The results of the study indicate that all hypotheses were accepted. Friendship factors, particularly interpersonal trust, play a crucial role in shaping perceived usefulness and experience confirmation, which in turn influence satisfaction and the intention to continue social shopping and social media participation. Conclusion: This study highlights the importance of providing positive experiences (positive confirmation) to encourage sustainable intentions in the context of social shopping and social media participation. Novelty/Originality of this article: The study introduces an adapted Expected Confirmation Model (ECM) to examine how friendship factors influence consumer satisfaction and continued intention in social shopping and social media participation
Integrating state-owned enterprises (SOEs), agro-economics, and sustainability: A systematic literature review on contract farming mechanism
Get PDFBackground: Contract farming has emerged as a strategic mechanism to bridge market access, reduce production risks, and empower smallholder farmers in agricultural economies. However, its effectiveness varies across institutional contexts, particularly in developing countries facing market failures and power imbalances. This study aims to systematically examine the integration of state-owned enterprises (SOEs) within contract farming mechanisms to enhance agro-economic performance and sustainability. Previous studies have primarily focused on private-led contract farming models, with limited exploration of public or hybrid institutional roles, especially those owned by local governments. Methods: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method, this study analyzes 19 peer-reviewed articles published between 2020 and 2025. Thematic synthesis is applied to identify key patterns related to institutional involvement, economic impact, and sustainability dimensions. Findings: The findings reveal that the integration of (SOEs) into contract farming can improve farmers’ access to production inputs, ensure price stability, and support inclusive participation in the value chain, particularly when supported by clear regulatory frameworks and participatory governance. Moreover, models involving public institutions tend to align more closely with long-term sustainability goals such as environmental preservation and rural social equity. Conclusion: This study concludes that BUMD holds untapped potential in reshaping the governance of contract farming systems toward more equitable and sustainable outcomes. Novelty/Originality of this article: The novelty of this article lies in highlighting the strategic role of local public enterprises such as BUMD in agricultural contracting, an area that remains underexplored in existing literature
The exemplary role of farmer institutional administrators as a strengthener for the holistic and integrative reform of the agricultural development paradigm
Get PDFBackground: The agricultural development paradigm, which has shifted evolutionary from traditional agriculture to the current sustainable agriculture stage, has not been able to create prosperity for both farmers and the environment. Since the establishment of this sustainable agriculture paradigm, the back-to-nature movement has not changed the fate of farmers and the environment. This condition indicates that the three pillars/dimensions of sustainable agricultural development have not been successful in economic, sociological, and ecological dimensions, because one of the causes is the role of farmer institutions is not optimal, including not being a role model for its members. The purpose of this study is to strengthen the impact of the implementation of a holistic and integrative agricultural development paradigm through the exemplary role of farmer institutions for its members. Method: method used is descriptive through the Literature Review (SRL) technique approach using several published and unpublished research articles. Some theories used are the history of the evolution of agricultural paradigms in Indonesia starting from the traditional stage, agricultural intensification, agricultural diversification and industrialization, sustainable and inclusive agriculture to the optional holistic and integrative paradigm and the theory of farmer group role models. Findings: The results of this study reveal that the role model factor of farmer group administrators can have implications for the level of farmer participation in following all recommendations. In line with the exemplary role model of farmer group administrators, this evolutionary paradigm shift in agricultural development toward a holistic and integrative one will positively impact the acceleration of improving the welfare of farming communities and their environment. Conclusion: The conclusion of this study is that the paradigm shift in agricultural development in Indonesia from before the 20th century to the 21st century (sustainable and inclusive agricultural development), including holistic and integrative options, has not been able to alleviate poverty in agriculture. Novelty/Originality of this article: A holistic and integrative sustainable agricultural development paradigm will have a very positive and accelerating impact on poverty alleviation in the agricultural sector if it strengthens the role of exemplary farmer institutions
