Abstract: Groundnut is a valuable crop with an excellent source of protein that can be used to fight hunger and malnutrition especially in underdeveloped and developing countries. Products such as oil, peanut butter, soups, roasted groundnuts among others can be obtained from groundnuts However, in developing nations especially Nigeria, roasting of groundnut, a means of moisture removal and food processing, has been associated with drudgery and bad hygiene (that is, use of sand, ashes as means of heat transfer). This can be a source of physical and microbial contamination to the product. Hence, the need for development and evaluation of a peanut processor that alleviate the problems associated with the process. Design, fabrication and performance evaluation of groundnut roasting machine were carried out at the AGE Workshop, Federal University of Technology, Akure, Nigeria. The factors considered for the design were; the volume of product to be roasted, reduction of heat loss, inclusion of stirrer and stable roasting temperature. Raw groundnuts were roasted with the fabricated machine and parameters such as weight of raw groundnuts, weight of roasted groundnuts, weight of seeds damaged were used to evaluate the efficiency of the machine. The effect of sand on the roasted groundnuts was also determined through microbial analysis, free fatty acids, peroxide value, tannin, flavonoid, phytate and phenol. The average percentage losses were 16.15% and 5.89% for traditional and mechanical methods, respectively. The traditional and mechanical methods recorded an average roasting efficiency of 83.85% and 94.11%, respectively. Both processing methods produced a product with considerable low moisture content. Processing time was reduced by 18 minutes when processed mechanically with significantly (p < 0.05) lower antinutrients and reduced microbial load. Mechanical processing of groundnuts is more efficient than traditional roasting in terms of time and overall quality of the roasted groundnut.

Abstract: Parking or facilities serving people's parking needs play a very important role in the planning and development of the road transport system, which have an important influence on the sustainable urban development objective of Ho Chi Minh City (HCMC). However, after many different efforts and solutions, the problem of solving parking demand in HCMC area has not been completely solved, the reason comes from many objective factors and especially vacant land fund for the infrastructure is very limited. Understanding the reasons leading to the failure of the applied solutions, the study focused on the proposal, synthesizing parking models with small and medium scale, with appropriate technical specifications. These technical specifications are proposed, based on the needs and characteristics of HCMC. Moreover, gathering a database of possible parking solutions is an important prerequisite for the City Government as well as the research units to continue the next research in order to create a comprehensive solution that could help solving the problem of people’s parking needs of HCMC.
