Abstract

High density polyethylene composite reinforced with natural plantain fiber was produced using injection moulding technique. The production process utilized the popular L18 Taguchi experimental design to investigate the effects of the major process variables such as barrel temperature, mold temperature, injection pressure, holding pressure, back pressure, clamping force and shaft speed in the final mechanical property of the composite material. The mechanical tests conducted on the new material reveal that fiber volume fraction of 0.1 combined with particle size of 75 μm and compactibilizer mass of 0.00024 kg gives a high-quality composite material suitable for auto body fender application, at reduced manufacturing cost of ₦1454/kg of the composite. The composite material produced at optimized process condition was found to have tensile strength of 87.44 MPa, yield strength of 76.6 MPa, flexural strength of 77.03 J, Rockwell hardness strength of 756.99, Impact strength of 16.21 J and density of 993 kg/m3. The result shows that the auto body fender produced based on the compactibilized plantain fiber reinforced high-density polyethylene composite has an advantage of low density and reduced production cost compared to conventional/alternative materials.

Abstract

Nigeria’s economy continues to face structural challenges such as low productivity, inadequate infrastructure, and limited diversification beyond oil. In this context, Information and Communication Technology (ICT) has emerged as a potential driver of economic transformation, offering new opportunities for growth, innovation, and competitiveness. The study population comprised 75 people, including 25 UBA Magadisu staff and 50 ATM cardholders. Using stratified random sampling through a hat-drawn method, 20 staff and 34 customers were selected, following Ndagi’s guideline for small populations. Data was sourced from questionnaires (primary) and internet documents (secondary). The questionnaire’s validity was ensured through supervisor review and reliability tested with a pilot study of 10 GTB staff. Data collection was facilitated by the HR manager, with respondents given five days to complete the instrument. Analysis employed mean scores for Likert responses, percentages for demographics, and chi-square to test significance. The results revealed a fairly balanced gender distribution with slightly more females than males, while the majority of respondents were within the 31–50 years age range. Findings showed strong support for the importance of ICT in Nigeria’s economy, with many agreeing that it contributes to growth and development. ICT awareness was also perceived as high, though doubts remained about its usefulness across all economic sectors. Chi-square analysis confirmed ICT’s significant contribution to Nigeria’s economic development. The study concludes that ICT is a transformative driver of progress in Nigeria, but its full potential can only be realized through enhanced awareness, equitable accessibility, and integration across sectors.
