| Abstract: | Setting and adjusting each component operating status of the conventional chiller plant is usually based on human judgment or control of Proportional-Integral-Differential (PID) based on pressure, temperature variables. Due to the lack of scientific, systematic and optimum logic basis, it is difficult to optimize the operation of chiller plant and control the excessive energy consumption with these methods. This study employs the Harmony Search Algorithm (HSA) to determine the optimum operation of each component within the plant to obtain the most energy-saving operation for maximum operation efficiency of the chiller plant, according to the actual required cooling capacity at load side, actual performance and operation condition of each component. The results reflect that the HSA can obtain the optimum solution and increase the Coefficient of Performance (COP) of the original chiller plantby6.25%. |

| Title: | Food Safety and Industrial Engineering Methods |

| Abstract: | The attention to food safety has increased over the past 15 to 20 years in many areas of the agricultural industry However, there are significant areas of the food industry that have not been adequately prioritized in relation to food safety research. This study emphasizes one of those understudied areas: small-scale, low-income minority farming communities. An industrial engineering-based supply chain management approach is proposed as a method for addressing food safety concerns in this agricultural demographic. The current article discusses an approach that centers around traceability technology as a means of providing heightened visibility and accountability within the food supply chains of farmers within this community. The persistent reality of food recalls is an unfortunate and frequently occurring circumstance in many categories of industry (example: technology, pharmaceutical, agriculture, etc.) of supply chain-based service and production industries. Consequently, the subsequent corollary of potentially critically damaging economic effects to businesses necessitates the need for better proactive and reactive approaches for preventing and reducing the effects of necessary recalls. This is especially essential for farmers and the communities they serve. The economic effects are heightened for smaller enterprises such as small-scale, limited resource minority farmers. Many farmers and value-added producers have not been proactive in pursuing the use of newer technologies such as radio frequency identification technology (RFID) or other traceability technologies for several reasons: fear of the unknown, a lack of a realization of their importance to the life of their businesses, and a lack of money. The ultimate goal is to make local, national, and global food supplies more secure. |

| Abstract: | This study was conducted on Bombax costatum calyx obtained from Yandev Community of Gboko Local Government Area of Benue State, Nigeria. Flowers were collected from a chosen tree as they dropped without the influence of any human activity. Calyxes were collected and sun dried to 5.5%wb for the study. The dried samples were milled and sieved using sieve of 0.25mm aperture to achieve uniform particle size. Bombax costatum samples were stored in different containers namely; plastic, glass, ceramics, metal and control. The proximate composition analysis of samples was performed to check the nutritional composition of Bombax costatum calyx using the AOAC method. The result presented carbohydrate, protein, moisture, fat, ash and fibre to have 78.30, 7.25, 5.50, 1.85, 3.30 and 3.80% respectively. Microbial and bacteria counts were performed before and after storage, to check the level of Microbes infestation and spoilage before and during storage. The mean Total viable counts (TVC) in this study across dilutions and containers showed that Plastic ranged from 3.55logcfu/g-1- 7.12logcfu/g-1, glass ranged from 3.57logcfu/g-1 – 6.98logcfu/g-1, metal ranged from 3.60logcfu/g-1 to 7.04logcfu/g-1, and ceramic ranged from3.59logcfu/g-1 – 7.27logcfu/g-1,the control had TVC ranged from 4.15logcfu/g-1-7.95logcfu/g-1. In line with HACCP-TQM technical guidelines, both the sample before storage and samples in containers after storage belong to the category of good food with glass presenting the best protection, followed by metal, ceramic, plastic and lastly control |
