The keyword phrase "911 depok" functions grammatically as a proper noun. It refers to a specific entity: the emergency response system or service designated for the city of Depok. This classification is essential as it frames the subject as a singular, identifiable institution or program.
The term is a compound noun formed by two distinct proper nouns. "911" is the identifier for an emergency telephone number, widely recognized and functioning as the name of a service. "Depok" is the proper noun for a specific geographical location. In this construction, "Depok" serves as a noun adjunct, a noun that modifies another noun. It specifies the scope of the emergency service, distinguishing it from any other "911" system. The entire phrase, therefore, names a unique concept: the emergency service pertinent to Depok.
Establishing this term as a proper noun is a crucial first step for the article. It dictates that the content should focus on a specific, named entity. This allows for a direct analysis of its official name (e.g., Layanan Panggilan Darurat 112 Depok), operational procedures, contact details, and public function, rather than a general discussion of emergency services. This grammatical precision ensures the article is focused, informative, and treats its subject with the specificity it requires.
