The Corona Virus, or COVID-19, has become one of the world’s issues, not only affecting health but also the Indonesian economy. One of the sectors that has been impacted was micro, small, and medium enterprises (MSMEs), whose performance has decreased. Entrepreneurial marketing and innovation capability have proven to increase the performance of MSMEs. However, it was still questioned whether entrepreneurial marketing and innovation capability would increase performance during COVID-19 pandemic. We collected data through an online survey to 290 MSMEs in West Java. Statistical analysis using SmartPLS reveal that entrepreneurial marketing (opportunity-driven, proactiveness, customer intensity, risk taking, resource leveraging, and value creation) and innovation capability (product innovation, serve innovation, process innovation, and business model innovation) have a significant effect on the performance of MSMEs (profitability, productivity, domestic market share, profit margin, competitiveness of the MSMEs, ability to maintain profit margin, and rate owners satisfaction with innovation level). Innovation capability has a greater influence, with a value of 0.465, compared to entrepreneurial marketing, with a value of 0.156, on the performance of MSMEs. Serve Innovation and Process Innovation have a significant impact on the dimensions of innovation capability that contribute to MSMEs’ performance. Several practical and theoretical implications for entrepreneurs designing marketing strategies are discussed based on the findings.

Indonesia is a developing country with a low-level e-waste management system based on a limited number of informal initiatives. E-waste requires proper management procedures, which involve the design of a reverse logistics management network. Consumers play a critical role in such a network, because the network runs when they willingly participate as suppliers of waste. This paper applies the Theory of Planned Behavior framework and extends it using Reverse Logistics drivers, the Value Belief Norm Theory, and facility accessibility to explain consumer intention to participate in e-waste collection programs. A survey was conducted on smartphone users in Indonesia, with a total of 324 valid questionnaires. The results showed that government drivers, facility accessibility, and personal attitudes significantly influence consumer intentions. Environmental concern has a positive influence on consumer intentions through the variables of the Theory of Planned Behavior and perceived behavioral control through government drivers. This study shows the need for integration, because the variables reinforce each other. However, neither economic drivers nor subjective norms significantly influence consumer intentions. This finding distinguishes Indonesia from other countries, especially developed countries, in that e-waste collection programs have not become part of the culture in Indonesia. For this reason, Indonesia needs regulations, as the most influential variable, to regulate the implementation of such a program.

Evaluation of research management is essential in higher education The Indonesian government regularly evaluates the research performance, as part of improvement the research ecosystem in higher education system. This study aims to analyze the problems in implementing research performance evaluations in Indonesian higher education system This study used a qualitative method with Focus Group Discussion (FGD). The participants invited were leaders of research institutes at universities that represent the best college clusters. We conducted a four-stage FGD to obtain the required information. The results are answered with recommendations to rearrange the assessment and implementation model that is adapted to conditions in Indonesia. The author believes that this research will not only contribute to the scientific development but also provide assistance to international readers with insight into the research evaluation system in Indonesia, as well as policy-makers in implementing a better research evaluation system.

Understanding Gen Z’s purchase behavior in online travel agents is essential to effectively engage and meet the unique preferences of this generation, fostering long-term loyalty and satisfaction. Utilizing the unified theory of acceptance and use of technology (UTAUT) as the theoretical foundation, this study aims to analyze the impact of performance expectancy, effort expectancy, social influence, facilitating condition, and trust on purchase decision of flight tickets through online travel agent platforms. The data were collected through an online survey of 253 Gen Z users of online travel agent applications in Indonesia, such as Traveloka, Tiket.com, Pegipegi.com, Agoda, and Booking.com. The study employed PLS-SEM to test the hypotheses. The results indicate that performance expectancy, effort expectancy, social influence, and facilitating conditions influence trust (t-value 1.645, p-value < 0.05). Further, performance expectancy, effort expectancy, and facilitating conditions influence purchase decisions (t-value 1.645, p-value < 0.05). However, social influence does not significantly affect purchase decisions (t-value 1.041, p-value > 0.05). The analysis also shows that trust fully mediates the relationship between social influence and purchase decisions, while no mediating effect is identified in the relationship between effort expectancy and purchase decisions. By investigating the key factors contributing to Gen Z’s buying behavior in online travel agent platforms, this paper provides valuable insights for online travel businesses to effectively engage and cater to Gen Z’s unique needs and preferences.

Most people will store smartphone waste or give it to others; this is due to inadequate waste collection facilities in all cities/regencies in Indonesia. In Yogyakarta Province, there is no electronic waste collection facility. Therefore, an e-waste collection network is needed to cover all potential e-waste in the province of Yogyakarta. This study aims to design a collection network to provide easy access to facilities for smartphone users, which includes the number and location of each collection center and the route of transporting smartphone waste to the final disposal site. We proposed an extended maximal covering location problem to determine the number and location of collection centers. Nearest neighbor and tabu search are used in forming transportation routes. The nearest neighbor is used for initial solution search, and tabu search is used for final solution search. The study results indicate that to facilitate all potential smartphone waste with a maximum distance of 11.2 km, the number of collection centers that must be established is 30 units with three pick-up routes. This research is the starting point of the smartphone waste management process, with further study needed for sorting, recycling, repairing, or remanufacturing after the waste has been collected.
