Justine","doi":"10.26437/ajar.v10i1.688","DOIUrl":"https://doi.org/10.26437/ajar.v10i1.688","url":null,"abstract":"Purpose: This study investigated the promotion of rural entrepreneurship in Tanzania through empowering Voluntary Financial Saving Groups (VFSGs). Specifically, the study examined practices adopted by VFSGs and challenges confronting such VFSGs. \u0000Design/Methodology/Approach: A cross-sectional study using qualitative and quantitative approaches was carried out using a sample of 262 members of VFSGs that was selected using proportionate stratified sampling from different strata. The study was conducted in the Iringa region, whereas the Iringa and Kilolo districts were purposefully selected. Questionnaires, in-depth interviews, and focus group discussions were employed as data collection methods. Qualitative data analysis was carried out using content analysis. Descriptive statistics were adopted for quantitative data analysis, whereas mean scores were performed, followed by ranking. \u0000Research Limitation: This study was limited to one geographical region, Iringa, with only two districts, Iringa and Kilolo. The limitation was attributed to limited time and financial resources to cover a wider scope. \u0000Findings: Major findings of the study regarding practices adopted by VFSGs included inadequate training on enterprise development and management for members of VFSGs and inadequate seriousness to punish loan defaulters. Further, major findings about challenges facing VFSGs were the small amount of loans provided to members, inadequate business training to members, late loan repayment, the high dropout rate of members, unfavourable entrepreneurial cultures among members, conflict emerging among members and poor attendance in a meeting among members of VFSGs. \u0000Practical implications: The study concludes that skills gaps and loan defaulters in VFSGs are practices that are less adopted. This calls for intervention through entrepreneurship and business training and further longitudinal studies to establish behavioural change over time after intervention. \u0000Social Implication: Policies should mandate the provision of business training to VFSGs before they receive loans from money lenders. They should also focus on reducing mobile money transactional charges to fuel technology usage among VFSGs. \u0000Originality: The empirical data gathered from various regions in rural Tanzania adds valuable, real-world evidence to the discourse on VFSGs and rural entrepreneurship.

The sample size for the WMAs selected as the cases for the study were two (2), Tunduru and Mbarang’andu purposefully selected. Further, the sample size for WMA leaders was 20 (50% of the population) purposefully selected. Descriptive analysis was used to summarise demographic and revenue data, and a Pearson Chi-square test was performed on the demographic data. A paired samples T-test was used to compare the required business start-up and available funds to reveal the equity gap in the two WMAs and compare the level of implementation of planned business activities in the two WMAs. \u0000Research Limitation: The research was limited to two WMAs and a small sample size since the client determined its size, given that this paper emanated from the consultancy project. \u0000Findings: Findings indicate that both WMAs have a high potential for carbon trading, photographic tourism, beekeeping, fish farming, and heritage tourism. The difference in the required funding and available funds for various expenditures in business start-ups was found to be statistically significant in both WMAs. The difference in the level of implementation of planned business activities was also found to be statistically significant in the two WMAs. \u0000Practical implications: To bridge the entrepreneurial gaps in the WMAs, proactive fundraising, diversification of income-generating activities, including carbon trading, human resource capacity building, and appropriate marketing of tourism and nature-based products are needed. \u0000Social Implications: The results of this research will form the basis for bridging entrepreneurial gaps in the WMAs, hence fueling optimal exploitation of entrepreneurial opportunities in wildlife that benefit the community at large in return. \u0000Originality: This paper is original; only some extracts were used in the conference proceedings for the University of Dodoma (UDOM) 2019.

The objective is to develop predictive models to help predict and attain optimised mechanical strength integrity of 3D printed parts.
 Design/Methodology/Approach: In the present study, 3D printed PLA samples were modelled and fabricated using carefully selected processing parameters-processing speed, processing temperature and nozzle diameter. Tensile tests were performed by ASTM D638 standard. Two characteristics response optimisation models based on Taguchi Technique and multi-linear regression models were developed to optimise the process parameters and the ultimate tensile strength of the 3D printed samples.
 Findings: Results of this study reveal that ultimate tensile strength is significantly affected by the Nozzle diameter. The ultimate tensile strength of the 3D-printed PLA sample was found to be significantly higher than the strength of the original PLA filament printed.
 Research Implications/Limitations: In this study, only three critical 3D printing processing parameters including, processing speed; processing temperature and nozzle diameter were implemented concurrently.
 Practical implication: The optimisation of process parameters for enhancing the tensile strength of 3D-printed PLA parts holds significant practical consequences, including cost savings, improved performance, sustainability, and innovation. The aforementioned consequences render PLA a more feasible and appealing material option for a diverse array of applications and industries.
 Social implication: Optimisation of PLA printing can promote community engagement by allowing individuals to bring their creative ideas to life, fostering a sense of community and innovation.
