Indonesian SMEs compete globally for profits, market share, and needed resources. However, the performance of SMEs can be influenced by current economic conditions, the Covid-19 pandemic has caused SME revenue turnover to decline due to economic constraints, a decrease in people's purchasing power, and the power of online marketing not maximized. The solutions that come to mind are the development of social capital, knowledge sharing, and applying innovation in business operations. This study aimed to determine whether social capital, knowledge sharing, and innovation have a direct or indirect effect on the performance of SMEs, especially in the coffee industry in Purworejo Regency, Central Java. Respondents in this study were 33 SMEs of the coffee industry in Purworejo, Central Java. Data were obtained from questionnaires and data analysis using the multiple regression method with F test, partial t-test, and coefficient of determination test (R2). The results show that social capital, knowledge sharing, and innovation significantly affect coffee SMEs' performance in the Purworejo industry. In contrast, partially, social capital and innovation have a significant effect on the performance of SMEs. On the other hand, knowledge sharing has no significant effect on the performance of SMEs.

This study analyzes micro, small and medium enterprises (MSMEs) implementing supply chain management (SCM) practices between suppliers, manufacturers, distributors, and customers to encourage supply chain performance and good firm performance. This data collection was obtained from interviews and questionnaires conducted in parallel. The sampling technique used is purposive sampling, with 50 MSMEs – determination of the samples based on considering MSMEs that have implemented SCM practices. The analytical tool used is a path analysis model. The variables used in this study are aspects of SCM practices: customer relationship management, supplier relationship management, goal congruence, and information sharing. The results show that the dimensions of SCM practices partially positively influence firm performance and supply chain performance. Unfortunately, supply chain performance cannot mediate SCM practices on MSMEs performance. The supplier relationship management variable is considered to have the lowest value among other variables. Suggestions of this research that MSMEs can make are expected to work together with suppliers to improve product quality, such as evaluating product raw materials from suppliers, as well as routinely making continuous product improvements to maintain product quality owned by MSMEs.

Sustainability performance as measured through environmental, economic, and social performance, could be a competitive advantage for organizations amid the current tight business competition. Green Supply Chain Management (GSCM) practices which consist of green purchasing, green manufacturing, green marketing, green distribution and packaging, internal environmental management, environmental education, and investment recovery, could be a way for organizations to obtain their sustainability performance. This study aims to examine the impact of GSCM on sustainability performance of natural-dyed batik SME in Yogyakarta Province. The data were collected using questionnaire and later obtained 39 respondents who were selected by using area sampling technique. The data were analyzed descriptively and quantitively using Partial Least Square (PLS) with SmartPLS 3.2.8 software. The results of the analysis show that green purchasing, green manufacturing, green marketing, internal environmental management, and environmental education affect SME’s environmental, economic, and social performance positively and significantly. On the other hand, green distribution and packaging as well as investment recovery do not have positive and significant impact on SME’s environmental, economic, and social performance. The conclusion of this study is that the adoption of GSCM practices does not affect the overall SME’s sustainability performance, yet affects individually.
