Socio-economic impacts of the COVID-19 pandemic on waste bank closed-loop system in Surabaya, Indonesia.

The COVID-19 pandemic has caused most waste recycling activities to be terminated due to several factors, such as concerns about the spread of coronavirus through the collected solid waste. This study investigates the socio-economic impact of the situation of the closed-loop system of solid waste recycling. Several recommendations for tackling this problem are presented in this research. Primary data collection for the waste bank and informal recycling sector was carried out in the eastern part of Surabaya during large-scale social restrictions. In-depth interviews were conducted with waste bank customers, waste bank unit representatives and the informal recycling sector to understand the pandemic's socio-economic impact on the closed-loop system. Results show that this pandemic has significant impacts on individuals and stakeholders engaged in waste recycling activities. Customers of waste banks, who mostly belong to low-income communities, mentioned that the waste bank closure gave rise to social and economic problems, such as increasing unmanaged solid waste and decreasing income. This result also applied to the informal recycling sector. The government can use the recommendations in this study to generate related policies, such as enforcing the health protocol within solid waste management to keep the recycling system in place and the business alive.

Does entrepreneurship education promote vocational students' entrepreneurial mindset?

This paper aims to explore how entrepreneurship education determines students' entrepreneurial intentions as well as examine the emerging role of the entrepreneurial mindset in supporting this relationship. A quantitative method was applied to gain a better understanding of the relationship between variables utilizing Structural Equation Modeling (SEM) based variance Partial Least Square (PLS). The participants of this study were recruited from several vocational students in East Java of Indonesia by using an online survey. The findings indicate that entrepreneurship education positively influences both students' entrepreneurial intentions and an entrepreneurial mindset. It also reveals a robust correlation between entrepreneurship mindset and students' entrepreneurship intentions. Lastly, this study's finding shows that the entrepreneurship mindset has successfully mediated the relationship between entrepreneurial education and students' entrepreneurial intention.

Antihyperglycaemic and tissue-repair effects of Myrmeleon formicarius extract in streptozotocin-induced diabetic mice.

OBJECTIVES: In this study, we aimed to investigate the effects of oral administration of Myrmeleon formicarius (antlion) extract on liver and kidney histology in streptozotocin-induced diabetic mice. METHODS: Twenty-four mice received a single intraperitoneal injection of streptozotocin and were then divided into six groups. Untreated diabetic mice served as the negative control group, and glibenclamide-treated mice served as the positive control group. Mice in the other four groups, namely T1, T2, T3, and T4 groups, received M. formicarius (antlion) extract at 2.5, 5, 7.5, and 10 mg/kg, respectively. Permanent thin sections were used to examine liver and kidney histology. RESULTS: The most appropriate antihyperglycaemic dosage of the M. formicarius extract was 10 mg/kg for 2 days. Histological examination of the liver and kidneys showed that the antlion extract at 10 and 5 mg/kg exhibited significant tissue-repair effects. CONCLUSION: M. formicarius (antlion) extract can not only reduce blood glucose levels but also repair hyperglycaemia-induced tissue damage.
