EFFECTIVE SEDIMENT CONTROL IN A RESERVOIR

Sedimentation in a reservoir cannot be avoided. The average rate of sedimentation on the storage volume reduction of a reservoir in the world is about 1 % per year (Yoon,1992), meanwhile, the storage volume reduction in several reservoir in Indonesia reaches 1,64% to 2,83% per year (Atmojo,2012). These sediment’s accumulations in the reservoir will continually reduce the storage volume, thus the intended functions of reservoirs for flood control (Atmojo, 2013), irrigation and water supply, electric generation, etc. will also reduced and not optimal. Some of sediment control measures have been practiced in reducing sediment accumulation in reservoirs around the world. In principle, there are two approaches i.e., reduce the sediment input to a reservoir by land conservation, construction of check dam, sand pocket, diversion channel, etc. and reduce the sedimentation in the reservoir by sluicing, turbidity current, dredging, and flushing (Morris and Fan, 1998; Emamgholizadeh et al., 2006). This paper presents the performance of sediment’s reduction from a reservoir by flushing, sluicing, and disturbing flushing based on some laboratories results (Atmojo,2012). It is expected that this paper can contribute to elicits some finding on the selection of which suitable method for sediment reduction from a reservoir

Eco‐Holonic 4.0 Circular Business Model to Conceptualize Sustainable Value Chain Towards Digital Transition

The purpose of this paper is to conceptualize a circular business model based on an Eco-Holonic Architecture, through the integration of circular economy and holonic principles. A conceptual model is developed to manage the complexity of integrating circular economy principles, digital transformation, and tools and frameworks for sustainability into business models. The proposed architecture is multilevel and multiscale in order to achieve the instantiation of the sustainable value chain in any territory. The architecture promotes the incorporation of circular economy and holonic principles into new circular business models. This integrated perspective of business model can support the design and upgrade of the manufacturing companies in their respective industrial sectors. The conceptual model proposed is based on activity theory that considers the interactions between technical and social systems and allows the mitigation of the metabolic rift that exists between natural and social metabolism. This study contributes to the existing literature on circular economy, circular business models and activity theory by considering holonic paradigm concerns, which have not been explored yet. This research also offers a unique holonic architecture of circular business model by considering different levels, relationships, dynamism and contextualization (territory) aspects

The Relationship between Supply Chain Coordination and Quality Assurance Systems: A Case Study Approach on the German Meat Sector

The German meat industry faces a high demand for food safety and traceability. After several meat scandals in the recent past, efforts have to be made to regain consumer trust and to assure access to export markets. Apart from a few niche markets, there is no focal company in the German pork supply chain which efficiently coordinates food chain information, harmonizes the multiplicity of different IT systems or takes on professional public relations in charge of the whole sector. In cases of food crises, essential up- and downstream information slowly flows across the supply chain which hinders both seamless traceability and the harmonization of production processes between the various stages of the supply chain. This contribution focuses on the opportunities for more efficient coordination based on spot market environments. With reference to the theory of organization economics, a case study of the QS Qualität und Sicherheit GmbH as the leading certification scheme that addresses the German meat industry was carried out. Several non-classical certification activities which fall within the scope of coordination were identified with QS. Based on the assumption that the company continuously improves the coordination of the supply chain, there are opportunities for the meat sector as a whole which are pointed out in the conclusion.Agribusiness, Agricultural and Food Policy, Farm Management, Food Consumption/Nutrition/Food Safety,
