    Lightweight Full-stack Web-based Solution for An Educational Organization
    (Faculty of Computing and Technology, University of Kelaniya Sri Lanka, 2022) Bandara, J.M.C.M.; Wijegunasekara, M. Carmel
    This paper discusses the web application of the Zonal Education Office, Katugastota and the development and deployment process. The problem statement is discussed using two main parts. They are organizational problems and general problems. The organizational problems discuss the current problems in the organization which needed to be overcome using a web application. The general problems describe the problems that the majority of the organizational web applications were facing. Considering the problem domain, the main aims and objectives were identified. Consequently, the proposed web application provides a lightweight, customizable, usable, cost-effective and secure web experience to the client by ensuring improved decision supportability, productivity and user experience for the organizational stakeholders. The lightweight approach benefited to use of a small amount of disk space for greater productivity, and reduce the loading time of the overall web application. LAMP stack was used to develop this web application. Furthermore, this web application used a few SaaS (Software As a Service). This web application was tested over unit testing, integration testing, system testing and user acceptance testing. The evaluation of the web application was done by design review, questionnaire and comparing similar systems. Since the client was satisfied with the current functionality of the final web application, the web application was deployed.

    Ontology Based Knowledge Management Portal for Coconut Plantation Care
    (Faculty of Computing and Technology, University of Kelaniya Sri Lanka, 2022) Ganeshakumaran, Saraga; Wijegunasekara, M. Carmel; Vishwajith, Tharuka
    Coconut (Cocos nucifera) is one of Sri Lanka's most significant plantation crops. Different coconut tree parts are used for numerous activities. Decision making is critical in the treatment method of coconut plantation. So, ontology modelling will help in decision making to diagnose causes and treatment methods easily. It is designed and developed to support agriculture engineers, coconut planters, and researchers. The ontology model is designed by using the Delphi method. Data was collected from research papers, articles, coconut research institute’s websites, and through the discussion with farmers, agriculture experts, and coconut research officers. The ontology model is evaluated and validated by tools OOPS! Evaluation editor, DL query & SPARQL Query, and ontology experts. Future work is planned to develop a knowledge management system for the coconut plantation care.
