"Reka bentuk kajian" refers to a systematic and specific design approach for data collection, based on a clear and logical plan to address research problems [1] [5]. It is a methodology used to structure research studies, and it guides researchers towards achieving the objectives of their investigations [7] [8].

The design of a research study involves several considerations, such as the research problem and the field of information policy [2]. There are various types of research designs, including descriptive, causal, single-factor, and matched designs [3]. Each design has its own unique features and is suitable for different research scenarios.

For instance, in the context of evaluating the effectiveness of a specific material, a "reka bentuk penukar-gantian" (exchange design) study can be conducted [6]. This involves testing the material against a set of samples to assess its performance.

In summary, "reka bentuk kajian" is a crucial aspect of research methodology, providing a structured framework for data collection and analysis.
