shopping environment and situation as perceived by modern retail shoppers into perceived crowding, store image, and shopping motives toward emotions and repurchase intention in the context of a grocery modern retail. The cross-sectional design method was used in this study, and the data were collected from a customer survey with randomly selected 244 respondents using an online questionnaire. According to the findings the perceived crowding, store image, and shopping motives affected positively on the customer emotions. The perceived crowding was revealed as the most influential variable on the emotions. We also found a direct effect of perceived crowding and store image on repurchase intention. Furthermore, the high-density retail condition shoppers tend to feel pleased with the shopping environment and give a positive appraisal to the store image. But unfortunately, a high-density retail condition could discourage the shoppers to have repurchase intention. Interestingly, when the emotions were used as a mediating variable of perceived crowding and repurchase intention, those independent variables affected on repurchase intention, positively. Therefore, the shoppers' emotions were the most important factor affected on repurchase intention in modern retail. The more they enjoy the shopping environment and situations, the more they are interested in making future purchases.

Fresh produce which are part of agricultural products that can survive during the pandemic in Indonesia, there is even an increase in supply, this contribution is important for the availability of these products in maintaining consumption needs in maintaining public health levels in the midst of an unfavourable situation for all parties, including sustainability of business in this chain network. However, the development of this commodity still has many obstacles, especially in the ability to provide high-quality products, resource capabilities and manage existing information, especially the farmers who are involved in cooperation in this supply chain system, so that it can impact their performance. This study explores the mediating effect of collaborative performance systems (CPS) in lateral collaboration structures such as; information sharing (ISH), resource sharing (RSH), contract farming (CTF) and join mode transportation (JTM) in individual companies (CIP) and supply chain performance (SPO) in the fresh produce supply chain (FPSC). The sample in this study was taken based on purposive sampling from the participation of respondents in the FPSC network consisting of farmers producing fresh vegetables and fruits who are members of the Association of the Farmers Groups (Gapoktan), distributors, owners of transportation modes and supermarkets. Respondents consisted of 72 people who had filled out complete questionnaires from their four supply chain channel partners. Data collection methods were analyzed using a structural equation approach. The results of the study that the mediation of CPS on the performance of CIP and SPO in the FPSC was confirmed.

Supply chain management has attracted business interest in recent years. This interest is also driven by the development and spread of e-commerce technology. Because e-commerce is a relatively new phenomenon in business, little research has been done on its impact on supply chain relationships. E-commerce allows supply chain management to make collective decisions considering the interests of relationships with diverse and often competitive trading partners. The e-commerce environment is difficult to predict due to the vast availability of information and changing market dynamics. Management can deal with uncertainty more effectively when focusing on administrative partnerships as part of their corporate strategy. This quantitative and qualitative study with e-commerce businesspeople aims to: 1) highlight the strategic and tactical importance of supply chain assessment in e-commerce; and 2) describe future research opportunities in this new multidisciplinary approach.

The purpose of this study was to determine the effect of ship worthiness and seafarers' skills on improving ship operational performance through minimum service standards. Some early indications found in the field, such as the low performance of ship maintenance by procedures, and the obstacles in implementing the ship maintenance plan due to the inefficiency of the ship's operating schedule. This study uses Path Analysis with Path Coefficients Sub Structure 1 and Sub Structure 2. The test method used for the direct effect is the regression method while the indirect effect is the Sobel test. The number of samples is 80 respondents from national shipping companies, from various types of ships, namely, crew boats, patrol boats, utility boats, supply vessels, and anchor handling towing supply. The results of the study indicate that there is a positive and significant effect of seaworthiness and seafarers' skills on increasing ship operational performance, directly or indirectly through minimum service standards. The minimum service standard variable can mediate the indirect effect of the seafarers' skill and ship worthiness variables on the operational performance of the ship. To meet the growing customer satisfaction as the consequences of tight competition, it is necessary to improve the quality of the fleet where durability, cleanliness of the fleet, and safety facilities in the fleet are expected to provide a high guarantee for safety.

This study aims to analyze the effect of supply chain management sustainability and organizational learning ability on company performance which is also measured by intervening variables of product design innovation and competitive advantage and moderated by environmental uncertainty. This study used a sample of 383 companies from a population of 5,495 in East Java Province, Indonesia. This study also uses a quantitative approach with more emphasis on social aspects with a deductive model. Some of the findings in this study are that there is no significant effect on company performance and organizational learning ability if mediated by product design innovation, even though this is very important for the company's progress in the future and proves that many companies in this province. have not fully implemented design innovation as a measure of the quality of the goods produced. And the second is that all the components of the variables analyzed produce significant values for all dependent variables so that the adjustment to the impact of the pandemic gets a good response from the industry that is working.
