3. MP-04b: Metodologi Penelitian Ilmu Komputer Bidang-bidang dalam Computing Apakah itu Computing – The discipline of Computing is the systematic study of algorithmic processes that describe and transform information: their theory, analysis, design, efficiency, implementation, and application. Menurut IEEE CC 2013 Computing terdiri dari – Computer Science (CS) – Computer Engineering (CE) – Information Systems (IS) – Information Technology (IT) – Software Engineering (SE)

4. MP-04b: Metodologi Penelitian Ilmu Komputer Apakah itu CS Computer Science is the study of phenomena related to computers, Newell, Perlis and Simon, 1967. Computer Science is the study of information structures, Wegner, 1968, Curriculum 68. Computer Science is the study and management of complexity, Dijkstra, 1969. Computer Science is the mechanization of abstraction, Aho and Ullman 1992. Computer Science is a field of study that is concerned with theoretical and applied disciplines in the development and use of computers for information storage and processing, mathematics, logic, science, and many other areas.

10. MP-04b: Metodologi Penelitian Ilmu Komputer Metode Ilmiah Formal – In Computing Science, formal methodologies are mostly used to prove facts about algorithms and system. Researchers may be interested on the formal specication of a software component in order to allow the automatic vercation of an implementation of that component. Alternatively, researchers may be interested on the time or space complexity of an algorithm, or on the correctness or the quality of the solutions generated by the algorithm. Experimental – Experimental methodologies are broadly used in CS to evaluate new solutions for problems. Experimental evaluation is often divided into two phases. In anexploratory phase the researcher is taking measurements that will help identify what are the questions that should be asked about the system under evaluation. Then an evaluation phase will attempt to answer these questions. A well-designed experiment will start with a list of the questions that the experiment is expected to answer. Build – A build research methodology consists of building an artifact | either a physical artifact or a software system | to demonstrate that it is possible. To be considered research, the construction of the artifact must be new or it must include new features that have not been demonstrated before in other artifacts. Process – A process methodology is used to understand the processes used to accomplish tasks in Computing Science. This methodology is mostly used in the areas of Software Engineering and Man-Machine Interface which deal with the way humans build and use computer systems. The study of processes may also be used to understand cognition in the eld of Artcial Intelligence. Model – The model methodology is centered on dning an abstract model for a real system. This model will be much less complex than the system that it models, and therefore will allow the researcher to better understand the system and to use the model to perform experiments that could not be performed in the system itself because of cost or accessibility. The model methodology is often used in combination with the other four methodologies. Experiments based on a model are called simulations. When a formal description of the model is created to verify the functionality or correctness of a system, the task is called model checking.

12. MP-04b: Metodologi Penelitian Ilmu Komputer Hal-hal penting dalam Modeling How to model? – What to take into account /neglect? -> features Is the model appropriate? – Purpose, resolution, level of abstraction Aspects of features / behavior? Difference to reality? Validation? Are the results valid? Special constraints
