    A Crowdsourcing Approach for Observation of Drinking Water Supply System
    (Uva Wellassa University of Sri Lanka, 2020) Pavithra, W.S.K.; Shihara, M.F.F.; Ranasinghe, R.M.I.S.; Ediriweera, E.P.S.K.
    Drinking water availability is a varying factor in Sri Lanka due to weather changes, natural disasters, and the breakage of pipelines. In such situations, people tend to share information regarding a lack of consumable water availability through social networks. That information is decentralized and unorganized so decision-making is difficult. The objective of this study is to represent and summarize up-to-date spatial information of drinking water availability by providing a platform for commercial water utility companies that supply water and customers to meet up and getting the general public and social service involvement. A low fidelity prototype was designed to capture the concept. To test the usability of the solution, a high-fidelity prototype was implemented for a selected set of functionalities such as social login, social sharing, viewing, and filtering posts. The web application was developed using Angular 6, Node.js web framework, and Leaflet, a free JavaScript map library. The system provides dedicated interfaces for customers to post, view information, and the user-friendly interfaces for customers to send request messages without any failures. Each request is recorded together with the geographical location, time, and tag, a search key used to filter outposts. A case study was conducted to test and evaluate the functionalities of the system and the members of the Rotaract Club in Badulla were taken for the case evaluation. The thinking aloud method was used to collect feedback and to capture the user’s thoughts while interacting with the system. Therefore, this system successfully provides a solution to the general public to gain attention on an arising water availability issue, and the commercial water utility companies are provided with a platform to advertise their services and identify areas with potential customers. A future improvement was suggested to adhere to the line and polygon data to achieve advanced Geographic Information System (GIS) features.

    Small and Medium Enterprises' Adoption of E-Commerce in Sri Lanka Case Study on Hospitality and Tourism Industry
    (Uva Wellassa University of Sri Lanka, 2018) Jayawardhana, T.M.L.T.; Hettiarachchi, J.S.; Rajapaksha, R.M.K.P.; Ellepola, C.S.D.; Ranasinghe, R.M.I.S.
    E-commerce is widely used to buy and sell products using the internet. Hospitality and tourism industry is considered as an information intensive sector. Due to the advancements in the field of IT, the hospitality and tourism industry has been able to derive the benefits of e-commerce. Even though there is a rapid development in new technologies and trends, developing countries like Sri Lanka are still facing an attitudinal barriers in accepting of e-commerce. This research was carried out with the objective of finding the factors that affect the e-commerce adoption of small and medium enterprises related to hospitality and tourism industry in Sri Lanka. A sample selected from small and medium scaled hotels and guest houses registered under the Sri Lanka Tourism Development Authority. Questionnaire and interview methods were used for the purpose of gathering data. The data were analysed using statistical tools and the received information was further processed to derive the main factors affecting the e-commerce adoption. The results of this research show that organizational readiness, attitudes and awareness of the enterprises make a strong impact on e-commerce adoption in Sri Lanka. Financial and technological resources and employee interest were the most influential factors identified under organizational readiness, while government rules and regulations and competitive pressure were the main factors that were recognized under external environmental factors. The knowledge regarding the advantages of using e-commerce was the crucial factor identified under awareness of the enterprise. After carefully analyzing these factors and reviewing related literature, a theoretical framework was developed to depict these main factors which have an impact on e-commerce adoption of small and medium enterprises in hospitality and tourism industry in Sri Lanka. This research recommends small and medium enterprises in the field of hospitality and tourism industry to pay attention to the above factors when adopting e-commerce in their respective enterprises.

    Smart Dustbin with a Web Based Point Reward System for Waste Management
    (Uva Wellassa University of Sri Lanka, 2018) Maduranga, G.K.C.D.; Gayanthika, W.A.L.; Silva, A.I.S.; Wickramarathne, S.D.H.S.; Ranasinghe, R.M.I.S.
    Sri Lanka is facing urbanization with the impact of globalization, which has results in an increase of needs and wants of people and increasing living standards of people tremendously. This economic and social advancement has resulted in a large amount of waste production in the urban areas of the country. The Government is still struggling to find a mechanism to manage this vast waste amount. The main issue government faces when managing waste is collecting pre-categorized garbage at collection points. The main reason behind this issue is lack of motivation of people to put garbage in to correct dustbins. The lack of mechanism to make aware the garbage collection center when the dustbins are full is another problem in current waste collection process. The researchers propose an Arduino based smart dustbin to overcome the above mentioned issues. The smart dustbin is integrated with a RFID reader which can identify its users and opens its lid only for the authorized users. A set of smart dustbins are assigned to certain number of households depending on their waste amount. When the user dump garbage in to the dustbin, the dustbin will measure the weight of the garbage using a load-cell and the user will be rewarded with eco points if a user dumps according to the relevant categories of garbage. Users can convert these eco points to financially benefited offers. The user can view their point balance and their details by accessing their profile through a web site. When the dustbin reaches its overflow level it is identified using an ultrasonic sensor and using a GSM module the relevant authorities are notified with a text message that the dustbin is full and about to overflow. These notifications help authorities to make the waste collection process smooth and effective. Eco points collection mechanism motivate people to dispose garbage in to categories and the smart dustbin make the waste collection process more effective and smooth. If the government involve in replacing conventional dustbin with this smart dustbin, this system will be an environmentally acceptable and economically feasible solution for the disposal of solid waste in Sri Lanka.
