Ekstrak Enzim Protease dari Daun Palado (Agave Angustifolia) dan Pemanfaatannya dalam Proses Pembuatan Virgin Coconut Oil

Virgin coconut oil (VCO) can be made in several ways, namely through a heating process at low temperature, freeze-drying, fermentation, enzymatic, mechanical pressure or centrifugation. VCO with an enzymatic method is the making of VCO fromcoconut milk by using enzyme. The protein-oil bonds in the emulsions in coconut milk can be broken down into protease enzyme. The purpose of this research is to extract the protease enzyme in palado leaves and utilize the enzymes in the manufacturing process as well as determining the quality of VCO. This research method passed through some processes. Firstly enzyme extracts from palado leaves are prepared and coconut milk from coconut cream is made, then it is tested qualitatively the presence of protease enzyme with ninhydrin color reagent. Furthermore, the making of VCO enzymatically is undertaken by varying the ratio of the volume of coconut cream and enzyme extracts of 24 hours. VCO quality is analysis by using the parameters of smell, flavor, color, moisture content, levels of FFA (free fatty acid) and peroxide. The testing result with ninhydrin reagent gave a positive reaction (blue-purple) showing that there is enzymes alleged a class of protease in the palado leaf. The result of VCO made with the comparison of coconut cream and enzyme extracts from palado (10 : 1) has generate a VCO with a yield of 25.4%. However, from the analysis of VCO quality test results, it is obtained the smell of distinctive flavor oils, fragrance, the clean color, water content of 0.5% , FFA content of 0.25% and the peroxide number of 0 meq/kg

Beyond capitalism and liberal democracy: on the relevance of GDH Cole’s sociological critique and alternative

This article argues for a return to the social thought of the often ignored early 20th-century English thinker GDH Cole. The authors contend that Cole combined a sociological critique of capitalism and liberal democracy with a well-developed alternative in his work on guild socialism bearing particular relevance to advanced capitalist societies. Both of these, with their focus on the limitations on ‘free communal service’ in associations and the inability of capitalism to yield emancipation in either production or consumption, are relevant to social theorists looking to understand, critique and contribute to the subversion of neoliberalism. Therefore, the authors suggest that Cole’s associational sociology, and the invitation it provides to think of formations beyond capitalism and liberal democracy, is a timely and valuable resource which should be returned to

Is there life after degeneration? The organizational life cycle of cooperatives under a ‘grow-or-die’ dichotomy

This article provides an in-depth, longitudinal analysis combining real-time and retrospective data on a set of Mondragon's industrial cooperatives that are organized as international groups. We examine the life cycle of these international cooperative groups, which is expected to evolve differently to that of small- and medium-sized cooperatives that operate exclusively on a local scale. The article is theoretically informed by the cooperative life cycle theory, as well as by recent insights from the degeneration and regeneration theses. Our analysis yields an intricate picture of the evolution of cooperatives faced with a ‘grow-or-die’ dichotomy. On the one hand, our findings reject the highly simplistic and deterministic view of the degeneration thesis by demonstrating that these cooperatives can mobilize resources to revitalize cooperative values and practices. On the other, we find that regeneration may not occur in a consistent, sequential fashion as the previous literature suggests, but rather degenerative and regenerative tendencies can occur simultaneously, even leading to long-lasting, unresolvable situations. In light of this, the article asks future research to draw on power-aware and politically informed approaches for further understanding of how cooperatives manage the tensions at each organizational stage of their life cycle, and of which organizational actors benefit, and how, from reversing some degenerative tendencies while maintaining others intact

Communitarian perspectives on social enterprise

Concepts of social enterprise have been debated repeatedly, and continue to cause confusion. In this paper, a meta-theoretical framework is developed through discussion of individualist and communitarian philosophy. Philosophers from both traditions build social theories that emphasise either consensus (a unitarist outlook) or diversity (a pluralist outlook). The various discourses in corporate governance reflect these assumptions and create four distinct approaches that impact on the relationship between capital and labour. In rejecting the traditional discourse of private enterprise, social enterprises have adopted other approaches to tackle social exclusion, each derived from different underlying beliefs about the purpose of enterprise and the nature of governance. The theoretical framework offers a way to understand the diversity found within the sector, including the newly constituted Community Interest Company (CIC).</p

Managing and resisting ‘degeneration’ in employee-owned businesses: a comparative study of two large retailers in Spain and the UK

Employee-owned businesses have recently enjoyed a resurgence of interest as possible ‘alternatives’ to the somewhat tarnished image of conventional investor-owned capitalist firms. Within the context of global economic crisis, such alternatives seem newly attractive. This is somewhat ironic because, for more than a century, academic literature on employee-owned businesses has been dominated by the ‘degeneration thesis’. This suggested that these businesses tend towards failure – they either fail commercially, or they relinquish their democratic characters. Bucking this trend and offering a beacon - especially in the UK - has been the commercially successful, co-owned enterprise of the John Lewis Partnership (JLP) whose virtues have seemingly been rewarded with favourable and sustainable outcomes. This paper makes comparisons between JLP and its Spanish equivalent Eroski – the supermarket group which is part of the Mondragon cooperatives. The contribution of this paper is to examine in a comparative way how the managers in JLP and Eroski have constructed and accomplished their alternative scenarios. Using longitudinal data and detailed interviews with senior managers in both enterprises it explores the ways in which two large, employee-owned, enterprises reconcile apparently conflicting principles and objectives. The paper thus puts some new flesh on the ‘regeneration thesis’

The co-operative university: Labour, property and pedagogy

I begin this article by discussing the recent work of academics and activists to identify the advantages and issues relating to co-operative forms of higher education, and then focus on the ‘worker co-operative’ organisational form and its applicability and suitability to the governance of and practices within higher educational institutions. Finally, I align the values and principles of worker co-ops with the critical pedagogic framework of ‘Student as Producer’. Throughout I employ the work of Karl Marx to theorise the role of labour and property in a ‘co-operative university’, drawing particularly on later Marxist writers who argue that Marx’s labour theory of value should be understood as a critique of labour under capitalism, rather than one developed from the standpoint of labour
