<![CDATA[As online learning resources increase exponentially on the World Wide Web, online students have difficulty choosing the most suitable and relevant learning material that meets their learning needs due to information overload. Online learning recommendation system is used to predict the preferences or ranking of learners' targets on learning objects for the purpose of generating recommendations. However, the Recommendation system is considered to lack the ability to resolve semantic interoperability issues with heterogeneous sources of information. The purpose of this study is to discuss the role of ontology in the development of recommendation systems in the online learning domain. There are four electronic journal databases selected as references, namely IEEE, Science Direct, Springer Link, and ACM Digital Library. This study obtained 9 articles that were synthesized to answer research questions. This study shows that the involvement of ontology for knowledge representation in the recommendation process can improve the accuracy and quality of recommendations and at the same time help to overcome the weaknesses associated with conventional recommendations.]]>

<![CDATA[Machine learning application demand is increased massively because it provides good ability in the classification that is needed by decision makers. Machine learning application uses a programming language with strong characteristics in computing, usually the back-end programming language, such as Matlab, Python, R, etc. The obstacle faced by the decision support system developer is preparing an interface that makes it easy for the user. Some back-end programming languages have provided a good interface. Therefore, in this study they were compared by taking the case of a scholarship decision support system. The language used is Python with two web-based applications including Google Interactive Notebook and Flask framework. Both devices have their respective advantages and are worthy of being the first choice in the design of decision support systems.Python has advantages with framework Flask support and Matlab is easy in interface design.]]>

<![CDATA[Searching for appropriate land for a specific purpose is important, especially in a city. Some studies used multicriteria analysis searching for the best location, such as AHP, ANP, SAW, etc. However, the study usually uses some statistical methods that need more processing for the end-users. This study uses a Geographic Information System (GIS) to implement the multicriteria analysis for searching the proper land use location, especially for business and education in Bekasi City, West Java, Indonesia. Same layers for analysis were created using ArcGIS 10.1, including pollution, road, flood risk, open space/park, lake and recreation area, and land price. The weight-overlay method was used as a multicriteria method. The result showed the three regions for business and education, i.e. high, medium, and low suitability. The conversion from the region into administrative boundary is generated in order easy for local land-use planners to implement their plans.]]>
