Abstract

The rapid expansion of urban areas in developing countries has significantly increased transportation demand, leading to air pollution and posing serious health and environmental risks. This situation calls for alternative fuels, especially in the transport sector. Thus, this study aimed to understand how vehicle owners within the city perceive the adoption of CNG as an alternative fuel in Dar es Salaam, Tanzania. A sample of 384 participants was selected using stratified and purposive sampling methods. Data collection involved questionnaires via Google Forms and interviews. The data were analyzed descriptively and inferentially using IBM SPSS version twenty seven (27) and Microsoft Excel, with both descriptive and inferential methods. Results indicate that while general awareness of CNG is moderate, those with direct experience have a much better understanding of its environmental and cost-saving advantages. Adoption is limited by technical knowledge gaps and infrastructure issues. Still, attitudes toward adopting CNG are mostly positive, driven by economic and environmental concerns. The study highlights the need for public campaigns and supportive legal and institutional frameworks to increase awareness and convert positive attitudes into actual use, offering valuable guidance for policy efforts to promote sustainable urban Transportation.

Abstract

This study examined the influence of staff responsiveness on passenger satisfaction in Tanzania’s Standard Gauge Railway (SGR) services. Staff responsiveness forms a critical component of service quality in transport operations, encompassing prompt assistance, courteous communication, and professional interaction between service providers and passengers. Using a mixed-methods approach, the study collected quantitative data from 117 passengers through structured questionnaires and qualitative data from key informant interviews. Quantitative results showed that respondents were generally satisfied with staff responsiveness, recording high mean scores for prompt response, courtesy, and assistance (mean values ranging between 3.81 and 4.13). However, regression analysis revealed that staff responsiveness had an insignificant statistical influence on overall passenger satisfaction (R² = 0.013; p > 0.05). Qualitative results complemented these findings, indicating that while passengers appreciated politeness and professionalism, responsiveness alone did not fully determine satisfaction due to communication challenges and limited staffing during peak hours. The study concludes that passenger satisfaction in SGR operations is multidimensional and depends on the integration of staff responsiveness with other service quality factors such as scheduling and facility standards. It recommends continuous staff training, improved communication systems, and coordinated service delivery to enhance passenger experience.

Abstract

This study assessed the influence of customer service quality on supply chain performance in logistics firms in Tanzania, focusing on the five dimensions of service quality: responsiveness, reliability, empathy, assurance, and tangibility. A correlational research design was employed to measure the relationships among these variables. Data were collected from 233 employees across Tanzania Electric Supply Company Limited (TANESCO), Simba Logistics, and Raphael Logistics using structured questionnaires based on the SERVQUAL model, with responses measured on a five-point Likert scale. Data analysis was conducted using IBM SPSS Statistics Version 27, employing both descriptive and inferential statistics. The results indicated that all five service quality dimensions had a statistically significant and positive influence on supply chain performance, with assurance and reliability demonstrating the strongest effects. The study concludes that enhancing customer service quality is crucial for improving operational efficiency, coordination, and supply chain performance. Accordingly, it recommends that logistics firms invest in regular employee training, adopt advanced technologies, maintain modern facilities, and foster professional and empathetic customer interactions to strengthen service quality and achieve sustainable supply chain competitiveness.

Abstract

This study explores the formulation of a naval mine warfare strategy as a form of forward defense in response to potential amphibious invasion threats in the strategic waters of the Riau Archipelago. Employing Colin S. Gray’s military strategy theory—which emphasizes the link between military power and political objectives—and the policy implementation theory of Mazmanian and Sabatier, the research formulates three main strategies: the phased procurement of new mine warfare vessels, the modernization of modular detection systems, and the enhancement of human resource capacity. These strategies are analyzed using a qualitative approach through SWOT analysis and are designed to involve inter-agency synergy among the Indonesian House of Representatives (Commission I), the Ministry of Defense, the Armed Forces Headquarters (Mabes TNI), and the Navy Headquarters (Mabes TNI AL) to ensure effective implementation on the ground. The findings highlight the importance of policy integration, budgetary support, and technical-operational readiness in establishing a maritime defense posture that is adaptive and responsive to regional threats

Abstract

This study examined the impact of modern technology integration on the operational efficiency of Tanzania’s Standard Gauge Railway (SGR). With growing demand for reliable, safe, and efficient rail services, the research evaluated how automation, safety and security systems, and digital ticketing platforms influence service quality and operational performance. Data were collected from 76 participants including engineers, operations managers, security personnel, ticketing officers, and passengers using structured questionnaires, with 68 responses analysed. A descriptive quantitative design was employed, utilizing descriptive statistics to capture perceptions of technology use and multiple linear regression to explore relationships between technology variables and operational efficiency. Results showed positive perceptions of technological advancements, highlighting improvements in scheduling accuracy, fraud reduction, and passenger management. However, regression analysis revealed that while technology variables had positive effects, none were statistically significant predictors of efficiency at the 5% level. Multicollinearity, particularly between automation and safety systems, was noted, indicating overlapping contributions. The study concludes that although technology has enhanced key SGR functions, its full potential remains untapped. Recommendations include improving system interoperability, enhancing staff training, and adopting integrated strategies for operational advancement. These findings offer valuable guidance for policymakers and railway stakeholders aiming to modernize and optimize Tanzania’s rail transport.

Abstract

This study investigated how different service quality dimensions affect customer satisfaction with Tanzania’s Standard Gauge Railway (SGR) services. Motivated by growing demand for efficient and customer-focused rail transport, the research employed a quantitative design, surveying 168 passengers using structured questionnaires. The objective was to understand how elements like assurance, reliability, tangibility, responsiveness, and empathy influence passenger satisfaction and to provide actionable insights for improving SGR operations. Descriptive statistics summarized passenger perceptions, while multiple regression analyzed the strength and significance of each service quality dimension’s impact. Results showed that assurance, reliability, and tangibility positively and significantly influenced customer satisfaction, highlighting passengers’ appreciation for skilled staff, dependable services, and a clean, modern railway environment. In contrast, responsiveness had a weak, insignificant effect, and empathy unexpectedly had a significant negative impact, indicating possible issues in how staff address individual passenger needs. Assurance and reliability emerged as the strongest predictors of satisfaction, followed by tangibility. The study recommends that management investigate the negative perception of empathy, potentially through staff training on inclusive and personalized care, and enhance responsiveness by improving complaint handling. Continuous investment in infrastructure and cleanliness is also advised to maintain and increase passenger satisfaction.

Abstract

Organizational transformation hinges on the effectiveness of roles executing both technical delivery and human adoption, yet current change methodologies lack a unified framework for role integration. This paper introduces the ENGAGE Star Pillars framework, a model designed to establish role governance by explicitly mapping key change functions to the six stages of the ENGAGE adoption cycle (Enlighten to Embed).The framework addresses critical inconsistencies found in existing literature—which often marginalize the Change Agent (e.g., Prosci) or omit Project and Change Manager roles (e.g., Kotter)—by unifying four essential functions under distinct, measurable pillars: Project Management (CCC framework), Sponsorship (CHAMPION), Change Management (EEE framework), and the Change Agent (BEACON). This architecture rests on the foundation of Leadership and Strategy and culminates in measurable Change Success.This study aims to clarify the specific actions and capabilities required of core roles across the entire adoption lifecycle, based on the ENGAGE Star Change Model. The ENGAGE Star Pillars framework serves as a practical, integrated governance model that eliminates accountability ambiguity, significantly accelerates adoption by coordinating the technical and people-centric efforts, and ultimately ensures the realization of strategic outcomes.
