Item QUALITY CONTROL ASSESSMENT OF BODY-MAKING PROCESS IN ALUMINIUM BEVERAGE CAN PRODUCTION(Covenant University Ota, 2025-01) AKEREKAN OPEYEMI ERNEST; Covenant University DissertationThis study focused on the analyses of the quality control process of aluminium beverage can production (sleek size – 330 ml) monitored over a period of time, by deploying six key parameters: Bright Can Axial Load, Finished Can Height, Flange Width, Groove Diameter after Reformer, Dome Depth with Reformer, and Finished Can Buckle. These parameters revolve around the standardization and specification of the beverage can for a sustainable food packaging process. The study employed Statgraphics Centurion (version VII) as a statistical tool for analyzing process stability and capability through Statistical Process Control (SPC) techniques. This software generated control charts (X-bar charts) and process capability indices (Cp and Cpk) to evaluate process performance and identify areas requiring improvement. Descriptive statistical measures such as process mean and standard deviation were calculated to support the analysis. The methodology also included thoroughly evaluating production line data, with variations in each quality parameter assessed against defined specification limits. Results indicate that the Bright Can Axial Load has a moderate capability (Cp = 0.82, Cpk = 0.75) with a slightly off-center mean. Also, the Finished Can Height show low capability (Cp = 0.30, Cpk = 0.25), indicating significant variability. Flange Width has moderate capability (Cp = 0.43, Cpk = 0.43), while Groove Diameter after Reformer presents a Cp of 0.60 but a very low Cpk of 0.06, reflecting a misaligned process mean. In addition to this, Dome Depth with Reformer shows moderate capability (Cp = 0.53, Cpk = 0.23), needing better centering. Finished Can Buckle demonstrates the highest capability (Cp = 1.63, Cpk = 0.74) with a slightly off-center mean. The findings imply that aligning process means with specification limits and reducing variability will ensure consistent, high-quality aluminium production. Thus improving the operation process and subsequent improvement in the overall productivity of aluminium beverage cans.Item ASSESSMENT OF THE UTILISATION OF SUSTAINABLE ENERGY AND ENVIRONMENTAL PROTECTION IN SOUTHERN NIGERIA(Covenant University Ota, 2025-01) OBANOR ENOCH IWINOSA; Covenant University DissertationThis study evaluates renewable energy adoption across Ogun, Lagos, Edo, and Delta states using a mixed-methods approach. A bibliometric analysis of 424 research publications (2014–2024) revealed that solar energy was the most studied topic (35%), followed by hydropower (25%) and bioenergy (20%). The analysis identified a 32% increase in renewable energy publications since 2019, with 62% of highly cited papers focusing on policy and deployment strategies. Citation mapping indicated that the top 10 research institutions contributed 47% of all renewable energy studies, highlighting the concentration of expertise in specific regions. Survey data from 387 respondents indicated that 68% lacked reliable electricity access, while 78% relied on traditional biomass or fossil fuels. Among respondents, 62% expressed willingness to adopt solar energy if installation costs were reduced by at least 40%. However, only 23% were aware of existing renewable energy policies, and 54% rated government efforts as inadequate. In terms of energy satisfaction, only 9% of respondents rated their current energy sources as highly adequate, while 36% described them as moderate, and 21% rated them as low. The study further analysed energy availability across Nigerian states. Lagos, Ogun, Edo, and Delta states experience an average of 12–18 hours of electricity outages per day, forcing 74% of households to rely on generators as backup power sources despite Nigeria’s solar radiation potential of 3.5–7.0 kWh/m². Alignment with Sustainable Development Goals (SDGs) 7 and 13 was assessed, revealing that only 19% of publications explicitly addressed energy access and climate change mitigation, while survey results showed that 69% of respondents were unaware of Nigeria’s commitment to SDGs. Projections based on current adoption rates estimate that, if key policy recommendations, energy access in Southern Nigeria could rise from 32% to over 70% by 2035 and fossil fuel dependency could decline by 55%. This research shows that achieving an efficient renewable energy transition requires urgent policy interventions, enhanced financial incentives, and strengthened institutional frameworks.Item A comprehensive review of biofuel utilization for household cooking in developing countries: Economic and environmental impacts(Process Safety and Environmental Protection Volume 191, Port A,, 2024-11) Dirisu joseph 0.; Oyedepo Sunday 0.; Olowole Olukunle C.; Somefun Tobilobo E.; Peter Nkoliko J.; Babatunde Damilola; Nwaokocha Collins N.; Onokwai Anthony 0.; Obano Enoch; Alam Md Mahbub; Kale Sandip A.Item Pillars of Effective and Efficient Energy Systems in Nigeria(International Conference on Energy and Sustainable Environment (IOP Conf. Series), 2021) Fayomi O. S. I.; Banjo S.O.; Agboola O.; Oyebanji J. A.; Udoye N. E.Nigeria is posed with a myriad of challenges to achieving efficient energy systems; the colossal collective demand for sufficient electricity for approximately 200 million is a concern. Another challenge is the mismanagement of Nigeria’s abundant resources, by individuals and by groups. It has withheld us, for decades, from making the bold and rapid progress which ought to have made for the energy system. This report explores the concept of an energy system in Nigeria perspective and progresses.Item Corrosion Phenomena and the Occurrences; A comment(International Conference on Engineering for Sustainable World (IOP Publishing), 2021) Ayodeji A. I.; FayomiO.S.I.; Daniyan A. A.; Babaremu K. O.; Abioye P. O.; Agboola O.Corrosion refers to the deterioration of metallic materials resulting from the reactions between the components and their environe. However, corrosion occurs every day in the human world, both in industrial operations and domestically. This happens in different ways, making it well categorized into various types. This paper has concisely reported the basic phenomenon of corrosion, its environmental effect, and the various types like a crevice, pitting, erosion, and others. The Electrochemical behavior of corrosion was also reported as reactions that include oxidation and reduction reactions; oxidation reactions increase the valence number of materials by removing particles from the material, making them positively charged. In other ways, technological advancement has provided several attempts to understand this catastrophe, providing consistent mitigating measures and control toward attaining less cost. This overview studies the electrochemical corrosion phenomena and the prospect of materials selection in curtailing the ranging challenges.
