User Requirements in Enterprise Resource Planning Systems Adoption: A Case of Botswana’s Higher Institutions
Get PDFERP systems are the largest software applications adopted by universities, along with quite significant investments in their implementation. However, unlike other applications, limited research has been conducted regarding the application of this system in higher education in Botswana. This study aims to identify user requirements in the adoption of enterprise resource planning (ERP) systems in Botswana’s higher education institutions. This study was conducted in three higher education institutions in Botswana. This study adopted the quantitative methodology of using surveys to understand ERP adoption in higher education and proposed a model that could be used to guide business information systems requirements to appropriate ERP systems in a higher educational environment. Based on the findings, the study proposed a conceptual model of ERP system adoption in higher education institutions using six success dimensions. The six success dimensions are user requirements, user satisfaction, information quality, service quality, institutional impact, system quality, and faculty/management impact. Only information quality was rejected from the model. The six success dimensions are the basis through which a higher education institution can understand user requirements in implementing an effective ERP

An IoT-Based Model for Monitoring Plant Growth in Greenhouses
Get PDFThe unstable climatic conditions are promoting the adoption of smart agriculture. The introduction of IoT technology in the cultivation process allows for the monitoring and control of plant growth through automation. While the traditional greenhouse system is already an upgrade to the traditional cultivation system, it still has room for improvement with the integration of technology. The traditional greenhouse system requires close monitoring of growth rates through manual intervention and can be prone to various hazards. Incorrect interpretations of plant requirements can result in wrong interventions that may severely affect plant growth. It is imperative to have accurate data to maintain the health of plants throughout the cultivation process. IoT plays a predominant role in providing accurate data for constant monitoring of plant growth. The aim of this paper is to present a fully functional greenhouse automation model using microcontrollers, sensors, fans, pumps, and appropriate networking routing technology capable of providing instant data for proper monitoring of plant growth. The presented model includes safety features and can issue alerts in case security measures are breached. The system may even allow users to perform remote monitoring using a web application. Therefore, the proposed model will contribute to enhancing the horticultural industry by increasing output and reducing the need for human intervention
Empowering Efficiency: A Web-Based Inventory and Sales Information System for Drinking Water Distributors through Rapid Application Development
Get PDFMicro, Small, and Medium Enterprises (MSMEs) are vital for a country's economy, fostering job creation and economic growth. This research focuses on MSME water distribution agents engaged in selling and distributing various brands and types of bottled drinking water. With a customer base exceeding a thousand and an average of 30 daily transactions, these agents encounter specific challenges in inventory and sales reporting. Presently, MSMEs rely on traditional methods, using books to record stock and sales reports, manually calculating transactions with calculators, and preparing handwritten paper invoices. These practices often result in writing errors, inaccuracies in product information, and pricing inconsistencies. Furthermore, the manual nature of these processes consumes significant time and effort on a daily basis. This study highlights the applicability of the Rapid Application Development (RAD) system design method in creating an efficient and time-sensitive solution. By leveraging RAD, the system design was swiftly accomplished with a limited team. The traceability matrix test validates the successful alignment of the designed information system with the needs of MSME agents in the drinking water distribution sector. The findings of this study provide compelling evidence that the RAD system design approach significantly enhances inventory and sales management practices for MSMEs involved in drinking water distribution. By implementing the developed information system, MSME agents can streamline their operations, eliminate manual errors, and improve overall efficiency, thereby fostering their growth and success in the market
Investigation of Relationship Between Google Cost-Per-Click and Search-Volume on Keyword of Chicago Tours
Get PDFPay-per-click is one of common and important ways in online advertising through Google; but some keywords are usually expensive and this issue is visible through Google cost-per-click in Google keyword planner tool. It has done many research work in Google advertising formats, but place of studies in field of relationship between Google cost-per-click and keyword search-volume, especially in tourism area is blank. This paper tries to answer of this main question that is there a significant relationship between cost-per-click and keyword search-volume and the number of keyword's word? In other words, does cost-per-click increase or decrease, based on keyword search-volume and the number of keyword's word (multi-word keyword or hyper focused keyword phrases)? Chicago auspicates a mighty increase in tourism 2022 as its announcement an 86 percent growth in visitors in 2021 compared to 2020 and choosing the right keyword in Google search engine by travel agencies can lead to more sales. In this research, I sampled 100 search result through combination of ″chicago+tours″ as a search keyword on google.com (Google USA) and Google keyword planner daily data (December 26, 2022) based on the last 7-10 days, and via regression analysis with least squares and loess model, I tried to investigate the relationship between search-volume and cost-per-click and it will help scholars in future research in this area. This study was carried out within the scope of selected keyword in tourism area in form of cross-sectional. I find that there is no significant relationship between short-tail keywords and cost-per-click. The result of this research shows that some medium or long-tail keywords are more expensive than short-tail keywords with more search results. Another result that was observed is the lack of significant relationship between keyword search-volume and its cost-per-click, so that in some cases, high-search keywords are cheaper than keywords with a low-search
