Uniformity of temperature in a room is often encountered in various purposes. This study presents the results of modeling the temperature and airflow in the chicken coop. A problem to be solved in this research is how to design the chicken coop in order to produce temperature uniformity. Thus, the objectives are to build a chicken coop dimensional model of 96x12x2 m with a capacity of 15,500 chicks. Modeling results analysis using CFD (Computational Fluid Dynamics). The stage of completion to meet the above objectives is by measuring the dimensions of the chicken coop. The next data to be obtained are temperature and air velocity to determine the boundary conditions. Some of the above parameters are used to validate chicken coop design. Modeling conducted using CFD methods with temperature and air velocity as boundary conditions. The modeling results showed that the average temperature in the chicken coop is adequate as an ideal temperature standard for chicken coop. Temperature uniformity is obtained by variation of the exhaust opening 4.
In the past few years, Indonesia is the largest exporter of plywood, the binding constraint in this case that Indonesia exploits neither advantages of being large resources country nor its dynamics competitive supply chain and ability to adapt with perceived environmental uncertainty. This study investigates whether perceived environmental uncertainty within supply chain performance affect intregated domestic economy. Predictable variables can be part of basis to solve integrated domestic economy and that variables can be considered by plywood manufacturer in Indonesia to respond to environmental uncertainty and supply chain itself. In this study, plywood manufacturer has been investigated as research samples, that its have SNI ISO 2426.2:2008. Multivariate analytical technique has been chosen with Warp PLS 3.0 and all samples have met the criteria composite reliability and cronbach's alpha. The study finds both of supply chain performance and perceived environmental uncertainty as predictor latent variables have positive impact, but supply chain performance had large effect sizes value explained, that supply chain performance plays an important role in improving practical perspective integrated domestic economy of plywood manufacturer in Indonesia and offer as one of a government or corporate attention to set regulations and to manage plywood supply chain policy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
