Ringkasan	The diary method is a data-collection technique in which participants record their thoughts, behaviours, events, or experiences in their own words at regular or event-contingent intervals over a defined study period. By capturing data close in time to the event, diaries reduce retrospective recall bias and give researchers access to the texture of everyday life as it unfolds — something one-off surveys and retrospective interviews cannot provide.	Non-participant observation is a data-collection method in which the researcher observes behavior, interactions, or events in a natural or structured setting without joining or influencing the activity under study. The observer maintains a deliberate distance from participants to minimize their own effect on the phenomena being recorded, producing field notes, behavioral tallies, or recordings that reflect naturally occurring behavior rather than behavior shaped by researcher involvement.
